A 38-year-old woman with a duplicated right collecting system and a history of right upper-pole heminephrectomy was referred for persistent dysuria and right lower-quadrant abdominal discomfort. Imaging identified a remnant ureter and a ureterocele filled with what appeared to be a large homogenous stone. At cystoscopy, the ureterocele was incised with a holmium:YAG laser, releasing a large quantity of white milky fluid (milk of calcium). There was no evidence of any solid material. Endoscopic evaluation should be the first step in patients with stones in a ureteral stump because milk of calcium may be the etiology of what appears to be a large stone burden in an obstructed system.
一名38岁女性，有右侧重复集合系统及右上极半肾切除术史，因持续性排尿困难和右下腹不适前来就诊。影像学检查发现一条残余输尿管及一个输尿管囊肿，囊肿内似乎充满了一块巨大的均质结石。膀胱镜检查时，用钬激光切开输尿管囊肿，流出大量白色乳状液（钙乳）。未发现任何固体物质。对于输尿管残端有结石的患者，内镜评估应作为首要步骤，因为钙乳可能是梗阻系统中看似结石负荷较大的病因。
