[Transrectal sonography biofeedback training (TSB). Incontinence training after radical prostatectomy]

Area of Science:

• Urology
• Medical Technology
• Rehabilitation

Background:

• Severe urinary incontinence is a common complication following radical prostatectomy (RP).
• Current biofeedback methods like video urethrocystoscopy are invasive.
• Transrectal sonography biofeedback training (TSB) offers a less invasive alternative for visualizing external urethral sphincter muscle contractions.

Purpose of the Study:

• To evaluate the efficacy and patient acceptance of transrectal sonography biofeedback training (TSB) for treating urinary incontinence post-RP.
• To assess TSB's ability to help patients visualize and control their sphincter muscle function.

Main Methods:

• 100 patients with post-RP urinary incontinence underwent TSB.
• Patients visualized external urethral sphincter contractions using ultrasound during attempted urine stream reduction.
• The reduction in fluid column diameter correlated with sphincter contraction strength.

Main Results:

• TSB was successful in 88% of patients, demonstrating differentiated sphincter tension.
• 96% of patients found TSB helpful in restoring continence.
• Pain or inability to detect the sphincter affected 8% and 4% of patients, respectively.

Conclusions:

• Transrectal sonography biofeedback training (TSB) is a viable and well-accepted method for treating urinary incontinence after radical prostatectomy.
• TSB effectively visualizes sphincter muscle function, aiding patient recovery.
• While minor limitations exist, TSB demonstrates significant patient benefit in restoring continence.
