Feline ureteral obstructions are an increasingly recognised and challenging diagnostic and
management problem. Many cats with ureteral obstructions are critically ill at the time of …

Feline obstructive ureteral disease will likely remain a common and frustrating cause of
critical illness in cats for the foreseeable future. Since many cats are uraemic and …

Background Circumcaval ureters (CU) are a rare embryological malformation resulting in
ventral displacement of the caudal vena cava, which crosses the ureter, potentially causing …

Purpose This retrospective study aimed to report a multi-institutional experience with
laparoscopic and robotic-assisted repair of retrocaval ureter in children and to compare …

Preureteral vena cava (circumcaval ureter, retrocaval ureter) occurs in a third of the feline
population and has been associated with ureteral strictures in humans. The aim of this …

Objective: The aim of this study is to report on our last nine years' experience in the
diagnosis and treatment of retrocaval ureter. Methods: Eight patients with retrocaval ureter …

Retrocaval ureter and transposition of the caudal vena cava are each, rare developmental
anomalies. We describe the usefulness of static fluid magnetic resonance urography and …

Retrocaval ureter, terms are anatomically descriptive but misleading in regard to
development and results from altered vascular development. This anomaly is relatively …

Retrocaval ureter is abnormal looping of the proximal ureter behind the inferior vena cava.
The aberrant anatomy results in the compression of the ureter causing hydronephrosis. This …

In this chapter we discuss the embryology and the possible congenital anomalies of the
ureter. The ureter originates from the ureteric bud that grows from the caudal end of the …
