Study Notes
Diuresis Renography Purpose
- Evaluates urinary tract obstruction by assessing tracer washout.
Procedure
- Furosemide is given intravenously to increase urine output.
- Imaging continues for about 20 minutes.
Patient Preparation
- Patients should be well-hydrated.
- Bladder should be empty.
- Patients should not be anuric or dehydrated.
- Patients who can't void voluntarily need catheterization.
Drug Interactions
- Increased bladder pressure may reduce furosemide's effect.
Contraindications
- Furosemide is not suitable for anuric or dehydrated patients.
Post-Surgical Precautions
- Use furosemide with extreme caution in patients after urologic surgery.
Data Acquisition
- Same as renal function study.
Furosemide Dosage
- Adults: 20-40 mg.
- Pediatric patients: 0.5-1 mg/kg.
Imaging Procedure
- Furosemide is injected slowly (1-2 minutes).
- Imaging continues for 20 minutes.
