RESUMEN

INTRODUCTION: We have implanted the FlowSecure artificial sphincter for the first time in October 2006. The prototype was originally conceived and designed by Professor Craggs M. D. and Professor Mundy A.R. Preliminary clinical results were reported in nine patients early this year. Our objective is to spread technique for surgical implantation. METHODS: Combined perineal and abdominal incisions are required for exposure of bulbar urethra, creation of a cavity in the para-vesical space and dissection of a pocket under de scrotal wall. A trocar with a stylet is routed from the abdominal incision to the perineal incision to pass the deflated cuff to the perineal site. The cuff is placed around the urethra and secured with Prolene sutures. After refilling the cuff, fluid is removed from the system until the stress relief balloon becomes just indented (atmospheric pressure 0). The pump is placed in the scrotum and the balloons in the paravesical space. RESULTS: We have implanted our first FlowSecure artificial sphincter in a patient with severe stress incontinence following a T.U.R.P. The surgical technique is simple and associated with little handling. He was discharged from hospital 4 days after the procedure and it was decided that pressurisation was unnecessary. DISCUSSION: Surgical implantation of the new FlowSecure artificial urinary sphincter is an easy procedure in males with stress urinary incontinence. Knigth et al. reported 30 to 40 minutes operating time, 4 days mean hospital stay and unnecessary pressurisation procedure in 3 out of their 9 patients. It seems that their results are reproducible.

RESUMEN

Introducción: En Octubre de 2006 se implantó por primera vez en nuestra Institución el nuevo esfínter urinario artificial FlowSecure TM. El prototipo fue concebido y diseñado por los Profesores Craggs MD y Mundy AR y los resultados clínicos preliminares de 9 pacientes fueron publicados a mediados del 2006. Nuestro objetivo es el de difundir la descripción detallada de la técnica quirúrgica para la implantación de esta nueva prótesis. Materiales y métodos: Se requiere una incisión perineal para la exposición de la uretra bulbar y una abdominal para la creación de un espacio paravesical y de un bolsillo escrotal. Se coloca un trocar con un estilete desde la incisión abdominal a la perineal para pasar el manguito desinflado, que se ajusta a la uretra y se asegura con tres puntos de Prolene. Tras volver a llenar el manguito se extrae líquido hasta que se forma una muesca en el reservorio de asistencia al estrés, indicando que el sistema está a presión atmosférica 0. Se coloca entonces la bomba en el escroto y los reservorios en el espacio paravesical. Resultados: El esfínter fue colocado en un paciente con incontinencia de esfuerzo tras una RTU de próstata. La técnica es simple, el paciente se fue de alta al cuarto día y no fue necesario presurizar el sistema porque el paciente recuperó la continencia desde la retirada de la sonda. Discusión: La implantación en uretra bulbar es muy sencilla. Los resultados en este paciente concuerdan con los de Knigth et al., que describen tiempo quirúrgico de 30 a 40 minutos, media de estancia hospitalaria de 4 días y presurización innecesaria en tres de sus nueve pacientes. Parece que la técnica y los resultados son reproducibles
