Introduction: Our aim in this study was to investigate the prevalence and correlation with coronary artery calcium scores (CACS) and erectile dysfunction (ED) among hemodialysis patients.

Patients And Methods: Thirty-five male patients with chronic renal failure were selected to participate in this study. All patients underwent examinations for CACS using 16-channel multidetector computed tomography.

Introduction: In this study, the effect of age on the prognosis of testicular germ cell tumors in patients over 40 was investigated.

Materials And Methods: Ninety-three patients with testicular germ cell tumor who were 40 years old and over were identified in our germ cell tumor database. Patients were grouped according to their age with those between 40 and 44, 45 and 49 and 50 and over constituting groups I, II and III, respectively.

Purpose: The relative risk of germ cell testicular tumor is significantly higher in patients with a testicular tumor history. We reviewed histological and clinical features in 30 patients with bilateral tumors treated at 2 academic centers in Turkey.

Materials And Methods: Of 987 patients with testicular germ cell tumors 30 (3.

Our aim was to investigate the semen variables and hormone profiles among transplant patients who received kidneys during adolescence. Seven postpubertal transplant patients who underwent successful renal transplantation during adolescence (13-19 years; 3 were preemptive) were enrolled in our clinical follow-up. Serum levels of prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone were checked together with the semen analysis.

Objectives: To investigate the presence of urinary cytokines, after bacillus Calmette-Guérin (BCG) therapy, in order to provide further insight into the mechanisms of action of intravesical BCG therapy.

Method: Urine levels of interleukin-2 (IL-2), interleukin-2 receptor (IL-2R), and tumor necrosis factor alpha (TNF alpha) levels were determined in 34 patients with superficial bladder tumors after a six-week course of intravesical BCG therapy. The urine samples were obtained at the fifth hour following the sixth course of therapy and the determinations were made by using an (enzyme-linked immunosorbent assay (ELISA)) technique.

We examined the nature of contralateral damage following unilateral orchitis to see if an immunologically mediated mechanism was present. Experimentally induced orchitis in 18 white New Zealand rabbits were examined and compared to 20 in the control groups. Serum antisperm antibody presence and bilateral testicular biopsies (Johansen biopsy score, mean seminiferous tubule diameter) were examined and pregnancy rates were noted.

Serum ferritin levels in 32 patients with renal cell carcinoma were evaluated preoperatively and postoperatively. Serum ferritin concentration was significantly higher in renal cell carcinoma patients compared to controls (259.10 versus 61.

An immunohistochemical staining method was used to study transferrin receptors (TFR) in bladder tissue from 10 patients with benign conditions and 33 with bladder cancer. All patients with bladder cancer were followed up by cystoscopy at intervals of 3 months (mean follow-up period 11 months). The relationship between TFR activity and recurrence rates was investigated.

Forty-nine patients with ureteral colic were included in this prospective double-blind study investigating the analgesic efficacy and side effects of a prostaglandin synthetase inhibitor Diclofenac sodium (Voltaren) versus a spasmolytic drug Tropenzilium bromide (Palerol). The analgesic efficacy and side effects of the calcium antagonist Nifedipine (Nidilat) applied sublingually in ureteral colic were also investigated. It was concluded that diclofenac sodium was more efficient for relieving pain due to acute ureteral obstruction and had fewer side effects than spasmolytic drugs.

During an 18-year period, 17 patients with renal pelvic and 8 with ureteral carcinoma were seen in our clinic. The lesion was transitional cell carcinoma in 23 patients, and epidermoid and anaplastic carcinoma, respectively, in 2 others. Because of frequent tumour recurrence in the lower tract, we recommend total nephroureterectomy including a cuff of the bladder as the treatment of choice for renal pelvic neoplasms.

Thirty-four patients with TO carcinoma of the prostate were reviewed in an attempt to correlate their clinical progress with the histopathological features of the tumour at presentation. Two different grading systems were used. It was found that no matter which system was used, the poorer the histopathological grade the poorer the prognosis.

The effect of Ergobromocriptine treatment on serum testosterone and prolactin levels in 15 patients with prostatic carcinoma and 15 patients with benign prostatic hyperplasia was examined. The prolactin levels which were elevated in patients with prostatic carcinoma showed a significant decrease after suppression with Ergobromocriptine. The selective effect of Ergobromocriptine on prolactin levels of patients with prostatic carcinoma may control the progression of the disease.
