title: Ureteral calculus: experience with 521 stone extractions.
abstract: Few urologic problems require the consideration of so many factors as does an obstructing calculus in the ureter. The questions that arise in each case are whether an operation should be done for immediate relief of the obstruction or whether manipulation should be done, possibly subjecting the patient to a period of disability, painful attacks of colic and febrile reactions.
