| To evaluate the prostate volume removal rate of 160 W high power green-light laser vaporization and 2μm laser vaporization in the treatment of benign prostatic hyperplasia.Methods: From January 2014 to September 2015 a total of 100 cases of BPH patients required surgical intervention were admitted from the department of urology of the Second Affiliated Hospital of Soochow University. They were divided into two groups by different operation method(2μm VRP and PVP).The significant markers and the therapeutic results were recorded and analyzed, including such as prostatic volume, maximal urinary flow rate(Qmax),residual urine volume(RUV) of the patients Pre- and 3months to 2 years post-operation.ResultsAll the operations were performed successfully. There was no significant difference of the age, volumes of prostates, Qmax and RUV between the two group(P>0.05). In PVP group, the mean reduce amount of prostate was 50.0±26.9ml, and which in 2μm was42.6±23.4ml,there was no significant difference in it. But, the mean prostatic volume removal rate was 54.3±17.0% in PVP group, while it was 43.9±14.5% in 2μm group, there was statistically significant difference of the prostatic volume removal rate. The reduce of hemoglobin was 13.8±14.1g/L in PVP group while 6.7±14.4 in 2μm group(P < 0.05).Qmax, RUV and prostatic volume before operation were all significantly different from those obtained 3months to 2 years after it(P<0.01) in both of two groups, but none of the indexes exhibited statistically significant differences when compared in the same period(P>0.05).ConclusionsBoth the two operation methods are safe and efficient procedure for the treatment ofBPH. The curative effect is similar to each other, they are all the ideal choice of the minimally invasive treatment of benign prostatic hyperplasia. To compare with 2μm laser vaporization, 160 W high power green-light laser vaporization had a better effect of prostate volume removal rate but 2μm laser vaporization was better in stop bleeding. |
