Sonodynamic therapy for intestinal obstruction caused by intestinal metastasis of bladder cancer: A case report

•Developed a novel sonodynamic therapy model for treating intestinal obstruction caused by bladder cancer metastasis.•Demonstrated significant improvement in bowel dilation and obstruction relief through CT and X-ray examinations.•Highlighted the safety, efficacy, and minimal side effects of sonodynamic therapy in clinical application.•Provided insights into the potential of sonodynamic therapy as a minimally invasive and effective anti-tumor treatment for advanced solid organ tumors. This paper presents a case report of a patient with intestinal obstruction caused by intestinal metastasis of bladder cancer treated with sonodynamic therapy. Sonodynamic therapy is a novel anti-tumor therapy that is safe, effi- cacious, and has minimal side effects. After treatment, the patient's intestinal obstruction was effectively relieved.
