The selection of patients for excretory urography

Area of Science:

• Radiology
• Urology
• Diagnostic Imaging

Background:

• Excretory urography is a key diagnostic tool in urology.
• Identifying appropriate indications is crucial for cost-effective patient care.
• Previous studies have not definitively established low-yield indications for this procedure.

Purpose of the Study:

• To evaluate the diagnostic yield of various clinical indications for excretory urography.
• To determine if any indications for excretory urography could be considered low-likelihood.
• To assess the cost-effectiveness and efficacy of patient referral for excretory urography.

Main Methods:

• Retrospective analysis of 1,622 patient cases undergoing excretory urography.
• Comparison of presenting symptoms, signs, and laboratory findings with radiographic results.
• Calculation of the probability of disease association for each indication.

Main Results:

• No "low-likelihood" indications for excretory urography were identified.
• Eliminating any of the studied indications would have led to the missed diagnosis of many patients with demonstrable disease.
• The cost of case-finding was low, and patient referral efficacy was high.

Conclusions:

• All evaluated indications for excretory urography were associated with a significant chance of detecting disease.
• Current indications for excretory urography are effective and should not be eliminated without risking diagnostic omissions.
• The procedure demonstrates high efficacy in patient referral and cost-effective case-finding.
