Ectopic ureters are found in 1 of every 2000–4000 patients, [6] and can be difficult to diagnose, but are most often seen on CT scans. [7] Ectopic ureter is commonly a result of a duplicated renal collecting system, a duplex kidney with 2 ureters. In this case, usually one ureter drains correctly to the bladder, with the duplicated ureter ...
Duplicated ureter is the most common renal abnormality, occurring in approximately 1% of the population. [2] It occurs in about 0.7% of healthy adults and in 2% to 4% of people with urinary tract issues. [4] Race Duplicated ureter is more common in White Americans than in African-Americans. [citation needed] Sex Duplicated ureter is more common ...
A ureterocele is a congenital abnormality found in the ureter. In this condition the distal ureter balloons at its opening into the bladder, forming a sac-like pouch. It is most often associated with a duplicated collection system, where two ureters drain their respective kidney instead of one. Simple ureterocele, where the condition involves ...
Several conditions can result in urinary obstruction. In both adults and children, masses, such as abscesses and tumors, can compress the ureter. In children, hydronephrosis can be caused by ureteropelvic junction obstruction, ectopic inserted ureter, primary megaureter and posterior urethral valve (Figure 13).
An ectopic kidney is a kidney that is not located in its usual position . This condition results from the kidney failing to ascend from its origin in the true pelvis or from a superiorly ascended kidney located in the thorax. [1] It has an incidence of approximately 1/900. [2]
The abnormal anatomy can affect kidney drainage resulting in increased frequency of kidney stones and urinary tract infections as well as increase risk of certain renal cancers. [1] Fusion abnormalities of the kidney can be categorized into two groups: horseshoe kidney and crossed fused ectopia. The 'horseshoe kidney' is the most common renal ...
Assessment of the urinary tract for abnormalities such as blockage or narrowing, the presence of kidney stones, or tumours. [2] Use of duplex ultrasound to determine if there is backward flow of urine, for example in vesicoureteric reflux. Determination of how much urine is in the bladder, for example to assess for urinary retention.
Symptomatic patients typically present as middle-aged adults with renal colic, kidney stones, nephrocalcinosis and/or recurrent urinary tract infections; however, MSK also may affect children very rarely. In addition to the typical clinical phenotype of recurrent stone disease, other clinical profiles have now been recognized, that is, an ...
