[EN]The invention relates to a medical prosthesis which is intended for surgical implantation in humans, preferably in women with stress urinary incontinence. The inventive device comprises a serum bag which is placed around the urethra, with the ends thereof positioned inside the abdominal cavity. When pressure in the abdomen is increased, for example owing to a fit of coughing, said pressure is applied against the urethra, thereby occluding same and preventing the release of urine. The inventive prosthesis is advantageous in that it operates automatically without the user having to manipulate the device in order to urinate. In addition, the prosthesis only squeezes the urethra for a few seconds, thereby preventing the discomfort that is generated by devices that squeeze the urethra permanently. The inventive prosthesis, which is very simple and reliable, can be implanted within 30 minutes by means of a single incision in the vagina, such that the patient can be discharged from hospital after a few hours.
[ES]La presente invención describe una prótesis médica para su implantación quirúrgica en humanos, preferentemente en mujeres con incontinencia de orina de esfuerzo. El dispositivo está constituido por una bolsa de suero que se coloca rodeando la uretra, con los extremos dentro de la cavidad abdominal. Cuando se incrementa la presión en el abdomen, por ejemplo con un golpe de tos, dicha presión repercute sobre la uretra, ocluyéndola y evitando así que se escape la orina. La ventaja de la prótesis de la invención es que funciona automáticamente, sin que la paciente tenga que manipular el dispositivo para orinar. Además la prótesis solo oprime la uretra unos segundos, evitando las molestias que generan los dispositivos que oprimen la uretra permanentemente. Presenta una gran sencillez y fiabilidad y su implantación es posible con una única incisión en la vagina, en 30 minutos, posibilitando el alta hospitalaria en unas horas.
