Two broad categories affect patient access: provider issues and patient preferences. We chose to study the previously unreported patient choices that affect access delays between the time a urology appointment is requested and the urology appointment itself. Methods: A 3-week real time telephone survey was conducted with callers seeking a urology appointment. If the callers did not choose the first available appointment, they were questioned as to why they did not. This data was then compared to a 3-month access delay graph noting the number of new patients offered each day. Results: Adult and pediatric urologic clinics were evaluated separately. For adult clinics, 14% of patients chose not to accept the first available appointments and 5% sought urologic care elsewhere. For pediatric clinics, 44% delayed access beyond the first available appointment. Of these, 26% were asked by the physician to delay in order to time appointments with imaging studies on the same day, or were advised to wait longer because of the nature of the patient’s diagnosis. Parents’ choice delayed 18% of the appointments beyond the first available appointment. Discussion: These data reveal that about 85% of new patient access falls within the provider’s control. The other 15% of delays rest on the preferences of the patients. These decisions significantly skew the access delay data that is increasingly being used to measure the quality of a urology practice.展开更多

Urine examination is done worldwide as an extension of physical examination which provides a lot of information about the pathology, and both physical and chemical analysis of urine are highly informative. There are several types of urine investigations, some of which include urinalysis, urine microscopy culture and sensitivity, urine microscopy for ova or cyst of parasites, urine cytology, urine tumour antigens assays, urine hormonal assays, urine toxicology, urine quantitative measurement and urine acid fast bacilli. Uses of urine examinations in urology could be diagnostic, such as renal function test, evaluation of heamaturia, stone diseases, urinary tract infections, urologic cancers and infertility or monitoring and for prognosis. Uses of urine investigations in practice of urology cannot be over emphasized as it has many revealing information of the physiology and pathology of urologic organs.展开更多

In this review we aimed to summarize and critically analyze the available evidence on the current status and future prospects for LESS in pediatric urology, with special emphasis on our experience with LESS in children. The clinical data available clearly demonstrate that LESS can safely and effectively be performed in a variety of pediatric urology settings. As clinical experience increases, expanding indications are expected to be documented and the efficacy of the procedure to improve. So far, the quality of evidence of all available studies remains low; mostly being small case series or case-control studies from selected centers. Thus, the only objective benefit of LESS remains improved cosmetic outcome. Prospective randomized studies are awaited to determine which LESS procedures will be established and which are unlikely to stand the test of time. Technological advances hold promise to minimize the challenging technical nature of scarless surgery. In this respect, robotics may be a driving force in the development of LESS.展开更多

Objective: To report the results of endo urology practice in Bouaké during the two practice sessions. Patients and Methods: Cross-sectional and descriptive study of patients followed up and had benefited from exploration and/or endoscopic surgery in Bouaké. Our study was carried out in a facility in Bouaké, for two years, from January 2021 to December 2022. The parameters of interest were clinical, diagnostic, endoscopic procedure and results. Results: During the study period, 157 patients underwent endoscopic exploration and/or intervention. The mean age was 58.9 years (range 28 - 90 years). Males predominated with 95.5% (n = 150). Acute urinary retention was the most frequent reason for consultation (55.41%). Benign prostatic hyperplasia (BPH) was the most frequent pathology at 22.92% (n = 36). Urethrocystoscopy was performed in 52 cases (33.12%), Transurethral resection of the prostate (TURP) in 36 cases (22.92%), Endoscopic resection of secondary cervical sclerosis in 23 cases (14.64%), Endoscopic internal urethrotomy (EUI) in 15 cases (9.55%) and Transurethral resection of the bladder (TURB) in 10 cases (6.36%). Post-operative management was straightforward in 93.63% of cases (n = 147). Operative times of between 21 and 35 minutes were more frequent in 55.41% of cases (n = 87). Urinary tract infections accounted for 3.8% (n = 6) of surgical morbidity. The germ responsible for the infections was essentially Escherichia coli (E. coli). The mean duration of post-operative urinary drainage was 5.5 days (range: 4 - 6 days) for patients who underwent TURP, TURB and endoscopic resection of secondary sclerosis of the bladder neck. The mean duration of drainage after endoscopic internal ureterotomy was 21.6 days (range 14 - 30 days). Of the 157 endoscopies performed, 154 patients (98.08%) had a favourable outcome, with adenomyofibroma of the prostate being the most common histological type (52.17%, n = 36). Mortality was 1.27% (n = 2) in our series. Conclusion: Endo urology should be the urologist’s first choice for both exploration and surgery, given the satisfactory results.展开更多

The aim of the present study is thus to evaluate the effectiveness of urological consultation by videoconference, perceptions regarding safety on the part of medical teams providing video consultation services and patient satisfaction after a urological appointment. Materials and Methods: A cross-sectional, observational, and analytical study was carried out with 50 volunteers referred from the basic health unit for a urology appointment. All patients were evaluated remotely by videoconference and in person by different urology teams. Results: The study revealed that effectiveness in terms of the degree of match between diagnoses performed by video consultation and those performed in person was 92%. The urology team’s perception regarding safety, measured using an in-house safety questionnaire, was high for both videoconferencing and in-person consultations and there was no statistical difference between the two (overall safety score for video consultation compared to in-person consultation was 9.7 ± 0.8 compared to 9.6 ± 0.8 and the p-value was 0.3 for Student’s t-test). Patient satisfaction with the appointment was similarly high for both groups, averaging 9.72 ± 0.4 among patients who attended a video consultation and 9.82 ± 0.4 among those whose consultation was conducted in person, with a p-value of 0.10478 for Student’s t-test. Conclusion: Video consultation in urology is an effective way to perform diagnoses, with high levels of perceived safety among urologists and high satisfaction rates among patients.展开更多

文摘Objective:To explore the impact of the coronavirus disease 2019(COVID-19)pandemic on the training experiences of urology residents in Indonesia.Methods:A cross-sectional study using a web-based questionnaire(SurveyMonkey)involved all registered urology residents in Indonesia.The questionnaire was structured in Bahasa Indonesia,composed of 28 questions,and divided into three sections:demographic characteristics,current daily activities,and opinions regarding training experiences during the COVID-19 outbreak.The survey was distributed to all respondents via chief of residents in each urology center from May 26,2020 to Jun 2,2020.Results:Of the total 247 registered urology residents,243 were eligible for the study.The response and completeness rate for this study were 243/243(100%).The median age of respondents was 30(range:24e38)years old,and 92.2%of them were male.Among them,6(2.5%)respondents were confirmed as COVID-19 positive.A decrease in residents’involvement in clinical and surgical activities was distinguishable in endourological and open procedures.Most educational activities were switched to web-based video conferences,while others opted for the in-person method.Smart learning methods,such as joining a national or international speaker webinar or watching a recorded video,were used by 93.8%and 80.7%of the respondents,respectively.The respondents thought that educational activities using web-based video conferences and smart learning methods were effective methods of learning.Overall,the respondents felt unsure whether training experiences during the COVID-19 pandemic were comparable to the respective period before.Conclusion:The COVID-19 pandemic negatively affected urology residents’training experiences.However,it also opened up new possibilities for incorporating new learning methodologies in the future.
文摘Objective:A major role in the establishment of computer-assisted robotic surgery(CARS)can be traced to the work of Mani Menon at Vattikuti Urology Institute(VUI),and of many surgeons of Asian origin.The success of robotic surgery in urology has spurred its acceptance in other surgical disciplines,improving patient comfort and disease outcomes and helping the industrial growth.The present paper gives an overview of the progress and development of robotic surgery,especially in the field of Urology;and to underscore some of the seminal work done by the VUI and Asian surgeons in the development of robotic surgery in urology in the US and around the world.Methods:PubMed/Medline and Scopus databases were searched for publications from 2000 through June 2014,using algorithms based on keywords“robotic surgery”,“prostate”,“kidney”,“adrenal”,“bladder”,“reconstruction”,and“kidney transplant”.Inclusion criteria used were published full articles,book chapters,clinical trials,prospective and retrospective series,and systematic reviews/meta-analyses written in English language.Studies from Asian institutions or with the first/senior author of Asian origin were included for discussion,and focused on techniques of robotic surgery,relevant patient outcomes and associated demographic trends.Results:A total of 58 articles selected for final review highlight the important strides made by robots in urology,from robotic radical prostatectomy in 2000 to robotic kidney transplant in 2014.In the hands of an experienced robotic surgeon,it has been demonstrated to improve functional patient outcomes and minimize perioperative complications compared to open surgery,especially in urologic oncology and reconstructive urology.With increasing surgeon proficiency,the benefits of robotic surgery were consistently seen across different surgical disciplines,patient populations,and strata.
文摘Introduction: Improvement in new patient access to urologic care is important and is increasingly measured as a reflection of practice quality. Two broad categories affect patient access: provider issues and patient preferences. We chose to study the previously unreported patient choices that affect access delays between the time a urology appointment is requested and the urology appointment itself. Methods: A 3-week real time telephone survey was conducted with callers seeking a urology appointment. If the callers did not choose the first available appointment, they were questioned as to why they did not. This data was then compared to a 3-month access delay graph noting the number of new patients offered each day. Results: Adult and pediatric urologic clinics were evaluated separately. For adult clinics, 14% of patients chose not to accept the first available appointments and 5% sought urologic care elsewhere. For pediatric clinics, 44% delayed access beyond the first available appointment. Of these, 26% were asked by the physician to delay in order to time appointments with imaging studies on the same day, or were advised to wait longer because of the nature of the patient’s diagnosis. Parents’ choice delayed 18% of the appointments beyond the first available appointment. Discussion: These data reveal that about 85% of new patient access falls within the provider’s control. The other 15% of delays rest on the preferences of the patients. These decisions significantly skew the access delay data that is increasingly being used to measure the quality of a urology practice.
文摘Urine examination is one of the important armamentarium in the practice of urology and it is a fundamental test that is usually carried out for urology patients, it can be as simple as dipstick analysis to a complex hormonal assays. Urine examination is done worldwide as an extension of physical examination which provides a lot of information about the pathology, and both physical and chemical analysis of urine are highly informative. There are several types of urine investigations, some of which include urinalysis, urine microscopy culture and sensitivity, urine microscopy for ova or cyst of parasites, urine cytology, urine tumour antigens assays, urine hormonal assays, urine toxicology, urine quantitative measurement and urine acid fast bacilli. Uses of urine examinations in urology could be diagnostic, such as renal function test, evaluation of heamaturia, stone diseases, urinary tract infections, urologic cancers and infertility or monitoring and for prognosis. Uses of urine investigations in practice of urology cannot be over emphasized as it has many revealing information of the physiology and pathology of urologic organs.
文摘Laparoendoscopic single-site surgery(LESS) has been developed to benefit patients by enabling surgeons to perform scarless surgery. In this review we aimed to summarize and critically analyze the available evidence on the current status and future prospects for LESS in pediatric urology, with special emphasis on our experience with LESS in children. The clinical data available clearly demonstrate that LESS can safely and effectively be performed in a variety of pediatric urology settings. As clinical experience increases, expanding indications are expected to be documented and the efficacy of the procedure to improve. So far, the quality of evidence of all available studies remains low; mostly being small case series or case-control studies from selected centers. Thus, the only objective benefit of LESS remains improved cosmetic outcome. Prospective randomized studies are awaited to determine which LESS procedures will be established and which are unlikely to stand the test of time. Technological advances hold promise to minimize the challenging technical nature of scarless surgery. In this respect, robotics may be a driving force in the development of LESS.

文摘Background: Endoscopic exploration and treatment of urinary tract disorders, whether by retrograde, percutaneous or endoscopic approach, defines endo urology. Objective: To report the results of endo urology practice in Bouaké during the two practice sessions. Patients and Methods: Cross-sectional and descriptive study of patients followed up and had benefited from exploration and/or endoscopic surgery in Bouaké. Our study was carried out in a facility in Bouaké, for two years, from January 2021 to December 2022. The parameters of interest were clinical, diagnostic, endoscopic procedure and results. Results: During the study period, 157 patients underwent endoscopic exploration and/or intervention. The mean age was 58.9 years (range 28 - 90 years). Males predominated with 95.5% (n = 150). Acute urinary retention was the most frequent reason for consultation (55.41%). Benign prostatic hyperplasia (BPH) was the most frequent pathology at 22.92% (n = 36). Urethrocystoscopy was performed in 52 cases (33.12%), Transurethral resection of the prostate (TURP) in 36 cases (22.92%), Endoscopic resection of secondary cervical sclerosis in 23 cases (14.64%), Endoscopic internal urethrotomy (EUI) in 15 cases (9.55%) and Transurethral resection of the bladder (TURB) in 10 cases (6.36%). Post-operative management was straightforward in 93.63% of cases (n = 147). Operative times of between 21 and 35 minutes were more frequent in 55.41% of cases (n = 87). Urinary tract infections accounted for 3.8% (n = 6) of surgical morbidity. The germ responsible for the infections was essentially Escherichia coli (E. coli). The mean duration of post-operative urinary drainage was 5.5 days (range: 4 - 6 days) for patients who underwent TURP, TURB and endoscopic resection of secondary sclerosis of the bladder neck. The mean duration of drainage after endoscopic internal ureterotomy was 21.6 days (range 14 - 30 days). Of the 157 endoscopies performed, 154 patients (98.08%) had a favourable outcome, with adenomyofibroma of the prostate being the most common histological type (52.17%, n = 36). Mortality was 1.27% (n = 2) in our series. Conclusion: Endo urology should be the urologist’s first choice for both exploration and surgery, given the satisfactory results.
文摘Introduction: Telemedicine has been used as a tool for improving access to health services worldwide. The aim of the present study is thus to evaluate the effectiveness of urological consultation by videoconference, perceptions regarding safety on the part of medical teams providing video consultation services and patient satisfaction after a urological appointment. Materials and Methods: A cross-sectional, observational, and analytical study was carried out with 50 volunteers referred from the basic health unit for a urology appointment. All patients were evaluated remotely by videoconference and in person by different urology teams. Results: The study revealed that effectiveness in terms of the degree of match between diagnoses performed by video consultation and those performed in person was 92%. The urology team’s perception regarding safety, measured using an in-house safety questionnaire, was high for both videoconferencing and in-person consultations and there was no statistical difference between the two (overall safety score for video consultation compared to in-person consultation was 9.7 ± 0.8 compared to 9.6 ± 0.8 and the p-value was 0.3 for Student’s t-test). Patient satisfaction with the appointment was similarly high for both groups, averaging 9.72 ± 0.4 among patients who attended a video consultation and 9.82 ± 0.4 among those whose consultation was conducted in person, with a p-value of 0.10478 for Student’s t-test. Conclusion: Video consultation in urology is an effective way to perform diagnoses, with high levels of perceived safety among urologists and high satisfaction rates among patients.
