- Initial management is conservative treatment, which consists of bed rest and analgesics.
- Indications for immediate surgical intervention includes a renal pedicle injury, expanding pulsatile hematoma, or polytrauma in an unstable patient.
- Persisting extravasation of urine normally resolves after the placement of a ureteral stent.
- Urinomas usually resolve either with stent placement alone or with percutaneous drainage and stent placement.
- If a perinephric abscess develops, a trial of antibiotics may be attempted if the abscess is less than 3 cm. If the abscess is greater 3 cm, then percutaneous drainage and antibiotics are usually required.
- Catheter embolization may be used to treat pseudoaneurysms or aterio-venous fistulas that develop after the initial trauma.
- The kidney is the most commonly injured organ in the urinary tract.
- Staging of the injury is dependent on depth of parenchymal involvement as well as involvement of collecting and vascular systems.
- Treatment is dependent on staging and related complications.
