title: [Urothelial carcinoma after renal transplantation : a case report].
abstract: We report a case of urothelial carcinoma (UC) in a 69-year-old man that occurred after renal transplantation. He had started receiving hemodialysis therapy in 2004 due to diabetic nephropathy and underwent living related renal transplantation from his brother in 2005. He was referred to our hospital in May 2009 with asymptomatic microscopic hematuria. Cystoscopy findings revealed multiple bladder tumors, and transurethral resection of bladder tumor (TUR-BT) followed by intravesical instillation of pirarubicin was performed. Histopathological findings revealed UC (G1>G2, pTa). Cytology findings after the operation did not become negative; urine specimen from the native right ureter was positive, and abdominal computed tomography (CT) demonstrated a right pelvic tumor. In January 2010, a laparoscopic right nephroureterectomy was performed and pathological examination findings revealed UC in the right pelvis (G3>G2, INFβ, pT3). In March 2010, recurrence of the bladder tumor was demonstrated as carcinoma in situ (CIS) of the bladder and left native ureter. In June 2010, a radical cystectomy with left nephroureterectomy and ileal conduit diversion were performed. One week after that operation, laboratory results revealed abnormal hepatic function and CT showed multiple liver metastases. The patient died in August 2010, 2 months after surgery.
