Cystourethroplasty with unilateral or bilateral ureteroneocystostomy, as described by CPT® Code 51820, refers to a surgical procedure aimed at reconstructing the bladder and its associated structures. This procedure is particularly relevant for patients who have experienced congenital anomalies, scarring, or deformities resulting from previous surgeries or traumatic injuries. The term 'cystourethroplasty' indicates that the surgery involves plastic reconstruction of the bladder, which may also extend to the vesical neck and urethra. The choice of reconstruction technique is tailored to the specific condition being treated, ensuring that the surgical approach is appropriate for the patient's unique anatomical and pathological circumstances. To access the bladder, a surgical incision is typically made, which can be either a low midline or a transverse suprapubic incision. The approach to the bladder defect varies depending on its location; defects in the posterior bladder are generally approached intraperitoneally, while those in the dome, anterior bladder, vesical neck, and urethra are approached extraperitoneally. During the procedure, the bladder is incised to allow for inspection of the defect, and if necessary, portions of the bladder, bladder neck, or urethra may be excised. The reconstruction process may involve reconfiguring the bladder wall, such as plicating the bladder neck or performing a Y-plasty to address an enlarged bladder trigone. In the context of CPT® Code 51820, the procedure specifically addresses defects located near one or both ureteral orifices, necessitating a ureteroneocystostomy in conjunction with the cystourethroplasty. This involves ligating and transecting one or both ureters at the ureterovesical junction, followed by the repair of the bladder defect and the transplantation of the ureters to a new site within the bladder. The surgical technique includes creating a trough in the muscular wall of the bladder where the ureter(s) will be placed, followed by securing the ureter(s) to the bladder's interior with sutures and closing the trough over the proximal aspect of the ureter(s). This comprehensive approach aims to restore normal bladder function and anatomy, addressing the underlying issues that prompted the need for surgical intervention.

The procedure described by CPT® Code 51820 is indicated for various conditions that necessitate surgical intervention on the bladder and ureters. The following are the explicitly provided indications for performing cystourethroplasty with unilateral or bilateral ureteroneocystostomy:
The procedure for cystourethroplasty with unilateral or bilateral ureteroneocystostomy involves several critical steps, each designed to address the specific defects in the bladder and ureters. The following outlines the procedural steps as described:
Post-procedure care following cystourethroplasty with unilateral or bilateral ureteroneocystostomy typically involves monitoring for complications and ensuring proper recovery. Patients may require a period of hospitalization for observation and management of any immediate postoperative issues. Pain management, hydration, and monitoring of urinary output are essential components of post-operative care. Follow-up appointments will be necessary to assess the healing process and the functionality of the bladder and ureters. Additional imaging or diagnostic tests may be performed to ensure that the reconstruction has been successful and that there are no complications such as leaks or obstructions. Patients should be educated on signs of potential complications, such as fever, increased pain, or changes in urinary habits, and instructed to report these to their healthcare provider promptly.
