Morphologic characteristics of the urothelial bladder tumors

Structure of the initial lymphatics of the human urinary bladder with invasive urothelial tumors.

The ability of urothelial tumors of the urinary bladder to metastasize via the lymphatic circulation and the extent of metastatic involvement of regional lymph nodes is an important parameter in the staging and prognosis of these neoplasms. Accordingly, we examined the site and morphology of initial lymphatic vessels in the mucosa of the human urinary bladder in patients with invasive transitio...

Morphologic Characteristics of the Vallis

Introduction: The Vallis Schröteri exists on the Aristarchus Plateau (305-313 °E, 22-30 °N) which is a topographic high surrounded by basaltic maria. The rille appears a singular sinuous rille as meandering primary rille including a more meandering inner rille. Typical sinuous rilles are 20 to 40 km in length and less than 1 km in width [1], however, the primary rille of Vallis Schröteri has be...

Bladder: Urothelial carcinomas

Production of urothelial tumors in the heterotopic bladder of rat by benzidine derivatives.

Male Fischer rats which had been implanted with a heterotopic bladder were randomly divided into five groups and their heterotopic bladders were instilled once a week for 20 weeks with 0.5 ml phosphate-buffered saline:dimethyl sulfoxide solution (4:1) or this solution containing 1 mumol benzidine (BZ), N'-hydroxy-N-acetylbenzidine, the N'-glucuronide of N'-hydroxy-N-acetylbenzidine, or the N-gl...

The Changing Face of Urothelial Bladder Cancer

Survival for patients undergoing radical cystectomy for urothelial bladder cancer has remained relatively unchanged throughout the past three decades [1]. This is despite improvements in surgical technique, supportive care during surgery, administration of systemic therapy, and lastly, despite evidence of an associated survival benefit, neoadjuvant chemotherapy [2]. While the reason for this la...
