A Case of Urachal Malacoplakia that Seems Like Urachal Cancer.

Background: Urachal masses observed in adults should be considered malignant unless they are confuted. It is very difficult to differentiate between malignant or benign lesions, including especially calcified foci and solid areas.

Case Report: Our case was a 63-year-old male patient who was diagnosed as Behçet's Disease 26 years ago.

Value of dynamic contrast-enhanced MRI and correlation with tumor angiogenesis in bladder cancer.

Objective: The aim of this study was to investigate dynamic contrast-enhanced MRI (DCE-MRI) for the noninvasive measurement of bladder cancer angiogenesis by correlation with microvessel density, histologic grade, and tumor staging, and to predict the outcome of local recurrence.

Materials And Methods: Twenty-four patients with bladder cancer were examined using DCE-MRI. Hemodynamic parameters obtained by DCE-MRI included peak time enhancement in the first minute (E(max/1)) after contrast administration, second minute (E(max/2)), third minute (E(max/3)), fourth minute (E(max/4)), and fifth minute (E(max/5)), and the steepest slope.

Pre-treatment hemoglobin levels are important for bladder carcinoma patients with extravesical extension undergoing definitive radiotherapy.

Purpose: To evaluate prognostic factors affecting local control (LC), distant metastases-free survival (DMFS) and overall survival (OS) in bladder carcinoma patients undergoing extravesical extension.

Patients And Methods: We retrospectively reviewed the charts of 61 consecutive patients with T3 or T4 bladder carcinoma, treated with definitive radiotherapy from 1999 through 2007.

Results: Median age was 69 years and follow-up was 29 months.

Influence of N-acetylcysteine on renal toxicity of cadmium in rats.

The aim of this study was to investigate the ability of N-acetylcysteine (NAC) to prevent cadmium (Cd)-induced renal damage and whether NAC would reverse cadmium damage to the kidney. Fifty adult male rats were divided into five experimental groups: group 1 received tap water for 3 months and 7 days, group 2 received cadmium chloride (CdCl(2)) for 3 months, group 3 (NAC cotreatment group) received CdCl(2) and 0.5% NAC in tap water for 3 months, group 4 received CdCl(2) in tap water for 3 months and 3 months later received only tap water for 7 days, and group 5 (NAC posttreatment group) received CdCl(2) in tap water for 3 months and 3 months later received 2% NAC in tap water for 7 days.

Case report: subcutaneous metastasis from small cell carcinoma of the prostate.

Pure primary small cell carcinoma of the prostate (SCCP) is an extremely rare entity. Natural history of this tumor is similar to that of the bronchogenic small cell carcinoma. Several theories of histogenesis have been proposed.

Serum, urinary and stone zinc, iron, magnesium and copper levels in idiopathic calcium oxalate stone patients.

Many theories have been put forward to explain the mechanism of stone formation and growth. The aim of this study was to investigate the urinary, serum and stone levels of zinc, iron, magnesium, and copper in patients with calcium oxalate stones and to investigate urinary and serum element levels in healthy controls and to find a possible connection between the elements and calcium oxalate stone formation. A total of 104 patients with calcium oxalate stones ranging in age from 3 to 79 years (mean 44.

Renal angiomyolipoma with malignant transformation, simultaneous occurrence with malignity and other complex clinical situations.

Renal angiomyolipoma is a benign kidney tumor, which is characterized by the presence of mature or immature fat tissue, thick-walled blood vessels, and smooth muscles. However, there is a rare possibility of transformation to a malignancy. This transformation could be toward sarcoma.

Giant unilateral abdominoscrotal hydrocele in an adult: case report.

Abdominoscrotal hydrocele (ASH) is an apparently highly uncommon clinical entity especially in childhood. While hydrocele is among the commonest inguinal anomaly in adult, its extreme form ASH is infrequently reported form. ASH consists of two large sacs, both abdominal and scrotal, connecting with the inguinal canal.

Giant prostatic urethral calculus associated with urethrocutaneous fistula.

Urethral stones in men are rare clinical entity and most of them migrate from the urinary bladder. Urethral stones are rarely formed primarily in the urethra and are usually associated with urethral strictures or diverticula. We report a 41-year-old man with giant prostatic urethral stone (5.

Chondrosarcoma of the pubis imitating bladder tumor radiologically: a case report.

Chondrosarcoma is a rare tumor that more frequently involves the pelvic bones, the femur, and the humerus. The rareness of the tumor makes the diagnosis difficult. Malignant cartilage tumors typically have an unstable radiographic appearance.

The use of human dura mater as an interposition graft in the treatment of vesicovaginal fistula.

Purpose: In this prospective study we aimed to describe our new technique; dehydrated human dura mater as an interposition graft in patients undergoing benign vesicovaginal fistula repair (VVF).

Patients And Methods: Eleven patients with benign VVFs aged 38-73 years were operated with dura mater interposition technique at our institution between July 1996 and February 2002. In all patients fistula were secondary to abdominal hysterectomies with benign diseases and two had undergone previous transvaginal surgery.

Multiple primary malignant neoplasms in urologic patients.

Methods: Second primary cancers constitute approximately 9-10% of malignancies diagnosed in the United States. We aimed to show the risk and incidance of second primary tumor occuring associated to urologic tumors and show the distrubution of tumors in Tracia region. We retrospectively examined the patients' files with the diagnosis of malignant disease between the years 1985-2000.

A life-threatening infection: Fournier's gangrene.

Fournier's gangrene is a life-threatening disorder in which infection of the perineum and scrotum spreads along fascial planes, causing soft tissue necrosis. If urgent surgery is delayed, the disease will soon result in septic shock, multiorgan failure, and death. In this study, we present 21 patients with Fournier's gangrene who were treated in period between 1994 and 2001.
