Highlights • Foreign bodies, such as suture materials, mesh, cotton swab, Hem-o-lok clips, metallic clips, coils used for angioembolization etc. are rare causes of urinary tract stone disease.• Clinicians should be aware of the possibility of migrated hem-o-lok clips serving as a nidus for urinary tract stone formation in patients who have undergone endoscopic PN.• Attention to suture tension during endoscopic partial nephrectomy may reduce the risk of clip migration.• Laser lithotripsy of the calculous cortical rim around the Hem-o-lok clip(s) and removal of the denuded foreign body under direct endoscopic visualization are strongly advisable, since Hem-o-lok clips are usually SWL-resistant.
