Pre-B acute lymphoblastic leukemia with t(1;19) in an adult initially presenting as hematuria and bilateral renal enlargement: a case report and literature review.

Although pre-B acute lymphoblastic leukemia (ALL) is the most common type of renal leukemic infiltration; the renal infiltration with leukemia cells as the initial manifestation of leukemia is very rare. Translocation (1;19)(q23;p13) is one of the most common chromosomal abnormalities in patients with ALL and is observed in 5 - 6% of children with pre-B ALL. However, the incidence of t(1;19) in adults is lower, not exceeding 3%, and the prognosis of adult patients is usually poor.

A new method of kidney biopsy using low dose CT-guidance with coaxial trocar and bard biopsy gun.

Background: To explore a new method of kidney biopsy with coaxial trocar and bard biopsy gun under low dose computed tomography (CT)-guidance and evaluate its accuracy, safety, and efficacy.

Methods: Sixty patients underwent renal biopsy under CT-guidance. They were randomly divided into two groups: group I, low dose CT-guided (120 kV and 25 or 50 mAs) and group II, standard dose CT-guided (120 kV and 250 mAs).
