Abstract：Objective:To investigate the efficacy and technical aspects of Allium ureteral stents in treating ure-teral strictures caused by radiotherapy for cervical cancer.Methods:29 cases of ureteral stenosis resulting from cervi-cal cancer radiotherapyadmitted to the Department of Urology at Jiangsu Geriatrics Hospital from October 2020 to March 2023 were retrospectively analysed.Intraoperative retrograde ureteral angiography combined with ureterosco-py revealed that the length of the strictures ranged from 6cm to 22cm,including unilateral stenosis in 13 cases and bi-lateral stenosis in 16 cases(55.2%),totaling 45 sides.Ureteroscopy combined with X-ray intervention was employed for dilating the ureteral strictures,followed by implantation of Allium ureteral stents for reshaping.Results:Success-ful completion of ureteral stricture dilation was achieved in all patients,with simultaneous bilateral placement of stents performed in five patients.Among these placements,there were fourteen sides(31.1%)where a twelve-centi-meter-long stent was used and thirty-one sides(68.9%)where a twenty-centimeter-long stent was utilized.Eight pa-tients(17.8%)experienced persistent dull pain on the implanted side of their abdomen during early stages;however,all symptoms disappeared within two months post-implantation.Three cases(10.3%)exhibited transient gross hema-turia while two cases(6.9%)developed febrile urinary tract infections;one case responded well to antibiotic treat-ment while another case required nephrostomy drainage after removal due to persistent reflux and severe infection.Conclusion:The combination approach involving ureteroscopy and X-ray guidance enables successful implementa-tion of Alliumureteral stents.It is recommended to preferentially employ twenty-centimeter-long ureteral stents as they effectively reduce the likelihood of restenosis following surgery.
