Renal disease and pregnancy

Asymptomatic bacteriuria in pregnant women has been linked to an increased incidence of pyelonephritis, preeclampsia, hypertension, intrauterine growth retardation and premature delivery. Pyelonephritis and cystitis require different antibiotics and dosages in pregnant patients. Renal calculi can be difficult to detect during pregnancy. Women with preexisting renal disease usually do well during pregnancy if renal function is preserved and hypertension is not present.
