For the needs of bladder urinary volume noninvasive monitoring in clinical, we present a noninvasive bladder urinary volume monitoring system based on bio-impedance. The system uses a four-electrode structure,which is composed of a pair of excitation electrodes and a pair of measurement electrodes. The Direct Digital Frequency Synthesis (DDS) is applied to generate a 50 kHz sine current excitation source. The impedance information extracted from phase sensibility demodulation technology is transferred to a computer through Zigbee wireless technology for real-time monitoring. Two experiments are taken to verify the accuracy and feasibility of the system. The experiments results show that the system can accurately measure the corresponding electrical impedance change of the bladder. The system provides a new way to continuously and noninvasively monitor the bladder urinary volume of patients with bladder dysfunction. 展开更多

The aim of this study is to assess the ability of serum prostate-specific antigen (PSA) to predict prostate volume (PV) and lower urinary tract symptoms (LUTS) represented by the international prostate symptom score (IPSS). From January 2001 to December 2011, data were collected from men who first enrolled in the Korean Prostate Health Council Screening Program. Patients with a serum PSA level of 10 ng ml^-1 or age 〈40 years were excluded. Accordingly, a total of 34 857 men were included in our study, and serum PSA, PV and the IPSS were estimated in all patients. Linear and age-adjusted multivariate logistic analyses were used to assess the potential association between PSA and PV or IPSS. The predictive value of PSA for estimating PV and IPSS was assessed based on the receiver operating characteristics-derived area under the curve (AUC). The mean PV was 29.9 ml, mean PSA level was 1.49 ng ml^-1 and mean IPSS was 15.4. A significant relationship was shown between PSA and PV, and the IPSS and PSA were also significantly correlated after adjusting by age. The AUCs of PSA for predicting PV ~20 ml, 〉25 ml and 〉35 ml were 0.722, 0.728 and 0.779, respectively. The AUCs of PSA for predicting IPSS 〉 7, 〉 13 and 〉 19 were 0. 548, 0.536 and 0. 537, respectively. Serum PSA was a strong predictor of PV in a community-based cohort in a large-scale screening study. Although PSA was also significantly correlated with IPSS, predictive values of PSA for IPSS above the cutoff levels were not excellent. Further investigations are required to elucidate the exact interactions between PSA and LUTS and between PSA and PV in prospective controlled studies. Such studies may suggest how PSA can be used to clinically predict PV and the IPSS. 展开更多

BACKGROUND Ureteral injury is a known complication of hysterectomies.Recent studies have attempted to correlate surgeon volume and experience with incidence of urinary tract injuries during hysterectomies.Some studies have reported that as surgeon volume increases,urinary tract injury rates decrease.To our knowledge,no studies have assessed the relationship between surgeon subspecialty and the rate of urinary tract injury rates during minimally invasive hysterectomy.AIM To determine the incidence of urinary tract injury between urogynecologists,gynecologic oncologists,and general gynecologists.METHODS The study took place from January 1,2016 to December 1,2021 at a large comm-unity hospital in Detroit,Michigan.We conducted a retrospective chart review of adult patients who underwent minimally invasive hysterectomy.After we identified eligible patients,the surgeon subspecialty was identified and the surgeon’s volume per year was calculated.Patient demographics,medical history,physician-dictated operative reports,and all hospital visits postoperatively were reviewed.RESULTS Urologic injury occurred in four patients(2%)in the general gynecologist group,in one patient(1%)in the gynecologic oncologist group,and in one patient(1%)in the urogynecologist group.When comparing high and low-volume surgeons,there was no statistically significant difference in urinary tract injury(1%vs 2%)or bowel injury(1%vs 0%).There were more complications in the low-volume group vs the high-volume group excluding urinary tract,bowel,or major vessel injury.High-volume surgeons had four(1%)patients with a complication and low-volume surgeons had 12(4%)patients with a complication(P=0.04).CONCLUSION Our study demonstrated that there was no difference in the urinary tract injury rate in general gynecologists vs subspecialists,however our study was underpowered. 展开更多

BACKGROUND Urinary system tumors often cause negative psychological symptoms,such as depression and dysphoria which significantly impact immune function and indirectly affect cancer prognosis.While epirubicin(EPI)is recommended by the European Association of Urology and can improve prognosis,its long-term use can cause toxic side effects,reduce treatment compliance,and increase psycho-logical burden.Therefore,an appropriate intervention mode is necessary.METHODS This was a retrospective study including 110 patients with urinary system tumors and depression admitted to Zhumadian Central Hospital between March 2021 and July 2023.Patients were divided into conventional(n=55)and joint inter-vention(n=55)groups.The conventional group received mitomycin and routine nursing,while the joint intervention group received EPI and mindfulness intervention.Both groups underwent three cycles of chemotherapy.Immune function(CD4+cells,CD8+cells,CD4+/CD8+ratio),tumor marker levels[urinary bladder cancer antigen(UBC),bladder tumor antigen(BTA)and nuclear matrix protein 22(NMP22)],quality of life questionnaire-core 30(QLQ-C30),17-item Hamilton depression scale(HAMD-17),and cancer-related fatigue[cancer fatigue scale(CFS)]were assessed.Adverse reactions and nursing satisfaction were recorded and evaluated.RESULTS Post-intervention,CD4+,CD8+,and CD4+/CD8+levels increased in both groups,with the joint intervention group showing more significant improvement(P<0.05).Tumor marker levels(NMP22,BTA,and UBC)were lower in the joint intervention group compared to the conventional group(P<0.05).The joint intervention group also showed a greater reduction in HAMD-17 scores(9.38±3.12 vs 15.45±4.86,P<0.05),higher QLQ-C30 scores,and lower CFS scores(both P<0.05).Additionally,the joint intervention group had a lower incidence of adverse reactions and higher nursing satisfaction(P<0.05).CONCLUSION EPI combined with mindfulness intervention significantly improved clinical outcomes in patients with urinary system tumors and depression and is worthy of clinical application. 展开更多

Purpose: We examined the relationship between the urinary ATP level and the desire to void, voided urine volume, and urinary osmotic pressure. Materials and Methods: The subjects were 4 healthy volunteers (2 men and 2 women) without micturition disorders who were not taking any medications and had normal urinalysis findings. Over 2 - 3 days, they urinated into a clean cup a total of 20 times. The strength of the desire to void was classified (none, slight, moderate, or strong;scored from 1 to 4, respectively) and a voiding score was assigned at each urination, along with measurement of the voided volume, urinary ATP, urinary creatinine, and urinary osmotic pressure (one man). Results: Variation of the urinary ATP/creatinine ratio was large in both male and female subjects. The urinary ATP/creatinine ratio was lower in the 2 men compared with the 2 women. This ratio showed a significant negative correlation (R2 = 0.1577 and 0.1673, both p < 0.05) with the voided urine volume in the male subjects. However, there was no relationship between the urinary ATP/creatinine ratio and the voiding score or voided urine volume in the female subjects. Conclusions: The urinary ATP level may not be a clinically useful marker of bladder pathology. Both the present study and our previous studies identified a large sex difference in the urinary ATP/creatinine ratio, and this finding may be important when considering the causes of overactive bladder (OAB) in women. The mechanism underlying the increase in urinary ATP in women should be investigated to develop new therapies for OAB. 展开更多

Objective:Previous studies have demonstrated that the metals cadmium and arsenic exhibit estrogen-like effects and may influence the occurrence and development of gynecological tumors.This study aims to explore the association between urinary cadmium and arsenic levels and the prevalence of gynecologic cancers using data from the National Health and Nutrition Examination Survey(NHANES).Methods:Data from female participants in NHANES 2003—2018 were analyzed.Using R software,datasets(DEMO,BMX,etc.)were merged,and complete cases were retained by intersecting row names,yielding a total of 2999 participants.After applying strict exclusion criteria,2802 participants were included:83 with gynecologic cancer(cancer group)and 2719 without(control group).Demographic,reproductive health,and urinary cadmium and arsenic data were collected.Binary Logistic regression models were employed to assess associations between urinary cadmium and arsenic levels and gynecologic cancer risk.Results:High urinary cadmium and arsenic levels were risk factors for gynecologic cancers,with odds ratios(ORs)of 1.623(95%CI 1.217 to 2.166)and 1.003(95%CI 1.001 to 1.005),respectively.After propensity score matching(PSM),the trend remained;cadmium was still a statistically significant risk factor with an OR of 2.182(95%CI 1.343 to 3.545),while arsenic’s association,though not statistically significant,still trended toward risk(OR=1.004,95%CI 0.999 to 1.009).Subgroup analyses showed that both cadmium and arsenic were risk factors for ovarian cancer(OR=1.745,95%CI 1.178 to 2.586 and OR=1.005,95%CI 1.002 to 1.008,respectively);these associations persisted after PSM.Additionally,cadmium increased the risk of endometrial cancer(OR=1.617,95%CI 1.109 to 2.356).Conclusion:Exposure to cadmium and arsenic is associated with an increased risk of ovarian and endometrial cancers.These findings suggest that reducing environmental exposure to heavy metals such as cadmium and arsenic may help prevent certain gynecologic cancers. 展开更多

Objective:Urinary calculi are characterized by a high recurrence rate,and patients’adherence to self-management after discharge directly affects health outcomes.Traditional offline follow-up models often face problems such as poor compliance and uneven allocation of medical resources,making it difficult to meet individualized health management needs.Remote follow-up provides a novel solution to optimize long-term management,improve health literacy,and enhance clinical outcomes.This study aims to evaluate the effect of remote follow-up under an intelligent medical collaborative model on quality of life and health-promoting lifestyle in patients with urinary calculi,and to assess its short-term impact on clinical outcomes.Methods:A total of 118 patients with urinary calculi admitted to a tertiary hospital in Hunan Province between August and November 2024 were recruited and randomly assigned to a control group(n=59)or an intervention group(n=59).The control group received routine departmental follow-up,while the intervention group underwent remote follow-up based on an intelligent medical collaborative model for one month.Assessments were conducted before discharge(T0),15 days after discharge(T1),and one month after discharge(T2),using the Wisconsin Stone Quality of Life Questionnaire and the Health-Promoting Lifestyle Profile.At T2,the incidence of forgotten ureteral stents(FUS),ureteral stent-related complications,unplanned readmissions,and patient satisfaction were evaluated.Results:No significant differences were observed between groups at T0 in baseline characteristics or outcome measures(all P>0.05).At T1 and T2,the intervention group had significantly higher health-related quality of life scores than the control group(P<0.05).Generalized estimating equation(GEE)analysis showed significant between-group effects(Wald's χ^(2)=22.961,P<0.001),time effects(Wald's χ^(2)=23.065,P<0.001),and interaction effects(Wald's χ^(2)=6.930,P<0.05).Similarly,at T1 and T2,the intervention group scored significantly higher on health-promoting lifestyle than the control group(P<0.05),with significant between-group effects(Wald's χ^(2)=22.936,P<0.001),time effects(Wald's χ^(2)=10.694,P<0.001),and interaction effects(Wald's χ^(2)=18.921,P<0.05).No significant differences were found between groups in the incidence of FUS,ureteral stent-related complications,or unplanned readmissions(all P>0.05).Patient satisfaction was significantly higher in the intervention group(t=4.089,P<0.001).Conclusion:Remote follow-up under an intelligent medical collaborative model helps improve quality of life,promote health-oriented lifestyles,and enhance patient satisfaction among individuals with urinary calculi. 展开更多

Objective:Stress urinary incontinence(SUI)is a common condition among women that severely impairs quality of life.Pelvic floor proprioceptive training(PFPT)has attracted increasing attention for its potential to enhance pelvic floor muscle function and alleviate SUI symptoms.This study aims to observe and compare the clinical efficacy of PFPT combined with electroacupuncture,electrical stimulation,and biofeedback therapy versus conventional therapy consisting of electroacupuncture,electrical stimulation,and biofeedback alone in women with SUI,and to explore the role of PFPT in improving symptom and functional outcomes.Methods:In this randomized controlled trial,72 women with mild to moderate SUI were recruited from the Department of Rehabilitation Medicine at Third Xiangya Hospital,Central South University,between December 2021 and October 2023.Participants were randomly assigned to an experimental group(n=36)or a control group(n=36).Both groups received health education.The control group underwent electroacupuncture combined with electrical stimulation and biofeedback therapy,while the experimental group additionally received PFPT 3 times per week for 4 weeks.The primary outcome was assessed using the International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF).Secondary outcomes included pelvic floor muscle strength,bladder neck mobility,and balance ability.The ICIQ-SF was reassessed at 1,3,6,and 12 months post-treatment.Results:Both groups showed statistically significant improvements in all parameters after treatment(all P<0.05).However,there were no statistically significant differences between groups in most measures(all P>0.05).The experimental group demonstrated longer singleleg stance duration with eyes closed than the control group(left leg:P=0.026;right leg:P=0.006),with a significant increase from baseline(P<0.001).At 6 months post-treatment,the cure rate in the experimental group was significantly higher than that in the control group(P=0.037).Conclusion:Conventional therapy effectively improves SUI symptoms,but adding PFPT provides notable additional benefits,including enhanced balance ability and sustained midterm cure rates.These findings suggest that PFPT is a valuable adjunct to standard SUI management strategies. 展开更多

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. 展开更多

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. 展开更多

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. 展开更多

This manuscript comments on the article published in a recent issue of World Journal of Psychology.We emphasize the potential of combining Epirubicin(EPI)chemotherapy with mindfulness-based interventions(MBIs)to optimize cancer care for urinary system tumors.The long-term use EPI is associated with depression and in short-term has shown side effects such as fatigue,nausea,and occasional abdominal pain,which can impact patient adherence.MBIs address the psychological burdens,such as depression and anxiety,that accompany cancer treatment,enhancing emotional well-being,immune function,and treatment adherence.Integration of MBIs alongside EPI offers improved clinical outcomes by lowering stress and reducing side effects,ultimately supporting both psychological and physical recovery.This comprehensive care model can potentially promote long-term health and quality of life for cancer patients. 展开更多

Objective:This study aimed to investigate the clinicopathological features and prognosis of small cell carcinoma of the urinary bladder(SCCUB).Methods:Clinicopathological data and prognosis of 24 patients with primary SCCUB treated at the Affiliated Hospital of Qingdao University(from January 2016 to December 2021)were retrospectively collected and compared with 335 patients with primary high-grade urothelial carcinoma(HG-UC)during the same period.The study endpoints were disease-free survival(DFS)and overall survival(OS).Results:Of the 24 patients with SCCUB,19 were male and five were female.Eight(33%)cases were pure SCCUB(pSCCUB).Sixteen(67%)cases were mixed SCCUB(mSCCUB),all of which were mixed with urothelial carcinoma.All patients underwent surgery and 13(76%,13/17;seven patients were lost to follow-up)patients received postoperative adjuvant chemotherapy.We found no significant difference in clinicopathological features between pSCCUB and mSCCUB.However,compared to HG-UC,SCCUB had higher lymph node metastasis(p=0.014),more lymphovascular invasion(p=0.024),higher Ki-67 expression(p<0.001),and more disease progression events(p=0.001).Median DFS and OS for SCCUB were 22 months and 38 months,respectively.The Kaplan-Meier survival curve showed that the pathological type or surgical type did not affect DFS or OS of SCCUB.However,SCCUB patients had worse DFS and OS than HG-UC patients(both p<0.05).The multivariate Cox analysis showed that the tumor size(hazard ratio 1.44,95%CI 1.96–2.15,p=0.048)was an independent factor affecting DFS of SCCUB patients.Conclusion:Compared with the common HG-UC,SCCUB is rare with specific clinicopathological features and a worse prognosis. 展开更多
