Local excision of urothelial cancer of the upper urinary tract.

1986

Abstract In 9 of 93 patients (9.7%) with urothelial cancer of the upper tract (7 renal pelvis tumors, 3 ureteral tumors), conservative surgery was employed using a free peritoneal autotransplant for replacement of the renal pelvis in 5 kidneys. Absolute indications for conservative surgery were solitary kidneys/nonfunctioning contralateral kidneys in 4 patients and bilateral tumors in 1 patient. Local recurrences developed 1-3 years after operation in 4 of 6 kidneys (3 patients), 3 of which had grade-2 and grade-3 primary lesions. All patients were treated successfully by repeated local excision. In the presence of a normal contralateral kidney, local tumor excision was done electively in 4…

Segmental Ureterectomy Versus Radical Nephroureterectomy in Older Patients Treated for Upper Tract Urothelial Carcinoma

2022

Introduction: The world population is ageing and surgical procedures for older patients are associated with higher perioperative morbidity and mortality rates than in younger patients. Segmental ureterectomy (SU) has been proposed as an alternative to radical nephroureterectomy (RNU) for selected upper tract urothelial carcinomas (UTUC), to reduce post-operative morbidity, and preserve renal function. The aim of this study was to compare RNU and SU in terms of post-operative complications, functional outcomes, and overall survival (OS) in older patients treated for UTUC. Materials and methods: Data of patients aged 75 years or older and treated for UTUC were included. The primary outcome wa…

Segmental resection of distal ureter with termino-terminal ureteric anastomosis vs bladder cuff removal and ureteric re-implantation for upper tract …

2019

OBJECTIVES: To compare overall (OS), cancer-specific (CSS), recurrence free survival (RFS) and post-operative renal function among patients affected by upper tract urothelial carcinoma (UTUC) of the distal (lower lumbar and pelvic) ureter, electively treated with segmental resection and termino-terminal anastomosis (TT) vs bladder cuff removal and ureteral re-implantation (RR). PATIENTS AND METHODS: A multicentre retrospective study, including 84 patients diagnosed with UTUC of the distal ureter and treated with TT or RR, is presented. The primary endpoint was to compare TT and RR in terms of OS, CSS and RFS. As a secondary outcome we compared the post-operative creatinine values as an inde…

Elective segmental ureterectomy for transitional cell carcinoma of the ureter: Long-term follow-up in a series of 73 patients

2012

What's known on the subject? and What does the study add? Upper Urinary Tract (UUT) Transitional Cell Carcinoma (TCC) is an uncommon disease and represents approximately 5% of all urothelial carcinomas. We report our series on 73 patients treated with Kidney Sparing Surgery for UUT TCC. Good results have been achieved in terms of oncological outcome comparing this conservative approach to the radical nephrourectomy. OBJECTIVES: • To report the long-term oncological outcome in patients with transitional cell carcinoma of the ureter electively treated with kidney-sparing surgery. • To compare our data with the few series reported in the literature. PATIENTS AND METHODS: • We considered 73 pat…

Effect on postoperative survival of the status of distal ureteral margin: The necessity to achieve negative margins at the time of radical cystectomy.

2015

Background: Despite several studies, the adequate management of positive distal ureter margins at the time of radical cystectomy (RC) remains controversial. Particularly, it is not clear whether the achievement of negative distal ureter margins at the intraoperative frozen sections (IFS) affects postoperative cancer-specific mortality (CSM). Methods: In all, 1,447 consecutive patients treated with RC at a single center between January 1987 and August 2014 were considered. Multivariable (MVA) logistic regression analyses were used to determine predictors of positive IFS. MVA Cox regression analyses were used to test the effect on CSM of intraoperative conversion to negative margins. Results:…

Handling and pathology reporting of specimens with carcinoma of the urinary bladder, ureter, and renal pelvis.

2003

Abstract Objective: Pathologists play a pivotal role in the diagnosis and in the report of the pathological features related to prognosis. Methods: To meet these endpoints, the following issues must be accomplished: adequate information about the patient history, proper handling of the specimens, identification of the reliable histopathological techniques necessary to reach the more detailed diagnostic information and evaluate the prognostic variables, and a standardized pathological report. Results: Recent efforts to standardize the histopathological evaluation have generated significant confusion among the urological and pathological communities as well. No consensus has been achieved abo…
