[Transurethral needle ablation (TUNA) of the prostate: preliminary results].

: A multicentric prospective study was designed in Italy to verify the efficacy and the safety of TUNA-BPH patients treatment. The study is co-ordinate by Progress in Urology Association was started in January 1994. Thirty five patients were treated (Mean age 68.4 +/- 4.1 aa). All patients were selected and evaluated to respect the recommendations of the International Consensus Committee (Paris 1993). The procedure was performed with lidocaine 2.5% urethral gel, oral intake of 10 mg of diazepam and steroidal antiphlogistic drugs 1 hour before treatment. Maximal number of prostatic lesions were 6; in 2 BPH initial cases were done 2 lesions alone. The treatment was interrupted at the third lesion in 2 patients because uncomfortable. Hematuria was observed in all patients, but it was resolved within 12 hours. Irritative symptoms were referred by 10 patients (28.6%) and they spontaneously were insignificant within 24 hours. One patient had an acute prostatitis. In 15 patients (42.6%) was necessary to put a suprapubic cystostomy, but all except one voided within 36 hours. We noted narrow connection between prostatic lesions number and urinary acute retention after TUNA. The average follow-up is 3.2 months (range 0.5-6). At the follow-up urine culture was always negative and PSA values increased in the first month. The value of PSA was always higher than pre-treatment, but from 1 month to 3 months progressively reduced.(ABSTRACT TRUNCATED AT 250 WORDS)
