We report two cases in which the renal stone originated from a foreign body which was used to treat a urinary tract fistula by a gynecologist. The first patient developed a vesicovaginal fistula following an emergency Caesarean operation. At the time of correcting surgery, a 5 Fr ureteral catheter was used as a splint catheter elsewhere, 108 mm of which somehow migrated up to the renal pelvis and a stone was formed 4.5 years later. The second patient underwent a radical hysterectomy for uterine cervical cancer. Postoperatively, a ureterovaginal fistula developed, for which a double-J ureteral catheter was indwelt. When she visited our clinic 6 months later, we found the double-J catheter and renal stone in her left renal pelvis. In both cases the catheters and renal stones were successfully removed by means of the percutaneous nephrolithotomy (PNL).
我们报告了两例肾结石起源于异物的病例，这些异物是由妇科医生用于治疗尿路瘘的。第一例患者在急诊剖宫产术后发生膀胱阴道瘘。在进行矫正手术时，一根5F输尿管导管被用作其他部位的支撑导管，其中108mm不知何故向上迁移至肾盂，并在4.5年后形成了结石。第二例患者因子宫颈癌接受了根治性子宫切除术。术后发生输尿管阴道瘘，为此留置了一根双J输尿管导管。6个月后她前来我们诊所就诊时，我们在她的左肾盂中发现了双J导管和肾结石。在这两例病例中，均通过经皮肾镜取石术（PNL）成功取出了导管和肾结石。
