Objective: In this study, the adequacy of technical equipment used in the treatment of renal stone along with treatment approaches was evaluated. Materials and methods: Between January 2010 and June 2010, 106 urology residents and specialists practicing in 10 different urology departments of training hospitals in İstanbul were asked to fill a questionnaire to evaluate the adequacy of necessary equipment and the treatment approaches for the treatment of renal stone. Results: Eighty percent of the physicians who participated in the study treated at least 8 patients with renal stone per month. While all participating clinics had rigid . . .nephro-scope, flexible ureterorenoscopy and electroshock wave lithotriptor were available in 41% and 49% of the clinics, respectively. The preferred radiologic evaluation before percutaneous nephrolithotomy (PNL) was intravenous pyelography, and abdominopelvic computed tomography in 72% and 69%, respectively. Tubeless PNL was not preferred by 71% of the participants. The first choice of treatment for coraliform stone was PNL and open surgery in 71% and 26% of participants, respectively. Fifty-four percent of the participants stated that PNL was applied for patients older than 12 years old. Retrograde intrarenal surgery was suggested by 26% of the participants for the treatment of symptomatic lower calix stone. Conclusion: It is encouraging that PNL application is performed in all clinics involved in this study, however, training hospitals should be more equipped Daha fazlası Daha az

Introduction: Glycosaminogylicans (GAG) play as a promotor and inhibitor in some phases of stone formation. Sialic acid (SA) is a low-molecular weight aminosaccaride and found in the molecular structure of GAG and on the surface of many cells. Plasma SA level increases in inflamatory diseases, glomerulonephritis and metabolic abnormalities. Unfortunately, there are only a few studies investigating the relationship between SA level in urine and urological diseases. In this study, the relationship between calcium oxalate crystalization and free, total and complex sialic acid levels in urine and plasma has been investigated. Additional . . .ly, possible effect of potassium citrate on this relationship was also studied. Material and Methods: Thirty wistar female rats were included in this study. They were randomly divided in three groups. 0.12 ml of %5 ethylene glycole was dissolved in water and given to the rats in group 1 by feeding tube two times a day and every other day 0.5 microgram vitamin D3 was added to their drinking water to expose them hyperoxlacuric and hypercalciuric, respectively. Rats in group 2 were exposed to the same procedure as group1. Additionally, 5 mg/day K-Citrat was added to their diet. No special diet program was applied in group 3 (control group). At the end of 30 days, 24 hours urine samples were collected by using metabolic cages and blood samples were taken from each rat. Free and total SA levels were calculated by the technique of measuring thiobarbituric acid as mmol/liter (Warren's method). One way ANOVA test was applied for statistical analysis. Result: Calcium levels measured in plasma and urine were higher in group 1 and 2 than the control group. Similarly, oxalate levels in urine were also higher in group 1 and group 2., The differences were statistically significant when compared with the control group ( Daha fazlası Daha az

Urological risk factors for premature ejaculation

Koyuncu, H. | Şerefoglu, E.C.

Review | 2012 | Turk Uroloji Dergisi38 ( 1 ) , pp.36 - 39

Premature ejaculation (PE) is considered the most common form of male sexual dysfunction, and the prevalence of PE complaints range from 20% to 40% among sexually active men. Acquired PE, which occurs due to an underlying organic and/or psychological cause, may be a treatable condition. Recent evidence has suggested that certain medical conditions such as hyperthyroidism may cause PE. In addition to hyperthyroidism, the literature has also revealed several urologic risk factors that may predispose a man to acquired PE; these include erectile dysfunction, prostatic diseases and chronic pelvic pain syndrome, varicocele, monosymptomati . . .c enuresis and circumcision. This review aims to provide a systematic analysis of the literature regarding these urological risk factors of acquired PE. © 2012 by Turkish Association of Urology Daha fazlası Daha az

Objective: The prevalence of urinary system stone disease is 1-13% worldwide with a steady increase parallel to the increasing modern life style. Turkey is among the countries where the disease is endemic. In this study adequacy of technical equipment used in diagnosis and treatment of ureteral stone along with treatment approaches were evaluated. Materials and methods: A total of 106 urology residents and specialists practicing in 10 different urology departments of training hospitals in Istanbul were asked to fill a questionnaire to evaluate the adequacy of necessary equipment and the treatment approaches in terms of diagnosis and . . . treatment of ureteral calculi. Results: More than 6 patients per month have been evaluated by the 78% of physicians participated to the study. All physicians had rigid ureterorenoscope and pneumatic lithotriptor in their clinics. While plain radiography of urinary system was the inital imaging choice for 63% of these physicians for patients with renal colic; 14% of them stated that they have to use a different imaging technique other than they aimed due to technical availability. For medical expulsive treatment 90% of the doctors were using alpha-blockers among which tamsulosin was the most commonly preferred one. Conclusion: Technical systems necessary for an efficient ureteral stone management seems to be adequate in clinics of physicians involved in this study. Answers given to questions regarding the diagnosis and treatment of ureteral stones were generally compatible with the existing literature data Daha fazlası Daha az

Objective: The aim of this study was to determine the effect of indomethacin, an anti-inflammatory agent, on apoptosis and crystal deposition developing as a consequence of tubular cell injury induced by hyperoxaluria in an animal model. Materials and methods: Fifty New Zealand rabbits were divided into 3 groups. The first 2 groups were fed with hyperoxaluric diet and Group 3 was the control group with no supplementary procedure or treatment. While the animals in Group 1 were given only hyperoxaluric diet, Group 2 animals was applied indomethacin in addition to the hyperoxaluric diet. Animals were sacrificed at the early (7th day) a . . .nd late (28th day) periods and renal tis-sue specimens were sent for the pathological analysis of crystal deposition and apoptosis. Results: The presence and degree of crystal deposition were significantly less in the specimens obtained from indomethacin-treated group during both the early and late periods ( Daha fazlası Daha az
