Educational Objectives Attendees will be able to learn more about the anatomical relations and why different types of fistula may occur and the strategy of repair. This is important to understand the different approaches and avoid complications. Classification of the vaginal fistulae, how to differentiate between one fistulae and the other, and how to diagnose it will be presented with details. Attendees will be able to see the different techniques of repair including the tips and tricks of both low and high vaginal fistulae repair and the interposing tissues. This will allow attendees to find out different techniques used for different forms of fistulae including robotic surgeries and other reconstructive procedures for the urethra or ureters. Attendees will get oriented with the possible complications that may appear after fistula repair. The different problems and persistent leakage or de novo overactive bladder or ureteric injuries and others will be discussed in details. This will enable the audience to know how to deal with every possible complication. At the end of the course the attendees will have the time to discuss all the aspects of the fistula problems with the speakers and to exchange knowledge with others. 13/06/2012 Vaginal Fistula; Lessons Learned Workshop # 00 / Monday, 15 October 2012 14:00 – 18:00 Time Time Topic Speaker 14.00 14.15 Introduction & Overview Sherif Mourad 14.15 14.30 Epidemiology Of Vesicovaginal Fistula Suzy Elneil 14.30 14.45 Anatomical Aspects & Etiology Hassan Shaker 14.45 15.00 Classification of Vaginal Fistulae Edward Stanford 15.00 15.15 Discussion All 15.30 16.00 Coffee Break 16.40 17.00 Surgery for Low Vaginal Fistulae Dirk De Ridder 17.00 17.20 Surgery for High Vaginal Fistula Suzy Elneil 17.20 17.40 How to Treat Complications of Fistula Repair Sherif Mourad Discussion All Workshop # Vesicovaginal Fistula in the Introduction Disadvantaged, An Overview •Vesicovaginal fistula (VVF) is a subtype of female urogenital fistula (UGF). •VVF is an abnormal fistulous tract extending between the bladder and the vagina.
