Systemic Inflammatory Index: A Novel Biomarker for Predicting the Progression in Active Surveillance in Patients with Prostate Cancer.

Objective: To investigate active surveillance (AS) for patients with prostate cancer to show the systemic inflammatory index (SII) progression and to evaluate whether SII will be an AS criterion in PCa patients.

Study Design: Descriptive study. Place and Duration of the Study: Department of Urology, University of Health Sciences, Prof.

Significance of PPD Test for the Relationship Between BCG Vaccine and COVID-19 in Patients on Kidney Transplant Waiting List.

Background: The aim of this study was to determine the relationship between purified protein derivative of tuberculin (PPD) values, an indicator of BCG protection, and COVID-19 disease in patients with end-stage renal disease (ESRD) on the kidney transplant waiting list.

Methods: Age, sex, dialysis type, ERSD etiologies, and PPD values of patients on the renal transplant waiting list were recorded. SARS-CoV-2 PCR data, whether the patients were previously infected with the virus, and, if infected, the severity of the disease were noted.

A new percutaneous nephrolithotomy position in horseshoe kidney: 45 degrees sided prone.

Introduction: In this study we aimed to determine the effects of the 45 degrees sided prone position to the surgeon's comfort, operation time, fluoroscopy time and complications at the operation of percutaneous nephrolithotomy (PCNL) for the treatment of kidney stone of horseshoe kidney (HK) or rotation anomaly kidney.

Material And Methods: Thirty eight patients (25 male, 13 female) with renal calculi and HK, underwent PCNL. After the amplatz sheath was inserted into the collecting system, the patients in group 1 (n:20) were taken to the 45 degrees side position to the side of the operation and patients in group 2 (n:18) were operated in classical prone position.

Comparison of Urethral Dilation with Amplatz Dilators and Internal Urethrotomy Techniques for the Treatment of Urethral Strictures.

Purpose: The most common option for the management of urethral stricture (US) is direct visual internal urethrotomy (DVIU), because it is an easy and minimally invasive technique but the low success and high recurrence rates of this technique make urologists research for different types of therapeutic alternatives in stricture treatment. In this study we aimed to compare the internal urethrotomy with amplatz dilation for the treatment of male US.

Materials And Methods: A total of sixty patients, who have been operated due to urethral stricture were enrolled into this study.

Interobserver variability in Gleason histological grading of prostate cancer.

Objective: The aims of this study were to evaluate the reproducibility of the Gleason grading system and to compare its interobserver variability with the novel Gleason grade grouping proposal using a large sample volume.

Materials And Methods: In total, 407 pathology slides of prostate needle biopsies from 34 consecutive patients with prostate cancer were re-evaluated. The International Society of Urological Pathology 2005 modified Gleason grading system with Epstein's modification was used.

Comparison between Retroperitoneal and Transperitoneal Approaches in the Laparoscopic Treatment of Bosniak Type I Renal Cysts: A Retrospective Study.

Purpose: We retrospectively compared laparoscopic transperitoneal and retroperitoneal approaches for the decor­tication of simple renal cysts with respect to safety, postoperative pain, and clinical results.

Materials And Methods: The study included 40 patients (28 males and 12 females) with symptomatic simple renal cysts and who underwent laparoscopic cyst decortication, and they were evaluated retrospectively. Patients' age, gender, disease-specific history, comorbid disease and family history, in general and urological and phys­ical examination findings were recorded.

Internal urethrotomy versus plasmakinetic energy for surgical treatment of urethral stricture.

Purpose: we aimed to compare the longterm outcome of surgical treatment of urethral stricture with the internal urethrotomy and plasmakinetic energy.

Material And Methods: 60 patients, who have been operated due to urethral stricture were enrolled in our clinic. None of the patients had a medical history of urethral stricture.

Single vs. double dartos interposition flaps in preventing urethrocutaneous fistula after tubularized incised plate urethroplasty in primary distal hypospadias: a prospective randomized study.

Introduction: This prospective study was designed to compare symmetrical overlapping double flaps with a single dartos flap in regard to fistula formation as an adjunct to tubularized incised plate urethroplasty (TIPU).

Patients And Methods: 77 consecutive children with primary coronal or subcoronal hypospadias were randomized into 2 groups. A single layer dartos flap was used to cover the anastomotic site in the first group (37 patients).

High power diode laser vaporization of the prostate: preliminary results for benign prostatic hyperplasia.

Purpose: Vaporization techniques using lasers have gained wide acceptance for benign prostatic hyperplasia as an alternative to transurethral prostate resection. The high power, 980 nm wavelength diode laser is a new promising alternative with a more rapid ablation rate and excellent hemostatic properties, as shown in ex vivo and in vivo animal models. We prospectively evaluated vaporization efficiency of the high power, 980 nm diode laser for bladder outlet obstruction due to benign prostatic hyperplasia.
