The procedure described by CPT® Code 50100 involves the transection or repositioning of aberrant renal vessels, which is classified as a separate procedure. Aberrant renal vessels are abnormal blood vessels that can lead to complications such as ureteropelvic junction (UPJ) obstruction. This obstruction occurs when the renal arteries and/or veins, particularly at the inferior pole of the kidney, cross in front of the ureter, resulting in a blockage that can cause hydronephrosis, a condition characterized by the swelling of a kidney due to a build-up of urine. The surgical approach typically involves an anterior incision to provide access to the affected renal vessels, ureter, and kidney. During the procedure, the aberrant vessels are carefully dissected from the surrounding tissues. If it is determined that the kidney receives sufficient blood supply from other renal vessels, the aberrant vessels can be ligated and transected. However, if preservation of these vessels is necessary, vessel loops are strategically placed above and below the intended transection site. The vessels are then transected between these loops and repositioned to alleviate the obstruction at the UPJ. Finally, the vessels are reconnected through anastomosis, the vessel loops are removed, and the surgical site is closed in layers to ensure proper healing.

The procedure described by CPT® Code 50100 is indicated for patients experiencing ureteropelvic junction (UPJ) obstruction due to aberrant renal vessels. This condition may present with symptoms such as:
The procedure for CPT® Code 50100 involves several critical steps to address the aberrant renal vessels and relieve the obstruction:
Post-procedure care following the transection or repositioning of aberrant renal vessels includes monitoring for any signs of complications such as bleeding or infection. Patients may require imaging studies to assess the success of the procedure and ensure that the ureteropelvic junction is functioning properly. Recovery may involve pain management and gradual resumption of normal activities, with specific instructions provided by the healthcare team based on the individual patient's condition and response to surgery.
