Urethral hypermobility after anti-incontinence surgery - a prognostic indicator?

The aim of this study was to define the concept of hypermobility of the bladder neck and determine its effects on the cure rate and postoperative complications in patients undergoing colposuspension. In a retrospective study, 310 patients who underwent primary colposuspension for urodynamically proven genuine stress urinary incontinence were assessed by introital ultrasound before surgery and during follow-up for up to 48 months postoperatively. A total of 152 women completed 48 months of follow-up. Mobility of the bladder neck during straining was described as linear dorsocaudal movement (LDM) with LDM >15 mm being defined as hypermobility. The overall objective cure rate was 90.0% at 6-month follow-up vs 76.8% at 48-month follow-up (Kaplan-Meier estimators). Urge symptoms occurred in 12.6% (39/310) of the women and de novo urge incontinence in 2.3% (7/310). Bladder neck hypermobility was significantly reduced after anti-incontinence surgery, from 67.1% (208/310) before surgery to 5.5% (17/310) immediately after surgery (P<0.0001). Postoperative hypermobility was associated with a higher recurrence rate. In the hypermobility group, 52.9 and 34.0% of the patients were continent for up to 6 and 48 months, respectively, as opposed to 92.2 and 79.2% in the group without hypermobility (P<0.0001). Women with postoperative hypermobility had a 3.2-fold higher risk of recurrence within 48 months. Bladder neck hypermobility after surgery was also associated with postoperative voiding difficulty (P=0.0278). Patients in whom hypermobility of the bladder neck diagnosed before surgery persists after colposuspension have a higher risk of recurrence and are more likely to develop postoperative complications than those without this hypermobility.
