Ureterocele reimplantation usually involves a surgical procedure to help reanastomize a diseased ureter or bladder, and is performed under the supervision of a medical professional. When a patient has a ureteral lesion or a bladder lesion that needs to be removed, ureterocystectomy can be performed to remove the lesion and re-anastomose the ureter or bladder. It is commonly used for urological tumors or trauma at a lower site. The procedure begins with a perforation in the lumbar abdomen, followed by full extraperitoneal freeing of the ureter and excision of the lesion, and then the ureter is sutured to the muscular layer of the bladder with an absorbable suture. After the operation, patients should pay attention to prevent cold and warmth, avoid cold and flu, quit smoking and drinking, and take proper nutrition to improve the physical condition to promote healing. If the patient is not feeling well, he should consult the doctor for examination and early treatment.
