TPTNS for Treating Patients With Premature Ejaculation

Not Applicable

Completed

Brief Summary: Background: Transcutaneous posterior tibial nerve stimulation is an effective therapy for controlling urinary incontinence. Premature ejaculation (PE) and urinary incontinence are anatomically and physio-pathologically similar. Based on this, the use of this therapy is considered to be viable for the control of PE.

Objective: To evaluate the efficacy of transcutaneous posterior tibial nerve electrostimulation for the ejaculatory reflex.

Patients and Methods: Phase II clinical trial. Patients with a diagnosis of premature ejaculation who are treated at the Colombia Boston Medical Group clinic will be included. The participants will receive 3 transcutaneous posterior tibial nerve stimulation therapies per week for 12 weeks. The IELT (Intravaginal ejaculatory latency time) and the PEDT (Premature Ejaculatory Diagnosis Tool) scale will be evaluated on week 6, at the end of treatment, and three months after completing the protocol.

Primary Outcome Measures

Name	Time	Method
Clinical Improvement	Three months after completion.	Number of patients with clinical improvement of premature ejaculation, defined as a tripling of the baseline time (without treatment), as measured by the IELT (intravaginal ejaculation latency time)

Secondary Outcome Measures

Name	Time	Method
Change in the Basal PDET Score	Three months after completion.	The premature ejaculation diagnostic tool (PEDT), is a questionnaire for the diagnosis of premature ejaculation. The questionnaire has 5 questions and each of them scores from 0 to 4. The score is the sum of all the answers (range 0-20), with higher scores suggesting more difficulties with premature ejaculation. A score ≥11 points suggested the presence of premature ejaculation. This outcome indicates the number of patients who decrease their initial PEDT score after 3 months after completing treatment.
Magnitude of the Change in the PEDT Score	Three months after completion.	The premature ejaculation diagnostic tool (PEDT), is a questionnaire for the diagnosis of premature ejaculation. The questionnaire has 5 questions and each of them scores from 0 to 4. The score is the sum of all the answers (range 0-20), with higher scores suggesting more difficulties with premature ejaculation. A score ≥11 points suggested the presence of premature ejaculation. This outcome indicates the average change that patients had in their PEDT score at baseline, 3 months after completing treatment.
Frequency of Adverse Events	up to 6 months	Number of patients with adverse events or side effects with the therapy
