Patient's question:
Detailed medical condition and consultation purpose: During pregnancy, the urinalysis showed squamous epithelial cells at a count of 10. Previously, cervical erosion of degree 1 was detected. Is this a problem?Doctor's answer:
In urine, the presence of epithelial cells needs to be judged based on their specific shapes to determine their origin. Squamous epithelial cells: originate from the anterior urethra. They appear in large numbers during urethritis. Large round epithelial cells: originate from the superficial layer of the bladder epithelium and are occasionally seen in normal urine. They peel off in sheets during cystitis. Small round epithelial cells: originate from the renal tubules. They are most common during acute pyelonephritis and glomerulonephritis, and their occurrence in clusters indicates tubular necrotic lesions. Tail-shaped epithelial cells: originate from the renal pelvis, but can also come from the ureters or bladder neck. Inflammation of the renal pelvis, ureters, or bladder neck can cause them to peel off in sheets.
