Clinical analysis of transurethral electrovaporization of the prostate report of 260 cases

Objective To investigate the factors which may influente the therapeutic efficacy of transurethral electrovaporization of the prostate.Methods The clinical data of 260 patients with benign prostatic hyperplasia(BPH) were retrospectively reviewed based on the mastering of TUVP.The patients'age ranged from 52～86 years,with a mean of 66.8 years.Preoperatively,the volume of the prostate was 20.6～116 ml,with a mean of 52.4 ml,measured by B-ultrasound.The averagemaximum urinary flow rate(Qmax) was 7.8 ml/s,and the average of urinary flow rate(Qave) was 3.8 ml/s.The average of residual urinary volume(RUV) was 96ml,and the average of IPSS was 23.Results TUVP was successfully performed on the 258 patients.The average resected prostate tissue weight was 35.8 g.The average electric ablation time was 56 minutes.Intraoperative blood transfusion was performed in 5 cases.Two cases were underwent conversion to an open surgery.Aura of transurethral resection syndrome(TURS) occurred in 4 cases,but no TURS occurred.Of the 225,225 cases(86.5%) were followed up for 1～36 months.Postoperative average Qmax increased to 17.5 ml/s,Qave increased to 8.9 ml/s.and RU decreased to 20 ml, and IPSS to 9.Compared with those of cases of preoperation,the differences were statistically significant(P0.01).Conclusion Adequate and clear recongnition of the efficacy-influencing factors before,during and after operation can improve the qualities of TUVP for the patients with BPH.
