Laparoscopically assisted dismembered pyeloplasty without the V-flap reconstruction: Report of 13 cases / 中国微创外科杂志

ABSTRACT

Objective To evaluate the feasibility of laparoscopically assisted dismembered pyeloplasty without the V-flap reconstruction.Methods A total of 13 cases of ureteropelvic junction obstruction(UPJO) underwent laparoscopically assisted dismembered pyelopasty via a small incision through the retroperitoneal approach without the V-flap pyeloplasty technique.After exposing the proximal ureter and renal pelvis to identify the UPJ obstruction,the UPJ area is then excised and the apex of the ureter is then anastomosed to the most inferior aspect of the renal pelvis. Results All the operations had been successfully completed.The operating time was 100~180 min(mean,121 min),and the intraoperative blood loss,30~100 ml(mean,70 ml).Follow-up for 3~20 months(mean,12.3 months) in 12 cases revealed a full recovery of renal functions and disappearance of hydronephrosis.Conclusions Laparoscopically assisted dismembered pyeloplasty without the V-flap reconstruction is feasible in the treatment of UPJO.
