ECTOPIC URETER - AN ADULT PRESENTATION

Abstract

ABSTRACT BACKGROUND Abnormalities
of ureteral development including
ectopic ureters and ureteroceles represent
a large component of clinical urology.
They continue to challenge clinical
management, despite their wide recognition
and well-defined surgical strategies.
The wide spectrum of involvement and
the variable patterns of presentation underlie
the clinical challenge and require a
thorough understanding of both normal
and abnormal embryology of the lower
urinary tract.The pathogenesis of ureteral
ectopia with or without a ureterocele
rests in ureterotrigonal and renal development.
This involves the common
nephric duct ,ureteral budding, ureterometanephric
interactions, and bladder
and trigone development. Ectopic ureters
can arise due to abnormal timing or location
of the primary ureteral budding from
the mesonephric ducts. That temporospatial
location will determine both the
character of the ureter incorporated into
the emerging bladder, as well as the
development of the trigone and kidney.
