Purpose of review: To summarize recent publications on the topic of laser in urology and explore new developments which may impact the future role of lasers in surgery.
Recent findings: Ho: Yttrium-aluminium garnet (YAG) laser with Moses technology allows less retropulsion during a lithotripsy, yet its efficacy needs to be tested in clinical trials. Data on the efficacy of this device for benign prostatic obstruction treatment is also pending. A new promising generation of laser systems - thulium-fiber (Tm-fiber) lasers - has been introduced. Tm-fiber has already been shown to be effective and well tolerated in endoscopic enucleation of the prostate and has demonstrated favorable outcome compared with Ho:YAG in preclinical lithotripsy studies. However, more studies are needed to better understand the use of this novel technology and elucidate its role within the armamentarium of available technologies.
Summary: Lasers remain an integral part of benign prostatic hyperplasia surgery and stone treatment and gain popularity in en-bloc resection of bladder cancer. Current efficacy of laser systems in prostate cancer ablation and their place in laparoscopy remain unclear, despite promising initial reports.
