Study summary

Long term open label study on safety and durability of the Urgent-SQ tibial implant device for refractory overactive bladder syndrome (OAB).

Read the detailed description

This is a follow-up study of the study by van der Pal et al. (see reference). The Urgent-SQ is an ankle (tibail) implant that is used for on demand electical stimulation that stimulates the tibial nerve for the treatment of overactive bladder syndrome (OAB). The implant is placed via an minimal invasive surgical procedure. The implant can be activated with an external pulse generator.

This study by van de Pal et al. was conducted with the approval of the local Medical Ethical Committee and with a one year systematic follow-up of eight patients. Since then, follow-up up and use of the device was open-label.

This study reports on the long-term (9yrs) the safety and durability of the Urgent-SQ implant in these eight patients.

Parameters evaluated were local pain and discomford at the site of the implant, AE's related to the implant or the use of the implant. Current use of the treatment and effectivity of the treatment.
