[Extracorporeal shockwave lithotripsy (ESWL) as monotherapy using the Dornier HM-3 in staghorn kidney lithiasis. Effectiveness of the use of a double J catheter]. / Litotricia extracorpórea con ondas de choque (ESWL) como monoterapia con Dornier HM-3 en litiasis renales coraliformes. Utilidad del uso del catéter doble J.

The authors reviewed 110 cases of staghorn calculi (71 complete and 39 incomplete) from 693 cases of lithiasis that had been treated over a 15-month period at their hospital with the Dornier HM-3 lithotripter. Good results were achieved in 72.2% of the cases. One patient had a fall in hematocrit and a subcapsular hematoma which evolved well. Of the patients who did not have a double-J catheter, 33.6% had steinstrasse versus 27.9% of those who did. Because the complication rate is lower when double-J catheter placement is combined with ESWL this approach is recommended instead of PCN + ESWL.
