Clinical and urodynamic assessment of the porcine dermis bladder sling in the treatment of genuine stress incontinence.

Fifty women, aged between 37 and 76 years, underwent a bladder sling operation for urinary incontinence using porcine dermis. All patients had undergone previous unsuccessful vaginal surgery for genuine stress incontinence and had stable bladders. Thirty-nine patients (78%) were made continent of urine, both subjectively and on urodynamic testing.
