The treatment of small recurrences of bladder tumor by photocoagulation with Ho:YAG laser is a well-tolerated technique that offers an acceptable level of cancer control and a lower cost compared with transurethral resection.

Objective: Overactive bladder is a disease with a high prevalence. The management is difficult, because different demographic, social or economic aspects converge. Our objective was to evaluate the efficacy and satisfaction in patients with overactive bladder treated with transcutaneous electrostimulation of the posterior tibial nerve. Methods: This was a prospective and descriptive study of 45 patients with overactive bladder (with or without detrusor overactivity) resistant to pharmacological treatment. Patients received a weekly session for 12 weeks, with a duration of 30 minutes for each of the sessions. There was a screening after 12 sessions, after which if there had been no response, treatment was suspended and maintenance sessions were not continued (six twice-monthly sessions and three monthly sessions). It was considered that the treatment had been effective when it was possible to decrease the number of events, except the maximum voiding volume, the objective of which was to increase. The results were evaluated using a 3-day voiding diary, an overactive bladder short form questionnaire and a satisfaction level questionnaire. Statistical analysis was performed using IBM SPSS Statistics version 19.0. Independent variables with a normal distribution were examined using the t-test. The Wilcoxon signed-rank test was used to compare the averages of the quantitative variables without a normal distribution. Satisfaction was analysed by a binary and ordinal regression analysis, univariate and multivariate. A P value less than 0.05 was considered statistically significant. Results: All the parameters of the study improved to a statistically relevant degree: frequency, nocturia, urgency, maximum voided volume, urge urinary incontinence. The overactive bladder short form questionnaire score improved but was not statistically significant. Conclusions: The use of transcutaneous electrostimulation of the posterior tibial nerve is a safe, effective and minimally invasive alternative in the treatment of overactive bladder when pharmacological treatment has failed. Patients had a good objective and subjective response in our study.
