Overview of Pediatric Renal and Urinary Disorders
Definition and Epidemiology: Pediatric renal and urinary disorders refer to a wide range of conditions affecting the kidneys and urinary tract in children. They can result from congenital anomalies, acquired diseases, or infections. These disorders contribute significantly to childhood morbidity and may have long-term implications for renal function.
Classification: Pediatric renal and urinary disorders can be broadly classified into congenital anomalies, glomerular diseases, renal tubular disorders, urinary tract infections (UTIs), nephrotic syndrome, renal neoplasms, renal failure, and renal transplantation.
Congenital Anomalies of the Kidney and Urinary Tract
Vesicoureteral Reflux (VUR)
Definition: Retrograde flow of urine from the bladder into the ureters and potentially up to the kidneys.
Diagnosis: Voiding cystourethrogram (VCUG) is the gold standard for diagnosis.
Management: Treatment options include prophylactic antibiotics, surgical correction, or observation depending on the severity and presence of complications.
Hydronephrosis
Definition: Dilatation of the renal pelvis and calyces due to urinary tract obstruction.
Diagnosis: Ultrasonography is the initial imaging modality of choice.
Management: Treatment depends on the underlying cause, ranging from observation, medical therapy, to surgical intervention.
Polycystic Kidney Disease (PKD)
Definition: Genetic disorder characterized by the presence of multiple cysts in the kidneys.
Types: Autosomal Dominant PKD (ADPKD) and Autosomal Recessive PKD (ARPKD).
Diagnosis: Imaging studies such as ultrasound or computed tomography (CT) can confirm the diagnosis.
Management: Supportive care, blood pressure control, and management of complications.
