After mesalazine withdrawal, renal function was quickly restored. Incontrast with published case reports, the onset of renal impairment occurred very early.

The diagnosis ofrenal impairment was supported by urine analysis (both semi-quantitative and quantitative) and dynamic renalisotope scanning.
