Randomized Controlled Trial Comparative Study Clinical TrialRenal 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 further imaging, length of hospital stay, urological intervention rates, radiation dosage and costs. ⋯ The incidence of alternative diagnoses was low, probably due to patient selection. Financial costs for each modality are comparable in a public tertiary hospital. Radiation dosages are higher for NECT and, for this reason, it might be appropriate to consider limiting NECT use to patients who have do not have classical symptoms of renal colic, to older patients and those with a contraindication to the administration of intravenous contrast media.

We determined the diagnostic value of urinalysis and plain films in patients with suspected renal colic presenting to an emergency department (ED). Over a 1-year period, 138 patients presented to the ED during the daytime with suspected renal colic, but for technical reasons the diagnostic modalities used in the study could be completed for only 99 patients, and 34 patients were lost to follow-up. A urinalysis; kidney, ureter, and bladder film; and spiral computed tomography (CT) were performed on each patient. ⋯ The sensitivity and specificity of CT in the diagnosis of urinary stones was 91%. Urinalysis and plain films are much less accurate than helical CT for confirming the diagnosis of acute urolithiasis. Further evaluation of the clinical and cost-effectiveness of helical CT should be done to determine its role in the work-up of these patients.

Low-dose unenhanced multidetector CT of patients with suspected renal colic.
This study is designed to assess the intraobserver and interobserver agreements and the diagnostic performances of low-dose unenhanced multidetector CT (MDCT) in patients with suspected renal colic. ⋯ Our study shows that low-dose unenhanced MDCT is appropriate for the diagnosis of ureteral stones, and that it provides excellent intraobserver and interobserver agreements and does not obscure alternative diagnoses.

Sequelae of infant colic: evidence of transient infant distress and absence of lasting effects on maternal mental health.
Colic is widely believed to remit by 3 months of age, with little lasting effect on the infant or the family. ⋯ This study provides support for the belief that, in most cases, colic is self-limiting and does not result in lasting effects to maternal mental health.

Infant colic: empirical evidence of the absence of an association with source of early infant nutrition.
The etiology of infant colic remains unknown, despite an abundance of research on the topic. ⋯ Breastfeeding did not have a protective effect on the development of colic. Although colic was statistically associated with several variables, including preexisting maternal anxiety, much of colic's etiology remains unexplained.
