OHVIRA: What the Radiologist Needs to Know
Purpose or Case Report: 1. To describe imaging appearance of OHVIRA ( Obstructed hemivagina and ipsilateral renal agenesis) on different imaging modalities including Ultrasound, CT and MRI.
2. To understand the close interrelationship between urinary and reproductive system development during embryogenesis. Stress the importance of association of urinary and reproductive abnormalities so that if multicystic dysplastic kidney (MCDK), renal dysplasia or agenesis is seen in a female neonate, a careful search for associated genital malformation such as uterus didelphys with obstructed hemivagina (UDWOH) /OHVIRA should be performed.
3. To demonstrate the association of MCDK with OHVIRA and to further support the fact that renal agenesis seen in cases of OHVIRA may actually represent involuted MCDK rather than true renal agenesis.
4. To stress the importance of early diagnosis of OHVIRA (obstructed hemivagina with ipsilateral renal agenesis), so that correct management at the onset of puberty can prevent abdominal pain and dysmenorrhea and other complications.
Embryology of urinary and reproductive system will be discussed briefly. Imaging appearance of OHVIRA on different imaging modalities including US, CT and MRI with cases showing both prenatal and postnatal imaging will be presented.
Methods & Materials:

Conclusions:
