Title: Transurethral management of urethral obliteration using new KTP/532 laser vapori zation
Abstract: Objective To investigate the effect of new KTP/532 laser in transurethral management of urethral obliteration. Methods New KTP/532 laser was applied in 18 male patients with ureth ral obliterations by vaporizing the obliterated fibrotic tissue.Their mean age w as 35 years(range,19-61 years).The urethral obliteration was due to pelvic fract ure with posterior urethral breaking in 16 cases, and straddle injury of bulbour ethral in 2 cases.The disease course ranged from 10 months to 4 years.The oblite ration length was 1.6 to 2.5 cm with a mean of 1.9 cm.Postoperative catheterizat ion lasted 4 to 8 weeks.Uroflowmetry was performed after removal of the urethral catheter. Results The procedure was performed successf ully at one-stage in all 18 cases without complication, except for 1 case who d eveloped extravasation of small amount of urine.The duration of the procedure ra nged between 20 and 60 min, with a mean of 35 min.During the follow-up of 2-6 m onths,16 cases were treated successfully and voided fluently.The Qmax was more than 15 ml/s in all of them.The other 2 cases had Qmax less than 9 ml/s 2 weeks after removal of the catheter, and then got satisfactory results(Qmax15 ml/s) after regular urethral dilatation. Conclusions The exper ience with transurethral management of urethral obliteration using new KTP/532 l aser vaporization suggests that it is not only safe and effective but also has a dvantages of simple manipulation, fewer complications and rapid recovery.
