[Study on the duration of pyuria after transurethral resection of prostate].
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.
