Incisional bladder hernia and urinary incontinence: report of three cases.

Herniation of the bladder has been primarily described in association with inguinal and femoral hernias. Review of the literature yielded only one case report of incisional bladder hernia. The authors report three cases of herniation of the bladder through a postoperative fascial defect. All patients presented with nonspecific sensory lower urinary tract symptoms, pelvic discomfort, and urinary incontinence. Involuntary urine loss as related to bladder hernia has been mentioned only circumstantially. Although urodynamic evaluations were performed, the mechanism of urinary incontinence could not be clarified. Cystography was essential in arriving at a definitive diagnosis.
