ABSTRACT

Objective To describe the retroperitoneal laparoscopy-assisted Anderson-Hynes dismembered pyeloplasty with small incision for the treatment of ureteropelvic junction obstruction (UPJO) and to evaluate its clinical effect. Methods Twelve cases of UPJO (8 men and 4 women;age range,5-48 years) underwent retroperitoneal laparoscopy-assisted, small incision,dismembered pyeloplasty.Of them,4 cases had severe hydronephrosis;6,intermediate;and 2,mild by B-ultrasound and urography.Nine cases had good IVU imaging and 3 had poor IVU imaging. Results All the procedures were successful.The operative time was 100-180 min (mean,127 min);the blood loss was 30-100 ml(mean,70 ml) and the postoperative hospitalization was 5-8 d (mean,5.6 d).No perioperative complication occurred.Follow-up of 3-12 months by intravenous urography and B-ultrasound showed no stricture at UPJ,and hydronephrosis was remitted and renal functions were improved. Conclusions Retroperitoneal laparoscopy-assisted Anderson-Hynes dismembered pyeloplasty with small incision is a feasible,minimally invasive and effective way to treat UPJO with less morbidity and shorter convalescence.
