Which treatment in retrocaval ureter in children?

Retrocaval ureter is a rare condition in pediatric population. In this study, we present the diagnosis, therapeutic approach and follow-up of our two cases with retrocaval ureter. One of these underwent surgical correction due to persistent severe hydronephrosis and significant symptoms. We treated the second patient conservatively because, of moderate hydronephrosis and normal renal function with no symptoms. The treatment approach in patients associated with retrocaval ureter might be similar to these patients with UPJ-type hydronephrosis.
