Highlights
- •Intra-procedural pelvicaliceal hematoma formation occurred in 21% of PCN insertions.
- •There was a very low incidence of clinically significant blood loss, catheter obstruction, or delayed return to baseline renal function in patients with intra-procedural pelvicaliceal hematomas.
- •The results suggest that intra-procedural pelvicaliceal hematoma formation is a relatively benign and self-limited phenomenon.
Abstract
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.
