[The use of laser technology for the treatment of ureterointestinal stenosis]

Ureteral-intestinal anastomosis represent on important problem in patients undergoing radical cystectomy with urinary diversion using intestinal segments, either small or large intestine. With the incorporation of laser technology in urology, new therapeutic possibilities have been opened for the section of these ureteral intestinal stenosis. Various types of laser had been employed to perform the incision, Nd:YAG, KTP:YAG, Ho:YAG, Er:YAG, and Th:YAG. The experience is limited in terms of use and results don't give clear therapeutic orientation. The section of ureteral-intestinal stenosis with laser has advantages and disadvantages, but the application of this energy source with various techniques of endoscopic section, such as the Lovaco's technique of endoluminal invagination and endoureterotomy gives satisfactory results in the short-midterm.
