Ureteral laser lithotripsy in bilharzial and non bilharzial patients using pulsed-dye laser follow-up for 18 months

ABSTRACT

The pulsed-dye laser was tried in fragmentation of ureters calculi in 60 patients. The maneuver has been achieved successfully in 56 cases. 33 of those patients gave positive history of B. infestation and anti B. Treatment. The small diameter and flexibility of the laser fibre enabled us to pass it through the miniscope [6.9 F.] which was suitable for children and patients with bilharzial ureteral affection, as dilatation in such cases will lead to crack in the tough wall of bilharzial ureter, with great possibility of stenotic complications later on. All stones seen endoscopically and treated with pulsed dye laser were fragmented including those of calcium oxalate monohydrate. Late follow up [1 1/2 years revealed negligible complications
