The histology and immunohistochemistry of free buccal mucosa and full-skin grafts after exposure to urine

1999

Objective To investigate the histological and immunohistochemical behaviour of free buccal mucosa and full-skin grafts after exposure to urine. Materials and methods A buccal mucosal graft and a full-skin graft were freely transferred into the bladder of 12 minipigs, after stripping the bladder mucosa. Endoscopic investigations were carried out 2 and 5 months after surgery, and the grafts examined after death at 7 months, both histologically and immunohistochemically. Results Shrinkage of the full-skin graft was apparent endoscopically in five cases. Of the nine full-skin grafts, four showed severe inflammatory reactions, two necrosis and two ulcerations. Conversely, the 10 buccal mucosal g…

The pathology of bladder cancer: An update on selected issues

2006

OBJECTIVE: To achieve a closer relationship between urologists and pathologists and to use a common language and identical objectives in the pathology of bladder cancer. METHODS AND RESULTS: Special emphasis was given to an analysis of the new World Health Organization (WHO) grading system, to the interpretation of the last Tumour-Nodes-Metastasis staging rules, and to identifying new markers of prognostic significance in clinical practice. A consensus was achieved on the main points. CONCLUSIONS: The 2004 WHO grading system must become acceptable to clinicians, perhaps by a minimal modification of the present terminology. Simple transurethral resection-biopsy should be expressed in terms o…
