Functional urology is that part of urological practice which deals with functional disorders of the lower urinary tract. Presenting patients may be male or female, and their complaints may be of neurogenic or non-neurogenic origin. Among the diseases that cause functional disorders are spina bifida, spinal cord injury, pelvic organ prolapse, and urethral strictures. This book on practical functional urology will help urologists, urogynecologists, and others to diagnose and treat these functional disorders. The theoretical background and scientific basis are summarized, but the emphasis is very much on clinical practice. Diagnosis and treatment are presented for a variety of conditions, including overactive bladder, detrusor underactivity, painful bladder syndrome/interstitial cystitis, prostatitis, stress urinary incontinence, pelvic organ prolapse, urinary tract infections, and urethral disorders. The content is based on the EAU guidelines, and for each disorder, helpful tips and tricks are highlighted.
