Urinary stones include stones in several parts of the body, such as kidney stones, ureteral stones, bladder stones and urethral stones. The symptoms are different depending on the location of the stones, which are mainly manifested as pain in the lower back and abdomen, hematuria, frequent urination, difficulty in urination, and so on.
1. Kidney stones: Due to the localized damage to the kidney caused by the stone, it may cause hematuria visible to the naked eye, and low back pain when blocking the renal pelvis and calyces causing fluid retention.
2. Ureteral stones: The presence of stones in the ureter causes frequent irritation to the ureteral wall, which usually causes renal colic, which is characterized by severe pain in the lower back and abdomen, which is unbearable to the patient, and is manifested by vomiting, paleness, and is accompanied by symptoms of frequent urination, urgency, and pain in urination.
3. Bladder stones: Due to the irritation of the bladder by the stones, it will cause the symptoms of lower abdominal pain, accompanied by difficulty in urination, hematuria, frequent urination, urinary urgency and other symptoms.
4. Urethral stones: the presence of stones in the urethra will cause irritation to the urethral mucosa and blockage of the urethra, which can cause urinary pain, difficulty in urination, frequent urination, urinary urgency, or even completely block the urethra causing urinary retention.
After the symptoms of urinary stones appear, it is necessary to seek medical examination and treatment as soon as possible to avoid serious complications.
