ABSTRACT
PURPOSE:
To determine the usefulness of transrectal ultrasound (TRUS) and to compare TRUS with intravenousurography (IVU) in the evaluation of distal ureteral calculi. MATERIALS ANDMETHODS:
TRUS and IVU were perfomed in 24 patients with distal ureteral calculi. Using TRUS, we evaluated the presence and size of calculus, type of ureteral jet at the affected site and diameter of ureter proximal to calculus, and using IVU evaluated the presence and size of calculus, degree of ureteral obstruction, and degree of hydroureter. TRUS and IVU findings, were compared.RESULTS:
In each patient, TRUS detected calculus of the distal ureter ; in only 18cases (75%),were the calculi demonstrated with IVU. In 18 cases where calculi were detected by both modalities, average calculus size was 4.5 X 3.0mm (longest and shortest dimensions) by IVU, and 6.1 X 3.7 mm by TRUS. Betwee TRUS and IVU(p0.05).CONCLUSION:
TRUS appears to be a useful adjunctive method for the evaluation of distal ureteral calculus.
