Scintigraphic findings in renal vein thrombosis (RVT) have been well described on studies performed with Tc-99m DPTA, Tc-99m glucoheptonate, and I-131 orthoiodohippurate. The authors could find no reports of RVT findings on Tc-99m mercaptoacetyltriglycine (MAG3) imaging. Tc-99m MAG3 renal scintigraphy in an infant with RVT because of Finnish-type congenital nephrotic syndrome is described. Correlative ultrasound and inferior vena cava venogram findings are presented.

Antegrade Ureteral Stenting in Pediatric Patients: Introducing a Novel Ureteral Morphological Classification and a New Perspective on Functional Success.

Interventional Radiology Department, Adana Dr. Turgut Noyan Application and Research Center, Başkent University, 01250 Adana, Turkey.
: The objective of the current research is to assess the benefits that come with antegrade ureteral stenting coupled with imaging techniques in children and also provide a new classification based on the ureter's morphological elements. : Between 2011 and 2024, 107 antegrade stent placement procedures performed in 71 pediatric patients aged 0-12 years who could not undergo retrograde double-J stent placement were retrospectively analyzed. According to the morphologic structure of the ureter, four categories were classified as normal, straight/slightly angled, S-shaped, and spiral-shaped.

Background: The study aimed at evaluating the role of thiol-disulphide balance parameters [native thiol (SH), total thiol (SH + SS), disulphide (SS), disulphide/native thiol ratio (% SS/SH), disulphide/total thiol ratio (% SS/Total Thiol) and native thiol/total thiol ratio (%SH/Total Thiol)], which are important oxidative stress markers in the congenital ureteropelvic junction (UPJ) stenosis, in the diagnosis of the disease, and its role in determining the need for surgery and follow-up.
Materials And Methods: This prospective study included 30 children diagnosed with congenital intrinsic ureteropelvic junction obstruction (UPJO) and a control group of 30 healthy children admitted to the pediatric clinic between January 2016 and February 2017. The children with UPJO underwent laparoscopic dismembered pyeloplasty.
[The Usefulness of MAG3 Diuretic Renography in the Evaluation of Stomal Obstruction after Cutaneous Ureterostomy].

Cutaneous ureterostomy (CU) is the most simple and safe method of all permanent urinary diversions, but is associated with a risk for stomal obstruction. It is important to appropriately manage hydronephrosis associated with CU. We evaluated the occurrence of stomal obstruction after CU by 99m Tcmercaptoacetyltriglycine (MAG3) diuretic renography three months after surgery.

Purpose: Our objective was to assess a deconvolution and denoising technique based on Legendre polynomials compared to matrix deconvolution on dynamic F-FDG renography of healthy patients.
Method: The study was carried out and compared to the data of 24 healthy patients from a published study who underwent examinations with Tc-MAG3 planar scintigraphy and F-FDG PET/MRI. Due to corruption issues in some data used in the published article, post-publication measurements were provided.
