A Comparative Study Of 2μm Laser Vaporization And Resection Of The Prostate, Greenlight Photoselective Vaporization Of The Prostate And Transurethral Resection Of The Prostate For BPH

To evaluate the short-term efficacy of 2μm laser vaporization and resection of the prostate (2μm VRP), Greenlight photoselective vaporization of the prostate (PVP) and transurethral resection of the prostate(TURP) in the treatment of benign porstatic hyperplasia(BPH),and compare the efficacy with transuerthral resection of the prostate (BPH)MethodA total of 482 patients who were diagnosed with BPH from March 2009 to April 2010 in 4th affiliated hosptal of CMU were divided into three groups according to the volumes of prostate,and then each group were divided into three randomly, underwent 2μm VRP and PVP and TURP.The singificant markers and therapeutic results were recorded and analyzed, which includes such as the operating time, haemoglobin,catheterization time, the length of hospital stay after operation, IPSS,QOLS,Qmxa at the third month postoperatively. The short-term therapeutic effects were compared between the three operations in the different volumes of prostate. ResultThere was no significant difference of preoperative factors and the volumes of prostates between the three group (P>0.05).In the group the volumes of prostate less then 50cm3,The operating time of 2μm VRP was 43.2±4.3 min,there was significant differences with the other two groups; In the group the volumes of prostate between 50 and 90cm3, The operating time of 2μm VRP was 58.7±5.1 min, there was differences with the other two groups; In the group the volumes of prostate more then 90cm3, The operating time of 2μm VRP was 81.2±5.1 min,that of PVP was 112.6±7.2 min,and that of TURP was 95.8±6.9 min,there was differences between the three operations. Remarkable differences were found in haemoglobin,length of hospital stay after operation,catheterization time (P<0.05). IPSS, Qmax and QOLS before operation were significantly different from those obtained 3 months after it (P< 0.05) in the groups,but none of the indexes exhibited statistically significant differences when compared in the same period (P>0.05)Conclusions2μm VRP is a safe and efficient procedure for the treatment of BPH,with less blood loss, needs short postoperative reovery time.The operating time is long,but it slowly increase with the volume of prostate increasing. And it has advantages when the patients have large prostates.Although it is more difficult for doctors to learn this technology,but it should be performed extensively when we do more.PVP is a safe and efficient procedure for the treatment of BPH too, with advantages of less blood loss and better tolerance. And it has advantages when the patients are high age.The operating time is short,but it quickly increase with the volume of prostate increasing.
