Abstract:
CT urography is emerging to be the standard imaging tool for the evaluation of patients with
urological manifestations such as hematuria and renal colic as it allows comprehensive
evaluation of the upper and lower urinary tract. Accurate and prompt diagnosis is very crucial
for best patient care hence imaging plays a major role.
Broad Objective:
This study aimed to determine the role of CT Urography in adult patients with urological
manifestation at MNH from august 2020 to January 2021
Methodology:
This study was a hospital-based descriptive retrospective and prospective study of adults aged
18 years and above. It was done at Muhimbili National Hospital in the Radiology Department
using a structured data collection tool. The information obtained includes Socio-demographic
information, clinical information, and CT Urography findings. Comparison of CTU results
with other clinical results (Endoscopy: cystoscopy and ureteroscopy, open surgery and
urinalysis and histopathological results (where available). Data analysis was done using SPSS
and summarized using tables and figures.
Results
Study participants included were 106(54.1%) males and 90 (45.9%) females. The 2 most
common symptoms were renal colic 156(79.6%) and hematuria 43(21.9%). CTU depicted
many urinary tract abnormalities including renal stones 43 (21.9%), Ureteric stones
25(12.8%). Bladder stone 6(3.1%), solid renal mass 23(11.7%), bladder mass 8(4.1%), 95
cases of other urinary system disorders, and 24 extra-urinary findings. Among the 120 patients
who underwent surgery, CTU correctly diagnosed all urinary tract stones 53 however one false
positive was encountered (sensitivity 100%, specificity 98.5%)
Conclusion
CTU is a useful modality for detecting many urinary tract abnormalities. It has exceptional
capabilities with high sensitivity and specificity in detecting urinary tract stones. In addition,
vi
CTU has the advantage of detecting extra-urinary and incidental findings which may not be
suspected clinically.
Recommendation
Sensitization for prompt referral of patients with hematuria and renal colic to a specialized
urological clinic for proper workup and management. CTU should be considered the primary
imaging modality in the evaluation of high-risk patients with hematuria
