Prevalence of frailty syndrome in urological patients undergoing major elective surgical procedure due to malignancy.

Introduction: The group of elderly urological patients is growing. A majority of urological operations is performed in this group. The current model of preoperative assessment is developed to be effective in younger groups of patients but not in the elderly. Frailty syndrome has been confirmed to be an effective risk stratification tool in many surgical settings. It can be diagnosed using a variety of screening tools, but the only objective tool is comprehensive geriatric assessment (CGA). However it is time consuming, difficult and to our best knowledge, has not been attempted in Polish urological patients. Material and methods: We assessed the prevalence of frailty in elderly urological patients undergoing surgery due to malignancy using CGA and screening tests. A total of 68 patients over 65 years of age qualified to elective major urological surgery underwent the preoperative assessment including use of traditional tools (medical history, physical examination, ASA score), CGA and frailty-screening tests. The 30-day postoperative complications rate using the Clavien-Dindo scale was also evaluated. Results: The mean age of patients was 71 years. The most common procedures were radical prostatectomy (47.1%), radical nephrectomy (36.6%) and radical cystectomy (11.8%). The prevalence of frailty was 39.7% using CGA and 4.4-10.3% using screening tests. The complication rate was significantly higher in frail individuals when using CGA. Conclusions: Frailty is common in urological elderly patients. The CGA is a time-consuming but reliable tool to diagnose frailty syndrome and predict complications. Screening tests can be useful for selecting patients who should undergo CGA but their predictive value is low.
