Aim: The purpose of this study was to assess the effectiveness of syringic acid in preventing ischemia-reperfusion injury following detorsion in a rat model of induced testicular torsion. Material and methods: In our study, a total of 24 rats, eight in each group, were used. Group 1 served as the control group. Group 2 underwent testicular torsion and detorsion. Group 3 underwent the same procedures as Group 2, but also received 100 mg/kg syringic acid immediately following ischemia. Spectrophotometric analysis was performed on blood samples, and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), as well as the values of malondialdehyde (MDA), were evaluated under direct microscopic examination of the testis to determine tissue injury. The architecture of the seminiferous tubules and spermatogenesis processes were graded using the Johnsen and Cosentino scoring systems. Results: The mean value of MDA was higher in Group 2 compared to the other groups (p < 0.001). Group 3 demonstrated a decline in the concentrations of proinflammatory cytokines, such as tumor necrosis factor-alpha, interleukin-6, and interleukin-1 beta, as indicated by biochemical analysis of blood samples, when compared to Group 2 (p-values: 0.045, 0.001, and <0.001, respectively). In addition, the improvement in Johnsen and Cosentino scores was significantly higher in Group 3 compared to Group 2 (p = 0.028 and p = 0.001, respectively). Conclusion: These findings suggest that syringic acid has a protective effect against testicular oxidative damage.

Purpose The purpose of this research is to examine the impact of syringic acid on ischemia-reperfusion injury in cavernosal tissue, utilizing a rat model of induced priapism. Materials and methods A total of 24 rats were allocated into three groups. Group 1 was designated as the control group, while Group 2 underwent ischemia-reperfusion injury assessment using the priapism model. Group 3 underwent the same procedures as Group 2, with the addition of intraperitoneal administration of syringic acid (100 mg/kg) 60 min after priapism initiation. All rats underwent penectomy, and sufficient blood samples were collected. Histopathological assessment of penile cavernosal tissue involved grading tissue damage, inflammation, vasocongestion, desquamation, and edema on a scale of 0-3 (0: normal, 1: mild, 2: moderate, 3: severe). Result Significant differences were observed among the three groups in terms of IL-1 beta and TNF-alpha levels (p=0.001 and p<0.001, respectively). IL-1 beta and TNF-alpha levels in Group 2 were found to be significantly higher than Group 3 (p=0.003 and p=0.004). There was also a significant difference among the three groups in terms of median MDA levels (p<0.001). Furthermore, the median MDA level in Group 2 was found to be significantly higher than that in Group 3 (p<0.001). While significant differences were observed among the three groups in terms of median SOD and GSH-px levels, no significant difference was found among the groups in terms of median PC levels (p=0.004, p= 0.048, and p=0.159, respectively). In direct microscopic examination, a significant improvement in pathological scores was noted in Group 3 compared to Group 2 (p<0.001). Conclusion Syringic acid demonstrated protective properties against ischemia-reperfusion injury caused by priapism in cavernosal tissue.

Aim: To determine the value of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), systemic immune-inflammation (SII) index and De-Ritis ratio, which are among preoperative whole blood and biochemical parameters, in the diagnosis of testicular tumor. Materials and Methods: The data of patients who underwent inguinal orchiectomy for testicular tumor in our clinic between October 2010 and December 2019 and patients who underwent varicocelectomy, as a control group, were retrospectively analyzed. Patients with missing data, under 18 years of age or with additional morbidity were excluded from the present study. Prediction values for NLR, PLR, LMR, SII index and De-Ritis ratio were determined and the value of these parameters in the diagnosis of testicular tumor was examined. Results: Thirty-four (14.1%) patients underwent inguinal orchiectomy while 207 (85.9%) patients underwent varicocelectomy in the present study. The median age of the patients during surgery was 27 (23-32) years. The number of patients with seminoma, mixt germ cell tumor, yolk sac tumor and embryonal carcinoma was 18 (52.9%), 12 (35.3%), 3 (8.8%) and 1 (2.9%), respectively. It was determined that 61.8% of the patients with testicular tumors were in the T2 stage and 35.3% had metastasis. The cut-off values for NLR, PLR, LMR and SII index were determined as 1.76, 133.43, 7.81 and 571.63, respectively. There was no statistically significant cut-off value for De-Ritis ratio (p = 0.183). The only significant factor for predicting testicular tumor was SII index in multivariate analysis (p <0.001). Conclusion: SII index is a predictive factor that can be used in the diagnosis of testicular tumor.

Introduction: Our century has witnessed a significant increase in obesity, which in its turn, bears several major risks in management of systemic anesthesia. In this context, use of this treatment without general or regional anesthesia is of critical importance for patients under this group. Aim: In present study, it was aimed to analyze the efficacy and safety of holmium laser lithotripsy (HLL) under local anesthesia in obese male patients with bladder stones. Material and Method: In our study, we evaluated a total of 64 obese male patients with body mass index (BMI) ≥ 30 kg/m2, diagnosed with bladder stones and treated HLL under local anesthesia. Demographic data, stone size, operative time, urethral catheterization time and length of hospital stay of the patients were analyzed. Visual Analogue Scale (VAS) scores was calculated for each patient during the procedure. Complications were graded according to modified Clavien classification system. Results: The mean age of patients was 50.58 ± 13.04 years and BMI was 33.46 ± 2.59 kg/m2. Mean stone size was 2.51 ± 1.04 cm and operative time was 43.91 ± 15.92 minutes. None of the patients had severe pain and the mean VAS score was calculated as 2.31 ± 1.02. Mean length of hospital stay was 1.25 ± 1.04 days. Grade 3 or higher complications were not observed according to modified Clavien classification system. Mean urethral catheterization time was 1.56 ± 1.45 days, although varying due to underlying etiological factor. All patients were stone-free and there was a marked improvement in clinical findings. Conclusion: Use of HLL under local anesthesia is a safe and efficacious approach in obese male patients with bladder stone.
