    Study Notes

    Urinalysis and UTI Diagnosis

    • WBCs in urine are quantified as the number of cells per high power field; more than 5 RBCs/HPF is abnormal.
    • Presence of bacteria in urine microscopy typically indicates a UTI, but in asymptomatic cases, may result from poor collection technique.
    • Nitrites are the most specific and predictive indicator for diagnosing UTIs; leukocyte esterase, WBCs, and bacteria lack specificity.

    Serum Biochemical Findings

    • Low serum bicarbonate may indicate renal failure or renal tubular acidosis.
    • Low serum albumin can suggest liver disease, malnutrition, or nephrotic syndrome if a new finding.

    Immunology and Renal Disease

    • Antinuclear antibodies and anti-double-stranded DNA antibodies can indicate renal disease related to systemic lupus erythematosus (SLE).
    • Antineutrophil cytoplasmic antibodies (ANCAs) are linked to glomerulonephritis due to systemic vasculitis.

    Renal Biopsy Indications

    • Recommended for cases of acute or chronic kidney injury with uncertain etiology, nephrotic syndrome unresponsive to treatment, and renal transplant dysfunction.
    • Rarely indicated for isolated hematuria or low-grade proteinuria without renal function impairment.

    Contraindications for Renal Biopsy

    • Disordered coagulation or thrombocytopenia complicates procedure and visualization of renal parenchyma.

    Renal Cysts on Ultrasound

    • Ultrasound findings of thin-walled, anechoic lesions with posterior acoustic enhancement indicate a renal cyst.

    Ultrasound in Chronic Kidney Disease (CKD) vs Acute Kidney Injury (AKI)

    • CKD may appear as increased parenchymal echogenicity and loss of corticomedullary differentiation on ultrasound.
    • Doppler imaging assesses blood flow; a resistivity index > 0.7 can suggest acute tubular necrosis or transplant rejection.

    Edema Pathophysiology

    • Edema caused by increased hydrostatic pressure, decreased oncotic pressure, increased capillary permeability, or lymphatic obstruction.
    • Common causes include kidney failure, heart failure, nephrotic syndrome, cirrhosis, and certain medications.

    Oliguria Considerations

    • Bladder enlargement in older men may suggest prostatic enlargement as a cause of oliguria or anuria.
    • Post-anesthesia urinary retention risks may be heightened in those with pre-existing prostatic issues.

    Polyuria Definition and Investigation

    • Polyuria is defined as urine excretion exceeding 3 liters in 24 hours.
    • Investigations include measuring urea, creatinine, electrolytes, and conducting 24-hour urine collections for severity assessment. Nocturnal polyuria suggests a pathological cause.
