PURPOSE: Growing evidence have suggested an association between nephrolithiasis and cardiovascular disease (CVD) with unclear mechanism. Oxidized low-density lipoproteins (oxLDL) induces atherosclerosis and was found to be the possible link between these two diseases. Our study aimed to examine the serum, urine and kidney expression of oxLDL in relation to large calcium oxalate (CaOx) renal stone disease. METHODS: A total of 67 large CaOx dominant renal stone patients and 31 stone-free controls were enrolled in the prospective case-control study...

PURPOSE: To analyse the pathological features and survival of patients with a PI-RADS 5 lesion on pre-biopsy MRI. METHODS: We extracted from a European multicentre prospectively gathered database the data of patients with a PI-RADS 5 lesion on pre-biopsy MRI, diagnosed using both systematic and targeted biopsies and subsequently treated by radical prostatectomy. The Kaplan-Meier model was used to assess the biochemical-free survival of the whole cohort and univariable and multivariable Cox models were set up to study factors associated with survival...

PURPOSE: Abnormalities in autonomic function are associated with an overactive bladder (OAB). Heart rate variability is generally used as the sole assessment of autonomic activity; however, we utilized neuECG, a novel method of recording skin electrical signals, to assess autonomic nervous function in healthy controls and patients with OAB before and after treatment. METHODS: The prospective sample included 52 participants: 23 patients newly diagnosed with OAB and 29 controls...

PURPOSE: Radical cystectomy (RC) is the standard treatment for high-risk non muscle-invasive bladder cancer (NMIBC) failing first BCG treatment. A second BCG course is an option for those patients who refuse RC or are not eligible for it, but its success rate is quite low. Aim of the present study was to determine whether the addition of intravesical electromotive drug administration of mytomicin-C (EMDA-MMC) improved the efficacy of second BCG course. METHODS: Patients with high-risk NMIBC having failed first BCG treatment and having refused RC were offered a second BCG induction course either alone (group A) or combined with EMDA-MMC (group B)...

BACKGROUND: The need of ureteric access sheath (UAS) in retrograde intrarenal surgery (RIRS) has been controversial for gaining high success in terms of stone free rate (SFR), reducing operative times and complications. There has been lack of high level of evidence in the literature on this topic. MATERIALS AND METHODS: This prospective randomized controlled trial (RCT) was conducted in the Department of Urology, PGIMER, Chandigarh from July 2019 to Dec 2021. The effect of UAS on the outcome of RIRS (SFR, operative time and complications) for renal stone disease was assessed...

PURPOSE: Lynch syndrome (LS) is an autosomal dominant genetic syndrome resulting in a wide spectrum of malignancies caused by germline mutations in mismatch repair genes (MMR). Gene mutations have different effects and penetrance between the two genders. The aim of this review is to offer a gender-specific evidence-based clinical guide on diagnosis, screening, surveillance, and counselling of UTUC patients with LS. METHODS: Using MEDLINE, a non-systematic review was performed including articles between 2004 and 2022...

PURPOSE: Previous research on genital gender-affirming surgery lacked to build a framework that took various surrounding factors into account. E.g., transgender health care services are delivered in both centralized (by one interdisciplinary institution) and decentralized settings (by different medical institutions spread over several locations). The present study investigated the effects of different structural and clinical aspects of gender-affirming genital surgery on psychosocial outcomes...

PURPOSE: Depression and anxiety have been associated with lower urinary tract symptoms (LUTS) in several studies. In our population, the prevalence of LUTS is high, consequently, it is essential and an objective of this study, to determine the association between anxiety, depression, and LUTS in a large Hispanic population. METHODS: A sub-analysis of a cross-sectional population-based study to estimate LUTS prevalence in the Colombian population was performed (COBaLT study) (Plata et al...

BACKGROUND: The impact of early drainage on mortality in patients with obstructive pyelonephritis with urolithiasis was evaluated. METHODS: We identified 34,924 patients in the Japanese Diagnosis Procedure Combination database with obstructive pyelonephritis with urolithiasis receiving ureteral drainage. The effects of early drainage (1-2 days) compared to those of delayed drainage (on 3-4 and ≥ 5 hospital days) on mortality were evaluated among 31,696 patients hospitalized for ≥ 5 days...

INTRODUCTION: Anderson-Hynes pyeloplasty is the technique of choice for the treatment of pyeloureteral junction obstruction (PUJO) with an excellent success rate. Minimally invasive surgery has become the standard of care for the management of PUJO in children. Although it has been comparable to the open approach at all levels, its diffusion or employment in younger children has not been widely adopted. Our aim is to evaluate laparoscopic pyeloplasty outcomes from international academic centers in children under 1 year of age, focusing on feasibility and outcomes including possible complications...

PURPOSE: Female representation at scientific conferences is crucial for encouraging women pursuing an academic career. Nevertheless, gender inequity at urological conferences is common place and women are often stereotyped choosing functional urology. However, there is no evidence whether female representation is higher in functional urology. This investigations aims to analyze gender representation at functional urology sessions. METHODS: National and international urological congresses between 2019 and 2021 with a focus on functional urology and female urology sessions were evaluated...

PURPOSE: There is substantial variability in multiparametric MRI (mpMRI) protocols and inter-readers' agreement. We tested the effect of a central mpMRI review on the detection of clinically significant PCa (csPCa) in a tertiary referral center. METHODS: We retrospectively analyzed a cohort of 364 consecutive men with a positive externally performed mpMRI (PI-RADS ≥ 3) who underwent a targeted biopsy (TBx) plus a systematic biopsy at a single tertiary referral center (2018-2020)...

PURPOSE: To identify prognostic factors of failure in patients undergoing perineal urethrostomy (PU) with Blandy technique, with inverted U-shaped perineal flap. METHODS: This is a retrospective study of PU of non-oncological causes (2001-2017). Data of age, BMI, history of diabetes mellitus, etiology of urethral stricture, type of stricture, previous surgeries, dilatation and suprapubic catheter were collected. Failure was defined as the need for any instrumentation after surgery...

PURPOSE: Treatment of primary prostate cancer extremely depends on preoperative stage. The role of 18 F-1007-PSMA-PET/CT in preoperative staging has not been well defined. Our aim was to compare the diagnostic performance of 18 F-1007-PEMA-PET/CT, mpMRI, and mpMRI + PEMA-PET/CT in local progression and lymph node invasion of prostate cancer using histopathology as the gold standard. MATERIALS AND METHODS: In this retrospective study, all patients with prostate cancer who underwent mpMRI and 18 F-PSMA-1007-PET/CT before operation were included...

OBJECTIVE: To evaluate a single surgeon's 20-year experience with robotic radical prostatectomy. METHODS: Patients who had undergone robot-assisted laparoscopic prostatectomy by a single surgeon were identified via an IRB approved prospectively maintained prostate cancer database. Patients were divided into 5-year cohorts (cohort A 2001-2005; cohort B 2006-2010; cohort C 2011-2015; cohort D 2016-2021) for analysis. Oncologic and quality of life outcomes were recorded at the time of follow-up visits...

PURPOSE: To evaluate the perioperative outcomes of retrograde intra-renal surgery (RIRS) for lower pole stones (LPS) and factors affecting stone-free rate (SFR). METHODS: Data from 20 centers were retrospectively reviewed. Inclusion criteria were adult patients, normal renal anatomy, and LPS. Exclusion criteria were bilateral surgery, concomitant surgery for ureteral stones. SFR was defined as a single residual fragment (RF) ≤ 2 mm and evaluated 3-months after surgery...

PURPOSE: To describe the national-level patterns of care for local ablative therapy among men with PCa and identify patient- and hospital-level factors associated with the receipt of these techniques. METHODS: We retrospectively interrogated the National Cancer Database (NCDB) for men with clinically localized PCa between 2010 and 2017. The main outcome was receipt of local tumor ablation with either cryo- or laser-ablation, and "other method of local tumor destruction including high-intensity focused ultrasound (HIFU)"...

PURPOSE: In selected ADPKD patients, a nephrectomy is required in the work-up for a kidney transplantation. Because the impact of this procedure is unknown, we investigated the effect of pre-transplantation nephrectomy on quality of life in this group. METHODS: In this retrospective cohort study all ADPKD patients, ≥ 18 years, who received a kidney transplantation in 2 ADPKD expertise centers between January 2000 and January 2016, were asked to participate...
