A study of 100 patients has shown that stenting of the ureteropelvic anastomosis after laparoscopic or robot-assisted pyeloplasty for 1 week is as effective as for 4 weeks (100% and 98% success rates, respectively). Postoperative follow-up assessment was performed at 3 months with an IVU, at 6 months with diuretic renography, and at 1 year, 3 years, and 5 years with ultrasonography. No significant differences were reported in residual symptoms, complication rates, and renal function, but duration of hospitalization was shorter in the 1-week group.
