To study whether transrectal ultrasound (TRUS) volume determinations of the whole prostate and of the adenomas alone correlate to resected weight, operation time and blood loss in patients operated upon with transurethral resection of the prostate because of presumed benign prostatic hyperplasia (BPH).
The whole prostate and the transition zone, which corresponds to the adenomas, were measured separately in 159 patients with presumed BPH, pre-operatively and 4 months post-operatively.
The transition zone volume correlated well with the resected weight (r = 0.91; P < 0.0001), the blood loss (r = 0.67; P < 0.0001) and the operation time (r = 0.67; P < 0.0001). Four months post-operatively a reduction of the total prostate volume was recorded which corresponded well with the resected weight (r = 0.91; P < 0.0001).
TRUS with high resolution 7 MHz probes successfully estimated the size of the whole prostate and that of the adenomas alone. The transition zone volume predicted the expected resection weight of adenomas and to some extent the duration of the operation and the blood loss. These calculations may be used for more accurate pre-operative planning. Together with its superior detection rate for prostate cancer, TRUS seems to be a powerful tool in the pre-operative morphological assessment of patients with prostatism.
研究对于因疑似良性前列腺增生（BPH）而接受经尿道前列腺切除术的患者，经直肠超声（TRUS）测定的整个前列腺体积以及单独腺瘤的体积与切除重量、手术时间和失血量之间是否相关。
对159例疑似BPH患者在术前及术后4个月分别测量整个前列腺以及与腺瘤对应的移行区。
移行区体积与切除重量（r = 0.91；P < 0.0001）、失血量（r = 0.67；P < 0.0001）及手术时间（r = 0.67；P < 0.0001）显著相关。术后4个月记录到前列腺总体积减小，这与切除重量显著相关（r = 0.91；P < 0.0001）。
使用高分辨率7MHz探头的TRUS成功估算了整个前列腺及单独腺瘤的大小。移行区体积可预测腺瘤的预期切除重量，并在一定程度上预测手术持续时间和失血量。这些计算可用于更准确的术前规划。连同其对前列腺癌的较高检出率，TRUS似乎是对前列腺增生患者进行术前形态学评估的有力工具。
