Renal histologic changes in congenital ureteropelvic junction obstruction (UPJO), although well documented, are sparsely studied in children. This study aims to establish a histological grading depending on the glomerular and tubulo-interstitial changes in hydronephrotic kidneys and determine correlation with age at surgery and impact on function post-pyeloplasty. A renal cortical wedge biopsy was obtained after pyeloplasty and histological changes were graded from 1 to 4.

Background: Hydronephrosis developing at the ureteropelvic junction due to obstruction poses clinical challenges as it has the potential to cause renal damage.
Aims: This study aims to evaluate how well machine learning models such, as XGBClassifier and Logistic Regression can be used to predict the need for treatment in patients, with hydronephrosis resulting from ureteropelvic junction obstruction.
Methods: Hydronephrosis was diagnosed in the medical records of patients from January 2015 to December 2020.

The aim of this study was to assess the efficacy of GFR measured using ROI from ultrasound technique in diuretic renography for evaluating postoperative outcomes in infants under one year old with congenital hydronephrosis. A retrospective analysis was conducted on thirty infants who underwent abdominal ultrasound and diuretic renography before and after surgery, obtaining preoperative and postoperative gGFRs and uGFRs (measured using ROI from ultrasound technique) determined using the Gates method and ultrasonic-assisted drawing ROI technique, respectively. A comparative study was performed on total GFR as well as individual kidney GFR before and after intervention.

Article Synopsis
- Primary mucinous adenocarcinomas of the kidney are rare and their origins are unclear, with theories including chronic irritation and kidney maldevelopment.
- Two cases are presented: one involving a 50-year-old male with a duplex collecting system who had invasive mucinous carcinoma, and another case with a 53-year-old male who had a horseshoe kidney and recurrent mucinous adenocarcinoma after previous surgery.
- Both cases highlight the association between mucinous adenocarcinomas and kidney anomalies, emphasizing the importance of histopathology for diagnosis.
