Posterior Urethral Valves (PUV) are abnormal flaps of tissue in the urethra (the tube that carries urine from the bladder out of the body). These valves can block the flow of urine, leading to a range of health issues. Understanding PUV is crucial for early diagnosis and treatment, especially since it can significantly affect urinary function and kidney health.
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.
Causes of Posterior Urethral Valves

- Embryonic Development: Abnormal development of the urethra during fetal growth.
- Hormonal Imbalances: Disruptions in hormonal levels affecting urethra formation.
- Maternal Health Issues: Conditions in the mother during pregnancy, such as diabetes or exposure to toxins.
