[ADULT / INJURY / STRICTURE:]
The patient is a [age]-year-old [male / female] with right [left] distal ureteral [stricture / injury] secondary to [pelvic surgery / radiation / ureteral cancer excision]. The ureteral defect is [X] cm in length. Direct repair was not feasible given [defect length / distal ureteral quality]. Ureteral reimplantation [with psoas hitch] planned.
[PEDIATRIC VUR:]
The patient is a [age]-year-old [male / female] with [right / left / bilateral] vesicoureteral reflux, Grade [III / IV / V], confirmed on voiding cystourethrogram. [Breakthrough febrile UTI on continuous antibiotic prophylaxis (CAP). / Renal cortical scarring on DMSA scan. / Grade V VUR — surgical threshold per AUA guideline.] [Failure of antibiotic prophylaxis after adequate trial.] Risks including ureteral obstruction, persistent reflux, need for reoperation, and anesthetic risks discussed. Consent obtained.
The right [left] ureter was identified and traced to the level of the injury/stricture at [X] cm from the bladder. The ureteral defect was [X] cm. The proximal ureteral end was healthy with adequate caliber and visible peristalsis. The bladder [was mobile and could reach the ureter with psoas hitch / required Boari flap given [X]-cm defect that exceeded psoas hitch reach]. Anti-reflux tunnel of [X] cm constructed (5:1 tunnel-to-ureter diameter ratio per Paquin's rule).
The patient was positioned supine. A [midline / Pfannenstiel] incision was made. The retroperitoneum was entered. The right [left] ureter was identified at the pelvic brim and dissected distally to the site of injury/stricture, preserving the periureteral tissue to protect the ureteral blood supply.
The ureter was transected [X] cm above the normal-appearing proximal ureteral tissue. The proximal ureteral end was spatulated [1 cm] on its medial/anterior surface. Ureteral caliber and patency confirmed with a [5 Fr] feeding tube.
[PSOAS HITCH:]
The bladder was mobilized by dividing the contralateral superior vesical pedicle. The bladder was brought toward the ureter. [The psoas minor tendon was identified — present / absent.] The bladder was secured to [the psoas minor tendon (when present) / the psoas major muscle — longitudinal sutures parallel to the muscle fibers, avoiding deep or lateral bites to protect the genitofemoral nerve on the anterior surface of the psoas and the femoral nerve within the psoas muscle] with [2] non-absorbable [2-0 Prolene] sutures, bringing the bladder [4-6] cm toward the ureter.
[LICH-GREGOIR EXTRAVESICAL TECHNIQUE:]
The bladder was not opened. The detrusor muscle was incised longitudinally for [3-4] cm on the posterolateral bladder wall to create a detrusor trough, leaving the bladder mucosa intact (mucosa not entered / a small mucosal opening was made at the distal end only). The ureter was laid in the trough. The detrusor was closed over the ureter with [2-0 Vicryl], creating a submucosal tunnel of [X] cm (5:1 ratio to ureteral diameter of [X] mm — anti-reflux mechanism). The ureterovesical anastomosis was completed at the distal end.
[COHEN CROSS-TRIGONAL INTRAVESICAL TECHNIQUE (pediatric VUR):]
A [3-4]-cm cystotomy was made. The intravesical ureter was dissected free of the trigone for [X] cm. A submucosal tunnel was created across the trigone toward the contralateral side. The ureter was pulled through the tunnel submucosally, with tunnel length [X] cm (5:1 tunnel-to-ureter diameter ratio per Paquin's rule). The ureterovesical anastomosis was constructed with [5-0 Vicryl] interrupted sutures.
[POLITANO-LEADBETTER INTRAVESICAL TECHNIQUE:]
Cystotomy made. A new hiatus was created superolateral to the original orifice. The ureter was rerouted through the new hiatus and a submucosal tunnel of [X] cm was created (5:1 ratio). Anastomosis completed with [5-0 Vicryl].
A [6 Fr × 22-26 cm] DJ stent was placed [antegrade / retrograde]. [For pediatric patients: [4.7 Fr × 12-16 cm] DJ stent.]
[Cystotomy closed with 3-0 Vicryl.] A [16 Fr] urethral catheter and [19 Fr] pelvic drain were placed. The wound was closed in layers.

The patient was taken to the PACU in stable condition. Drain removed when output less than 50 mL/day with drain creatinine confirming non-urinary fluid. Urethral catheter removed at [5-7 days]. DJ stent removed cystoscopically at [6 weeks].

Boari flap for long ureteral defects
For defects of 10-15 cm that cannot be bridged by psoas hitch alone. A bladder flap is outlined anteriorly based on a posterior pedicle with superior vesical artery supply. Critical: flap length-to-width ratio must not exceed 3:1 to prevent ischemic necrosis of the flap tip. The flap is tubularized over a stent with running [3-0 Vicryl] to form a neo-ureter. The proximal end is anastomosed end-to-end to the native ureter with [5-0 Vicryl]. Boari flaps can bridge defects up to 15 cm; for defects >15 cm, consider ileal ureter interposition or renal autotransplantation.
Robotic/laparoscopic ureteroneocystostomy
Both codes apply regardless of patient age or robotic vs. standard laparoscopic approach. Document port configuration, extravesical vs. intravesical technique, anti-reflux tunnel length, and stent placement.
Pediatric VUR — Cohen cross-trigonal (intravesical, open)
Most common open pediatric intravesical technique for bilateral VUR. Both ureters can be reimplanted through a single cystotomy by crossing each ureter across the trigone to the contralateral side. Published success rates approximately 98%. Ideal for bilateral VUR or when extravesical approach risks ureteral devascularization. Limitations: requires intravesical dissection (post-op hematuria, spasm), and retrograde catheterization may be difficult post-op (crossed ureters). Document bilateral tunnel length and 5:1 ratio on each side.
Megaureter tapering
For primary obstructive or refluxing megaureter where the dilated ureter is too large for an effective anti-reflux tunnel (typically >1 cm diameter). Two techniques: excisional tailoring (Hendren) — longitudinal strip of ureter excised and closed over a stent; or imbrication/plication (Starr) — excess wall folded inward and plicated. Taper to approximately 10-12 Fr for adequate 5:1 tunnel ratio. Document pre-taper ureteral diameter, technique used, and post-taper caliber.
Charting Tips
- Document anti-reflux tunnel length and ratio. Paquin's 5:1 rule (tunnel length to ureteral diameter) is the established teaching standard. Measure tunnel length and ureteral diameter; document: 'submucosal tunnel of [X] cm created; ureteral diameter [X] mm; 5:1 tunnel-to-ureter ratio achieved.' Recent evidence suggests 3-4:1 may be adequate but 5:1 remains the board and teaching standard.
- Document psoas hitch suture placement with nerve anatomy note. The psoas minor tendon is absent unilaterally in approximately 65% of patients. Document: 'psoas minor tendon [present and used / absent]; sutures placed [in psoas minor tendon / longitudinally through psoas major muscle parallel to fibers, avoiding deep/lateral bites to protect the genitofemoral nerve on the anterior surface and femoral nerve within the psoas].'
- Document preservation of periureteral tissue and ureteral blood supply. The ureter derives its blood supply from segmental branches running in the periureteral adventitia — stripping this tissue causes ischemia and stricture. Document: 'ureter dissected with periureteral tissue preserved to maintain blood supply.'
- Document drain creatinine before removal. Elevated drain creatinine (>2x serum creatinine) indicates anastomotic leak/urinoma. Document: 'drain output [X] mL, creatinine [X] — consistent with serosanguinous (non-urinary) fluid; drain removed.'
- For pediatric VUR: document VUR grade (per VCUG), laterality, prior CAP trial and duration, breakthrough febrile UTI history, and DMSA findings (renal scarring). These establish surgical indication for insurers and are required for medical necessity documentation.
Documentation & Reimbursement Considerations
- Report Ureteral Reimplantation (Ureteroneocystostomy) as the primary service when it is the definitive operation performed.
- Bilateral reimplantation at the same session: bill each side separately with right-side reporting and left-side reporting on two separate claim lines. The higher-valued side is paid at 100%; the lower-valued side is subject to the multiple-procedure reduction (typically 50% by Medicare). Do not mix bilateral-procedure reporting with right- or left-side reporting billing; choose one convention per payer requirements.
- Ureteral stent placement (the applicable service, 2.75 wRVU) is NCCI-bundled with the open ureteroneocystostomy codes (the primary and related services) when performed at the same session through the same approach.
- Global period is 90 days. Post-op stent removal at cystoscopy, urogram, and routine follow-up are bundled. The stent removal cystoscopy after 90 days is separately billable.
