Men's urinal tracts are common channels for urination and fertilisation, with a total length of 16-22 cm, divided into three parts: prostate, membrane and sponge. Its physiological bends (lower shambones) and its three narrows (intra-urinary, membrane, exterior of the urethrope) are essential for clinical urine or instrumentation operations, while together with the urinary bicep control of urine and anti-reflective functions。
I. Inspection and structural characteristics
Prostate department (approximately 3 cm) 1.
In the prostate, the back wall has a plume and an opening of the ejaculation tube, which is the channel through which the semen is discharged. The cavity of the tube is wider, the mucous membranes form longitudinal wrinkles and are wrapped around prostate tissues, which can be suppressed when the prostate is increased, making urine difficult。
Membrane (shortest, approximately 1-2 cm).
Through the urine procretium, circumcised by the excised muscles of the urethromatic tract, the narrowest and fixed part of the urea. Owing to its position deep in the pelvis, external force impacts (e. G., cross-riding) are prone to fractures, triggering urine seepage。
Sponge body (maximum, approximately 15 cm) 3.
The sponges that pass through the urethroscope are divided into the urethroposphere (extended and prone to contusions) and the penis. The end of the penis is expanded into a canoe, open to the exterior of the urinal. The lower part of the mucous membrane contains a urinal gland, and the mucous lubricant is distributed。
Ii. Physiological function and organizational structure
Iii. Clinically related diseases and examinations
Infection and inflammation 1.
Urinitis is common in gonorrhoea or chlamydia, and is easily reversible due to exposure to the urine mucous membranes. Prostate urinary tractitis may spread to the prostate。
The urinal is narrow.
Fibrosis, often due to trauma or repeated infections, tends to be narrower than the membranes and ball, in the form of urination difficulties and thinning of urine。
Stones and alien objects 3.
Peatric stones are often embedded in a narrow body (e. G. Canoes or membranes) and are to be removed through a urea lens or surgery。
We're going to take a piss and check out 4.
It is necessary to remove the lower concussion of the shame and to avoid damage to the membrane. Utility imaging or urine lenses can assess narrowness, fistula or tumours。
Special attention
The mechanisms for diseases of the urinary system and the principles of diagnosis are better understood through an understanding of urinary anatomy and function。
