In a 42 U.S.C. section 1983 alleging that a correctional officer and two prison nurses violated plaintiff's Fourth and Eighth Amendment rights by forcing him to undergo catheterization to avoid prison discipline when he could not provide a urine sample for a random drug test, summary judgment for defendants is affirmed, although on alternate grounds in part, where: 1) the district court erred in concluding that defendant-correctional officer violated plaintiff's Fourth Amendment rights because he presented no evidence that she was personally responsible for any involuntary catheterization that occurred; 2) summary judgment for nurses was proper; and 3) the allegations fell short of raising a genuine issue of material fact as to whether the defendants acted with a sufficiently culpable state of mind to support an Eighth Amendment brutality claim.
