| Abstract: |
The purpose of urodynamic testing is to measure and record various physiological variables while the patient is experiencing those symptoms which make up the presenting complaint. This chapter on benign prostatic hyperplasia (BPH), bladder neck obstruction, and prostatitis is from an atlas of urodynamics that provides a comprehensive, detailed look at the indications, technology, and use of urodynamics in modern urologic practice. The chapter begins with a section defining the terminology currently in use, then goes on to cover mechanical obstruction, smooth muscle obstruction, differential diagnosis, urodynamic evaluation, primary bladder neck obstruction, acquired voiding dysfunction, bladder diverticula, the neurogenic bladder and BPH, and chronic pelvic pain syndrome and prostatitis. The authors then present case illustrations, accompanied by figures and black-and-white photographs of actual urodynamic tests. The authors note that, even in patients with documented prostatic obstruction, factors other than the mechanical effects of prostatic bulk play an important role. These include detrusor muscle strength and tone, bladder wall compliance, smooth muscle function of the bladder neck and prostatic urethra, striated muscle function of the prostate-membranous urethra, and interstitial factors such as elastin and collagen type. 18 figures. 1 table. 15 references. |
