Article Synopsis
- The study aimed to assess how three-dimensional (3D) modeling of MRI images affects positive surgical margins (PSM) in patients undergoing radical retropubic prostatectomy (RRP).
- A total of 81 patients were split into two groups: one group used 3D modeling to guide surgery, while the other relied on traditional evaluations of MRI scans.
- Results showed that the 3D group had a significantly lower PSM rate (14.6%) compared to the non-3D group (45%), highlighting the benefits of 3D modeling and collaboration between radiologists and surgeons for better surgical outcomes.
Aim: To evaluate the effect of 5 alpha-reductase inhibitor (5-ARI) treatment on prostate cancer detection by multiparametric magnetic resonance imaging (mpMRI).
Methods: We retrospectively collected data on 429 patients who underwent mpMRI before prostate biopsy in the Urology Department of Giresun University Training and Research Hospital between March 2018 and December 2021. The patients were categorized as those who had never been treated with 5-ARI (n=359) and those who were treated with 5-ARI for more than six months (n=70).
Background: Microplastics are ubiquitous, widespread environmental pollutants with unavoidable human exposure. Herein, it was aimed to investigate the presence of microplastics in prostate tissue.
Methods: Prostate tissues from 12 patients who underwent Trans Urethral Resection of the Prostate (TUR-P) were analyzed to investigate the presence of microplastics.
Article Synopsis
- The study aimed to evaluate how effective multiparametric magnetic resonance imaging (mp-MRI) is in diagnosing granulomatous prostatitis in patients receiving BCG treatment for bladder cancer.
- Ten male patients were observed before and after BCG treatment, assessing factors like prostate-specific antigen (PSA) levels, digital rectal examination (DRE) results, and mp-MRI findings.
- Results showed a significant increase in PSA levels and abnormal DRE findings after BCG treatment, suggesting that elevated PSA and abnormal MRI results may indicate granulomatous prostatitis, potentially reducing the need for unnecessary biopsies.
Objective: The aim of this study was to demonstrate the effect of extracorporeal shock wave lithotripsy application on the success and complications of ureteroscopic lithotripsy in proximal ureter stones.
Methods: The data of 87 patients who did not respond to shock wave lithotripsy and underwent ureteroscopic lithotripsy were retrospectively analyzed and classified as group I, and 99 patients who received ureteroscopic lithotripsy as primary treatment were classified as group II. Demographic features, response to treatment, and preoperative and postoperative complications were compared between the two groups.
PURPOSE We aimed to investigate the accuracy of Vesical Imaging - Reporting and Data System (VI-RADS) in the detection of muscle-invasive bladder cancer (MIBC) and to determine which factors affect the results of this scoring system. METHODS A prospective data analysis of 80 patients who were detected to have bladder tumor was performed between March 2019 and October 2020. VI-RADS scoring was used to determine the probability of muscle invasion.

Background: Creatinine elevation and changes in urinalyse parameters may be seen due to acute kidney injury during COVID-19. In the present study, we aimed to investigate the changes in urinalysis of COVID-19 patients with normal kidney function.
Methods: The data of COVID-19 patients with normal renal functions were retrospectively analyzed.
Purpose: We aimed at comparing the success and complications of early semirigid ureteroscopy (URS) and elective URS in ureteral calculi with renal colic that do not respond to analgesics.
Methods: We retrospectively analyzed the data of 690 patients with obstructive ureteral stones who underwent URS with stone retrieval. 247 patients who underwent early URS within the first 12 h were classified as group I and 443 patients who underwent elective URS as group II.
Urethral stricture is a common urological pathology with a high recurrence rate after treatment. Urethral manipulations are among its main causes. In this paper, urethral stricture developed secondary to urethral catheterization and was treated with cold-knife internal urethrotomy and the Otis urethrotomy procedure.

The ischemia completely resolved following treatment with iv pentoxifylline (PTX) for six days, and the patient was discharged without any problems.

We investigated the effects of dipyridamole and acetylsalicylic acid (ASA), 2 well-known platelet inhibitors, on testicular ischemia reperfusion injury.
Methods: Thirty adult male Sprague-Dawley rats were randomly divided into 5 groups (n = 6 for each group): control, sham-operated, torsion/detorsion (T/D), T/D + dipyridamole, and T/D + ASA.
