This report presents a bizarre and unusual case of looping and entrapment of a hydrophilic guidewire in the ureter of a 65-year-old woman with a stone in the lower ureter at the time of ureteroscopy and laser lithotripsy. We describe endourology maneuvers to remove the retained guidewire. Looping and entrapment of guidewire is a rare complication that urologists may face when they do not follow the basic principles of guidewire insertion.

Evidence Acquisition: We performed a literature search on Medline according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement up to December 2015 using the following key words: urolithiasis prevalence, recurrent urinary stone, metabolic syndrome and urolithiasis, urinary stone/urolithiasis metabolic evaluation, shockwave lithotripsy, ureterorenoscopy, percutaneous nephrolithotomy/nephrolitholapaxy. The key words were chosen following consensus as the single most appropriate and descriptive terms that would yield maximal relevant results in a single search for each section.
Diagnosis of small prostate cancer foci is a real challenge for pathologists and urologists as it carries the risk of false positive or negative diagnosis with clinical consequences. Diagnosis of small prostate cancer foci requires a strict methodological approach which includes a search for major and minor features under low and high magnification. Ambiguous cases can be further clarified with the use of basal cell immunomarkers complemented by a positive indicator of malignancy.

Core needle biopsies are now among the most common specimens received from pathology laboratories. As a result, urologists and pathologists may encounter small volume prostate tumors with obvious clinical and diagnostic implications.
