Benign prostatic hyperplasia (BPH) is a disease of the prostate commonly seen in elderly males known to cause lower urinary tract symptoms (LUTS) that may require surgery as a part of treatment. Transurethral resection of the prostate (TURP) is considered the gold standard of surgical treatment, but it is not without complications. Laser photoselective vaporisation of the prostate (PVP), introduced in 1998 as an 80 W Nd:YAG laser which passed through a KTP (potassium-titanylphosphate) crystal, emerged as a safe alternative to TURP in selected cases. A recent upgrade to the Greenlight XPS 180 W powered with an LBO (lithium triborate) crystal has been available for use since 2012. Data on the use of this new upgrade is still being collected and analysed, especially in patients with large prostates or high risk cases. We analysed cases done at Jaslok Hospital over a 2-year period. Methods: A total of 34 patients who underwent Laser PVP using XPS 180W for LUTS due to BPH at Jaslok Hospital were part of this study. We analysed the pre- and postoperative variables and the intraoperative parameters of all patients. Results: The XPS 180W was found to be safe and efficacious. Eighteen patients were high-risk cases, classified as ASA (American Society of Anesthesiologists) Classes 3 and 4. Average postoperative catheter duration was 40.18 hours. In prostates of size &lt;80 mL, an average of 229 kJ of energy was used. In large prostates (&gt;80 mL), an average of 390 kJ of energy was used. No major complications were seen in any of the high-risk patients, classified as Clavien Dindo Class 3 and 4. The postoperative drop in IPSS (International Prostate Symptom Score) was 8.7. Conclusion: We found that Green Light Laser XPS 180W may be used for large (&gt;80 g) prostates, hitherto an indication for open surgery, and that it may be used in high-risk patients, who were otherwise unfit for TURP. It is safe and efficacious. Further, multicenter trials are required to confirm the findings.
