To describe medium-term functional results of Transuretral Needle Ablation (TUNA) to treat symptomatic benign prostatic hyperplasia (BPH) refractory to medical treatment.
Materials and method
Patients who completed at least 2 years follow-up after TUNA were systematically offered a reevaluation including: Flowmetry, PSA, symptom score (IPSS), satisfaction index visual analogic scale (VAS) and a treatment impact evaluation with a Likert scale (ranging from much worse to much improved).
From December 2002 to January 2007, 45 patients were treated with TUNA under local regional anaesthesia (prostatic block). Twenty-seven of them were followed-up longer than 24 months (median follow-up 44 months [26–52]). Changes in the selected outcomes were: increase in Q max from 9.5mL/s preoperatively to 9mL/s at 6 month and 11.5mL/s after 2 years; increase in IPSS from 19.3 before TUNA to 16.3 at 6 month and 16.5 after 2 years.
About subjective evaluation, 58% of patient gave a satisfaction VAS ≥6, and the improvement index was greater or equal to +1 in 67% of case.
In this initial monocentric experiment, despite a modest improvement of objective parameters and a 20% of retreatment rate, TUNA give contentment and improvement sensation for 60% of patients who were treated for non-efficiency of medical treatment for benign prostatic hyperplasia.
