Assessment of renal transplant dysfunction by doppler sonography: A systematic review and meta-analysis.

Background: Doppler sonography parameters, particularly the resistive index (RI), have been identified as an essential tool for assessing renal transplant dysfunction (RTD). However, there is some ambiguity in the findings of previous research studies on this matter. Therefore, the objective of our study is to examine the relationship between changes in RI subsequent to RTD.

Percutaneous embolization of renal pseudoaneurysms: A retrospective study.

Introduction: We evaluated the efficacy of the mixture of autologous blood and a hemostatic agent, oxidized regenerative cellulose (ORC), as an alternative material for ultrasound (US)-guided percutaneous embolization of renal pseudoaneurysm (PA).

Methods: In this retrospective study, consecutive patients diagnosed with renal PA were included. The exclusion criteria were: PA of the main renal artery, tiny PA not visualized on the colour doppler ultrasonography, PA more than 3 cm in max diameter or extracapsular PA with the possibility of massive bleeding, and patients with a history of coagulation disorders.

Association of CT Scan Parameters with the Risk of Renal Angiomyolipoma Rupture; a Brief Report.

Introduction: Rupture of renal angiomyolipoma (AML) is an emergency and life-threatening complication. This study aimed to evaluate the association of computed tomography (CT) scan parameters with the risk of rupture in renal AMLs.

Methods: In this retrospective cross-sectional study, patients who were referred to a referral university hospital with diagnosis of AML, between 2007 and 2019, were included.

Evaluation of the role of reflux pattern in Color Doppler Ultrasound on spermogram improvement after varicocelectomy.

Purpose: Many attempts are being made to find an association between varicocele characteristics and sperm parameters. In this study, we investigated the association between a newly introduced varicocele reflux grading pattern and sperm parameters, as well as its effect on spermogram improvement after varicocelectomy.

Methods: In a prospective study, 73 patients with a clinical single-sided varicocele who underwent corrective varicocelectomy were included.

Recent advances of therapeutic targets based on the molecular signature in breast cancer: genetic mutations and implications for current treatment paradigms.

Breast cancer is the most common malignancy in women all over the world. Genetic background of women contributes to her risk of having breast cancer. Certain inherited DNA mutations can dramatically increase the risk of developing certain cancers and are responsible for many of the cancers that run in some families.

Color Doppler sonography of the aortic isthmus in intrauterine growth-restricted fetuses and normal fetuses.

Intrauterine growth restriction is associated with a significant increase in morbidity and perinatal mortality, and increases the likelihood of fetal death, asphyxia, meconium aspiration, hypoglycemia, and neonatal hypothermia. The aim of this study was to determine aortic isthmus flow difference by using color doppler sonography in Intrauterine growth restriction and normal fetuses. The data presented were obtained from 30 mothers, who referred to the radiology department of Akbarabadi Hospital of Tehran with a diagnosis of intrauterine growth restriction.
