Ureteroscopy

A ureteroscopy is an examination or procedure using a ureteroscope. A ureteroscope, like a cystoscope, is an instrument for examining the inside of the urinary tract. A ureteroscope is longer and thinner than a cystoscope and is used to see beyond the bladder into the ureters, the tubes that carry urine from the kidneys to the bladder. Some ureteroscopes are flexible like a thin, long straw. Others are more rigid and firm. Through the ureteroscope, the doctor can see a stone in the ureter and then remove it with a small basket at the end of a wire inserted through an extra channel in the ureteroscope. Another way to treat a stone through a ureteroscope is to extend a flexible fiber through the scope up to the stone and then, with a laser beam shone through the fiber, break the stone into smaller pieces that can then pass out of the body in the urine. How and what the doctor will do is determined by the location, size, and composition of the stone.
