Objectives: To investigate the effectiveness and advantages
of pelvic floor biofeedback therapy applied to treat urinary
incontinence after transurethral resection of the prostate (TURP).
Methods: 24 cases of urinary incontinence after TURP were
treated by biofeedback, pelvic floor stimulation. The patients
whose average age was 59 all underwent TURP, and urinary
incontinence after surgery had lasted for 2 weeks to six months.
There were 15 cases of mild incontinence: involuntary release
of urine only a few milliliters at a sharp, sudden increase in
intra-abdominal pressure, sneezing or laughing); 7 cases of
moderate incontinence: clinical symptom appear during breath
holding or exertion; 2 cases of severe incontinence: loss of
urine in stationary position (standing but not sitting). The anal
working electrode was inserted into the anus with the patients
in lateral position, The insertion depth of the working electrode
was adjusted to make sure that the surface electrode located
in the perianal region, and set the stimulation parameters to
the excitement that without pain to the patients, stimulation
duration was 10 s every time. The patients were instructed to
contract pelvic floor muscle immediately during feedback, and
to relax before the next stimulus. The exercise of pelvic floor
muscle contraction and relaxation was carried out alternately.
Each treatment lasted for 20 minutes and was performed twice
a day, 5 days a week, 1-3 months as a course. At the intermittent
period and after the termination of the therapy, the patients
were required to do pelvic floor muscles exercise approximately
300 times and to carry out the exercise 3 times a day.
Results: After 2-3 months of therapy, no urinary incontinence
was perceived by 22 patients of mild and moderate incontinence.
The therapies of 2 cases of severe incontinence were extended to
6 months. Comparison of the detection of urodynamic leak point
pressure between pre and post treatment showed statistically
Conclusions: To strengthening the pelvic floor muscle function
and improve the stability of detrusor is an important way to treat
urinary incontinence. Electrical stimulation of the pelvic floor
muscles can inhibit the contraction of bladder, and is of positive
treatment value in unstable bladder and urge incontinence.
Furthermore, it can increase the contraction of urethral sphincter and strengthen the function of urethral closure. Pelvic floor
electrical stimulation is a safe and effective therapy for urinary
incontinence after TURP.
