What is Weigert Meyer rule?
The Weigert-Meyer law states that ‘In a complete ureteral duplication, the ureter whose orifice is more medial and caudal reaches the upper moiety and the other ureter whose orifice is more lateral and cephalad reaches the lower renal moiety’. This law has been observed universally in cases of ureteral duplication.
How do you treat duplicate ureter?
Management and Treatment Most people do not need treatment. If needed, treatments include: Ureteroureterostomy: The ectopic ureter is split near your bladder, then sewn into the normal ureter of the lower part of your kidney. This allows urine from the upper part of the kidney to drain normally.
How common is it to have two ureters on one kidney?
Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, splits (or arises twice), resulting in two ureters draining a single kidney. It is the most common renal abnormality, occurring in approximately 1% of the population.
What is duplicating system?
Duplicated collecting systems (also known as duplex collecting systems) can be defined as renal units containing 2 pyelocaliceal systems that are associated with a single ureter or with double ureters. Duplication occurs when 2 separate ureteric buds arise from a single Wolffian duct.
What is a bifid ureter?
A bifid ureter is a congenital renal tract abnormality due to some error or disturbance during development. It is an example of incomplete duplication of urinary collecting system. A bifid ureter is formed when a duplex kidney drain into separate ureters that unite before attending the bladder.
Is it common to have 3 kidneys?
Having three kidneys is extremely rare, LiveScience says, with fewer than 100 cases reported in literature, according to a report in the Internet Journal of Radiology. The 2013 report says most people don’t realize they have a third kidney until it’s discovered through an unrelated medical test, like this patient’s.
What problems can a duplex kidney cause?
There is reason for concern when a duplex kidney is associated with urologic conditions requiring treatment. Duplex kidney may result in urine flowing back into the kidney rather into the bladder and also may cause obstruction of urine.
Do we have 2 ureters?
Most of us are born with 2 ureters, the tube that drains the urine from each kidney into the bladder. But some babies are born with 2 ureters that drain a single kidney.
What happens if you have a duplex kidney?
Duplex kidney may result in urine flowing back into the kidney rather into the bladder and also may cause obstruction of urine.
