Obstructive Pyelonephritis Secondary to Ureteral Compression by an Intra‐Abdominal Desmoid Tumor in Familial Adenomatous Polyposis: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT In patients with familial adenomatous polyposis, intra‐abdominal desmoid tumors should be recognized as a rare but important cause of ureteral obstruction and obstructive pyelonephritis. Prompt cross‐sectional imaging, early recognition, and multidisciplinary management are essential for preserving renal function, treating infection, and ...

Measurable Changes in Hydronephrosis During Pregnancy Induced by Positional Changes: Ultrasonic Assessment and its Diagnostic Implication

Urology Journal, 2005
Introduction: Unilateral or bilateral dilation of the ureters occurs commonly during pregnancy. Ultrasonography is a suitable diagnostic method for hydronephrosis; however, it cannot differentiate obstructive from nonobstructive hydronephrosis.

Feasibility of Imaging the Uvula at the Midtrimester Anomaly Ultrasound

Journal of Ultrasound in Medicine, Volume 45, Issue 8, Page 1707-1714, August 2026.
Objectives The fetal palate is not routinely imaged as part of the midtrimester fetal anomaly ultrasound, despite being associated with many syndromes. The “equal sign” depicts the lateral borders of the uvula on 2‐dimensional fetal ultrasound. We assessed the feasibility of adding the equal sign to the midtrimester fetal anomaly ultrasound.

Eosinophilic inflammation that begins in the juvenile stage causes hydronephrosis and urothelial cancer in mutant mice

Scientific Reports
Obstructive hydronephrosis is caused by various factors such as chronic inflammation and tumors. Eosinophils and chitinase-like proteins (CLPs) are involved in the pathogenesis of hydronephrosis in mice; however, the specific mechanisms remain unknown ...

Association Between Nephrolith Size and Location and Grade of Hydronephrosis

Life
This research investigated the unstudied impact, in 416 cases of stone-induced hydronephrosis detected radiographically in 369 patients, of stone size on the stone’s location in the urinary tract and on the hydronephrosis grade.

Rare Biallelic CTU2 Variants in an Individual With CAKUT: Clinical Characterization and Minigene Splicing Analysis

Molecular Genetics &Genomic Medicine, Volume 14, Issue 8, August 2026.
Exome sequencing in 200 CAKUT patients identified compound heterozygous rare CTU2 variants in one renal‐predominant case. Minigene splicing assays showed c.913C>T partially increased exon 9 skipping, supporting further case collection and kidney‐relevant studies to clarify the role of CTU2 in renal developmental phenotypes.

The Relationship of Pre- and Post-Operative Kidney Function and The Degree of Hydronephrosis Caused by Stones and Malignancy in Patients who Have Had A DJ Stent Installed

JBN (Jurnal Bedah Nasional)
Aim: This study aims to assess the relationships between ureum, creatinine, GFR and the degree of hydronephrosis, both before and after DJ stent installation.

Upper Urinary Tract Stone Disease: Practical Guidance for Early Assessment and Management

Trends in Urology &Men's Health, Volume 17, Issue 4, August 2026.
ABSTRACT Upper urinary tract stone disease is a common urological condition with high recurrence rates and a significant healthcare burden. Many patients initially present in community or primary care settings, where early assessment and triage influence patient safety, referral timing and subsequent urological management.

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

British Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...
