Filter by:The purpose of this study is to find out whether plantarflexion has an effect on the degree of urinary urgency and on the amplitude of detrusor contraction during filling cystometry in patients with detrusor overactivity (DO).
Persistent detrusor overactivity (DO) after transurethral prostatectomy results in symptomatic failure in more than one third of the patients. Storage symptoms are major complaints in the early postoperative period after Holmium Laser Enucleation of the Prostate (HoLEP). Levels of the urinary nerve growth factor (NGF), produced by bladder urothelium and smooth muscle, are increased in the patients with overactive bladder (OAB), and decreased after the OAB symptoms were improved. Also, urinary NGF levels are increased in patients with benign prostatic obstruction (BPO), but the changes of the NGF levels after relief of the BPO by the medical or surgical treatment have not been fully investigated. If the elevated urinary NGF levels are reduced after successful surgical treatment of BPO, measurement of urinary NGF could be a useful objective tool to assess the therapeutic outcomes of the operation. The aims of this study are to measure the urinary NGF levels in patients with BPO and to compare the results between the patients with detrusor overactivity (DO) and without detrusor overactivity (Non-DO), average 2 weeks before Holmium Laser Enucleation of the Prostate (HoLEP) procedure. After HoLEP, urinary NGF levels are rechecked at the periods of postoperative 3 months and 6 months, and compare changes between the two groups.
In the last years, botulinum toxin type A (onab/A) has been increasingly used as a treatment option for overactive bladder symptoms in patients affected by either neurogenic and idiopathic detrusor overactivity (DO). How onab/A injected into the detrusor muscle improves overactive bladder symptoms in neurologic patients has been only partially investigated.Some evidence suggested that the neurotoxin probably reduces detrusor muscle contraction blocking detrusor muscle cholinergic innervation. However, recent experimental observations indicated that onab/A determines more complex effects on bladder activity acting on afferent innervations as well as on the efferent one. Only few experimental studies have investigated the activity of onab/A on bladder afferent nervous transmission. Experimental studies in animals showed that Nerve Growth Factor (NGF) elicits increased sensation, urgency and DO. Although there are some evidence on the ability of onab/A to improve DO and to reduce bladder and urinary content of NGF, how onab/A influences NGF expression and the expression of TrKa, p75 and TRPV1 receptors is still unclear. The hypothesis is that onab/A reduces NGF bladder tissue levels and in the same time it modulates the gene expression of NGF associated receptors (TrkA, p75 and TRPV1).
The purpose of this study is to find out whether swallowing has an effect on the degree of urinary urgency and on the amplitude of detrusor contraction during filling cystometry in patients with detrusor overactivity (DO).
This study will evaluate the safety and efficacy of Oxybutynin Chloride 10% Topical Gel in children 3 to less than 17 years old, who have overactive bladder due to a neurogenic condition. Children will be treated with 0.75 g of gel/day for two weeks. Patients will then return to the clinic for a potential dose titration. At this time their dose may be adjusted up to 1g/day, down to 0.5g/day, or remain the same at 0.75g of gel/day depending on the individual response and tolerability. The total treatment time is 14 weeks and total time on the study is 16 weeks.
The objective of this study is to explore the effects of darifenacin in patients with multiple sclerosis and neurogenic detrusor overactivity. The efficacy, safety and tolerability of darifenacin are already well established in idiopathic detrusor overactivity. Patients with multiple sclerosis and neurogenic detrusor overactivity without detrusor-sphincter-dyssynergia (DSD) will be allocated to darifenacin therapy.
