Abstract:
We present our experience in the treatment of ureteral lithiasis with pulsed dye lasertripsy (Pulsolith)**. Evaluation of the results achieved in 67 cases of lithiasis that had been treated from January, 1990 to March, 1991 revealed a success rate of 93%. The remaining cases required the use of other complementary energy to achieve stone fragmentation. The approach, the endoscopic technique using the Olympus ureteroscopes (7.2F-9F) and complementary maneuvers are described. The complications were minimal. We consider this to be the procedure of choice for calculi in the pelvic ureter. Furthermore, we discuss the cost/benefit of this therapeutic option within the context of a lithotripsy unit with a high endoscopic dedication and the possibility of using fine caliber ureteroscopes (Olympus) as well as other options for stone fragmentation (shock wave, ultrasound and electrohydraulic energy).
