Non-urologic flank pain: a diagnostic approach.

Area of Science:

• Nephrology
• Urology
• Pain Management
• Psychiatry

Background:

• Reno-ureteral pain can be mimicked by referred pain from adjacent structures or conditions with shared innervation.
• Mental illness can also cause or worsen flank pain, complicating diagnosis.
• Various non-urologic conditions, such as herniated discs, neuralgia, arthritis, and pancreatitis, can present as flank pain.

Purpose of the Study:

• To emphasize the importance of a systematic evaluation for flank pain.
• To highlight the differential diagnoses for flank pain beyond the reno-ureteral system.
• To advocate for a structured approach to prevent misdiagnosis and unnecessary procedures.

Main Methods:

• Utilized case examples of diverse conditions presenting with flank pain.
• Implemented patient screening using the Cornell medical index and a urology questionnaire.
• Directed physical examination, radiographic studies, laboratory tests, and psychiatric evaluations based on initial screening.

Main Results:

• Demonstrated that flank pain can stem from a wide array of conditions, including musculoskeletal, neurological, and psychiatric disorders.
• Showcased the utility of standardized questionnaires in guiding diagnostic workups.
• Highlighted the potential for misdiagnosis and unnecessary urologic interventions without a systematic approach.

Conclusions:

• An orderly and comprehensive evaluation is essential for accurately diagnosing the cause of flank pain.
• Systematic patient screening and targeted investigations can prevent unnecessary urologic operations.
• Considering referred pain and comorbidities like mental illness is critical in flank pain assessment.
