Ureteroscopic Lithotripsy for A Surgical Clip-Induced Renal Stone Following Laparoscopic Partial Nephrectomy.

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.
