Abstract
PURPOSE
This study was conducted to investigate the indicators of recovery in storage symptoms after GreenLight High Performance System photoselective vaporization of the prostate (HPS-PVP) in men with benign prostate hyperplasia.
METHODS
A total of 155 men with a baseline subtotal storage symptom score of international prostate symptom score (sIPSS) greater than or equal to six, who underwent HPS-PVP and were followed up on for as much as 3 years, were included in this retrospective study. Surgical outcomes were evaluated at 1, 3, 6, 12, 24, and 36 months after surgery. Improvement of storage symptoms was defined as a reduction greater than or equal to 30% of sIPSS after surgery compared to the baseline.
RESULTS
The mean age was 67.5 ± 7.8 years and the preoperative median prostate-specific antigen, mean total prostate volume, and sIPSS were 1.95 (0.97-5.27) ng/mL, 52.1 ± 32.5 mL, and 9.6 ± 2.6, respectively. The mean improvement rate of sIPSS after 3 years was 34.4%. Age was only associated with an improvement of sIPSS in the multivariate analysis (odds ratio = 0.889, p = 0.008). The mean improvement rates of sIPSS according to age group (<65 vs ≥65) were 44.7% and 26.0%, respectively.
CONCLUSIONS
Age can serve as an independent predictor of storage symptom improvement for as much as 3 years. Therefore, we suggest that older patients who are being considered candidates for surgical treatment should be further evaluated.
