[Application of laser technology in the treatment of ureteral lithiasis]. / Aplicación de la tecnología láser en el tratamiento de la utiasis ureteral.

OBJECTIVES: To evaluate the contribution of laser, mainly holmium laser, to the endourological treatment of ureteral lithiasis. METHODS: We analyze our experience in 154 endourological treatments of ureteral lithiasis with holmium laser performed in our Unit from June 2005 to December 2007. RESULTS: Stone fragmentation was achieved in 100% of the cases. The use of long jaw forceps associated with the holmium laser enabled us to reach a stone free rate of 91%. CONCLUSIONS: The treatment of ureteral lithiasis has benefit from the development of endoscopic procedures, being the holmium laser the energy source of choice nowadays. The fragmentation rate was 100%. Complications were rare and never important.
