在这里, 我们分享我们的经验与 PVRP。首先, PVRP 能够更好地暴露前列腺胶囊的正确标定和降低胶囊穿孔的风险。第二, 应沿手术胶囊进行组织切除, 特别是在12点的凹槽上进行, 这有利于前列腺尿道周围的组织切除, 并提供满意的组织切除率。第三, 在前列腺尿道中先切除中叶, 以获得更宽的通道, 提高手术的可视化效果是至关重要的。如果有大的中间裂片与膀胱颈部介入, 我们强烈建议, 标记应绘制在...

虽然经尿道前列腺切除术仍被接受为金标准的良性前列腺增生 (BPH) 外科治疗, 激光手术已逐渐变得更加流行, 由于更好的病人耐受性, 少术中失血, 疗效满意, 术后恢复较短1,2,3。目前, 世界上最常用的用于 BPH 治疗的激光器是由锂钾草酸磷酸酯或锂三硼酸 (杠杆) 晶体 4, 5 生成的.传统上, 这些被归类为 sidefiring 激光器, 与其他类型的激光相比, 如钬激光和铥激光器。
选择性绿激光汽化的前列腺 (PVP) 手术可能大大降低经尿道炎综合征, 由于盐水灌溉6, 7, 并与其他类型的激光器相比, 下尿路综合征 (LUTS) 的可靠疗效PVP 通过一系列研究得到验证8,9,10。然而, 与侧向发射激光发射相关的 PVP 也有一些缺点, 包括能量损失近20% 和短寿命的激光光纤11,12,13。此外, PVP 还增加了由于完全组织汽化而导致前列腺癌漏诊的可能性。
采用端选择性绿激光 Vaporesection 的前列腺 (PVRP) 的引入成功地克服了上述 PVP 的大部分缺点。首先, 尖端是能够发射激光到组织几乎没有能量损失术。其次, 当纤维碎片在刀尖上采集时, 简单地去除受影响的零件, 就可以直接保持理想的输出功率。最后, 激光切除可使标本的采集用于术后病理检查。因此, 采用本协议治疗前列腺增生症可提高组织切除率, 节省手术时间, 提高术中的安全性。

photoselective vaporesection of the prostate via an end-firing lithium triborate crystal laser

良性前列腺增生 (BPH) 所致下尿路症状 (LUTS) 的发生是老年男性人群中发病率较高的常见问题。虽然它不是一种危及生命的疾病, 但 BPH 会引起严重影响生活质量的问题。在这里, 我们介绍了一种新的技术, 称为前列腺选择性绿激光 vaporesection (PVRP) 治疗前列腺增生症, 这可以看作是选择性绿激光汽化前列腺 (PVP) 的变化。与 PVP 技术相比, 激光能量损失少, 术中并发症少, 组织切除率更低, 具有较好的应用效果。

在我们的一项研究中, 共有35名接受 PVRP 的病人被纳入其中。平均患者年龄为 72.1, 7.1 岁 (范围53-85 年)。
围手术期数据列在表 1中。平均激光发射时间占平均手术时间的近50%。大多数患者的失血是 < 200 毫升。然而, 由于一些中等程度的出血病例, 平均偏差。近90% 的患者在术后6天内取出导管。
