Seminal plasma cytokine levels in the diagnosis of chronic pelvic pain syndrome

Abstract Background: Chronic non‐bacterial prostatitis/chronic pelvic pain syndrome (CPPS) are frequently encountered clinical entities characterized by painful and irritative voiding symptoms often referable to the prostate. Diagnosis usually depends on the symptoms and treatment mainly consists of reassurance, anti‐inflammatory medications and antibiotics in the absence of a documented infection. To have objective diagnostic criteria, we determined the possible roles and diagnostic efficacies of soluble cytokines interleukin‐1β (IL‐1β), tumor necrosis factor‐α (TNF‐α), IL‐2R, IL‐6 and IL‐8 in the seminal plasma of patients with different forms of CPPS.

Prevalence of the Complaint of Ejaculating Prematurely and the Four Premature Ejaculation Syndromes: Results from the Turkish Society of Andrology Sexual Health Survey

INTRODUCTION In addition to the previously known lifelong and acquired premature ejaculation (PE) syndromes, the existence of two more PE syndromes has been suggested: natural variable PE and premature-like ejaculatory dysfunction. However, epidemiological studies investigating the prevalence of these four PE syndromes have yet to be conducted. AIM To determine the prevalence of the complaint of ejaculating prematurely across the four PE syndromes. METHODS This study, conducted between June 2009 and December 2009, was designed as a non-interventional, observational cross-sectional field survey. Participating couples were randomly selected from 17 provinces of Turkey. All participants were asked to complete a questionnaire including data regarding demographics, socioeconomic status, social and cultural factors, medical and sexual history, current medications, and ejaculation time. Subjects with a complaint of ejaculating prematurely were classified as lifelong, acquired, and natural variable PE, or premature-like ejaculatory dysfunction. MAIN OUTCOME MEASURES The main outcome measures were prevalence of complaint of ejaculating prematurely in the general population and across the four PE syndromes. RESULTS A total of 2,593 couples (mean age, 41.9±12.7 years for males and 38.2±12.1 years for females) were enrolled. Five-hundred twelve subjects (20.0%) complained of ejaculating prematurely. Fifty-eight (2.3%), 100 (3.9%), 215 (8.5%), and 131 (5.1%) subjects were classified as lifelong, acquired, and natural variable PE, and premature-like ejaculatory dysfunction, respectively. CONCLUSIONS The prevalence of the complaint of ejaculating prematurely among Turkish men was 20.0%, with the highest PE syndrome being natural variable PE (8.5%) and premature-like ejaculatory dysfunction (5.1%).

Detection of Bladder Tumors With 3-Dimensional Sonography and Virtual Sonographic Cystoscopy

Bladder tumors are among the most common types of malignant neoplasms of the urinary tract. The purpose of this study was to evaluate the potential value of 3‐dimensional (3D) sonography and sonographic cystoscopy in detection of bladder tumors.

Role of Diffusion MRI and Apparent Diffusion Coefficient Measurement in the Diagnosis, Staging and Pathological Classification of Bladder Tumors

Objectives: Our aim was to investigate the role of simultaneous apparent diffusion coefficient (ADC) measurement and diffusion-weighted MRI (DWMRI) in the diagnosis and differentiation of bladder masses. Methods: Weexamined 45 patients presenting with hematuria by dynamic and diffusion MRI (at b100, b600, b1000 gradients) and cystoscopy. Thirty healthy volunteers without hematuria were also included in the study. Results from imaging techniques were compared to cystoscopic and histopathologic findings. The ADC values of benign and malignant bladder masses, and bladder tissue in healthy subjects were measured and compared with each other. Results: The mean ADC values of benign (n = 10) and malignant lesions (n = 35) were significantly lower than the mean ADC values of adjacent bladder walls and bladder walls of healthy subjects at all 3 gradients (p < 0.05). However, no significant difference was detected between benign and malignant lesions (p > 0.05). Mean ADC values of invasive tumors were significantly lower than superficial malignancies at b600 and b1000 gradients. The mean ADC values of transitional cell tumors were significantly higher than squamous cell tumors at b100 and b600 gradients. Conclusion: Simultaneous measurement ofADC and DWMRI provided useful information in the diagnosis, staging and histopathological classification of bladder tumors.

COMPARISON OF TWO DIFFERENT MICROSURGICAL METHODS IN THE TREATMENT OF VARICOCELE

We reviewed records from patients who underwent two different microsurgical varicocelectomy methods: 147 (high inguinal (MHIV) and 65 sub-inguinal (MSIV) microsurgery) to compare the therapeutic activity and complications. Patients who had 2 different microsurgical varicocelectomies were compared according to preoperative connected vein, number of designated arteries, postoperative semen and improvement degree in hormone parameters, increased ratio related with pregnancy and complications. The ratio of improvement of postoperative semen parameters in patients where MHIV and MSIV were performed was, 42% and 38% (p > 0.05). Pregnancy was achieved in MHIV at a ratio of 41% (34/82) and 33% (22/65) in MSIV (p > 0.05). There was no significant difference according to mean operation periods, the vein connected between the groups. The number of testicular arteries were significantly higher than the ones in MHIV (p < 0.01). However, as a postoperative complication, hydrocele was not seen in any of the patients, while relapses occurred in 1 MHIV and 2 MSIV patients. MHIV and MSIV techniques are effective methods to treat varicocele. However, the excess number of connected veins due to the anatomic feature of MSIV increases the possibility of relapses and the technical difficulty during surgical intervention.

Pseudoaneurysm and renal arteriovenous fistula after nephrectomy: two cases treated by transcatheter coil embolization

Pseudoaneurysms and arteriovenous fistulas of renal arteries are rare clinical lesions. Invasive renal procedures may lead to pseudoaneurysm or arteriovenous fistulas (AVFs). We report two pseudoaneurysms and arteriovenous fistula cases that were treated by transcatheter embolization with metallic coils. The first case is left main renal artery pseudoaneurysm after nephrectomy in a patient with a solid renal tumor. The second case is right main renal artery AVF with giant pseudoaneurysm after both gunshot injury and nephrectomy. On the basis of color Doppler sonography and computed tomography (CT) findings, cases were diagnosed as pseudoaneurysm after nefrectomy. Contrast-enhanced CT scans showed a hyperdense area within the hematoma consistent with pseudoaneurysm. Endovascular treatment with coil embolization succeeds to total occlusion in renal artery pseudoaneurysm. Delayed hemorrhage related to postnephrectomy may be life-threatening conditions because of diagnostic difficulties. AVF and pseudoaneurysm can be treated safely and successfully by transcatheter arterial embolization.

Infertility treatment in autosomal dominant polycystic kidney disease (ADPKD) – a case report

Autosomal dominant polycystic kidney disease (ADPKD) is a frequently occurring inherited condition with cysts in many organs including the kidneys. However, a combination of seminal vesicle cysts, cystic obstruction of ejaculatory duct and ADPKD is rarely encountered. The following case report presents an infertile ADPKD patient who had seminal vesicle cysts and ejaculatory duct cyst, and describes the treatment by transurethral resection of the ejaculatory duct.

Utility of ADC measurement on diffusion-weighted MRI in differentiation of prostate cancer, normal prostate and prostatitis

To determine the utility of apparent diffusion coefficient (ADC) values in differentiation of prostate cancer from normal prostate parenchyma and prostatitis we obtained ADC values of 50 patients at b 100, 600 and 1,000 s/mm(2) diffusion gradients. The ADC values of prostate cancer group were significantly lower than normal prostate and prostatitis group at b 600 and 1,000 s/mm(2) gradients. The ADC values at high diffusion gradients may be used in differentiation prostate cancer from normal prostate and prostatitis.

Prevalence of sexual dysfunction and urinary incontinence and associated risk factors in Turkish women

OBJECTIVES Female sexual dysfunction (FSD) and urinary incontinence (UI) are associated risk factors that might cause each other. No study has investigated prevalence of FSD and UI in the same population. The aims of the study were to investigate the prevalence of FSD and UI and associated risk factors in the same population. STUDY DESIGN The study included 1217 women in 20 provinces, representing the geographical regions of Turkey. Women aged ≥18 years with active sexual life in the last 6 months were enrolled. FSD, overactive bladder, UI, depression, and sexual distress were investigated using validated scales. Risk factors that might predict FSD and UI were determined in the same population. RESULTS The prevalence of FSD and UI was 52.5% and 14.6%, respectively. Comparing the women with and without FSD, those with FSD were older, had higher body mass index (BMI), less physical exercise, older spouses, lower educational level, and lower rates of smoking and alcohol consumption. The rates of women in menopause and those with a spouse/partner having erection problem and the rates of UI, depression, and sexual distress were higher in the FSD group. Age of spouse, low educational level, not smoking, not consuming alcohol, menopause, not giving consent to spouse/partner to use sexual performance-enhancing drugs when necessary, depression, and sexual distress were the significant risk factors for FSD. Of the women with UI, 56% had overactive bladder symptoms, 32% had stress UI, and 12% had mixed type UI. Comparing the women with and without UI, those with UI were older, had higher BMI, lower educational level, and older spouses. The rate of menopausal women and the rates of FSD, depression, and sexual distress were higher in the UI group. Menopause and FSD were the significant risk factors for UI. CONCLUSIONS This is the first study to investigate prevalence of FSD and UI in the same population. UI deteriorates sexual functions of women. Therefore, both conditions should be assessed when women complain of either sexual or urinary problems.
