Ventral bladder hernia following Marshall-Marchetti-Krantz procedure for stress urinary incontinence

Ventral herniation of the bladder occurred in 2 patients following Marshall-Marchetti-Krantz procedures for stress incontinence. Symptoms included suprapubic pain, urgency, incontinence, and a ventral abdominal hernia. The diagnosis was easily established by cystography in both patients. Possible etiologic factors included postoperative wound infection in 1 patient and possibly suspension of the anterior bladder to the pubis in the other.
