Posterior Urethral Valves

Pathophysiology

• Structure: The urethra is the passage through which urine exits the bladder. In PUV, abnormal tissue forms valves in the urethra, obstructing urine flow.
• Blood Supply: The blood supply to the urethra comes from branches of the internal pudendal artery, which provides oxygen-rich blood to the tissues.
• Nerve Supply: The nerves supplying the urethra are part of the pelvic plexus, which helps control urinary function. PUV can disrupt these signals, affecting bladder and kidney function.

Types of Posterior Urethral Valves

• Type 1: Membranous valves—thin membranes that obstruct the urethra.
• Type 2: Muscle tissue valves—thicker muscular tissue causing blockage.
• Type 3: Mixed valves—combination of membranous and muscular characteristics.
