title: A preliminary clinical study of endoscopic minimally-invasive surgery in urethral stricture complicated with false passage.
abstract: The aim of this study was to explore the clinical effect of endoscopic minimal invasive surgery on posterior urethral stricture with false passage. Twenty-one patients suffering from posterior urethral stricture with false passage were involved in the study. All the patients received pre-operative urethrography and flexible cystoscopy to make sure that the distance between the blind end of the proximal normal urethra and the distal urethra was <1 cm. Ten patients received open operation and eleven patients underwent endoscopic minimally-invasive surgery. All the patients in both groups had their catheters removed 4 weeks after operations, and improvements in urination and incontinence were observed. Urethrography was performed and urine flow rate was measured 1 month after catheter removal. In the open-operation group, nine patients showed unobstructed urinary tracts in the urethrography, and one, after his catheter removal, experienced dysuresia, which was improved after urethral dilatation. In the minimally-invasive operation group, nine patients showed patent urinary tracts in the urethrography, and two experienced post-operation dysuresia, of whom, open-operation treatment and urethral dilatation were performed respectively. In the minimally-invasive operation group, the average urine flow rate was significantly increased. Patients in both groups obtained obvious improvement in post-operation urinary incontinence, and there was no statistically significant difference between the two groups in urine flow rate and index for urinary incontinence. Endoscopic minimally-invasive operation had similar effects to open operation in treatment of posterior urethra stricture with <1 cm in length and false passage.
