OBJECTIVE: To understand the types and causes of the nutcracker phenomenon misdiagnosed clinically in order to improve the emphasis and diagnosis of the disease. Methods: Twenty-two cases were finally diagnosed as Nutcracker in Daxian People’s Hospital of Sichuan Province in 2000/2008, and the types and causes of misdiagnosis were retrospectively analyzed. Results: 6 cases were misdiagnosed as functional hematuria, 5 cases of acute nephritis, 4 cases of urinary tract infection, 4 cases of kidney stones, 2 cases of renal cyst and 1 case of prostate disease. Conclusion: Nutcracker phenomenon is one of the most important causes of hematuria. Because it is rare, clinical misdiagnosis is easily neglected and the understanding of the disease is enhanced, which helps to reduce the misdiagnosis and mistreatment of clinical symptoms.
