Echo-guided SWL of vesical stones with Dornier MPL 9000 lithotripter in obstructed and unobstructed patients.

Sixty-one patients with vesical stones (38 with underlying obstructive conditions and 23 unobstructed) underwent SWL using ultrasound targeting under no regional or general anesthesia. A foley catheter was not routinely employed, and the bladder was filled in a physiologic way. Complete resolution was obtained in 47 patients (78%); in particular, 66% of the obstructed patients and 96% of the unobstructed patients became stone free in one to four SWL sessions.

In situ echoguided extracorporeal shock wave lithotripsy of ureteric stones with the Dornier MPL 9000: a multicentric study group.

Objective: To study the efficacy of the Dornier MPL 9000 lithotripter with a real time ultrasound transducer in the localization and treatment of upper and prevesical ureteric stones.

Patients And Methods: Two-hundred and eighty-five patients with pre-vesical ureteric stones and 247 patients with upper ureteric stones underwent extracorporeal shock wave lithotripsy (ESWL) using ultrasound targeting, under no regional or general anaesthesia.

Results: At follow-up after 3 months 97% of patients with pre-vesical stones and 96% with upper ureteric stones were stone free.
