Laparoscopic pyeloplasty.

Thirteen patients underwent laparoscopic dismembered pyeloplasty at our institution. The operative time ranged from 4 to 8 (mean 5.4) hours with minimal blood loss. Two patients developed transient edema necessitating temporary drainage. The mean requirement for morphine postoperatively was 32 mg. At a mean follow-up of 13 months, all patients demonstrated both symptomatic and radiographic relief of obstruction. Laparoscopic dismembered pyeloplasty appears to be an effective minimally invasive alternative to treat symptomatic ureteropelvic junction obstruction.
