Upper and lower abdominal ultrasonography (Upper and Lower Abdomen USG) is one of the most commonly used imaging methods for evaluating the organs and soft tissues located in the abdominal area.
This examination, which does not involve radiation, is non-invasive, and provides real-time imaging;
- Abdominal pain,
- Bloating,
- Palpable mass,
- Digestive system complaints,
- Evaluation of abdominal diseases
provides important information in such cases.
With Upper and Lower Abdomen USG, the intra-abdominal organs can be examined in detail, and findings that will guide further investigation or treatment planning can be obtained if necessary.
Since the abdominal region contains many organs together, it may not always be possible to determine the source of complaints by physical examination alone. Ultrasonography significantly contributes to the diagnostic process by helping to evaluate the structural characteristics of the organs and their relationship with surrounding tissues.
What is Upper and Lower Abdomen USG?
Upper and Lower Abdomen USG is an ultrasonographic examination that uses high-frequency sound waves to provide real-time imaging of the organs inside the abdomen.
This examination:
- Does not involve radiation,
- Is non-invasive,
- Does not require any intervention during the procedure,
- Allows real-time evaluation of intra-abdominal structures.
During the examination, the organs in the abdominal area are systematically evaluated. The following aspects of the organs can be examined in detail:
- Size,
- Structure,
- Margins,
- Parenchymal characteristics,
- Relationship with surrounding tissues
When the upper and lower abdomen are evaluated together, comprehensive information is obtained not only about a single organ but also about the overall condition of the intra-abdominal anatomy.
Which Organs Are Evaluated with Upper and Lower Abdomen USG?
Many abdominal organs and anatomical structures can be evaluated in the same session during the examination.
The main structures evaluated are:
- Liver,
- Gallbladder,
- Bile ducts,
- Pancreas,
- Spleen,
- Kidneys,
- Bladder,
- Major blood vessels,
- Presence of free fluid in the abdomen,
- Soft tissue areas deemed necessary.
The scope of evaluation can be expanded according to clinical findings, and more detailed examination of relevant areas can be performed.
In Which Cases Is Upper and Lower Abdomen USG Performed?
Upper and Lower Abdomen USG can be requested for diagnostic evaluation in many different clinical situations.
The most common reasons for evaluation include:
- Abdominal pain,
- Abdominal bloating,
- Indigestion and digestive system complaints,
- Right or left upper quadrant pain,
- Flank pain,
- Palpable mass in the abdomen,
- Suspected gallbladder disease,
- Evaluation of kidney diseases,
- Examination of liver diseases,
- Abdominal findings requiring follow-up.
Ultrasonography allows simultaneous evaluation of the intra-abdominal organs while investigating the source of the current complaint.
What Does Upper and Lower Abdomen USG Show?
Upper and Lower Abdomen USG;
- Liver,
- Gallbladder and bile ducts,
- Pancreas,
- Spleen,
- Kidneys,
- Bladder,
- Major blood vessels,
- Other assessable abdominal structures
helps in the real-time examination of anatomical and structural features.
What Can Be Evaluated with Ultrasonography?
With ultrasonography, not only the sizes of abdominal organs but also their tissue and structural characteristics can be examined in detail.
During the examination:
- Organ sizes,
- Organ margins and contour characteristics,
- Parenchymal structure,
- Cystic formations,
- Solid lesions,
- Gallbladder and bile ducts,
- Kidney stones and dilations in the urinary system,
- Presence of free fluid in the abdomen,
- Bladder fullness and structural features
can be evaluated.
If necessary, the findings obtained are interpreted together with clinical evaluation, and the following can be planned:
- Follow-up plan,
- Control ultrasonography,
- Advanced imaging,
- Additional laboratory or diagnostic tests
can be planned.
Is Preparation Required Before Upper and Lower Abdomen USG?
The preparation process may vary depending on the area to be examined.
Especially:
- For upper abdomen evaluations, fasting for a certain period may be recommended to improve image quality.
- For lower abdomen and bladder evaluations, a full bladder may be required.
- Different preparation recommendations may be given depending on the scope of the examination.
The necessity and duration of preparation are planned by the physician according to the purpose of the examination.
How Long Does Upper and Lower Abdomen USG Take?
The duration may vary depending on the scope of the examination and the structures to be evaluated. The procedure is usually completed within 15–30 minutes.
Post-Procedure Process
Upper and Lower Abdomen USG is a non-invasive imaging method. There is no recovery period that restricts daily life after the procedure. The person can continue their daily activities on the same day after the examination is completed.
The findings obtained are interpreted together with clinical evaluation. If necessary:
- Clinical follow-up,
- Control ultrasonography,
- Advanced imaging,
- Laboratory tests,
- Other diagnostic methods
can be planned.
Upper and Lower Abdomen USG is one of the fundamental ultrasonographic examination methods that plays an important role in the structural evaluation of intra-abdominal organs, investigation of many abdominal complaints, and guidance of the diagnostic process.
