Progress in urodynamic research on the upper urinary tract: implications for practical urology.
The development of new surgical techniques for bladder substitution and continent urinary diversion has extended interest in urodynamics of the upper urinary tract. From a subdiscipline attracting mainly scientists and bioengineers, renal pelvic kinetics and ureteral peristalsis have evolved as important factors in routine clinical urology. The observed changes in peristaltic pattern during high diuresis, obstruction and urinary reflux have influenced management of stone disease and neurogenic bladder. The demonstration that high intravesical pressure is reflected to the kidney not only when the ureteric orifice is incompetent, but also during high diuresis, established the necessity for low pressures in neobladders. Much further clarification of urinary transport from the renal tubules to the bladder should be achievable by refined techniques of fluoroscopy, isotopic renography and manometry.
