[Nephro-urologic complications of presacral teratomas].
Neonatal presacral teratoma is a very unusual tumor. Because of its deep pelvic location and huge size, it can cause urinary obstruction and interfere with renal development during prenatal life. We have treated three patients and followed them up for six, three and one years. In all of them hydronephrosis and ureteral ectasia disappeared after excision of the tumor but some degree of calyceal club deformity persists in two patients. VUR persisted in one case for six years and was finally operated upon. Our last case has recently been operated for persistent left megaureter. This patient had also neonatal respiratory distress and mediastinal pneumothorax probably related to some degree of pulmonary hypoplasia. A close urologic follow-up is strongly advised in these patients.
