OBJECTIVE To compare the effects of tamsulosin and prazosin on clinical and urodynamic parameters in women with voiding dysfunction. METHODS Forty women aged 20-65 years with a clinical diagnosis of voiding dysfunction were blindly randomized to two equal groups for treatment with tamsulosin 0.4 mg or 1-2 mg of prazosin daily. Symptom assessment with the American Urological Association Sympto...

AIMS To evaluate the correlation between an urgency severity scale (USS) based on a voiding diary with detrusor overactivity (DO) in a videourodynamic study in patients with an overactive bladder (OAB). METHODS We prospectively enrolled 190 consecutive patients with OAB. All patients were assessed using a USS and completed a 3-day voiding diary that recorded urgency and urgency urinary incont...

OBJECTIVES To evaluate the value of performing urodynamic investigations in the assessment of women with a history of pure stress urinary incontinence (SUI). METHODS Consecutive women with lower urinary tract symptoms were studied retrospectively. Urinary symptoms were determined from the frequency-volume chart and symptom section of the King's Health Questionnaire. Only women with pure SUI s...

OBJECTIVES To develop a urodynamic model incorporating external urethral sphincter (EUS) electromyography (EMG) in awake rats. MATERIALS AND METHODS Bladder catheters and EUS EMG electrodes were implanted in female Sprague Dawley rats. Assessments were performed in awake, lightly restrained rats on postoperative day 12-14. Measurements were repeated in the same rat on day 16 under urethane an...

BACKGROUND The aim of this study is to identify the differences between patients with overactive bladder (OAB) and detrusor overactivity (DO) and those with OAB but without DO. METHODS We prospectively recruited patients with OAB symptoms between December 2008 and September 2009. All patients were required to complete a 3-day frequency-volume chart. Symptom severity was evaluated using the In...

PURPOSE We examine various mechanisms of post-radical prostatectomy incontinence. MATERIALS AND METHODS A total of 83 consecutive men (mean age 68 +/- 6.6 years) referred for evaluation of persistent post-radical prostatectomy incontinence were enrolled in the study. All patients underwent clinical and urodynamic evaluation. Final diagnosis was based on clinical judgment considering patient h...

PURPOSE I studied the effects of various treatments for benign prostatic hyperplasia on urethral resistance. MATERIALS AND METHODS I reviewed the literature on urodynamic effects of treatments for benign prostatic hyperplasia. Articles that reported pretreatment and posttreatment values of relevant urodynamic parameters were analyzed. Average before and after treatment values of maximum flow ...

In 1997, the ICS standard for digital exchange of pressure£ow study data was published (Neurourol. Urodyn. 1997;16: 9 ^18) with the intention of enabling the exchange of urodynamic data and curves between equipment of di¡erent manufacturers. Initially, the purpose of the standard was to make it possible to carry out multi-centre trials with di¡erent brands of equipment in the di¡erent centres, ...

The aim of this study was to characterize pharmacological effects of gosha-jinki-gan (GJG) and green tea extract (GTE), on urodynamic parameters, bladder receptors, and urinary cytokines in rats with cyclophosphamide (CYP)-induced cystitis. Urodynamic parameters in CYP-treated rats were measured using the cystometric method. Muscarinic and purinergic receptors in rat tissues were measured by ra...

Barrington's nucleus, in the pons, regulates micturition through spinal projections to preganglionic parasympathetic neurons. The stress neuropeptide CRF is prominent in these projections and has an inhibitory influence. Social stress in rats causes urinary retention and abnormal urodynamics resembling those produced by partial bladder outlet obstruction (pBOO), and this is associated with CRF ...
