[Preliminary study on the expression of Toll-like receptors 7 and 8 in bladder urothelial tumors].

The aim of the study was to demonstrate the expression of Toll-like receptor (TLR)-8 and to confirm the expression of TLR-7 on bladder transitional cell carcinomas (TCCs) analyzing the changes in expression between low-grade (LG) and high-grade (HG) and between non-muscle invasive (NMIBC) and muscle-invasive (MIBC) bladder cancers. In our study, 25 patients who underwent transurethral resection (TURB) for bladder TCC have been selected. Thirteen of those had an LG form,while the other cases were classified as HG; the lesions were NMIBC in 18 patients and MIBC in the others seven.

A case of gross haematuria due to an ureteric-iliac artery fistula.

A case of gross haematuria due to an ureteric-iliac artery fistula We report a case of a 75-year-old man presented with gross haematuria and left hydronephrosis due to an ureteric iliac- artery fistula . Medical history included a previous positioning of aorto-bisiliac graft and an iliac artery stent placed to exclude an hypogastric aneurysm. A retrograde pyelography revealed a compression of the middle ureter and an extravasation of contrast at that level, for this reason a double J stent was inserted.

[Current role of prostatic transrectal ultrasound in the diagnosis of CaP].

Introduction: Cancer of the prostate (PCa) is now recognized as one of the most important medical problems facing the male population. In Europe, PCa is the most common solid neoplasm, with an incidence rate of 214 cases per 1000 men, outnumbering lung and colorectal cancer (1). According to the EAU guidelines, the main diagnostic tools to obtain evidence of PCa include DRE, serum concentration of PSA and transrectal ultrasonography (TRUS).

Acute scrotum secondary to filarial infection: a case report.

A 23-year-old man immigrated from Sri Lanka came to our observation for an acute painful volume increase of the right scrotum without fever. Clinical examination suggested a diagnosis of testis torsion. An exploratory surgical procedure was performed.

Correlation between induction of DNA fragmentation in urinary bladder cells from rats and humans and tissue-specific carcinogenic activity.

Seven chemicals, six of which are known to induce epithelial neoplasms of the urinary bladder in rats, were assayed for their ability to induce DNA damage in primary cultures of rat and human cells from urinary bladder mucosa, and in urinary bladder, liver and kidney of intact rats. Significant dose-dependent increases of DNA fragmentation, as measured by the Comet assay, were obtained in cells from both rats and humans with the following concentrations of five test compounds: 2-naphthylamine and N-nitrosodi-n-butylamine 0.5 and 1 mM, phenacetin 2 and 4 mM, cyclophosphamide from 2 to 8 mM, and o-toluidine 16 and 32 mM.

Observational multicentric trial performed with doxazosin: evaluation of sexual effects on patients with diagnosed benign prostatic hyperplasia.

Introduction: The aim of our study is to verify the effects of doxazosin on sexual function in patients with benign prostatic hyperplasia (BPH).

Materials And Methods: We enrolled 102 patients with BPH, selected by nine Italian Urology Departments. Patients were evaluated with the International Prostatic Symptom Score (I-PSS) and divided into two groups: those with intact sexual activity and those with erectile dysfunction.

Femoral nerve palsy caused by a self-retaining polyretractor during major pelvic surgery.

Postoperative femoral neuropathy is not a well-recognized complication in urology. We report 2 cases of femoral nerve palsy due to compression ascribed to the use of the self-retaining retractor. In the first case, the left femoral nerve was injured, and in the second case nerve injury was bilateral and synchronous.
