ABSTRACT

Ureteropelvic junction obstruction has an incidence of 1:1,500 live births; it is usually diagnosed in prenatal ultrasounds between the 16-20th gestational week. We present the case of a three-year-old male patient who was attended at the emergency department of Hospital Metropolitano de Nuevo Leon (Mexico) for abdominal pain, fever and macroscopic hematuria. In the urine test were observed abundant eumorphic erythrocytes and bacteria. Ultrasound was performed in which severe hydronephrosis and ectasia of the left kidney were detected. The patient was given antibiotic therapy due to pielonephritis for seven days. In outpatient follow-up, in a CT scan we could determined a severe hydronephrosis and scarce renal parenchyma. In addition, it was verified the lack of drainage to the renal pelvis, so it was concluded that the patient had an ureteropelvic junction obstruction. The clinical presentation of this patient is rare since ureteropelvic junction obstructions are diagnosed in utero. In this particular case, it is probable that our patient had a grade I obstruction that went unnoticed. It is important to perform prenatal ultrasounds and to monitor these patients closely from the moment the diagnosis to prevent renal failure.
