Genital Flashcards
Sacrococcygeal inspection for what in particular?
pilonidal dimpling and/or tufts of hair
Inspect anus for what?
- skin characteristics and tags

- fistulae
- prolapse
Palpate posterior surface of prostate for what?
- size
- contour
- consistency
- mobility
Palpation through anterior rectal wall in females for?
cervix and uterus
- size
- shape
- position
- smoothness
- mobility
Anal canal innervation (upper and lower)
- lower half: somatic sensory nn. (sensitive)
- upper half: autonomic control (insensitive)
Spaces between mucosal Columns of Morgagni in anus
crypts - anal glands empty into these
Hemorrhoid Types
- anastomosing veins cross the columns
- Zona hemorrhoidalis
- Internal hemorrhoids
- lower segment of anal canal
- venous plexus that drains into inferior rectal veins
- external hemorrhoids
Rectal storage of flatus and feces
- ampulla- stores flatus and feces
- Houston valves
- 3 semilunar transverse folds - lowest can be palpated
Prostate lobes
3: median sulcus w/ left and right lateral lobes
Infant and Child UG Development
- first stool 24-48h after birth - indicates anal patency
- gastrocolic reflex - stool after each feeding
- toilet training at 2-4 years
- prostate underdeveloped until puberty
Pregnancy Complications
- decreased GI motility - constipation
- pressure in veins below enlarged uterus
- hemorrhoids - aggravated by labor
Older Adult Complications
- degeneration of afferent neurons in rectal wall
- can’t relax anal sphincter
- increase pressure sensation threshold
- stool retention
- loss of sphincter tone - incontinence
- fibromuscular structures of prostate atrophy
- benign hyperplasia of glandular tissue
- loss of function of secretory alveoli
Genital/Rectal HPI
- changes in bowel function
- character, onset/duration, assoc. symptoms, meds: iron, lax.
- anal discomfort (itch, pain, sting, burn)
- related to postion/defecation, straining, blood/mucus, ADL disruption, meds: hemorrhoid creams
- rectal bleeding
- color, related to defication, amount, changes in stool, assoc. symptoms, meds: fiber, iron
- males (change in urinary fx)
- prostate hx, hesitancy/urgency/nocturia/stream/discharge, meds: antihist., anticholinergics, antidepressants, 5-alpha-reductase inhibitors
PMH
- hemorrhoids
- spinal cord injury
- prostate
- epesiotomy
- colorectal CA or related (breast, ovarian, endometrial)
FH
- rectal polyps
- family colon CA
- prostate CA
Personal/Social Hx
- travel history
- diet: fiber and animal fat
- MSM
- HPV vaccination
- alcohol

- use of complimentary/alternative therapies
- meds: prenatal vitamins, iron
Older Adult Personal Hx
- change in bowel habits or character
- assoc. symptoms
- dietary changes
- males: enlarged prostate and urinary symptoms
Prostate Exam
- size, contour, consistency, mobility, tenderness
- firm, smooth and slightly movable
- about 4cm in diameter
- 1cm protrusion normal
- greater protrusion denotes enlargement
- bogginess indicates BPH
loose hairs penetrating skin in sacrococcygeal area
pilonidal cyst
sign of HPV infection in anus
anal warts
(condyloma acuminata)
infection of soft tissue surrounding anal canal
ususally polymicrobial
perianal/perirectal abscess
tear in anal mucosa
anorectal fissure
inflammatory tract running from anus/rectum
to surface of perianal skin or other tissue
(caused by drainage of abscess)
anal fistula
