Introduction: SAFYRE TM is a readjustable and minimally invasive sling for the treatment of stress urinary incontinence (SUI). It is as a pubovaginal sling placed in the medial third of the urethra. The initial experience is described. Materials and Methods: Forty-five patients (mean age = 59 years) underwent a SAFYRE TM implant to treat SUI. Physical examination and urodynamic study were performed before surgery. All patients presented symptoms of SUI and 20% also reported mild urgency. Approximately 60% of this group had a previously failed anti-incontinence procedure. Urethral hypermobility was diagnosed in 40% of the patients and intrinsic sphincter deficiency (ISD) in 60% of the cases. Results: The average follow up period was 10 months. The mean operative time was 20 minutes. Dystopia repair was performed whenever necessary, during the same procedure. The average hospital stay was 24 hours. In 11% of the implants, bladder perforation occurred. During the postoperative period, 9 patients (20%) developed transient urgency symptoms. During the initial follow up period, 90% were found to be continent, 3% reported an improvement and 7% were unchanged. Conclusion: SAFYRE TM is a safe and quick procedure that allows postoperative readjustment. This technique may be an attractive alternative in the management of SUI, should the good result obtained so far prove to be long lasting.

Los procedimientos tipo sling han sido utilizados por decadas para el manejo de la incontinencia urinaria de esfuerzo (IUE) femenina, pero solo en la decada pasada han llegado a ser la tecnica de eleccion. Los procedimientos minimamente invasivos son el procedimiento de eleccion en algunos centros por su eficacia y baja morbilidad. El soporte uretral tendinoso (TUS) representa un enfoque anatomico que consiste en colocar una cincha de baja tension a nivel de la uretra media, anclada al arco tendineo de manera bilateral. De febrero 1999 a octubre 2000, 25 pacientes femeninas con IUE y con una edad media de 53 anos fueron intervenidas mediante TUS. De ellas, 23 pudieron evaluarse a largo plazo con un seguimiento un maximo 72 meses. Despues de 6 meses, 20 pacientes (87%) se encontraban secas, 2 (8,7%) mejoraron y 1 (4,3%) era incontinente. Sin embargo, al final del seguimiento, 15 pacientes estaban continentes (65,2%), 3 (13%) mejoraron y 5 (21%) seguian incontinentes. Por lo que, el TUS es un concepto que merece investigaciones adicionales.

INTRODUCTION Stress Urinary Incontinence (SUI) may be managed by transobturator approach. We developed a three-dimensional model, for understanding the surgical anatomy and manual training as well, in order to reduce the learning curve for pelvic surgeries. OBJECTIVE To demonstrate in synthetic models, the anatomical basis for the management of SUI and cystocele. METHOD The anatomical model includes: pelvic bones, the main layers of the pelvic muscles, ligaments and fascias. The surgical devices were transobturator needles, synthetic slings and meshes for anterior vaginal wall repair. The workshop was carried out with an anatomical overview and hands-on training in this tridimentional models and finally surgery in animals. At the end, a questionnaire was applied to verify the impact of this tool in the learning process and trainee satisfaction. RESULTS As far as the anatomical concept, 90% (n=72) of the participants classified this model as very good and 10% (n=8) as good. As a tool for understanding the tridimentional pelvic floor anatomy applied to transobturator procedures there were 100% of approval. CONCLUSIONS This synthetic model allows for understanding the pelvic floor tridimentional anatomy and surgical procedures as well. Further skill is got in the animal model reducing the learning curve for transobturator procedures.Resumen Introduccion La Incontinencia Urinaria de Esfuerzo (IUE) se maneja quirurgicamente diferente siguiendo la Teoria Integral de la Continencia razon por la cual es importante el conocimiento de las estructuras anatomicas. Desarrollamos un modelo tridimensional basado en la anatomia de la pelvis para el entrenamiento manual de la cirugia y asi disminuir la curva de aprendizaje de urologos y ginecologos Objetivo Demostrar en modelos sinteticos, las bases anatomicas del manejo transobturatriz en la IUE, cistoceles y en IUE recidivante post tratamiento quirurgico Metodologia El modelo anatomico incluye: huesos pelvicos, las principales capas de los musculos pelvicos, ligamentos y fascias. Los dispositivos quirurgicos son agujas transobturatrizes en forma de “C” y helicoidales; un sling reajustable de acceso universal y una malla especial autofijable y el sling crossover. Fue realizado un entrenamiento con clases teoricas y practicas. Las clases practicas fueron realizadas con las pelvis y los dispositivos de la cirugia transobturatriz. A continuacion fueran realizadas cirugias transobturatrizes en ovejas. Al final, se aplico un cuestionario para verificar el impacto de esta herramienta en la curva de aprendizaje del acceso transobturatriz Resultados Con respecto al concepto anatomico, el 90% (n=72) de los participantes, clasifico el modelo como muy bueno y 10% (n=8) como bueno. Como herramienta para el aprendizaje de los procedimientos transobturatrizes, el 100% aprobo tanto el material escrito como el modelo anatomico tridimensional Conclusiones Este modelo sintetico permite entendery poner en practica las diversas tecnicas quirurgicas,substituyendo los modelos animales, las reconstrucciones tridimensionales computarizadas y las imagenes bidimensionales, contribuyendo asi de forma significativa en la curva de aprendizaje
