Abstract

A system and method of diagnosing kidney syndromes using an intravenous pyelogram (IVP) is described. The system includes an X-ray imaging device and an in-vitro diagnostic (IVD) device. The IVD device is used to identify risk factors such as sensitivity to contrast agents, or to indicate or rule out other syndromes which may have symptoms similar to kidney malfunction. The level of blood components such as creatinine may be used, in conjunction with other medical data and IVD tests, to determine a risk score for the patient. The risk score may be used to recommend modifications to a baseline procedure such as change in the volume or type of contrast agent, the number of X-rays, or the performance of post-procedure dialysis.

Claims

1. A method of performing a diagnostic procedure on a patient, the method comprising:

selecting a diagnostic procedure;

retrieving existing patient medical records;

determining whether appropriate in-vitro diagnostic tests (IVD) have been performed;

performing needed IVD tests;

determining a risk score for the patient; and

selecting procedure steps and parameters based on the patient risk score.

2. The method of claim 1, wherein the diagnostic procedure is an intravenous pyelogram (IVP).

3. The method of claim 2, wherein a factor in determining the risk score is blood creatinine level as measured by an IVD.

4. The method of claim 1, wherein the needed IVD tests include at least one of an IVD test for diagnosis of:

kidney stones, an enlarged prostate, or tumor in the kidney, ureters, or urinary bladder.

5. The method of claim 4, wherein the needed IVD tests include a test for iodine sensitivity.

6. The method of claim 1, wherein the risk score is used to modify at least one of a volume of contrast agent administered, or a period between X-ray exposures.

7. The method of claim 1, wherein when the risk score is very high, a dialysis procedure is performed on the patient after completion of the diagnostic procedure.

8. A computer program product, stored on a computer readable medium, comprising:

instructions for configuring a computer to;

request medical data of a patient from a data base;

receive the medical data from a data base through an interface to a network;

accept an operator input identifying the diagnostic procedure to be planned;

determine a set of IVD tests needed for the procedure, and whether all of the needed tests have are present in the medical data;

request any needed IVD tests that are not present in the medical data and accept the results of the requested IVD tests;

determine a risk score to the patient for the diagnostic procedure; and

recommend changes to the diagnostic procedure based on the risk score.

9. The computer program product of claim 8, wherein the risk score includes at least one of the following factors:

a probability that a syndrome causing patient symptoms has been diagnosed by the performed IVD tests, and a sensitivity of the patient to the contrast agent as determined from one of the received medical data or the performed IVD tests.

10. The computer program product of claim 9, wherein the diagnostic procedure is an intravenous pyelogram (IVP).

11. The computer program product of claim 10, wherein the risk score includes the blood creatinine level as a factor.

12. The computer program product of claim 11, wherein when the creatinine level is very high a post-IVD dialysis procedure is recommended.

13. The computer program product of claim 11, wherein a volume of contrast agent or a number of X-ray exposures is adjusted based on the risk score.

14. A system for performing an intravenous pyelogram (IVP), comprising:

an X-ray device; and

an in-vitro diagnostic device (IVD),

wherein the IVD is used to perform a test for at least one syndrome related to a patient symptoms, and at least one of a type or volume of contrast agent, or a number of X-rays during the IVP is changed from a low risk baseline procedure.

15. The system of claim 14, wherein the IVD is a point-of-service device.

16. The system of claim 14, wherein the IVD is used to perform a test for iodine sensitivity.

17. The system of claim 14, wherein the IVD is used to perform a test for blood creatinine level.

18. The system of claim 17, wherein when the blood creatinine level is very high, the system further comprises a kidney dialysis device.
