Stamey endoscopic vesical neck suspension in female urinary stress incontinence: results and changes in various...

A total of 32 female patients with urinary stress incontinence who underwent a Stamey endoscopic bladder neck suspension were clinically and urodynamically studied pre- and postoperatively. Complete cure was obtained in 78% of the patients and improvement in 6%, the overall success rate being 84% for a mean follow-up of 11.1 months (range 6-19). Complications occurred in 22% of the patients. Comparison of the pre- and postoperative urodynamic data revealed that the maximum urine flow rate, functional urethral length and maximum urethral closure pressure were changed significantly after operation. In addition, when studying the abdominal pressure transmission to the entire urethra during stress, there was a significant conversion of negative to positive pressure transmission after surgical repositioning of the urethra.
