BACKGROUND Botulinum neurotoxin (BoNT) is probably the most potent biological toxin that can affect humans. Since its discovery by Justinus Kerner, BoNT has seen use in a wide range of cosmetic and non-cosmetic conditions such as cervical dystonia, cerebral palsy, migraines and hyperhidrosis. We tried to trace its history from its inception to its recent urological applications. METHODS Historical articles about botulinum toxin were reviewed and a Medline search was performed for its urological utility. We hereby present a brief review of historical aspects of BoNT and its applications in urology. RESULTS In 1793, the first known outbreak of botulism occurred due to 'spoiled' sausage in Wildebad, Germany. The German physician and poet Justinus Kerner published the first accurate description of the clinical symptoms of botulism (sausage poison). He was also the first to mention its potential therapeutic applications. In urology, BoNT has been used in bladder and urethral lesions with varying degree of success. Recently, BoNT applications were explained for prostatic disorders. BoNT applications in urology are in the treatment of detrusor external sphincter dyssynergia, detrusor overactivity, detrusor underactivity, spastic conditions of the urethral sphincter, chronic prostate pain, interstitial cystitis, non-fibrotic bladder outflow obstruction (including benign prostatic hyperplasia) and acute urinary retention in women. CONCLUSIONS Justinus Kerner is the godfather of botulism research. The role of BoNT in urology has evolved exponentially and it is widely used as an adjuvant in voiding dysfunction. In the future, its utility will broaden and guide the urologist in managing various urological disorders.

D001743 Urinary Bladder A musculomembranous sac along the URINARY TRACT. URINE flows from the KIDNEYS into the bladder via the ureters (URETER), and is held there until URINATION.

D001905 Botulinum Toxins Toxic proteins produced from the species CLOSTRIDIUM BOTULINUM. The toxins are synthesized as a single peptide chain which is processed into a mature protein consisting of a heavy chain and light chain joined via a disulfide bond. The botulinum toxin light chain is a zinc-dependent protease which is released from the heavy chain upon ENDOCYTOSIS into PRESYNAPTIC NERVE ENDINGS. Once inside the cell the botulinum toxin light chain cleaves specific SNARE proteins which are essential for secretion of ACETYLCHOLINE by SYNAPTIC VESICLES. This inhibition of acetylcholine release results in muscular PARALYSIS.

D001906 Botulism A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION. Clinical features include abdominal pain, vomiting, acute PARALYSIS (including respiratory paralysis), blurred vision, and DIPLOPIA. Botulism may be classified into several subtypes (e.g., food-borne, infant, wound, and others).
