We retrospectively reviewed and compared the Trifecta and Pentafecta rates of the two robotic surgical platforms. Materials and Methods: A total of 338 patients who had undergone RAPN using da Vinci Si platform or Xi platform were included. Pentafecta was defined herein as Trifecta (a warm ischemia time <25 min, a negative surgical margin, and the absence of significant perioperative complications) with the addition of estimated glomerular filtration rate preservation of over 90% and no chronic kidney disease stage progression by 12 months postsurgery. Multivariate logistic regression analysis was conducted to identify the predictors of Trifecta and Pentafecta achievement. Results: The trifecta and pentafecta rates were higher in the Xi group than in the Si group (65% vs. 29%, P < 0.001 for trifecta; 31% vs. 14%, P = 0.001 for pentafecta). In addition, a significantly shorter average WIT (19 vs. 28 min, P < 0.001) and console time (141 vs. 163 min, P = 0.004) were identified in the Xi group than in the Si group. RAPN conducted using the Xi platform was independently associated with both higher achievement rates of trifecta and pentafecta. In addition, multivariate regression analyses revealed that no history of hypertension, low tumor complexity as measured using the RENAL nephrometry score, anterior orientation of the renal tumor were associated with higher Trifecta rates; while history of diabetes and anterior–posterior renal tumor orientation were the significant predictors of Pentafecta achievement, respectively. Conclusion: A significantly higher rates of trifecta and pentafecta achievement were observed in the Xi group than in the Si group. The use of the Xi platform was also significantly associated with low operative times and acceptable complication rates.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"34 1","pages":"99 - 106"},"PeriodicalIF":0.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48315393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated whether the combination of PHI and mpMRI better predict clinically significant PCa (csPCa), defined as a Gleason score of ≥7. Materials and Methods: Ninety-four men with clinical suspicion of csPCa were prospectively included. PHI was determined before the prostate biopsy. A uroradiologist reviewed mpMRI findings by using the Prostate Imaging Reporting and Data System version 2.1 (PI-RADS version 2.1). Fusion-targeted biopsy with systematic biopsy was performed in patients with any suspicious lesions on MRI (PI-RADS assessment category ≥3), whereas systematic biopsy was performed in patients without suspicious lesions. The diagnostic values of different biomarkers and PI-RADS were compared by the area under the receiver operating curve (area under the curve [AUC]) for detecting csPCa. Results: Forty-nine (52%) patients were diagnosed with csPCa. The csPCa group had higher median PHI and more abnormal MRI findings than did the non-csPCa group. The median total prostate-specific antigen (PSA) level was similar between the PI-RADS 3 and 4 lesion groups. The median PHI values increased and more patients were diagnosed as having csPCa with an increase in PI-RADS. The receiver operating characteristic curve indicated that PHI and MRI (AUC 0.85 and 0.82, respectively) predicted csPCa more accurately than did the total PSA, free PSA ratio, and PSA density. Adding PHI to mpMRI significantly increased the diagnostic accuracy for csPCa (P = 0.004). PHI remained the optimal biomarker in patients with “gray zone” PI-RADS 3 or PI-RADS 4 lesions. Conclusion: PHI can guide decision-making for prostate biopsy for patients with gray-zone mpMRI lesions. We proposed a biopsy strategy incorporating PHI and MRI which resulted in the avoidance of biopsies in 35% of the patients.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"34 1","pages":"86 - 92"},"PeriodicalIF":0.5,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42352255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we aimed to investigate the effects of single-session preoperative pelvic floor muscle training (PFMT) with biofeedback (BFB) on short- and mid-term postoperative UI and QoL. Materials and Methods: This study was performed between 2018 and 2020. The patients were randomized into two groups: the case group received a training session with BFB, supervised oral and written instructions on pelvic floor muscle exercises in a 1-h-long training session 1 month before the surgery. Patients were asked to regularly perform exercises immediately after the session until surgery. The controls received no instructions. We used the International Consultation on Incontinence Questionnaire-UI (ICIQ-UI) short-form and ICIQ-Lower Urinary Tract Symptoms QoL Module (ICIQ-LUTSqol) at 1, 3, and 6 months after removing the urinary catheter. Results: A total of 80 patients with a mean age of 63.83 ± 3.61 years were analyzed. Patient characteristics were similar between the groups. The mean ICIQ-UI score was significantly lower in the intervention group at 1 and 3 months after catheter removal (P = 0.01 and P = 0.029, respectively) but similar at 6 months (P = 0.058). The mean ICIQ-LUTSqol score was significantly lower in the intervention group at 1, 3, and 6 months after catheter removal (P < 0.001, P = 0.005, and P = 0.011, respectively). Conclusion: A single session of preoperative PFMT with BFB has significant short-term effects on UI after RP but not at 6 months.

Materials and Methods: From January 2020 to December 2020, 60 adult men diagnosed with as having phimosis and received circumcision were enrolled. Patients received either Holmium: YAG laser circumcision or conventional circumcision. In this study, we assessed the difference between the groups. Results: Although the operative time and blood loss decreased more in the Holmium: YAG laser circumcision group than in the conventional circumcision group (P < 0.001), a longer short-term delay in wound healing was observed in the laser circumcision group than in the conventional circumcision during the follow-up course (20.0% vs. 3.3%, P = 0.04). Our results also demonstrated no significant difference between the two groups in pain control, postoperative prepuce edema, prepuce redundancy, infection, or hematoma occurrence (P > 0.05). Microscopy findings of the resected prepuce in the Holmium: YAG laser circumcision group demonstrated a high percentage of coagulated small capillaries near the cutting edge. Conclusion: The holmium laser seems to be a concrete and feasible option for circumcision. Although patients undergoing holmium laser circumcision benefit from less blood loss and a rapid surgery compared to the conventional procedure, there is a higher risk of poor wound healing in short-term follow-up.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"34 1","pages":"28 - 32"},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41397652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: A single-center, retrospective review of the VUDS database on patients with NLUTD and chronic SCI from 1997 to 2020. A total of 507 patients were enrolled. All patients had a comprehensive chart review, including the injury level, period from diagnosis to VUDS, and VUDS characteristics. Results: The mean age and duration from SCI diagnosis to VUDS were 44.2 ± 15.7 years and 81.8 ± 89.0 months. Detrusor overactivity (DO) was observed in 67.7% of patients and detrusor underactivity (DU) in 26.0%. Bladder outlet obstruction was noted in 78.3% of patients, including detrusor sphincter dyssynergia (DSD) in 53.3% and bladder neck dysfunction in 25.0%. DO and DSD were more commonly observed in patients with suprasacral lesions (P = 0.000 and P = 0.000, respectively), whereas DU had a higher prevalence in patients with lumbar or sacral lesions (P = 0.000). No statistically significant difference was observed in the prevalence of vesicoureteral reflux among different SCI levels. Bladder sensation parameters were more preserved in patients with cervical SCI than in those with lumbar SCI; however, no significant difference in bladder compliance was observed among patients with different SCI levels. Conclusion: The VUDS in patients with SCI revealed a high prevalence of DO, DU, and DSD, which varied among different injury levels.

Materials and Methods: The USS PROM questionnaire used to evaluate lower urinary tract symptom (LUTS) was modified by adding a six-item International Index of Erectile Function and a four-item version of MSHQ-EjD to evaluate erectile and ejaculatory domains. All cases of short nontraumatic bulbar urethral stricture who underwent primary DVIU and NTBU who consented were asked to fill the modified PROM at initial evaluation, at 6 months, and at 1 year. Results: The LUTS score for NTBU at 12 months is significantly better (1.93 ± 2.13 vs. 8.76 ± 5.92, P = 0.000). The Peeling score of the NTBU is significantly better at 12 months (1.41 ± 0.68 vs. 2.67 ± 0.73, P = 0.000).

This article reports the current evidence and expert opinions on the patient-centered bladder management of neurogenic lower urinary tract dysfunction (NLUTD) among patients with chronic SCI in Taiwan. We evaluated the role of clean intermittent catheterization (CIC), cystostomy, medical treatment, and minimally invasive therapy for treating urinary incontinence and voiding dysfunction in patients with chronic SCI. The bladder management for chronic SCI patients should be individualized. A balance between upper urinary tract protection and life quality improvement should be considered. Hand dexterity, abdominal muscle power, bladder sensation, and degree of urethral sphincter dyssynergia might affect the improvement of voiding efficiency and NLUTD. Intradetrusor Botulinum Toxin Type A (BoNT-A) injection has been proven to effectively treat neurogenic detrusor overactivity in SCI patients. However, CIC is still required in some patients after treatment. The urethral sphincter BoNT-ABoNT-A injection can effectively relax the dyssynergic sphincter; however, exacerbation of urinary incontinence usually limits its application in SCI patients. Repeat BoNT-ABoNT-A injection is necessary to maintain the therapeutic efficacy; therefore, some SCI patients might discontinue the treatment and convert to a permanent bladder management by surgical intervention. Identification of high-risk SCI patients is important to prevent renal functional deterioration in those with chronic SCI-NLUTD. Avoiding renal function deterioration and improving the quality of life of SCI patients with NLUTD are the most important aspects of treatment. Annual active surveillance of bladder and renal function is necessary.","PeriodicalId":23449,"journal":{"name":"Urological Science","volume":"34 1","pages":"10 - 17"},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42458256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
