Introduction: Premature ejaculation (PE) is a frequently encountered sexual dysfunction in men. It significantly impairs quality of life of the affected male and his partner. The aim of this study is to investigate the role of hormonal factors in patients with PE., Patients and Methods: 107 male patients aged between 26 and 64 years (mean 45.1 ± 10.36) who consulted our outpatient clinics with complaints of PE and 94 healthy males (48.1 ± 11.81 years) as a control group were included in the study., Results: When mean serum hormone concentrations of both groups were compared, levels of prolactin and free T4 were found to be significantly higher in the PE group relative to the control group (p < 0.05). At least one of the hormonal parameters was abnormal in 36 cases (33.6%) with PE, compared to only 22 (23.4%) of the controls. The number of hyperprolactinemic cases was found to be significantly increased in the PE group (p < 0.05)., Conclusion: We feel that during the evaluation of this problem, which affects great numbers of men and their partners throughout the world, consideration of potential effects of hormonal factors might be beneficial., (Copyright © 2012 S.

Aim: To study the prevalence of nocturnal enuresis and the impact of associated familial factors in Turkish children with a different socioeconomic status., Methods: A specific questionnaire was distributed to 3,000 parents of primary school children (6-12 years old). Of these children, 1,500 attended primary schools in Umraniye, a suburban region of Istanbul (group 1), and the other 1,500 children visited schools in Suadiye, a well-developed part of Istanbul (group 2). The first part of the survey investigated the familial conditions of the children (financial status, family history of enuresis, and family size). The second part of the questionnaire surveyed the demographic and physical characteristics of the children. The last part was designed to investigate the opinions and beliefs of the parents about nocturnal enuresis and treatment modalities. The prevalence rates of nocturnal enuresis and associated familial factors of these children from two different regions of Istanbul were compared., Results: Of the 3,000 questionnaires distributed, 2,589 (86.3%) were returned and included in the final analysis. The mean age of group 1 and 2 children was 8.88 +/- 1.4 and 8.9 +/- 1.5 years, respectively (p > 0.05). The gender of the subjects was equally distributed (48.6% males and 51.4% females). Enuresis was present in 334 children (25.5%) of group 1 and in 205 children (16%) of group 2. Enuresis was significantly more common in group 1 (p < 0.01). The families consisted of 4.69 +/- 1.4 and 4.1 +/- 1.1 persons, respectively (p < 0.01). A yearly income of USD 7,000 was achieved in group 2 by 54%, in group 1 by only 0.7% (p < 0.01). Only 26 children of group 1 (7.8%) and 22 children of group 2 (10.8%) were noted to receive medical enuresis treatments, with no statistically significant difference between the groups (p > 0.01). The parents of the enuretic children from the suburban region of Istanbul were found to consider the condition a normal developmental entity. They believed that enuresis will resolve spontaneously and that no treatment is necessary. On the contrary, the parents of the enuretic children in the well-developed region of the city believed that enuresis is a psychological problem and that intensive psychological assistance is essential for the management., Conclusions: Our study indicates that the prevalence of nocturnal enuresis in Turkey is comparable to that reported in the literature. The parents consider that enuresis nocturna is not a fatal disorder, that the drugs used in the treatment may be harmful, and that no medical assistance is required. Trained health personnel and physicians should inform the parents about enuresis in order to prevent possible behavioral and self-esteem problems., (2008 S. Karger AG, Basel.)

Aim: To evaluate the risk of bacteriuria after transurethral resection of the prostate and the preventive effects of different kinds of antibiotics., Patients and Methods: Urine was collected for culturing 1 week before the operation and on postoperative days 2 and 10. The patients were divided into four groups: group 1 patients were given a first-generation cephalosporin (cefazolin 1 g), group 2 patients received a second-generation cephalosporin (cefuroxime 750 mg), group 3 patients were given a third-generation cephalosporin (ceftazidime 1 g), and group 4 patients received a placebo., Results: The 2nd-day postoperative bacteriuria rates were similar in all groups. On the 10th day, the incidence rates of bacteriuria in group 4 and group 1 patients were 40 and 31%, respectively (p = 0.661). In group 2, the bacteriuria incidence rate was 6.6%, and when compared with the placebo group, the difference was considered significant (p = 0.002). The difference between group 3 and group 4 was also significant (p = 0.003). There were statistically significant differences between group 1 and group 2 (p = 0.008) and between group 1 and group 3 (p = 0.01)., Conclusions: Our study demonstrated that postoperative bacteriuria incidence rates are high, even in patients who underwent transurethral resection of the prostate with sterile urine, but it can be reduced by using antibiotic prophylaxis with cefuroxime or ceftazidime.

The urinary flow patterns and the Toguri nomogram were compared in the intermediate functional results of the tubularized-incised plate urethroplasty (TIPU) to repair distal and midpenile hypospadias by using uroflowmetry. 28 children who were toilet trained, were able to void volitionally, and had no fistulas following hypospadias repair were eligible for the study. The study did not include children who had persistent fistula, meatal stenosis or urethral stricture, and did not return for follow-up. The mean age was 8.4 years and the mean follow-up period was 18 months. The urinary flow pattern, maximum (Q(max)) and average flow rate (Q(ave)) were measured; the results were expressed as percentiles and compared to the Toguri values from normal children. The Q(max) and Q(ave) were considered normal if they were in >25th percentile, equivocally obstructed in the 5-25th percentile and obstructed if <5th percentile. The flow pattern was classified as bell ring shape, plateau or intermittent. According to the Toguri nomogram, 22 of 28 patients (78.5%) were considered normal, 4 patients (14.2%) as equivocally obstructed, and 2 patients (7.1%) as obstructed group. A normal bell-shaped flow curve was obtained in 23 (82.1%) of the children. 4 patients (14.2%) had a plateau flow pattern. Only 1 of the patients had an intermittent shape flow curve. The flow pattern was normal bell-shaped for all of the patients, except 1, with Q(max) above the 25th percentile according to the Toguri nomogram. Of children with Q(max) below the 5th percentile, both of them had a plateau flow pattern and were found to have an asymptomatic meatal stenosis, which was improved with urethral dilatation. However, of the 4 patients with Q(max) between 5 and 25 percentiles, 2 had a plateau flow pattern and the others had a bell-shaped flow pattern. The flow patterns of the 2 patients determined as obstructive by the Toguri nomogram were plateau-shaped. TIPU provides satisfactory functional results for distal and midpenile hypospadias; uroflowmetry is an important noninvasive tool to evaluate this technique. There are no studies in the literature which only used flow patterns for the evaluation of urination for follow-up after the hypospadias repair. Our study showed that the evaluation of obstruction according to the Toguri nomogram may not be necessary in patients with a normal bell-shaped flow pattern in uroflowmetry., (Copyright 2007 S.

Objectives: It is not yet certain whether early hormonal treatment in cryptorchidism is safe for germ cells. We investigated the histologic effects of human chorionic gonadotropin (hCG) therapy on descended testes of rats., Design and Setting: Thirty male Wistar albino rats were randomized into two groups. The rats of the hCG group (n=15) were administered 50 IU/kg/day hCG once daily via the subcutaneous route for 15 days. Fifteen rats received subcutaneous isotonic saline and acted as controls. At the first month, testicular tissue was obtained after scarification in both groups. The histological examination was performed to evaluate the seminiferous tubular diameter, germinal membrane thickness, and the percentage of the open seminiferous tubule lumen in each testis to compare the two groups., Results: The percentage of the open seminiferous tubular lumen in testicular tissues of hCG-treated rats was higher than that of controls (p<0.05). The mean germinal membrane thickness in testicular tissues of the hCG group was statistically lower than that of the control group (p<0.05). There was no statistical difference between mean seminiferous tubular diameter in testicular tissues of hCG-treated rats and controls, as expected (p>0.05). Additionally, there were two interesting cases of Sertoli cell only appearance in the hCG group., Conclusions: We may assume that hCG impairs the seminiferous tubule histology in normal testes of rats. Thus, further experimental studies on dose dependency and the reversibility of these effects are warranted., (Copyright (c) 2006 S. Karger AG, Basel.)

Although hydatid disease may affect any organ of the body, there are only a limited number of cases where the primary lesion is in the retroperitoneal region. Since the clinical and laboratory findings are nonspecific, the correct preoperative diagnosis may be difficult. A primary retroperitoneal hydatid cyst that was given a preoperative diagnosis of adrenal mass and treated by adrenalectomy and partial nephrectomy is presented and discussed with the relevant literature., (Copyright 2004 S.
