A congenital anomaly, also called a birth defect, means a baby is born with kidney or urinary tract structures that have developed differently. These anomalies occur during development in the womb. While some forms of CAKUT are part of a syndrome or are passed down in families, most occur randomly. 

Types of CAKUT include:

  • Double ureter (ureteral duplication): two ureters — rather than one ureter, which is normal — drain a single kidney
  • Horseshoe kidney (renal fusion): kidneys that fuse together, forming a horseshoe shape
  • Meckel-Gruber syndrome: causes enlarged kidneys with fluid-filled cysts
  • Posterior urethral valve: an opening in the urethra (tube that urine flows through) that prevents urine from leaving the body 
  • Prune belly syndrome (PBS or Eagle-Barrett syndrome): causes urinary tract malformations
  • Renal dysplasia: malformed structures within one or both kidneys 
  • Ureteropelvic junction (UPJ) obstruction: part of the kidney is blocked

Symptoms vary, depending on the anomaly, but may include:

In 2016, the state of Florida renewed our designation as a Comprehensive Chronic Kidney Failure Center (CCKFC). We are one of only three such centers in the state.

Pair Donor Exchange Program for kidney transplant. If your child needs a kidney transplant, we’re experts in transplant and follow-up care. Our Pair Donor Exchange Program can help shorten your child’s wait time for a kidney. This program increases the opportunity for children who are incompatible with a majority of donor kidneys to be transplanted. Because the child receives a kidney from a living donor, they will usually have a better outcome.
