The incidence is 1/254000. The serum copper level is lower than normal ranges. Copper is an important trace element which is necessary for lysyl oxidase and many other enzymes. Lysyl oxidase deficiency is associated with fragility in connective tissue and vascular abnormalities. The deficiency of this enzyme plays the major role in urologic abnormalities appeared in Menkes disease. Most frequent urologic abnormalities detected are bladder diverticula, vesicoureteral reflux and hydronephrosis. MATERIAL AND METHODS Two year old boy with Menkes disease is evaluated because of recurrent urinary tract infection and bilateral diverticula of the bladder is detected in voiding cystourethrography. The ureteral orifices were placed within the diverticula in cystoscopy. Intravesical bilateral diverticulectomy and bilateral ureteroneocystostomy are performed. The postoperative period was uneventful. On control cystos- copy there was no recurrence. RESULTS Lysyl oxidase is a copper dependent enzyme and is responsible for the morphology of the elastic fibers in connective tissue. The most frequent urologic abnormality caused in its deficiency in Menkes disease is bladder diverticula. The reported incidence is 1,7 %. The urologic abnormalities cannot be prevented but their onset may be delayed by parenteral copper treatment. The diagnosis is made by voiding cystourethrography. The choice of treatment is surgical excision. Although it is reported that the diverticula in Menkes disease are not correlated with the ureter orifices that was not the situation in our case and bilateral ureteroneocystostomy was also performed. 14:06–14:08 S2-4 (CP) UROTHELIAL TUMORS OF THE BLADDER IN CHILDREN Alice FAURE, Abdulrahman ARAFAH, Jean-Michel GUYS and Thierry MERROT Hôpital La Timone Enfant, Paediatric surgery, Marseille, FRANCE PURPOSE Urothelial tumors of the bladder are uncommon in pediatric population, rarely happening in the first two decades of life, and exceptional under 10 years of age. Here, we reported 7 cases regarding clinical outcomes. MATERIAL AND METHODS We retrospectively identified 7 patients 7 to 15 years old (median: 12 years) with urothelial tumors managed in our center, since 2004. The presentation, diagnostic procedure, treatment and outcome. Finally, we reviewed the literature to analyze the outcomes and follow-up in the pediatric population.
