Haematopoietic stem cell transplantation (HSCT) is a now widely used therapy both in the treatment of haematolymphoid malignancies as well as other malignant or autoimmune diseases. Renal impairment is an important problem after HSCT, yet its pathophysiology still needs more investigation, especially regarding the correlation of clinical findings and morphologic changes.


We retrospectively analysed indication renal biopsies and autopsies after HSCT of the HSCT patient cohort of the University Hospital of Basel, Switzerland. Data of patients’ characteristics were retrospectively collected from the clinical records.


The pathology reports of 17 indication biopsies and 137 autopsies were analysed. In the autopsy cohort, the most common changes were due to acute kidney injury (55/137) most likely as a consequence to the deteriorated state of the patients and thrombotic microangiopathy (14/137). In the indication biopsy cohort the most common changes were therapy related (12/17), with thrombotic microangiopathy (5/17) and Calcineurin-Inhibitor toxicity (4/17) representing the majority within this category.


This study gives a comprehensive overview on potential renal complications in HSCT patients and broadens the spectrum of diseases which have to be expected to occur in this special clinical setting.
