Feasibility analysis of balloon dilatation for primary obstructive megaureter
- Abstract:
- Objective To retrospectively review the postoperative follow-up data of balloon dilation for primary obstructive megaureter and explore its safety and feasibility.Methods From September 2018 to January 2022,preoperative and postoperative follow-up data were collected.The efficacy was statistically analyzed by compared the preoperative and postoperative data.Results 41 children with primary obstructive megaureter (42 ureters) undergoing balloon dilation,two cases of abdominal pain underwent laparoscopic ureteral reimplantation.One child failed to dilate,hydronephrosis remained stable and there was no further treatment.Another dilated case developed ureteral rupture and underwent ureteric reimplantation.A total of 37 children (38 ureters) were successfully operated.During regular follow-ups of (17.2±9.5) months,the mean age was (32.9±35.7) months and the mean preoperative renal function (48%±10%).Anteroposterior diameter (APD) of renal pelvis was (17.8±14.7) mm pre-operation and (9.7±8.9) mm post-operation (P<0.01).And the widest diameter of ureter was (13.4±2.9) mm pre-operation and (7.5±6.9) mm post-operation (P<0.01). Conclusion Short-term follow-ups after balloon dilatation show that upper urinary tract hydronephrosis is markedly relieved as compared with preoperatively.Balloon dilatation is a simple operation with a rapid recovery and broad application prospects
