Horseshoe kidney is a congenital renal fusion abnormality that can be complicated by stones; in rare cases, it has also been associated with a duplex collecting system. We present images of a horseshoe kidney with a right partial duplex collecting system that was not detected on the preoperative computed tomography scan. The use of a prone-split leg position for percutaneous nephrolithotomy facilitated the performance of flexible ureterorenoscopy of the lower pole moiety and percutaneous nephrolithotomy of the upper pole moiety in 1 setting with complete stone clearance.
马蹄肾是一种先天性肾脏融合异常，可并发结石；在极少数情况下，它也与双肾盂收集系统有关。我们展示了一个马蹄肾的图像，其右侧部分为双肾盂收集系统，术前 CT 扫描未发现。经皮肾镜碎石术采用俯卧分腿位，便于在 1 次手术中同时进行下极部分的软性输尿管镜检查和上极部分的经皮肾镜碎石术，结石完全清除。
