• Ureterocele
• A ureterocele is a cystic out-pouching of the distal ureter into the urinary bladder.
• Affects the kidney, ureter, and bladder
• An abnormality that develops during embryo development
• It is present at birth but may not be discovered until later in life.
• There is no known prevention for this condition
• Ureterocele Background
• The clinical rate of ureteroceles has been found to be approximately 1 in 4000 pediatric admissions
• Occurring almost entirely in Caucasians and occurring four to six times more common in girls than in boys
• Anatomy
• In a typical urinary tract, each kidney is connected to one ureter.
• Ureters are paired muscular tubes traveling from the renal pelvis of the kidney to …show more content…
• Ureterocele
• Although most ureteroceles cause many of the same problems or issues, not all ureteroceles are identical
• A ureterocele has an appearance that of a thin-walled, often translucent, mass that can vary in size
• Ureteroceles can be contained within the bladder which is termed intravesical or they can extend outside the bladder, through the bladder neck and urethra which is termed ectopic or extravesical
• Explanation of Ureterocele
• The most commonly accepted theory behind ureterocele formation was first explained by Chwalla in 1927
• The ureteral bud (#2) presents a membrane called the Chwalla membrane at its junction with the mesonephric duct (#1)
• Normally, this membrane ruptures after the ureteral bud becomes incorporated into the urogenital sinus (#4) and separates from the mesonephric duct, allowing the passage of urine.
• If rupture of the Chwalla membrane is delayed, drainage of urine from the kidney will be obstructed and will result in expansion of the terminal ureteral portion, which in turn will cause a ureterocele
• Explanation of Ureterocele
• Another theory was explained by Tanagho in
