An ultrasound test that uses sterile saline to give a clear view of the inside of the uterus.
Saline infusion sonohysterography (SIS) is an ultrasound test in which sterile saline is gently introduced into the uterus through a thin catheter while ultrasound images are taken. The saline expands the cavity so the lining can be seen clearly.
It helps detect polyps, fibroids projecting into the cavity, adhesions and other structural abnormalities that may cause abnormal bleeding or affect fertility, without using radiation.
At Apollo Clinic Shyamnagar, the test is performed on a GE Voluson S10 ultrasound system, and the findings are explained to you in the same visit.
| Aspect | Details |
|---|---|
| Duration | 20–30 minutes |
| Preparation | Usually scheduled in the first half of your cycle, after bleeding stops; tell the staff about any infection or the possibility of pregnancy, and follow any pain relief advice given when booking |
| What Happens | A speculum is placed, a thin catheter is passed into the uterus, saline is gently introduced, and a transvaginal ultrasound probe captures images of the uterine cavity |
| Who It's For | Women with abnormal uterine bleeding, difficulty conceiving, repeated miscarriages or abnormalities seen on an earlier ultrasound |
SIS is recommended when the doctor needs a clearer look at the inside of the uterus than a standard ultrasound provides.

Radiation-Free ImagingSIS uses ultrasound and saline rather than X-rays, so there is no radiation exposure. | Clear Follow-UpFindings are explained in plain language, with a clear plan for treatment or further tests. | |
SIS uses ultrasound and saline to look at the uterine cavity, without radiation. HSG uses X-rays and contrast dye and is also used to check whether the fallopian tubes are open.
Many women feel cramping similar to period pain for a short time. Your doctor may advise pain relief beforehand.
It is not done during pregnancy or when there is a pelvic infection, so tell the staff about any possibility of pregnancy or symptoms such as fever or unusual discharge.
Mild cramps and light spotting for a day or two are common. Contact a doctor if you develop fever, severe pain or foul-smelling discharge.
