Neodymium:YAG laser treatment of bladder neck contracture following prostatectomy

A total of 21 patients with postprostatectomy bladder neck contracture underwent treatment with Nd:YAG laser irradiation. A new 800-microns hemispherical optical quarz fiber was used in contact technique to produce linear incisions in the scarred tissue. Within 11.2 months, median of follow-up, there was improvement in the obstructive voiding symptoms in all the patients. Two patients who had still mild contracture in the first follow-up cystoscopy were managed successfully with a second treatment. Endoscopic application of laser energy in the contact mode enables the immediate vaporization and disintegration of the fibrous area and secondary reepithelization of the bladder neck without scarring.
