Rescue of renal transplants with distal ureteral complications by pyelo-pyelostomy.
Secondary ureteroneocystostomy is the procedure most commonly used for repair of ureteral stenosis or necrosis in renal transplant patients. However, when the transplant ureter available for reconstruction is too short, ureteropyelostomy is the standard procedure. Another option is pyelo-pyelostomy, which has been used infrequently to date. Between 1979 and 1988 we managed 6 patients (4 men and 2 women 42 to 62 years old) with renal allografts who required repair of the transplant ureter for long segmented ureteral necrosis (3), long segmented ureteral stenosis (2) and an iatrogenic lesion of the ureter (1) with pyelo-pyelostomy. Of the 6 patients 2 had undergone previous rescue operations. Pyelo-pyelostomy with the renal pelvis of the graft was performed as first described by Gil-Vernet and Caralps in 1968. Median followup was 6 years (range 3 to 12 years). Two patients died of chronic rejection and pulmonary embolism, respectively. Four patients are still alive with functioning transplants and serum creatinine levels of less than 210 mumol/l. According to our experiences with 6 patients, we believe that pyelo-pyelostomy is a promising rescue maneuver that is worth consideration in cases of total or subtotal ureteral necrosis and long segmented ureteral stenosis after renal transplantation.
