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 S70 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 mon ths n arrowed from the sec ond quarter of the study period.Among youn ger patie nts,age,robot-assisted RP,prostate volume,membra nous urethral length(MUL),and NVB savi ng 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 inhere nt fun ction of the urinary sphi ncter,were predictors of recovery of UC in patients aged>70 years.
