Vesicoureteric reflux following renal transplantation: a simple method of ureteric implantation.

We have used a simple method of ureteroneocystostomy in renal transplant patients. This entails a no-tunnel "drop-in" with a long free segment protruding into the bladder lumen. The incidence of vesicoureteric reflux was investigated in 81 transplant patients who had a follow-up period ranging from 4 months to 15 years (mean 3.7 years); 29 of these patients had recurrent urinary tract infections. Micturating cystography demonstrated reflux in 6 patients (7.4%). In these 6 patients the presence of reflux had no deleterious effect on renal function and the infections were easily controlled with long-term antibiotics. In the 52 patients without injury infection no reflux was demonstrated. The conclusions based on this study indicate that (1) in the absence of recurrent infection there are no indications for micturating cystography and (2) this method of ureteroneocystostomy is expedient and has a low incidence of reflux.
