Comparison of neodymium-doped yttrium aluminum garnet laser treatment with cold knife endoscopic incision of urethral strictures in male patients . OBJECTIVE To assess the effectiveness of visual laser ablation treatment with neodymium-doped yttrium aluminum garnet ( Nd : YAG ) laser in male patients with urethral strictures and to compare the effects with those obtained in patients treated with Sachse 's optical urethrotomy . MATERIALS AND METHODS Fifty patients aged 22 to 83 ( mean age 61.8 ) with primary ( n = 26 , 52 % ) and recurrent ( n = 24 , 48 % ) urethral strictures 0.3 to 2.4 cm long qualified for the study . The patients were randomized into two groups : 30 men treated using visual laser ablation of urethral strictures ( VLASU ) with Nd : YAGlaser and 20 men treated by correction of urethral strictures using Sachse 's optical urethrotomy . RESULTS At 12-month follow-up , seven ( 35 % ) patients who underwent optical urethrotomy and 21 ( 70 % ) in the VLASU group did not require repetition of the procedure . The choice of VLASU as a method of treatment significantly decreased the probability of therapeutic failure and recurrence of urethral strictures ( p = 0.02 ) . CONCLUSION VLASU can be used as a method of treatment of this disorder . It is an effective , modern , low-invasive , and repeatable technique and is technically simple and easy to master . It can be used in cases in which introduction of a 22 Char optical urethrotome into the stricture site is impossible , as well as for treatment of multiple strictures during one procedure .
