Abstrakt: Background: Treatment for bladder cancer includes radical cystectomy (RC) and urinary diversion; RC is associated with long-term morbidity, kidney impairment and mortality. Aim: To identify risk factors associated with postoperative long-term kidney function and mortality. Methods: Retrospective study of patients with RC and urinary diversion in Beaumont Hospital from 1996 to 2016. We included patients who had follow-up at least 2 years post-procedure. We assessed estimated glomerular filtration rate (eGFR) preoperatively and yearly post-procedure, dialysis commencement and mortality. Cox and Fine-Gray regression analyses were applied; p-value < 0.05 was considered significant. Results: We included 264 patients, median age 68.3 years, 73.7% males. The most common diagnosis was bladder cancer 93.3%, TNM stages T ≥ 2 75.9%, N ≥ 1 47.6% and M1 28%. The median eGFR preoperative was 65.8 ml/min/1.73m2 and after 2 years 58.2 ml/min/1.73m2 (p: 0.009); 5.3% required chronic dialysis and 32.8% had a decrease > 10 ml/min/1.73m2. Risk factors associated with ESKD and start dialysis included younger age (HR: 0.90, CI 95% 0.87–0.94) and lower pre-operative eGFR (HR: 0.97, CI 95% 0.94–1.00). Overall mortality was 43.2% and 54.1% at 5 and 10 years, respectively; risk factors were older age (HR: 1.04, CI 95% 1.02–1.06), tumour stage T ≥ 2 (HR: 2.22, CI 95% 1.39–3.54) and no chemotherapy (HR: 1.72, CI 95% 1.18–2.51). Limitations include retrospective design, absence of control group and single centre experience. Conclusions: Patients with RC are at risk of progressive kidney function deterioration and elevated mortality and the main risk factors associated were age and preoperative eGFR. Regular monitoring of kidney function will permit early diagnosis and treatment. [ABSTRACT FROM AUTHOR]
