posterior urethral valve , PUV (Abkürzung)

There are three specific endoscopic treatments of posterior urethral valves:

Causes include urolithiasis, posterior urethral valves and ureteral herniation.

Anatomical: Posterior urethral valves; urethral or meatal stenosis.

A posterior urethral valve is an obstructing membrane in the posterior male urethra as a result of abnormal in utero development.

Posterior urethral valve (PUV) disorder is an obstructive developmental anomaly in the urethra and genitourinary system of male newborns.

Features that suggest posterior urethral valves are bilateral hydronephrosis, a thickened bladder wall with thickened smooth muscle trabeculations, and bladder diverticula.

The congenital urothelial remnants of type III posterior urethral valves have been eponymously referred to as Cobb's collar or Moorman's ring.

A voiding cystourethrogram (VCUG) is also typically obtained to exclude the possibility of vesicoureteral reflux or anatomical abnormalities such as posterior urethral valves.

Following surgery, the follow-up in patients with posterior urethral valve syndrome is long term, and often requires a multidisciplinary effort between urologists, pulmonologists, neonatologists, radiologists and the family of the patient.

The verumontanum is an important anatomic landmark for pathology in a congenital anomaly known as posterior urethral valves, in which there is a developmental obstruction of the urethra in newborn male infants.

Alternately, severe bilateral prenatal hydronephrosis (such as occurs with posterior urethral valves) will likely carry a poor long-term prognosis, because obstruction while the kidneys are developing causes permanent kidney damage even if the obstruction is relieved postnatally.
