What are the symptoms of ureteral stones? Four common symptoms of ureteral stones

Ureteral stones are one of the common diseases among women, also known as upper urinary tract stones. However, many women are not very clear about the symptoms of ureteral stones. Let us take a closer look at them below.

1. Urinary tract obstruction

Urinary tract obstruction is one of the common symptoms of ureteral stones. Urethral obstruction causes varying degrees of hydronephrosis and concurrent infection. Damage to the renal parenchyma may also cause pyelonephritis and renal abscess. The higher the stone is located, the more severe the obstruction, the longer the duration, the more severe the concurrent infection, and the more serious the kidney damage.

2. Impaired renal function

If ureteral stones are not treated for a long time, they will cause urinary flow obstruction and damage kidney function. The higher the location of the stone, the more severe the obstruction, the longer the time, the more severe the concurrent infection, and the more serious the kidney damage. Obstruction causes varying degrees of hydronephrosis, damages the renal parenchyma, and causes infection, pyelonephritis, and renal abscess.

3. Urethra pain

If the patient has obstruction in the middle and upper part of the ureter or the stone is in the process of moving downward, the patient will experience renal colic and microscopic hematuria, accompanied by symptoms of nausea and vomiting.

If the stone is stuck in the upper ureter, the pain will be in the waist and upper abdomen, and may even spread to the testicles or vulva.

In the middle section, the pain is usually in the waist and lower abdomen. Since the muscles of the lower ureter are connected to the bladder trigone and directly attached to the posterior urethra, patients with ureteral stones often have symptoms of frequent urination, urgency and pain, which cause great pain and inconvenience to patients.

4. Urinary tract infection

Stones can irritate and abrade the ureteral mucosa, causing bleeding and infection, leading to ureteral dilation, thinning of the ureteral wall, and more severe elongation and bending. The ureter at the site of stone impaction becomes fibrotic due to inflammation, causing tissue hyperplasia and thickening of the ureter, but cases of stones penetrating the ureter are extremely rare.

5. Other Impacts

In addition, stones may irritate or abrade the ureteral mucosa, causing bleeding, and may cause infection, leading to ureteral dilation, thinning of the tube wall, and more severe elongation and bending.

The ureter at the site of stone impaction becomes fibrotic due to inflammation, causing tissue hyperplasia and thickening of the ureter.
