First of all, it should be clear that there is no absolutely safe surgical treatment, only relatively safe. Ureteral stenosis has different possible intraoperative as well as postoperative complications according to different surgical methods.
1. Ureteral dilatation: For example, balloon dilatation may damage the ureteral muscularis layer during surgery, which may lead to postoperative over-dilatation of the ureter and the development of ureteral pseudocysts.
2. Ureteral stenting may result in postoperative ureteral stent dislodgement and restenosis due to the placement of the stent, as well as the material of the stent and individual differences.
3. Ureteral reconstruction surgery is an open surgery, which may result in postoperative or intraoperative infections due to improper aseptic operation or postoperative immunocompromise.
In conclusion, any kind of surgery may have complications or risks, there is no absolutely safe surgery, it is recommended to go to a professional hospital in time and listen to the doctor’s advice according to your own situation.
