Mubarak will be tried on charges of corruption and intentionally killing protesters during nearly three weeks of demonstrations in February.
Government physicians say Mubarak is too ill to be imprisoned until the start of the trial. He remains in custody at a hospital in Sharm el-Sheik.
Since Mubarak's ouster ongoing revolts have swept Yemen, Libya and Syria, but entrenched leaders in those countries still cling to power and have been responsible for widespread violence and killings of their own people who are demanding democratic reforms.
Mubarak could face the death penalty if convicted. At least 846 protesters were killed during the 18-day revolt.
