Recognition of factors influencing therapeutic efficacy of transurethral resection of the prostate (report of 600 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To recognize the factors which influence the therapeutic efficacy of transurethral resection of the prostate (TURP) and to improve the qualities of TURP. Methods The data of 600 patients with benign prostatic hyperplasia (BPH) were retrospectively studied based on the mastering of TURP.The patients’age ranged from 52 to 92 years,with a mean of 64.8 years.Preoperatively,the volume of the prostate was 16.3～210.4 ml,with a mean of 46.2 ml,measured by color Doppler B-ultrasound.The average maximum urinary flow rate (Qmax) was 8.4 ml/s,and average urinary flow rate (Qave) was 4.3 ml/s.The average residual urinary volume (RU) was 75 ml,and the average IPSS was 23. Results TURP was successfully performed on all the 600 patients.The average resected prostate tissue weight was 31.8 g.The average electric ablation time was 51 minutes.Intraoperative blood transfusion was performed in 38 cases. Aura of transurethral resection syndrome (TURS) occurred in 4 cases,but no TURS occurred.Of the 600 cases,508 cases (85%) were followed up for 1～32 months.Postoperative average Qmax increased to 16.9 ml/s,Qave increased to 10.8 ml/s and RU decreased to 15 ml.Compared with those of preoperation,the differences were statistically significant (P
