It is possible to assess the growth and size of the fetal kidney according to gestational age but this does not apply to the renal pelvis. A renal pelvic dimension of > 5 mm at any gestational age is unusual and dilatation beyond this level should prompt a detailed post-natal urological investigation.
The increased incidence of cerebral toxoplasmosis in AIDS has led to a resurgence in the use of sulphadiazine. One complication of this is acute renal failure secondary to sulphadiazine-induced crystalluria. Three cases are described which demonstrate a spectrum of ultrasound findings ranging from echogenic foci in the renal parenchyma to echogenic material in both dilated and non-dilated collecting systems. In patients with AIDS having sulphadiazine treatment, these ultrasonic findings suggest that sulphadiazine is the cause of the renal failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
