Application of indwelling renal pelvis drainage and ureteral stent in laparoscopic pyeloplasty / 中华实用儿科临床杂志

ABSTRACT

Objective To assess the feasibility and efficacy of renal pelvis drainage and ureteral stent of laparoscopic pyeloplasty in treatment of ureteropelvic junction obstruction.Methods Eighteen patients(14 boys and 4girls) with ureteropelvic junction obstruction,the average patient age was 66 months (range 3-182 months),who underwent transabdominal laparoscopic Anderson-Hynes pyeloplasty in Capital Institute of Pediatrics from Aug.2011 to Oct.2012 were selected.The ureteral stent and renal pelvis drainage were installed during the performance of surgery.They were removed in 7 days and 9 days after operation respectively.Results Eighteen cases successfully underwent laparoscopic pyeloplasty,without conversion to open surgery.The mean operating time was 102.8 minutes (ranging between 90 and 150 minutes).Two cases had complications on postoperative day 3,one patients ureteral stent was inadver-tentely pulled out,another was removed because of blood clots.No patient had postoperative urinary leakage or anastomotic stenosis.Postoperative follow-up time was 6 months.The hydronephrosis vanished in 13 patients,reduced obvious ly in 5 patients as revealed by ultrasound examination.Conclusions Intraoperatively,renal pelvis drainage and ureteral stent for postoperative drainage is effective,and it is worthy of application in a large scale.Patients can avoid further anesthesia for removing stents and the complications of long-term indwelling stent tubes,and have an improved quality of life.
