Background: Spontaneous bladder rupture is a known complication of augmentation cystoplasty. We report the second case of bladder rupture during filling cystometry many years after bladder augmentation and the first case occurring in a patient with an autoaugmentation cystoplasty. In addition, the management and outcome for a bladder perforation in an autoaugmentation cystoplasty will be discussed.
Case: A 20-year-old male with a history of an L4 myelomeningocele underwent an autoaugmentation cystoplasty for neurogenic bladder dysfunction and decreased bladder wall compliance five years previously. He self catheterized four times daily. During filling cystometry, detrusor pressure increased to 60 cm H2O with 300 mL filling. Detrusor pressure then rapidly decreased to 20 cm H2O without evidence of external leakage. The infusion was immediately stopped and X-ray showed intraperitoneal leakage of contrast material. Serial abdominal examination demonstrated worsening abdominal distension. Exploratory laparotomy revealed a 2 cm perforation within the autoaugment portion of the bladder.
Conclusion: An autoaugmentation cystoplasty improves bladder compliance and capacity with the use of native urothelial tissue. Although perforation after autoaugmentation has not been previously reported, caution must be used during urodynamic evaluation in patients with decreased bladder wall compliance and augmentation cystoplasty.
