A Comparative Analysis Of Balloon Dilatation And Laparoscopy In The Treatment Of Iatrogenic Ureteral Stricture

Objective:To compare the curative effect,advantage and disadvantage of balloon dilatation and laparoscopic surgery to treat iatrogenic ureteral stricture.Method:49 patients with iatrogenic ureteral stricture has been chosen to be in retrospect.These patients were from our department from July 2015 to April 2017,among which27 patients were with balloon dilation and 22 with laparoscopic surgeries.Both groups were treated with iatrogenic ureteral stricture,which had been confirmed before operation,and the stenosis length was no more than 1cm,and the renal GFR was less than 10ml/min.The patients were divided into two groups,one is balloon dilatation group(27 cases)and the other is laparoscopic group(22 cases).Evaluation of efficacy by compareing two groups of perioperative data.The data was analyzed by using SPSS19.0.Result:Without the side effects of surgical treatment,all of the 49 patients in this study were successfully operated under general anesthesia.As to the length of operation time,the balloon dilation group was 53.85±18.67(min),and the laparoscopic group was 152.50±39.75(min).In terms of the amount of bleeding,the balloon dilatation group was 12.67±4.89(ml),and the laparoscope group was 152.64±15.03(ml).As to the average time of staying in hospital after surgery,the balloon dilation group was3.96±1.09(day),and the laparoscopic group was 7.0±1.41(day).For the p above is less than 0.001,the data obviously has significant statistical value.Three months after surgery,the effective rate of balloon dilatation group was 92.59%,the rate of the laparoscopic group was 95.45%.Six months later,the effective rate of balloon dilatation was 70.37% and laparoscopic group 90.91%.One year later,the effective rate of balloon dilatation group was 55.56%,and the other 90.91%.P from three months and six months were both bigger than 0.05,so it has no statistical value,but p after 12 months was smaller than 0.05,which was in value.Conclusion:For patients whose iatrogenic ureteral stricture is less than 1 cm,laparoscopic surgery has a higher successful rate than balloon dilatation in long term.But considering that the balloon dilatation is more minimally invasive,more simple and easier to perform,and with high repeatability,even more safe after the urethral retrograde balloon dilatation,therefore it can be used as a treatment option.
