MARTINEZ DEL CASTILLO, M.L. et al. Spontaneous urinary bladder perforation after pediatric cystoplasty. Actas Urol Esp [online]. 2005, vol.29, n.9, pp.869-878. ISSN 0210-4806.

Objective: The spontaneous cystoplasty perforation is a serious and potentially fatal problem if a delay in diagnosis and treatment occurs. We pretend: 1) to look for prevention analyzing the risk factors, 2) to identify the main data of diagnostic suspicion and 3) to evaluate the result of the treatments done. Material and Methods: Out of 30 children with cystoplasty 5 of them have presented 8 perforations (16,6%). Several influential factors, the symptoms, the treatments and the evolution are reviewed. Results: The average time between cystoplasty and the perforation was 8,2 years. A urethral resistance that allows continence, and an insufficient intermittent catheterization, have been the main risk factors. In the 8 episodes there were abdominal pain and distension. The ultrasonography showed intraperitoneal extravasation in 5 episodes, multiple peritoneal cysts in one, and suggestive image of appendicular plastron in another one. The cystography showed intraperitoneal extravasation only in 3 cases. The initial management was conservative in the 7 episodes diagnosed before surgery, and 3 had a good evolution (42,8%); the other 4 needed surgery with good evolution in all cases. Two of 5 patients (40%) presented 3 relapses in an average time of 5 years. The survival is 100%. Conclusions: 16,6% of patients with cystoplasty of this series had one or more episodes of spontaneous bladder perforation. The more significant risk factors are a high urethral resistance and an inadequate intermittent catheterization. The patients with cystoplasty, and their families, must know this complication, their risk factors and symptoms to prevent it, or to facilitate an early diagnosis.
