Purpose:
To determine the clinical implications of acute pelvicaliceal hematoma formation during percutaneous catheter nephrostomy (PCN) insertion.
Methods:
Collecting system hematoma burden was retrospectively assessed for 694 PCN insertions in 502 patients.
Results:
Pelvicaliceal 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).
Conclusion:
Pelvicaliceal hematoma formation after PCN insertion is not uncommon and is associated with very rare clinical sequelae.
