Travis Meyer

UreteroceleMost common in white females, most are left sided but 10% are bilateral

Duplicated Collecting Systems

• Can vary from 2 kidneys on one side with 2 ureters to one enlarged kidney with 2 ureters or one kidney with little enlargement and only a partial duplicated system of 2 proximal ureters joining to create one distal ureter.

• The upper pole ureter may be associated with a ureterocele and recurrent UTIs

• Malformations of the kidneys (or urinary system) should always raise suspicion of a malformation of the genital system

• In men: an absent seminal vesicle

• In women: an absent ovary, bicornuate uterus or malformed fallopian tube.

Weigert-Meyer rule (85%)•upper-pole ureter

•obstruction leads to hydronephrosis •inserts more inferiorly and medially in bladder •may insert into urethra, vagina, etc. •males not incontinent: insertion above ext. sphincter •associated with ureterocele

•lower-pole ureter •reflux leads to pyelonephritis
