Clinical implications of acute pelvicaliceal hematoma formation during percutaneous catheter nephrostomy insertion.
OBJECTIVE
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).


CONCLUSIONS
Pelvicaliceal hematoma formation after PCN insertion is not uncommon and is associated with very rare clinical sequelae.
