What could happen if urine is allowed to flow back into the bladder from the urinary drainage bag?

1. Hemorrhage

2. Urethral blockage

3. Urinary Tract Infection (UTI)

4. Kidney stones

The correct answer is: Urinary Tract Infection (UTI)

When urine flows back into the bladder from a urinary drainage bag, it poses a significant risk of introducing bacteria into the bladder. This condition, known as retrograde flow, can lead to an increased likelihood of bacterial growth and colonization, which may result in a urinary tract infection (UTI). UTIs are caused by pathogens entering the urinary tract, and when urine is allowed to flow back, it creates a favorable environment for bacteria to multiply. This is particularly concerning in individuals with urinary catheters or drainage systems where sterilization is critical to preventing infections. While other health issues related to the urinary system may occur, such as urethral blockage or kidney stones, these conditions are generally not directly caused by the backflow of urine from a drainage bag. Hemorrhage is also unrelated to this specific issue and typically pertains to trauma or other medical conditions affecting blood vessels. Thus, the primary risk associated with the backflow of urine is the potential for developing a UTI.
