Male and Female Urinary Tracts
If a patient has a stone lodged higher in the urinary tract, the doctor may use a much finer calibre scope called a ureteroscope through the bladder and up into the ureter. (The ureter is the tube that carries urine from the kidney to the bladder). The doctor can then see the stone and remove it with a small basket at the end of a wire which is inserted through an extra tube in the ureteroscope. For larger stones, the doctor may also use the extra tube in the ureteroscope to extend a flexible fiber that carries a laser beam to break the stone into smaller pieces that can then pass out of the body in the urine.

Famous quotes containing the words male and, male, female and/or tracts:
“One of the most interesting and affecting things [on a difficult return march from a raid into Virginia] is the train of contrabands, old and young, male and female—one hundred to two hundred—toiling uncomplainingly along after and with the army.”
—Rutherford Birchard Hayes (1822–1893)
“Every modern male has, lying at the bottom of his psyche, a large, primitive being covered with hair down to his feet. Making contact with this Wild Man is the step the Eighties male or the Nineties male has yet to take. That bucketing-out process has yet to begin in our contemporary culture.”
—Robert Bly (b. 1926)
“Of all the riddles of a married life, said my father ... there is not one that has more intricacies in it than this—that from the very moment the mistress of the house is brought to [child]bed, every female in it ... becomes an inch taller for it....
I think rather, replied my uncle Toby, that ‘tis we who sink an inch lower.”
—Laurence Sterne (1713–1768)
“The opening of large tracts by the ice-cutters commonly causes a pond to break up earlier; for the water, agitated by the wind, even in cold weather, wears away the surrounding ice.”
—Henry David Thoreau (1817–1862)
