Retrocaval ureter: a case report and review of the literature.
Background: The retrocaval ureter is a rare congenital anomaly resulting from abnormal development of the inferior vena cava. The obstruction is usually at the retrocaval segment of the ureter, as it lies between the inferior vena cava and the body of the third lumbar vertebra. Computed tomography intravenous urography is the gold standard for investigating this condition and can reveal ipsilateral hydronephrosis and the fishhook sign or sickle sign of the proximal ureter, depending on the type of retrocaval ureter.
Case presentation: We present the case of a 30-year-old African female who presented with intermittent dull right flank pain for 3 years. Computed tomography intravenous urography revealed isolated moderate right hydronephrosis with a fishhook sign in the proximal ureter. Surgical correction was performed, and the patient was followed for 6 months with improved renal function.
Conclusion: Surgery remains the sole definitive management of the retrocaval ureter for symptomatic patients and those with worsening hydronephrosis or differential renal function.
期刊介绍：
JMCR is an open access, peer-reviewed online journal that will consider any original case report that expands the field of general medical knowledge. Reports should show one of the following: 1. Unreported or unusual side effects or adverse interactions involving medications 2. Unexpected or unusual presentations of a disease 3. New associations or variations in disease processes 4. Presentations, diagnoses and/or management of new and emerging diseases 5. An unexpected association between diseases or symptoms 6. An unexpected event in the course of observing or treating a patient 7. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect
