The evaluation of suspected renal colic: ultrasound scan versus excretory urography.

Patients commonly present to the emergency department with a suspected diagnosis of renal colic. A prospective study of 98 patients presenting with acute flank or abdominal pain or both was conducted to determine the diagnostic accuracy of ultrasound scan compared with excretory urography for the diagnosis of urinary tract calculi. All patients underwent standardized ultrasound scan and excretory urography as independent procedures. Two staff radiologists who reported the procedures were blinded to the results of the other diagnostic test and ultimate clinical outcome. All patients discharged home from the ED were followed to the hospital urology clinic. The diagnosis of urinary calculus was made only by identification of calculus at surgery or by reported passage of a stone by the patient. Of 85 patients available for follow-up study (56 men, 29 women; mean age, 40.5 years; range 18 to 77 years), calculi were identified in 69 (81%). Ultrasound identified calculi in 44 patients (sensitivity, 64%; specificity, 100%). Excretory urography identified calculi in 44 patients (identical sensitivity and specificity). When the presence of obstructive hydronephrosis only was used to diagnose renal calculi, ultrasound scan identified 59 patients (sensitivity, 85%; specificity, 100%) and excretory urography identified 62 patients (sensitivity, 90%; specificity, 94%). When the results of both diagnostic modalities were combined, calculi were identified in 59 patients (sensitivity, 85%; specificity, 100%) and hydronephrosis was seen in 66 patients (sensitivity, 95%; specificity, 94%). Our study shows that the diagnostic abilities of these procedures are equal in the detection of renal calculi.(ABSTRACT TRUNCATED AT 250 WORDS)

Abbreviated Injury Scale and Injury Severity Score: a scoring chart.

The Abbreviated Injury Scale and the Injury Severity Score are important tools for grading the severity of injury to trauma patients. The Trauma Chart provided is a simple and concise guide for scoring and recording this useful information. The chart is useful in both a large wall-mounted form and in the reduced two-page form included in this article.

Perforation of a Meckel's diverticulum by a foreign body.

Perforation of a Meckel's diverticulum by a sharp object often presents with subtle nonspecific abdominal findings. A 53-year-old man had features resembling acute appendicitis and right ureteral obstruction. At laparotomy a wooden toothpick was found perforating a Meckel's diverticulum. The diagnosis of complicated Meckel's diverticulum should be considered when there is typical right lower quadrant pain or the patient is known to have ingested a sharp foreign body. The mortality resulting from perforation is low. The authors discuss other complications of Meckel's diverticulum.

Tourniquet syndrome caused by metallic bands: a new tool for removal.

Reported are two cases of metallic constricting devices presenting to our emergency department. A 40-year-old man was unable to remove a steel ring from his engorged penile shaft after autostimulation, and a 22-year-old man riveted a metallic nut onto his right index finger proximal to his distal interphalangeal joint. Both metallic devices were successfully removed by a new, easily managed, and readily available tool called the "Dremel Moto-Tool Kit" Cat. #280. Constricting devices around digits or the penis are not uncommon problems. Because of the inherent dangers and sequelae of delay in treatment, it is imperative that the removal of these devices is expedited.
