Arrive with Comfortably Full Bladder
Drink 32 ounces (approximately 1 liter) of water about 1 hour before your appointment.
You should feel the urge to urinate when you arrive - similar to:
- "I need to go soon"
- Moderate urgency level
- Comfortably full, not painfully full
⚠️ Important: Do not empty your bladder right before the test unless instructed by your healthcare team.
