Fibromyxoid Nephrogenic Adenoma Mimicking Renal Cell Carcinoma: A Diagnostic Pitfall in Fine‐Needle Aspiration Cytology

Diagnostic Cytopathology, Volume 54, Issue 10, Page E236-E239, October 2026.
ABSTRACT Nephrogenic adenoma (NA) is a benign lesion of the genitourinary tract that may mimic malignancy both clinically and histologically. The fibromyxoid variant (FMNA), characterized by spindled cells in myxoid stroma, presents additional diagnostic challenges due to its rarity and overlapping features with renal cell carcinoma (RCC).

A Novel Technique for the Distal Ureter and Bladder Cuff During Nephroureterectomy: Thulium Laser Resection

Trends in Urology &Men's Health, Volume 17, Issue 5, October 2026.
ABSTRACT The aim of this study was to evaluate the safety and feasibility of a novel technique involving the use of the two‐micron thulium fibre laser (Tm‐laser) to perform bladder cuff excision (BCE) during radical nephroureterectomy (RNU). We conducted a retrospective review of all patients undergoing RNU with BCE for upper tract urothelial carcinoma
