前立腺肥大症術後の膿尿正常化遷延因子の分析

Abstract

本症手術例87例において, 手術術式別の膿尿正常化日数はTUR-P(経尿道的前立腺切除)群75.5±46.0日, supra-P(恥骨上式前立腺摘出)群72.7±30.6日, retro-P(恥骨後式前立腺摘出)群69.3±32.7日であり, 各術式間に有意差は認めなかった.また, 膿尿正常化に影響すると考えられる術前・術中・術後の諸因子について検討した結果, 明かな膿尿正常化遷延因子は, 術前糖尿病合併, 術後膿尿, 術前細菌尿, 術後低蛋白症の4項目であり, また, 要因となりうると考えられる因子は, 高齢者, 術前留置症例, 摘出前立腺重量(重群), 術後細菌尿, 術後貧血, 術後合併症の6項目であった

The outcome of postsurgical pyuria in benign prostatic hypertrophy was studied in 87 patients, and the factors that might affect the outcome were determined. No significant differences were found between operation method and duration until normalization of pyuria, which was 75.5 +/- 46.0 days for transurethral resection of the prostate, 72.7 +/- 30.6 days for suprapubic prostatectomy and 69.3 +/- 32.7 days for retropubic prostatectomy. Prognostic factors were statistically analyzed preoperatively, at operation, and postoperatively. The definite prognostic factors were preoperative diabetes mellitus, preoperative pyuria, preoperative bacteriuria, and postoperative hypoproteinemia. The probable prognostic factors were old-age, preoperative indwelling catheters, heavy prostate tissue, postoperative bacteriuria, postoperative anemia and postoperative complications.
