Recognition of factors influencing therapeutic efficacy of transurethral resection of the prostate:a report of 300 cases

Aim To recognize the factors influencing 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 between 16.3 and 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-1,and average urinary flow rate(Qave) was 4.3 ml·s-1.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 31.8g.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 to 32 months.Postoperative average Qmax increased to 16.9 ml·s-1,Qave increased to 10.8 ml·s-1 and RU decreased to 15 ml.Compared with those of preoperation,the differences were statistically significant(P0.01).Conclusions Adequate and clear recognition of the efficacy-influencing factors before,during and after operation can improve the qualities of TURP for the patients with BPH.
