Schafer et al. [1] showed, in a multicentre, multinational study of men with LUTS suggestive of benign prostatic obstruction (BPO), that many urodynamic traces were dif®cult or impossible to interpret. Subsequent experience with a standardized urodynamic protocol showed a great improvement in the standard of the urodynamics carried out. A standardized urodynamic protocol is now a prerequisite i...

OBJECTIVES To determine the urodynamic efficacy and factors that influence the urodynamic results of treatment of neurogenic detrusor hyperactivity with intradetrusor injection of botulinum toxin type A (BTX-A) in patients with spinal cord injury (SCI). MATERIAL AND METHODS A retrospective study was conducted with a cohort of 70 patients composed of 40 men and 30 women with stable SCI (mean a...

OBJECTIVE To analyse the urodynamic changes subsequent to the placement of TVT tension-free tape (retropubic tension-free vaginal tape) or TVT-O (obturator tension-free vaginal tape). MATERIALS AND METHODS We carried out a retrospective cohort study that included women with urodynamic diagnosis of stress incontinence, in whom we placed type TVT or TVT-O tension-free tape, and on whom we perfo...

Objective: We compared the clinical and urodynamic outcome of men with lower urinary tract symptoms with and without previous urodynamic evaluation submitted to transurethral resection of the prostate. Materials and Methods: A prospective and randomized study was performed in 315 patients who underwent transurethral resection of the prostate. In 151 patients (group A) with a mean age of 63 year...

PURPOSE We assessed the accuracy of urinary detection by visualization compared with a method using the urethral channel of a transurethral, three-channel urodynamic catheter. MATERIALS AND METHODS This was a case series of 52 patients presenting with stress urinary incontinence over 2 years. Patients underwent video-urodynamic studies in both the supine and the erect positions by use of two ...

PURPOSE We investigated the etiologies of lower urinary tract symptoms (LUTS) and compared urodynamic characteristics between different diagnostic groups in young men with chronic LUTS. MATERIALS AND METHODS We reviewed the medical records of 308 men aged 18 to 50 years who had undergone a urodynamic study for chronic LUTS (≥6 months) without symptoms suggestive of chronic prostatitis. RESU...

PURPOSE We evaluated the early clinical and urodynamic results of posterior tibial nerve stimulation in patients with refractory monosymptomatic nocturnal enuresis. MATERIALS AND METHODS We randomly assigned 28 patients with refractory monosymptomatic nocturnal enuresis to 2 equal groups. Group 1 received a weekly session of posterior tibial nerve stimulation for 12 weeks and group 2 was the ...

OBJECTIVE The study has been undertaken to determine the reproducibility of lower urinary tract symptoms in female patients after urodynamic investigations. DESIGN A Descriptive study with retrospective analysis of data. SETTING Combined Military Hospital Rawalpindi and Armed Forces Institute of Urology, Rawalpindi. METHODS Fifty consecutive women with a primary history of urinary inconti...

PURPOSE Posterior urethral valves are the most common cause of congenital obstructive uropathy leading to renal failure in childhood. We investigate the influence of bladder dysfunction on renal function impairment. MATERIALS AND METHODS We retrospectively reviewed the records of 116 patients with posterior urethral valves. After valve ablation urodynamic studies were performed in all patient...

BACKGROUND Urodynamic studies are commonly performed in women before surgery for stress urinary incontinence, but there is no good evidence that they improve outcomes. METHODS We performed a multicenter, randomized, noninferiority trial involving women with uncomplicated, demonstrable stress urinary incontinence to compare outcomes after preoperative office evaluation and urodynamic tests or ...
