title: Polyoma virus nephropathy, first reported case in Saudi Arabia.
abstract: Polyoma virus nephropathy (BK virus) is being recognized as an important cause of graft failure. It is usually confused with acute rejection. No cases have been reported from the kingdom of Saudi Arabia. We report a case of a Saudi gentleman, who was transplanted outside the country, with persistently elevated creatinine and urethral stenosis. He was treated for acute rejection on more than one occasion with no significant improvement in his renal function. Polyoma virus nephropathy was diagnosed by detecting the virus DNA by the Poly chain reaction technique (PCR). The patient's renal function stabilized after the calcineurin inhibitors were discontinued.
