Abstract:
Background: The presence of more than or equal to 3 RBC/HPF in the sediment is defined as haematuria. It can be symptomatic or asymptomatic. Painless haematuria is most often caused by carcinoma, while painful haematuria is often seen secondary to urolithiasis or infection. The procedure entailed in detection of microscopic haematuria and gross haematuria is the same. But in the microscopic haematuria the focus is on the glomerular causes. In the diagnosis of haematuria radiology plays a very important role. Radiological investigation of upper urinary tract is usually by IVU but has been gradually replaced over the last decade by MDCT Urography as the gold standard imaging modality. CT-Urography (CTU) can accurately identify benign causes of haematuria in about 33-43% cases. The overall sensitivity is 92-100% is for identifying benign causes, while 89-97% gives the specificity for benign causes, especially calculi. Hence, we performed a study to compare the CT and USG findings for haematuria.
Methods: The study included 50 of the patients diagnosed with microscopic or macroscopic haematuria and those above the age of 18 years. We excluded those patients with patients whose serum creatinine value was above 1.5 mg/dL, those that are at a risk for allergic reactions to contrast, those with neoplasms and pregnant patients.
Results- In the present study, we found that the sensitivity and specificity of USG was 87.92% and 86.52% respectively. However, for CT urography, it was 97.62% sensitivity and 92.34% specificity. This shows that CT is more sensitive for identifying benign lesions in the KUB region as compared to USG.
Conclusion- CT urography is more sensitive and specific for benign lesions when compared to USG.
