An Unusual and Rare Metachronous Ipsilateral Ureteric Stump Metastasis Post Radical Nephrectomy

摘要

We report a case of recurrence of chromophobe renal cell cancer in the ipsilateral ureteric stump eight years later after the primary tumor was excised successfully. Before this detection of the recurrence, the patient had presented with recurrent episodes of hematuria four years after the radical nephrectomy was performed and the investigations were inconclusive. Eventually, the lesion was detected on flexible cystoscopy in the area of the right ureteric orifice protruding in the bladder. Transurethral resection of the tumor surprisingly revealed a chromophobe renal cancer with similar features seen in the primary tumor specimen. The patient underwent robotic-assisted laparoscopic excision of the ureteric stump with a cuff of the bladder and has been recurrence-free for five years on regular surveillance scans.
