These include surgery, lithotripsy, ureteric stent insertion and radiofrequency ablation. Non surgical treatments include steroid injections in the lower back or radiofrequency sensory ablation. Atrial flutter can be treated more definitively with a technique known as catheter ablation. Other treatments include percutaneous ablation and chemoembolization. Definitive care may include catheter ablation. Management options include pharmacological, surgical, catheter ablation, and placement of an implantable cardioverter-defibrillator. Hastened ovarian aging has been observed after endometrial ablation. Vagal maneuvers or a procedure known as catheter ablation may be effective in certain types. Pulsed laser deposition systems work by an ablation process. Ultrasonic coagulation and ablation systems are also available. This technology can achieve precise ablation of diseased tissue. The standard treatment is primary (transurethral) ablation of the valves. He stated he had a cardiac ablation performed and uses medicine to control the problem. Solid samples can also be introduced using laser ablation. The amount of tissue ablation corresponds to the amount of myopia.
