Summary
Bladder tumors, often originating from the vesical mucosa, present with hematuria. Diagnosis relies on cystoscopy, while treatment varies from resection for benign cases to surgery and radiotherapy for malignant tumors.
Area of Science:
- Urology
- Oncology
Context:
- Bladder tumors arise from the vesical mucosa in most cases.
- Hematuria is a common initial symptom, observed in 75% of patients.
- Routine diagnostic tools include intravenous urography and Papanicolaou-stained urinary cytology.
Purpose:
- To detail the diagnostic approaches for bladder tumors.
- To outline treatment strategies based on tumor characteristics and staging.
- To emphasize the role of cystoscopy and pathological examination in treatment planning.
Summary:
- Cystoscopy provides a precise assessment of bladder lesions.
- Pathological examination of resected tumors reveals malignancy grade, depth of invasion, and differentiation.
- Tumor factors like site, size, and lymph node status influence treatment decisions.
Impact:
- Benign or borderline tumors infiltrating the muscularis mucosae are managed with resection or coagulation.
- Malignant tumors necessitate combined cobalt therapy and surgery.
- Surgical interventions range from partial cystectomy for mobile tumors to total cystectomy for trigonal tumors, with various urinary diversion techniques.
- Radiotherapy is reserved for patients with poor general health and highly dedifferentiated tumors.
