OBJECTIVES: To describe the renewed interest in Candida infections in general and urinary tract infections in particular, due to a recrudescence of immunodepressed patients and a better knowledge of their clinical and radiological manifestations. MATERIAL AND METHODS: The authors report 2 cases of Candida bezoars diagnosed by IVU, ultrasonography and CT scan in two insulin-dependent diabetics. RESULTS: The first case presented with right renal involvement, in the form of delayed renal secretion on IVU with the presence of a pelvic filling defect, dilatation of the upper tract cavities on ultrasonography with a dilated renal pelvis occupied by an echogenic formation with no posterior acoustic shadow. CT showed a slightly heterogeneous low-density lesion with no contrast enhancement. The second case presented with right pelvic and vesical involvement. The diagnosis of urinary candidiasis was confirmed, in the first case, by the presence of whitish lumps on catheterization, for which analysis and culture were in favour of candidiasis and, in the second case, by direct examination and urine culture. Treatment with amphotericin B led to improvement followed by disappearance of the signs in both cases. CONCLUSION: In addition to laboratory examinations, noninvasive imaging techniques, mainly ultrasonography and CT, but also percutaneous aspiration, constitute a decisive element in the diagnostic and therapeutic management of urinary candidiasis.
