Introduction
Hematuria, the presence of blood in the
urine, is a common symptom that can
indicate various underlying conditions.
CT urography is a valuable imaging
modality in the evaluation of hematuria.
This presentation will discuss the role of CT
urography in diagnosing and managing
hematuria.

3. 2
Definition of Hematuria
Hematuria is categorized as either gross
(visible to the naked eye) or microscopic
(detected only under a microscope).
It can be caused by a range of conditions,
including urinary tract infections, kidney
stones, and urological malignancies.
CT urography plays a crucial role in
identifying the cause of hematuria and
guiding further management.

4. 3
Principles of CT Urography
CT urography combines conventional CT
imaging with contrast-enhanced imaging of
the urinary tract.
It provides detailed anatomical information
of the kidneys, ureters, and bladder.
CT urography can detect both structural
abnormalities and functional changes in the
urinary system.

5. 4
Indications for CT Urography in Hematuria
Persistent or recurrent hematuria that requires further evaluation.
High-risk patients with a history of smoking, occupational exposure, or
family history of urological malignancies.
Evaluation of suspected urinary tract stones or other anatomical
abnormalities.

6. 5
Advantages of CT Urography
CT urography is non-invasive and provides high-resolution images of
the urinary tract.
It allows for rapid evaluation of the entire urinary system in a single
imaging session.
CT urography can accurately detect tumors, stones, and other
pathologies causing hematuria.

7. 6
Technique of CT Urography
Patients typically undergo a pre-contrast
scan followed by intravenous contrast
administration.
Delayed imaging is performed to visualize
contrast excretion and assess the collecting
system.
Multiplanar reconstructions and 3D images
can enhance the diagnostic accuracy of CT
urography.

8. 7
Diagnostic Accuracy of CT Urography
CT urography has a high sensitivity and specificity for detecting
urological malignancies.
It can accurately identify renal masses, urothelial tumors, and other
sources of hematuria.
CT urography is particularly useful in ruling out significant pathology
in patients with hematuria.

9. 8
Limitations of CT Urography
CT urography involves radiation exposure,
which may be a concern in certain patient
populations.
It may not be suitable for patients with
impaired renal function or contrast
allergies.
In some cases, additional imaging
modalities such as MRI or cystoscopy may
be needed for further evaluation.

10. 9
Clinical Impact of CT Urography
CT urography can aid in early detection
and staging of urological malignancies.
It can guide treatment decisions and
surveillance strategies for patients with
hematuria.
The information obtained from CT
urography can help improve patient
outcomes and reduce unnecessary
invasive procedures.

Conclusion
In conclusion, CT urography plays a vital
role in the evaluation of hematuria by
providing detailed imaging of the urinary
tract.
It is a valuable tool for identifying the
underlying cause of hematuria and guiding
appropriate management.
By combining anatomical and functional
information, CT urography can help
clinicians make informed decisions and
improve patient care.
