Living with Duplication of urethra

A very rare condition present at birth in which a person has an extra urethra, the tube that carries urine out of the body.

Understanding Duplication of urethra

Duplication of urethra is a very rare condition in which a person has an extra urethra instead of the usual single one.

The urethra connects the bladder to the outside of the body. There are three types: incomplete duplication, complete duplication, and duplication that comes from two bladders. It can occur along with other differences of the urinary tract, genitals, and the anus and rectum. It is present from the newborn and infant years.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Extra urethra
  • Epispadias (urethra opening on top of the penis)
  • Hypospadias (urethra opening on the underside)
  • Urine flowing backward toward the kidneys (reflux)
  • Differences of the anus and rectum

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists, kidney specialists and urinary and male reproductive system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
