BACKGROUND The aim of this study was to compare effective and sham intravaginal electrical stimulation (IES) in treating mixed urinary incontinence. METHODS Between January 2001 and February 2002, 40 women were randomly distributed, in a double-blind study, into two groups: group G1 (n=20), effective IES, and group G2 (n = 20), sham IES, with follow up at(More)
PURPOSE Vesicovaginal fistula (VVF) is one of the most devastating surgical complications that can occur in women. The primary cause remains an abdominal hysterectomy. Approach to this condition can be transvaginal or transabdominal. Laparoscopic repair of VVF may be an alternative approach to this treating rare condition. We present seven cases of VVF(More)
AIMS To assess pelvic floor muscle (PFM) strength in women with stress urinary incontinence (SUI) and urge urinary incontinence (UUI). MATERIALS AND METHODS 51 women were prospectively divided into two groups, according to the symptoms as SUI (G1 = 22) or UUI (G2 = 29). Demographic data, such as number of pads/ 24 hours, number of micturations/ 24 hours(More)
PURPOSE To present our series of patients who underwent laparoscopic correction of iatrogenic lesions and a review of the literature. PATIENTS AND METHODS We evaluated 23 patients who underwent laparoscopic correction of iatrogenic lesions. Thirteen patients had open surgery, 6 had an endoscopic procedure, and 4 had a laparoscopic approach as the first(More)
PURPOSE Several urethral conditions may require tissue substitution. One collagen-base biomaterial that recently emerged as an option is small intestinal submucosa (SIS). The aim of this study was to compare the results of SIS and buccal mucosa for urethral substitution in rabbits. MATERIALS AND METHODS Thirty-six North Folk male rabbits were randomized(More)
OBJECTIVE To evaluate prevalence and risk factors of fecal and urinary incontinence (UI) in Brazilian women.

MATERIALS AND METHODS Between February 2000 and February 2008, 630 patients with urinary calculi were evaluated in the lithiasis outpatient clinic.(More)
To evaluate the protective effect of intravesical oxybutynin on the ultrastructure of rabbits with detrusor overactivity (DO). Seventeen North Folk male rabbits were distributed into three groups: GI (n = 5) used as control, GII (n = 5), and GIII (n = 5) with DO. One animal from GII and one from GIII were excluded because they did not develop DO. In GIII,(More)
OBJECTIVES In a swine model of renal ischemia, we compared the effectiveness of the transurethral retrograde cold saline perfusion technique to the traditional method of renal cooling with ice slush, in achieving adequate parenchymal temperatures for functional preservation of the organ. Physiological and histological effects were also assessed. METHODS(More)
