Intravesical explosion during transurethral electrosurgery.

Intravesical explosion is a very rare complication of transurethral resection of prostate and transurethral resection of bladder tumour operations. In vitro studies have shown that the gases produced during the procedure could result in a blast once they are mixed with air from the atmosphere. A 79-year-old male experienced an explosion in his bladder while undergoing a transurethral resection of bladder tumour.

Hypoxia-inducible factor 1 alpha expression correlates with angiogenesis and unfavorable prognosis in bladder cancer.

Introduction And Objectives: Hypoxia-inducible factor 1 alpha (HIF-1 alpha) is a critical regulatory protein of cellular response to hypoxia and is closely related to the triggering of the angiogenic process. We examined the relationship between hypoxia and angiogenesis, as well as their prognostic impact in patients with urothelial bladder cancer.

Methods: The immunohistochemical expression of HIF-1 alpha was evaluated in 93 formalin-fixed paraffin-embedded primary transitional cell carcinoma tissue samples.
