Urethral stones can be divided into primary and secondary types, and primary urethral stones are rare. In clinical practice, urethral stones often come from the urinary system, especially the bladder, and can also occur in the urethral rest room. In male patients, stones are mainly embedded in the urethra, urethral navicular fossa, or external urethral opening of the prostate. Patients with urethral stones have extremely fine urinary lines during urination, and may even experience urinary accumulation. In addition, the area where the stone is embedded is painful, accompanied by lower urinary tract infection. Frequent exposure to anterior urethral stones during diagnosis. Some patients may even see stones through the urethral opening, secondary stones in the urethral diverticulum, and there may be no discomfort or changes in urine flow during urination. However, there is secretion from the urethral opening, and stones can also be touched.
Possible hazards of urethral stones
(1) Urinary tract infection:
Urinary tract infections can be complicated by bacterial infections, and secondary infections caused by hydronephrosis can lead to renal abscess. Severe urinary tract infections can also cause sepsis and threaten human life. In addition, urinary tract infections promote the formation of stones, rapidly increasing the number of existing stones and forming a vicious cycle.
(2) Local damage:
Small stones can move freely in the urinary tract and easily abrade the urinary tract mucosa, causing bleeding and renal colic. However, this local damage is relatively mild. Large, relatively fixed or antler like urinary stones, although not in severe pain, can compress the urinary tract mucosa for a long time, causing epithelial detachment and tissue ulcers, resulting in adhesion between the stones and the ureteral wall. In severe cases, they may also cause cancer.
(3) Urinary tract obstruction:
Urethral stones can easily cause urinary tract obstruction. After urinary tract obstruction, the ureter and renal pelvis above the obstruction will expand and accumulate water. Hydronephrosis can be divided into mild, moderate, and severe hydronephrosis. When hydronephrosis occurs, the renal parenchyma is compressed, affecting renal function. If hydronephrosis is not resolved for a long time, it can cause the entire kidney to lose function. If there is obstruction in both sides of the urinary tract, it can lead to uremia. Why can't spinach be eaten for urethral stones? The main component of urethral stones is calcium oxalate. Normally, ordinary adults excrete 12 to 40 milligrams of oxalate from their urine every day. A portion of these oxalates come from food. If there is excessive intake of oxalates in the food, the calcium oxalate in the urine is too saturated, and the excess calcium oxalate crystals may be analyzed for stones in the urine.
