Living with Renal nutcracker syndrome
A condition in which the vein from the left kidney is squeezed, sometimes causing blood in the urine and flank pain.
Understanding Renal nutcracker syndrome
Some people have no symptoms, while others have severe and ongoing ones. In children, mild cases may be due to changes in body proportions with growth. GARD says it is less clear why it occurs or causes symptoms in adults. GARD lists onset in adulthood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Blood in the urine (hematuria)
- Flank pain
- Low back pain
- Abdominal pain
- Protein in the urine when standing (orthostatic proteinuria)
- Varicose veins or varicocele
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
