Rectal Urine Instillation: Significant Health Risks and Contraindications

Introducing urine into the rectum is not safe. Urine contains waste products, bacteria, and variable pH. Rectal mucosa is not designed for urine exposure. Risks include:

• Chemical irritation and mucosal damage
• Bacterial translocation → sepsis
• Electrolyte imbalance (absorption of urea, ammonia)
• Disruption of rectal microbiome
• Potential for fistula formation with repeated trauma

This practice has no medical indication and should be avoided.
