Abstract

BACKGROUND

Transurethral visual laser ablation of the prostate (VLAP) has been established as an alternative method for the treatment of benign prostatic hyperplasia (BPH). However, most VLAP procedures utilize only a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. Since a potassium-titenyl-phosphate (KTP) laser offers limited tissue penetration, KTP can be safely utilized to excise part of the obstructing prostatic tissue. This study assessed the interaction between KTP vaporization and YAG coagulative ablation to determine the safety and efficacy of VLAP utilizing a combined KTP/YAG treatment.

METHODS

Forty patients with bladder outlet obstruction secondary to BPH were treated with VLAP using a KTP/YAG laser. The laser light was delivered by an angle delivery device.

RESULTS

Most cases demonstrated a significant improvement in routine subjective and objective parameters (AUA symptom score, peak flow rate, average flow rate, and amount of residual urine). No significant complications relating to this procedure were reported, however, 4 patients experienced postoperative acute urinary retention.

CONCLUSION

KTP/YAG laser ablation of the prostate is safe and effective for the treatment of BPH.

摘要

背景

经尿道可视化激光前列腺切除术（VLAP）已被确立为治疗良性前列腺增生（BPH）的一种替代方法。然而，大多数VLAP手术仅使用钕：钇铝石榴石（Nd:YAG）激光。由于磷酸钛氧钾（KTP）激光的组织穿透性有限，KTP可安全地用于切除部分阻塞性前列腺组织。本研究评估了KTP汽化与YAG凝固性消融之间的相互作用，以确定联合使用KTP/YAG治疗的VLAP的安全性和有效性。
