Effect of bipolar radiofrequency thermotherapy on benign prostate hyperplasia

Abstract

This study aims to evaluate the safety and efficacy of the new bipolar radiofrequency thermotherapy device (TEMPRO) in treating patients with benign prostate hyperplasia (BPH). Between December 2017 and November 2018, 72 male patients with BPH were included. All patients completed the International Prostate Symptom Score (IPSS) and International Index of Erectile Function‐5 (IIEF‐5) questionnaires. Physical examinations were performed, and prostate volume, prostatic urethral length and post‐voiding residual urine (PVR) were measured using ultrasound. Uroflowmetry was used to calculate the maximum flow rate of urination (Qmax). Bipolar radiofrequency thermotherapy was applied with TEMPRO system containing a 16Fr applicator. All patients were re‐evaluated at 6 months post‐operatively. The mean age of the patients was 63.22 ± 6.68 years. All patients were treated with local anaesthesia, and three patients were unable to complete the procedure. The median (IQR) visual analogue scale score was 1 (0–3) at 6 hr post‐operatively. After 6 months, significant improvements were observed in the IPSS, QoL, Qmax and PVR values of the patients (p < .001 for Qmax, IPSS and QoL; p = .03 for PMR). The success rate of the procedure was similar between patients with prostate volumes <70 and >70 ml. Due to its low rate of complication, the TEMPRO© treatment is effective in treating BPH, especially among aged patients and those with serious symptoms.
