According to TMZ, Gene Simmons is recovering after undergoing a successful kidney stones surgery.
Sources close to the KISS bassist/vocalist tell the site that Gene was admitted into Cedars-Sinai Hospital early Tuesday morning to undergo a medical procedure that should help get rid of the stones. The non-invasive operation only took about an hour to complete and involved inserting a stent in his urethra to help him pass his stones. The stent is expected to be removed in a week.
Last month, KISS postponed its concert in Salt Lake City. At the time, Simmons tweeted that he had to fly to Los Angeles "to do a medical procedure." He added: "Nothing serious. But it must be taken care of now."
Earlier last month, KISS postponed its shows in Oakland and Los Angeles. The date at Oakland Arena, originally set for September 16, is now listed on the venue web site as March 6. The date at Staples Center in Los Angeles, originally set for September 20, now takes place March 4.
The only reason given for moving the Oakland and Los Angeles performances was "unforeseen scheduling issues."
KISS's current lineup consists of original members Simmons and Paul Stanley, alongside later band additions, guitarist Tommy Thayer (since 2002) and drummer Eric Singer (on and off since 1991).
Formed in 1973 by Stanley, Simmons, drummer Peter Criss and lead guitarist Ace Frehley, KISS staged its first "farewell" tour in 2000, the last to feature the group's original lineup.
The End Of The Road" farewell tour launched in January and is expected to run through at least the end of 2020.
