Lee, Lucero, Macalintal, Magallanes, Maningas, Ombao, Pacifico Diagnostics
Initial Laboratory Tests • CBC • leukocytosis • Low Hgb, low Hct – bleeding (obstructive uropathy) • ESR • CRP
Urinalysis • Pyuria • With bacteriuria (≥105/ml): highly sensitive indicator of UTI • Sterile pyuria • Atypical organisms: C. Trachomatis, U. Urealyticum, M. Tuberculosis • Non-infectious urologic conditions: calculi, anatomic abnormality, nephrocalcinosis, VUR, interstitial nephritis, polycystic disease • Gram-stained uncentrifuged urine (for empiric choice of antibiotic) • Leukocyte casts which form casts – characteristic of acute pyelonephritis • Hematuria – urolithiasis
Serum BUN and Creatinine • determine (reversible) renal damage
Two 24-h urine collections • calcium, sodium, phosphorus, magnesium, oxalate, uric acid, citrate, sulfate, creatinine, pH, and total volume
Comprehensive Metabolic Panel • serum calcium, uric acid, and phosphorus; parathyroid hormone level
Urine culture and sensitivity • No longer requested for uncomplicated acute cystitis • criterion standard for evaluation of a urinary tract infection (UTI) during pregnancy • results are often unavailable at the time of treatment
Blood culture • Severely ill patients
Imaging • The total dosage of ionizing radiation should not exceed 3-5 rads during the course of pregnancy
UTZ • cheap; no exposure to radiation or dyes • stones may not be identified due to hydronephrosis in pregnancy • typical acoustic shadowing
X-ray • one-shot pyelogram (ie KUB) • to identify stones obscured in renal ultrasound • can deliver 0.4-1 rad
Helical CT scan • gold standard for urolithiasis in non-pregnant patients
Other Procedures • evaluation of fetal status: FHT
