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.
肾盂盏颈口闭锁是一种罕见的疾病。目前对于这种疾病的标准治疗方法没有明确的指导。Memokath™ 045 温控记忆合金支架常用于治疗尿道狭窄，但尚未用于治疗肾盂盏颈口闭锁。我们报告了 1 例 44 岁女性患者，因左侧腰痛就诊，该患者接受了 2 个阶段的治疗以解决位于其左肾结石上盏的肾盂盏颈口闭锁。第一阶段的治疗是经尿道输尿管镜联合经皮左肾结石上盏肾盂盏颈口闭锁再通术，留置了 1 根 6F 内支架和 1 根 8F 内支架，并留置左肾造瘘管出院。患者的尿路感染完全治愈后，行第 2 阶段经皮肾盂上盏肾盂盏颈口金属支架植入术。临时支架和肾造瘘管成功取出。我们的研究结果表明，Memokath™ 045 温控记忆合金支架是治疗肾盂盏颈口闭锁的有效选择。
