Abstract
Objective To explore the efficacy and safety of 1 470 nm diode laser vaporization in the treatment of benign prostatic hyperplasia (BPH). Methods Eighty-seven BPH patients were treated by 1 470 nm diode laser vaporization and followed up for 6 months. The patients were aged 55–82 years, with a mean prostate volume of (52.4±8.2) ml. The mean operation time, intra-operative blood loss, postoperative complications, international prostate symptom score (IPSS), quality of life (QOL) score, maximum urine flow rate (Qmax) , and post void residual (PVR) before and after surgery were analyzed and compared. Results Operations were successful in all of the 87 cases, with an average operation time of (66±10) min, little blood loss and no blood transfusion. The transurethral catheter indwelling time was 20–70 h (33±5 h). The patients were followed up for 6 months, which revealed a significant reduction in IPSS and QOL (P<0.01) and improvement in Qmax and PVR (P<0.01) as compared with preoperative parameters. Conclusion Transurethral 1 470 nm diode laser vaporization is a safe and effective treatment for BPH. Key words: Benign prostatic hyperplasia; Diode laser; Vaporization
