Endoscopic Nd:YAG Laser Coagulation of Intramural Endometriosis of the Bladder.

Treatment of intramural endometriosis of the bladder using the Nd:YAG laser is described. An operative cystoscope fitted with a 600 µ fibre is introduced into the bladder. At a power setting of 50 W, superficial coagulation of the visible lesion is performed. The coagulation technique corresponds to that used for the treatment of superficial bladder carcinomas. Three patients were managed in this way. In all patients dysuria and hematuria either significantly decreased or disappeared altogether. No intraoperative complications were observed. This new technique appears to be superior to surgical excision techniques, especially in cases where the lesion is situated on the roof of the bladder. Further studies need to be conducted to compare results obtained from this technique with those of the CO2 laser or excision technique.
