Objective To determine the outcome 10 years after an individual course of p
elvic floor muscle (PFM) exercises for genuine stress incontinence.
Patients and methods Postal questionnaires were sent to 52 women who had un
dergone PFM training 10 years earlier, and their medical files were reviewe
d. The main outcome measures were the patients' self-assessment of therapy
outcome, the frequency of PFM exercises at home, and the demand for surgery
after physiotherapy.
Results Forty-five women (87%; mean age 61 years) were suitable for analysi
s. On completing the course of PFM exercises, physiotherapy had been appare
ntly successful in 24 (53%), and considered to have failed in 21 women (47%
). Sixteen of the 24 successful patients remained satisfied with their urin
ary continence when reassessed 10 years later; two women had undergone surg
ery (8%). In the group where physiotherapy initially failed, five women (24
%) who had not had surgery claimed to be much improved; 13 women (62%) had
undergone surgery. Overall, women in whom the conservative treatment: of st
ress incontinence had produced an improvement over the 10 years had practis
ed PFM exercises more regularly (76%) than the others (55%; not significant
). However, an active voluntary PFM contraction before a sudden intra-abdom
inal pressure rise ('perineal lock') appeared to be responsible for most of
the success.
Conclusions When PFM training is initially successful, there is a 66% chanc
e that the favourable results will persist for at least 10 years.
