Several meanings: Several reasons for not receiving Lasix (furosemide) during mag3 scan. The first reason is that there was no stasis in kidney and Lasix (furosemide) was not necessary to prove presence or lack of kidney obstruction. Another reason is that function of remaining kidney was so impaired that Lasix (furosemide) was not going to offer any additional information. You should ask your doctor for clarification of study results.
