urinary lithiasis is a rare disease in children if compared with its incidence on the adults.
to describe the results of the treatment of urinary lithiasis in children in Cuba, by using extracorporeal shock wave lithrotripsy, and to validate the efficacy of this method.
Methods: a sample of 227 children treated at the Center of Urinary Lithiasis Treatment in "Hermanos Ameijeiras" hospital of Havana, Cuba, from April 1986 to October 2011. Three types of lithotripters were used: HM3 (Dornier), Lithostar Plus (Siemens) y Medical Modulith® SLX (Storz).
Results: the ages ranged from 2 to 18 years. The numbers of treated females and males were similar (51 % and 49 %). The prevailing symptom was nephritic colic with renal calculi (81.9 %) and in the urether (18.1 %). The mean affected surface was 1.20 cm2. General orotracheal(34.4 %) and general intravenous (65.6 %) types of anesthesia were used. Eight cases (3.52 %) required repeated treatment. The complications were acute urinary infection (3.08 %) and renal subcapsular hematoma (0.88 %). Lithiasis was eliminated in 96.04 % of patients.
Conclusions: this therapy based on extracorporeal shock wave lithotripsy proved to be effective, with low mortality and serious complication rates, so it should be scientifically defended as the first therapeutic option in the elimination of urolithiasis at these ages. It must be remembered that the elimination of calculi is not enough since the disease must be identified, treated in depth, and relapses must be avoided.
