Ureteral obstruction is a commonly encountered condition during daily practice. The mainstay of treatment for ureteral obstruction is drainage and relief of the obstruction, regardless of the etiology. Drainage using the traditional ureteral Double J stent has been recently challenged with new ureteric stent that proposed to have better durability and patient quality of life, particularly in cases that require prolonged insertion. One of these options are the ureteric metallic stents, such as Memokath, although uncommon, encrustation of Memkath can occur, leading to early removal. Here we present a case of 28-year-old gentleman with recurrent right pelviureteric junction obstruction, who had undergone pyeloplasty in childhood, The patient was hesitant to undergo redo pyeloplasty and opted for balloon dilatation with Memokath insertion. however early encrustation occurred leading to worsening of the condition and pain, and he was subsequently managed with robotic assisted laparoscopic Memokath extraction and dismembered pyeloplasty.
输尿管梗阻是日常临床实践中常见的病症。无论病因如何，输尿管梗阻的主要治疗方法是引流和解除梗阻。传统的输尿管双J支架引流最近受到了新型输尿管支架的挑战，新型输尿管支架被认为具有更好的耐用性和患者生活质量，特别是在需要长期置入的情况下。其中一种选择是输尿管金属支架，如Memokath，尽管不常见，但Memokath可能会发生结垢，导致早期取出。在此，我们报告一例28岁男性复发性右肾盂输尿管连接部梗阻病例，该患者童年时曾接受肾盂成形术。患者对再次进行肾盂成形术犹豫不决，选择了球囊扩张并置入Memokath。然而，早期结垢发生，导致病情恶化和疼痛，随后他接受了机器人辅助腹腔镜Memokath取出术和肾盂成形术。
