The minimally invasive use of botulinum toxins (BoNT) in the lower urinary tract has transformed the treatment of difficult bladder, urethra, and prostate conditions refractory to conventional therapy. This is the first book on the practical application of BoNT to the genitourinary tract. An introductory section focuses on the anatomy, physiology, and pathophysiology of the genitourinary tract and the biology and pharmacology of BoNT. Applications of BoNT in the bladder and the prostate and pelvic floor are then discussed in detail, with reviews of the latest clinical series and techniques of BoNT injection. The book closes by considering non-genitourinary uses of BoNT and issues of health economics.
