Chemolysis through direct irrigation of the kidney has proved effective in the elimination of certain types of renal calculi, a West German investigator has reported.
"We consider the chemolytic method more effective than surgery for the treatment of recurrent stones of six months' duration or less," said Albert Timmermann, MD, director of the Minerva Institute and Clinic for Experimental Urology, Hamburg, and Research Fellow of the Max Planck Society.
One disadvantage, however, is the length of treatment time required, especially in the case of old and hardened stones, Timmermann added. Up to 800 hours has been required in some patients.
"Further investigation is being done in order to extend the application of the chemolytic method to all types of renal calculi," he told the 60th annual meeting in New Orleans of the American Urological Association.
Timmermann reported on a series of 260 patients treated with chemolysis over a five-year period.
