    Dysfunctional voiding in women: which muscles are responsible?

    Br J Urol 1998 Dec;82(6):814-9
    Department of Urology, Technical University of Munich, Germany.
    Objective: To analyse the striated external urethral sphincter (EUS) and pelvic floor muscles using two different electromyography (EMG) techniques in women with dysfunctional voiding and/or urinary retention.

    Patients And Methods: Fifteen women (mean age 38.2 years, range 18-61) with dysfunctional voiding and/or unexplained voiding dysfunction associated with urinary retention were examined neurologically and urologically; urodynamics and kinesiological EMG of the bilateral pubococcygeal and external urethral striated sphincter muscles were obtained. In an additional neurophysiological session, concentric-needle EMG of the external urethral sphincter was performed.

    Results: Kinesiological EMG recordings revealed inappropriate pelvic floor muscle activation during voiding in 11 and EUS activation in four women. Concentric needle EMG of the EUS revealed complex repetitive discharges in the four women with inappropriate urethral sphincter activation recorded by kinesiological EMG during voiding. Biofeedback training led to improvement in women with inappropriate pubococcygeal activation but not in those with urethral sphincter complex repetitive discharges.

    Conclusion: Urodynamic examinations in combination with kinesiological EMG examination of the pubococcygeal and external urethral sphincter muscles revealed two groups of women with dysfunctional voiding. Further diagnostic evaluation of such patients with concentric-needle EMG is mandatory. The differentiation of the two groups is therapeutically relevant.

    Loyola University Medical Center, Maywood, IL, USA.
    Objective: To compare interpretations of electromyographic (EMG) recordings from perineal surface patch electrodes (PSPEs) to those from urethral concentric needle electrodes (CNEs) during voiding.

    Patients And Methods: Consenting women underwent urodynamic testing with a 30 G, 3.8 cm CNE at the 12 o'clock position in the striated urethral sphincter muscle, and with PSPEs placed at the 2 and 10 o'clock positions around the anus. Read More

    Department of Urology, New York University School of Medicine, New York, New York, USA.
    Purpose: We characterized presenting symptoms and urodynamic findings in women with dysfunctional voiding.

    Materials And Methods: We reviewed the charts of 26 women diagnosed with dysfunctional voiding. Those with a known or suspected history of neurological disease before evaluation were excluded from study. Read More
    The usefulness of a minimal urodynamic evaluation and pelvic floor biofeedback in children with chronic voiding dysfunction.
    BJU Int 1999 Dec;84(9):1054-7
    Department of Urology, Paediatric Surgery, Rouen University Hospital, Rouen, France.
    Objective: To report our experience of assessing children with chronic voiding dysfunction (>6 months' duration) using a minimal urodynamic evaluation, and the management of detrusor-sphincter dyscoordination (DSdc) using pelvic floor biofeedback.

    Patients And Methods: From 1994 to 1997, 120 children (mean age 7.5 years) with three predominant and associated symptoms were referred to one urologist; they had nocturnal enuresis (28 children), urge incontinence (42) or urinary tract infection (50). Read More

    Clinic of Physical Medicine, Rehabilitation and Prosthetics, Clinical Centre Nis, Nis, Serbia.
    Background: Dysfunctional voiding (DV) in neurologically normal children is characterized by involuntary intermittent contractions of either the striated muscle in external urethral sphincter, or the pelvic floor during voiding. Urinary incontinence, pelvic holding maneuvers, voiding difficulties, urinary tract infections (UTIs), constipation and vesicoureteral reflux are highly associated with DV.

    Aim: To investigate the role of abdominal and pelvic floor muscle (PFM) retraining in children with DV. Read More
