[Transureteroureteroanastomosis in children. Indications and results]

Transureteroureterostomy is a method of internal urinary diversion available to maintain the integrity of the urinary system, when the lower ureter is compromised. The usual requirements are a donor kidney with a minimal renal function on one side and a normal contralateral recipient kidney and ureter. From January 1972 to October 1988 in our Division transureteroureterostomy has been done in 52 children. In some cases the procedure was used simultaneously with reimplantation or cutaneous ureterostomy. The majority of patients had been referred with previous failed ureteral reimplantation or with unilateral reflux or ureteral obstruction in neurogenic bladder with small capacity and compliance. Results (14 years to 6 months follow-up) are very good with excellent results for both kidneys in 98% of the cases. Our experience and that of other authors confirm that transureteroureterostomy is a technique simple with low morbidity and excellent results.
