Purple Urine Bag Syndrome (PUBS) is a rare medical condition that is characterized by the presence of purple-colored urine in individuals who have a urinary catheter and are suffering from a urinary tract infection. The condition is often associated with elderly patients, particularly those with long-term catheterization.

Causes

The primary cause of Purple Urine Bag Syndrome is a urinary tract infection caused by bacteria that produce indigo (blue) and indirubin (red) pigments. These pigments mix to create a purple color. The bacteria involved include Proteus mirabilis, Providencia stuartii, Klebsiella pneumoniae, and Escherichia coli.

Symptoms

The most obvious symptom of Purple Urine Bag Syndrome is the presence of purple urine. However, other symptoms may include fever, confusion, and abdominal pain. It is important to note that many patients with PUBS do not exhibit any symptoms other than the purple urine.

Diagnosis

Diagnosis of Purple Urine Bag Syndrome is typically made based on the presence of purple urine in a patient with a urinary catheter. A urine culture may also be performed to identify the bacteria causing the infection.

Treatment

Treatment for Purple Urine Bag Syndrome typically involves antibiotics to treat the underlying urinary tract infection. In addition, the urinary catheter should be changed.

Prognosis

The prognosis for Purple Urine Bag Syndrome is generally good, as the condition itself is not harmful. However, the underlying conditions that often accompany PUBS, such as urinary tract infections and long-term catheterization, can lead to complications if not properly managed.
