Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3 % (11/72), and gray zone rate was 18.1 % (13/72). 31.9 % (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67 %. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.展开更多

Methods: The experimental animals were randomly divided into three groups, normal, model and curcumin group. Chronic urinary tract infection models were built for model group and curcumin group by injecting coliform fluid into the cavity of bladder. From the first day of modeling, rats in the curcumin group were injected with 150 mg/kg curcumin, while rats in normal group and model group were given no other treatment. The treatment lasted for 14 d. The white blood cell counts in blood and urine, bacterial colony count in urine and renal tubular functional indexes of rats in all groups at day I, 7, and 14 after treatment were detected. Urine beta 2-microglobulin (beta 2-MG), urinary N-acetyl-D glucosaminidase (NAG) levels were used to detected the inflammatory cytokines in serum after treatment including the contents of IL-6, IL-8, IL-10 and monocyte chemoattractant protein-I(MCP-1), and real-time PCR was employed to determine the expression of mRNA of toll-like receptor 2(TLR-2) and TLR-4 in renal tissues and bladder tissues of all groups after treatment. Results: The white blood cell counts at day I and 7 after treatment in rats of model group and curcumin group were significantly higher than those of normal group at the same time points, while the white blood cell counts of the curcumin group were significantly lower than those of model group (P < 0.05). The urine white blood cell counts in rats of model group at day 1, 7 and 14 were all significantly higher than those of normal group at the same time points: those in the curcumin group were significantly lower than those of the model group at day I, 7 and 14 at the same time points (p < 0.05). The bacterial colony counts of urine in rats of model group and curcumin group at day I. 7 and 14 were all significantly higher than those of normal group at the same time points, while the counts of curcumin group were significantly lower than those of model group at the same time points (P < 0.05). Levels of urine beta 2-MG, NAG, IL-6, IL-8, IL-10, MCP-1 and expression of TLR2 mRNA and TLR4 mRNA in renal and bladder tissues in rats of model group were significantly higher than those of the normal group, while these variables of the cercumin group were significantly higher than those of the normal group but lower than those of model group (P < 0.05). Conclusions: Curcumin can significantly improve the symptoms of chronic urinary tract infections. protect renal tubular function, and also decline inflammatory responses by influencing the expressions of TLR2 mRNA and TLR4 mRNA so as to exert its curative effect on chronic urinary tract infections.展开更多

The patients were randomly allocated to two groups: an individualized Chinese medicine group(n = 114) and a control group(n = 116). Patients in the Chinese medicine group received individualized Chinese herbs, which were evaluated for syndrome differentiation.Patients in the control group received antibiotic treatment combined with a Chinese medicine placebo. The duration of treatment was three courses of four weeks each, with a three-month subsequent follow-up. UTI recurrence rate,Traditional Chinese Medicine(TCM) syndrome scores,36-item Short Form Survey(SF-36) score, and urine secretory immunoglobulin A(SIgA) were measured and analyzed before and after treatment in each group. RESULTS: Patients from the Chinese medicine group exhibited significant decreases in both short-and longterm UTI recurrence rates compared with the control group(P < 0.05). The changes in TCM syndrome scores between the Chinese medicine and control groups were significant(P < 0.05). The changes in the average SF-36 quality-of-life scores in the Chinese medicine group were also significantly higher than those in the control group after treatment(P < 0.05). The Chinese medicine group also demonstrated a significant increase in urine SIg A expression. CONCLUSION: Taken together, compared to the oftenused long-term antimicrobial prophylaxis during the remission stage of r UTIs, treating patients with an individualized Chinese medicine decoction by syndrome differentiation could effectively reduce the recurrence rate, improve the patients' TCM syndrome scores and quality of life, and enhance immunity, which in turn helps to prevent antibiotic resistance.展开更多

This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.展开更多

文摘Background:Studies have shown that individuals who receive early treatment for rheumatoid arthritis(RA)are more likely to approach life positively,avoiding joint damage and the need for joint replacement surgery.The diagnosis of early rheumatoid arthritis(ERA)is crucial for effective treatment and prognosis of patients.Urine,as a diagnostic medium,offers the advantages of non-invasive diagnosis.Urinary metabolites can serve as biomarkers for diagnosis,prognosis,and risk prediction,improving specificity and accuracy.Methods:We recruited 37 ERA patients with a history of less than 3 months and a score of 6,26 osteoarthritis(OA)patients,and 30 healthy controls(HC).Urine samples were collected for 16S rRNA sequencing,and untargeted liquid chromatography-mass spectrometry(LC-MS)was used to detect metabolites.Bioinformatics approaches were employed to identify pathogenic metabolites as specific risk factors for ERA precisely.Results:2-methylnaphthalene was identified as a biomarker for ERA in urine.Prevotella,a major part of the urinary microbiome in ERA patients,exhibited a positive correlation with 2-methylnaphthalene.Notably,there were significant variations in urine metabolites among patients with ERA,OA,and HC.2-Methylnaphthalene was found to be significantly enriched in ERA.Besides,inflammatory factors were elevated in ERA patients.The research further demonstrated a positive correlation between rheumatoid factor(RF),erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP)and the metabolite 2-methylnaphthalene.Conclusion:The urine metabolite 2-methylnaphthalene can be a risk factor for early urinary tract infections and may contribute to accurately screening early-risk metabolites in ERA.
文摘Objective:To investigate the preventive effect of evidence-based preventive nursing on urinary tract infections(UTIs)in elderly female diabetic patients.Methods:Seventy-nine elderly female diabetic patients admitted to our hospital from March 2023 to March 2025 were selected and randomly divided into observation group(40 cases)and control group(39 cases)using the envelope method.The control group received routine nursing,while the observation group received evidence-based preventive nursing.The outcomes were compared between the two groups.Results:After treatment,blood glucose levels in both groups were significantly reduced,and the improvement in various indicators in the observation group was better than that in the control group(P<0.05).Additionally,quality of life scores were significantly improved in both groups,with the observation group showing better improvement than the control group(P<0.05).The duration of catheter indwelling and hospital stay in the observation group were lower than those in the control group(P<0.05).Conclusion:Evidence-based preventive nursing can systematically reduce the risk of urinary tract infections,improve patient outcomes,and provide effective references for clinical nursing practice.
文摘Background:Urinary tract infections(UTIs),primarily caused by uropathogenic Escherichia coli(UPEC),are a significant global health concern.The complications arise from antibiotic resistance and biofilm formation,which reduce the effectiveness of conventional treatments.This study aims to evaluate the antibiofilm activity of the homeopathic medicine Terebinthinae oleum in potencies 30C,200C,and 1M against UTI-causing E.coli,and to compare its effectiveness with the standard antibiotic Gentamycin.Methods:An in-vitro biofilm model was employed.E.coli biofilms were cultivated in microtiter plates and treated with Terebinthinae oleum(30C,200C,1M)and Gentamycin.Biofilm biomass was assessed through crystal violet staining,and optical density(OD)was measured using an ELISA microplate reader.Results:Among the tested potencies,Terebinthinae oleum 30C showed the most prominent inhibitory activity on E.coli biofilms.The inhibition percentage was compared with Gentamycin as a control.Terebinthinae oleum 30C demonstrated 41.88%inhibition of biofilm biomass,while Gentamycin exhibited up to 78.98%inhibition.Higher potencies of Terebinthinae oleum(200C and 1M)showed reduced activity(30.15%and 24.81%,respectively).Conclusion:Terebinthinae oleum,especially at 30C potency,exhibits measurable antibiofilm activity against E.coli,although less effective than Gentamycin.These findings support its use as a complementary therapy in managing biofilm-associated UTIs,justifying further clinical and immunological research.

文摘Colorectal cancer is a common tumor of the digestive system and is the third leading cause of cancer-related death worldwide.The global incidence of colorectal cancer is currently increasing.In some patients,the tumor has already spread to nearby organs at the time of diagnosis,with the small intestine and bladder being common sites of invasion.[1,2]The diagnosis of colorectal cancer that has spread to the bladder can be challenging.Aside from a few patients who experience urinary symptoms due to invasion of the bladder trigone or the entire bladder wall,there are no distinct clinical signs,which often leads to misdiagnosis.The following case report details one such instance.
文摘Objective:This study aims to develop a drug controlled-release system based on nano-hydrogel technology for stone dissolution and evaluate its dual efficacy in synchronously dissolving calcium oxalate stones and inhibiting uropathogenic Escherichia coli.Methods:A pH-responsive chitosan(CS)-sodium alginate(SA)-hydrogel microsphere loaded with potassium sodium hydrogen citrate and fosfomycin(CS/SA@PSHC@CS@F)was constructed using ionic cross-linking.In vitro stone dissolution experiments were conducted to determine drug release kinetics and stone mass reduction rate under different pH environments,and the antibacterial activity against E.coli ATCC 25922 was evaluated using the plate counting method.A rat model of kidney stone combined with infection was established.Stone volume changes were quantified via micro-CT,urinary interleukin-6(IL-6)and tumor necrosis factorα(TNF-α)levels were measured by ELISA,and renal tissue inflammation was scored via histopathological evaluation.Results:The 24-hour cumulative release rate of CS/SA@PSHC@CS@F at pH 5.8 reached 92.3%±4.1%,significantly higher than at pH 7.4(31.2%±3.7%,P<0.01).At 72 h,the mass reduction rate of calcium oxalate stones in CS/SA@PSHC@CS@F was 68.9%±5.2%,significantly higher than that of the PSHC+F mixture(P<0.01).Antibacterial experiments confirmed that the inhibition rate of biofilm colonies by CS/SA@PSHC@CS@F could reach 82.4%±6.7%,compared to 58.2%±5.3%for F,with a statistically significant difference(P<0.01).Animal experiments showed that the stone volume reduction rate in the CS/SA@PSHC@CS@F group was62.3%±8.1%,higher than that in the PSHC+F group,and the decrease in urinary IL-6 level after administration was more significant,while there was no significant difference in TNF-αlevel compared with the other two groups(P>0.05).The renal tissue inflammation score decreased to 2(1,2)points,showing a significant reduction compared with the other two groups(P<0.05).Conclusion:The novel controlled-release system designed in this study achieves targeted drug release in the stone infection microenvironment through the ion exchange mechanism,simultaneously enhancing stone dissolution efficiency and antibacterial effect,thereby providing a new drug delivery strategy for the treatment of urinary stones combined with infection.
文摘BACKGROUND Urinary tract infections(UTIs)in kidney transplant patients are a challenge.AIM To evaluate epidemiology,clinical status,therapeutic management,and clinical outcome of kidney transplant patients in a university hospital for UTI.METHODS We conducted a retrospective observational study,enrolling all kidney transplant patients hospitalized for UTI,with the objective to evaluate the epidemiology,clinical status,therapeutic management,and clinical outcome of kidney transplant patients.RESULTS From our real-life experience,infection with multidrug-resistant germs was confirmed as a risk factor for the severe evolution of the infection.At the same time,the re-evaluation of immunosuppressive therapy could be an important therapeutic strategy in the course of infection.CONCLUSION Prompt initiation of empiric antibiotic therapy upon initiation of microbiological investigations may reduce the risk of severe infection progression.
文摘Urinary tract infections(UTIs)are the most common bacterial infections.Escherichia coli is the most common cause of UTIs,accounting for 50%of hospital-reported and 90%of community-reported cases.Also,this includes species of Klebsiella,Proteus,Acinetobacter,Pseudomonas,Staphylococcus,Streptococcus,and Enterococcus.Patients experience cystitis,polyuria,and dysuria.If untreated,this affects the kidneys,further leading to septicemia.UTIs majorly affect adult females(40%-60%).Microbiological culture has been proven to be the standard method.However,it takes 48-72 hours for the tests to be reported.In cases of recurrent UTI,it is mandatory to have a quick,sensitive,and specific diagnostic procedure.Dipstick tests are considered early methods for diagnosing UTIs;however,they have limitations.Recently,biomarkers are being used to assess the severity of the disease.To achieve the United Nations Sustainable Development Goals 3 and 8,the expertise from General Medicine,Biotechnology,and Microbiology come together in achieving the set targets by 2030.In addition to diagnosis of UTI,resistance to antibiotics should not be neglected.This review aimed to examine the clinical relevance of biomarkers such as neutrophil gelatinase-associated lipocalin,kidney injury molecule-1,interleukin(IL)6,IL-8,heparin-binding protein,procalcitonin,lipopolysaccharide-binding protein,xanthine oxidase,cell-free DNA,and transrenal DNA.

文摘Background:The burden of common urologic diseases,including benign prostatic hyperplasia(BPH),urinary tract infections(UTI),urolithiasis,bladder cancer,kidney cancer,and prostate cancer,varies both geographically and within specific regions.It is essential to conduct a comprehensive and precise assessment of the global burden of urologic diseases.Methods:We obtained data on incidence,prevalence,mortality,and disability-adjusted life-years(DALYs)for the aforementioned urologic diseases by age,sex,location,and year from the Global Burden of Disease(GBD)2021.We analyzed the burden associated with urologic diseases based on socio-demographic index(SDI)and attributable risk factors.The trends in burden over time were assessed using estimated annual percentage changes(EAPC)along with a 95%confidence interval(CI).Results:In 2021,BPH and UTI were the leading causes of age-standardized incidence rate(ASIR)and age-standardized prevalence rate(ASPR),with rates of 5531.88 and 2782.59 per 100,000 persons,respectively.Prostate cancer was the leading cause of both age-standardized mortality rate(ASMR)and age-standardized DALYs rate(ASDR),with rates of 12.63 and 217.83 per 100,000 persons,respectively.From 1990 to 2021,there was an upward trend in ASIR,ASPR,ASMR,and ASDR for UTI,while urolithiasis showed a downward trend.The middle and low-middle SDI quintile levels exhibited higher incidence,prevalence,mortality,and DALYs related to UTI,urolithiasis,and BPH,while the high and high-middle SDI quintile levels showed higher rates for the three cancers.The burden of these 6 urologic diseases displayed diverse age and sex distribution patterns.In 2021,a high body mass index(BMI)contributed to 20.07%of kidney cancer deaths worldwide,while smoking accounted for 26.48%of bladder cancer deaths and 3.00%of prostate cancer deaths.Conclusions:The global burden of 6 urologic diseases presents a significant public health challenge.Urgent international collaboration is essential to advance the improvement of urologic disease management,encompassing the development of effective diagnostic screening tools and the implementation of high-quality prevention and treatment strategies.
文摘Summary: In order to study the association between lower urinary tract infection and cystitis glandularis (CG), 120 cases of CG were diagnosed by cystoscopic biopsy in the suspicious foci of the bladder. Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3 % (11/72), and gray zone rate was 18.1 % (13/72). 31.9 % (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67 %. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.

文摘Objective: To analyze the invention effect of curcumin on chronic urinary tract infection in rats and explore its possible mechanism of action. Methods: The experimental animals were randomly divided into three groups, normal, model and curcumin group. Chronic urinary tract infection models were built for model group and curcumin group by injecting coliform fluid into the cavity of bladder. From the first day of modeling, rats in the curcumin group were injected with 150 mg/kg curcumin, while rats in normal group and model group were given no other treatment. The treatment lasted for 14 d. The white blood cell counts in blood and urine, bacterial colony count in urine and renal tubular functional indexes of rats in all groups at day I, 7, and 14 after treatment were detected. Urine beta 2-microglobulin (beta 2-MG), urinary N-acetyl-D glucosaminidase (NAG) levels were used to detected the inflammatory cytokines in serum after treatment including the contents of IL-6, IL-8, IL-10 and monocyte chemoattractant protein-I(MCP-1), and real-time PCR was employed to determine the expression of mRNA of toll-like receptor 2(TLR-2) and TLR-4 in renal tissues and bladder tissues of all groups after treatment. Results: The white blood cell counts at day I and 7 after treatment in rats of model group and curcumin group were significantly higher than those of normal group at the same time points, while the white blood cell counts of the curcumin group were significantly lower than those of model group (P < 0.05). The urine white blood cell counts in rats of model group at day 1, 7 and 14 were all significantly higher than those of normal group at the same time points: those in the curcumin group were significantly lower than those of the model group at day I, 7 and 14 at the same time points (p < 0.05). The bacterial colony counts of urine in rats of model group and curcumin group at day I. 7 and 14 were all significantly higher than those of normal group at the same time points, while the counts of curcumin group were significantly lower than those of model group at the same time points (P < 0.05). Levels of urine beta 2-MG, NAG, IL-6, IL-8, IL-10, MCP-1 and expression of TLR2 mRNA and TLR4 mRNA in renal and bladder tissues in rats of model group were significantly higher than those of the normal group, while these variables of the cercumin group were significantly higher than those of the normal group but lower than those of model group (P < 0.05). Conclusions: Curcumin can significantly improve the symptoms of chronic urinary tract infections. protect renal tubular function, and also decline inflammatory responses by influencing the expressions of TLR2 mRNA and TLR4 mRNA so as to exert its curative effect on chronic urinary tract infections.

文摘OBJECTIVE: To systematically assess the effects of individualized Chinese medicines on recurrent urinary tract infections(rUTIs).METHODS: This study recruited 230 adult female patients in the remission phase of rUTIs from five hospitals in China. The patients were randomly allocated to two groups: an individualized Chinese medicine group(n = 114) and a control group(n = 116). Patients in the Chinese medicine group received individualized Chinese herbs, which were evaluated for syndrome differentiation.Patients in the control group received antibiotic treatment combined with a Chinese medicine placebo. The duration of treatment was three courses of four weeks each, with a three-month subsequent follow-up. UTI recurrence rate,Traditional Chinese Medicine(TCM) syndrome scores,36-item Short Form Survey(SF-36) score, and urine secretory immunoglobulin A(SIgA) were measured and analyzed before and after treatment in each group. RESULTS: Patients from the Chinese medicine group exhibited significant decreases in both short-and longterm UTI recurrence rates compared with the control group(P < 0.05). The changes in TCM syndrome scores between the Chinese medicine and control groups were significant(P < 0.05). The changes in the average SF-36 quality-of-life scores in the Chinese medicine group were also significantly higher than those in the control group after treatment(P < 0.05). The Chinese medicine group also demonstrated a significant increase in urine SIg A expression. CONCLUSION: Taken together, compared to the oftenused long-term antimicrobial prophylaxis during the remission stage of r UTIs, treating patients with an individualized Chinese medicine decoction by syndrome differentiation could effectively reduce the recurrence rate, improve the patients' TCM syndrome scores and quality of life, and enhance immunity, which in turn helps to prevent antibiotic resistance.
文摘BACKGROUND Urinary tract infection(UTI)is a common type of postoperative infection following cytoreductive surgery for ovarian cancer,which severely impacts the prognosis and quality of life of patients.AIM To develop a machine learning assistant model for the prevention and control of nosocomial infection.METHODS A total of 674 elderly patients with ovarian cancer who were treated at the Department of Gynaecology at Jingzhou Central Hospital between January 31,2016 and January 31,2022 and met the inclusion criteria of the study were selected as the research subjects.A retrospective analysis of the postoperative UTI and related factors was performed by reviewing the medical records.Five machine learning-assisted models were developed using two-step estimation methods from the candidate predictive variables.The robustness and clinical applicability of each model were assessed using the receiver operating characteristic curve,decision curve analysis and clinical impact curve.RESULTS A total of 12 candidate variables were eventually included in the UTI prediction model.Models constructed using the random forest classifier,support vector machine,extreme gradient boosting,and artificial neural network and decision tree had areas under the receiver operating characteristic curve ranging from 0.776 to 0.925.The random forest classifier model,which incorporated factors such as age,body mass index,catheter,catheter intubation times,blood loss,diabetes and hypoproteinaemia,had the highest predictive accuracy.CONCLUSION These findings demonstrate that the machine learning-based prediction model developed using the random forest classifier can be used to identify elderly patients with ovarian cancer who may have postoperative UTI.This can help with treatment decisions and enhance clinical outcomes.
文摘Radical hysterectomy(RH) and pelvic lymphadenectomy are the main treatment methods for early cervical cancer and endometrial carcinoma.Effective care measures,however,can decrease the incidence of UTIs and complications associated with RH and pelvic lymphadenectomy,as well as improve the therapeutic effects of administered drugs and patient prognosis.The writer refers to relevant literatures to analyze the reasons for postoperative UTIs and to provide a brief summary of the nursing methods for and progress in UTI prevention.
文摘Background and Aims: Urinary tract infections (UTIs) are common among pregnant women and major predisposing factors for pyelonephritis linked to obstetrical complications including preterm labour and low infants’ birth weights. This study sought to determine the relationship(s) between pregnancy trimesters, UTIs and changes in progesterone levels among pregnant women. Materials and Methods: The study was conducted in 2016 at Moi Teaching and Referral Hospital (MTRH) antenatal clinic which is a referral facility that attends to patients from most Counties in western region of Kenya. A cross-sectional study design was used to collect blood and urine specimens from 78 participants. Blood was used to determine progesterone levels using ELISA technique and urine cultures with bacterial colony counts ≥ 10<sup>5</sup> were appropriately identified to species level. Trimester periods and participants’ demographic information were obtained using a structured questionnaire. Results: Culture results showed that the most abundant bacterial species isolated in urine from the pregnant women was Escherechia coli (63.7%). The more affected age-group was women between 30 - 39 years during trimester three, suggesting that bacterial colonization of genital track occurred more frequently in older compared to the younger women. There was an exponential increase in progesterone levels among the pregnant women during trimester three compared to other trimesters, although these increases occurred independent of age. However, high levels of progesterone among pregnant women in third trimester corresponded with increased number of E. coli causing UTI. Conclusion: The results showed that progesterone levels increase with trimester and the most prevalent bacteria associated with this was E. coli even though age and increase in progesterone levels had no significant impact on E. coli infection.
文摘<strong>Introduction:</strong> Urinary tract infections (UTI) are frequent and of polymorphous clinical symptomatology in elderly subjects both in and out of hospital. In Mali, to our knowledge, no study concerning UTIs in the elderly has been conducted, hence the interest in this innovative work. <strong>Objectives:</strong> To determine the prevalence and clinical and paraclinical aspects of urinary tract infections in the elderly. <strong>Materials and Methods:</strong> This was a prospective descriptive and cross-sectional study from September 1, 2013 to August 31, 2014, <i>i.e. </i> duration of 12 months. All patients aged 65 years and over, hospitalized or ambulatory in the internal medicine department with a documented urinary tract infection were included. <strong>Results:</strong> We collected and examined 194 patients. The cytobacteriological study of urine (CBSU) was positive in 28 patients, <i>i.e. </i> a prevalence of 14.43%. The male sex represented 59.8% of the cases, the sex ratio was equal to 1.46. The age groups between 65 - 69 and 70 - 74 years were the most affected, respectively 28.57% and 39.28%. The main clinical signs were: asthenia, anorexia, dependence, fever, urinary burning, dysuria. Hospitalization was associated with urinary tract infection with P = 0.01. The group of enterobacteria were incriminated in 75% of cases. <i>Escherichia coli, Klebsiella pneumoniae</i> and <i>Pseudomonas aeruginosa</i> represented 39.28%, 14.28% and 10.71% of cases. Urinary tract infections were represented by pyelonephritis, acute prostatitis, orchi-epididymitis and simple cystitis. <strong>Conclusion:</strong> Urinary tract infection is frequent in the elderly, its clinical presentation is polymorphic and enterobacteria are the most incriminated group of bacteria.
