CT urogram: a pictorial essay Abraham Noorbakhsh1 · Lejla Aganovic1,2 · Noushin Vahdat1,2 · Soudabeh Fazeli1 · Romy Chung1 · Fiona Cassidy1,2 Published online: 18 June 2019 © This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2019 Abstract Purpose The aim of this pictorial essay is to demonstrate several cases where the diagnosis would have been difcult or impossible without the excretory phase image of CT urography. Methods A brief discussion of CT urography technique and dose reduction is followed by several cases illustrating the utility of CT urography. Results CT urography has become the primary imaging modality for evaluation of hematuria, as well as in the staging and surveillance of urinary tract malignancies. CT urography includes a non-contrast phase and contrast-enhanced nephrographic and excretory (delayed) phases. While the three phases add to the diagnostic ability of CT urography, it also adds potential patient radiation dose. Several techniques including automatic exposure control, iterative reconstruction algorithms, higher noise tolerance, and split-bolus have been successfully used to mitigate dose. The excretory phase is timed such that the excreted contrast opacifes the urinary collecting system and allows for greater detection of flling defects or other abnormali- ties. Sixteen cases illustrating the utility of excretory phase imaging are reviewed. Conclusions Excretory phase imaging of CT urography can be an essential tool for detecting and appropriately characterizing urinary tract malignancies, renal papillary and medullary abnormalities, CT radiolucent stones, congenital abnormalities, certain chronic infammatory conditions, and perinephric collections.

Pathogenic variants in the genes encoding these proteins impair this function and have consequences on the whole organism. Establishing a genetic diagnosis in patients with renal tubular dysfunction is a challenging task given the genetic and phenotypic heterogeneity, functional characteristics of the genes involved and the number of yet unknown causes. Part of these difficulties can be overcome by gathering large patient cohorts and applying high-throughput sequencing techniques combined with experimental work to prove functional impact. This approach has led to the identification of a number of genes but also generated controversies about proper interpretation of variants. In this article, we will highlight these challenges and controversies. Keywords: inherited tubulopathies; next generation sequencing; genetic heterogeneity; variant classification. 1. Introduction Mutations in genes that encode transporter proteins in the renal tubule alter kidney capacity to maintain homeostasis and cause diseases recognized under the generic name of inherited tubulopathies.

  • Autosomal Dominant Medullary Cystic Kidney Disease (ADMCKD)
    Autosomal Dominant Medullary Cystic Kidney Disease (ADMCKD) Author: Doctor Antonio Amoroso1 Creation Date: June 2001 Scientific Editor: Professor Francesco Scolari 1Servizio Genetica e Cattedra di Genetica, Istituto per l'infanzia burlo garofolo, Via dell'Istria 65/1, 34137 Trieste, Italy. [email protected] Abstract Keywords Disease name Synonyms Diagnostic criteria Differential diagnosis Prevalence Clinical description Management Etiology Genetic counseling References Abstract Autosomal dominant medullary cystic kidney disease (ADMCKD) belongs, together with nephronophthisis (NPH), to a heterogeneous group of inherited tubulo-interstitial nephritis, termed NPH-MCKD complex. The disorder, usually first seen clinically at an average age of 28 years, is characterized by structural defects in the renal tubules, leading to a reduction of the urine–concentrating ability and decreased sodium conservation. Clinical onset and course of ADMCKD are insidious. The first sign is reduced urine– concentrating ability. Clinical symptoms appear when the urinary concentrating ability is markedly reduced, producing polyuria. Later in the course, the clinical findings reflect the progressive renal insufficiency (anemia, metabolic acidosis and uremic symptoms). End-stage renal disease typically occurs in the third-fifth decade of life or even later. The pathogenesis of ADMCKD is still obscure and how the underlying genetic abnormality leads to renal disease is unknown. ADMCKD is considered to be a rare disease. Until 2000, 55 affected families had been described. There is no specific therapy for ADMCKD other than correction of water and electrolyte imbalances that may occur. Dialysis followed by renal transplantation is the preferred approach for end-stage renal failure. Keywords Autosomal dominant medullary cystic disease, medullary cysts, nephronophthisis, tubulo-interstitial nephritis Disease name Diagnostic criteria Autosomal dominant medullary cystic kidney The renal presentation of MCKD is relatively disease (ADMCKD) non-specific.

It is a potentially self-limited disease. The aim of this study was to evaluate the clinical course and significant factors in children with primary VUR. The medical charts of 125 infants and children (27.2 % males, 72.8% females) with all grades of primary VUR were retrospectively reviewed. Mean age at diagnosis was 22.3±22.9 months. 52% of patients had bilateral VUR. Mild reflux (Grade I, II) was the most common initial grade. 53.6% of patients achieved spontaneous resolution. 30.1% of patients had decreased renal function on initial DMSA renal scan, significantly in males and severe VUR. Reflux nephropathy occurred in 17.6% of patients, especially in renal damage and male sex. No significant association was observed between recurrent urinary tract infection with the severity of VUR, and the presence of renal damage at admission. Age at diagnosis, gender, grade, laterality, the absence of recurrent urinary tract infection and renal damage had a significant correlation between spontaneous VUR resolution.

Since angiotensin converting cantly from the ramipril group, except for higher Hcy enzyme inhibitors (ACEI) have been shown to improve levels in the latter. Administration of ramipril resulted in the antioxidative defence, we investigated, in patients a drop in blood pressure and proteinuria, while creati- with nondiabetic nephropathy, the short-term effect of nine clearance remained the same. The fluorescent the ACEI ramipril on parameters of oxidative stress, AGEs exhibited a mild but significant decline, yet CML such as advanced glycation end products (AGEs), concentration was unchanged. The AOPP and malon- advanced oxidation protein products (AOPPs), homo- dialdehyde concentrations decreased, while a small rise cysteine (Hcy), and lipid peroxidation products. Ramipril in neopterin levels was evident after treatment. The (2.5–5.0 mg/day) was administered to 12 newly diag- mentioned parameters were not affected significantly in nosed patients for 2 months and data compared with a the conventionally treated patients. Evidence that rami- patient group under conventional therapy (diuretic/ pril administration results in a mild decline of fluores- b-blockers) and with age- and sex-matched healthy cent AGEs is herein presented for the first time.
