Controversies exist regarding the accuracy of transrectal ultrasound (TRUS) determination of transition zone volume (TZV) when compared with enucleated adenoma weight.
To determine the accuracy and reliability of measurements of the TZV by TRUS, by comparing preoperative radiological findings with the enucleated prostate adenoma volume, measured by fluid displacement volumetry (FDV), after retropubic prostatectomy performed by the Millin method, and, moreover, to evaluate changes in the surgical capsule size in the intermediate postoperative period.
We measured TZV preoperatively using TRUS and postoperatively with FDV in 112 patients who underwent retroperitoneal prostatectomy for benign prostatic hyperplasia (BPH).
The TRUS volume correlated well with specimen volumes (r = 0.945, p < 0.0001). The median (quartile 1, quartile 3) absolute error was 7.35 ml (4.15 ml, 9.28 ml) and the median percent error was 9.12% (4.75%, 14.98%). Percent error, but not absolute error, was significantly related to TRUS TZV (p < 0.001 and 0.217, respectively). Adenomas > 80 cc were associated with lower percent error. The median volume of the residual prostate tissue measured 3.5 years after prostatectomy was 92.65 cc (65.75 cc, 109.58 cc), whereas the median volume of the surgical capsule, depending on the equation used for its calculation, was 24.80 cc (16.25 cc, 37.37 cc) and 31.43 cc (23.14 cc, 43.32 cc).
The TRUS TZV correlated well with values determined by FDV. It can be reliably used in clinical management of BPH.
与摘除的腺瘤重量相比，经直肠超声（TRUS）测定移行区体积（TZV）的准确性存在争议。
通过将术前影像学检查结果与经耻骨后前列腺切除术（采用米林法）后通过液体置换容积法（FDV）测量的摘除前列腺腺瘤体积进行比较，确定TRUS测量TZV的准确性和可靠性，此外，评估术后中期手术包膜大小的变化。
我们对112例因良性前列腺增生（BPH）接受腹膜后前列腺切除术的患者术前使用TRUS测量TZV，术后使用FDV测量。
TRUS体积与标本体积相关性良好（r = 0.945，p < 0.0001）。中位数（四分位数1，四分位数3）绝对误差为7.35毫升（4.15毫升，9.28毫升），中位数百分比误差为9.12%（4.75%，14.98%）。百分比误差而非绝对误差与TRUS TZV显著相关（分别为p < 0.001和0.217）。腺瘤体积> 80立方厘米与较低的百分比误差相关。前列腺切除术后3.5年测量的残余前列腺组织中位数体积为92.65立方厘米（65.75立方厘米，109.58立方厘米），而手术包膜的中位数体积，根据用于计算的公式，分别为24.80立方厘米（16.25立方厘米，37.37立方厘米）和31.43立方厘米（23.14立方厘米，43.32立方厘米）。
TRUS TZV与FDV测定值相关性良好。它可可靠地用于BPH的临床管理。
