Main Pathological Changes of Benign Ureteral Strictures.

ABSTRACT:

Objective

To identify the pathological classification of benign ureteral strictures according to the histological features and explore the relationship between various pathological types and inflammatory cells, fibroblasts, and collagen.

Patients and methods

Thirty one specimens from patients diagnosed with ureteral strictures between 2013 and 2021 were included and classified according to the histopathological characteristics. The number of fibroblasts and inflammatory cells was counted, and the proportion of type I and type III collagen in ureteral stricture tissues was detected by picrosirius red staining.

Results

We identified three types of benign ureteral strictures in 31 specimens: inflammatory cell infiltration (n = 10, 32%), fibroplasia (n = 14,
