Abstract
Sapphire tips increase the energy density and cutting effect of a neodymium:YAG laser. Sapphire tipped neodymiumi:YAG laser fibers were used to perform urethrotomy in 24 men with benign urethral strictures. The cutting effect was inadequate in 10 patients.Of the 24 patients 16 (67%) had a recurrent stricture within 1 year. Sapphire tipped neodymiumi:YAG laser fibers offer no apparent advantage over cold knife urethrotomy for treatment of benign urethral strictures. (J. Urol., 142: 1221-1222, 1989)
