Laparoscopic pyeloplasty and pyelopyelostomy for ureteropelvic junction obstruction in a duplicated collecting system.

Ureteropelvic junction obstruction can be associated with renal anomalies. We present a case of symptomatic ureteropelvic junction obstruction associated with a duplicated collecting system that was successfully treated by laparoscopic pyeloplasty and concomitant pyelopyelostomy. The operative time was 210 minutes, and the blood loss was 20 mL. The inpatient stay was 4.5 days, and the patient returned to work after 28 days. Subsequent renograms confirmed improvement in renal function and resolution of obstruction. After 1 year, the patient remained asymptomatic. This is a feasible minimally invasive procedure for this condition that requires advanced reconstructive and intracorporeal suturing skills.
