This volume, focusing on the ureter and the diseases which involve it, is an updated second edition. Many journals and textbooks deal with the physiology, pathology, diagnosis, and therapy of derangements of the urinary tract. In most instances, however, the discussion properly centers on the disease process itself and its primary aspects, with only a tan gential description of effects on the ureter. The editor is therefore correct that the ureter itself should be considered a major organ. Though it has been regarded in the recent past as a simple muscular tube, reacting to stretching or filling by contraction, this simplistic view of ureteral phys iology is changing fast. With expanded knowledge of ureteral physiology, a pharmacology is developing which is becoming useful to the clinician in many ways. One of the most interesting aspects of the ureter is its role in inducing the permanent kidney, the metanephros. Relatively slight displacements in the origin of the ureteral bud result in ectopic ureteral orifices and a wide range of congenital anomalies. An ureteral bud which arises medial to the normal position at the genu of the mesonephric duct results in a lateral, and usually incompetent, ureterovesical junction after the duct is taken up to form a portion ofthe trigone. This appears certainly to be the developmental mechanism which results in primary reflux.

For several decades, the diagnosis of diseases affecting the ureter was based on intravenous excretory urography and techniques of direct opacification. However, the diagnostic strategy has been extensively modified by the advent of helical computed tomography and magnetic resonance imaging. This book, the first to focus specifically on ureteral imaging, covers both the new and the traditional techniques. Their use in the variety of scenarios involving ureteral disease is clearly elucidated with the aid of high-quality informative images.

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.

There has been great progress in ureteral surgery in the last twenty years. The predominant indication is still calculous obstruction but reparative and plastic surgery of the ureter for congenital and acquired lesions are among the most interesting advances in modern urology. The essential goal of this surgery is to ensure free flow of the urine from the kidney to the bladder and so to preserve or improve kidney function which is always affected or threatened by any defect in the excretory pathway. The ideal is to re-establish a closed circuit flow from kidney to bladder by repair or substitution of the ureteral conduit so as to avoid as far as possible the dis abilities that result from diversion of the urine to the skin surface or to the intestine. This objective can now be achieved in the treatment of most of the diseases of the ureter when the relevant kidney is sufficiently healthy to merit conserva tion. The techniques used are not necessarily new but the advent of antibiotics has made it possible to avoid or reduce the risks of infection, pyelonephritis, or pyonephrosis that so often complicated such surgery in earlier times. Progress in the investigation of renal function and of the excretory tract has brought a better understanding of the physio-pathology of the urinary apparatus and more accurate judgement of the results of reparative surgery.
