Role of Shear Wave Elastography for Assessment of Renal-Allograft Fibrosis and its Correlation With Histopathology.

Objectives: To investigate whether shear wave elastography (SWE) can accurately identify interstitial fibrosis and tubular atrophy (IFTA) in chronic renal allograft injury (CRAI) and whether it can differentiate between different grades of IFTA.

Materials And Methods: Prospective observational study on renal transplant recipients who presented with CRAI. Patient selection was done on the basis of clinical presentation, serum creatinine, and eGFR levels.

Assessment of Gastric Residual Volume with Ultrasound in Children at Fasting and after Oral Intake of Carbohydrate-Rich Fluid in the Preoperative Period.

Purpose: Despite standard preoperative fasting guidelines, children are subjected to prolonged fasting due to various reasons. This does not reduce gastric residual volume (GRV) further, instead causes hypoglycemia, hypovolemia, and unnecessary discomfort. We calculated the cross-sectional area (CSA) of antrum and GRV in children in fasting state and 2 h after intake of oral carbohydrate-rich fluid, using gastric ultrasound.

Direct Percutaneous Thrombolysis (DPT): A novel method of salvaging Thrombosed Native Arteriovenous Fistula.

Introduction: Thrombosed arteriovenous fistulas (AVFs) are either treated by thrombectomy or pharmaco-mechanical thrombolysis with or without percutaneous balloon angioplasty. In this study, we have described an effective and economical technique of salvaging these fistulae using a 20-22-gauge spinal needle and urokinase and have named it direct percutaneous thrombolysis (DPT).

Materials And Method: This prospective study comprised of 148 patients out of which 120 patients presented with AVF thrombosis and were divided into two groups; those with no obvious stenosis on ultrasound ( = 38) and second with venous stenosis ( = 82).

Aetiology, management, and outcome of lower respiratory tract infection in renal allograft recipients - A report from a tropical country.

Introduction: Lower respiratory tract infections (LRTIs) among renal transplant recipients (RTRs) are a significant cause of morbidity and mortality. This study aimed to analyse the aetiology, outcome, and risk factors associated with mortality.

Methods: We analysed baseline transplant characteristics, symptoms, hospital course, laboratory, serological and microbial results, and their association with the outcome of all RTRs between January 2011 and December 2019.

Role of Computed Tomography in Estimation of Residual Renal Function at One Year after Donor Nephrectomy: Comparison with Nuclear Scintigraphy.

Computed tomography (CT) is routinely used for preoperative anatomical evaluation of renal donors, but recent studies show that it may be useful as a predictor of renal function too. This study aimed to compare CT volumetry-attenuation-based glomerular filtration rate (GFR) with Tc99m-diethylene-triamine-pentaacetic acid (DTPA) renal scintigraphy GFR and predict post-donor nephrectomy renal function. This is a prospective study involving 39 renal donors at a tertiary care hospital in northern India from 2014 to 2017.

Endovascular Embolization in Problematic Hemodialysis Arteriovenous Fistulas: A Nonsurgical Technique.

Introduction: In the past, surgical techniques were considered gold standard practice for obliterating the accessory veins, reducing the flow across the high flowing arteriovenous fistulas (AVFs), or for closing the problematic hemodialysis AVFs. However, recently endovascular embolization has emerged as a safe and cost-effective alternative to these surgical techniques. In this study, technical and clinical success, and safety of endovascular embolization have been evaluated for accessory vein obliteration, flow reduction, and fistula closure in problematic AVFs using various embolizing agents.

Can we predict early renal impairment in pediatric cirrhosis?

Aims: Published literature on renal dysfunction (RD) in pediatric cirrhosis are limited. We aimed to detect early RD in cirrhotic children by renal resistive index (RI) and plasma aldosterone (PA). We evaluated the effects of large-volume paracentesis (LVP) and albumin infusion on the same.

Role of blood oxygen level-dependent magnetic resonance imaging in studying renal oxygenation changes in renal artery stenosis.

Aim: Primary objective of this study was to compare R2* value of the post-stenotic kidney with contralateral kidney, kidneys of essential hypertensive patients, and healthy subjects using blood oxygen level-dependent magnetic resonance imaging (BOLD MRI) technique. The secondary objective was to study the effect of severity of stenosis and viability of kidneys on R2* value.

Methods: We compared 4 groups of kidneys including 92 with renal artery stenosis, 37 normal contralateral kidneys of unilateral renal artery stenosis patients, 62 kidneys of essential hypertensive patients, and 40 kidneys of healthy controls using BOLD MRI.

Congenital renal arteriovenous malformation: a rare cause of visible haematuria.

We report a case of renal arteriovenous malformation (AVM) and describe its angioarchitecture and endovascular management. A 28-year-old male patient presented with visible painless haematuria. CT of the abdomen showed a right renal AVM.

Determination of split renal function in voluntary renal donors by multidetector computed tomography and nuclear renography: How well do they correlate?

Background: The use of computed tomography (CT) for estimation of split renal function (SRF) has been reported previously. However, most of these studies have small samples, and many do not account for the renal attenuation at CT.

Objective: The aim of this study was to compare multidetector computed tomography (MDCT) volumetry-attenuation-based SRF with that obtained via Tc99m-diethylenetriaminepentaacetic acid (DTPA) renal scintigraphy in voluntary renal donors.

Treatment of deep-seated palatal vascular malformations by bleomycin sclerotherapy.

Background: Vascular malformations of the head and neck are common. The management of these lesions is complex and challenging due to the high complication rate and recurrence following treatment. Palatal vascular malformations (PVMs) are infrequent and present as slow growing lesions in the palate with recurrent bleeding and pain.

Transjugular Versus Percutaneous Liver Biopsy in Children: Indication, Success, Yield, and Complications.

Background/objective: Percutaneous biopsy (PB) and transjugular liver biopsy (TJLB) are 2 main ways of obtaining liver tissue. We evaluated the indications, success rate, tissue yield, and complications of TJLB in comparison to PB in children.

Methods: Electronic records of children undergoing liver biopsy (LB) were reviewed.

Role of MRI in staging and surgical planning and its clinicopathological correlation in patients with renal cell carcinoma.

Background And Aims: Radiological evaluation of renal cell carcinoma (RCC) is used for non-invasive staging for better surgical planning. However, the correlation of radiological staging using magnetic resonance imaging (MRI) with histopathological findings has not been done so far. The aim of this study is to assess the role of MRI in pre-operative staging of RCC in patients undergoing radical nephrectomy and nephron sparing surgery (NSS) and correlate it with histopathological findings.

Diagnostic Performance of 6-Point Lung Ultrasound in ICU Patients: A Comparison with Chest X-Ray and CT Thorax.

Objective: To evaluate the diagnostic performance of a rapid bedside 6-point lung ultrasonography (LUS) performed by an intensive care unit (ICU) physician for detection of four common pathological conditions of the lung, such as alveolar consolidation, pleural effusion, interstitial syndrome and pneumothorax, in critically ill patients and its comparison with bedside chest X-ray (CXR) and high-resolution computed tomography (CT) scan of the thorax. Volume of pleural effusion measured by LUS and CT thorax was also compared.

Methods: This was a cross-sectional, observational study of 90 adult patients with an acute lung injury score of ≥1 admitted to the medical-surgical ICU.

Yolk Sac Tumor of Stomach: Case Report and Review of Literature.

Gastric yolk sac tumors (YSTs) are very rare. Only seven cases of pure YST of the stomach, with a median age of 65 years, and five cases of YST combined with adenocarcinoma have been reported. We report a 3-year-old boy who presented to us with recurrent episodes of melena and anemia of 2 months' duration.

Prognostic scoring systems and outcome of endovascular radiological intervention of chronic Budd-Chiari syndrome in children.

Background And Aim: Prognostic scoring systems (PSS) have not been validated in children with chronic Budd-Chiari syndrome (BCS). We aimed to analyse the long-term outcome of radiological intervention (RI) and validate the PSS in children.

Methods: Chronic BCS children were analysed in four subgroups: (i) SI: successful intervention (primary or secondary stent patency) (ii) PO: poor outcome (refractory stent block or requirement of liver transplantation), (iii) NU: naïve unintervened (awaiting RI) and (iv) DBI: died before intervention.
