Study summary

To assess the efficacy of botulinum toxin in spastic neurogenic bladder.

Read the detailed description

Neurogenic detrusor overactivity (NDO) can result in lower and upper urinary tract complications and eventually even in end-stage kidney failure. Since the driving force of this clinical cascade is high bladder pressure, controlling intravesical pressure in NDO patients improves both quality of life and life-expectancy in these patients. Botulinum toxin A (BTX-A) has proven its efficacy in reducing intravesical pressure and in reducing incontinence episodes. BTX-A also improves quality of life in patients with NDO. Both onabotulinumtoxinA (Botox®, Allergan, Irvine, USA) and abobotulinumtoxinA (Dysport®, Ipsen, Paris, France) have a level A recommendation for NDO-treatment. The recommended dose for intradetrusor injections in NDO patients is 200 U of onabotulinumtoxinA or 500 U of abobotulinumtoxinA. The drug is generally administered extratrigonal in the detrusor muscle, via cystoscopic guided injection at 20 sites in 1 mL injections. Intradetrusor BTX-A injections are safe, with mostly local complications such as urinary tract infection and high post-void residual or retention. The effect of the toxin lasts for approximately 9 months. Repeat injections can be performed without loss of efficacy. Different injection techniques, novel ways of BTX-A administration, eliminating the need for injection or new BTX-A types with better/longer response rates could change the field in the future.

Botulinum toxins are neurotoxins produced by the facultative anaerobe Clostridium botulinum that block the release of acetylcholine into the synaptic gap of the neuromuscular junction. Their injection near the nerves that supply the target organ selectively and temporarily paralyzes the organ. In particular, the subtype botulinum-A toxin is widely used in neurology to release spastic dystonia in adults and children . In urologic disorders, botulinum-A toxin reliably diminishes external sphincter or detrusor overactivity.

Study population

Patients with spastic neurogenic bladder will be diagnosed clinically and urodynamically with preoperative assessment through:

.History. .Examination. .Urine analysis. .Abdominal ultrasound (to assess upper urinary tract and post micturation residual).

.Kidney function tests. .Urodynamic study. The patients will be re evaluated after 3 months post botulinum toxin injection regarding to previous items.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2018 (actual). Primary completion is estimated for Feb 2019, 13 months after the start.

Of 26 observational studies under Urinary Bladder, Neurogenic, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 61. This study's planned 13 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 23, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
