Patient's question:
My child told me that he was bleeding when he urinated, but the doctor said it was the nutcracker phenomenon. Is the nutcracker phenomenon a type of nephritis?Doctor's answer:
The nutcracker phenomenon is not nephritis; it is caused by the left renal vein compression syndrome, primarily seen in young males aged 13 to 16. If you want to carefully check whether it is the nutcracker phenomenon, you can undergo a CT scan or an abdominal color Doppler ultrasound. If occasional asymptomatic hematuria occurs, you can initially delay treatment and simply undergo periodic follow-up examinations. Over time, it may resolve on its own.
