Why do men get urinary stones? How effective is laser lithotripsy in treating urinary calculi

Urinary calculus is the general name of calculus diseases in various parts of the urinary system, and is a common disease of the urinary system. According to the location of the stones, they can be divided into kidney stones, ureteral stones, bladder stones and urethral stones. The formation of this disease is closely related to environmental factors, systemic diseases and urinary system diseases. Its typical clinical manifestations include abdominal colic, hematuria, frequent urination, urgency of urination, pain in urination and other symptoms of urinary system obstruction and infection. What are the symptoms of urethral calculus?

Urethral calculus can also be divided into primary and secondary types. Primary urethral calculus is rare. Clinically, most of the stones that occur in the urethra come from the urinary system, especially the bladder, and can also occur in the urethral diverticulum. In male patients, the stones were mainly embedded in the urethra of the prostate, the navicular fossa of the urethra or the external urethral orifice. When patients with urethral calculus urinate, the urinary line is very thin, and even urine accumulation occurs. In addition, the stone incarceration site is painful, accompanied by lower urinary tract infection. When receiving diagnosis, they often contact with anterior urethral stones. Some patients can see the stones through the urethral orifice, and the secondary stones in the urethral rest room have no change in urine flow during urination, but there is secretion at the urethral orifice, which can also contact the stones.

What to do with urethral calculus

Treatment I

If the stones close to the external orifice of the urethra and the small stones in the navicular fossa cannot be removed by themselves, the liquid paraffin can be injected for extrusion, or the stones can be removed with pliers or tweezers. After injecting liquid paraffin into the anterior urethral calculus, push the calculus into the external orifice of the urethra by hand, and clamp the calculus with pliers and tweezers. You can also use the probe to pull out the stone, or bend the probe to hook out the stone. But the operation must be gentle to avoid serious injury to the urethra. For larger urethral stones or those embedded in the navicular fossa, if the above methods cannot work, the external orifice of the urethra can be cut, sterile liquid paraffin can be poured into the urethra, and then the stones can be removed by squeezing and clamping.

Treatment II

Anterior urethrotomy lithotomy can be performed for those who have severe incarceration of urethral stones before the operation and cannot be removed through the urethral orifice. There is a possibility of forming urinary fistula after urethrotomy of penis, so the method of urethrotomy and lithotomy should be avoided as far as possible. At this time, the stone can be pushed to the bulbous urethra, and the stone can be cut at the bulbous urethra as far as possible.
