From the reviews: This book will be a very welcome addition to the urology library since it is the first book on the use of botulinum toxin (BoNT) in the genitourinary tract and is written and edited by two leading pioneers in the field, Michael Chancellor and Christopher Smith. (International Painful Bladder Foundation, January, 2012) This first edition book on botulinum toxin (BoNT) is devoted to its medical applications in the genitourinary tract. All information is supported by extensive references. The text is complemented with numerous easy-to-read tables, and very well designed figures and graphics, some in colour and some black and white. This concisely written, practical, hands-on book is an excellent source of information for all involved in BoNT treatment, including students, residents, fellows, physicians and nurses.
