Methiodal sodium, a radio-opaque medium, was formerly used for the examination of the urinary tract. Its use was associated with muscle spasms presumed to result from irritation of motor nerve roots in the spinal canal. This led to its withdrawal in Sweden in 1975 when a safer alternative became available. Preparations containing methiodal sodium were subsequently withdrawn worldwide by the manufacturer.
