前立腺肥大症に対する経尿道的温熱療法の臨床成績

Abstract

30例のBPHについて経尿道的温熱療法装置の有効性, 安全性, 有用性および臨床成績を評価した。自覚症状は70%に改善がみられ, 尿流量検査や残尿量の面で他覚的所見には71%に改善が見られた

Transurethral hyperthermic treatment was performed on 30 patients with benign prostatic hypertrophy (BPH). Two patients had a urethral catheter because of urinary retention. The prostate was heated transurethrally. The treatment consisted of 3-8 sessions of 60 min. each. To evaluate this treatment, the following parameters were determined before and 1-5 weeks after the last hyperthermia session; subjective symptoms score, and as objective data residual urine volume and uroflowmetry. The symptoms score improved in 25 (83%) patients. Of 2 patients with a catheter, the catheter could be removed from 1 patient. Although there was no change in prostatic volume, significant decreases in residual urine volume, and increases of maximum flow rate and mean flow rate were observed. No adverse reactions were seen. Judging from the above results, this treatment is considered to be useful for patients with BPH.
