Objective:

To analyze the ultrasonic diagnosis of carcinoma of the renal pelvis

and compare the ultrasonic results with computed tomography (CT) results.

Methods:

The data of 45 cases with carcinoma of the renal pelvis confirmed by ultrasound

CT or operation pathology were analyzed. The diagnostic accuracies of ultrasound and CT were compared.

Results:

Among 45 cases

ultrasound correctly diagnosed 25 cases with carcinoma of the renal pelvis. The accuracy was 55.56% (25/45). CT correctly diagnosed 34 cases with carcinoma of the renal pelvis

1 case with tuberculosis

and 1 case with renal cell carcinoma. The accuracy was 80.00% (36/45). There was statistically significant difference between the two methods (

P

0.05).

Conclusion:

Ultrasound is an important preliminary

screening method in the diagnosis of carcinoma of the renal pelvis. But the detection rate is restrained due to various influencing factors. The combination of ultrasound and CT can improve the detection rate of early diagnosis.
