Hydrodynamic Elimination of Renal Concretions in Transcutaneous Nephrolithotrypsy

Аннотация

We present here the results of an experimental study of the effects of capture and retention of intrarenal stones in transcutaneous nephrolithotrypsy by irrigation fluid flow and discuss a mathematical model explaining this physical phenomenon. Mathematical modeling and experimental studies were used to formulate the specifications for devices providing increases in stone capture and retention force with a simultaneous reduction in the intrarenal pressure created by the irrigation fluid flow.
