Migration of LAPRA-TY Clips in Ureter and Collecting System Mimicking Urinary Stones Following Laparoscopic Partial Nephrectomy
Abstract
We present a rare case of the clip migration after laparoscopic partial nephrectomy in which the clips were misdiagnosed as urinary stones. A 57-years-old female presented with right flank pain 3 months after the surgery. A computed tomography scan showed a 4 mm stone in the left upper ureter and hydronephrosis. Another 3 mm stone was also detected in the left upper calyx. Rigid ureteroscopy and flexible ureterorenoscopy revealed two LAPRA-TY clips, which were embedded in the upper ureter and calyx. The clips were fragmented by holmium laser lithotripsy and removed with stone basket. Pain and hydronephrosis are resolved at follow-up.
