Purpose:

To evaluate The safety and efficacy of greenlight laser (XPS) for the treatment of prostate beyond 100gm

Materials and Methods:

We recruited 40 patients all with extreme large prostate (volume above 100g) measured by transrectal ultrasound (TRUS) and conduct a retrospective study in one medical center. All the patients recieved 180-W XPS™ GreenLight laser prostatectomy by one single experienced surgeon. We recorded patients’ IPSS score, prostate volume, uroflow study, post void volume (PVR), as well as PSA before operation and after operation.

Results:

After vaporized prostatectomy by greenlight laser (XPS), the result showed: decreasing prostate volume (before XPS: 127.1±26.9ml (n=21), after XPS: 41.7±27.2ml, p<0.001), increasing Qmax in uroflow study (before XPS: 5.0±6.4 m/s (n=7), after XPS: 17.7±12.1 m/s, p=0.012), decreasing PVR (before XPS: 190.33±188.1 ml (n=9), after XPS: 142.0±47.5 ml, p=0.021), improvement of IPSS (before XPS: 25.1±5.1(n=22), after XPS: 8.1±5.2, p<0.001), improvement of quality of life (QoL) (before XPS: 5.3±8.3 (n=22), after XPS: 1.5±1.0, p<0.001), and decreasing PSA (before XPS: 13.4±6.4 (n=23), after XPS: 5.9±4.2, p<0.001). No patients need blood transfusion nor TURP syndrome detected after operation.

Conclusions:
