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, Left
The left kidney pelvis collects urine from the calyces of the left kidney before it drains into the proximal ureter, and its spatial relationship to the renal vessels and ureteropelvic junction determines how freely urine flows downstream. Surgeons reposition this structure chiefly during pyeloplasty for ureteropelvic junction obstruction, mobilizing the pelvis away from an aberrant crossing vessel or correcting a high-inserting ureter so that urine exits along a more dependent, unobstructed path. Left-sided procedures may be influenced by the adjacent spleen and colon, which can affect surgical approach and positioning during laparoscopic or robotic repair. As with the corresponding right-sided procedure, documentation should make clear whether the pelvis is simply being relocated and fixed in a new position or whether redundant tissue is also being excised, since those represent different root operations within the same operative episode.
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.
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.
