Transurethral resection of bladder tumor

Tumor is a common physical disease in the human body structure. It causes great harm to your body. The possibility of tumor occurs in almost any part of the human body. When a tumor appears, it is usually removed surgically. Transurethral bladder tumor is a common tumor that occurs in the reproductive organs. It causes great harm to people's daily detoxification system. So what exactly is bladder tumor resection today?

Transurethral bladder tumor resection is a surgical procedure for bladder tumors with carcinoma in situ less than 5 mm in diameter, extroverted carcinoma and inverted papillary carcinoma less than 5 cm in diameter, and invasive carcinoma stage B1T2.

Anesthesia and preoperative preparation

1. Anesthesia method

You can choose general anesthesia, epidural block anesthesia, sacral anesthesia or topical anesthesia.

2. Preoperative Preparation

Most patients with benign prostatic hyperplasia are elderly and usually have coronary artery, valvular and hypertensive heart disease, as well as cerebrovascular disease, chronic lung disease, renal insufficiency and diabetes. Proper treatment is required before surgery. Coagulation function should be basically normal.

Indications

The diameter of carcinoma in situ of bladder tumors is less than 5mm, the diameter of extroverted carcinoma and inverted papillary carcinoma is less than 5cm, and the invasive carcinoma is stage B1T2 and low grade.

Contraindications

1. Severe cardiovascular disease.

2. Obvious abnormalities in coagulation function.

3. Non-transitional epithelial tumors, such as adenocarcinoma and squamous cell carcinoma.

4. Acute cystitis.

5. People with spinal deformity who cannot lie flat.

6. Untreated urethral stenosis.

Surgical procedures

The general steps of the surgery:

1. Carcinoma in situ, most cases of electroresection require careful examination. It is best to use a circular biopsy forceps for biopsy to obtain more tissue. The diameter of the carcinoma in situ resection should not exceed 5 cm.

2. For exotropic carcinoma, when using electroresection endoscope to remove bladder tumor, 150 to 200 ml of bladder instillation fluid is used each time. Usually a small electrosurgical coil is used. It is better to use hypotonic fluid for flushing water.

3. For invasive cancer, the electrosurgical resection starts from the edge of the tumor and then moves toward the center, from the surface to the deep layer. If laser is used to remove bladder tumors, it will not cause obturator nerve reflex and is particularly suitable for tumors on the side wall <2cm.

Postoperative complications

Bladder perforation.

Postoperative Care

Routine surgical care and health education.

Precautions

After electrosurgical resection of bladder cancer, especially after resection of invasive cancer, the bladder wall in the resection area is weak, so continuous bladder drainage is required according to the resection range after surgery. Keeping the drainage unobstructed will make the bladder empty and contracted, which will help stop bleeding and heal the wound. Once drainage is poor and the bladder is overfilled, there is a possibility of secondary rupture in the resection area.

Postoperative diet

Eat easily digestible food, drink plenty of water, and ensure urine output.
