Cases Of High-grade Urothelial Carcinoma Research Articles

Transitional Cell Carcinoma Due to Chronic UroLume Stent Irritation

UroLume stents have been used for >15 years to improve the voiding dynamics in patients with benign prostatic hyperplasia and urethral stricture disease. Common complications include stent migration, stricture within the stent, and urothelial hyperplasia, any of which could require stent removal, which itself carries morbidity. We report a case of high-grade urothelial carcinoma associated with chronic UroLume application.

High‐grade urothelial carcinoma: Comparison of SurePath liquid‐based processing with cytospin processing

There is limited literature available comparing SurePath (SP) with conventional cytospins (CS) for urine cytology specimens, especially urothelial carcinoma. In this study, urinary tract cytology cases of high-grade urothelial carcinoma were assessed on SP and CS slides. Also, the morphologic differences of high-grade urothelial carcinoma between SP and CS were evaluated on a total of 35 cases of high-grade urothelial carcinoma. SP showed that the tumor cells tend to present as three-dimensional groups and have a smaller cell size than CS. In terms of nuclear features, SP and CS were found to be comparable in morphologic assessment of the tumor cells, with CS providing a slightly better visualization.
