OBJECTIVES To compare the effectiveness of macroplastique injection with artificial urinary sphincter implantation (AUS) for treatment of postprostatectomy incontinence (PPI). METHODS A prospective randomized clinical trial including 45 patients with PPI was performed secondary to radical retropubic prostatectomy (RRP), transvesical prostatectomy (TVP),(More)
OBJECTIVE The purpose of this study was to investigate the incidence of the retroaortic left renal vein (RLRV) in patients with varicocele. METHODS The left renal vein was ultrasonographically investigated for the presence of the RLRV in 140 patients with varicocele and a control group of 137 age-matched patients. The main diagnostic criteria for(More)
The changes in serum prostate-specific antigen (PSA) concentrations can be used as a prognostic factor in patients undergoing maximum androgen blockage for metastatic prostate cancer. A total of 149 patients followed in our department were classified into 4 groups on the basis of PSA changes: group 1, those with normalisation of PSA levels within the first(More)
BACKGROUND AND PURPOSE Endoscopic subureteral injection of tissue-augmenting substances has become an alternative to antibiotic prophylaxis and open surgery for the management of vesicoureteral reflux (VUR). Several injectable materials have been tried for this purpose. In this study, we tried to determine the efficacy of dextranomer/hyaluronic acid(More)
Testicular torsion causes an enhanced formation of reactive oxygen species which contributes to the pathophysiology of ischemia-reperfusion injury in the testis. We evaluated here the effect of caffeic acid phenethyl ester (CAPE), a new antioxidant and anti-inflammatory agent on histopathological changes in testicular ischemia-reperfusion injury. Adult male(More)
We compared three different chemotherapy regimens containing epirubicin in hormone-refractory prostate cancer (HRPC) patients. Sixty-nine patients with HRPC were randomized into three groups. The first group (22 patients) received 30 mg/m2/week i.v. epirubicin for 8 weeks. The second group (24 patients) received 30 mg/m2/week i.v. epirubicin for 8 weeks(More)
We investigated the possible relationship between body mass index (BMI) score and varicocele recurrence in an infertile patient population. A total of 255 primary infertile male patients (138 with varicocele and 117 for control) were included in this study. Height and weight measurements, clinical examination for varicocele, determination of serum hormone(More)
Introduction The changes in serum prostate specific antigen (PSA) concentrations can be used as a prognostic factor in patients undergoing maximum androgen blockade for metastatic prostate cancer. Material and method A total of 149 patients followed up in our department were classified into 4 groups on the basis of PSA changes: group 1; those with(More)
INTRODUCTION To evaluate the effects of periprostatic bupivacaine administration on pain control and analgesic consumption after transurethral prostate resection (TURP). MATERIALS AND METHODS The study included 40 male patients with benign prostatic hyperplasia who underwent TURP, and they were divided randomly into two groups. All patients were operated(More)
operation techiniques have been described for the surgical treatment of primary hypospadias. The objective to be attained in all these methods is to ensure the formation of a functionally normal urethra and a cosmetically acceptable penis. Functional integrity was used to be important in the first years of hypospadias surgery which was then popular (1).(More)
