Current opinion in urology

Urolithiasis is a common urological problem, often requiring efficient workup, accurate diagnosis, and treatment. The purpose of this review is to summarize the imaging modalities employed for the diagnosis of calculi and the caveats of different clinical situations. ⋯ Considering the well supported accuracy and relative ease of use of noncontrast computed tomography, it has become a logical choice for the urologist to use the technique as a diagnostic tool for stone disease. The future of imaging for intervention and surveillance of stone disease lies in the continued progress of noncontrast computed tomography in terms of patient safety. This will need to be done by developing low-dose radiation computed tomography that can replicate the efficacy of current noncontrast computed tomography.

Researchers have recently sought out pharmacologic means of increasing rates of urinary stone passage. We outline the current understanding in medical expulsive therapy. ⋯ Medical expulsive therapy for ureteral stones provides a nonsurgical option for patients with ureteral stones. In view of the available clinical trials and meta-analysis, patients with distal ureteral stones measuring less than 1 cm who are candidates for observation warrant a trial of medical expulsive therapy.
