Partial pelviureteric junction obstruction secondary to BK virus infection early posttransplantation - A case report

Abstract

A 63-year-old female presented to our hospital with progressive allograft dysfunction, declining urine output and fluid overload. She had undergone a second transplant 4 months before. Her evaluation revealed partial pelviureteric obstruction in her ultrasound. She underwent a renal biopsy which revealed BK virus infection. The pelviureteric obstruction improved with oral diuretics and her mycophenolate sodium was discontinued. The case illustrates a rare urological manifestation of BK virus infection which can present with symptomatic allograft dysfunction early posttransplantation.
