Abstract
Twenty women with urodynamically proven genuine stress incontinence were randomly allocated to treatment by suburethral sling or Stamey endoscopic bladder neck suspension. Urodynamic assessment was performed before and 3 months after surgery; clinical follow-up is reported up to 2 years. Blood loss was greater, and there were significantly more postoperative complications associated with the sling procedures. The subjective and objective cure rates at 3 months and 2 years were not significantly different between the two procedures. No significant changes in the resting urethral pressure profile were evident, although with both procedures, cure was associated with an enhancement in pressure transmission ratios in the proximal urethra. Detrusor instability occurring for the first time after operation was associated with both procedures; the sling, in addition, induced a significant degree of outflow obstruction, although this was not evident after the Stamey procedure.
