What is the urogenital sinus?

Urogenital sinus is a defect in your baby girl’s urinary and reproductive tract that happens during early fetal development and is present at birth. Normally, for a short period of time, the intestinal, reproductive and urinary tracts of your developing baby share a common cavity and opening.

What does urogenital sinus form in females?

Cells in these bulbs divide to form a solid vaginal plate, which extends and then canalizes (hollows) to form the inferior portion of the vagina. The female urogenital sinus also gives rise to the urethra and vestibule of the vagina.

Do human females have urogenital sinus?

Normally, the urethra and vagina are separate in females. In rare cases a birth defect causes the urethra and vagina to become one. This is known as urogenital sinus.

What is urogenital test?

Urogenital health testing may be done on samples/specimens collected from both males and females. Testing of this nature is often ordered when a patient is exhibiting symptoms of a chronic infection of the urogenital organs. Tests may also be ordered if a patient has a suspected sexually transmitted disease (STD).

Which condition is associated with bacterial infection of the bladder?

Cystitis (sis-TIE-tis) is the medical term for inflammation of the bladder. Most of the time, the inflammation is caused by a bacterial infection, and it’s called a urinary tract infection (UTI).

How is the urogenital sinus differentiated in males?

In males: Differentiation of the urogenital sinus. In studies of the urinary system we have seen that the cloaca is subdivided by the uro-rectal septum into the rectum (dorsal) and the primary urogenital sinus (ventral). The primitive urogenital sinus is in contact with the allantois.

Is the allantois in contact with the urogenital sinus?

The primitive urogenital sinus is in contact with the allantois. The upper part forms the future urinary bladder, while the middle and lower part forms the definitive urogenital sinus and, from it, the pelvic and phallic parts of the urethra (stage 17). Fig. 39. The cloaca subdivides.

When does the urogenital sinus begin to grow?

In the developing male, the fetal testis secretes testosterone into the fetal circulation at sufficient levels to stimulate the differentiation and growth of a portion of the urogenital sinus tissue, producing the definitive prostate gland. This usually begins during the first 3 months of fetal growth.

Is the urinary bladder part of the urogenital sinus?

After the partition, that (primitive) urogenital sinus is considered to become the urinary bladder and pelvic and phallic parts of the urogenital sinus (Wartenburg 1993; Moore and Persaud 1998), or bladder and definitive urogenital sinus (Sadler 1995), or pelvic urethra and definitive urogenital sinus (Larsen 1997).
