Acute Pelvic Pain
Overview
Pelvic pain of sudden onset. Of women of reproductive age it is a ectopic pregnancy until proven otherwise. Refer immediately to gynaecology all patients with a pelvic mass, abnormal cervix, or persistent bleeding.
Definition
Chronic pelvic pain (CPP): refers to pain of at least six months’ duration that occurs below the umbilicus and is severe enough to cause functional disability or require treatment.
Acute pelvic pain: generally defined as pain in the lower abdomen or pelvis lasting less than three months. In women, it can pose a challenging clinical scenario in which history and physical examination findings are often nonspecific, and the clinical presentation of each condition can vary widely.
Acute pelvic pain – Gyaenacological
- Ectopic pregnancy
- Miscarriage
- Ovarian cyst rupture
- Ovarian torsion
- Ovarian haemorrhage
- Fallopian torsion
- Endometritis
- Pelvic Inflammatory Disease
- Mittelschmerz
Acute Pelvic Pain – Non-Gyaenacological
- Appendicitis
- Urinary stones
- Urinary Tract infection
In a pregnant woman these differential will be different as the pain might be due to the obstetric complications.
In Adolescents don’t forget transverse vaginal septum and imperforate hymen.
In postmenopausal women who present with acute pelvice pain, ectopic pregngnacy and ovarian torsion is unlikely.
Chronic Pelvic Pain will be discussed elsewhere
