An Unexpected Finding in a Patient with Suspected Urothelial Recurrence during Surveillance Post Radical Cystoprostatectomy for Urothelial Bladder Carcinoma

We report a 79-year-old gentleman with an asymptomatic intra-ureteric encrusted suture thread. He was found to have calcification in the left renal pelvis and thickening of the upper ureteric wall on a follow-up computerised tomography (CT) scan ten years after a radical cystoprostatectomy and ileal conduit formation for bladder and prostate cancer. These incidental CT scan findings raised the possibility of either ureteric stone or tumour. Subsequently, the patient underwent a ureterorenoscopy, which revealed a calcified 6cm length thread thought to be a suture that slipped intraoperative during his initial radical surgery ten years earlier.
