We evaluated contemporary trends in radical prostatectomy (RP) in men aged >70 years and investigated associations of selected variables with recovery of urinary continence (UC) in two age groups: >70 and ≤ 70 years. A retrospective cohort of 2301 eligible patients attending our institution from 2004 to 2015 was reviewed. Patients were divided into two groups based on age at surgery (>70 years [n = 610] vs 70 years [n = 1691]) and four groups by year of surgery. Over the study period, the proportion of patients aged >70 years gradually increased up to 30.0%, and the rate of robot-assisted RP and neurovascular bundle (NVB) saving increased continually to 80.0% and 67.4% of older patients, respectively. Although the rate of recovery of UC within 12 months (3 months) in patients aged >70 years was lower than that in those aged ≤ 70 years (81.5% [52.6%] vs 88.6% [60.9%], respectively; both P < 0.001), the gap between age groups in the rate of recovery within 12 months narrowed from the second quarter of the study period. Among younger patients, age, robot-assisted RP, prostate volume, membranous urethral length (MUL), and NVB saving were predictors of recovery of UC within 3 or 12 months. In contrast, only age and MUL were predictors of recovery of UC within 3 and 12 months in patients aged >70 years. Therefore, unlike younger patients, only variables (age and MUL), possibly associated with the inherent function of the urinary sphincter, were predictors of recovery of UC in patients aged >70 years.
