Summary
Primary ureteral stump tumors are rare, especially after nephrectomy for benign conditions. This case highlights a rare urothelial carcinoma in a residual ureteral stump, successfully treated with surgery.
Area of Science:
- Urology
- Oncology
Background:
- Primary tumors of the ureteral stump are exceptionally rare.
- Nephrectomy for benign conditions can leave residual ureteral tissue at risk for malignancy.
Observation:
- A 79-year-old male presented with asymptomatic macroscopic hematuria.
- A cystoscopic examination identified a tumor on the left ureteral stump orifice, 52 years post-nephrectomy for tuberculosis.
Findings:
- Imaging (CT/MRI) confirmed a left ureteral stump tumor.
- Histopathology revealed grade 2-3 urothelial carcinoma with muscle invasion (pT2).
- The patient underwent partial cystectomy and ureteral stump excision without adjuvant chemotherapy.
Implications:
- This case adds to the limited literature on ureteral stump tumors.
- Early diagnosis and surgical management are crucial for rare ureteral stump malignancies.
- Further research is needed to understand the long-term outcomes and optimal treatment strategies.
