経尿道的切除術後の性機能障害の検討

Sexual dysfunction after transurethral resection

　経尿道的切除術を受けた男性77症例を対象に，術前および術後2か月目と6か月目にIIEF5を中心とした性機能アンケート調査を行った。対象の平均年齢は73.3歳で，術前に性生活があった症例は13例（17％）であった。TUR-Pの39症例およびTUR-Btの38症例のいずれにおいても，術前後のIIEF5に変化は認められなかった。術前IIEF5が5点以上であった症例に限れば，TUR-Btの14症例では術前後でIIEF5に変化はなかったものの，TUR-Pの16症例では14.6±5.5から2か月目11.3±8.7，6か月目14.4±7.4と，2か月目に有意な低下（p＝0.03）が認められた。TUR-P後に一時的に性機能障害が生じる可能性が示唆された。

　The sexual activity was prospectively assessed in patients who underwent TUR-P or TUR-Bt between January 2006 and March 2007. We evaluated sexual function of patients using questionnaires including the International Index of Erectile Function Instrument（IIEF5）. The questionnaire was performed before surgery, and 2 and 6 months after surgery. Seventy-seven patients（TUR-P：39, TUR-Bt：38）were enrolled in the survey. The mean age was 73.3 years. Before surgery, 17％ of the patients were active in sexuality and the mean IIEF5 was 5.8. IIEF5 did not demonstrate significant changes after TUR-P and TUR-Bt. However the patients with IIEF5 over 5 before surgery, showed a significant decrease at 2 months after TUR-P（p＝0.03）, while no significant change was observed after TUR-Bt. From our study it was suggested that TUR-P provides some influence on sexual function.
