Subcapsular Haematoma in Renal Transplant Post Biopsy: A Critical Complication

Subcapsular haematomas (SCHs) are uncommon but critical complications following renal transplant biopsy. These haematomas occur when blood collects beneath the renal capsule, often due to trauma, surgical interventions or vascular injuries. SCHs can range in severity from asymptomatic to causing serious complications, including graft dysfunction. Early detection is crucial to prevent graft ischemia and complications such as ‘Page kidney’, which may necessitate surgical intervention. This case study details a 50‐year‐old female renal transplant patient who developed a subcapsular haematoma following a renal transplant biopsy. Although the haematoma was initially difficult to detect due to its isoechoic appearance, advanced imaging techniques such as B‐flow and high‐frequency ultrasound probes assisted in the accurate diagnosis. Despite concerns about vascular compromise and the potential for Page kidney, the haematoma did not progress to this severe complication. The case underscores the importance of timely diagnosis and tailored management approaches, especially in complex cases where concurrent rejection and vascular changes are present. This study highlights the role of ultrasound, particularly B‐flow imaging, in managing post‐transplant complications.
