经直肠B超测量前列腺体积与TURP手术的相关性研究

Correlation of transrectal ultrasound measurements of prostate volume with transurethral resection of the prostate

目的 :探讨良性前列腺增生 (BPH)患者前列腺总体积 (PV)及移行区体积 (TZV)与TURP手术时间、术中失血量、切除前列腺组织重量间的相互关系。方法 :采用经直肠超声 (TRUS)测定 88例BPH患者PV及TZV ,并分别与手术指标及切除标本进行相关回归分析。结果 :TZV与手术时间 ( r=0 .874,P <0 .0 1)、术中失血量 (r =0 .915 ,P <0 .0 1)、切除组织重量 (r =0 .966,P <0 .0 1,误差 =9.9% )均显著相关 ,PV与切除组织重量也有显著相关 ,但误差达 5 5 .9%。TZV≥ 3 0ml者较TZV <3 0ml者手术时间明显延长、术中失血量增加、TURS先兆发生率增高 (P <0 .0 1)。结论 :TRUS可准确估计PV及TZV ;

Purpose:To assess the correlation of total prostatic volume(PV) and prostate transition zone volume(TZV) with various measurements of blood loss, resected prostatic tissue weight, operation time in patients operated upon with transurethral resection of the prostate (TURP)because of presumed benign prostatic hyperplasia(BPH). Methods:we evaluated 88 BPH cases undergoing TURP according to the resected tissue, the blood loss, the operation time and the transrectal ultrasound (TRUS) volume determinations of the entire prostate or transition prostate zone.Results:TZV correlated well with the operation time (r= 0.874 ,P< 0.01 ), the blood loss (r< 0.915 ,P< 0.01 ) and the resected weight (r= 0.966 ,P< 0.01 , the error= 9.9 %). PV also significantly correlated with the resected weight, but the error was 55.9 %. Patients with TZV 30ml or greater need a longer mean operation time and have greater mean blood loss and a higher rate of TURS (P< 0.01 ) than those with smaller PZV.Conclusions:TRUS accurately estimated the PV and TVZ. The assessment of pre-operation TZV seems to be a powerful index for BPH diagnosis.
