Bladder CA refers to bladder cancer, and CA is the acronym for malignant neoplasm of the bladder. Bladder malignancy is a relatively common clinical tumor of the urinary system. The more common clinical symptom is painless meatus hematuria, which usually presents intermittent episodes. If there are these clinical symptoms, it is recommended to go to the hospital for routine urine and urological ultrasound examination for preliminary judgment. If these findings are found to be abnormal, it is recommended that further CT bladder examination can be done. Once the bladder is found to be occupied, cystoscopy should be performed in a timely manner to remove tissue for pathology. Generally, cystoscopy is the gold standard for diagnosing bladder cancer, and only when confirmed by pathology can bladder cancer be truly diagnosed. If the diagnosis of bladder cancer is confirmed, it is recommended to choose surgery in time. The more common surgical procedure is transurethral resection of bladder tumor, which should be combined with bladder infusion chemotherapy after surgery to prevent recurrence of bladder tumor.
