摘要
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.
