Clinical Scorecard: Robotic Surgical Reconstruction of Ureteral Strictures Resulting from Endometriosis: Findings from a Multi-Center Study
At a Glance
Category
Detail
Condition
Ureteral strictures caused by endometriosis
Key Mechanisms
Extrinsic compression and fibrosis from endometriotic tissue causing ureteral obstruction
Target Population
Women with ureteral strictures secondary to endometriosis, including those with or without prior endometriosis diagnosis or treatment
Care Setting
Multi-institutional surgical centers utilizing robotic surgical systems
Key Highlights
Ureteral involvement in endometriosis occurs in approximately 1% of affected women and can cause significant obstruction.
Robotic ureteral reconstruction (RUR) techniques demonstrated a 94.7% surgical success rate at median 22.5 months follow-up.
Various RUR techniques including refluxing ureteral reimplantation, side-to-side reimplantation, ureteroureterostomy, and buccal mucosa graft onlay ureteroplasty were utilized based on stricture location and severity.
Guideline-Based Recommendations
Diagnosis
Use cross-sectional imaging to identify ureteral strictures and assess hydronephrosis.
Evaluate renal function with nuclear medicine renal scans including furosemide administration to assess drainage.
Confirm diagnosis with surgical pathology demonstrating endometrial tissue in periureteral specimens.
Management
Consider robotic ureteral reconstruction for complex or densely adherent endometriosis-induced ureteral strictures not amenable to ureterolysis alone.
Select surgical technique based on stricture location: refluxing ureteral reimplantation for distal strictures, ureteroureterostomy for proximal strictures with preserved distal ureter, and non-transecting approaches for redo cases or minimal periureteral damage.
Place double J ureteral stent intraoperatively and remove between 4 to 6 weeks postoperatively.
Monitoring & Follow-up
Perform serial postoperative evaluations at 3, 6, and 12 months including imaging with renal ultrasound or diuretic renogram after stent removal.
Use additional cross-sectional imaging or repeat renogram between 6 and 12 months to assess anatomic and functional outcomes.
Define surgical success as absence of need for further surgical intervention or indwelling hardware.
Risks
Potential for postoperative complications such as intra-abdominal abscess requiring drainage.
Risk of symptomatic stricture recurrence requiring chronic stenting.
Patient & Prescribing Data
Women undergoing robotic ureteral reconstruction for endometriosis-induced ureteral strictures
RUR provides durable surgical success with low complication rates and is effective even in patients with prior failed interventions or without prior medical therapy for endometriosis.
Clinical Best Practices
Tailor surgical approach to stricture location and extent of periureteral endometriotic involvement.
Utilize intraoperative indocyanine green fluorescence to assess ureteral perfusion and anatomy when needed.
Reserve ureteroscopy for cases with difficult ureteral identification.
Ensure multidisciplinary collaboration and follow standardized postoperative imaging protocols for optimal outcomes.
