Sukapiriya C and Bandidwattanawong C. Urol Case Rep 2020.
Synchronous double primary RCC and TCC of the renal pelvis and bladder are extremely uncommon. Proper management is a medical dilemma, and no standard treatment strategy has been agreed upon for this rare situation. Our case involved a large mass in the right kidney and multiple masses in the left renal pelvis, ureter, and bladder. Aggressive management was adopted, including multiagent neoadjuvant chemotherapy, cystectomy and nephroureterectomy, which resulted in an excellent outcome, although
our patient will require life-long hemodialysis.
