4 Clinical Trials for Various Conditions
Dysfunctional voiding is often associated with constipation. The association of constipation with urologic pathologic processes has previously been described since the 1950's, but it was only over the past decade that clinicians have paid more attention to this relationship and recognized it existence with the term dysfunctional elimination syndrome (DES). This term is used to reflect the broad spectrum of functional disturbances that may affect the urinary tract including that of functional bowl disturbances and can be classified as follows: * Functional disorder of filling: overactive bladder, over distention of bladder or insensate bladder, which may be associated with fecal impaction or rectal distention with infrequent bowel movements * Functional disorder of emptying: over-recruitment of pelvic floor activity during voiding causing interrupted and/or incomplete emptying also associated with defecation difficulties due to non- relaxation of the puborectalis muscle, dyssynergic defecation or pain with defecation Several different therapeutic options have been used for patients with dysfunctional voiding mainly to decrease bladder outlet obstruction. These treatments including, alpha adrenergic antagonists, and botulinum toxin are less than optimum. One possible explanation for these drug failures includes the inability of these medications to relax the striated muscles of the pelvic floor necessary for voiding. To date there has been no data to evaluate the role of baclofen on the striated muscle of the external anal sphincter, essential in the defecation process.
The goal of the DIVA trial is to test the effectiveness of at-home diaphragmatic breathing exercises with bladder hygiene education in female patients with symptoms of difficulty urinating (dysfunctional voiding). It aims to answer how effective are at-home diaphragmatic breathing exercises for dysfunctional voiding. Researchers will compare two groups of participants (a group using diaphragmatic breathing exercises with bladder hygiene education versus a group using just bladder hygiene education alone) for a total of 4 weeks. Participants will complete weekly surveys on their symptoms.
Randomized clinical trial using phenazopyridine to decrease voiding dysfunction after a retropubic midurethral sling operation.
The target population of this study is children with primary or secondary daytime urinary incontinence, who have failed to improve adequately despite compliance with at least 6 months of standard medical therapy. The study hypothesis is that patients who under go cutting the filum terminale - the string-like lower end of the spinal cord - will have improved bladder function at 6-month follow up. Bladder function and its effects on quality of life will be measured before surgery and at 6-month follow up.
