Background:
We report about our experiences with photoselective vaporization of the prostate (PVP) in patients with symptomatic benign prostatic hyperplasia (BPH) and total prostate volume larger than 80 cm(3).
Patients And Methods:
The study included 201 patients with BPH: 51 (25.4%) patients had a prostate volume larger than 80 cm(3) and 150 (74.6%) patients had a volume smaller than 80 cm(3) in the preoperative transrectal ultrasound.
Results:
The mean operation time for patients with large prostates was 79 min. Neither TUR syndrome nor severe bleeding was observed. In patients with large adenomas peak urinary flow increased by 135, 136, and 132% after 6, 12, and 24 months, respectively. The overall complication rate was comparable in both groups.
Conclusion:
PVP is characterized by excellent perioperative safety and significant improvement of voiding parameters. PVP is feasible in patients with large prostates.
