[Urinary diversions and intestinal grafts in renal transplantation in children. Report of 8 cases].
In a series of 400 transplantations, 8 children presented a severe lesion of the lower urinary tract requiring an intestinal graft to divert the urine or to replace the useless bladder: 4 cases of posterior urethral valves and 4 cases of neurogenic bladder. Four permanent urinary diversions and 4 bladder enlargements, including 3 temporary diversions, were performed. The sigmoid colon was used in 5 cases and the ileum was used in 3 cases. The preparation of the intestinal graft was always performed prior to the transplantation. The uretero-intestinal anastomosis included an antireflux device in 3 of the 8 cases. There were no deaths in this series. Three occlusions and 2 lymphoceles occurred in the immediate post-transplantation period, but were corrected by re-operation. Two cases of calculi occurred in the long term, one of which required operation. Moderate stenosis of the renal artery in one case resulted in systemic hypertension which was well controlled by medical treatment. An episode of acute pyelonephritis resolved rapidly with antibiotic treatment. Two cases of acidosis were corrected by salt supplementation. There was one case of early graft rejection on the 15th day and a delayed rejection after 18 months, leading to removal of the transplant. At the present time, 6 renal grafts function normally (75%) with a follow-up of 1 to 8 years.
