In 4 patients with cutaneous urinary diversion who underwent percutaneous ureteral stone removal, similar ureteral complications developed as a result of severe ureteritis at the site of the stone. Ureteral narrowing occurred within days of percutaneous ureteral stone removal, progressing to complete occlusion in 2 cases. These complications led to prolonged hospitalization and additional procedures for each patient. One patient with an occluded ureter was lost to followup. Two patients responded satisfactorily to repeated ureteral dilations and prolonged stenting. One patient underwent excision of the affected ureteral segment. The average interval between tube placement and removal of tubes and stents was 15 weeks in 4 patients. The average inpatient period was 24 days. Patients with a cutaneous urinary conduit diversion may be at increased risk for complications following percutaneous treatment of ureteral stones. This risk may be secondary to an intense inflammatory response due to infection and other local factors.
在4例接受经皮输尿管取石术的皮肤造口尿液转流患者中，由于结石部位严重的输尿管炎，出现了类似的输尿管并发症。输尿管狭窄在经皮输尿管取石术后数天内发生，2例进展为完全梗阻。这些并发症导致每位患者住院时间延长并需要额外的手术。1例输尿管梗阻患者失访。2例患者对反复输尿管扩张和长期置管反应良好。1例患者接受了受累输尿管段切除术。4例患者置管与拔管及支架的平均间隔时间为15周。平均住院时间为24天。皮肤造口尿液转流的患者在经皮治疗输尿管结石后可能发生并发症的风险增加。这种风险可能继发于感染和其他局部因素引起的强烈炎症反应。
