Biofeedback: Is it effective for urethral sydnrome?

초록

Introduction: The term urethral syndrome is used liberally to label the symptoms of frequency and voiding dysfunction, commonly seen in urology clinics. Pain or discomfort also tends s to be a major component of this condition. Recently urodynamic studies are now integral to the understanding and diagnosis of the urethral syndrome. Urodynamically, higher - than-normal closure pressures in the external sphincter and spastic behavior presented in the majority of patients with these conditions. And clear correlation between irritative symptoms and spacity or non-relaxation of the urethral sphincter can be demonstrated. So it can be induced that the voluntary relaxation of urethral sphincter can be a non - invasive, cost effective therapeutic alternatives. Aims of Study: To evaluate therapeutic value of biofeedback in management of irritative voiding symptoms that are correlated pain or discomfort was the goal of the study Methods: Eighteen consecutive patients were studied with EMG biofeedback. Most dominants complain was pain or discomfort combined with irritative voiding symptoms. But if there was infection findings, the patients were excluded. Every session, each patient exercised pelvic floor muscles for 20 min (not for strengthening but for relaxation) with understanding of voiding physiology. Session interval changed once a week from twice a week after acquiring exercise skills. 12 session routinely. To facilitate the awareness and relaxation, low pulse frequency electrical stimulation added Result: After 5-6 session (2-3 week), they came to exercise effectively. So most of them, except four cases, can relieve pain or discomfort voluntarily. After that, they're voiding interval increase step by step. Mean micturitions were decreased 6 times a day from above twelve, nocturia changed 3.7 times to 0. 0 -1 time a night. Conclusion: Although the etiology of urethral syndrome is obscure and therapeutic approaches are variable, the chronic voiding dysfunction su
