Transperitoneal laparoscopic dismembered pyeloplasty / 中华泌尿外科杂志

ABSTRACT

Objective To describe the new technique of transperitoneal laparoscopic dismembered pyeloplasty and to evaluate its clinical effect. Methods Of the 18 cases of ureteropelvic junction (UPJ) obstruction who underwent transperitoneal laparoscopic dismembered pyeloplasty,8 cases had severe hydronephrosis;7,intermediate;3,mild. Results Operations were all successful in 18 cases with the operating time being 100 to 210 min (mean,142 min) and the blood loss,40 to 200 ml.All the pores of puncture healed at phase 1;mean hospitalization was 7.4 d.Only 1 case had postoperative urine leakage.Follow-up of 3 to 12 months showed there was no stricture at UPJ and hydronephrosis was remitted (intermediate hydrops in 4 cases,mild in 7 and resolution in 7).The renal functions were improved. Conclusions Laparoscopic dismembered pyeloplasty is an effective and minimally invasive approach and can be used as an alternative to open surgery for UPJ obstruction.
