Abstract
Objective: Extracorporeal shock wave lithotripsy for treatment of
ureteric calculi is difficult due to reduced visibility of the stone. Intravenous contrast medium (IV-CM)administration may overcome this problem by indirect depicting the localization of the stone . The aim of the study was to compare the clinical outcome after ESWL in two representative groups of patients with either radiolucent or radio- opaque ureteric calculi
Patients and methods: between march 2000 to December 2001, two groups of the patients, 50 patients with radiolucent ureteric calculi and 50 patients with radiopaque ureteric calculi as a control groups were treated with shock wave lithotripsy in Sohag university hospital. The two groups were assessed regarding age, sex, treatment modality, complications, and stone free treat 6 months after treatment
Results: There is no significant between the two groups as regard to age and sex, also rather is no significant difference in the number and energy shock wave applied in both groups. Stone free rate were well
and within the percentage described by other investigator. The were no adverse reaction to contrast medium
Conclusion: ESWL with help of IV –CM administration should be the first-line therapy for treatment of radiolucent ureteric stone, being non invasive. Although awareness of possible adverse reaction to CM is mandatory; the risk remains small.
