Posterior urethral valve
Posterior Urethral Valve
The Posterior Urethral Valve (Pronunciation: poh-STEER-ee-or yoo-REE-thrul VALV) is a medical condition that primarily affects male infants. It is a congenital disorder, meaning it is present at birth.
Etymology
The term "Posterior" is derived from Latin, meaning "back" or "behind". "Urethral" refers to the urethra, the tube that carries urine from the bladder out of the body. "Valve" is from the Latin "valva", meaning "a leaf of a door".
Definition
A Posterior Urethral Valve is an abnormality of the urethra where a thin membrane or a pair of thin leaflets are found in the posterior (back) part of the urethra. This can obstruct the flow of urine from the bladder, leading to various urinary tract problems.
Symptoms
Symptoms of a Posterior Urethral Valve can include difficulty urinating, urinary tract infections, and in severe cases, kidney damage.
Diagnosis
Diagnosis of a Posterior Urethral Valve is typically made through ultrasound imaging during pregnancy or after birth. Other diagnostic tests may include a voiding cystourethrogram (VCUG), which can show the presence of the valve in the urethra.
Treatment
Treatment for a Posterior Urethral Valve can involve surgery to remove the valve and relieve the obstruction. In some cases, long-term treatment may be needed to manage any resulting kidney damage or urinary problems.
