The presumed cause: urinary calculi.

Severe consequences: renal failure, septic shock.

Urinary calculi are typically hematuria accompanied by sudden severe cramping in the lower back. The pain is often unbearable, and will spread to the thigh root. It can feel “channeling” pain, and the patient will have clinical symptoms such as profuse sweating and complexion changes. If kidney stones fall into the ureter, in addition to causing pain and hematuria, it can also cause hydronephrosis, which can lead to renal failure in the long run. If there is high fever and chills, it is likely to be co-infection, and septic shock may occur in severe cases.

Accompanied by frequent urination and dysuria

The presumed cause: cystitis.

Severe consequences: pyelonephritis, septic shock.

The normal bladder mucosa is a natural barrier against bacterial invasion. If this barrier is damaged, patients may experience symptoms such as hematuria, frequent urination, and dysuria. A ‘hot‘ pain when urinating that becomes more pronounced towards the end. Bleeding usually occurs at the end of the void or in the entire void.

Women are more prone to retrograde infections because of their short and straight urethra, causing cystitis.

For example, when pain, difficulty urinating, and palpable mass are present, it is already late, and the chance of early radical cure is lost, and the prognosis will be poor. For middle-aged and elderly people with hematuria, doctors will look for tumor cells in the urine or detect tumors early through B-ultrasound, and if necessary, biopsy can be used to confirm the diagnosis.

with puffy eyelids


The presumed cause: primary or secondary glomerular disease.

Severe consequences: uremia.

Hematuria in primary or secondary glomerular disease can accompany eyelid edema.

If normal people stay up late at night and don’t have a good rest, they will also have swollen eyes after getting up in the morning. But if the swelling does not go away or recurs repeatedly, or even extends to other parts, it is necessary to suspect that there is a problem with the kidneys.
