Lamar Odom may be on the road to recovery, but he's not out of the woods just yet. While most of the former NBA star's body is healing from his recent collapse, his kidneys are said to be showing a continued decline in function. He has been placed on dialysis, and now, his doctors are reportedly looking into new avenues.

TMZ reports that many of Odom's organs have begun the upward climb to recovery. Sources close to Khloé Kardashian's estranged husband, however, have said that "his kidneys are shot." Doctors at Cedars-Sinai Medical Center, the Los Angeles hospital where he was recently moved, currently have him on six hours of dialysis a day. The gossip site reports that doctors are considering a kidney transplant.

Odom, 35, was airlifted to Cedars-Sinai from Sunrise Hospital in Las Vegas around 8 p.m. EDT Monday. Prior to the move, doctors ran several tests, including a swallow test, concluding that he had made several significant improvements. Odom was able to verbally communicate to some extent and was also said to be using hand signals. He was reportedly able to move from bed with some assistance. Doctors at Cedars-Sinai reportedly plan to run brain tests in an effort to determine once and for all how much damage his stroke caused to his brain.

Shortly after Odom's transfer Monday night, Khloé's brother, Rob Kardashian, who has been in hiding for the better part of the last few years, was spotted in public. As we previously reported Rob, 28, was seen driving Khloé's Range Rover. It remains unclear where he was headed, but many have speculated that Odom being hospitalized closer to home may have drawn him out into public. Rob has been outspoken in his support of Odom, though he was one of the only members of the Kardashian clan who did not fly to Las Vegas to be at his bedside. He did, however, post a message of hope on Instagram.

Neither the Kardashians nor members of Odom's camp have released an official statement about his condition.
