[Tuna: clinical retrospective study addressing mid-term outcomes].

PURPOSE

To estimate the efficiency and morbidity of the radiofrequency (Tuna) for treatment of symptomatic benign prostatic hyperplasia (BPH) in patients with medical treatment failure.

MATERIAL AND METHODS

Between September 2003 and July 2007, 31 patients, mean age 59,5 years (50-76), were treated for BPH with Tuna. Patients had initially received medical treatment, which happened to fail and Tuna was offered as surgical treatment. Available clinical data of 28 patients was retrospectively analyzed. Mictionnel status was estimated with International Prostatic Symptoms Score (IPSS), urinary peak flow (UPF) and post void residual urine (PVR). Quality of life issues were also addressed. Efficiency of treatment was estimated on the evolution of these parameters after an average follow-up of 20 months (5-47). To estimate morbidity of treatment, peroperative and late complications were assessed.

RESULTS

Twenty-eight patients were included in the study. At a mean follow-up of 20 months, a significant improvement of the mictionnel status was found for the IPSS, the quality of life, the Qmax (p<0,001) and the PVR (p<0,005) and quality of life. Morbidity was verified as minimal in the series. At a follow-up period of 20 months, 15 patients (53,6%) had stopped medical treatment, 10 patients (35,7%) pursued medical treatment and three patients (10,7%) had undergone another type of surgical treatment for BPH. The rate of re-treatment in the series was 46,4%. Among the group of patients without any medical treatment (15 patients), 10 patients reported satisfactory quality of life.

CONCLUSION

Tuna is a technique with significant good results for the treatment of LUTS-BPH. The main advantage of this technique is its low morbidity, however, the rate of retreatment was observed as high. Series of patients with long-term follow-up should provide evidence to objectively define the role of Tuna in BPH surgical treatment.
