Joint List MK Ahmad Tibi was rushed to the hospital on Sunday to remove kidney stones after being diagnosed with the condition over the weekend.
Tibi was taken to the Hadassah Ein Kerem Medical Center in Jerusalem after feeling unwell. There, he underwent emergency surgery to remove the kidney stones.
The surgery was successful, according to the hospital, and Tibi remained under observation.
On Friday, doctors at Hadassah made the diagnosis after running a series of tests. They said Tibi would have to return early this week for additional monitoring and tests. But after feeling unwell again Sunday, he underwent immediate surgery.
Ra’am chairman Mansour Abbas was hospitalized and forced to undergo surgery for the same condition in April.
Tibi, 62, is one of the longest-serving Knesset members, having entered parliament in 1999. He now heads the two-member Ta’al faction of the Joint List alliance of mostly Arab parties.
