Straddle injury

18
Q

A

Straddle injury

19
Q

compression of the urethra against the inferior edge of the pubic symphysis.

A

Straddle injury

20
Q

What urethra is affected in straddle injury?

A

21
Q

long irregular stricture

A

23
Q

pancreatic enzymes jacking the urethra.

A

PAncreatic transplant urethral injury

This has been known to cause urethral injury, if the drainage is to the bladder (the old way of doing it).

24
Q

A

Condyloma Acuminatum

25
Urethrorectal Fistula occurs when?
post radiation Classically described in brachytherapy
26
esult of long term foley placement.
Urethral Diverticulum
27
Malignant tumors of the male urethra are rare. When they do occur, 80% are
Squamous cell tumors exception (prostatic urethra has TCC 90% of the time)
28
Cancer in a urethral diverticulum is nearly ALWAYS
Adenocarcinoma (rather than squamous cell)
29
Female + repeated UTI =
Urethral diverticulum
30
Urethral diverticulum Posterolateral wall M/3
31
Female urethral diverticulum often coexists with
stress ureinary incontinence (60%) and UTI
32
"Saddle-bagg" configuration
Female urethral diverticulum
33
What could develop within a urethral diverticulum in females?
stones = infection = irrittion = inc cancer risct = ADENOCA (60%)
