The gatekeeper disparity--why do some medical schools send more medical students into urology?

Purpose: Urology continues to be a highly desirable specialty despite decreasing exposure of students to urology in American medical schools. We assessed how American medical schools compare to each other in regard to the number of students that each sends into urological training. We evaluated the reasons why some medical schools consistently send more students into urology than others.

Radiographic characteristics of sulfadiazine urolithiasis.

Sulfadiazine-related stones are uncommonly reported, but they could be increasingly encountered owing to the use of sulfadiazine for human immunodeficiency virus-related toxoplasmosis. We report on their unusual imaging characteristics, with 4 such stones having very low attenuation compared with more commonly encountered stones. Because their atypical appearance resulted in delayed treatment for our patient in acute renal failure and because the computed tomography imaging characteristics have not been previously defined, we report the findings of stone analysis-confirmed sulfadiazine-related urolithiasis.

Gadolinium-enhanced computed tomography cystogram to diagnose bladder augment rupture in patients with iodine sensitivity.

Anaphylactic reaction to iodinated contrast is a potentially life-threatening complication of diagnostic imaging studies. We report the successful use of gadolinium as an alternative contrast agent for computed tomography cystogram in a patient with a history of anaphylactic reaction to iodinated contrast. This technique allowed us rapidly to diagnose a rupture of her bladder augmentation and pursue operative repair.
