CPT® Code 53405

1. Indications

The procedure of urethroplasty, specifically the second stage represented by CPT® Code 53405, is indicated for patients who have undergone the first stage of urethroplasty and require reconstruction of the urethra due to various conditions. These conditions may include:

• Urethral Stricture: A narrowing of the urethra that can obstruct urine flow.
• Urethral Diverticulum: An abnormal pouch or sac that forms in the urethra.
• Urethral Fistula: An abnormal connection between the urethra and another structure, such as the skin or vagina.

2. Procedure

The second stage of urethroplasty involves several critical procedural steps that ensure the successful reconstruction of the urethra. These steps include:

• Step 1: Once the graft has healed and the epithelial tissue has vascularized, the surgeon begins by excising the vascularized epithelial tissue using longitudinal incisions on each side of the graft. This step is crucial to prepare the tissue for the formation of the neourethra.
• Step 2: The proximal and distal ostia, which are the openings of the urethra, are calibrated to ensure they are of appropriate size for the reconstruction. This calibration is essential to prevent any narrowing that could lead to complications.
• Step 3: If any narrowing of the graft has occurred, the surgeon may perform a revision of the graft to correct this issue before proceeding with the reconstruction.
• Step 4: The vascularized epithelial tissue is then shaped into a tubular neourethral structure. This is done over a transurethral catheter or stent, which helps maintain the proper shape and patency of the new urethra during the healing process.
• Step 5: The tubular graft is secured in place using midline anastomosis, which involves a running suture technique interspersed with interlocking sutures to ensure a strong and secure closure.
• Step 6: Finally, the wound is closed in layers to promote optimal healing, and the catheter or stent is left in place to facilitate urine drainage during the postoperative period.

3. Post-Procedure

After the completion of the second stage of urethroplasty, patients can expect a recovery period during which careful monitoring is essential. The catheter or stent that was placed during the procedure will remain in situ to allow for proper urine diversion and to prevent any complications during the healing process. Patients may experience some discomfort and will be advised on pain management strategies. Follow-up appointments will be necessary to assess the healing of the neourethra and to ensure that there are no complications such as strictures or infections. The overall recovery time can vary based on individual patient factors and the complexity of the procedure.
