Introduction The correlation between erectile dysfunction (ED) and coronary artery disease has been emphasized and ED has been recognized as a potential independent risk factor and/or predictor of coronary artery disease (CAD). We evaluated the association between the number of occluded coronary arteries in myocardial infarction (MI) patients with the severity of ED, and investigated the influence of related risk factors in our study group. Materials and Methods 183 male patients who underwent coronary angiography because of acute MI from November 2009 to May 2011 were included. Following the stabilization of patients after the treatment, each patient was evaluated for erectile functionality. Risk factors such as age, diabetes, smoking, waist circumference, hypertension, and hematologic parameters were recorded. Results Among 183 patients with a mean age of 55.2 years who underwent coronary angiography due to acute MI, 100 (54.64%) had ED, while the ED rate was 45.36% (44/97) in cases of single-vessel disease, 64.5% (31/48) in cases of two-vessel disease, and 65.7% (25/38) in cases of three-vessel disease. The mean IIEF score was 24.2 ± 4.3, 20.4 ± 4.9 and 20.5 ± 4.2 for single or two or three-vessel disease, respectively. The presence of hypertension aggravated ED only in patients with three-vessel disease and increased total and LDL cholesterol levels in patients with single-vessel or two-vessel disease were accompanied by significantly decreasing IIEF scores. Conclusion The severity of ED correlated with the number of occluded vessels documented by coronary angiography, in male patients with acute myocardial infarction. In addition, the presence of hypertension had a significant influence over erectile function only in patients with three-vessel occlusion.

PURPOSE: To evaluate hyoscine N-butyl bromide (HBB) and three different alpha-1 blockers in the treatment of distal ureteral stones. MATERIALS AND METHODS: A total of 140 patients with stones located in the distal tract of the ureter with stone diameters of 5 to 10mm were enrolled in the present study and were randomized into 4 equal groups. Group 1 received HBB, Group 2 received alfuzosin, Group 3 received doxazosin and Group 4 received terazosin. The subjects were prescribed diclofenac injection (75 mg) intramuscularly on demand for pain relief and were followed-up after two weeks with x-rays of the kidneys, ureters, bladder and urinary ultrasonography every week. The number of pain episodes, analgesic dosage and the number of days of spontaneous passage of the calculi through the ureter were also recorded. RESULTS: The average stone size for groups 1, 2, 3 and 4 was comparable (6.13, 5.83, 5.59 and 5.48 mm respectively). Stone expulsion was observed in 11%, 52.9%, 62%, and 46% in groups 1, 2, 3 and 4 respectively. The average time to expulsion was 10.55 ± 6.21 days in group 1, 7.38 ± 5.55 days in group 2, 7.85 ± 5.11 days in group 3 and 7.45 ± 5.32 days in group 4. Alpha blockers were found to be superior to HBB (p < 0.05). CONCLUSIONS: Medical treatment of distal ureteral calculi with alfuzosin, doxazosin and terazosin resulted in a signi?cantly increased stone-expulsion rate and decreased expulsion time when compared with HBB. HBB seems to have a negative effect on stone-expulsion rate.

PURPOSE: To investigate whether the use of a disposable needle guide results in a decreased incidence of infectious complication after transrectal prostate needle biopsy (TPNB). MATERIALS AND METHODS: Fifty five patients who underwent 10-core TPNB were randomized into two groups. A pre-biopsy blood and urine examination was performed in both groups. Group 1 (25 patients) underwent biopsy with disposable biopsy needle guide and Group 2 (30 patients) underwent biopsy with reusable biopsy needle guide. All patients had a blood and negative urine culture before the procedure. The patients received ciprofloxacin 500 mg twice a day beginning the day before the biopsy and continued for 3 days after. Serum C-reactive protein levels and urine and blood specimens were obtained 48h after the biopsy. Primary endpoint of the study was to determine the effect of needle guide on the bacteriologic urinary tract infection (UTI) rate and secondary end point was to determine symptomatic UTI. RESULTS: The mean age of the patients was 63.46 (range 55 to 68) years. There were no significant differences regarding the prostate-specific antigen level, prostate size, existence of comorbidity in two groups before the procedure. Bacteriologic and symptomatic UTI was detected in 4% vs. 6.6% and 4% vs. 3.9% in Group 1 and 2 relatively (P > 0.05). CONCLUSION: The use of a disposable needle guide does not appear to minimize infection risk after TPNB. Large scale and randomized studies are necessary to determine the effect of disposable needle guide on infection rate after TPNB.
