Operation Definition

Moving to its normal location, or other suitable location, all or a portion of a body part

Procedure Overview

Reposition procedures move a urinary structure to its normal location or to another suitable position when it has become displaced or malformed. A well-known example is correcting a horseshoe kidney or a kidney that has dropped from its normal position, and pyeloplasty performed to relocate and reshape the ureteropelvic junction so urine can drain properly.

These procedures address problems that are fundamentally about location or orientation rather than tissue damage - a kidney sitting too low, a ureter that takes an abnormal course, or a congenital anomaly discovered in childhood or found incidentally in an adult. Surgeons free the structure from surrounding attachments and fix it in its corrected position, sometimes with permanent sutures or mesh.

Because the underlying tissue is retained and simply relocated, Reposition differs from procedures that remove, replace, or reinforce urinary tissue.

Anatomy & Axis Detail

Kidney Pelvis, Right

The right kidney pelvis is the funnel-shaped collecting chamber where the major calyces converge before urine passes into the ureter, and its position and orientation affect how well urine drains from the kidney. Reposition of this structure is performed most often as part of a pyeloplasty for ureteropelvic junction obstruction, where the dilated pelvis is mobilized and rotated or relocated relative to a crossing lower-pole vessel or an abnormally high ureteral insertion to restore a dependent, freely draining configuration. Because the ureteropelvic junction is a common site of congenital obstruction, this repositioning is frequently performed in conjunction with reduction or revision of the pelvis itself, and coders should distinguish repositioning, which relocates the structure, from the excision or narrowing of redundant pelvic tissue that may accompany the same operative session.

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.

Coding & Documentation

The operative note needs to describe the structure being moved and confirm that the objective was relocation rather than removal or reconstruction with foreign material. This includes procedures for undescended or ectopic kidneys, correction of ureteral malposition, and pyeloplasty when it is performed primarily to reposition the renal pelvis and ureter rather than to excise a stricture.

A common error is coding pyeloplasty as Repair when the surgeon's actual technique involved detaching and relocating the ureteropelvic segment, which fits Reposition more precisely. Coders should also watch for procedures that combine repositioning with excision of a narrowed segment, since both root operations may need to be captured depending on what was documented.

Commonly Confused With

RepairReposition is often confused with Repair, particularly for pyeloplasty, where the distinction hinges on whether the surgeon primarily relocated the structure or simply closed a defect in place.
TransferIt also differs from Transfer procedures used elsewhere in the body, which move tissue while keeping its blood supply intact for a different purpose, and from Release, which frees a structure from surrounding scar tissue without necessarily changing its final position.
