Abstract:
Benign prostatic obstruction (BPO) is the most common cause of lower urinary tract symptoms among men. GreenLight photoselective vaporization of the prostate (GL‐PVP) using a 180‐W Xcelerated performance system (XPS) laser is a well‐established method for treating BPO‐induced voiding symptoms. However, its therapeutic effects on storage symptoms remain unclear. This study aimed to analyze the storage outcomes in patients who underwent 180‐W XPS GL‐PVP for BPO and to identify outcome predictors. Materials and Methods Patients who underwent 180‐W XPS GL‐PVP for BPO between May 2018 and May 2021 were retrospectively reviewed. Data on clinical characteristics, prostate volume, preoperative and postoperative International Prostate Symptom Scores (IPSS), and preoperative urodynamic parameters were collected. A favorable storage outcome was defined as ≥50% reduction in the IPSS storage subscore. Results Ninety‐nine male patients were included, with a mean age of 69.4 ± 9.6 years and a baseline prostatic volume of 75.9 ± 33.1 mL. The IPSS total, storage, and voiding subscores significantly decreased after GL‐PVP (all p 〈 0.001). Seventy‐two patients achieved favorable storage outcome at 6 months. Multivariate analysis revealed that detrusor underactivity was predictive of unfavorable storage outcomes ( p = 0.022), while IPSS voiding‐to‐storage subscore ratio 〉 1.25 and the presence of detrusor overactivity were predictive of favorable storage outcomes ( p = 0.008 and 0.033, respectively). Conclusion 180‐W XPS GL‐PVP provided excellent outcomes in both voiding and storage lower urinary tract symptoms concomitant with BPO. Preoperative IPSS and multichannel urodynamic parameters including detrusor overactivity and underactivity are valuable predictors of postoperative storage outcomes.
