Disappointed by the approximate assessment of prostate size given by traditional methods (rectal examination, endovesical filling defect produced by the hypertrophic organ in the secretory cystogram, length of the prostatic urethra by micturating urethrography), the authors carried out a prospective study in 100 patients undergoing surgery for benign prostatic hypertrophy which compared traditional data with those provided by transabdominal prostatic echography and the measurement of urethral manometric profile. Determination of the maximum dimensions of the adenoma was used to calculate its volume and weight. Ultrasound studies gave the most accurate information : 95% correct results. This was followed by the measurement of urethral profile with 81% of accurate results (but this is an instrumental procedure which has certain disadvantages). Radiology takes 3rd place, with 59% accurate results and rectal examination immediately after with 58%.
由于传统方法（直肠指检、分泌性膀胱造影中肥大器官造成的膀胱内充盈缺损、排尿性尿道造影测量前列腺尿道长度）对前列腺大小的评估不够准确，作者对100例接受良性前列腺增生手术的患者进行了一项前瞻性研究，将传统数据与经腹前列腺超声检查及尿道测压曲线测量所提供的数据进行比较。通过测定腺瘤的最大尺寸来计算其体积和重量。超声检查提供的信息最准确：正确结果达95%。其次是尿道轮廓测量，准确结果为81%（但这是一种有一定缺点的器械检查方法）。放射学位列第三，准确结果为59%，紧随其后的直肠指检准确率为58%。
