Introduction: A detailed knowledge of normal branching pattern of intrahepatic bile duct and their variations is of utmost importance for any liver or biliary tract surgery to avoid severe post-surgery complications and morbidity. The objective of this study was to evaluate variations of intrahepatic bile ducts in Magnetic Resonance Cholangiopancreatography (MRCP) examinations in Nepalese population.Methods: This quantitative, cross sectional study was performed in patients referred for MRCP examinations for various clinical indications to Tribhuvan University Teaching Hospital, Maharajgunj, Nepal. Data were collected for a period of four months from August to November 2019 after IRB approval. Convenience sampling was employed and a total of 90 examinations were included. Data were obtained from the 1.5T Magnetom Amira Siemens MRI scanner. The 3D MRCP images were visually analyzed and classified into 7 Types according to the classification given by Choi et al.Results: In our study 47.8% patients had Type 1/normal IHBD (n=43). 20% had Type 2 (n=18), 3.3% had Type 3A (n=3), 5.6% had Type 3B. Type 5A (n=5), 7.8% had 5B (n=7), 3.3% had Type 6 (n=3) and 6.7% had Type 7 (n=6). No patients were found to have Type 3C and Type 4 IHBD variation. Among the total number of Type 1 cases, 67.44% (n=29) were female and rest were male.Conclusions: Typical IHBD was only found in a 47.8% patients and common other variations were also noted in our population. Type 2 and Type 5B were found in 20% and 7.8% patients respectively.
The average post void urine volume was 48 ml in persons with normal sized prostate. The post void volume increased with increasing prostate size as well as with inner gland volume. No correlation between age and post void residual volume was seen. CONCLUSIONS: These results based on randomly selected persons suggested little variation in post void residual urine volume with age. However a somewhat stronger correlation was found between residual urine and prostate volume and inner gland size.
Introduction: Various organs are measured to estimate the gestational age of fetus. Sonographically derived parameters used to date pregnancy include crown rump length, biparietal diameter, head circumference, femoral length and abdominal circumference. Fetal kidney length, transcerebellar diameter and placental thickness are emerging as new parameters and are claiming to be more accurate in certain situations. In Nepalese context fetal kidney length has not been studied yet so this study was done to fill this need.
Methods: Obstetric sonography was performed in 108 pregnant women with uncomplicated pregnancy to evaluate the efficacy of FKL as a measure to calculate the predicted gestational age. Gestational age ranged from 20 weeks to term. Only patient with known LMP and previous history of normal menstrual cycle were included in the study.
Results: The study showed mean fetal kidney length at 20 - 24, 25 - 29, 30 - 34 and 35 - 37 weeks gestation as 22.5 ± 0.5, 26.9 ± 0.7, 32.32 ± 0.7 and 36.3 ± 0.6 respectively. Overall in combined second and third trimester, fetal kidney length showed strong linear correlation with gestation age with highest significant Pearson correlation coefficient of 0.989 as compared to other parameters (BPD = 0.986, HC = 0.976, AC = 0.971, FL = 0.984).
Conclusions: Fetal kidney showed strongest linear correlation with clinical gestational age and it also demonstrated positive correlation with biparietal diameter, head circumference, abdominal circumference and femur length. Therefore fetal kidney length can be used as a reliable parameter for determination of gestational age.
Introduction: Biliary diseases such as cholelithiasis, cholecystitis, hepatitis, cirrhosis and pancreatitis are common in Nepal. Cholelithiasis was present in 8 percent of the emergency patients, second to acute appendicitis. Acute cholecysistitis was present in 25 percent of these patients. 1 The most common operation in a district hospital was cholecystectomy (31%]).2 Ultrasound plays an integral part in evaluation of biliary system. The aim of the study was also to determine whether the size of the CBD increases with age.
Introduction: Determination of fetal weight is important in all pregnancies. Accurate antenatal assessment of the fetal weight is essential for deciding the plan of management that will minimize the perinatal morbidity and mortality rate.
