ABSTRACT
BACKGROUND/PURPOSE:
To evaluate the effectiveness and safety of high-power 120W Greenlight HPS laser (HPS) and compare the results to transurethral resection of the prostate (TURP), and define a subgroup of patients who had better symptom score improvement after HPS.METHODS:
One hundred and twenty-five patients who underwent surgery for benign prostatic hyperplasia (BPH) (61 HPS and 64 TURP) were retrospectively followed. Improvements of International Prostate Symptom Score (IPSS), quality of life score (QoL), maximum flow rate (Qmax) and post-void residual (PVR) were assessed at 4 weeks after the procedures. Potential covariates including age, body mass index (BMI), prostate volume (PV) and serum prostate-specific antigen (PSA) were defined and further subgroup analyses were utilized.RESULTS:
The HPS group had a significantly higher education level, annual household income and larger prostate size. Compared with TURP, HPS resulted in comparable IPSS, QoL, Qmax and PVR improvements, but shorter hospitalization duration, serum hemoglobin loss and blood transfusion rate. Subgroup analyses showed that men in the HPS group were younger (age<76 years), had higher BMI (≥24kg/m(2)) and greater adjusted IPSS and QoL improvements than men in the TURP group.CONCLUSION:
HPS offered adequate effectiveness for symptomatic BPH versus TURP and was advantageous with regard to operative safety. Patients who are younger and have higher BMI may achieve better improvements with HPS than with TURP. Further long-term follow-up study is warranted.Palabras clave
