Differential Diagnosis for Moderate Epithelial Cells in Urinalysis
Single Most Likely Diagnosis
- Urinary Tract Infection (UTI): The presence of moderate epithelial cells in urinalysis can be indicative of a UTI, as the infection can cause irritation and shedding of the epithelial lining of the urinary tract.
Other Likely Diagnoses
- Dehydration: Inadequate hydration can lead to concentrated urine, which may cause irritation to the urinary tract epithelium, resulting in the presence of epithelial cells in the urine.
- Kidney Stones: The passage of kidney stones can cause irritation and damage to the epithelial lining of the urinary tract, leading to the presence of epithelial cells in the urine.
- Cystitis: Inflammation of the bladder (cystitis) can cause shedding of epithelial cells, which may be detected in urinalysis.
Do Not Miss Diagnoses
- Bladder Cancer: Although less common, bladder cancer can cause the presence of epithelial cells in the urine. It is crucial to rule out this diagnosis, especially in patients with risk factors such as smoking or exposure to certain chemicals.
- Kidney Disease: Certain kidney diseases, such as interstitial nephritis or pyelonephritis, can cause epithelial cell shedding and should not be missed due to their potential for significant morbidity.
Rare Diagnoses
- Tubulointerstitial Nephritis: A rare condition characterized by inflammation of the tubules and interstitium of the kidneys, which can cause the presence of epithelial cells in the urine.
- Papillary Necrosis: A rare condition characterized by necrosis of the renal papillae, which can cause the presence of epithelial cells in the urine.
- Urinary Tract Malformations: Congenital malformations of the urinary tract, such as ureteropelvic junction obstruction, can cause epithelial cell shedding and may be detected in urinalysis.
