This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

Background/aim: To investigate the relationship between sex-related visceral obesity and WHO/ISUP nuclear grade in clear cell renal cell carcinoma (ccRCC).

Materials And Methods: Between January 2018 and June 2022, 95 patients (56 men and 39 women) with pathologically proven ccRCC who underwent abdominal computed tomography examination were retrospectively examined. The patients were classified into two groups: low- and high-WHO/ISUP nuclear grade ccRCC (n = 58 and n = 37), respectively.

Objective: The aim of this study was to investigate whether urinary glycosaminoglycans (GAG) levels reflect clinical status in men with lower urinary tract symptoms and if they could be used as a marker in management of overactive bladder (OAB).

Methods: A total of 34 patients were recruited who were admitted with LUTS and diagnosed as having clinically bladder outlet obstruction (BOO) due to prostate enlargement. These newly diagnosed, never treated patients underwent routine investigation, consisting of history, physical examination, PSA, ultrasound, uroflowmetry, assessment of symptoms scored by both International Prostate Symptom Score (IPSS) and Marmara- Overactive Bladder Questionnaire (M-OBQ).

Introduction: Herein, we analyzed the histopathological, oncological and functional outcomes of testis-sparing surgery (TSS) in patients with distinct risk for testicular cancer.

Methods: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk testicular germ cell tumor (TGCT) according to the presence/absence of features compatible with testicular dysgenesis syndrome.

Objective: To investigate the effect of SARS CoV-2 on serum total PSA levels in men with BPH diagnosed with COVID-19.

Methods: The PSA (Kit: Immunoassay Program- Cycle 18, Siemens Atellica IM Analyzer) levels in patients who had had a PSA check at least 3 months, but no more than 6 months, prior to diagnosis of acute COVID-19 infection, were examined retrospectively. PSA levels were measured and recorded from these patients on the first day of diagnosis of COVID-19.

Background: A potential role of testosterone among sex hormones has been hypothesized in identifying sex-related differences in the clinical consequences of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Due to the high global prevalence of hypogonadism, the relationship between hypogonadism and SARS-CoV-2 infection outcomes deserves an in-depth study.

Objective: The present study aimed to investigate the relationship of serum testosterone with other laboratory parameters on the prognosis of coronavirus disease-19 (COVID-19) in male patients with COVID-19 diagnosis.

Radical prostatectomy (RP) is the first-line treatment modality for prostate cancer and can be performed using retropubic or minimally invasive techniques. New technologies such as the da Vinci robotic system and three-dimensional (3D) laparoscopic imaging system have been developed to overcome the challenges of conventional laparoscopy. This study aimed to compare the perioperative, oncological, and functional outcomes of robot-assisted laparoscopic RP (RALP) and 3D laparoscopic RP (3D LRP).

Objectives: Ischemia/reperfusion (I/R) injury is a common cause of renal injury and to date, many pharmacological agents have been identified to decrease I/R injury. One of the potential compound that can target I/R injury is chlorogenic acid (CGA). It has potent antiinflammatory, antibacterial, anti-oxidant, analgesic and antipyretic activities in in vitro experiments and in vivo animal models.

Article Synopsis
  • This study evaluated how whortleberry can counteract kidney damage caused by cisplatin in rats.
  • It involved 48 female rats divided into six groups to analyze the impact of different doses of whortleberry alongside cisplatin treatment.
  • Results showed that whortleberry improved antioxidant levels and reduced kidney damage markers, suggesting it can help protect against cisplatin-induced toxicity.

Background: Overactive bladder (OAB), a symptom syndrome defined as urgency, is a common clinical condition, which sometimes cannot be satisfactorily treated with current medications in every subject; therefore, alternatives are needed.

Objectives: The aim of this in vitro study was to investigate the effects of ivabradine, a selective pacemaker If current inhibitor, on agonist-induced isometric contractions of the bladder smooth muscles.

Material And Methods: Urinary bladder strips were isolated from adult male Wistar rats and suspended in a tissue bath containing physiological solution.

Testicular torsion is one of the main causes of acute scrotum and may result in permanent damage of the testicular tissue. Color Doppler imaging has been frequently used in the diagnosis of testicular torsion and posttreatment follow-up period of the disease. There are some studies reporting the value and usefulness of diffusion-weighted imaging in the diagnosis of testicular torsion.

Introduction: Erectile dysfunction (ED) is frequently observed in end-stage renal disease (ESRD) patients on hemodialysis (HD) compared to non-uremic patients. This situation causes severe psychogenic problems in patients and disrupts the quality of life. Different phosphodiesterase type 5 (PDE-5) inhibitors have been used, and efficacies revealed, for the treatment of ED in HD patients; however, there are no studies related to udenafil use or results for HD patients.
