Description

Urodynamics: Hydrodynamics of the Ureter and Renal Pelvis summarizes the present status of urodynamics in progression. The book presents papers on ureteral morphology as a basis for peristaltic activity; the concept of ureteral peristaltic function; and bioengineering aspects of ureteral function. The text also includes papers on factors controlling ureteral peristalsis; the clinical applications in urodynamics; and the theory and techniques of hydrodynamic measurements. Urologists, physiologists, and medical students taking related courses will find the book invaluable.
