Key Points Botox bladder injections can treat children who have trouble controlling their urine incontinence. Botox injections relax the bladder muscles so it does not contract too frequently, and gives the child more control over when they urinate. Studies show Botox bladder injections are safe, with minor or no complications It takes a few days for the Botox to work.

It lasts for six months. The doctor will run follow-up tests to check the bladder and see if the injections are helping.

Botox: Injecting into the bladder

These include: Neurogenic bladder Idiopathic detrusor overactivity Detrusor sphincter dyssynergia Your child's doctor may suggest Botox injections if medicines or other forms of therapy do not work. What is Botox? What happens during the procedure? Botox bladder injections are a minor procedure. It takes about 30 minutes. Before the procedure, the doctor will give your child a general anesthetic. When your child is asleep, the doctor places a small tube containing a camera cystoscope into your child's bladder.

A thin tube, called the urethra, connects the bladder to the genitals. The surgeon passes the cystoscope through the urethra. The urethra is checked before the injection.

The surgeon then injects a thin needle containing Botox through the cystoscope. Botox is injected into different areas of the bladder wall. This is a day surgery, so your child does not need to stay overnight in the hospital. After your child wakes up and is able to drink fluids, they can go home. Helping your child. How to take care of your child at home after the procedure It takes a few days for the Botox to work.

When to seek medical attention. When to call the doctor Call your doctor if: your child has pain that is not controlled by pain medicines your child has a fever higher than Follow-up care.

Follow-up The effects of the Botox injection last for six months. The doctor may run: an ultrasound to examining the kidneys and bladder renal ultrasound tests that check the bladder while it is filling up. Before starting the tests, a catheter is inserted régime hyperprotéiné nombre de calories zumba the bladder.

The nurse injects a sterile mixture of salt and water normal saline solution through the catheter. As the bladder fills up, the nurse checks its pressure, and how much it can hold and stretch while filling up.

About the treatment. How can Botox help your child control their urine? Our muscles move by releasing certain chemicals. These chemicals tell our muscles to either: squeeze together contract or expand relax We are able to control when we urinate by contracting and relaxing muscles in our bladder.

Are bladder Botox injections safe? Who should not be treated with Botox?

Doctors will not inject Botox if your child: is pregnant is allergic to the medicine has a disorder that causes weakness in the muscles and nerves Myasthenia gravis. Risks of the treatment.

Botox bladder injections: Side effects Doctors are still testing Botox injections for bladder problems in children. These include: An infection in the organs responsible for storing, producing and excreting urine urinary system. This is called a urinary tract infection. It can be treated within a week with antibiotics.

Discomfort when passing urine. In all, 19 studies have been performed. Only three of these were randomized; the remainder were open-label studies. The primary inclusion criterion in these studies generally corresponded to second-line treatment for refractory or intolerably troublesome bladder overactivity or contraindication of anticholinergic drugs. The criteria used to evaluate the efficacy of botulinum toxin in this situation vary considerably from one group to another.

This latter method of leakage quantification must, however, be used with caution, since it has not been validated for urge incontinence. Urodynamic parameters are also used to evaluate the effect of the toxin on bladder function, both in terms of efficacy and safety of use risk of retention. Other urodynamic parameters such as the maximum urinary flow rate and bladder contractility are monitored to detect possible complications of treatment with botulinum toxin.

InSchmid et al. The dose injected avoiding the trigone was U. The absence of clinical and urodynamic improvement was noted in eight patients who initially had compliance disorders. This study had the advantage of being prospective and investigated a large number of patients. Sahai is one of the few authors to have performed a randomized, placebo-controlled study. Botulinum toxin injection into the detrusor: an effective treatment in idiopathic and neurogenic detrusor overactivity?

The results were judged to be excellent i. Five patients felt better after treatment. However, the improvement in urodynamic parameters seen three and six months after treatment was not always statistically significant.

In this study, the use of a rigid fibre-optic endoscope prevented injection into the anterior bladder wall leading to heterogeneous distribution of the toxin within the detrusor and may thus have biased the study results. Efficacy of botulinum toxin A in the treatment of detrusor overactivity incontinence. The urodynamic data reported by Schmid et al.

The treatment remained effective for five to nine months Table 2. Is the bladder a reliable witness for predicting detrusor overactivity?

However, the performance of a urodynamic status check before and after treatment can be justified when seeking to identify patients who are not likely to respond to botulinum toxin treatment or those likely to present side effects and thus require close monitoring. Large-scale, long-term clinical and urodynamic follow-up could help better identify factors that are predictive of the success or failure of botulinum toxin treatment.

In fact, in the absence of a comparative study of patients with or without detrusor overactivity, it is not possible to tell whether this latter factor is predictive of success or failure. Overactivity syndrome can lead to depression, sexual disorders, sleep disorders and absenteeism from work. Hence, it can have a clearly negative impact on quality of life. Kalsi et al. The results were compared with cystometric and voiding diary data. This effect lasted for nine months and then declined.

Grosse et al. No other authors have reported this complication with the doses used in non-neurological patients. A risk of bladder hypocontractility and thus urine retention and the need for self-catheterization has also been reported in the literature [2,18,22,28,33,39].

Sahai et al. Furthermore, the patient inclusion and exclusion criteria in the various studies may also give rise to bias and prevent intertrial comparisons. The studies also differed in terms of the injection sites and the equipment used. Lastly, the toxin dose and dilution also varied from one study to another. Treatment with anticholinergic agents remains the front-line treatment for NNDO.

It must be attempted with a single drug or a combination, in view of the risk of intensifying the side effects. Furthermore, new treatments and novel drugs for modulating urothelial sensitivity are under development. The intradetrusor injection of botulinum toxin A for the symptomatic treatment of NNDO has yielded encouraging preliminary results. Side effects are infrequent and primarily consist of the dose-dependent risk of urine retention.

At present, this therapeutic technique should only be used in clinical research protocols. In fact, many aspects remain to be elucidated, such as the minimal optimal dose and the risk factors for failure or the occurrence of adverse events.

Le retentissement sociopsychologique parfois majeur de cette pathologie justifie une prise en charge thérapeutique adaptée. Dyskra et al. Cela évoque donc un double effet à la fois sur la partie efférente du réflexe mictionnel, mais aussi sur la régulation du message afférent.

Les injections intradétrusoriennes de la toxine botulique sont réalisées en ambulatoire ou en hospitalisation de jour. Les urines doivent être stériles. Les injections sont réalisées dans la partie superficielle du muscle détrusor.

La procédure dure généralement 20 minutes. Les injections ont été décrites initialement en intramusculaire par assimilation aux autres indications dans le muscle strié. Son effet se maintient entre six et neuf mois selon les études.

Au total, 19 études ont été réalisées. Schmid et al. La dose injectée était de U en évitant le trigone. Cinq patients se sont sentis améliorés. Les données urodynamiques ont montré à six semaines pour Schmid et al. Cependant, la réalisation du bilan urodynamique avant et après traitement peut être justifiée pour identifier les patients susceptibles de ne pas répondre au traitement par toxine botulique ou ceux pouvant présenter des effets secondaires et motivant une surveillance étroite.

Il peut avoir de ce fait un impact négatif reconnu sur la qualité de vie. Les résultats ont été comparés aux donnés du catalogue mictionnel et de la cystomanométrie. De même, Schmid et al. Quatre-vingt-dix pour cent des patients ont rapporté une amélioration dans au moins une des catégories du king health questionnaire capacité à travailler, sommeil, participation sociale, accomplissement de taches de la vie quotidienne et effet global sur la vie de tous les jours.

Cet effet a duré neuf mois puis a régressé. Les effets secondaires de la toxine botulique sont rares. Les sites injectés sont également différents entre les études et pour certaines dépendent du matériel utilisé. Il doit être tenté seul ou en association en tenant compte du risque de majoration des effets secondaires.
