Objective: Testicular torsion causes migration of neutrophils to the ischemic region and formation of free oxygen radicals that have a critical effect on ischemic reperfusion (I/R) injury. Udenafil is a selective, strong, and reversible inhibitor of phosphodiesterase type enzyme. In our study, we evaluate the protective effect of udenafil against reperfusion injury due to I/R.

Aim Of Study: Metabolic syndrome (MetS) is an abnormality that increases the risk of cardiovascular disease and diabetes. In the recent years, studies showed that MetS is associated with increased risk of incidence, aggressiveness, and mortality of prostate cancer (PCa). We examined the influence of MetS at final pathology in Turkish patients with PCa.

Renal cell carcinomas (RCCs) account 80-85% of all primary renal neoplasms and originate from the renal cortex. The patients who underwent radical or partial nephrectomy for renal tumour in our unit between January 2005 and 2015 were evaluated retrospectively. The patients were divided into two groups; group 1 includes patients who were treated between January 2005 and December 2009, group 2 those from January 2010 to 2015.

Objective: We aimed to determine predictive values of extracapsular extension (ECE) in patients who had undergone radical retropubic prostatectomy (RRP) with prostate-specific antigen (PSA) values below 10 ng/mL.

Material And Methods: We retrospectively scanned data of 167 patients with PSA values below 10 ng/mL who had undergone radical retropubic prostatectomy (RRP) between April 2004 and August 2011 in our clinic. Age, PSA, PSA ratio, PSA density, digital rectal examination (DRE) findings, biopsy total Gleason score, perineural invasion (PNI), and lymphovascular invasion (LVI) were analyzed.

Article Synopsis
  • Varicocele is a condition characterized by enlarged veins in the pampiniform plexus, commonly found in men experiencing infertility, and this study investigates its impact on sperm DNA damage in rats.
  • The experiment involved 30 rats split into three groups: a control group, a group with induced varicocele, and a group that had varicocele corrected through surgery (varicocelectomy), with sperm DNA fragmentation assessed using a specific kit.
  • Results showed that sperm DNA damage was significantly higher in the varicocele group compared to the control, but reduced in the group that underwent varicocelectomy, indicating that surgery can mitigate the DNA damage caused by varicocele.
