First several physical tests are described by which the effect of electro-hydraulic
shocks on the mucosa of the urinary tract is examined. They are based on the experience
obtained from the electric lithotripsy of bladderstones with the Urat-1 apparatus.
The tests served primarily as a preparation for the first endoscopical crushings of
ureter stones. Two descriptions follow of ureterstones being crushed in a human. These
procedures were carried out successfully without any complications during or after
the operation, and without any ill after-effects. The first electric lithotripsy of
a ureterstone was performed in July 1969. It was done without anesthesia and the patient
was hospitalized for only one day.
