title: In situ extracorporeal shock wave lithotripsy for acute renal colic due to obstructing ureteral stones.
abstract: The purpose of the present study was to evaluate in situ extracorporeal shock wave lithotripsy (ESWL) for the treatment of obstructing ureteral stones causing acute renal colic. In situ ESWL with an EDAP LT-02 piezo-electric lithotriptor was used in a prospective study to treat 67 patients with obstructing ureteral stones causing acute renal colic. Patients were treated without anesthesia on an out-patient basis or during a one-day hospital stay. The overall one month stone-free rate was 94% (94% for proximal stones and 95% for distal stones). The overall success rate after a single ESWL session was 81%. Treatment was well tolerated in 90% (60/67) of patients. There was one case of non-obstructive pyelonephritis and one of ureteral edema. These rates compare well with published reports for delayed treatment in patients without renal colic. Immediate ESWL for cases of acute renal colic due to obstructing ureteral stones is an effective treatment strategy that warrants wider consideration.
