Afghanistan's President Ashraf Ghani successfully underwent a prostate operation at Kabul's Daud Khan Military Hospital.
"I would like to thank all the doctors and nurses of this hospital for successfully completing my operation," he wrote on Twitter on Tuesday.
The procedure comes ahead of a conference in Turkey to finalise talks between the internationally recognised government headed by Mr Ghani and the Taliban.
Mr Ghani is set to propose a three-part peace proposal at the dialogue this month.
His plan is poised to counter proposals by Washington – which Mr Ghani's government had previously rejected – that envisage immediately drawing up a new legal system for an interim administration to include Taliban representatives.
A document seen by Reuters shows Mr Ghani's "Reaching an Endstate" proposal will include, in the first phase, a consensus on a political settlement and an internationally monitored ceasefire.
The second phase will be holding a presidential election later this year and the establishment of a “government of peace” and implementation arrangements for moving towards the new political system.
The third phase of the president's plan will involve building a “constitutional framework, reintegration of refugees and development” for Afghanistan moving forward.
The Taliban rejected Mr Ghani's election proposition.
"Such processes [elections] have pushed the country to the verge of crisis in the past," Taliban spokesman Zabihullah Mujahid said.
"We will never support it."
