Abstract

The use of diversion in conjunction with pyeloplasty has been a matter of continuous debate for a number of years. A retrospective analysis of 20 cases with ureteropelvic junction obstruction which had pyeloplasty with or without diversion was done to evaluate the value of urinary diversion. The postoperative symptomatic and radiologic results were improved in 9(75%) of 12 patients with nephrostomy catheter and/or ureteral stent and in 7(87.5%) of 8 patients without nephrostomy catheter and ureteral stent (p>0.05). One patient with ureteral stent developed persistent hemorrhage and persistent urine leakage occurred in one patient with nephrostomy catheter and ureteral stent and one patient without diversion. In conclusion, nephrostomy catheter and ureteral stent appear to be unnecessary in the routine repair of primary uncomplicated ureteropelvic junction obstruction, if urologist strictly adhered to technical details.
