INTRAVENOUS PYELOGRAPHY

Value of routine intravenous pyelography in the investigation of hypertension.

Bright in 1836 first described the course of chronic nephritis, and Mahomed in 1874 in his Paper entitled 'The Pre-albumenuric Stage of Bright's Disease' drew attention to the association of this disease with high arterial tension. It has since been well established that renal disease of many kinds predisposes to arterial hypertension (Longcope and Winkenweider, 1933; Pickering and Heptinstall,...

Renal colic: a prospective evaluation of non-enhanced spiral CT versus intravenous pyelography.

The aim of this study was to compare non-enhanced spiral CT (NECT) and intravenous pyelography (IVP) in patients with suspected acute renal colic. Two-hundred patients presenting to the Emergency Department with suspected acute renal colic were randomized into groups undergoing NECT or IVP. The main outcome measures were diagnostic utility, incidence of alternative diagnoses, requirement for fu...

Effect of N-acetyl cysteine in prevention of contrast nephropathy on patients under intravenous pyelography and contrast CT

BACKGROUND Contrast nephropathy is a common and often reversible cause of acute renal failure (ARF). About 10% of ARF in admitted patients might be due to it and may also lead to dialysis. Some methods could prevent it such as fluid therapy with half or normal saline, Na bicarbonate, N-acetyl cysteine (NAC), and so on. The aim of this study was to evaluate the efficacy of NAC to prevent contras...

The accuracy of noncontrast helical computed tomography versus intravenous pyelography in the diagnosis of suspected acute urolithiasis: a meta-analysis.

STUDY OBJECTIVES We determine the accuracy of noncontrast helical computed tomography (NHCT) compared with that of intravenous pyelography (IVP) in diagnosing acute urolithiasis. METHODS Computerized searches of MEDLINE and EMBASE were combined with hand reviews of major journals and of articles from reference lists. Articles were assessed according to a priori criteria for inclusion. Study e...
