摘要宫颈癌放疗后的输尿管狭窄和膀胱挛缩是泌尿外科的难题。回肠输尿管成形联合回肠膀胱扩大术是改善患者肾积水和排尿功能的潜在方法，然而该手术过程较为复杂，手术风险大，术中、术后并发症较多，影响了该术式的推广应用。本中心采用回肠代双侧输尿管联合回肠"N"形膀胱扩大成形术治疗1例。术后2周拔除单J管，术后3周拔除导尿管，患者自主控尿，排尿通畅。术后3、18个月随访，双侧输尿管无积水，肾功能正常，膀胱容量明显扩大。

abstractsUreteral stenosis and bladder contracture after radiotherapy for cervical cancer are challenging issues in urology. Ileal ureteroplasty combined with ileal bladder augmentation is a potential method to improve hydronephrosis and voiding function of patients, however, the surgical procedure is complex, with high surgical risks and numerous intraoperative and postoperative complications, which have hindered the widespread application of this surgical technique. This article introduces our hospital's experience through a typical surgical case. During the surgery, ileal substitution for bilateral ureters was performed in combination with ileal " N-shaped" augmentation. Two weeks after the surgery, the single-J stent was removed, and the urinary catheter was removed three weeks after the surgery. The patient achieved voluntary urination control with smooth voiding. Follow-up examinations at 3 months and 18 months postoperatively showed no hydronephrosis in the bilateral ureters, normal renal function, and a significantly expanded bladder capacity.
