The term "obstructive uropathy" refers to the complex structural and functional changes following the interruption of normal urinary runoff, which can occur at every level of the urinary tract. Depending on its origin, duration and severity, urinary tract obstructions can be acute or chronic, mono or bilateral, partial or complete. The obstruction can be localized or extended to the entire pielo-caliceal system and/or homolateral urethra. Read More

The influence of atrial fibrillation on the mortality of incident ESRD patients undergoing maintenance hemodialysis.

PLoS One 2020 30;15(1):e0228405. Epub 2020 Jan 30.

Division of Nephrology, Department of Internal Medicine, Wan Fang Hospital, Taipei Medical University, Taipei, Taiwan.

Background: Atrial fibrillation (AF) is highly prevalent, occurring in 1%-2% of the adult population, increasing the risk of stroke, and resulting in considerable healthcare costs. While stroke is a major complication of AF, end-stage renal disease (ESRD) patients also have a high risk of stroke, suggesting that AF is a possible risk factor for mortality of ESRD patients. However, whether the existence of AF at the initiation of hemodialysis predicts higher mortality risk of incident ESRD patients remains to be defined. Read More

Urogenital tuberculosis - epidemiology, pathogenesis and clinical features.

Nat Rev Urol 2019 10 23;16(10):573-598. Epub 2019 Sep 23.

Department of Clinical Microbiology, University College London Hospitals NHS Foundation Trust, London, UK.

Tuberculosis (TB) is the most common cause of death from infectious disease worldwide. A substantial proportion of patients presenting with extrapulmonary TB have urogenital TB (UG-TB), which can easily be overlooked owing to non-specific symptoms, chronic and cryptic protean clinical manifestations, and lack of clinician awareness of the possibility of TB. Delay in diagnosis results in disease progression, irreversible tissue and organ damage and chronic renal failure. Read More

J Nephrol 2018 Dec 6;31(6):863-879. Epub 2018 Sep 6.

Sant'Anna School of Advanced Studies, Department of Internal Medicine, University of Pisa, Pisa, Italy.

Chronic kidney disease (CKD) includes all clinical features and complications during the progression of various kidney conditions towards end-stage renal disease (ESRD). These conditions include immune and inflammatory disease such as: primary and hepatitis C virus (HCV)-related glomerulonephritis; infectious disease such as pyelonephritis with or without reflux and tuberculosis; vascular disease such as chronic ischemic nephropathy; hereditary and congenital disease such as polycystic disease and congenital cystic dysplasia; metabolic disease including diabetes and hyperuricemia; and systemic disease (collagen disease, vasculitis, myeloma). During the progression of CKD, ultrasound imaging and color Doppler imaging (US-CDI) can differentiate the etiology of the renal damage in only 50-70% of cases. Read More

Int J Surg Pathol 2017 Oct 14;25(7):652-658. Epub 2017 Jun 14.

1 University of Iowa Hospitals and Clinics, Iowa City, IA, USA.

Background: Acute kidney injury (AKI) often manifests in patients with liver disease because of a prerenal cause and presents as acute tubular necrosis or hepatorenal syndrome. Distinguishing between these entities is important for prognosis and treatment. Some patients may develop AKI related to their underlying liver disease: for example, membranoproliferative glomerulonephritis or IgA nephropathy. Read More

Vancomycin-Associated Cast Nephropathy.

J Am Soc Nephrol 2017 Jun 12;28(6):1723-1728. Epub 2017 Jan 12.

Urgences Néphrologiques et Transplantation rénale, Hôpital Tenon, Assistance Publique - Hôpitaux de Paris, Paris, France;

Vancomycin is a widely prescribed antibiotic, but the exact nature of vancomycin-associated nephrotoxicity is unclear, in particular when considering the frequent coadministration of aminoglycosides. We describe here the initial case of a 56-year-old woman with normal renal function developing unexplained ARF without hypovolemia after administration of vancomycin without coadministration of aminoglycosides. Studying the patient's renal biopsy specimen, we ascertained that obstructive tubular casts composed of noncrystal nanospheric vancomycin aggregates entangled with uromodulin explained the vancomycin-associated ARF.

Clinical Characterization and Treatment Patterns for the Frequent Exacerbator Phenotype in Chronic Obstructive Pulmonary Disease with Severe or Very Severe Airflow Limitation.

COPD 2017 02 8;14(1):15-22. Epub 2016 Nov 8.

e Unità Operativa di Pneumologia , Azienda Ospedaliero-Universitaria Policlinico Vittorio Emanuele , Catania , Italy.

Chronic obstructive pulmonary disease (COPD) patients experiencing several episodes of acute clinical derangement suffer from increased morbidity, mortality, and accelerated decline in lung function. Nevertheless, the relationship between co-morbidity profile and exacerbation rates in the frequent exacerbator phenotype is poorly characterized, and evidence-based management guidelines are lacking. We sought to evaluate the co-morbidity profile and treatment patterns of "frequent exacerbators" with severe or very severe airflow limitation. Read More

An overview of kidney stone imaging techniques.

Nat Rev Urol 2016 11 31;13(11):654-662. Epub 2016 Aug 31.

Department of Urology, University of Washington School of Medicine, 1959 NE Pacific Street, Box 356510, Seattle, Washington 98195, USA.

Kidney stone imaging is an important diagnostic tool and initial step in deciding which therapeutic options to use for the management of kidney stones. Guidelines provided by the American College of Radiology, American Urological Association, and European Association of Urology differ regarding the optimal initial imaging modality to use to evaluate patients with suspected obstructive nephrolithiasis. Noncontrast CT of the abdomen and pelvis consistently provides the most accurate diagnosis but also exposes patients to ionizing radiation. Read More
