PURPOSE The supine position has potential advantages over the prone position for percutaneous nephrolithotripsy but it is neglected by most urologists. We analyzed the efficacy and safety of percutaneous nephrolithotripsy with the patient in a modified supine position. MATERIALS AND METHODS In a prospective study 88 consecutive patients underwent(More)
PURPOSE The impact of pelvic floor muscle training on the recovery of urinary continence after radical prostatectomy is still controversial. We tested the effectiveness of biofeedback-pelvic floor muscle training in improving urinary incontinence in the 12 months following radical prostatectomy. MATERIALS AND METHODS A total of 73 patients who underwent(More)
PURPOSE: Animal bites to the external genitalia are rare. We retrospectively evaluated our experience with treating genital trauma caused by animal attacks. MATERIALS AND METHODS: We studied the medical records of 10 patients treated in the surgical emergency department at our hospital who presented with genital injury caused by an animal bite from 1983 to(More)
AIMS We evaluated the effect of botulinum toxin type A (BTX-A) injections in the trigone on the antireflux mechanism and evaluated its short-term efficacy. MATERIALS AND METHODS Between April and December 2006, 21 patients (10 men and 11 women) were prospectively evaluated. All were incontinent due to refractory NDO and underwent detrusor injection of 300(More)
OBJECTIVES To examine a new prosthesis, the Adjustable Continence Therapy (ProACT), to determine its ability to treat effectively post radical prostatectomy urinary incontinence. Urinary incontinence is one of the most significant complications of radical prostatectomy. Although the artificial urinary sphincter (AUS) is considered the standard treatment for(More)
INTRODUCTION Lower urinary tract symptoms (LUTS) are common in men over 50 years of age due to prostate enlargement. Diabetes mellitus is also more prevalent in this group. LUTS may result from bladder outlet obstruction (BOO) secondary to prostate enlargement or bladder dysfunction secondary to diabetes or even from a combination of both. OBJECTIVES The(More)
Large-conductance voltage- and calcium-activated potassium (BK) channels have been shown to play a role in detrusor overactivity (DO). The goal of this study was to determine whether bladder outlet obstruction-induced DO is associated with downregulation of BK channels and whether BK channels affect myosin light chain 20 (MLC(20)) phosphorylation in(More)
PURPOSE Tadenan is a plant extract from Pygeum africanum used in the treatment of benign prostatic hyperplasia, to protect the bladder from contractile dysfunction induced by partial bladder outlet obstruction (BOO). The aim of the present study was to determine whether the Tadenan-induced return of detrusor contractility affects the expression of myosin(More)
AIMS We assessed the lower urinary tract symptoms (LUTS) of patients with Parkinson's disease (PD) and their association with different clinical parameters. METHODS We prospectively evaluated 110 patients (84 men), with a mean age of 61.8 +/- 9.6 years. Mean duration of the disease was 12.3 +/- 7.2 years. Neurological impairment was assessed by the(More)
STUDY DESIGN Retrospective study. OBJECTIVE To determine if spinal cord injuries due to gunshot wounds (GW) are associated with different bladder and sphincteric behavior compared to other trauma mechanisms. SETTING Spinal injury center, Brazilian university hospital. METHODS We retrospectively evaluated the records and urodynamic studies of 71(More)
