経尿道的前立腺切除術後の膿尿持続期間

Abstract

過去10年間にTURPを施行した273例のBPH患者について, TURP後の膿尿持続期間及びそれに影響を及ぼす因子についてretrospectiveに検討を加えた. 1)273例の前立腺切除重量の平均±SDは13.2±10.2g(1～52g), 手術時間は74.3±29.8分(25～215分), 切除重量/手術時間は0.172±0.093g/分(0.018～0.500g/分), 術後膿尿持続期間は110.6±38.3日(23～273日)であった. 2)患者の年齢, 切除重量, 手術時間, 切除重量/手術時間の全てにおいてTURP後の膿尿持続期間と有意な正の相関が認められたが, 切除重量が最も大きな影響を及ぼしていた. 3)術者, 術後使用抗菌剤の種類及び術前の膿尿の有無は術後膿尿持続期間に有意な影響を示さなかった. 4)10g毎の切除重量別に分けての検討により, 特に切除重量が20g台のBPHに対しては手術の早さが術後膿尿持続期間の短縮に重要であることが示唆された

A retrospective study was conducted on the duration of pyuria after transurethral resection of the prostate (TURP) and the factors affecting the duration in 273 patients, who were diagnosed as having benign prostatic hyperplasia (BPH) with postoperative resolution of pyuria among those who underwent TURP over the last ten years at our clinic. In the 273 patients, the mean (+/- SD) weight of the resected prostate was 13.2 +/- 10.2 g (range : 1-52 g), the mean operating time was 74.3 +/- 29.8 min (25-215 min), the duration of pyuria was 110.6 +/- 38.3 days (23-273 days), and the resected weight to operating time ratio was 0.172 +/- 0.093 g/min (0.018-0.500 g/min). There was a significant correlation between the duration of pyuria and the patient's age, resected weight, operating time, or resected weight/operating time ratio, resected weight being the most important factor. The surgeon, the postoperative antibiotics used, and the preoperative existence of pyuria did not have any significant effect on the duration of postoperative pyuria. Investigation after stratification by the resected weight in 10 g increments suggested that a shorter operating time was important to reduce the duration of postoperative pyuria, particularly in BPH patients with a resected weight of 20-29 g.
