Abstract

Objective To report (i) the estimated glomerular filtration rate (eGFR) changes in patients undergoing radical nephro-ureterectomy (RNU) for upper tract urothelial carcinoma (UTUC); (ii) the rate of change in eGFR in patients eligible for cisplatin-based chemotherapy; and (iii) the association of preoperative, postoperative and rate of change of renal function variables with survival outcomes. Patient and Methods We performed a retrospective analysis of 666 patients treated with RNU for UTUC at seven international institutions from 1994 to 2007. The eGFR was calculated at baseline and at 3-6 months (Modification of Diet in Renal Disease formula (MDRD) and Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EP) equations). Results The median (interquartile range) eGFR decreased by 18.2 (8-12)% after RNU. A total of 37% of patients had a preoperative eGFR ≥ 60 mL/min/1.73 m2, which decreased to 16% after RNU (P < 0.001); 72% of patients had a preoperative eGFR ≥ 45 mL/min/1.73 m2, which decreased to 52% after RNU (P < 0.001). The distributions were similar when analyses were restricted to patients with locally advanced disease (pT3-pT4) and/or lymph node metastasis. Patients older than the median age of 70 years were more likely to have a decrease in eGFR after RNU (P < 0.001). None of the renal function variables was associated with clinical outcomes such as disease recurrence, cancer-specific and overall mortality; however, when analyses were restricted to patients who had no adjuvant chemotherapy and did not experience disease recurrence (n = 431), a preoperative eGFR ≥ 60 mL/min/1.73 m2 (P = 0.03) and a postoperative eGFR ≥ 45 mL/min/1.73 m2 (P = 0.04) were associated with better overall survival in univariable analyses. Conclusions In patients who had UTUC, eGFR was low and furthermore, it significantly decreased after RNU. Renal function did not affect cancer-specific outcomes after RNU.
