Q: What is the obstetric score of a 26-year-old woman who is 36 weeks pregnant, has had one previous delivery of twins, and is certain of her dates?

G2P1L2 (2 live births). ***G2P1L2 (2 live births)*** - **Gravida (G)** refers to the total number of pregnancies, including the current one. This woman is currently pregnant and has had one previous pregnancy, making her G2. - **Parity (P)** refers to the number of pregnancies that reached viability (>20 weeks gestation or >500g), *regardless of the number of fetuses*. She had one previous delivery (twins) that reached viability, so her P is 1. The current pregnancy is not included in parity until after delivery. - **Live births (L)** refers to the number of live children delivered. Her previous pregnancy resulted in twins, meaning 2 live births. *G3P2L2 (3 pregnancies, 2 live births)* - This option incorrectly counts the number of pregnancies (**G**) as 3. She has had one previous pregnancy and is currently pregnant, totaling 2 pregnancies. - It also incorrectly counts the parity (**P**) as 2. Parity refers to the number of deliveries that reached viability, not the number of fetuses. Her previous delivery was a single event, making P1. *G2P2L2 (2 pregnancies, 2 live births)* - While the Gravida (G2) and Live births (L2) are correct, the Parity (**P**) is incorrectly stated as 2. Parity refers to the number of viable pregnancies delivered, and she has only had one previous delivery. - The number of fetuses (twins) does not increase the parity count for a single delivery event. *G3P3L2 (3 pregnancies, 3 live births)* - This option incorrectly states the number of pregnancies (**G**) as 3 and the parity (**P**) as 3. - The woman has only had one previous pregnancy and is currently pregnant, for a total of G2 and P1.

Q: What is the best treatment option for a septate uterus?

Transcervical hysteroscopic resection of the septum. ***Transcervical hysteroscopic resection of the septum*** - This procedure involves using a **hysteroscope** to visualize and resect the **fibrous or muscular septum** that divides the uterine cavity, restoring a normal uterine shape. - It is considered the gold standard due to its **minimally invasive nature**, effectiveness in improving reproductive outcomes, and lower risk of complications compared to abdominal approaches. *Tompkins Metroplasty* - This is an **abdominal surgical procedure** primarily used for the repair of a **bicornuate uterus**, not typically for a septate uterus. - It involves resecting the uterine fundus to create a single uterine cavity, which is more invasive than hysteroscopic septum resection. *Jones metroplasty* - This procedure is also an **abdominal approach** used for the surgical correction of a **bicornuate uterus**, not a septate uterus. - It involves excising the septal portion and approximating the uterine walls. *Strassmann metroplasty* - This is another **abdominal surgical technique** that is primarily indicated for the repair of a **bicornuate or didelphys uterus**, where a large defect needs to be corrected. - It involves reconstructing the uterus through a fundal incision, which is significantly more invasive than hysteroscopic septal resection for a septate uterus.

Q: A 22-year-old primigravida visits ANC OPD with 20 weeks POG. On examination uterine height reveals a 16-week size. USG shows reduced liquor. What will be the diagnosis?

Bilateral renal agenesis. ***Renal agenesis*** - **Bilateral renal agenesis** leads to **oligohydramnios** because the fetal kidneys are the primary producers of amniotic fluid after 16 weeks of gestation. - The reduced amniotic fluid (liquor) is consistent with the decreased uterine size (16-week size at 20 weeks POG) and is a hallmark of this condition, often resulting in **Potter sequence**. *Bartter’s syndrome* - This is a rare, inherited renal tubulopathy characterized by significant electrolyte disturbances (hypokalemia, metabolic alkalosis, hypercalciuria) due to impaired ion transport. - While it affects kidney function, it does not typically cause severe **oligohydramnios** or **renal agenesis** and would not explain the small uterine size in this scenario. *Liddle syndrome* - This is a rare genetic disorder characterized by early-onset hypertension, hypokalemia, and metabolic alkalosis, due to constitutive activation of the epithelial sodium channel (ENaC) in the collecting ducts. - It does not involve structural kidney abnormalities or significantly impact amniotic fluid volume during pregnancy to cause the described findings. *Fetal anemia* - Fetal anemia can lead to complications such as **hydrops fetalis**, which would typically cause **polyhydramnios** or a uterine size larger than expected due to fluid accumulation, not oligohydramnios or a smaller uterine size. - Reduced liquor and a small uterine size are not characteristic presentations of fetal anemia.

Q: What will be the Hysterosalpingogram (HSG) finding?

Hydrosalpinx. ***Hydrosalpinx*** - The image, likely a hysterosalpingogram (HSG), shows a **dilated and fluid-filled fallopian tube** with no spillage of contrast into the peritoneal cavity, which is characteristic of hydrosalpinx. - The **contrast media fills the tubal lumen** but is unable to egress, indicating distal tubal obstruction and fluid accumulation. *Cornual block* - A cornual block would present as **obstruction at the uterine ostium** of the fallopian tube, preventing contrast from entering the tubal lumen. - In this image, contrast has clearly entered and dilated the fallopian tube, ruling out a cornual block. *Normal findings* - Normal HSG findings would show **patent fallopian tubes** with free spill of contrast into the peritoneal cavity. - The visible **dilation** and **lack of spill** in the image are distinctly abnormal. *Bicornuate uterus* - A bicornuate uterus is a **congenital uterine anomaly** characterized by two separate uterine horns. - While the uterus appears somewhat irregular, the dominant feature is the dilated fallopian tube, which is not a hallmark of a bicornuate uterus.
