The last decade has seen a rapid advance in the management options available to the gynaecologist in treating women with pelvic floor dysfunction. Stress incontinence surgery was revolutionised by the development of the TVT and exciting long term data has confirmed this device as a gold standard in the management of SUI. Overactive bladder has seen the launch of a number of new anticholinergic drugs with better side-effect profiles and dosing schedules. We also now have some alternatives to the drugs including Botulinum Toxin A and neuromodulation. We are developing a greater understanding of the role of childbirth and pregnancy in pelvic floor dysfunction. The last three years has seen the launch of intriguing pelvic floor replacement systems and although we are some way off from achieving long term data on these devices, this is no doubt an important step in the evolution of pelvic floor surgery. This book has been written by a number of authors from different parts of South Africa. The field of urogynaecology is still in its infancy and we therefore have many unanswered questions. In this volume, the reader will therefore encounter varying opinions. There is a significant amount of overlap and difference of opinion and we hope this will stimulate the reader to read widely and formulate his or her own opinion. The electronic format of this text has made it possible to offer it to the reader at an affordable price. We trust that this book will contribute to a better understanding and management of South African women with pelvic floor dysfunction. We dedicate it to the women of South Africa.
