Endoscopic ballistic lithotripsy in the treatment of bladder calculi in patients with neurogenic voiding dysfunction

Bladder stones represent a troublesome complication in patients suffering from neurogenic voiding dysfunction, in whom prompt and effective therapy is required, A variety of endoscopic lithotripsy methods are available; however, current devices can be tedious to use, We have treated 17 patients affected by bladder calculi and spinal cord injury or multiple sclerosis by means of the ballistic lithotripter EMS Swiss Lithoclast(R), The mean diameter of the stones was 2.7 cm, The mean operative time was 27 minutes, There were five intraoperative complications, including crises of autonomic dysreflexia (three patients) and light hematuria (two patients), There was no malfunction of the lithotripter and no long-term complications, All the patients were stone free at 6 months postoperatively, In conclusion, endoscopic lithotripsy with the ballistic lithotripter proved to be a very effective, rapid, and safe method for treating bladder calculi in patients with neurogenic bladders.
