Ureteroscopic removal of mildly migrated stents using local anesthesia only.

Purpose: In the outpatient office setting we evaluated the feasibility and efficacy of ureteroscopic removal of upward migrated ureteral stents using local or no anesthesia.

Materials And Methods: Prospectively 37 patients with mild upward stent migration underwent ureteroscopic stent removal under local or no anesthesia. Stent migration was always below the pelvic brim.

Associations between coronary heart disease, obesity and histological prostate cancer.

Objective: The present study investigates the possible associations between coronary heart disease and histological prostate carcinoma in autopsy material.

Material And Method: The material of our study, were 116 men between 55 years and 98 years of age, who died in the period of August 2002-January 2005. The initial segment of the aorta and the prostate glands of all cadavers were removed while the initial 30 mm of the left and right coronary arteries and the peripheral zone of the prostate gland underwent pathologic examination.

Association between testicular microlithiasis, testicular cancer, cryptorchidism and history of ascending testis.

Objective: To prospectively determine the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer and other conditions such as cryptorchidism or history of ascending testis.

Materials And Methods: 391 men who were referred to our institutions between July 2002 and May 2005 for any type of symptoms from the testicles, underwent physical and scrotal ultrasound examination. The presence of testicular microlithiasis, the number of lesions and the involvement of both testicles in relation to the symptoms as well as the coexistence of other lesions were studied.

Associations among benign prostate hypertrophy, atypical adenomatous hyperplasia and latent carcinoma of the prostate.

Aim: To investigate the frequency of atypical adenomatous hyperplasia (AAH) and its associations with benign prostate hypertrophy (BPH) and latent histological carcinoma of the prostate (LPC) in autopsy material.

Methods: Two hundred and twelve prostate specimens obtained from autopsy material were subjected to whole mount analysis in an attempt to investigate the associations among BPH, AAH and LPC.

Results: Most histological carcinomas and AAH lesions were found in enlarged prostates with intense hypertrophy.

Hypoxia-inducible factor 1 alpha expression correlates with angiogenesis and unfavorable prognosis in bladder cancer.

Introduction And Objectives: Hypoxia-inducible factor 1 alpha (HIF-1 alpha) is a critical regulatory protein of cellular response to hypoxia and is closely related to the triggering of the angiogenic process. We examined the relationship between hypoxia and angiogenesis, as well as their prognostic impact in patients with urothelial bladder cancer.

Methods: The immunohistochemical expression of HIF-1 alpha was evaluated in 93 formalin-fixed paraffin-embedded primary transitional cell carcinoma tissue samples.

Multifocality of renal cell tumors is a factor to consider before performing a partial nephrectomy.

Background: We conducted a retrospective analysis of radical nephrectomies performed in our clinic in order to evaluate the incidence of multifocality in relation to the stage, grade, size and histological type.

Materials And Methods: Preoperative imaging studies and the final pathological results of surgical specimens were reviewed. Separate primary tumors at a distance of more than one cm from the primary tumor were counted.
