No difference in oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving radical nephroureterectomy.

Patients with end stage renal disease (ESRD) are at high risk of developing upper tract urothelial carcinoma (UTUC). Due to high recurrence rate of UTUC in contralateral kidney and ureter, and high risk of complications related to surgery and anesthesia, whether it's necessary to remove both kineys and ureters at one time remains in debate. We utilized Taiwanese UTUC Registry Database to valuate the difference of oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving surgical resection. Patients with ESRD and UTUC were divided into three groups, unilateral UTUC, previous history of unilateral UTUC with metachronous contralateral UTUC, and concurrent bilatetral UTUC. Oncological outcomes, perioperative complications, and length of hospital stays were investiaged. We found that there is no diffence of oncological outcomes including overall survival, cancer specific survival, disease free survival and bladder recurrence free survival between these three groups. Complication rate and length of hospital stay are similar. Adverse oncological features such as advanced tumor stage, lymph node involvement, lymphovascular invasion, and positive surgical margin would negatively affect oncological outcomes.
