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 ...
In children, hydronephrosis can be caused by ureteropelvic junction obstruction, ectopic inserted ureter, primary megaureter and posterior urethral valve (Figure 13). In the latter, both kidneys will be affected. In adults, hydronephrosis can be caused by urolithiasis, obstructing the outlet of the renal pelvis or the ureter, and compression of ...
Its presentation is variable, often including abnormalities of the bony pelvis, pelvic floor, and genitalia. The underlying embryologic mechanism leading to bladder exstrophy is unknown, though it is thought to be in part due to failed reinforcement of the cloacal membrane by underlying mesoderm . [ 1 ]
Epispadias is a birth defect in which the urethra fails to fully develop, resulting in urine leaving the body from an abnormal site. [1] In males, this may be an opening on the upper aspect of the penis, [2] and in females when the urethra develops too far anteriorly. It occurs in around 1 in 120,000 male and 1 in 500,000 female births ...
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 ...
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.
A ureterovaginal fistula is a result of trauma, infection, pelvic surgery, radiation treatment and therapy, malignancy, or inflammatory bowel disease. Symptoms can be troubling for women especially since some clinicians delay treatment until inflammation is reduced and stronger tissue has formed. [2]
