Detection of Ureteral Stones With Transvaginal Sonography

Abstract

Transabdominal sonography has proved to be an efficacious imaging technology to diagnose urolithiaisis. However, the location of the calculus may cause a sonographic examination to be limited. Since the majority of ureteral stones are located in the distal ureter, calculi may not always be visualized transabdominally, especially if the bladder is not full. This case study demonstrates the use of transvaginal sonography in the diagnosis of distal ureterolithiasis and discusses the optimal visualization of a ureteral stone in a female patient using transvaginal sonography. The case demonstrates the importance of this imaging method when distal urinary tract stones are suspected.
