Abstract

Spontaneous steinstrasse ("stone street") is a collection of stones within the ureter and is a rare and understudied event. Factors such as infection, altered kidney function, and degree of obstruction are used to define the most adequate therapeutic option. Treatment can be either conservative or surgical. The decision of which depends on the clinical presentation. This paper reports a rare case of a 59-year-old patient with spontaneous steinstrasse examined at a urology clinic. Surgical intervention was required because of altered kidney function. The patient is currently undergoing follow-up for the metabolic investigation.
