Abstract:
The authors report five cases of fibrous polyps of the urinary tract, which is a rare disease, as Mazeman only reported 12 cases in his review in 1972. These cases confirm the polymorphic nature of the clinical presentation and the site of these tumours of mesodermal origin, essentially composed of richly vascular connective tissue covered with surface epithelium. Treatment is surgical and conservative. The authors performed two junctional resections, one ureterotomy, one ureteroscopic resection and one nephro-ureterectomy for a partially destroyed kidney.
Insights
This study details five rare cases of urinary tract fibrous polyps, confirming their varied clinical presentations and mesodermal origin. Surgical intervention is the recommended conservative treatment for these vascular connective tissue tumors.
Area of Science:
- Urology
- Pathology
- Surgical Oncology
Background:
- Fibrous polyps of the urinary tract are rare mesodermal tumors.
- Previous literature, such as Mazeman's 1972 review, reported limited cases (12).
- Understanding the diverse clinical and pathological features is crucial for diagnosis and management.
Observation:
- Five distinct cases of urinary tract fibrous polyps were analyzed.
- These tumors exhibited a polymorphic clinical presentation.
- Tumor sites varied, highlighting the disease's unpredictable nature.
Findings:
- The polyps are of mesodermal origin.
- Histologically, they consist of richly vascular connective tissue.
- The surface is covered with epithelium.
Implications:
- Surgical treatment is the primary therapeutic approach.
- Conservative surgical techniques, including junctional resections and ureterotomy, are feasible.
- Radical nephro-ureterectomy may be necessary for severely damaged kidneys.
