Insights
Ureteral reconstruction after pelvic and abdominal tumor resection or stricture is feasible in pediatric oncology patients. Surgical repair can preserve renal function and improve outcomes, with no tumor recurrence or renal complications observed in this study.
Area of Science:
- Pediatric Oncology
- Urology
- Surgical Reconstruction
Background:
- Pelvic and abdominal tumors can involve ureteral segments, necessitating resection.
- Ureteral strictures may arise as a consequence of intensive cancer therapy.
- Urinary reconstruction is crucial for preserving renal function in affected pediatric patients.
Purpose of the Study:
- To present the experience with urinary reconstruction in pediatric oncology patients with ureteral involvement due to tumors or strictures.
- To evaluate the efficacy and outcomes of ureteral reconstructive procedures in this patient cohort.
- To assess the impact of reconstruction on renal function and oncologic control.
Main Methods:
- Retrospective review of pediatric oncology patients undergoing ureteral reconstruction for solid abdominal/pelvic tumors.
- Data collection included diagnosis, surgical procedures, renal function parameters, and follow-up status.
- Follow-up assessments involved serum urea nitrogen/creatinine levels and renal scans.
Main Results:
- Thirteen pediatric patients (8 male, 5 female; mean age 10.1 years) were identified.
- Common indications included en bloc tumor resection (n=8) and ureteral strictures (n=3).
- Boari flap, Leadbetter-Politano reimplantation, and psoas hitch were frequent procedures; 2 patients had elevated renal function markers, and no renal complications or tumor recurrences were noted.
Conclusions:
- Ureteral involvement in abdominal and pelvic tumors requires reconstructive surgery for complete tumor resection and improved survival.
- Ureteral reconstruction effectively preserves renal function in pediatric patients with post-therapy strictures.
- Surgical management of ureteral compromise in pediatric oncology is associated with favorable oncologic and renal outcomes.
Purpose:
Removal of solid tumors of the pelvis and abdominal cavity may require resection of an involved ureteral segment. Ureteral stricture can also be a result of intense therapy. We present our experience with urinary reconstruction in this situation.
Methods:
A retrospective review of pediatric oncology patients with solid abdominal/pelvic tumors who underwent a ureteral reconstructive procedure was done. Institutional review board wavier was obtained for the review. Patient data were collected on diagnosis, procedures performed, renal function, and follow-up.
Results:
Thirteen patients were identified: 8 male and 5 female. The mean age at surgery was 10.1 years. The most common reason for surgery was en bloc tumor resection (n = 8) followed by ureteral strictures (n = 3). The Boari flap, Leadbetter-Politano reimplantation, and psoas hitch were the most common procedures preformed. Follow-up studies included measurements of serum urea nitrogen/creatinine levels as well as renal scans to assess functional status; 2 patients had elevated serum urea nitrogen/creatinine levels at follow-up. The mean follow-up time was 18 months; 4 patients died-none was secondary to renal complications. There were no local tumor recurrences.
Conclusions:
Abdominal and pelvic tumors frequently involve the ureter, and their removal should not necessitate acceptance of poor surgical margins. Complete surgical resection of tumor including involved ureteral segments can prolong survival in patients with extensive abdominopelvic cancers. In another group of patients, ureteral strictures arise secondary to therapy and reconstruction may preserve renal function.
