Summary
This study highlights a case of ureteral fibroepithelial polyp causing obstruction. Ureteroscopy proved effective for diagnosis and treatment, with transurethral resection recommended.
Area of Science:
- Urology
- Pathology
Background:
- A 46-year-old male presented with hematuria and flank pain, exhibiting renal dysfunction and bilateral hydronephrosis.
- Diagnostic imaging revealed left ureteral calculi and a right ureteral filling defect.
Observation:
- Bilateral ureteral stenting improved renal function.
- Ureteroscopy identified a smooth-surfaced right ureteral tumor, biopsied as a fibroepithelial polyp without malignancy.
- Left ureteral calculi were treated with transurethral lithotripsy.
Findings:
- Histopathological diagnosis confirmed a benign fibroepithelial polyp of the ureter.
- Conservative management with serial urine cytology and retrograde pyelography showed no recurrence or malignancy.
- Ureteroscopy is valuable for diagnosing ureteral polyps.
Implications:
- Ureteroscopic transurethral resection is a recommended treatment for ureteral polyps.
- This case underscores the importance of ureteroscopy in evaluating ureteral masses.
- Benign fibroepithelial polyps can cause significant urinary tract obstruction.
