OBJECTIVE: To determine the effect of a pause in percutaneous tibial nerve stimulation (PTNS) in successfully treated patients with an overactive bladder (OAB), and the reproducibility of successful treatment when restored. PATIENTS AND METHODS: Eleven patients (mean age 51 years) with refractory OAB (more than seven voids and/or three or more urge incontinence episodes per day) were successfully treated with PTNS, and then discontinued treatment. Patients completed bladder diaries and quality-of-life (QoL) questionnaires (Short Form-36 and I-QoL) before (T1) and after a 6-week pause (T2) of maintenance PTNS, and again after re-treatment (T3). The first objective was defined as a > or = 50% increase in the incontinence episodes and/or voiding frequency in the bladder diary after T2. The second objective was defined as > or = 50% fewer incontinence episodes and/or voiding frequency in bladder diary after T3. RESULTS: At T2, seven of the 11 patients had a > or = 50% increase in incontinence episodes and/or voiding frequency in the bladder diary. The mean voided volume, nocturia, number of incontinence episodes and incontinence severity deteriorated significantly (P < 0.05). At T3, nine patients had > or = 50% fewer incontinence episodes and/or voiding frequency in the bladder diary. Nocturia, the number of incontinence episodes, incontinence severity, mean voided volume and quality of life improved significantly (P < 0.05). CONCLUSIONS: Continuous therapy is necessary in patients with OAB treated successfully by PTNS. The efficacy of PTNS can be reproduced in patients formerly treated successfully.
