CPT® Code 51045

The procedure described by CPT® Code 51045 refers to a cystotomy, which is a surgical operation involving an incision into the urinary bladder. This procedure is performed to facilitate the insertion of a ureteral catheter or stent, and it is classified as a separate procedure. During a cystotomy, the surgeon exposes the urinary bladder and makes a small incision in its wall. This access allows for the introduction of a guidewire, which is carefully advanced through the incision and into the ureter, ultimately reaching the renal pelvis. Following the guidewire's placement, a catheter can be advanced over it to the renal pelvis, allowing for drainage or other therapeutic interventions. The guidewire is then removed, and the ureter may be irrigated with normal saline or other solutions for diagnostic or therapeutic purposes. Alternatively, a ureteral stent can be placed over the guidewire, which is then positioned to ensure proper placement within the renal pelvis and urinary bladder. This procedure is essential for managing various urological conditions and ensuring proper urinary drainage.
