Ureteroscopy (URS)

The procedure is performed to remove large stones from the ureter, a vital part of the urinary system. Ureteric stones, also known as calculi, are a relatively common condition affecting approximately 10% of the global population. These stones form when kidney stones migrate into the ureter, the tube connecting the kidney to the bladder. The presence of ureteric stones can lead to acute and excruciating pain. While smaller stones can be naturally expelled through urine, larger stones can cause the kidneys to swell, a condition known as hydronephrosis. If left untreated, the kidney may ultimately be lost.


Several risk factors contribute to the development of ureteric stones. Genetics play a role, as individuals with a family history of kidney stones are more prone to developing them. Additionally, inadequate water intake can contribute to stone formation, as it reduces the volume of urine and increases the concentration of substances that can crystallize and form stones. Chronic urinary tract infections also increase the risk of developing ureteric stones. Furthermore, the consumption of certain foods that contain substances known to promote the formation of particles in the urine can contribute to the development of these stones.


It is crucial to address these risk factors and seek appropriate medical intervention to prevent the complications associated with ureteric stones. By adopting a professional tone, we can effectively communicate the importance of understanding this condition and taking proactive measures to maintain urinary health.
