Intravenous urography (IVU), also referred to as intravenous pyelography (IVP) or excretory urography (EU), is a radiographic study of the renal parenchyma, pelvicalyceal system, ureters and the urinary bladder. This exam has been largely replaced by CT urography.

A stent is a small, metal mesh tube that acts as a scaffold to provide support inside the coronary artery. A balloon catheter, placed over a guide wire, is used to insert the stent into the narrowed artery. Once in place, the balloon is inflated and the stent expands to the size of the artery and holds it open.

Mean pain during stent removal was 4.8 out of 10 with 57% reporting moderate-to-severe pain levels of 4 or more. Removal by office cystoscopy resulted in the highest experienced pain (5.3). Thirty-two percent reported delayed severe pain after stent removal, including 9% who returned for emergency care.

After ureteroscopy the ureter will be inflamed and swollen. Sometimes the ureteral swelling will close off the ureter and block the flow of urine causing pain similar to (or worse than) when the stone was present. The stent keeps the ureter open and the urine flowing until the inflammation and swelling resolves.

Abstract. Some renal masses have higher attenuation than the surrounding renal parenchyma at computed tomography (CT). Their hyperattenuation is usually the result of proteinaceous fluid or densely packed cells. Most hyperattenuating renal masses are benign hemorrhagic or proteinaceous cysts.
