The Division’s comprehensive diagnostic capabilities include the full complement of radiology services. Kidney biopsies are routinely performed in children of all ages for diagnostic purposes. Biopsies are performed with ultrasound guidance and conscious sedation in our Pediatric Sedation Unit. In most cases patients are able to go home the same day as the procedure.
Very young children with end stage renal disease who might be too small to be considered for transplantation are generally placed on peritoneal dialysis since it can be done at home at night while the child and family sleeps. Peritoneal dialysis involves placement of the catheter into the abdominal cavity, making access easier than for hemodialysis, which requires access through a vein. Newborns can also start peritoneal dialysis at birth.
For school-aged children, peritoneal dialysis helps to normalize their lives, enabling them to attend school full-time and participate in their usual activities while getting treatment for kidney failure. Hemodialysis, which is recommended for children who are older, is performed at the Hospital or in a dialysis center. Since hemodialysis can be a three-hour process, volunteers or Child Life Specialists are often available to interact with the children during this time.
Our capabilities include interventional radiology services for the evaluation of children who have hypertension as the result of a renovascular condition. We are the major referral center in the metropolitan area for our expertise in performing arteriographic studies to allow us to evaluate arteries in small children. We are also seeing increasing numbers of children with high blood pressure that may be related to being overweight. Our Division is currently participating in an NIH-approved protocol looking at children with obesity and hypertension, their vitamin D metabolism, and other aspects of their pathophysiology.
We offer 24-hour ambulatory blood pressure monitoring to evaluate children and adolescents with elevated blood pressure readings to distinguish those with “white coat” hypertension from those with an elevation of their blood pressure due to medical reasons. Our staff also participates in trials of blood pressure medications in children with high blood pressure and management of anemia in chronic kidney disease.
