Prognosis, management and outcome of obstructive renal disease in pregnancy.

The diagnosis and management of obstructive lesions of the urinary tract in pregnancy are hindered by lack of criteria for performing intravenous pyelography (IVP). The majority of obstructive lesions are caused by the gravid uterus; however, an important treatable cause is urinary tract calculi. In order to establish valid criteria for performing IVP in pregnancy, the intravenous pyelograms from 11 pregnant patients with urinary tract symptoms over a six-year period were evaluated. The clinical indications for urography, management of patients with urinary tract obstruction and the pregnancy outcome were studied and compared to those cases reported in the literature.
