Laparoscopic treatment of ureteropelvic junction obstruction / 中国微创外科杂志

ABSTRACT

Objective To evaluate the clinical efficiency of laparoscopic operation for the treatment of ureteropelvic junction obstruction(UPJO).Methods A total of 19 patients with UPJO underwent laparoscopic dismembered pyeloplasty.The operation was performed under general anesthesia.The patients were maintained in a lateral decubitus on unaffected side.After the establishment of pneumoperitoneum,3~4 trocars were introduced at proper sites.During the operation,the lateral peritoneum was opened and the ureteropelvic junction obstruction was dissociated and dissected.The end-to-end anastomosis of the renal pelvis and ureter was conducted and a double-J stent was placed in the ureter.Results All the operations were performed successfully.The operation time was 110~240 min(mean,150 min),the blood loss was 50~100 ml(mean,80 ml),and the postoperative hospitalization time,6~10 d(mean,7.8 d).No severe complications occurred.Follow-up assessment with intravenous urography for 3~15 months(mean,6 months) in 14 patients showed no ureteral stricture.Conclusions Laparoscopic dismembered pyeloplasty is an effective and safe procedure in the treatment of UPJO.It can replace the open surgery.
