Obstructive urosepsis secondary to ureteric herniation into the sciatic foramen.

BMJ Case Rep 2018 Sep 27;2018. Epub 2018 Sep 27.

Department of Urology, St George's Hospital, London, UK.

A 65-year-old female patient presented with a 2-day history of worsening right-sided abdominal pain and clinical signs of sepsis, on the background of a recent admission for pancolitis. Imaging revealed right ureteric herniation through the sciatic foramen with subsequent hydroureteronephrosis and radiological signs of severe pyelonephritis. The patient underwent emergency decompression with a percutaneous nephrostomy, followed by insertion of an antegrade stent to correct the ureteric hernia once the sepsis was appropriately treated.

BMJ Case Rep 2018 Jun 4;2018. Epub 2018 Jun 4.

Department of Medicine, Jersey Shore University Medical Center, Neptune City, New Jersey, USA.

Duplication of the inferior vena cava (DIVC) is an uncommon embryological anatomic phenomenon.We report a 63-year-old woman with extensive right leg deep vein thrombosis who required an IVC filter due to contraindications for anticoagulation, but was found to have DIVC which required the placement of two IVC filters with good result. This report will review and summarise past reports of DIVC management to provide a guide for future clinicians, and review the embryological development, diagnosis and IVC filter placement options as they are based on the type of anatomic malformation encountered.

Obstructive uropathy as initial presentation of genitourinary tuberculosis and masquerading as a postsurgical complication.

BMJ Case Rep 2017 Oct 15;2017. Epub 2017 Oct 15.

Department of Internal Medicine, University Teaching Hospital of Kigali, Kigali, Rwanda.

A 46-year-old woman who had a recent total abdominal hysterectomy presented with a 1 month history of lower abdominal pain, 1 week of nausea and vomiting as well as decreased urinary output preceded by a year of significant unintentional weight loss. On renal imaging, she was found to have bilateral hydronephrosis and hydroureters in the setting of bilateral distal ureteric obstruction complicated with acute kidney injury and severe hyperkalaemia requiring haemodialysis. The initial concern was for ureteric injury, a known complication of abdominal hysterectomy procedures, however, a urological intervention, performed 9 months later to relieve the ureteric obstruction, revealed purulent material within the left ureter that was smear positive for acid fast bacilli.

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.

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

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

Department of Radiology, "Luigi Sacco" University Hospital, Via G.B. Grassi 74, 20157, Milan, Italy.

Complicated urinary tract infections (C-UTIs) are those associated with structural or functional genitourinary abnormalities or with conditions that impair the host defence mechanisms, leading to an increased risk of acquiring infection or failing therapy. C-UTIs occur in patients with risk factors such as neurogenic dysfunction, bladder outlet obstruction, obstructive uropathy, bladder catheterisation, urologic instrumentation or indwelling stent, urinary tract post-surgical modifications, chemotherapy- or radiation-induced damage, renal impairment, diabetes and immunodeficiency.Multidetector CT and MRI allow comprehensive investigation of C-UTIs and systemic infection from an unknown source.

Endovascular Repair of Ruptured Abdominal Aortic Aneurysm Is Associated with Lower Incidence of Post-operative Acute Renal Failure.

Ann Vasc Surg 2016 Aug 26;35:147-55. Epub 2016 May 26.

Division of Vascular Surgery, Penn State Heart and Vascular Institute, Pennsylvania State University College of Medicine, Hershey, PA.

Background: Acute renal failure (ARF) after surgical treatment of ruptured abdominal aortic aneurysm (AAA) is an independent predictor of post-operative mortality. Open repair for ruptured AAA has been the gold standard treatment; however, there has been a recent trend in increased utilization of endovascular repair (EVAR) for treatment of ruptured AAA. The purpose of this study was to retrospectively review and compare the incidence of ARF among patients treated with open versus endovascular repair of ruptured AAA. Read More

[Urosepsis. Update on diagnosis and treatment].

Urologe A 2016 Apr;55(4):454-9

Klinik für Urologie, Kinderurologie und Andrologie, Justus-Liebig-Universität, Gießen, Rudolf-Buchheim Str. 7, 35392, Gießen, Deutschland.

Background: Sepsis is an acute systemic response to the presence of bacteria and bacterial components in the macroorganism, and urosepsis is defined as sepsis caused by an infection in the urogenital tract. The urogenital tract is considered to be responsible for about 30 % of the cases of septic processes, whereby obstructive uropathy is causative in about 80 % of these cases. Sepsis manifests as an initially predominant proinflammatory response by widespread release of inflammatory mediators as a result of activation of cells responsive to infectious components such as bacterial toxins, which is then accompanied by a counter-regulatory anti-inflammatory response.

[How to manage a pyelocalyceal dilatation?].

Rev Med Suisse 2015 Dec;11(497):2293-4, 2296-7

Due to its length and its small diameter, the ureter is exposed to a high obstructive risk which may be ascribed to extremely variable pathologies. Because of a remarkably active peristalsis, the clinical consequence is acute if the obstacle suddenly settles. The radiological sign of appeal is the pyelocalyceal dilatation, which is widely listed in the Western medical system, in consideration of the abundance of the practiced imaging. Read More

Prognostic factors and biomarkers of congenital obstructive nephropathy.

Pediatr Nephrol 2016 09 14;31(9):1411-20. Epub 2015 Dec 14.

Department of Pediatrics, University of Virginia School of Medicine, Charlottesville, VA, USA.

Congenital obstructive nephropathy (CON) is the leading cause of chronic kidney disease (CKD) in children. Anomalies of the urinary tract are often associated with abnormal nephrogenesis, which is compounded by obstructive injury and by maternal risk factors associated with low birth weight. Currently available fetal and postnatal imaging and analytes of amniotic fluid, urine, or blood lack predictive value. Read More

Unilateral ureteral obstruction induces DNA repair by APE1.

Am J Physiol Renal Physiol 2016 04 25;310(8):F763-F776. Epub 2015 Nov 25.

Department of Clinical Medicine, Aarhus University Hospital, Aarhus, Denmark;

Ureteral obstruction is associated with oxidative stress and the development of fibrosis of the kidney parenchyma. Apurinic/apyrimidinic endonuclease (APE1) is an essential DNA repair enzyme for repair of oxidative DNA lesions and regulates several transcription factors. The aim of the present study was to investigate whether APE1 is regulated by acute (24 h) and chronic (7 days) unilateral ureteral obstruction (UUO). Read More

Authors:
O O Buchok

Klin Khir 2015 May(5):70-2

Renal function was studied, using radionuclide renography, in 142 patients, suffering acute obstructive pyelonephritis, in 73 of whom transcutaneous nephrostomy was applied and in 69--the ureter's stenting, for the urine passage restoration. The investigation was peformed in 1 month and 1 year after miniinvasive treatment. After comparison of the investigation results there was established, that after transcutaneous nephrostomy, using miniinvasive technologies, the affected kidney's functional inhibition was trustworthy less, than after stenting.

Is there an advantage in performing a combined examination: diuretic renal scintigraphy and low dose computed tomography compared to the separate use of these methods in urolithiasis.

Hell J Nucl Med 2015 May-Aug;18(2):90-2. Epub 2015 Jul 20.

Clinic of Nuclear Medicine,University Hospital Alexandrovska, Medical University, Zdrave str., No 2, 1431, Sofia, Bulgaria.

Ultrasonography (US), radiography of the kidneys, ureters and bladder (RKUB), intravenous urography (IVU) and especially non-enchanced CT are well established diagnostic modalities in screening patients with urolithiasis, while not always fully diagnostic especially when obstructive uropathy or calculous pyelonephritis are present . Diuretic renal scintigraphy (DRS) can determine obstruction, may differentiate between complete or partial, acute or chronic obstruction, but can not specify the cause and often the location of obstruction. The imaging protocol, including DRS with technetium-99m-mercaptylacetyltriglycine ((99m)Tc-MAG3) and single photon emission tomography/computed tomography (SPET/CT) of the kidneys, ureters, and urinary bladder allows for both functional and morphological information, visualization of renal stones and possible renal complications.

Cyclooxygenase type 2 (COX-2) plays a predominant role in the progression of kidney injury in obstructive nephropathy. The aim of this study was to test the efficacy of chitosan/small interfering RNA (siRNA) nanoparticles to knockdown COX-2 specifically in macrophages to prevent kidney injury induced by unilateral ureteral obstruction (UUO). Using optical imaging techniques and confocal microscopy, we demonstrated that chitosan/siRNA nanoparticles accumulated in macrophages in the obstructed kidney. Read More

Blood oxygenation level-dependent MRI for assessment of renal oxygenation.

Int J Nephrol Renovasc Dis 2014 21;7:421-35. Epub 2014 Nov 21.

Renal Division, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, NY, USA.

Blood oxygen level-dependent magnetic resonance imaging (BOLD MRI) has recently emerged as an important noninvasive technique to assess intrarenal oxygenation under physiologic and pathophysiologic conditions. Although this tool represents a major addition to our armamentarium of methodologies to investigate the role of hypoxia in the pathogenesis of acute kidney injury and progressive chronic kidney disease, numerous technical limitations confound interpretation of data derived from this approach. BOLD MRI has been utilized to assess intrarenal oxygenation in numerous experimental models of kidney disease and in human subjects with diabetic and nondiabetic chronic kidney disease, acute kidney injury, renal allograft rejection, contrast-associated nephropathy, and obstructive uropathy.

Prevalence of renal artery disease and its prognostic significance in patients undergoing coronary bypass grafting.

Am J Cardiol 2014 Oct 24;114(7):1029-34. Epub 2014 Jul 24.

Inserm U1094, School of Medicine, University of Limoges, Limoges, France; Department of Thoracic & Cardiovascular Surgery and Angiology, Dupuytren University Hospital, Limoges, France.

Several studies demonstrated the prognostic importance of renal failure and peripheral artery disease in patients undergoing coronary artery bypass grafting (CABG), but data regarding the prognostic value of renal artery disease in this context are scarce. We aimed to study the prevalence and prognostic value of renal artery disease in patients undergoing CABG. We assessed by duplex ultrasound the renal arteries of 429 consecutive patients who underwent CABG, of whom 401 had satisfactory imaging quality to detect >60% renal artery stenosis (RAS) and/or an elevated resistive index (ERI>0.
