Still, mortality usually occurs in patients with comorbidities, such as chronic kidney disease (CKD), which accounts for over 20% of mortalities, morbid obesity, immunosuppression, diabetes mellitus, hypertension, and cancer. Also, the incidence of acute kidney failure was reported to be 5-10% in outpatient series and up to 50% in patients that need to be admitted to the intensive care unit. It is important to know that acute kidney injury (AKI) is associated with increased mortality, so this essay will review possible mechanisms that result in AKI. Based on the multifactorial mechanism of AKI, we should have considered probable causes of AKI and acted stepwise to tackle these mechanisms and improve the ultimate prognosis of patients. Although most of the measures are supportive, in some patients, such as severely ill cases, cytokine storm may be attributed to the severity of symptoms, so immunomodulatory treatments could decrease AKI and mortality. Among hypotheses that propose AKI, a virus's pre-renal and direct renal involvement are discussed in detail.Urology Research Center, Tehran University of Medical SciencesTranslational Research in Urology2717-042X2320200815Case Report: Rare Bladder Injury During Cesarean Section798211951510.22034/tru.2020.256568.1041ENAli TavoosianDepartment of Urology, Tehran University of Medical Sciences, Tehran, Iran0000-0003-0311-3185Akram MirzaeiUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0003-2219-999XMohammad AslzareDepartment of Urology, Mashhad University of Medical Sciences, Mashhad, IranJournal Article20200612<strong>Introduction</strong><br />Bladder injury is an urgent emergency case requiring urgent treatment in order to restore the normal function of the urinary system.<br /><strong>Case presentation</strong><br />Here we present a 38-year-old woman with a history of primary infertility with a twin pregnancy following in vitro fertilization (IVF). Because of the high adhesion, the anterior wall of the bladder cut transversely instead of the anterior wall of the uterus. In this case of twin cesarean section, the anterior wall, posterior wall, and uterine wall were opened. The twins were removed from the bladder by two incisions and then the posterior and anterior wall of the bladder were repaired by an expert urologist as well as the uterus followed by medication by anticholinergic and antibiotics. This case report emphasizes the essential roles of bladder emergency repair in restoring the normal function of the urinary system.<br /><strong>Conclusions</strong><br />Bladder injury is the most common complication during gyneco-genital surgery. Most of this damage is intraperitoneal that needs repair during the surgery and prolonged bladder catheterization.Urology Research Center, Tehran University of Medical SciencesTranslational Research in Urology2717-042X2320200816Homeostatic Efficacy of Microporous Polysaccharide Hemosphere in Post-Operative Complications Reduction of Tubeless Percutaneous Nephrolithotomy838811954910.22034/tru.2020.257231.1047ENSeyed Mohammad Kazem AghamirUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0003-1611-0362Mahdi Ramezani-binabajUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0002-0770-0654Fatemeh KhatamiUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0002-6311-1336Behrooz FatahiDepartment of Urology, Lorestan University of Medical Sciences, Lorestan, Iran0000-0001-7674-036Journal Article20200615<strong>Introduction</strong><br />Current hemostatic agents are needed to reduce bleeding and transfusion during several surgery processes. Plant-based absorbable surgical hemostatic agents (microporous polysaccharide hemospheres) are proposed for use in surgical wound sites as an absorbable hemostat and in this study, we checked its efficacy.<br /><strong>Methods</strong><br />This study was run under the Tehran University of Medical Science Ethics Committee observation based on the clinical trial registry criteria (IRCT20190624043991N1). Total numbers of 42 percutaneous nephrolithotomies (PCNL) patients were enrolled, 21 cases hemostatic powder and 21 controls. Hemostatic powder pumped into Amplatz sheath before its extraction.<br /><strong>Results</strong><br />The mean age of the case and control groups was 42.1±19.5, and 42.1±18.5 years, respectively. The median stone size was 11.3±1.85cm. Overall, the differences between sex, age, stone size, and location were not statistically significant in the two groups (p-value˃0.05). Serum hemoglobin reduction following PCNL was significant in both groups compared to the serum level before surgery (p-value<0.001). However, the difference was not significant between case and control groups postoperatively (p-value=0.727). Yet, postoperative serum creatinine reduction was not significantly different between the two groups compared to preoperative serum levels (p-value>0.05).<br /><strong>Conclusions</strong><br />The present study showed that microporous polysaccharide hemosphere (MPH) did not affect bleeding reduction, hemoglobin decline, and postoperative blood transfusion, and hospital stay.Urology Research Center, Tehran University of Medical SciencesTranslational Research in Urology2717-042X2320200818Complete Renal Duplication with Dysplastic Lower Moiety: A Case Report899211968210.22034/TRU.2020.245632.1029ENFateme GuitynavardUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0002-7664-5329Behrooz FatahiDepartment of Urology, Lorestan University of Medical Sciences, Lorestan, Iran0000-0001-7674-036Rahil MashhadiUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0003-1788-5282Vahid AbediUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0003-4084-9263Alireza GorjiUrology Research Center, Tehran University of Medical Sciences, Tehran, IranMohammad Hatef KhorramiDepartment of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran0000-0003-1246-6345Journal Article20200628<strong>Introduction</strong><br />Ureter duplication is a common anomaly of the urinary tract in which both ureters drain one kidney. In bipolar renal duplication, the Meyer-Weigert-Rule describes the duplex ureters draining pattern. Owing to obstruction, the upper pole is usually seen as dysplastic, while the lower pole is associated with vesicoureteral reflux.<br /><strong>Case presentation</strong><br />Herein, we report a rare case of renal duplication in which the lower moiety is dysplastic. A 30-year-old woman with a right single kidney with atrophic and dysfunction without secretions.<br /><strong>Conclusions</strong><br />Radiologists and urologists should always be aware because if the lower moiety is obstructive, this newly implemented variation can require individualized care.<br /><strong> </strong>Urology Research Center, Tehran University of Medical SciencesTranslational Research in Urology2717-042X2320200822Circulating Tumor Cells as a Novel Prostate Cancer Diagnostic Tool939512019110.22034/tru.2020.260779.1055ENFatemeh KhatamiUrology Research Center, Tehran University of Medical Sciences, Tehran, Iran0000-0002-6311-1336Mandana HasanzadMedical Genomics Research Center, Tehran Medical Sciences Branch, Islamic Azad University, Tehran, IranJournal Article20200701The current screening test for prostate cancer (PCa) has the weak point of a high false-negative rate and a low true positive rate. There is an extreme need for a new and accurate testing system. Circulating Tumor Cells (CTCs) as the main liquid biopsy components provide excellent biomarkers for early diagnosis of PCa, prognosis, recurrence risk, and treatment efficacy. These tumor cells can get the release of tumor and freely circulate in the patient’s body fluids and easily are traceable to answer the presence of the tumor more than its stage. The new gifted ISET®-CTC Test is a simple blood test with high sensitivity and specificity for the detection of CTC in PCa. As a novel idea, it is a challengeable point nowadays that it needs further studies.

The molecular structure and genome of this virus are identical to SARA-CoV and for an unknown reason, it is highly transmittable. The spike protein is responsible to attach to the host cell and viral single-stranded RNA (ssRNA) entrance to the cells. Upon binding of the Spike proteins to the host cell ACE2 receptor and merging with the membrane, COVID-19 ssRNA goes to the host cells. The viral RNAs are recognized as the foreign element by TLR3, TLR7, TLR8, and TLR9 in the host cell. The viral genome receptor retinoic-acid inducible, cytosolic receptor melanoma differentiation-associated gene and nucleotidyltransferase cyclic GMP-AMP synthase (cGAS) is in charge of viral RNA representation in the cytoplasm. Now there is no targeted therapeutics with high efficacies for the treatment of Covid 19 disease. More than usual medication some interfering RNA molecules are under debate. The reason for being high transmission of COVID-19 is not recognized. This virus pandemic is now all over the world.

Chimeric antigen receptor T cells (CAR-Tcell), are T cells are genetically engineered T cells that produce an artificial T-cell receptor for use in immunotherapy. Chimeric antigen receptors are receptor proteins that have been engineered to give T cells the new ability to target a specific protein Its effect is mostly achieved using activating the immune system; the same mechanism proposed likely for chimeric antigen receptor (CAR) T cells. Hence CAR-T cell therapy could be considered for bladder cancer treatment.
