A cohort of 235 subjects, who underwent radical prostatectomy from 1994 to 2002, completely continent at the 2-year follow up and with the last follow-up visit in 2009, was examined to assess incidence and risk factors of late-onset incontinence. Median follow up was 100 months, range 84-176. At the last follow-up visit, 209 (89%) maintained continence, and 26 (11%) became incontinent. Specifically 14 out of 26 (6%) used one pad and 12 (5%) used two or more pads daily. Incidence of age ≥ 65 years at radical prostatectomy was greater in the subgroup who developed late incontinence, 109/209 (52%) vs 19/26 (73%). Incidence of adjuvant or salvage radiotherapy, of hormonal manipulation and of extraprostatic disease was similar in the two subgroups. Univariate and multivariate analysis did not disclose any difference. Late-onset incontinence is to be expected in about 10% of subjects who became completely continent after radical prostatectomy. The cause is likely to be related to ageing. Patients should be informed about the long-term risk of becoming incontinent.
