Material and Methods: 103 patients attending our clinic due to BPO and related complaints with high ASA score had outcomes after the procedure recorded prospectively and investigated retrospectively. Qmax, prostate volume, IPSS score, quality of life score, and presence of catheters were recorded before the procedure and analyzed with the outcomes after the procedure. Results: The ASA scores were calculated as 3.0 ± 1.0 (IQR). Before the procedure, Qmax values (mean (SD)) were 5.11 ± 5.37 ml/s, while in the 6th month after the procedure Qmax values were identified as 10.45 ± 3.8 ml/s (p < 0.001). Of 53 patients (55.2%) with chronic catheters who could not be operated, 30 (61.2%) no longer required urinary catheter. Conclusion: Bipolar RF thermotherapy appears to be an effective method for patients with BPO who cannot be operated. Due to the surgical risks of patients dependent on the catheter in spite of receiving medical treatment, it is a good alternative to remove catheter dependence. It may be one of the methods that should be remembered, especially in this patient group.
