PURPOSE: Sacral nerve modulation appears to offer a valid treatment option for some patients with fecal incontinence and functional defects of the internal anal sphincter or of the striated muscle. METHODS: Sixteen patients with fecal incontinence (4 males; mean age, 51.4 (range, 27-79) years) with intact or surgically repaired (n ...

OBJECTIVE: Assessments of the pathophysiology of fecal incontinence are skewed toward anal sphincter function; however, rectal compliance, rectoanal sensation and capacity may also be relevant. The aim of this study was to evaluate the usual and some novel diagnostic approaches in fecal incontinence. METHODS: In 22 unselected patients with fecal ...

PURPOSE: Preliminary studies have shown improvement in fecal incontinence in several patients who received temporary or permanent stimulation. The purpose of this study was to report our experience in sacral nerve stimulation in the treatment of fecal incontinence and to target patients who would benefit most from stimulation. METHODS: Patients ...

Two case reports are presented of bradycardia in two elderly patients, which was resistant to atropine but which resolved immediately the acute bladder distension was treated. Generally, a sympathetic cardiac response is expected, and this paradoxical response may be due not only to lesions of the reflex loop involving both ...

PURPOSE: The augmented valved rectum and double folded rectosigmoid bladder represent 2 modifications of ureterosigmoidostomy. Both procedures improve continence by lowering the reservoir pressure. We present the outcome of these techniques on the upper urinary tract, continence, metabolic profile, linear growth and bone density. MATERIALS AND METHODS: Between March 1987 ...

Different conservative treatment modalities for the lower urinary tract dysfunction in patients with spinal cord lesion are reviewed. Conservative treatment is still the mainstay of the urological management in these patients. Growing experience has changed the classical approach. Spontaneous voiding with and without triggered voiding and/or bladder expression has proven ...

Water cystometry was done according to the recommendations of the International Continence Society [Abrams ...

Early detection of transitional cell carcinoma (TCC) of the urinary bladder is essential for effective treatment. While several serum markers have been evaluated, none have been widely accepted for practical clinical use. Thus, urinary markers have been introduced and investigated to detect the evidence of bladder cancer. But sensitivity and ...

The majority of patients with multiple sclerosis (MS) experience genitourinary and bowel dysfunction over the course of their illness. Lower extremity pyramidal signs are excellent predictors of concurrent bladder dysfunction. Constipation is the most common bowel dysfunction, which results from a range of causes including pelvic floor spasticity, decreased gastro-colic ...

Fecal incontinence occurs frequently in both men and women. Yet, few studies on fecal incontinence have separated the evaluation and interpretation of data by gender. This study was designed to identify differences in the clinical, anorectal manometry, and electromyography (EMG) characteristics between male and female patients with fecal incontinence. We ...

BACKGROUND: Micturitional disturbance is known to occur in subacute myelo-optico-neuropathy (SMON).
