Nerve growth factor (NGF) has been suggested to play a role in bladder pain by mediating inflammation (12) and functional changes in sensory and sympathetic neurons innervating the urinary bladder (5). Clinically, diseases such as interstitial cystitis/painful bladder syndrome (IC/PBS) have been associated with elevated urinary levels of NGF (10) and the urothelium of individuals with IC/PBS pr...

background : e-cadherin is a trans-membrane glycoprotein that plays a critical role in many aspects of cell adhesion as well as establishment and maintenance of epithelial cell polarity. loss of the adhesive function of e-cadherin seems to promote invasive and metastatic properties of neoplastic cells.   objectives: the present study is a retrospective study aiming to evaluate the loss of e-cad...

Overactive bladder (OAB) is a syndrome involving urinary urgency with accompanying increased daytime urinary frequency and nocturia, with or without urgency urinary incontinence, in the absence of an urinary tract infection or other obvious pathology. The detailed OAB pathophysiology remains unclear. There is evidence that OAB pathogenesis also includes abnormal bladder paracrine activity, asso...

The current management of diseases of urinary bladder requiring resection is by augmentation cystoplasty or transplantation of ureters. Transplantation of ureters is associated with morbidity and mortality. Ideal management will be by regenerating urinary bladder in vivo. Neo-regeneration of tissues and organs like abdominal wall, aponeurosis etc., has been attempted and patented. After neo-reg...

Non-traumatic rupture of the urinary bladder is termed “spontaneous rupture of the urinary bladder”. Although this disorder is relatively rare, when the bladder ruptures into the abdominal cavity, urine leaking into the abdominal cavity leads to the development of urinary peritonitis. We encountered seven patients with spontaneous rupture of the urinary bladder at our institution between 1987 a...

Metastases of melanoma to the urinary bladder are infrequent. Even rarer are metastases to the urinary bladder from uveal melanoma, with only 3 cases published in the literature so far. Herein we present a case of a 77-year-old male patient who presented with metastatic melanoma to the urinary bladder. The patient's history included the diagnoses of uveal melanoma treated with radiation 25 year...

Since the sodium salt of ascorbic acid (AA) promoted two-stage urinary bladder carcinogenesis in rats, whereas AA itself did not, the roles of the urinary sodium ion concentration and pH on urinary bladder carcinogenesis were investigated. Male F344 rats were given 0.05% N-butyl-N-(4-hydroxybutyl)nitrosamine in their drinking water for 4 weeks and then treated with basal diet containing 5% AA p...

Bladder leiomyomas are benign mesenchymal neoplasms and very rare urinary tumors that represent\0.5 % of all bladder tumors, with only 250 cases reported worldwide till date [1]. The incidence of bladder leiomyoma is 3 times higher in women than in men. Typically, it occurs in the fourth and fifth decades of life. We present here a case of leiomyoma of urinary bladder in middle-aged woman with ...

Primary urinary bladder adenosquamous carcinoma is extremely rare and only a few cases have been reported in English literatures. Its biological behavior remains unclear. Here we reported a 60-year-old male patient with lower limb deep venous thromboses associated with primary urinary bladder adenosquamous carcinoma. A color ultrasonography showed right stock total venous thrombosis and right g...

The aim of the present study is to verify the functional and anatomical neural pathways which innervate the urinary bladder in the central nervous system of the rat. To identify the functional neural pathway, the urinary bladder was stimulated by infusing formalin for 2 h. Then, brain and spinal cord were dissected out and immunohistochemistry was done by using anti-c-fos antibody. Many c-fos i...
