Abstract
AIM: An attractive alternative for the management of benign prostate hyperplasia (BPH) is the use of 80 W potassium titanyl phosphate (KTP). We evaluated the efficacy and safety of this procedure in patients with bladder outlet obstruction (BOO). METHODS: A total of 171 patients with obstructive BPH underwent the 80 W potassium-titanyl-phosphate laser procedures. Preoperatively the international prostate symptom score (IPSS), the maximal urinary flow rate (Qmax), prostate volume and the post-void residual urine volume (PVR) were determined. Perioperative complications and postoperative blood loss, hospitalization, catheterization time, Qmax and PVR were also assessed. RESULTS: From the 171 patients, who underwent KTP laser procedure, 143 have been evaluated. The mean preoperative prostate volume was 43.9+/-17.1 (15-76). Eighty-nine patients (62.2%) were on chronic oral anticoagulant therapy (Coumarin or Aspirin 100). The mean applied energy was 170+/-65 kJ (100-275). There was no significant blood loss or fluid absorption during the KTP procedure. The mean Qmax values preoperatively and postoperatively were 3.4+/-4.3 and 16.3+/-7.3, respectively. PVR decreased from 74+/-47.7 mL preoperatively, to 16.6+/-21.5 mL postoperatively. Catheteriza-tion time was 1.4+/-0.8 days (0-5). CONCLUSION: KTP laser for the prostate represents a safe and effective treatment for patients with BPH. The procedure has a low rate of postoperative complications. It can be used for high risk patients especially for them who are receiving oral anticoagulation therapy.
