Late urologic sequelae after surgery for congenital sacrococcygeal teratoma

Forty-five patients treated for congenital sacrococcygeal teratoma were examined for late urologic outcome. The follow-up ranged from 4 to 42 (median 22) years. Only 8 patients experienced subjective urinary complaints. Sonography of the urinary tract revealed unilateral hydronephrosis in 2 patients, an ectopic kidney in 1, and a severely scarred kidney in 1; 1 patient had asymptomatic bacteriuria. Urodynamic screening using uroflowmetry was abnormal in 35 patients (78%). The risk of significant postoperative complications and subsequent late sequelae was greatest among patients with intrapelvic extension of the primary tumor.Supported by the Foundation for Pediatric Research, Helsinki, Finland
