Duplication Anomalies of the Urinary Tract
What is a duplication anomaly of the urinary tract?
Rarely, a child is born with extra, duplicative parts of the urinary tract. This could mean an additional kidney, bladder, penis, ureter (tube that connects the kidney and bladder), urethra (tube that connects the bladder with the outside of the body), or other part.
What causes a duplication anomaly?
While there is some research on the individual varieties of duplication anomalies, overall there is no known cause for the duplications that can occur.
How is it treated?
Sometimes, the "extra part" is nonfunctional and harmless but in many cases the duplicate part interferes with the normal flow of urine and/or semen. In these cases, surgery is necessary.
