根治性前列腺切除术被认为是前列腺癌唯一可行的治疗方法,但这项手术常伴有相当高的并发症,并且可导致性功能丧失。因此,医者很希望能有一些新的方法。对T_1和T_2期的前列腺癌可经TUR切除大部分的肿瘤组织,但一小部分的癌组织残留在前列腺被膜上。掺钕钇铝石榴石(Nd-YAG)激光破坏组织深度可达4-6 mm。当TURP和激光治疗一起使用时,可彻底消灭靠近前列腺被膜的癌组织,这对于根治性前列腺切除手术来说,也是一个可取代的方法。 Nd-YAG激光光束经一根可弯曲的石英纤维导光索传导,导光索便于从膀胱镜插入使用。治疗方法 Radical prostatectomy is considered the only viable treatment for prostate cancer, but this procedure is often accompanied by considerable complications and can lead to loss of sexual function. Therefore, doctors hope that there are some new ways. For T_1 and T_2 prostate cancer, most of the tumor tissue can be removed by TUR, but a small part of the cancer remains on the prostate capsule. Neodymium-doped yttrium aluminum garnet (Nd-YAG) laser tissue damage up to 4-6 mm depth. When TURP is used with laser treatment, cancerous tissue near the prostate gland can be completely eliminated, which is a viable alternative to radical prostatectomy. The Nd-YAG laser beam is guided through a flexible quartz fiber optic cable, which is easily inserted from the cystoscope. treatment method
