Renal calyceal neck atresia is a rare disorder. There is no clear guidance for standard treatment of this condition. The Memokath™ 045 temperature-controlled memory alloy stent is commonly used in the treatment of urethral strictures, but it has not been used for treating calyceal neck atresia. We present a case of a 44-year-old female patient with left lumbar pain who underwent two stages of treatment to resolve calyceal neck atresia located at the upper calyx of her left kidney. The first procedure was transurethral ureteroscopy combined with percutaneous recanalization of the left upper calyx calyceal neck atresia. One 6 F internal stent and one 8 F internal stent were placed, and she was discharged with a left nephrostomy tube. After her urinary tract infection was fully resolved, the patient returned for the second procedure of percutaneous upper renal calyx calyceal neck metal stent implantation. The temporary stents and nephrostomy tube were successfully removed. Our findings suggest that the Memokath™ 045 temperature-controlled memory alloy stent is an effective choice for treating calyceal neck atresia.

输尿管阴道瘘(UVF)是泌尿道生殖瘘的一种,对患者的生活质量造成一定的影响.目前,UVF的诊断不难,而且治疗方法多样,但近年来出现了新兴的治疗方法,为患者带来了更多的治疗选择.该文主要综述UVF及其治疗研究进展,旨在为临床提供参考.

输尿管阴道瘘是输尿管损伤后的一种严重并发症,大多数为妇产科手术造成[1,2] ,目前多采用输尿管镜植入双 J 管或开放手术修复输尿管阴道瘘治疗[3].留置双J 管瘘口自愈率低( 5％ ～15％) ,开放手术修复输尿管阴道瘘创伤大,患者难以接受[3].近年来,新型覆膜金属支架已应用在输尿管狭窄的治疗中,这类支架具有覆膜结构以及自膨胀金属局段支撑的特点[4～6].2018年11月～2019年6月我们对6例妇科手术致输尿管阴道瘘采用新型覆膜金属支架( Allium Medical)治疗,现报道如下.
