Abstract:
Objective To evaluate the impact factors on weight and proportion of prostate tissue resected by transurethral resection of prostate (TURP) in patients with benign prostatic hyperplasia (BPH). Methods The patients undergoing TURP from January 2007 to June 2009 and diagnosed as BPH according to postoperative pathological results were enrolled in this study. The prostate volume measured by transrectal ultrasound (TRUS), prostate specific antigen (PSA), maximum flow rate (MFR), residual urine volume and body mass index (BMI) were measured and calculated. The prostate tissue collected at resection was weighed, and the proportion of the prostate resected was the percentage of the pre-operative estimated weight. Results For the 458 patients with the average age of 69.5 years, average BMI was 24. 3 kg/m2 , PSA 6. 1 μg/ml, prostate volume 85.5 ml, MFR 8. 4ml/s, residual urine volume 31.8 ml, resected prostate weight 32.9 g, proportion of resection 37. 6%Prostate volume and BMI were positively related with resected prostate weight. BMI was positively related with proportion of prostate resection. There was no linear correlation between prostate volume and resected proportion. But there was significant difference in resected proportion between patients with prostate volume more than and less than 40 ml. Finasteride had no influence on the weight and resected proportion. Conclusions Prostate volume, PSA and BMI are correlated with weight and proportion of prostate tissue resected by TURP. Finasteride has no influence on the resected weight and proportion.
