Destrucción transuretral de tejido prostático mediante termoterapia de microonda

Transurethral destruction of prostate tissue by microwave therapy is an alternative to transurethral resection of the prostate (TURP) for patients suffering from benign prostatic hyperplasia. The purpose of microwave thermotherapy is the destruction of the prostatic adenoma in the lateral lobes of the prostate, to improve the symptoms and the elimination of urine. This technology involves placing a catheter containing a microwave antenna at the level of the prostate and limiting microwave radiation at this level. Water is circulated in the catheter to cool the urethra. A Foley-type balloon is inflated at the end of the catheter to control the position of the catheter. Fiberoptic sensors monitor the temperature of the rectum and urethra. Electromagnetic waves emit high-energy photons that interact with prostate tissue, producing heat. Microwave thermotherapy produces coagulation necrosis in the lateral lobes of the prostate up to a distance of 17mm from the urethra, preserving the urethral surface, distal sphincter, urethral mucosa, bladder neck, and prostatic periphery. <a id="
