abstract: urinary bladder hemangiomas are very rare and accounting for 0.6% of all urinry bladder toumors. it is rare cause of hematuria. a 8-year old boy presented with painless gross hematuria for one week. he had past history of this problem 5 months ago. physical examination revealed no unusual findings. sonogeraphy and ct scan showed intraluminal bladder mass with exteravesical cyctic comp...

Human enhancer of filamentation 1 (HEF1) is a multidomain scaffolding protein that has been thought to play an important role in the tumor progression of various cancers. HEF1 expression has not previously been reported in urinary bladder carcinoma, and little is known about its prognostic significance. The aim of this study was to evaluate the expression patterns of HEF1 in urinary bladder car...

Botulinum toxin (BTX) belongs to a family of neurotoxins which strongly influence the function of autonomic neurons supplying the urinary bladder. Accordingly, BTX has been used as an effective drug in experimental therapies of a range of neurogenic bladder disorders. However, there is no detailed information dealing with the influence of BTX on the morphological and chemical properties of nerv...

BACKGROUND The frequency of over-expression of human epidermal growth factor receptor-2 (HER-2) in bladder cancer is one of the highest among all human malignancies. This over-expression is thought to play a role in aberrant proliferation of cancer cells. Studies on HER-2 expression in bladder carcinoma have shown heterogeneous results. PURPOSE The aim of the study was to evaluate the status ...

Small cell carcinoma of the urinary bladder is a rare and aggressive tumor resembling small cell carcinoma of the lung. Thyroid transcription factor 1 (TTF-1) expression is common in small cell carcinomas arising in the lung. However, studies of its expression in extrapulmonary small cell carcinomas have yielded varying results. Because information concerning the immunohistochemical profile of ...

Transitional cell carcinoma (TCC), a urinary bladder tumor with high mortality, is encountered commonly in dogs. Whereas overexpression of epidermal growth factor receptor (EGFR) is associated with development of human urinary bladder cancer, information on EGFR expression in canine TCC is lacking. In this study, EGFR protein and mRNA expression in canine normal bladder (n=5), polypoid cystitis...

Para (p)-phenylenediamine and its toxic metabolites induce excess reactive oxygen species formation that results in bladder voiding dysfunction. We determined the effects of synthetic Ni-containing superoxide dismutase mimics and the role of oxidative stress in p-phenylenediamine-induced urinary bladder dysfunction. P-phenylenediamine (60 μg/kg/day) was intraperitoneally administered for 4 week...

bladder calculi, a rare condition in the pediatric population, occur most commonly as a result of either migration from the kidney or urinary stasis in the bladder. we report the case of a 3-year-old boy with recurrent urinary tract infections (uti) secondary to bladder calculi formation on the sutures from a previous herniorrhaphy.a 3-year-old boy with previous history of herniorrhaphy present...

results during the period from jan 2000 to dec 2011, at our center, 19 children less than eighteen years of age underwent urinary diversion with yang-monti’s catheterizable stoma. the indications for urinary diversion was neuropathic bladder in eight, exstrophy bladder in seven , valve bladder syndrome in three and persistent urethral stricture in one. none of the children found cic difficult d...
