E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the non-inferiority of “antibiotic saving strategy” compared to
peri-operative antibiotic strategy (current recommendations) for occurrence of symptomatic UTI after intra-vesical BoNTA injections in the management of asymptomatic bacteriuria (AB) among multiple sclerosis (MS) and spinal cord injured (SCI) patients undergoing clean intermittent self-catheterization (CISC).
|
|
E.2.2 | Secondary objectives of the trial |
In the management of AB in the context of intra-vesical BoNTA injections, in MS and SCI patients undergoing CISC:
- To compare between antibiotic saving strategy and peri-operative antibiotic strategy the others safety and efficacy outcomes.
- To study the risk factors associated with post-injection symptomatic UTI.
- To carry out an ad-hoc health-economic analysis aiming to compare current recommendations (peri-operative antibiotic strategy) with the “antibiotic saving strategy”.

|
E.5.2 | Secondary end point(s) |
Safety:
-Rate of patients with febrile symptomatic UTI occurring within the 6 weeks following BoNTA injections.
-Rate of patients with non-febrile symptomatic UTI occurring within the 6 weeks following BoNTA injections.
-Rate of patients with symptomatic UTI within the 6 weeks following BoNTA injections finally needing the administration of an antibiotic therapy.
-Rate of patients with complication (other than symptomatic UTI) related to BoNTA injections occurring within the 6 weeks following the injections.
-Rate of patients with complication not related to BoNTA injections occurring within the 6 weeks following the injections.
-Rate of patients with admission to an emergency unit related to BoNTA injections occurring within the 6 weeks following the injections.
-Rate of patients with admission to an emergency unit not related to BoNTA occurring within the 6 weeks following the injections.
-Rate of patients with admission in a non-scheduled hospitalization related to BoNTA injections occurring within the 6 weeks following the injections.
-Rate of patients with admission in a non-scheduled hospitalization not related to BoNTA injections occurring within the 6 weeks following the injections.
Efficacy:
-Maximal cystometric capacity (MCC) evaluated 6 weeks after BoNTA injections.
-Rate of patients with DO (non-voiding detrusor contractions during feeling phase) evaluated 6 weeks after BoNTA injections.

-Frequency of CISC in the 3 days following BoNTA injections
-Daily diuresis in the 3 days following BoNTA injections
-Functional bladder capacity in the 3 days following BoNTA injections
-Duration of the disease (MS or SCI)
