Objective

The aim was to investigate bladder neck (BN) and tape mobility and correlate this with the efficacy of the transobturator tension free sling (TOT) in treating stress urinary incontinence.

Methods

Perineal ultrasound was performed at rest and during Valsalva and the movement of the BN, tape, and urethral positions were documented. Vectorlength of the BN and tape were calculated at rest and during Valsalva, as was the α-angle (urethral angulation by the tape during Valsalva) postoperatively. Objective cure for urinary stress incontinence was determined by a negative cough stress test (CST done sitting with 250 mL in the bladder).

Results

One hundred and twenty-three of 137 women (90%)(age 51.3, range 29–86; parity 3.1, range 1–6) had negative CST with mean follow-up of 12.9 months (range 3–21). The BN vector length at rest and Valsalva preoperatively and postoperatively of 10.4 and 8.3 mm were …
