ABSTRACT

The pulsating colour laser generates a shock wave with a high energy power capable of shattering urinary calculi. Owing to their location and impaction, certain ureteral require intraureteral fragmentation, and ureteroscopy with a semi-rigid miniureteroscope permits the use of laser beams. We have treated 70 patients with ureteral lithiasis with this method and obtained complete fragmentation of the calculi in 61 patients, ascent of the calculus to caliceal cavities in 7, whilst no fragmentation was achieved in 2. No case required a surgical operation and no complications were observed. Laser therapy in the treatment of ureteral lithiasis.
