The distance from the tip of the retrograde catheter to the ureteropelvic junction is measured in centimeters with a tape measure. Percutaneous nephrostolithotomy allows fragmentation and removal of large calculi from the kidney and ureter. McKean SC, et al., eds. For example, the presence of a ureteropelvic junction (UPJ) obstruction or a ureteral stricture could make passing even very small stones difficult or impossible. Passing kidney stones can be quite painful, but the stones usually cause no permanent damage if they're recognized in a timely fashion. Plain abdominal x-ray versus computerized tomography screening: sensitivity for stone localization after nonenhanced spiral computerized tomography. After diagnosing renal (ureteral) colic, determine the presence or absence of obstruction or infection.

Accessed Jan. 20, 2020. Given that stones smaller than 3 mm are already associated with an 85% chance of spontaneous passage, MET is probably most useful for stones 3-10 mm in size, though many urologists would argue for the addition of MET with alpha-blockers even with smaller or proximal stones due to the relative in-expense and few side effects for patients undergoing trial of passage if it can potentially avoid need for operative intervention. All Rights Reserved. Sayer JA. [51] : Initial treatment of a renal colic patient in the ED starts with obtaining IV access to allow administration of fluid, analgesic, and antiemetic medications.
