TUR-P後の膿尿の経過とその期間に関する因子の分析

Abstract

76症例についての術後の膿尿期間は, 70.1±24.1日であった.重要な因子は, 第一に切除重量(レインジ42.8), 第二に術後感染(レインジ23.9), 第三に術前感染(レインジ20.9)であった

The course of pyuria and bacteriuria was reviewed in 54 patients undergoing transurethral resection of prostate. Pyuria, which was seen in all cases, lasted for 70.1 +/- 24.7 days and bacteriuria defined as more than 10(4)/ml occurred in 16 patients (30%) postoperatively. To analyze the factors affecting the duration of pyuria, we utilized Hayashi's multidimensional quantification I theory. The factors included age, serum protein, preoperative indwelling catheter, preoperative urinary tract infection, resected weight, postoperative infection, the duration of postoperative indwelling catheter, and the way of antibacterial prophylaxis. The most important factor was resected weight (range 42.8 days), the second was postoperative infection (range 23.9 days) and the third preoperative infection (range 20.9 days). The other factors had no significance. Our analysis showed good correlation between the observed and predicted duration of pyuria (r = 0.82, p less than 0.005).
