Objective: Radical prostatectomy is associated with complications including urinary incontinence. A significant association between specific features of the vesicourethral anastomosis and urinary incontinence after radical prostatectomy has been demonstrated. The aim of this study was to identify the most useful predictor of postoperative urinary incontinence after robot-assisted laparoscopic radical prostatectomy (RALP) according to the features of the vesicourethral anastomosis as determined by postoperative cystography. Materials and methods: The final study cohort consisted of 150 patients. Postoperative cystography was performed within 1 week after RALP. The ratio between the longitudinal and horizontal lengths (L/H) of the bladder, the position of the urethrovesical junction (UVJ) and the bladder neck angle as seen on the cystogram were evaluated. Postoperative continence status was evaluated by a 1 h pad test 1 day after catheter removal and by the use of safety pads, retrieved retrospectively from patient records. The association between these variables and urinary incontinence was then analyzed. All patients were followed for at least 1 year postoperatively. Results: The continence rates on the 1 h pad test and 1 month and 1 year after RALP were 31.3%, 56% and 93.3%, respectively. In multivariate analyses, urinary incontinence was significantly associated with nerve sparing, L/H and the vesical angle as determined on the 1 h pad test, but only with the vesical angle at 1 month and 1 year postoperatively. Conclusion: A narrow vesical angle measured on cystography is a useful predictor of postoperative urinary incontinence after RALP. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to evaluate the relationship between sexual activity and sexual function using questionnaires distributed to middle-aged Japanese patients with localized prostate cancer.Methods: A total of 145 patients who underwent radical prostatectomy were enrolled in the survey reported on herein. Sexual activity and sexual function were investigated via the Expanded Prostate Cancer Index Composite (EPIC) and an original self-reported questionnaire.Results: Of participants, 24.1% and 20.7% had sexual activity within a month period as investigated via the EPIC and original questionnaire, respectively. However, 29.7% of all those who reported sexual activity rate reported "about once every 2 months to a year," as shown in the original questionnaire. Regarding sexual function as addressed through EPIC, no results within that questionnaire's measure of sexual function showed significant differences among patients with a rate of actual sexual activity.Conclusions: The present survey showed that more than quarter of preoperative middle-aged Japanese prostate cancer patients surveyed had actual sexual activity, though not within the preceding 4 weeks. To precisely evaluate sexual function of middle-aged Japanese patients, it is necessary to consider actual sexual activity. [ABSTRACT FROM AUTHOR]

Purpose:Urinary biomarkers of renal injury urinary may identify loss of renal function following nephron-sparing surgery (NSS). This study was designed to evaluate whether urinaryl-type fatty acid-binding protein (l-FABP) is an early biomarker of loss of renal function after NSS. Specifically, the kinetics of urinaryl-FABP level after NSS and its correlation with factors related to ischemic renal injury were analyzed. Methods:This study prospectively evaluated 18 patients who underwent NSS between July and December 2014, including 12 who underwent laparoscopic and six who underwent robot-assisted partial nephrectomy. Urinaryl-FABP concentrations were measured preoperatively and 1, 2, 3, 6, 12, 24, 48, and 72 h after renal artery declamping. Loss of renal function loss was calculated by comparing the effective renal plasma flow, as determined by99mTc-mercaptoacetyltriglycine (MAG3) clearance, on the operated and normal sides. The decrease in estimated glomerular filtration rate from before surgery to six months after surgery was also measured. Results:Urinaryl-FABP concentration peaked within 2 h of declamping, which may quantify nephron damage caused by ischemia. The decrease in MAG3 reduction ratio correlated with both the ischemia time and peak urinaryl-FABP concentration. Peak urinaryl-FABP concentration showed a significant correlation with MAG3 reduction ratio. Conclusions:l-FABP is a suitable urinary biomarker for predicting the extent of ischemic renal injury.

Objective:The aim of this study was to evaluate and compare the cosmetic outcomes of laparoscopic single-site surgery (LESS) and conventional laparoscopy (CL) in the treatment of ureteropelvic junction obstruction (UPJO) and urachal remnant removal. LESS is thought to produce better cosmetic results than CL; however, patients’ perception of their scars has not been assessed. This study compared the subjective body image and cosmesis ratings of patients who had undergone LESS or CL for UPJO and urachal remnant removal. Materials and methods:Fifty patients who underwent LESS or CL for UPJO or urachal remnant removal between June 2008 and June 2015 were included. Cosmetic outcomes were evaluated using the Body Image Questionnaire (BIQ) and Photo-Series Questionnaire (PSQ). Results:The body image and cosmetic scores were significantly higher for patients who underwent LESS than for those who underwent CL, for both pyeloplasty and urachal remnant removal (p < .05 each). When performed for either a pyeloplasty or urachal remnant removal, significantly greater BIQ and PSQ scores were observed in females after LESS compared to CL, but not in males. Conclusion:LESS for UPJO and urachal remnant removal has better self-reported body image and cosmesis ratings than CL. This trend is particularly strong in female patients. [ABSTRACT FROM PUBLISHER]

We report herein a case of a patient with high-flow priapism for whom a gelatin sponge was used as a temporary occlusive agent in arterial embolization, resulting in favorable outcome. The American Urological Association guideline on the management of priapism recommends using temporary occlusive agents. We reviewed all reports published after the introduction of this guideline to compare temporary and permanent occlusive agents in terms of symptom improvement and onset of erectile dysfunction. The rate of symptom improvement differed significantly between temporary and permanent embolizing materials, but no significant difference was apparent in the rate of erectile function improvement.
