CPT® Code 50380

Renal autotransplantation, as described by CPT® Code 50380, is a surgical procedure in which a patient's kidney is removed from its original anatomical location and reimplanted into a different site, typically the parapsoas fossa. This procedure is performed when there is a need to relocate the kidney due to various medical conditions affecting its function or position. The process begins with the identification and incision of the lateral line of Toldt, which allows for the mobilization of the peritoneum over the kidney, enabling visualization of its anterior surface. The colon is then mobilized and repositioned medially to provide better access to the kidney. During the procedure, the surgeon carefully dissects the kidney from its surrounding structures, including the colorenal ligaments and Gerota's fascia, while ensuring that the ureter and vascular structures are adequately retracted to expose the renal hilum. The lower pole of the kidney is partially mobilized, and the renal artery and vein are meticulously dissected free from surrounding tissues. It is crucial to leave certain attachments intact to prevent torsion and vascular damage. After the kidney is removed, it is prepared for reimplantation, which involves creating an incision in the lower abdomen to access the retroperitoneal space and the iliac vessels. The anastomosis of the renal artery and vein to the iliac vessels is a critical step in this procedure, ensuring proper blood flow to the reimplanted kidney. The ureter is also anastomosed to the bladder, with careful attention to the length and orientation to maintain patency. Throughout the procedure, drains may be placed as necessary, and the incisions are closed to complete the surgery. This complex surgical intervention requires a thorough understanding of renal anatomy and vascular connections to ensure successful outcomes for the patient.
