Bladder outflow obstruction due to benign prostatic enlargement affects up to a third of men over the age of 50. To date, the only reliable form of treatment is surgical, mainly by transurethral resection of the prostate (TURP). An alternative technique, endoscopic laser ablation of the prostate (ELAP) has recently been introduced to overcome some of the drawbacks of TURP. ELAP involves directing laser energy via a specially designed side-firing fibre at the enlarged portion of the prostate. The fibre, passed into the prostate through a cystoscope, carries the energy from the laser to the prostate causing heating of the prostate and subsequent shrinkage of the gland. The operation is performed under general or spinal anaesthetic and is quicker to perform than a TURP. Because the laser causes virtually no bleeding, patients can be treated as day cases or go home the day after surgery. A catheter is left in the bladder and is removed as an out-patient a few days later. The early results of ELAP are comparable to TURP, but complications and length of hospital stay are less.
良性前列腺增生导致的膀胱流出道梗阻影响着多达三分之一的50岁以上男性。迄今为止，唯一可靠的治疗方式是手术，主要是经尿道前列腺切除术（TURP）。最近引入了一种替代技术——前列腺内镜激光消融术（ELAP），以克服TURP的一些缺点。ELAP包括通过一根专门设计的侧向发射光纤将激光能量导向前列腺的增生部分。该光纤通过膀胱镜插入前列腺，将激光能量传递到前列腺，导致前列腺受热，随后腺体缩小。手术在全身麻醉或脊髓麻醉下进行，比TURP更快完成。由于激光几乎不引起出血，患者可作为日间手术病例接受治疗，或在术后第二天回家。一根导尿管留在膀胱内，几天后作为门诊病人取出。ELAP的早期结果与TURP相当，但并发症和住院时间较少。
