Urodynamic evaluation after endoscopic modified bladder neck suspension.

A total of 45 simplified double-needle bladder neck suspensions for genuine stress incontinence were clinically and urodynamically evaluated pre- and postoperatively. After a mean follow-up of 26 months, the subjective cure rate was 82.2% and the objective cure rate was 86.6%. Comparison of the pre- and postoperative urodynamic parameters showed a significant change in the maximum urethral closure pressure, functional urethral length, bladder capacity and maximum urine flow rate but no significant alteration in maximum detrusor pressure and first sensation during bladder filling. In summary, the modified bladder neck suspension effectively restores normal urethral function urodynamically.
