Abstract
Of all ureteral calculi 20 per cent will require removal. The use of extracorporeal shock wave lithotripsy has changed dramatically the treatment of ureteral stones requiring intervention. We reviewed 111 procedures for 108 stones in 100 consecutive patients. Primary techniques included extracorporeal shock wave lithotripsy after retrograde manipulation (63 cases), percutaneous nephrolithotomy alone (1) and after retrograde manipulation (3), ureteroscopic removal (29), cystoscopic removal (2) and open ureterolithotomy (2). These techniques and the results are discussed. Of the patients 11 required a secondary procedure, including extracorporeal shock wave lithotripsy in 3, ureterorenoscopy for failed extracorporeal shock wave lithotripsy in 2, an open operation for complications of ureterorenoscopy in 2 and correction of associated stricture in 2. All patients ultimately were free of stones. Our experience with in situ extracorporeal shock wave lithotripsy is described. An open operation was done only when less invasive forms of treatment failed or electively to correct an associated anatomical abnormality.
