Autologous renal transplantation with direct pyelocystostomy in the treatment of recurrent renal calculi.

Six male patients with severe recurrent urinary calculus disease underwent renal autotransplantation with direct pyelocystostomy to allow spontaneous passage of stones. The only serious complication was an early renal vascular thrombosis with graft loss in one patient who had been operated on three times before with ipsilateral partial resections for nephrolithiasis. The other five patients did well (observation time 4-34 months). Their renal function has remained unchanged. Autotransplantation with direct pyelocystostomy should be considered in patients with multiple recurrent stones of the upper urinary tract, especially when some degree of obstruction has developed or when other predisposing anomalies prevail.
