Long-Term Outcomes of 80-Watt KTP and 120-Watt HPS GreenLight Photoselective Vaporization of the Prostate

Abstract

Objective: Photoselective vaporization of the prostate (PVP) is becoming a surgical treatment alternative of transurethral resection of the prostate for male lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO). We evaluated the outcome and postoperative complications of PVP performed by 80-W KTP and 120-W HPS GreenLight lasers (AMS®) over a 4-year period. Materials and Methods: This is a prospective monocentric study that included all patients who underwent PVP. They had routine follow-up at 1 month, 3 months, 6 months and every year until the fourth postoperative year. Listed data were maximum urinary flow rate (Q_max), International Prostate Symptom Score (IPSS), post-void residual (PVR) volume, prostate-specific antigen (PSA) and prostate volume. We collected the postoperative complications. Results: From September 2005 to May 2008, 77 patients out of a 409 patients cohort underwent surgery and were followed during 4 years. At 4 years mean Q_max increase was 82.5%; mean IPSS, PVR volume, PSA and prostate volume decreases were 79.1, 69.8, 43.8 and 22.9%, respectively. The main side effects observed were storage LUTS. A urinary catheter was replaced after a first withdrawal failure in 10 patients (15.6%) after surgery. Conclusions: PVP showed a sustainable efficacy and an appealing tolerance profile during a 4-year period in patients with LUTS secondary to BPO.

Prostatic Urethral Lift: A New Minimally Invasive Treatment for Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia

“…In the current study, a 3.9-point increase was found at the end of the 3rd month and a 4.2-point increase at the end of the 12th month. Functional improvements following PUL were less than those previously reported for TURP and PVP (10-13 ml/s) during 12-month follow-ups [18,19,20,21]. In parallel with Qmax values, there was a significant increase in Qavg at the end of the 3rd and 12th months.…”

Measurement of Procedure-Specific Irrigation-Fluid Absorption in Transurethral Therapy of Lower Urinary Tract Syndrome, Using Ethanolic Saline and Breath Alcometry

“…Barber et al [9], using an 80 W laser, did not detect any absorption, while Hermanns et al [8],using a 120 W laser, found that 44% of 50 patients investigated showed absorption with a median of 725 ml. Long-term results of such treatments with green-light lasers of 80 W [25], 120 W [26] and 180 W [27] have been reported, but because of differing study designs, they are not comparable.…”

Laser Therapy for Bladder Outlet Obstruction: A Prospective Analysis of All Patients Receiving Treatment with the GreenLight XPS 180-Watt Laser System after Introduction at a Single Center

“…The results show a high success rate, as only 4 of 67 patients that were already fitted with a long-term catheter were discharged with a long-term catheter in place [18]. However, secondary TURP was required in 4.2% of patients.…”
