UNLABELLED: Every year 50,000 patients receive a stem cell transplantation worldwide, but there is lack of data pertaining to urological complications.
METHODS: We performed a retrospective analysis of all adult patients undergoing their first allogenic stem cell transplantation from January 2011 to June 2013 in our institution. Statistical tests performed were Pearson's correlation, chi-square testing and logistic regression using SPSS 22.0.
RESULTS: We identified 39 patients (22 males, 17 females). Twenty four patients (61.5%) had a urological complication. Most frequent urologic complications were bacterial urinary tract infection (n = 13; 33.3%), acute renal failure (n = 6; 15.4%) and BK virus-associated haemorrhagic cystitis (n = 5; 12.8%). BK viruria was detected in 12 patients (30.8%). We observed an association of creatinine increase (about 20 µmol/l at time of onset of BK viruria) with BK viruria (Pearson's correlation 0.64; p = 0.01), and BK viruria is significantly linked to acute renal failure (Pearson's correlation 0.35; p = 0.029). In univariate regression, BK viruria is significantly linked to urological complication (p = 0.025).
CONCLUSIONS: We suggest that BK virus infection during stem cell transplantation can lead to BK virus associated nephropathy, which is so far only known from patients after kidney transplantation.
