• Urinalysis is essential. • Most degree that proteinuria must exceed 500mg/day to be considered abnormal for pregnancy. • If the serum creatinine persistently exceeds 0.9mg/dl (75umol/L), then intrinsic renal disease should be suspected. • Ultrasonogaphy provides imaging of renal size and relative consistency,as well as elements of obstruction. • If necessary,cystoscop, intravenous pyelography, or renal biopsy may be considered.
