ABSTRACT
A ureterocele is a cystic dilatation of the terminal ureter. On the base of location of the orifice, ureteroceles are divided into simple and ectopic types. The simple ureteroceles arise from normally located ureteral orifice and are more common in adults than in children and relatively small. The ectopic ureteroceles arise from a ureteral opening in the bladder neck or urethra, some portion of the ballooning extending extravesically down into the urethra, and are related to the upper pole of a duplex system. Uncomplicated simple ureteroceles may be symptomless and need no treatment, but in cases complicated by stone, infection and stasis, excision of the ureterocele with ureteral reimplantation is recommended. Herein we report a case of simple ureterocele complicated by a stone in a 34 -year-old female, with a brief review of the literature.
