Introduction: Transurethral resection of the prostate (TURP) is still considered the gold standard surgical treatment for symptomatic benign prostatic hyperplasia (BPH). However, photoselective vaporization of the prostate (PVP) has gained widespread global acceptance in national guidelines as a safe and effective alternative option. Nevertheless, further evidence is required to assess the durability of Greenlight PVP. Herein, we report our five years of PVP experience with the Greenlight 180W XPS laser system. Methods: A retrospective analysis was conducted on a prospectively gathered database of 370 consecutively included patients who underwent PVP using Greenlight XPS-180 W laser system (Boston Scientific, Boston, MA, U.S.) performed by a single experienced laser surgeon between 2011 and 2016. Preoperative characteristics, intervention parameters, postoperative functional, uroflowmetry outcomes, and complications were collected. Outcomes are reported over a period of five years. Results: Mean age was 68 years, with a mean prostate volume of 78.8 cc (95% confidence interval [CI] 70.9-78.7]). The mean followup was 59.4 months (55.4-63.5). Mean energy, operative time, and energy/cc were 270.2 kJ (255.2-285.2), 62.7 minutes (59.6-65.7), and 3.7 kJ/cc (3.6-3.9), respectively. Compared to preoperative values, International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), and post-void residual (PVR) parameters were significantly improved and sustained over the five postoperative years. Of note, only 66 patients (out of 370) had a complete five-year followup. Prostate-specific antigen (PSA) reached nadir at one year, with a drop of 67% from the mean preoperative value of 6.2 ng/mL. Mean IPSS nadir was reached at three years, with a drop of 80.4% (-21.1 points). Similarly, mean quality of life (QoL) score dropped by 82.8% after three years (preoperative mean of 4.7). With respect to mean Qmax, there was an increase by 72.7% (+14.7 mL/s) at one year, reaching the value of 19.9 mL/s. Moreover, mean PVR was 32.8 mL at four years compared to 345 mL preoperatively. At five years followup, PSA, IPSS, QoL, and PVR dropped by 59.7% (3.7 ng/mL), 75.2% (19.7 points), 78.72% (3.7 points), and 84.4% (291.3 mL), respectively. Qmax increased by 12.9 mL/s. Clavien complication rates were low, with bladder neck stenosis observed in seven (1.6%) men. During the five-year followup, only four patients (1%) required BPH surgical re-intervention. Conclusions: This is the first long-term reporting of Greenlight XPS-180W laser system. In experienced hands, the observed outcomes appear to demonstrate that Greenlight XPS-180 W laser system is safe, efficacious, and durable for the treatment of bladder outlet obstruction (BOO) secondary to BPH.

Introduction: We sought to determine the impact of salvage radiotherapy (SRT) on oncological and functional outcomes of patients with prostate cancer after biochemical recurrence (BCR) following robot-assisted radical prostatectomy (RARP). Methods: Data of 70 patients with prostate cancer treated with SRT after developing BCR were retrospectively analyzed from a prospectively collected RARP database of 740 men. Oncological (prostate- specific antigen [PSA]) and functional (pads/day, International Prostate Symptom Score [IPSS], and Sexual Health Inventory for Men [SHIM]) outcomes were reported at six, 12, and 24 months after RT and adjusted for pre-SRT status. Results: Men who underwent SRT had a mean age, PSA, and time from radical prostatectomy (RP) to RT of 61.8 years (60.1-63.6), 0.5 ng/ml (0.2-0.8), and 458 days (307-747), respectively. Freedom from biochemical failure (FFBF) post-SRT, defined as a PSA nadir <0.2 ng/mL, was observed in 89%, 93%, and 81%, at six, 12, and 24 months, respectively. Undetectable PSA was observed in 14%, 35%, and 40% at the same time points, respectively. There was no significant difference in urinary continence post-SRT (p=0.56). Rate of strict continence (0 pads/day) was 71% at 24 months compared to 78% pre-SRT. Mean IPSS at six, 12, and 24 months was 3.4, 3.6, and 3.6, respectively compared to pre-RT score of 3.3 (p=0.61). The mean SHIM score pre-SRT was comparable at all time points following treatment (p=0.86). Conclusions: In this unique Canadian experience, it appears that early SRT is highly effective for the treatment of BCR following RARP with little impact on urinary continence and potency outcomes.
