Laparoscopic technique combined with open surgical technique in pyeloplasty(report of 45 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To assess the laparoscopic technique combined with open surgical technique in pyeloplasty.Methods Overall,45 patients with ureteropelvic junction obstruction underwent laparo- scopic dissection of the renal pelvis and upper ureter transperitoneally,and pyeloplasty was performed through a expanded trocar-incision(extension of 1-2 cm)as open surgery was performed.Results The opera- tion was successful in all 45 patients.The mean operative time was 58 min(range,40-85 min),and the mean blood loss was 22 ml(range,15-30 ml).No complication was observed during and after operation. Follow-up for 3-36 months was available in 34 patients.Intravenous urography(IVU)showed no obstruc- tion of the anastomotic stoma,and B-ultrasound indicated relief of hydronephrosis.Conclusions Laparo- scopic approach combined with open surgery in pyeloplasty is an effective way to treat ureteropelvic junction obstruction.This technique can simplify the operative manipulation and shorten the operative time without more trauma to the patients.It is worth general application in clinical practice.
