Clinical Interest of the Temporary Urethral Stent Allium " Bulbar Urethral Stent " in the Treatment of Detrusor Sphincter Dyssynergia

Detrusor striated sphincter dyssynergia (DSSD) is defined as the persistence or increasing of the striated sphincter activity during voiding and characterizes the spinal cord injuries located under the protuberance. The standard treatment for DSSD is medical, either pharmacological or by clean intermittent self-catheterisation (CISC). Some patients are unable to perform CISC and require alternative surgical techniques such as external sphincterotomy which is invasive, irreversible and with no adjustment period for the patient.

Urethral stents have been developed as an alternative to surgical sphincterotomy. Temporary stents provide a non-definitive treatment, especially for evolutionary pathologies, for patients refusing a destructive surgery (psychosocial impact), or for patients having not defined yet their therapeutic preference. The Allium company has developed the " Bulbar Urethral Stent " (BUS) system, which advantages are the possibility to perform the procedure under local anesthesia and to remove more easily the stent, with similar performances compared to the other devices. In order to quantify the interest of the BUS system, the investigators propose to perform a prospective study aimed at describing its technical and clinical results in terms of efficacy and safety.
