A 32-year-old man was referred to a tertiary care center for stone management. The patient had initially presented to his primary physician 3 months earlier with right flank pain of 2 month's duration. Abdominopelvic ultrasonography and intravenous urography had revealed left-to-right crossed fused renal ectopia with a 25 mm opaque stone in the crossed kidney. The patient had received two sessions of extracorporeal shock wave lithotripsy, which had failed to remove the renal stone.
Noncontrast CT, blood tests (hemoglobin and creatinine levels), abdominopelvic ultrasonography and intravenous urography.
Left-to-right crossed fused ectopia with a 25 mm opaque renal stone in the anomalous kidney.
The patient underwent laparoscopic nephrolithotomy to remove the renal stone. Intravenous urography and abdominopelvic ultrasonography 1 month after surgery confirmed that the patient was stone free and had functional renal units. The patient will be followed up every 3 months with abdominopelvic ultrasonography for early detection of stone recurrence.
一名 32 岁男性因结石管理被转诊至三级医疗中心。患者最初于 3 个月前因右侧腰痛就诊，疼痛持续 2 个月。腹部超声和静脉尿路造影显示左右交叉融合肾异位，交叉肾中有 25mm 不透光结石。患者接受了两次体外冲击波碎石治疗，但未能去除肾结石。
非增强 CT、血液检查（血红蛋白和肌酐水平）、腹部超声和静脉尿路造影。
左右交叉融合异位，异常肾中有 25mm 不透光肾结石。
患者接受了腹腔镜肾切开取石术以去除肾结石。术后 1 个月静脉尿路造影和腹部超声检查证实患者无结石且肾功能正常。患者将每 3 个月通过腹部超声进行随访，以早期发现结石复发。
