Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents with intermittent flank pain and an incidentally noted perirenal cyst on abdominal imaging. The urologist evaluates imaging (CT or ultrasound) that localizes a symptomatic cyst arising from the perinephric tissues. After informed consent, the patient is scheduled for an operative excision of the cyst under general anesthesia. Intraoperative workflow includes surgical exposure of the retroperitoneum, identification of the cystic lesion adjacent to the kidney, careful dissection to separate the cyst from renal capsule and surrounding structures, removal of the cyst wall, hemostasis, and placement of drains if indicated. Specimens are sent to pathology when indicated. Postoperative monitoring occurs in the PACU with routine pain control, wound care instructions, and follow-up imaging or clinic visit to assess healing and rule out recurrence or complications such as bleeding or infection.
