This study demonstrates the normal technetium-99m diethylenetriaminepentaacetic acid ((/sup 99m/Tc)DTPA) renal scan in pregnant patients with transplanted kidneys. Five pregnant renal transplant patients had seven (/sup 99m/Tc)DTPA renal studies to assess allograft perfusion and function. All scans showed the uteroplacental complex. The bladder was always compressed and distorted. The transplanted kidney was frequently rotated to a more vertical position. In all patients allograft flow and function were maintained. There was calyceal retention on all studies and ureteral retention activity in three of five patients. Using the MIRD formalism, the total radiation absorbed dose to the fetus was calculated to be 271 mrad. This radiation exposure is well within NRCP limits for the fetus of radiation workers and an acceptable low risk in the management of these high risk obstetric patients.
