摘要

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.
