Spontaneous Rupture of Proximal Ureter: A Case Report

Spontaneous non-traumatic urinary collecting system ruptures without distal obstructive causes are rare and uncommon. They should be considered in the differential diagnosis of renal colic or acute abdomen. Here, we present a case of spontaneous rupture of the left proximal ureter with perirenal fluid extravasation without an identified cause. The patient was treated conservatively and in the first week, symptom improvement was shown by control imaging methods. Ureteral stent placement or percutaneous nephrostomy, even open surgery are options for the management of spontaneous rupture of the urinary collecting system, however, conservative management may be an option for selected patients

Investigation the effect of propranolol, metoprolol and carvedilol on spermatogenesis in rat testis

Background: Coronary arterial diseases are one of the increasing disease around the worldwide. Because of common using of the beta blockers, we aimed to investigate the effect of different beta-adrenergic receptor blockers on spermatogenesis in male rats.Methods: Adult male Sprague Dawley rats were obtained. Totally 32 rats homogenized according to their weight and divided into four groups that each one includes eight rats. Three of groups were determined as drug groups and remained groups were determined as a control group. Propranolol 40mg/kg, Metoprolol succinate 60mg/kg, Carvedilol 30mg/kg dosage was given by oral gavage within the saline solution, and the only saline solution was given to control group for 21 days, respectively. After 21 days rats were sacrificed, and testis were extracted. Then, histopathologic evaluation was performed.Results: There was statistical significance both right and left testis volume of experimental between control and carvedilol groups (p<0.05). There was statistical histopathological significance between control and carvedilol (p<0.05), control and propranolol (p<0.05), metoprolol succinate and propranolol (p<0.05), metoprolol succinate and carvedilol groups (p<0.05), respectively.Conclusions: Beta-adrenergic receptor blockers have adverse effects on spermatogenesis. Especially propranolol and carvedilol that were non-selective, effects spermatogenesis worse than selective beta blockers such as metoprolol succinate. Extensive use of these drugs may affect spermatogenesis in male, so male patients who have a complaint of infertility should be questioned regarding the use of beta blockers

Alleviating Effect of Alpha-Pinene on Testicular Torsion and Detorsion Injury in Rats

Objective:It was aimed to evaluate whether alpha-pinene (AP) had a beneficial effect in the testicular ischemia/reperfusion injury (IRI) model for the first time.Materials and Methods:Testicular malondialdehyde, total oxidant status, and total antioxidant status levels were determined using spectrophotometric methods. The superoxide dismutase (SOD), glutathione (GSH), glutathione peroxidase (GPx), myeloperoxidase (MPO), 78-kDa glucose-regulated protein (GRP78), activating transcription factor 6 (ATF6), and C/EBP homologous protein (CHOP) levels were determined using the commercial enzyme-linked immunosorbent assay kits. Hematoxylin-eosin staining method was used in the histopathological evaluation.Results:In the IRI group, testicular MDA, MPO, GRP78, ATF6, and CHOP levels were significantly increased, while GSH and GPx levels were decreased compared with the control group (p<0.01). AP application restored these levels significantly (p<0.05). Johnsen scores were also significantly lower in the IRI group compared the control group (p<0.001), and AP treatment increased these scores significantly (p<0.001).Conclusion:These results suggest that AP can protect the testicular tissue against IRI by inhibiting oxidative stress, inflammation, and endoplasmic reticulum stress with its antioxidant properties, thus providing a molecular basis for a novel medical treatment of testicular IRI. Future studies are needed on other mechanisms of the protective effect of AP on the pathogenesis of testicular torsion

Prevalence of Poor Sleep Quality and Its Determinants Among Men Suffering from Erectile Dysfunction

Objective:Recent findings implicate a higher prevalence of erectile dysfunction (ED) among men with sleep disorders. We investigated sleep quality among men with ED.Materials and Methods:A prospective study was conducted at 12 different andrology outpatient clinics among men with complaints of insufficient erections. The subjective quality of sleep was measured using the Pittsburgh Sleep Quality Inventory. Erectile function and its dimensions were measured using the International Index of Erectile Function (IIEF) questionnaire. The age-adjusted Charlson comorbidity index and Beck Depression Inventory were used to evaluate interrelations with comorbid disease severity and depression of the subjects consecutively in the study.Results:Among 431 eligible men, the median age of the participants and their erectile function scores in the IIEF were 51 [interquartile range (IQR)=43-59] and 16 (IQR=11-19), respectively. Poor sleep was observed in 192 of 431 (44.5%) subjects. Multivariable analysis revealed that younger age [odds ratio (OR)=0.95, p=0.01], lower body mass (OR=0.86, p=0.01), lower serum high-density lipoprotein cholesterol (OR=0.95, p=0.02), and higher severity of depression (OR=2.1, p=0.0001) were predictors of poor sleep quality among men with ED.Conclusion:Nearly half of the men with ED also suffer from poor sleep. Younger age, lean body mass, and severe depression were the main predictors of poor sleep quality among ED sufferers

A novel prognostic risk factor for patients undergoing radical prostatectomy: Triglyseride-glucose index

Background: Obesity and metabolic syndrome are growing health problems in western countries. Recently reported triglyseride-glucose (TyG) index is a reliable and accessible indicator of metabolic syndrome. TyG index could be used as a indicator of a prognostic risk factor for metabolic syndrome-related cancers. Objectives: To investigate the prognostic role of TyG index on oncological outcomes in patients undergoing radical prostatectomy. Design, Setting and Participants: Data from 200 men who underwent radical prostatectomy were used. Outcome Measurements and Statsitical Analyse: TyG was calculated based on TyG index = Ln [TG (mg/dL) FPG (mg/dL)/2] formula. Patients were divided into two groups according to the 8.55 level as cut-off value for TyG index. Laboratory results, oncological outcomes and survivals were comparised statistically between groups. Results: Mean ages of patients were 64.32 +/- 6.1 years and median follow-up time was 61.6 +/- 35 (range 4-140) month. Biochemical recurrens was observed in 42 (21%) patients. Positive correlation between TyG index, body mass index, waist circumference, prostate biopsy gleason score, clinical T stage, positive surgical margin, pathological T stage and biochemical recurrence were observed. There was no statistical significance in terms of survival between groups. Conclusion: Association between TyG index and prostate cancer may facilitate to predict unfavorable prognostic factors of radical prostatectomy. Increased TyG index may use as a predictive marker of positive surgical margin status before radical prostatectomy, BCR, advanced cT and pT stages after radical prostatectomy or worse biopsy gleason score in clinical practice

Primary renal angiosarcoma: A case report and a short review of literature

Primary renal angiosarcomas (AS) are uncommon tumors with poor prognosis. Aetiology is unknown but some unproven risk factors have been described. It is difficult to discriminate these masses from renal cell carcinomas or other renal masses with imaging modalities. Immunohistochemistry plays an important role in the diagnosis. Main treatment protocol for primary renal AS is still controversial and nephrectomy with chemotherapy and/or radiotherapy seems the only treatment option. We state a primary renal angiosarcoma case for its rareness and contribution to literature

Whortleberry protects kidney against the cisplatin-induced nephrotoxicity: an experimental study

Purpose: This study investigated the antioxidant effects of whortleberry against cisplatin-induced nephrotoxicity in rats. Material and methods: This study included 48 female Sprague–Dawley rats weighing 263.68 ± 8.29 g. The rats were divided into the following six groups, with eight rats in each group: control, ethanol control, whortleberry control, cisplatin control, 16 mg/kg cisplatin +100 mg/kg whortleberry, and 16 mg/kg cisplatin +200 mg/kg whortleberry groups. Biochemical analysis was performed by measuring total oxidant status and total antioxidant status, histopathological analysis was performed by calculating proximal and distal tubule areas (μm2), and immunohistochemical analysis was performed by determining anti-Caspase-3 immunostaining. Differences among the groups were examined using one-way analysis of variance, and p < .05 was considered statistically significant. Results: Cisplatin treatment decreased the total antioxidant status and increased the total oxidant status and Caspase-3 level. Moreover, it resulted in the dilatation, vacuolization and loss of tubular epithelial cells; and glomerular degeneration and edema in the kidney tissues (p < .05). Treatment with 100 and 200 mg whortleberries increased the total antioxidant status; decreased the total oxidant status and Caspase-3 level and ameliorated distal and proximal tubule degeneration, glomerular degeneration and edema in the kidney tissues (p < .05). Conclusions: Our results indicate that the antioxidant effects of the whortleberry decrease cisplatin-associated nephrotoxicity

Astaxanthin Protects Testicular Tissue against Torsion/Detorsion-Induced Injury via Suppressing Endoplasmic Reticulum Stress in Rats

Background The aim of this study was to investigate the effects of astaxanthin (ASX) on testicular torsion/detorsion (T/D) damage in rats in terms of oxidative stress and endoplasmic reticulum (ER) stress. Methods Eighteen male Sprague-Dawley rats were divided into three groups with six rats in each group: control, T/D and T/D + 20 mg/kg ASX. Torsion and detorsion times were applied as 4 h and 2 h, respectively. ASX application was performed 30 minutes before detorsion. At the end of the period, testicular tissues were removed and biochemical and histological analyzes were performed. To evaluate the degree of oxidative stress, tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) were determined using colorimetric methods, while tissue superoxide dismutase (SOD) levels were determined using ELISA kit. To evaluate the degree of ER stress, tissue glucose regulatory protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP) levels were determined using ELISA kits. Johnsen’s testicle scoring system was used for histological evaluation. Results In the T/D group, it is determined that statistically significant decreasing in TAS, SOD levels and Johnsen score, and increasing in TOS, OSI, MDA, GRP78, ATF6 and CHOP levels (p < 0.001) compared with control group. ASX administration statistically significantly restored this T/D-induced damage (p < 0.01). Conclusion This is the first study to show that ASX prevent T/D-induced testicular damage through its antioxidant activity. More comprehensive studies are needed to see the underlying mechanisms

Chlorogenic acid ameliorates torsion/detorsion-induced testicular injury via decreasing endoplasmic reticulum stress

Backround Testicular torsion (TT) is an urological emergency situation especially in adolescents and young men. The main pathophysiology of testicular torsion/detorsion (T/D) is ischemia-reperfusion (I/R) injury. I/R induces the production of reactive oxygen species (ROS) thought to play a critical role in tissue injury. Increasing evidence suggests that ER stress may play an important role in I/R-induced cell death. During ischemia, oxygen and glucose deprivation also causes abnormalities in protein folding processes. Antioxidants suppress oxidative stress directly as well as ER stress and thus gain importance in the treatment of pathologies associated with oxidative stress and ER stress, such as I/R damage. Chlorogenic acid (CGA) which is formed by the esterification of caffeic and quinic acids and is one of the most abundant phenolic acids in nature. There is also a growing body of studies reporting protective effects of CGA against I/R injury in different tissues, including intestinal, heart and brain. Objective To investigate the effects of CGA on oxidative stress and ER stress in an experimental testicular I/R injury model. Design Rats were divided into three groups: control, T/D, and T/D CGA. In the T/D CGA group, 100 mg/kg CGA was given intraperitoneally 30 min before detorsion. While tissue malondialdehyde (MDA) levels were determined manually using a colorimetric method, tissue superoxide dismutase (SOD), 78-kDa glucose regulatory protein (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP) levels were determined enzyme-linked immunosorbent assay (ELISA) kits. Johnsen's testicle scoring system was used for histological evaluation. Results In T/D group, tissue MDA, GRP78, ATF6 and CHOP levels were significantly higher than control group (p < 0.05). These increases were significantly reversed with CGA pre-treatment (p < 0.05). The histopathological Johnsen score was significantly lower in the T/D group compared to the control group, but the level of histopathological Johnsen score was significantly restored by CGA pre-treatment (p < 0.05). Discussion The relationship between I/R injury and ER stress has been emphasized frequently in recent years. This study in which the effects of CGA on TT were examined for the first time, showed that CGA can inhibit I/R-induced testicular damage. Conclusion These results may provide a new insight into CGA and may form the first clinical theoretical basis for the possible use of CGA in the treatment of TT in the future. However, the real function of CGA in TT patients needs further investigation
