OBJECTIVE To evaluate the efficacy of intermittent percutaneous posterior tibial nerve stimulation (PPTNS) in patients with refractory interstitial cystitis. PATIENTS AND METHODS One man and 13 women (mean age 58.3 years) with suprapubic or perineal pain were enrolled in a prospective open study, in which they had 10 weekly sessions of PPTNS. Their mean duration of symptoms was 8.3 years. All patients were previously diagnosed as having interstitial cystitis according to the National Institute of Diabetes and Digestive and Kidney Diseases criteria. The response to the treatment were assessed using voiding diary, visual analogue scale diary for a pain index, and the Interstitial Cystitis Problem Index (ICPI), O'Leary/Sant Interstitial Cystitis Symptom Index (ICSI) and the 36-item short-form health survey (SF-36) quality-of-life questionnaire. RESULTS Of the 14 patients, 13 completed the 10 weeks of treatment with no complications; 12 continued treatment for a short period after the study. There were no statistically significant changes in pain scores, voiding frequency and volumes, or in the ICPI, ICSI and SF-36 scores. However, there was an improvement in some patients, with one having complete resolution of the pain. CONCLUSION Intermittent PPTNS in patients with refractory interstitial cystitis has no significant clinical effect over 10 weeks of treatment. [source]

Abstract Aims Lower urinary tract dysfunction is often occurs in patients with Parkinson's disease (PD), that is primarily induced by neurogenic detrusor overactivity (NDO) and negatively effect the quality of the patient's life. The aim of this study is to evaluate the acute effects of posterior tibial nerve stimulation (PTNS) on the urodynamic findings in the PD patients with NDO. Methods Thirty-two patients with PD (19 [59.3%] men and 13 [40.6%] women) with NDO were included in the study. Mean age of the patients was 64.2,±,8.7 years (range 44,78). Urodynamic studies before and during PTNS were performed. Electrical stimulation was applied unilaterally from the medial malleolus and posterior to the edge of the tibia by using charge-compensated 200 µsec pulses with a pulse rate of 20 Hz. Mean first involuntary detrusor (1st IDCV) contractions and means maximum cystometric capacity (MCC) before and during PTNS was compared. Results Mean 1st IDCV on standard cystometry was 145.2,±,41.1 (55,265) ml, while it was 244.7,±,51.7 (145,390) ml during PTNS. MCC on standard cystometry was 204.8,±,40.5 (115,320) ml, while it was 301.2,±,51.5 (230,395) ml during stimulation. Mean 1st IDC and mean MCC were significantly improved during PTNS. Conclusions These results have demonstrated the objective acute effect of PTNS on urodynamic parameters. PTNS is acutely effective to suppress detrusor overactivity in PD patients. Neurourol.
