Operation Definition

Altering the route of passage of the contents of a tubular body part

Procedure Overview

Bypass procedures in the urinary system reroute the flow of urine around a damaged, obstructed, or diseased segment so it can drain through a new path instead. Common examples include an ileal conduit or continent urinary diversion after bladder removal, a ureteroneocystostomy that reconnects a ureter to the bladder at a new site, or a yeloureteral bypass for a blocked ureteropelvic junction. These operations are performed when a tumor, stricture, chronic obstruction, or a failed bladder makes normal drainage unsafe, since backed-up urine can damage the kidneys or cause repeated infections.

Patients typically encounter these procedures alongside cancer treatment, after trauma, or when a congenital narrowing has caused progressive kidney damage. The new pathway may be temporary, to protect a healing repair, or permanent, when the original structure cannot be salvaged.

Anatomy & Axis Detail

Ureter, Right

The right ureter is the muscular tube carrying urine from the kidney pelvis to the bladder, and bypass becomes necessary when a segment is irreparably obstructed or destroyed by stricture, tumor invasion, or extensive fibrosis from prior surgery or radiation, such that the natural channel can no longer be restored by simple repair. The procedure creates an alternate route for urine, which may involve connecting healthy ureter above the defect to the bladder, bowel segment, or skin, bypassing the diseased length rather than excising it. On the right, the ureter's course near the appendix, cecum, and iliac vessels can influence which alternate pathway is feasible. Because the ureter is a tubular structure, coding depends heavily on identifying the specific conduit used to reroute flow around the obstruction.

Approach: Open

Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.

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.

Qualifier: Cutaneous

This qualifier indicates that a bypass or fistula procedure terminates at the skin surface rather than at another internal structure, such as when bowel contents are diverted externally. It contrasts with the internal destination qualifiers, like Stomach or Jejunum, which route the bypass to another digestive organ instead.

Coding & Documentation

Coders assign Bypass when documentation confirms a new route was created "from" one urinary structure "to" another (or to the skin, as in a conduit), rather than a repair of the existing channel. The operative note must name both the bypass origin and the qualifier destination, since the seventh-character qualifier changes with the target (bladder, ileum, cutaneous, etc.). A frequent error is coding Bypass when the surgeon actually performed Repair or Dilation of an existing passage rather than constructing an alternate route; another is missing the correct device value when a stent or conduit segment is left in place.

Commonly Confused With

DilationBypass is easily confused with Dilation, which merely widens an existing narrowed segment rather than creating a new route, and with Drainage, which removes fluid without altering the pathway.
TransferIt is also distinct from Transfer/Replacement procedures using bowel segments for reconstruction rather than diversion; the distinguishing question is always whether contents now travel through a route that did not exist before.
