GYN Pain Flashcards
Etiologies of Pelvic Pain
- Musculoskeletal
- Gynecological
- Urological
- Gastrointestinal
- Neurological
Causes of Acute Periumbilical Pain

Acute Pelvic Pain
- Requires aggressive management
- May be life threatening
Chronic Pelvic Pain
- Non-cyclical pain 6+mo in duration
- Localized to anatomic pelvis, anterior ABD wall at or below umbilicus, lumbosacral back/buttocks
- Of severity to cause disability and medical care
GYN Causes of Pelvic Pain: Pregnancy-related
- Ectopic pregnancy
- Threatened, inevitable, or incomplete miscarriage
- IUP with corpus luteum bleed
GYN Causes of Pelvic Pain: NOT Pregnancy-related
- Acute PID
- Rupture of ovarian cyst
- Adnexal torsion
- Degenerating/necrosing fibroids or ovarian tumors
- Primary dysmenorrhea
- Mittelschmerz
Non-GYN Causes of Pelvic Pain
- Appendicitis
- Diverticulitis
- IBS
- Urinary tract disorders (cystitis, pyelonephritis, renal calculi)
- Mesenteric lymphadenitis
Assessing Pelvic Pain
- Contraceptive Hx: Risk of PID or ectopic is reduced by 50% in patients taking oral contraceptives or using barrier methods
- Fever, chills, ABD/Pelvic involvement
- Vaginal/cervical discharge; cervical/uterine motion & tenderness; adnexal masses
PID: Risk Factors
- 15-25yo
- Sexual partner with symptoms of urethritis
- Prior Hx of PID
Conditions Associated w/Tender Adnexal Masses
- May indicate:
- Ectopic
- Tubo-ovarian abscess
- Cyst w/torsion
- Hemorrhage or rupture
- Abscess in appendix or colon
Conditions Associated with Uterine Enlargement
- Pregnancy
- Leiomyomas
- Adenomyosis
Lab/Diagnostic Tests for Pelvic Pain
- UPT
- CBC
- UA/Cultures
- GC/Chlamydia
- Pelvic US
- Diagnostic laparoscopy
Common Reproductive Pelvic Pain
- GI: Appendicitis; Bowel obstruction; diverticulitis; gastritis; inguinal hernia; IBS; mesenteric venous thrombosis; perirectal abscess
- GYN: Adenomyosis, degenerating/necrosing fibroid; ectopic; endometriosis; mittelschmertz; ovarian cyst/torsion; PID; tubo-ovarian abscess
- Urinary: Cystitis, pyelonephritis; lithiasis
- Other: AAA; lead poisoning; malingering; drug seeking; porphyria; SCD; somatization
Common Adolescent Pelvic Pain
- Similar to reproductive age
- Imperforate hymen
- Transverse vaginal septum
Common Postmenopausal Pelvic Pain
- Similar to reproductive pain minus ectopic and ovarian torsion
Common Pregnant Pelvic Pain
- Corpus luteum hematoma
- Ectopic
- Placental abruption
- Ovarian torsion
Common Postpartum Pelvic Pain
- Endometritis
- Ovarian vein thrombosis
Sonogram for Pelvic Pain
- Can exclude the Dx of ectopic
- Can Dx PID, ovarian torsion, acute appendicitis
CT for Pelvic Pain
- Can detect bowel, reproductive, and urinary disorders
- More sensitive than ABD X-ray
Acute Pelvic Pain + Reproductive Age
- Always assume a woman of reproductive age is pregnant until proven otherwise!!!
- Do Serum hCG or UPT: If (+) then determine location of pregnancy (IUP vs. ectopic)
Mgmt. of Ectopic Pregnancy
- Methotrexate 50mg/m2 IM
- Surgery
Ectopic Pregnancy: S/S
- Shock
- ABD pain
- Absence of menses or irregular vaginal bldg.
- Risks: PID (esp. w/chlamydia as causative organism)
PID: S/S
- Pain USUALLY bilateral
- Cervical motion tenderness
- Fever
- Cervical discharge
- May also have tubo-ovarian abscess
- Elevated ESR and CRP (more sensitive for PID than WBC or ESR)
Acute Appendicitis: S/S
- Leukocytosis, usually neutrophilia
- Periumbilical pain, migrating to RLQ
- septic inflammation
- N/V
- Anorexia
- Rebound tenderness
Ovarian Torsion: S/S
- Seen in adolescent and reproductive aged women
- Pain is progressive but may wax and wane w/ N/V
- Pain is USUALLY unilateral
- May have Hx of transitory pain
- Pelvic US can confirm
- Tx: Laparoscopy
Ruptured Corpus Luteal Cyst
- Bilateral or unilateral pain
- Pain cannot be distinguished from ectopic without hCG
- Self-limiting
- US for Dx
Chronic Pelvic Pain: S/S
- Non-cyclical pain of at least 6mo
- Localized to the pelvis, below the umbilicus and can include the anterior ABD wall, lower back, and buttocks
- Causes functional disability
- May require medical care
- May be r/t endometriosis or interstitial cystitis
- Many have Hx of Sexual or physical abuse
Chronic Pelvic Pain: Nerve Facts
- Pain arising from the visceral and somatic system
- Structures are supplied by thoracic spine and below
- Somatic pelvic pain (T12-S5)
- Visceral pelvic pain (T10-S5)
Chronic Pelvic Pain Differential Dx: GYN
- Endometriosis (most common cause of CPP)
- Adenomyosis
- Leiomyoma
- Adhesions
- Ovarian cyst
- Chronic PID
- Pelvic relaxation
- Endometrial/cervical polyps
- IUD
Chronic Pelvic Pain Differential Dx: Non-GYN
- Urological: Interstitial cystitis, urethral disorders
- Systemic: Fibromyalgia, depression, substance abuse
- GI: IBS, diverticulitis, Constipation, hernia, cancer
Endometriosis Management: 1st Line
- Expectant mgmt.: asymptomatic; no known prevention
- NSAIDs: for mild s/s (IBU 800 q6hr PRN; Naproxen 500mg then 250mg qid PRN)
- OCPs: minimal/mild s/s
- May give long cycles (3-4mo continuous without break)
- OCPs + NSAIDs
Endometriosis Management: 2nd Line
- Daily progestin (MDPA 5-10mg or NGS or NE)
- Depot MDPA IM q2wk for 2mo at 100mg/dose, then qmo for 4mo at 200mg/dose
- Mirena
- Danazol 200, 400, or 800mg/d for up to 6-9mo
- Side effects of hypoestrogenic state: acne, oily skin, deepening voice (not reversible), wt gain, edema and lipprotein changes
- Lupron or Zoladex (GnRHAs) good results
- hypoestrogenic state w/some bone loss (can do add-back therapy to prevent bone loss)
Endometriosis Management: Surgical
- Laparoscopy
- Hysterectomy
Endometriosis: S/S
- S/S vary
- Uterosacral ligament abnormalities:
- thickening
- focal tenderness
- lateral displacement of the cervix
- CMT
- Fixed retroverted uterus (common due to adhesions in cul-de-sac
