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.

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.

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.

Technetium Tc 99m Sulphur Colloid Seminal Vesicle Scintigraphy: A Novel Approach for the Diagnosis of the Ejaculatory Duct Obstruction

OBJECTIVES To define a novel technique in the diagnosis of partial and complete ejaculatory duct obstruction (EDO). METHODS Twenty men with suspected EDO were initially evaluated by transrectal ultrasound (TRUS). Subsequently, all patients underwent TRUS-guided seminal vesicle (SV) scintigraphy. Technetium Tc 99m sulphur colloid solution was injected into each SV under TRUS guidance and patients were immediately evaluated by scintigraphy. After patients ejaculated scintigraphy was repeated. The difference between 2 measurements in respect to technetium Tc 99m count was used to measure the percentage of emptying. RESULTS In the first group, TRUS revealed 11 patients with findings suggestive of EDO, whereas no abnormality was found in 9. Scintigraphic measurement in first group of patients showed a mean emptying ratio for the right and left SVs of 16.6% +/- 2.22 (2.2 to 30.6) and 17.1% +/- 2.34 (1.4 to 32.5), respectively. The mean percent of emptied technetium Tc 99m from right and left SVs in patients with no pathologic findings on TRUS was 30.9% +/- 4.3 (10.1 to 44.2) and 33.9% +/- 5.81 (13.6 to 68.1), respectively. Statistically significant difference was determined between 2 groups (P = 0.037). Initially, TRUS examination revealed no pathologic findings in 3 patients; however, SV scintigraphy showed less than 30% emptying and revealed an additional 33% of patients to be obstructed in our series. CONCLUSIONS TRUS, the static anatomic imaging modality, may not be sufficient to distinguish functional from complete obstruction. Seminal vesicle scintigraphy is unique that incorporates physiologic aspect of ejaculation into a diagnostic intervention, of which we believe that is especially important in diagnosis of functional EDO.

Scrotal ultrasonography: should it be used in routine evaluation of infertile men?

Several studies have suggested that male infertility and testicular cancer may have common aetiological factors. Scrotal ultrasonography (US) has an important role in the diagnosis of testicular tumours when not palpable by physical examination. In this study, we present two infertile men referred to our clinic. Patients were evaluated by a detailed physical examination, semen analyses and hormonal assessment. Both patients underwent scrotal US examination. Semen analysis of the patients revealed oligoasthenospermia in both patients. Scrotal US revealed hypoechoic masses in the left and right testes of both patients, which were nonpalpable by physical examination. Scrotal exploration and subsequent orchidectomy were performed. Histopathological examination revealed mixed germ cell tumour and Sertoli–Leydig cell tumour in case 1 and case 2 respectively. With these cases, we discussed the role of scrotal US in the routine diagnostic evaluation of infertile men.
