Few urethral diverticula are present at birth; the vast majority are acquired. Acquired urethral diverticula can be caused by trauma and/or infection. [1] When the peri-urethral ducts become infected repeatedly, they can become blocked and eventually cause a diverticulum.
Posterior urethral valves (PUV) is an obstruction at the level of the urethra. It occurs in approximately 1 in every 5000 to 8000 live births and only occurs in males. [ 1 ] Since PUV always affects both sides of the urinary tract, patients with posterior urethral valves are at the greatest risk for developing chronic kidney disease and end ...
A urethral diverticulum is located on the anterior vaginal wall, 1 to 3 cm inside the vaginal introitus. MRI is preferred as the imaging method of choice due to its excellent soft-tissue resolution. On T2-weighted imaging, it shows a high signal in the diverticulum due to the presence of fluid inside it.
The part of the urogenital sinus related to the bladder and urethra absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula. This gives rise to the trigone of the bladder and part of the prostatic urethra. The remainder of this part of the urogenital sinus forms the body of the bladder and part of the prostatic ...
Hypospadias is a common malformation in fetal development of the penis in which the urethra does not open from its usual location on the head of the penis. It is the second-most common birth defect of the male reproductive system, affecting about one of every 250 males at birth, [3] although when including milder cases, is found in up to 4% of newborn males.

The vesico-urethral portion is the deepest, continuous with the allantois. It absorbs the ends of the Wolffian ducts and the associated ends of the renal diverticula, and these give rise to the trigone of urinary bladder and part of the prostatic urethra .
The vesico-urethral portion is the deepest portion, continuous with the allantois. It absorbs the ends of the mesonephric ducts and the associated ends of the renal diverticula, and these give rise to the trigone of urinary bladder and part of the prostatic urethra .
Treatment is typically with a catheter either through the urethra or lower abdomen. [1] [3] Other treatments may include medication to decrease the size of the prostate, urethral dilation, a urethral stent, or surgery. [1] Males are more often affected than females. [1] In males over the age of 40 about 6 per 1,000 are affected a year. [1]
