OBJECTIVES: Transitional cell carcinoma in situ (CIS) of the upper urinary tract is a
relatively rare disease, and treatment guidelines remain to be defined. In this study, we …

Purpose In patients with urothelial carcinoma CIS (carcinoma in situ) generally has a poor
prognosis. However, to our knowledge the outcomes of pure/primary CIS and the behavior …

Purpose: We analyze the evolution of superficial transitional cell carcinoma in the intramural
distal ureter treated with transurethral resection. Materials and Methods: A total of 19 …

OBJECTIVES: To evaluate the effect of a history of bladder carcinoma in situ (CIS) on
relapse and survival after surgical management of metachronous upper tract urothelial …

Objectives To evaluate the pathologic findings and outcomes after distal ureterectomy for a
retained ureteral segment following incomplete nephroureterectomy for urothelial carcinoma …

Purpose Carcinoma in situ of the urinary tract is a high grade form of nonmuscle invasive
urothelial cancer. Our understanding of this entity in the upper tract is poor, and case …

Purpose: We compared the oncologic outcomes of radical nephroureterectomy, distal
ureterectomy and endoscopic surgery for elective treatment of clinically organ confined …

Objectives To characterize the site and clinical implications of intravesical recurrence after
radical nephroureterectomy for upper urinary tract urothelial carcinoma. Methods Patients …

Objective: Conservative treatment (CT) with flexible ureteroscopy and laser ablation is an
alternative to radical nephroureterectomy (RNU) for the treatment of the upper urinary tract …

PURPOSE: The clinical impact of ureteral carcinoma in situ identified at the time of radical
cystectomy for bladder cancer has been poorly studied. We discuss our experience with this …
