- Abstract: Objective To explore the immediate recanalization efficacy of flexible endoscopy-assisted retrograde ureteral catheterization for uretero-ileal anastomotic stenosis after Bricker ileal bladder surgery.Method A retrospective analysis was conducted on the clinical data of 17 patients who underwent Bricker ileal bladder surgery in the hospital from November 2016 to October 2022.There were a total of 28 sites of ureterileal anastomotic stenosises,all of which were treated with flexible endoscopy-assisted retrograde ureteral catheterization.Result There were 21 sites who successfully underwent recanalization after endoscopic treatment,the median length of hospital stay was 6(4.75,8.50)days.Among the 28 uretero-ileal anastomotic stenosises,21 sites were successfully recanalized immediately under endoscopy(10 on the left and 11 on the right),while 7 sites failed to recanalize immediately under endoscopy(4 on the left and 3 on the right).The 21 sites of successful immediate recanalization under endoscopy include:15 sites of simple retrograde placement of ureteral catheters,1 site of endoscopic ureterileal anastomotic dilation,net basket stone removal and retrograde stent placement,3 sites of retrograde ureteral stent placement under ultra-fine endoscopy,and 2 sites of retrograde ureteral stent placement under duodenoscopy.The total operation time of all patients was less than 50 minutes.Among the 17 patients,the urine drainage of the ureteral stent was unobstructed.There were varying degrees of abrasions and a small amount of bleeding at the bladder ileal and ureterileal anastomoses.No serious complications such as delayed bleeding,perforation,severe urinary tract infection,stent blockage or displacement occurred.Conclusion Flexible endoscopy-assisted retrograde ureteral catheterization are safe and effective for immediate recanalization of uretero-ileal anastomotic stenosis.It is worth applying in clinical practice.
