[X-ray intravascular surgery in oncologic urology]

Area of Science:

• Urology
• Oncology
• Interventional Radiology

Background:

• Urologic cancers pose significant treatment challenges.
• Traditional therapies have limitations in efficacy and patient outcomes.
• Minimally invasive endovascular techniques offer new therapeutic avenues.

Purpose of the Study:

• To analyze treatment outcomes of intravascular embolization/chemoembolization and regional chemotherapy in urologic tumors.
• To evaluate the efficacy of these techniques in kidney, urinary bladder, and prostate cancers.
• To highlight the role of X-ray endovascular surgical techniques in oncologic urology.

Main Methods:

• Retrospective analysis of 862 patients with kidney, bladder, and prostate tumors.
• Treatment modalities included intravascular embolization, chemoembolization, and regional chemotherapy.
• Comparison of survival rates and symptom control between different treatment approaches.

Main Results:

• For renal cancer, five-year survival rates were 51% (embolization + nephrectomy) and 77% (chemoembolization + surgery).
• In inoperable renal cancer, survival rates were 3% (embolization) and 25% (chemoembolization).
• Regional arterial chemotherapy resolved symptoms in 90% of bladder cancer patients; embolization achieved 80% hemostasis for bladder bleeding.

Conclusions:

• Intravascular embolization and regional chemotherapy are effective in managing urologic cancers.
• These endovascular techniques demonstrate significant improvements in survival and symptom management.
• X-ray endovascular surgical techniques are crucial for treating oncologic urological diseases.
