CPT® Code 51595

Cystectomy, complete, with ureteroileal conduit or sigmoid bladder, including intestine anastomosis; with bilateral pelvic lymphadenectomy, including external iliac, hypogastric, and obturator nodes

The procedure described by CPT® Code 51595 refers to a complete cystectomy, which is the surgical removal of the bladder, performed in conjunction with the creation of a urinary diversion. This urinary diversion can be achieved through either a ureteroileal conduit or a sigmoid bladder, which involves the use of intestinal segments to redirect urine from the kidneys to an external stoma. The procedure also includes a bilateral pelvic lymphadenectomy, which involves the removal of lymph nodes located in the pelvic region, specifically targeting the external iliac, hypogastric, and obturator nodes. The approach is intraperitoneal, meaning that the surgery is conducted within the peritoneal cavity, and it requires careful dissection and mobilization of various structures to ensure the successful removal of the bladder and the construction of the urinary diversion. The detailed steps of the procedure involve incisions, dissection of lymphatic tissues, isolation of bowel segments, and the creation of a stoma for urine expulsion, all of which are critical for the patient's postoperative recovery and management.
