cytology, gram stain and culture.
To insert or to remove IUCD or to check the threads.
2.colposcopy
 Binocular microscopy for direct visualization of
the cervix with magnification up to 60 times.
 For common clinical practice magnification of
13.5 is used.
 Some are equipped with camera for
photographic recording.
 Colposcopy is useful for
1,patiens with abnormal pap smear.
2,dietylstelbestrol exposed babies
 Colposcopy helps visualize cellular dysplasia
and vascular abnormalities and take biopsy.
 Colposcopy has decreased the need for cone
biopsy of the cervix which carries higher
morbidity and mortality.

peritoneal fluid from the cul-de-sac or pouch
of douglas.
• Indication-suspected ruptured ectopic preg,
pelvic abscess.
• Steps-done under sedation,pt in dorso
lithtomy position,vagina cleaned with
bethadine, vaginal speculum inserted,
posterior lip of cervix held with Allis
forceps,18 guage spinal needle fitted with
syringe is inserted 1cm below cervico -
vaginal junction in posterior fornix, after 2cm
insertion suction is applied.
• Interpretation-positive, negative, inconclusive.
9.Laparascopy.
• Visualization of peritoneal cavity by means
of fiber optic endoscope introduced through
abdominal wall.
• Indications:
• 1 –diagnostic=infertility,CPP,pelvic mass,to
diagnos acute pelvic
lesion,amenorrhea,mulleria
abnormalities,uterine perforation.

of the uterine tube for IVF
selection.salpingoscopy.

◦ infertility workup,
◦ correct timing of ovulation, guide for oocyte
retrieval,

 Evaluation of fetal growth
 Vaginal bleeding
 Determination of fetal presentation
 Suspected multiple pregnancy
 Adjunct to amniocentesis
 Discrepancy b/n GA by date fundal height
Indications continued
 Pelvic mass
 Suspected molar pregnancy
 Suspected ectopic pregnancy
 Suspected IUFD
 Suspected uterine anomalies
 IUCD localization
 Biophysical evaluation of fetal well being
 Assessment of amniotic fluid
Obs indications continued
 Adjunct to external cephalic version
 Estimation of fetal weight
 Abnormal serum alpha feto protein value
 Placental evaluation –localization, grading for
maturity.
 Screening for congenital anomalies-anencephaly
 Adjunct to Percutaneous umbilical blood
sampling
 Adjunct to intrauterine transfusion.
Gynecologic indication
 Pelvic pain including dysmenorrheal
 Pelvic mass
 Abnormal vaginal bleeding
 Amenorrhea, Infertility
 Confirm presence & check position of IUCD
 Diffuse abdominal pain
 Genital tract developmental abnormality
 Urinary or bladder symptoms
 Follicular monitoring in investigation of
infertility.
Computed tomography (CT scan).
11.
 Provides high resolution two di-mentional
images.
 Most useful in the diagnosis of lymph node
metastasis, depth of myometrial invasion.
 Cerebral metastasis of chorioca, micro adenoma
of pituitary.
 Has chance of surface radiation(2-10 CGY ).
 Locating pelvic absesses.pelvic
thrombophlebites,myometrial invasions by
endometrial ca.
12.Magnetic resonance imaging(MRI).
 Cross-sectional images of the body using combination of radio-
waves and magnetic fields.
 MRI is superior to CT in gynecology in delineation of pelvic organs
in multiple planes.
 Uses none ionized radiation no harm-full effect on body
 Excellent to diagnose congenital malformations of genital tract,f etal
congenital mal-formationes and morbid placental adherences.
