Operation Definition
Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part
Procedure Overview
Replacement procedures put in biological or synthetic material that physically takes over for all or part of a urinary structure that has been removed or has failed. The clearest example is placement of an artificial urinary sphincter to manage stress incontinence, or use of a segment of bowel or synthetic material to reconstruct the bladder after part of it has been taken out.
These procedures are chosen when native tissue can no longer perform its job and a substitute - whether a manufactured device or tissue moved from elsewhere in the body - is put in its place. Candidates include patients recovering from bladder cancer surgery, those with severe incontinence unresponsive to other treatments, or people whose urethra has been damaged beyond simple repair.
Because the replaced material functions in place of the original structure going forward, these procedures are usually more involved and longer-lasting in their effect than repair or reposition.
Anatomy & Axis Detail
Ureter, Left
Replacement of the left ureter involves excising a compromised segment, often due to extensive stricture, tumor involvement, radiation damage, or a failed previous reconstruction, and substituting it with other tissue, most frequently a segment of ileum fashioned into a conduit that bridges the gap between the renal pelvis and the bladder or a lower ureteral stump. This is distinct from simple repair, which restores the ureter's own tissue, since replacement introduces nonureteral material to reestablish the urinary pathway. Surgeons must carefully orient and anastomose the replacement segment to preserve peristaltic-like drainage and reduce the risk of reflux or stricture at the anastomotic sites. A stent commonly protects the reconstruction while it heals. Coders should confirm that a ureteral segment was actually excised and substituted, not merely repaired, dilated, or bypassed.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Device: Synthetic Substitute
Synthetic Substitute designates a device made from manufactured, non-biologic material, such as mesh or prosthetic components, used to replace or augment a body part. It is distinguished from the two tissue substitute categories by its artificial composition, which carries different considerations for integration and long-term durability than biologic grafts.
Coding & Documentation
Documentation must show that material - whether a device, donor tissue, or the patient's own tissue harvested from elsewhere - was put in to functionally substitute for the body part, not just reinforce or patch it. The note should identify the material used and confirm that any diseased or damaged native tissue was removed first, since Replacement often follows a Resection or Excision performed in the same operative session.
A common coding mistake is applying Replacement when the correct root operation is actually Supplement, which reinforces existing tissue without taking over its function entirely. Coders also sometimes overlook that bladder augmentation using a bowel segment qualifies as Replacement because it uses tissue to take over bladder function, and instead code it only as the harvesting procedure.
