Robot-assisted excision of partially obstructing ureteral fibroepithelial polyp in a child: A case report and review of the literature

Journal of Pediatric Surgery Case Reports, 2022
Background: Fibroepithelial polyps are benign tumors located in the upper ureter and ureteropelvic junction. Given their location in rare cases they can cause hydronephrosis.

Single‐Cell Dissection of the Biological Function and Molecular Features Underlying the Micropeptide LSMEM1 in Kidney

Advanced Science, EarlyView.
LSMEM1, an evolutionarily conserved micropeptide with extreme hydrophobicity (aliphatic index═113) and dynamic amphiphilicity (GRAVY═0.017), features a strong α‐helical transmembrane anchor (residues 64‐86). Single‐cell analysis reveals its critical role in renal lipid homeostasis.

Scintigraphy and Doppler ultrasonography for the evaluation of obstructive urinary calculi [PDF]

, 2001
Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans for assessment of renal function.

NLRP3 Deficiency Attenuates Renal Fibrosis and Ameliorates Mitochondrial Dysfunction in a Mouse Unilateral Ureteral Obstruction Model of Chronic Kidney Disease

Mediators of Inflammation, 2017
Background and Aims. The nucleotide-binding domain and leucine-rich repeat containing PYD-3 (NLRP3) inflammasome has been implicated in the pathogenesis of chronic kidney disease (CKD); however, its exact role in glomerular injury and tubulointerstitial ...

Mapping the Tissue‐of‐Origins of Mesenchymal Stromal Cells in Injury Repair

Advanced Science, EarlyView.
This study maps mesenchymal stromal cells (MSCs) across multiple tissues, revealing that bone marrow–derived MSCs mobilize monocytes via CCL2 to promote systemic inflammation but do not migrate to distant organs to form fibrotic or tumor stroma. Instead, local MSCs dominate tissue remodeling, suggesting a “two‐hit” model linking systemic inflammation ...

Use of percutaneous nephrostomy and ureteral stenting in management of ureteral obstruction.

World Journal of Nephrology, 2016
The management options for ureteral obstruction are diverse, including retrograde ureteral stent insertion or antegrade nephrostomy placement, with or without eventual antegrade stent insertion.

Under‐Urine‐Adhered Supramolecular Hydrogel with Linearly Sustained Quercetin Release Facilitates Hemorrhagic Cystitis Healing via Inflammation Regulation

Advanced Science, EarlyView.
A supramolecular gelatin‐based hydrogel adhesive was engineered for hemorrhagic cystitis management. It provides robust wet‐tissue adhesion, rapid hemostasis, sustained quercetin release, effectively restoring the bladder barrier via anti‐inflammatory and antioxidant actions.
