Surgical clips used in laparoscopic and robot-assisted surgeries can occasionally migrate into the upper urinary tract, serving as nidi for stone formation. We report a case of a surgical clip-induced renal stone successfully treated with ureteroscopic lithotripsy (URSL) following laparoscopic partial nephrectomy (LPN).
A 37-year-old male with a 17-mm renal stone in the right middle calyx underwent URSL. His surgical history included right LPN performed four years prior, with operative records documenting pyelocaliceal system entry and Hem-o-lok clip placement. During the operation, a Hem-o-lok clip was identified within the stone. All fragments along with the surgical clip were completely retrieved using a basket forceps after laser lithotripsy.
This case highlights important clinical considerations: the appropriate use of surgical clips during LPN, selection of optimal endourological treatment approaches for stone removal, and the importance of careful follow-up for early detection and intervention of clips and clip-induced stones.
腹腔镜手术和机器人辅助手术中使用的手术夹偶尔会迁移至上尿路，成为结石形成的病灶。我们报告一例腹腔镜肾部分切除术（LPN）后输尿管镜碎石术（URSL）成功治疗手术夹所致肾结石的病例。
一名37岁男性，右中肾盏有一枚17毫米的肾结石，接受了URSL治疗。他的手术史包括4年前进行的右侧LPN，手术记录显示肾盂肾盏系统进入及Hem-o-lok夹放置。手术过程中，在结石内发现一个Hem-o-lok夹。激光碎石术后，使用篮式活检钳将所有碎片及手术夹完全取出。
本病例突出了重要的临床注意事项：LPN期间手术夹的正确使用、选择最佳的腔内泌尿外科取石治疗方法，以及密切随访以早期发现和干预手术夹及手术夹所致结石的重要性。
