Differential Diagnosis
The patient's urinalysis results show a combination of findings, including the presence of red blood cells (RBC), bacteria, yeast, trace blood, and protein in the urine, along with elevated CRP levels. Based on these results, the differential diagnosis can be categorized as follows:
- Single Most Likely Diagnosis
- Urinary Tract Infection (UTI): The presence of moderate bacteria, RBCs, and trace blood in the urine, along with elevated CRP, strongly suggests a UTI. The presence of yeast could indicate a fungal UTI, but bacterial UTIs are more common.
- Other Likely Diagnoses
- Kidney Stone: The presence of RBCs in the urine could be indicative of a kidney stone, which could also cause a UTI.
- Interstitial Cystitis: This condition could cause RBCs and protein in the urine, but it is less likely given the presence of bacteria.
- Prostatitis: In male patients, prostatitis could cause similar symptoms, including UTI-like symptoms and elevated CRP.
- Do Not Miss Diagnoses
- Sepsis: Although less likely, the combination of UTI symptoms and elevated CRP could indicate sepsis, particularly if the patient shows signs of systemic illness.
- Pyelonephritis: An upper urinary tract infection that could lead to sepsis if not treated promptly.
- Tuberculosis (TB) of the Urinary Tract: Although rare, TB can cause similar symptoms, including RBCs and protein in the urine, and would be a critical diagnosis not to miss.
- Rare Diagnoses
- Malignancy: Certain types of cancer, such as bladder or kidney cancer, could cause RBCs and protein in the urine, but this would be less likely given the presence of bacteria and yeast.
- Glomerulonephritis: An inflammation of the glomeruli in the kidneys that could cause RBCs and protein in the urine, but this would typically have other associated symptoms and findings.
