[Value of ultrasonics and computerized axial tomography in the staging of renal neoplasms].

Sonographic (US) and computed tomographic (CT) images obtained in 47 patients with renal cancer have been reviewed; attention was paid to detection of neoplastic spread to structures surrounding the tumor, presence of lymph node metastases and of thrombosis of renal vessels and to identification of distant metastases. The results of the revision process were then compared with surgical or autoptic findings. In a relatively high number of patients, a complete examination of the upper abdomen could not be performed by US, due to patient habitus or bowel gas; on the contrary, a diagnostic study could be obtained by CT in virtually all cases.

[Renal changes in acute leukemia in children at onset. Incidence and prognostic value].

Microscopic leukemia infiltration of kidneys is a common autoptic finding in children for ALL before starting specific treatment. However, a palpable renal enlargement is uncommon. The authors have performed an intravenous pyelogram (IVP) in 139 pediatric cases of acute leukemia, 117 of whom ALL, the remaining 22 ANLL.
