핵심 개념

• Ureteral Anastomosis — This is a surgical procedure that connects two segments of the ureter after injury or resection, restoring continuity and function to allow normal urine flow from the kidney to the bladder.
• Ureteral Stent — A thin tube inserted into the ureter to provide internal support, maintain patency, prevent strictures, and ensure urine drainage during the healing process after trauma or surgery.
• Ureteral Trauma — Injury to the ureter caused by external forces such as penetrating or blunt trauma, which can lead to partial or complete rupture, potentially resulting in urine leakage, infection, or long-term complications like stenosis.
• Urinary Extravasation — The leakage of urine from the urinary tract into surrounding tissues, often due to ureteral injury, which can cause inflammation, infection, and abscess formation if not promptly managed.
• Percutaneous Nephrostomy — A minimally invasive procedure where a catheter is inserted through the skin into the kidney to drain urine temporarily, used in cases of ureteral obstruction or as an adjunct before definitive repair, but not as a sole treatment for ureteral rupture.
