Percutaneous tibial nerve stimulation in treatment of overactive bladder: When should retreatment be started? - Abstract

Servicio de Urología del Hospital Universitario "Virgen de la Victoria," Málaga, España.

 

To study the response to posterior tibial nerve stimulation in patients with overactive bladder refractory to medical treatment.

A cohort of 53 patients were treated by posterior tibial nerve stimulation and followed up for a maximum of 24 months. All patients completed the International Consultation on Incontinence Modular Questionnaire-Short Form quality of life questionnaire and kept a urination diary to record the daytime urination frequency and night-time urination frequency. Urodynamic studies were also conducted.

At 6 months of follow-up, a cure/improvement rate of 92.4% (49 of 53 cases) had been achieved. Ten patients were given additional treatment and were excluded from subsequent follow-up analysis. At 12 months of follow-up, a cure/improvement rate of 91.69% had been achieved (39 of 43). At 24 months of follow-up, of the 16 patients initially included during the first year, a cure/improvement rate of 62.5% had been achieved (10 of 16). The first sensation of bladder filling had increased by the end of treatment, with differences observed before and after posterior tibial nerve stimulation (P ≤ .001). The average post-treatment bladder capacity had increased by 72.7 mL compared with the initial value (P ≤ .001). At 24 months of follow-up, the group of 16 patients evaluated recorded a significant worsening of night-time urination frequency (P ≤ .05) and quality of life (P ≤ .01).

Posterior tibial nerve stimulation is a good option for the treatment of overactive bladder. In our series, the optimal point to start retreatment would be at 24 months after therapy completion.
