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 (Qmax), 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 Qmax 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.
