Renal transplantation in children with obstructive uropathy.

The outcome of renal transplantation was examined in 52 pediatric patients (mean age 13 years) whose primary renal disease was obstructive uropathy. The bladder was used at transplantation in 45 allograft recipients, 39 of whom had had a previous lower urinary tract operation or bladder defunctionalization. An ileal loop was used in 7 recipients. The 52 patients received 73 renal allografts from 58 cadaver and 15 live-related donors. Presently, 40 patients (77 per cent) have functioning allografts, 4 have returned to dialysis and 8 (15 per cent) have died. The results indicate that the outcome of renal transplantation in patients with obstructive uropathy is similar to that of other transplant recipients. Damaged and defunctionalized bladders may be used successfully in most cases. If necessary an ileal conduit is an effective alternative. Post-transplant urologic complications occur with increased frequency but with appropriate management allograft salvage and patient survival are excellent.
