To determine the completeness of transurethral resection of the prostate (TURP).
The prostate volume of 432 patients was measured by transrectal ultrasonography (TRUS) before they underwent a TURP performed by one of three consultant urological surgeons. The prostate tissue collected at resection was weighed, multiplied by 1.2 to compensate for 'shrinkage', and the amount of tissue removed expressed as a percentage of the pre-operative prostate volume determined by TRUS (resection ratio). The patients were categorized into groups based on pre-operative prostate size.
The mean weight of prostate tissue resected was 25.6 g. Resection ratios increased with prostate size, with the largest occurring in prostates of 71-110 g. The surgeon did not resect more than 50% of the gland volume in any group.
This study counters the theory that a complete resection of the prostate is routinely achieved. The endoscopic appearances probably imply a complete resection of the adenoma but a considerable volume of the gland remains. This has important implications for the detection of prostate carcinoma at TURP and for the staging of the disease.
确定经尿道前列腺切除术（TURP）的切除完整性。
432例患者在接受由三位泌尿外科顾问医师之一实施的TURP术前，通过经直肠超声检查（TRUS）测量前列腺体积。将切除时收集的前列腺组织称重，乘以1.2以补偿“收缩”，切除组织量以TRUS测定的术前前列腺体积的百分比表示（切除率）。根据术前前列腺大小将患者分组。
切除的前列腺组织平均重量为25.6克。切除率随前列腺大小增加，在71 - 110克的前列腺中最高。在任何组中，外科医生切除的腺体体积均未超过50%。
本研究反驳了常规可实现前列腺完全切除的理论。内镜表现可能意味着腺瘤已完全切除，但仍有相当体积的腺体残留。这对TURP时前列腺癌的检测及疾病分期具有重要意义。
