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

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.
