Abstract

Extracorporeal Shockwave lithotripsy(ESWL)has changed management of urinary calculi considerably to a non invasive procedure.Nevertheless ureteral stones,especially those being impacted for a longer period in the ureter or very hard ones(e.g. calcium-oxalate-monohydrate or uric acid stones)are still a problem.Ureteral calculi comprise of up to 50% of all stones now and can cause considerable discomfort for the patient.Ureteroscopic manipulation with rigid instruments so far was only possible with rigid ultrasonic probes,baskets or forceps. The aim of our research was to develop an effective,secure and minimal invasive method for disintegration of urinary calculi.Thin flexible probes,which can be brought to the stone by small,preferably active flexible endoscopes should be used.High intensity laser energy,which can be transmitted through small quartz fibres seemed to be suitable.
