Summary  Pediatric urolithiasis may present with atypical symptoms what makes its diagnosis difficult. Its incidence is lower than in adults. A higher proportion of pediatric patients have a underlying condition that favors stone formation (metabolic, infectious, urinary tract anomalies, mixed). The objective of this paper is to describe the clinical features, treatment and outcome of children hospitalized with urolithiasis in Pereira Rossell Hospital. A retrospective an descriptive study between 1/6/2006 - 35/5/2012 was performed. All children between 1 month- 14 years hospitalized with urolithiasis were included. Twenty children were hospitalized, 12 were males, median age was 10years 7 months. Pain was the most common symptom (n:17) . Isolated lithiasis was seen in 11 patients and multiple lithiasis in 9. Lithiasis with pionephrosis was diagnosed in 2 children; nephrocalcinosis in 2. Obstructive complications were seen in 15 children, infections in 4 and mild renal failure in 3. Underlying conditions were seen in 13 children: metabolic (n:9), infections (n:4), urinary tract anomalies (n:3),partial metabolic studies were performed in 10 cases, complete in 3. In 10 patients surgery or lithotripsy was performed. Nephrectomy was necessary in children with staghorn calculus and pionephrosis. Follow up is still being done in 6 children; 3 persist with lithiasis , 2 have nephrocalcinosis, one of this last one has moderate renal failure. This is the first report of urolithiasis in hospitalized children in our country. Severe complications were seen in many children. It is important to improve the study of the underlying conditions and the follow up in order to achieve a better outcome and avoid renal failure.
