Abstract Gangrenous cystitis is a pathology that rarely encountered in current urological practice. It due to necrosis of the bladder wall, which may be superficial or involve entire wall. Its exact pathogenesis unknown, but several factors make its diagnosis based on cystoscopy imaging. surgical treatment depends operative finding. In this report, authors report case gangrenous 73-year-old pat...

The epigenetic alteration of aberrant hypermethylation in the promoter CpG island of a gene is associated with repression of transcription. In neoplastic cells, aberrant hypermethylation is well described as a mechanism of allele inactivation of particular genes with a tumor suppressor function. To investigate the role of aberrant hypermethylation in the biology and progression of urothelial ca...

background: radiotherapy treatment planning requires different dosimetric quantities as input in order to calculate a desired dose distribution. this study has been focused to evaluate the depth dose characteristics of superficial x-rays being used for radiotherapy treatment. materials and methods: computerized 3-d water phantom of multi-data system was used. the measurements were made through ...

BACKGROUND Tumor recurrence following radical cystectomy for a low-grade superficial transitional cell carcinoma (TCC) is exceedingly uncommon and has not been reported previously. CASE PRESENTATION We describe a case of a young male presenting with anorexia, weight loss and a large, painful locally destructive pelvic recurrence, ten years after radical cystoprostatectomy. The pathology was c...

In a retrospective study of 185 patients with transitional cell carcinoma of the renal pelvis and ureter, of whom 127 were treated by total nephroureterectomy and 58 by conservative resection, the survival of those with superficial well differentiated tumours was greater than 90% in each group. When urothelium was left behind after conservative resection, there was a 22% rate of recurrence on t...

OBJECTIVES On behalf of the European Association of Urology (EAU) guidelines for diagnosis, therapy and follow-up of bladder cancer patients were established. Criteria for recommendations were evidence based, and included aspects of cost-effectiveness and clinical feasibility. METHOD A systematic literature research using Medline Services was conducted. References were weighted by a panel of ...

AIMS To establish whether there is a difference in recovery of salivary function with bilateral superficial lobe parotid-sparing intensity-modulated radiotherapy (BSLPS-IMRT) versus contralateral parotid-sparing IMRT (CLPS-IMRT) in patients with locally advanced head and neck squamous cell cancers. MATERIALS AND METHODS A dosimetric analysis was carried out on data from two studies in which p...

Objective: To describe our experience in managing two cases of primary malignant parotid lymphoma. Methods: Design: Case Report Setting: Tertiary University Referral Center Patients: Two Results: Both patients underwent superficial parotidectomy. Despite recurrence in one, the disease was controlled with conservative management. However, the disease was more aggressive in the other, requiring a...

A 66-year-old woman was operated on in 1988 for an endometrial adenocarcinoma, after which she received adjuvant radiotherapy. The patient presented with 6month, progressive iron-deficiency anemia. A complete endoscopic study (esophago-gastrosco-duodenoscopy and ileocolonoscopy) was performed; mucosal edema with superficial whitish spots in the terminal ileum (fig. 1A) was observed. Nonspecific...

There are three historically recognized methods of intra-arterial infusion for oral cancer: Conventional intra-arterial infusion via the superficial temporal artery: Superselective intra-arterial infusion via the femoral artery (Seldinger method), New superselective intra-arterial infusion via the superficial temporal artery. Here we report a recent instance of daily concurrent chemoradiotherap...
