Which postoperative complication is defined as an encapsulated lymph collection that occurs after renal injury or surgery?

• A. Lymphocele
• B. Urinoma
• C. Pyonephrosis
• D. Hydronephrosis

Answer: (A)

A lymphocele arises when renal surgery or injury disrupts nearby lymphatic channels and lymph leaks into a potential space, becoming organized into a discrete, fibrous-walled fluid collection. The term encapsulated reflects this well-defined, contained pocket rather than a free urine or pus collection. It is a postoperative complication tied to the kidney region because the disruption of lymphatics during renal procedures is the trigger. This is different from a urinoma, which results from leakage of urine from the urinary tract and typically has a fluid that may communicate with the collecting system and, if aspirated, shows urine characteristics. Pyonephrosis is pus within a dilated, obstructed collecting system, and hydronephrosis is simply dilation of the renal pelvis and calyces from obstruction, not a lymphatic leak. Thus, the encapsulated lymph collection after renal injury or surgery best fits the description of a lymphocele.
