Introduction: Hem-o-lok clip migration into the ipsilateral collecting system and formation of a distal ureteral stone after robot-assited partial nephrectomy (PN) is a rare condition of stone disease.
Presentation of case: A 48-year-old male presented with hematuria. Physical examination was unremarkable. Urinalysis showed presence of red blood cells. Serum multiple analysis and ultrasonography were within normal limits. Contrast enhanced abdominal computerized tomography scan revealed an 8-mm right distal ureteral stone, which was not associated with ipsilateral hydronephrosis.
Discussion: With the widespread adoption of minimally invasive surgery, it is not uncommon to utilize foreign bodies as surgical facilitators which also have the potential to migrate to the urothelium-lined urinary tract and act as a stone nidus when used for endoscopic PN CONCLUSION: 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.
