Evidence of the efficacy and safety of the thulium laser in the treatment of men with benign prostatic obstruction.

In 2005, the high power thulium laser was introduced for the surgical treatment of benign prostatic obstruction. It has several properties that confer theoretical advantages over other lasers used for the same indication, such as technical versatility and a relatively small zone of thermal damage. Studies using the 70-150 W thulium laser systems demonstrate good efficacy of these procedures with low morbidity and few complications even in higher risk patients. Different techniques have been employed to treat the prostate with this technology, including enucleation, vapoenucleation, vaporization and resection. Comparative studies have been published comparing thulium laser prostatectomy to monopolar transurethral resection of prostate (TURP), bipolar TURP and holmium laser enucleation of prostate (HoLEP). In this review we discuss the current literature on the safety and efficacy of various thulium techniques for the treatment of benign prostatic hyperplasia and examine comparative studies.
