Johannesburg, Mar 11 (IANS): Former South African president Nelson Mandela was discharged from hospital Sunday after undergoing a medical check-up, the presidency said.

The 94-year-old was admitted into a hospital Saturday, for the second time in three months, for a scheduled medical check-up, Xinhua reported.

Mandela has returned to his Johannesburg home following "a successful medical examination at a Pretoria hospital," a spokesperson Mac Maharaj said.

"The doctors have completed the tests. He is well and as before, his health remains under the management of the medical team," he added. "We continue to appeal for privacy for Madiba (as Mandela is affectionately called) and his family."

On Dec 8, 2012, Mandela was taken into a Pretoria hospital for a lung infection and gallstones. He underwent a successful surgery to have the gallstones removed after doctors attended to his lung infection.

He was discharged from hospital Dec 26 to undergo home- based high care at his Houghton home. This was Mandela's longest hospital stay since 2001 when he underwent seven weeks of radiotherapy after being diagnosed with prostate cancer.

Mandela served as South African president from 1994 to 1999 and spent 27 years in prison before being elected the first black president in the country after the end of apartheid.
