1-week-old boy is evaluated in the hospital. The patient has been admitted due to urosepsis and is receiving antibiotic therapy. The mother received no prenatal care; the neonate was born at term via spontaneous vaginal delivery. Vital signs are normal. Examination shows lower abdominal distension with normal bowel sounds. The penis and scrotum appear normal. Renal ultrasonography and voiding cystourethrography reveal a diffusely thickened bladder wall with bilateral vesicoureteral reflux and hydronephrosis. Which of the following is the most likely cause of this patient's findings? Congenitally short intravesical ureters Failed obliteration of the allantois Fusion of the bilateral metanephros Persistence of the urogenital membrane Stenosis at the ureteropelvic junction
