Purpose We evaluated the discordance between ureteroscopic biopsy and surgical
pathology findings for grading and staging upper tract urothelial carcinoma. We also sought …

Abstract Background and Purpose: Accurate assessment of upper-tract urothelial carcinoma
(UTUC) pathology may guide use of endoscopic vs extirpative therapy. We present a multi …

Introduction This study aimed to evaluate the concordance in tumor stage and grade
between ureteroscopic (URS) biopsy and radical nephroureterectomy (RNU) in patients with …

Five percent of urothelial carcinoma occurs in the upper urinary tract (UUT), a challenging
location to biopsy. We aim to evaluate concordance between biopsy, cytology, and resection …

Objective To assess the accuracy of ureteroscopic (URS) biopsies in predicting stage and
grade at final pathology in upper tract urothelial carcinoma (UTUC). Materials and methods …

Objective To report changes in grade and stage between initial diagnostic and repeat
biopsies or resection for urothelial carcinoma (UTUC) and investigate the consequences for …

OBJECTIVE: To determine the association between endoscopic biopsy grade and the final
pathologic characteristics at nephroureterectomy for upper tract urothelial carcinoma …

Context.—Ureteroscopic biopsy is the gold standard for the histopathologic diagnosis of
urothelial carcinoma of the upper urinary tract. Objective.—To assess the accuracy of …

Background With the development of kidney‐sparing surgery and neoadjuvant
chemotherapy, ureteroscopic biopsy (URSBx) has become important for the management of …

PURPOSE:: We assessed the diagnostic accuracy of a ureteroscopic multi-biopsy approach
to upper tract urothelial carcinoma compared with subsequently resected surgical …
