Background and Aim: CT urography is a single comprehensive modality for the diagnosis of patients suspected with hematuria. Hence, the present study was designed to evaluate the efficacy of role CTU in the diagnosis and assessment of renal lesions in comparison with other diagnostic modalities. Material and Methods: A total of 83 patients suspected with hematuria between 18-75 years of age presented at the Department of Radio-diagnosis, KMC, Manipal University, Mangalore were selected. The patients were subjected to 3 phase CT examination after obtaining informed consent. Patients' demographic details viz. age, gender, and clinical manifestations were recorded. Assessment parameters like sensitivity, specificity, positive predictive value, and negative predictive value were analyzed. Results: The majority of study subjects with hematuria i.e. 28.92% belonged to the age group of 60-70 years with male predominance. The results of the present study revealed that 11 out of 14 cases showed masses confined to the kidney (<7 cm diameter), corresponding to stage T1 RCC according to TMN classification. Cystoscopy was done for 25 cases of which 17 cases showed bladder TCC out of which one was female patient, and all others were male. Gross hematuria is not only a diagnosis. It is a symptom with an underlying cause, which is often serious and 15–28% of patients with gross hematuria have a malignancy in the urinary tract as the underlying cause. When examining patients with gross hematuria, the most common tumor found in up to 20% of patients, is bladder cancer. Other tumors causing gross hematuria are renal cancer, urothelial cell carcinoma (UCC) of the renal pelvis and the ureters, and prostate cancer. The sensitivity and specificity of CTU with regards to renal lesions diagnosis and assessment were reported as 98-100% and 92-100%, respectively. Conclusion: Most of the renal lesions were diagnosed accurately by CTU as compared to other diagnostic modalities. Hence, CTU could be recommended for the precise and accurate diagnosis of renal lesions.
