Laparoscopic pyeloplasty practice patterns in Canada.

Can Urol Assoc J 2019 Jan 21. Epub 2019 Jan 21.

Division of Urology, Department of Surgery, The Ottawa Hospital and University of Ottawa, Ottawa, ON, Canada.

Introduction: Ureteropelvic junction obstruction (UPJO) is a condition characterized by partial or complete obstruction of urine transport from the renal pelvis to the ureter and can present with intermittent flank pain, recurrent urinary tract infections, renal stones, or renal dysfunction. While historically, open pyeloplasty was the gold standard for surgical management, laparoscopic methods to repair UPJO have largely taken over as the preferred approach for adolescent and adult patients. Despite near universal adoption of laparoscopic pyeloplasty among Canadian urologists, it remains a technically complex procedure and considerable variability exists in the procedural steps performed.

[Long-term monitoring of leukocyturia and bacteriuria after acute obstructive pyelonephritis].

Urologiia 2018 Oct(4):44-48

RostSMU of Minzdrav of Russia, Rostov on Don, Russia.

The generally accepted standard of antibiotic therapy aimed at causative agent does not exclude the risk of acute obstructive pyelonephritis (AOP) to become chronic after the end of antibiotic therapy, resulting in a high incidence of relapses. To assess the outcomes of the AOP, we undertook a prospective clinical trial. MATERIALS AND METHODS: The study comprised 51 consistently selected patients (12 men and 39 women) with AOP occurred as a result of unilateral ureteric calculus obstruction. Read More

[Factors predicting the development of urinary tract disorders in prostatic hyperplasia in elderly men].

Urologiia 2018 Dec(6):150-154

Department of Faculty Surgery with the course of Urology FGBOU VO Chita State Medical University, Chita, Russia.

The review article presents information from foreign and domestic authors on the relevance of studying the incidence of men with bening prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Complex urodynamic studies (CUDS) remains the most informative test of the degree of expression of LUTS and bladder outlet obstruction () caused by BPH. The difficulty in interpreting the results, the invasiveness and inaccessibility of CUDS in the routine practice of most medical institutions makes it necessary to perform relatively simpler and more accessible methods of research, which do not always objectively reflect the degree of urinary incontinence in older men.

Urologiia 2018 Dec(6):14-18

MBUZ Clinical and diagnostic Center Zdorovie, Rostov-on-Don, Russia.

Aim: Radical treatment of prostate cancer (PCa) is often associated with the development of urinary incontinence (UI). The etiology of UI after prostatectomy is multifactorial and can be caused by both urethral sphincter deficiency and bladder dysfunction. To date, there are no comparative studies of the development of UI in patients after either organ-preserving treatment or radical prostatectomy (RP). Read More

First-year profile of biomarkers for early detection of renal injury in infants with congenital urinary tract obstruction.

Pediatr Nephrol 2019 Jan 29. Epub 2019 Jan 29.

Pediatric Nephrology Unit, Department of Pediatrics, Instituto da Criança, Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, Av. Dr. Enéas Carvalho de Aguiar, 647, São Paulo, CEP: 05403-000, SP, Brazil.

Background: Diagnosis of renal function impairment and deterioration in congenital urinary tract obstruction (UTO) continues to be extremely challenging. Use of renal biomarkers in this setting may favor early renal injury detection, allowing for a reliable choice of optimal therapeutic options and prevention or minimization of definitive renal damage.

Methods: This longitudinal, prospective study analyzed the first-year profile of two serum renal biomarkers: creatinine (sCr) and cystatin C (sCyC); and six urinary renal biomarkers: neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), transforming growth factor beta-1 (TGF-β1), retinol-binding protein (RBP), cystatin C (uCyC), and microalbuminuria (μALB) in a cohort of 37 infants with UTO divided into three subgroups: 14/37 with unilateral hydro(uretero)nephrosis, 13/37 with bilateral hydro(uretero)nephrosis, and 10/37 patients with lower urinary tract obstruction (LUTO), compared with 24 healthy infants matched by gestational age and birth weight.

Neutral endopeptidase inhibitors blunt kidney fibrosis by reducing myofibroblast formation.

Clin Sci (Lond) 2019 Jan 22;133(2):239-252. Epub 2019 Jan 22.

Department of Internal Medicine (Nephrology) and the Einthoven Laboratory for Vascular and Regenerative Medicine, Leiden University Medical Center, Leiden, The Netherlands

Kidney fibrosis is the common pathophysiological mechanism in end-stage renal disease characterized by excessive accumulation of myofibroblast-derived extracellular matrix. Natriuretic peptides have been demonstrated to have cyclic guanosine monophosphate (cGMP)-dependent anti-fibrotic properties likely due to interference with pro-fibrotic tissue growth factor β (TGF-β) signaling. However, , natriuretic peptides are rapidly degraded by neutral endopeptidases (NEP). Read More

Urinary heat shock protein-72: A novel marker of acute kidney injury and chronic kidney disease in cats.

Vet J 2019 Jan 30;243:77-81. Epub 2018 Nov 30.

Koret School of Veterinary Medicine, Hebrew University of Jerusalem, P.O. Box 12, Rehovot, 761001, Israel.

Acute kidney injury (AKI) in cats is associated with high mortality, partially attributed to late recognition of the disease when using currently available markers. Feline chronic kidney disease (CKD) has a variable progression rate. This study aimed to evaluate the sensitivity and specificity of urinary heat shock protein-72 to urinary creatinine ratio (uHSP72:uCr) as a diagnostic and prognostic marker in feline AKI, and as a prognostic indicator in feline CKD.
