RESUMEN
Objective To explore the efficacy and safety of 980 nm diode laser therapy for treatment of benign prostatic hyperplasia (BPH). Methods Data of 170 patients with BPH treated with 980nm diode laser system were reviewed. The mean operative time, blood loss, surgical complications, the international prostate symptom score (IPSS), bladder residual urine volume and flow rate changes were collected and analyzed. Results One hundred and seventy cases were safe during the perioperative period. The average operation time was (74 ± 11) min, surgical removal of prostate tissue mass of (54±12) g, blood loss (72±11) ml. There was no TUR syndrome occurred. 170 patients were followed up 2 to 24 months. The IPSS decreased from preoperative 25.0±5.5 to 9.0±2.5. The maximum flow rate increased from preoperative (6.2±2.3)ml/s to post-operative (17.4±3.5) ml/s. The residual urine volume decreased from preoperative (210.0±25.6) ml to postoperative (25.2±4.6) ml. All the differences were statistically significant (P＜0.05). Conclusion Transurethral vaporization of 980 nm diode laser could be a safe and effective treatment modality for BPH.
