Evaluation of outcome of transurethral needle ablation for treating symptomatic benign prostatic hyperplasia: A...

The aim of this study is to report our 10-year experience with transurethral needle ablation (TUNA) to evaluate its outcome on long-term basis.

A total of 351 patients' records who underwent TUNA procedure for the management of benign prostatic hyperplasia were reviewed. The International Prostate Symptom Score (IPSS) and peak urinary flow rate were evaluated before the procedure, at 3 and 6 months postoperatively, and then yearly for 10 years. For patients complaining of de novo erectile dysfunction, the International Index of Erectile Function-5 was evaluated. Postoperative complications, number of patients who required additional therapeutic modality/other TUNA sessions, or those dropped out during follow-up were all recorded.

Three hundred and fifty-one patients who underwent TUNA with fulfillment of our selection criteria were included in the study. The yearly records of included patients showed that patients' baseline IPSS was significantly improved all over the follow-up years. Similarly, the maximum flow rate of the patients was significantly improved during the next 8 years. About 96.4% of patients who underwent TUNA did not require additional therapeutic modality/other TUNA sessions during the 1^st-year follow-up. However, by 10 years, 26.4% of patients were offered another TUNA session and shifted to either medical therapy or other minimally invasive therapies. Mild hematuria was the most common complication (85.7%). Urinary retention, urethral stricture, and de novo erectile dysfunction were developed in 15.1%, 1.7%, and 6.8% of patients, respectively. There were no cases of retrograde ejaculation.

TUNA can be considered as a relatively effective technique with a good safety profile. The current study demonstrated both significant subjective and objective improvements over 10 and 8 years of follow-up, respectively. It can be considered as a preferable option for patients who prefer surgical option with preservation of their sexual function and fertility.
