PurposeTo determine the clinical implications of acute pelvicaliceal hematoma formation during percutaneous catheter nephrostomy (PCN) insertion.MethodsCollecting system hematoma burden was retrospectively assessed for 694 PCN insertions in 502 patients.ResultsPelvicaliceal hematoma formation occurred in 146 kidneys (21%) in 136 patients. Clinically significant blood loss occurred in 3 patients with hematomas within one week compared to 4 patients without hematomas (p=0.39). Twenty-four patients with hematomas underwent catheter exchange within one week, compared to 55 patients without hematomas (p=0.49).ConclusionPelvicaliceal hematoma formation after PCN insertion is not uncommon and is associated with very rare clinical sequelae.
