From the Guidelines
For an US Abdominal with Kidney view, patients should be well-hydrated, except for a fasting period of 8-12 hours before the examination, to ensure clear visualization of the kidneys and abdominal organs. The preparation for the procedure involves wearing loose, comfortable clothing that allows easy access to the abdomen. Medications can typically be taken with small sips of water.
Key Preparation Steps:
- Fasting for 8-12 hours before the examination, though clear liquids may be permitted
- Wearing loose, comfortable clothing that allows easy access to the abdomen
- Taking medications with small sips of water
- Adequate hydration, except during the fasting period, to improve image quality The examination itself is painless and non-invasive, lasting approximately 30-45 minutes. During the procedure, patients will lie on an examination table while a technician applies gel to the abdomen and moves a transducer over the skin to capture images. For optimal kidney visualization, patients may be asked to hold their breath briefly at certain points. No sedation is required, and patients can resume normal activities, including eating and drinking, immediately after the procedure.
Follow-up Procedures:
- Patients with congenital nephrogenic diabetes insipidus should have follow-up tests and measurements, including clinical, blood, urine, and imaging tests, as recommended in the international expert consensus statement 1
- Kidney ultrasound should be performed at least once every 2 years to detect hydronephrosis, bladder wall hypertrophy, and post-micturition urine residue 1
- Patients with primary hyperoxaluria should have kidney ultrasound at least yearly to assess the presence of stones and nephrocalcinosis 1
From the Research
Preparation Procedures
- The patient should be instructed to fast for a certain period before the ultrasound examination, typically 6-8 hours, to ensure clear visualization of the abdominal organs 2.
- The patient should also be advised to drink plenty of water to fill the bladder, which helps to visualize the kidneys and urinary tract.
- Removal of clothing and jewelry from the abdominal area is necessary to ensure proper contact with the ultrasound probe.
Follow-up Procedures
- After the ultrasound examination, the patient may be required to undergo additional tests, such as blood work or imaging studies, to confirm the diagnosis or monitor the condition 3.
- The patient should be instructed to follow up with their healthcare provider to discuss the results of the ultrasound examination and any further treatment or management plans.
- In cases where kidney stones or other abnormalities are detected, the patient may be referred to a specialist, such as a urologist, for further evaluation and treatment.
Special Considerations
- Patients with a history of kidney disease or urinary tract infections should be closely monitored during and after the ultrasound examination to prevent any potential complications 3.
- The use of ultrasound contrast agents may be necessary in certain cases to improve diagnostic accuracy, especially in patients with complex abdominal pathology 2.
