The use of an abdominal compression belt to reduce stone movement during extracorporeal shock wave lithotripsy.
We used an abdominal compression belt in 50 patients undergoing extracorporeal shock wave lithotripsy with the Siemens Lithostar lithotriptor to limit diaphragmatic excursion and, therefore, renal calculus movement. Stone movement was measured on the monitor with and without the compression belt. Abdominal compression was found to decrease the range of stone movement by an average of 32% (-4 to 63%). This technique was less effective in patients with limited chest expansion. Abdominal compression was also found to be useful during treatment of renal and upper ureteral stones in reducing overall patient movement. The decreased stone movement during extracorporeal shock wave lithotripsy with abdominal compression may increase stone fragmentation and may decrease the number of shocks per treatment.
