Notification System for Overdue Radiology Recommendations Improves Rates of Follow-Up and Diagnosis.

OBJECTIVE. The purpose of this study was to quantify improved rates of follow-up and additional important diagnoses made after notification for overdue workups recommended by radiologists. MATERIALS AND METHODS. Standard reports from imaging studies performed at our institution from October through November 2016 were searched for the words "recommend" or "advised," yielding 9784 studies. Of these, 5245 were excluded, yielding 4539 studies; reports for 1599 of these 4539 consecutive studies were reviewed to identify firm or soft recommendations or findings requiring immediate management. If recommended follow-ups were incomplete within 1 month of the advised time, providers were notified. Compliance was calculated before and after notification and was compared using a one-sample test of proportion. RESULTS. Of 1599 patients, 92 were excluded because they had findings requiring immediate management, and 684 were excluded because of soft recommendations, yielding 823 patients. Of these patients, 125 were not yet overdue for follow-up and were excluded, and 18 were excluded because of death or transfer to another institution. Of the remaining 680 patients, follow-up was completed for 503 (74.0%). A total of 177 (26.0%) of the 680 patients were overdue for follow-up, and providers were notified. Of these 177 patients, 36 (20.3%) completed their follow-ups after notification, 34 (19.2%) had follow-up designated by the provider as nonindicated, and 107 (60.5%) were lost to follow-up, yielding four clinically important diagnoses: one biopsy-proven malignancy, one growing mass, and two thyroid nodules requiring biopsy. The rate of incomplete follow-ups after communication decreased from 26.0% (177/680) to 20.7% (141/680) (95% CI, 17.7-23.9%; p = .002), with a 20.4% reduction in relative risk of noncompliance, and 39.5% (70/177) of overdue cases were resolved when nonindicated studies were included. CONCLUSION. Notification of overdue imaging recommendations reduces incomplete follow-ups and yields clinically important diagnoses.

Recurrent infections related to an extruded ureteral stone in case of spontaneous ureteral rupture.

Spontaneous rupture of the ureter is a rare entity most commonly a result of ureteral stone disease. Despite the overall low prevalence, the diagnosis should be considered so appropriate imaging and management can be performed without delay. Although treatment has shifted towards more minimally invasive intervention and conservative management, open surgical intervention should be considered in certain situations to mitigate the risk of long-term complications. Here we present a unique case of spontaneous ureteral rupture complicated by recurrent infections and fistulous sinus tract formation.

Imaging of Gastrointestinal Tract Perforation.

Gastrointestinal tract perforation involving the stomach, duodenum, small intestine, or large bowel occurs as a result of full-thickness gastrointestinal wall injury with release of intraluminal contents into the peritoneal or retroperitoneal cavity. Most cases are associated with high mortality and morbidity, requiring urgent surgical evaluation. Initial patient presentations can be nonspecific with a broad differential, which can delay timely management. This article provides brief overviews of different causes of perforation. Various imaging modalities and protocols are discussed, along with direct and indirect imaging findings of perforation. Specific findings associated with different causes are also described to aid in the diagnosis.

Computed tomography (CT) in the evaluation of bladder and ureteral trauma: indications, technique, and diagnosis.

INTRODUCTION: Trauma to the genitourinary system includes blunt and penetrating injuries to bladder and ureters. These are rare injuries and are overlooked as other abdominal and pelvic injuries often take priority. Delayed diagnosis can lead to significant morbidity and mortality. Computed tomography has taken a central role in the imaging of the ureters and bladder. METHODS: This article reviews the anatomic relationships, mechanisms of injury, and clinical presentation to help physicians determine when bladder and ureteral injuries should be suspected and further imaging should be pursued. Radiologic evaluation of bladder and ureteral injury with CT cystography and CT urography, respectively, will be reviewed. CONCLUSION: CT cystography and CT urography are effective tools in identifying potentially serious injuries to the genitourinary system. Timely recognition of these injuries can be crucial for the overall management and prognosis.
