In this study, we aimed to evaluate the effect of HPL on different parameters by different centers and urologists. While doing this, we evaluated different parameters by comparing HPL(High Power laser) and LPL(Low-power laser). This is an observational, retrospective, comparative, multicentric study of prospectively organised database.

Objective: Although the clinical importance of prostate calculi has been understood over time, it is a urinary system disease that can cause different symptoms and can be ignored by urologists sometime. Clean intermittent catheter (CIC) is the gold standard method for bladder rehabilitation and urinary drainage in patients with neurogenic bladder. The aim of this study was to compare the incidence of prostate calculi and related pathologies between patients using CIC and not using CIC.

Introduction: The visceral adiposity index (VAI) is a gender-specific metabolic index that indirectly measures visceral adipose function and distribution using waist circumference, body mass index (BMI), and triglyceride and high-density lipoprotein (HDL) cholesterol values. To assess visceral fat in the diagnostic pathway of urinary stone patients, we investigated the relationship between the VAI and nephrolithiasis as well as the relationship between the VAI and stone and surgery-related parameters.

Material And Methods: Patients who underwent percutaneous nephrolithotomy and retrograde intrarenal surgery for kidney stones were included in the study.

The objective is to compare patients who underwent retrograde intrarenal surgery with and without a ureteral access sheath (UAS) using kidney injury molecule-1 (KIM-1) levels. We also examined the difference in kidney damage between standard and dual lumen UAS. Sixty patients diagnosed with kidney stones and scheduled for RIRS were randomized into three groups: RIRS without UAS (Group 1), 11Fr/13Fr Boston scientific Navigator™ UAS (Group 2), and 11Fr/13Fr dual lumen ClearPetra™ UAS (Group 3).

Objective: To make an extensive evaluation about the effects of histopathological findings acquired from the resection materials of patients who underwent transurethral resection of prostate (TUR-P) due to benign prostate hyperplasia (BPH) on postoperative urethral stricture formation.

Materials And Methods: Among patients who had TUR-P due to BPH and were followed up for minimum 6 months, 51 patients detected to have urethral stricture based on endoscopic imaging were included in the urethral stricture group (Group 1) and 52 patients without urethral stricture were included in the control group (Group 2). The relation between histopathological findings of TURP materials and postoperative stricture occurrence was investigated.

After nephron-sparing surgery (NSS), postsurgical fatty tumor could be mistakenly reported as angiomyolipoma during radiologic imaging of some patients. In the present paper, we studied the postsurgical fatty tumor detected after NSS but not covered before in the literature. In addition, we also evaluated whether the postsurgical fatty tumor was related to the surgical technique employed.

We have identified patients among non-obstructive azoospermia (NOA) cases in whom spermatozoa could not be detected despite treatment, but intermittent ejaculatory spermatozoon was found in their follow-up. NOA was observed in the retrospective screening at a rate of 15.35% among infertile men (n = 1976/12,871), while non-obstructive intermittent azoospermia (NO-IA) was detected at a rate of 6.

Introduction: Kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) are the leading novel biomarkers used efficiently in acute kidney injury (AKI). The levels of these biomarkers increase especially in the early period of nephrotoxic and ischemic renal damage. In this study, we aimed to investigate the clinical importance of NGAL and KIM-1 biomarkers used in the effective evaluation of kidney functions in patients with acute unilateral obstructive stone disease (AUOSD) in the management of endoscopic surgery.

Introduction: The primary aim of this study is to compare the efficacy and safety of retrograde intrarenal surgery (RIRS) among the children and adults with similar stone burdens and locations. Also, the secondary aim of this study is to identify the factors affecting the stone-free rates (SFRs) of RIRS.

Methods: We retrospectively compared perioperative results, SFRs, and complication rates (CRs) between pediatric (group 1, n: 55) and adult (group 2, n: 220) age groups diagnosed with kidney stones and treated by flexible ureterorenoscopy using the same instruments.

The aim of this study was to evaluate the efficacy and safety of transurethral cystolithotripsy (TUC) and percutaneous cystolithotripsy (PCC) in prepubertal patients with 10-20 mm bladder stones. The files of patients aged 12 years and under who were admitted to our clinic for bladder stones from January 2007 to January 2021 were reviewed retrospectively. Inclusion criteria were patients who were 12 years of age and under with 10-20 mm bladder stones, and who underwent endoscopic surgery (TUC or PCC).

Introduction: Testis torsion is a urological emergency and a serious situation that may cause testis atrophy, testicular dysfunction and infertility due to ischaemia/reperfusion(I/R) injury even with early intervention.

Objective: To assess the protective effect of dexpanthenol administered intratesticular after detorsion against testis I/R injury.

Study Design: Twenty-seven rats were randomly divided into 3 groups containing 9 rats each.

In this study, the efficiency of intracavernosal alprostadil + oral clomiphene citrate (CC) treatment in late-onset hypogonadism (LOH) accompanied by penile vasculogenic erectile dysfunction (PVED) in patients irresponsive to phosphodiesterase type 5 inhibitor treatment was evaluated. A total of 31 patients with concurrent PVED and LOH were included in the study. The patients were given intracavernosal alprostadil (10-20 μg) and oral CC (50 mg) every day for 12 weeks.

Background: We aimed to determine whether urine kidney injury molecule 1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) can be used as early noninvasive biomarkers of kidney injury in immunoglobulin A vasculitis.

Methods: Patients who were diagnosed with immunoglobulin A vasculitis were included in the study. Urine samples were collected for determination of urine KIM-1 and NGAL levels.

Purpose: To determine the efficacy of instillation frequency and submucosal injection of platelet-rich plasma (PRP) after urethral trauma to prevent urethral inflammation and spongiofibrosis.

Materials And Methods: Sixty-five rats were used in the study; 50 rats were randomized into 5 groups with 10 rats in each group and 15 rats were allocated for PRP preparation.
