A Retrospective Analysis of 83 Patients with Testicular Mass Who Underwent Testis-Sparing Surgery: The Eurasian Uro-oncology Association Multicenter Study.

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.

A New Safe and Ergonomic Manipulation Tool for the Flank-Free Supine Position: "U-Pad".

One of the most important problems in the supine percutaneous approach to the kidney is the narrow surgical surface area (SSA) in the lumbar region. Herein, the spatial and angular geometric advantages of the U-shaped lumbar pad (U-Pad) used as a new positioning tool for safety and ergonomics in the supine percutaneous approach have been revealed. Data of patients who underwent endoscopic combined intrarenal surgery (ECIRS) using the U-Pad for kidney stones between March and September 2021 were prospectively collected.

The creation of unilateral intermittent and unintermittent renal ischemia-reperfusion models in rats.

Background And Aim: This study aims to establish unilateral intermittent and unintermittent partial nephrectomy-like renal ischemia-reperfusion (I-R) model in rats and to compare the results with biochemical findings.

Material And Methods: The study was conducted on 24 adult 8-week-old male Wistar-Albino rats, each weighing s200-250 g. The rats were divided into three groups.

COVID-19 and urology: A bibliometric analysis of the literature.

Aim: The aims of this research were to analyse the urological literature published during the COVID-19 pandemic and to guide future research.

Material And Methods: Between 2019 and 2021, the Web of Science (WoS) All Databases collection was searched for publications related to COVID-19 and Urology. The keywords used during this search were coronavirus-19, COVID-19, SARS-CoV-2, novel coronavirus, 2019-nCoV, pandemic and/or urology.

External validation of the T.O.HO. score and derivation of the modified T.O.HO. score for predicting stone-free status after flexible ureteroscopy in ureteral and renal stones.

Objective: The T.O.HO.

A nationwide survey on the impact of COVID-19 pandemic on minimal invasive surgery in urology practice.

Objective: The beta-coronavirus (COVID-19) pandemic has changed the clinical approach of 93% of urologists worldwide, and this situation has affected the use of laparoscopic and robot-assisted laparoscopic methods, which are known as minimally invasive surgery (MIS). This study aimed to determine the effects of the COVID-19 pandemic on MIS in urology practice at national level.

Design, Setting And Participants: A total of 234 urologists in Turkey participated in an online survey between August 22 and September 23, 2020.

Comparison of before and after COVID-19 urology practices of a pandemic hospital.

Objective: The aim of this study is to compare the effects of COVID-19 on urology practice using pre- and post-pandemic data of a pandemic hospital.

Material And Methods: March 11 is considered as the beginning of COVID-19 and, changes in the number of the outpatient clinic examinations, non-surgical procedures, and surgery in the 8-week period before and during the pandemic were evaluated by weeks. Age, gender, and comorbid diseases of the operated patients were compared statistically.

Analysis of patients undergoing urological intervention amid the COVID-19: experience from the pandemic hospital.

Purpose: It is reported that surgical procedures performed during the COVID-19 pandemic are accompanied by high complications and risks. In this study, the urological interventions applied with appropriate infrastructure and protocols during the pandemic in the pandemic hospital that is carrying out the COVID-19 struggle are analyzed.

Methods: Urological interventions were reviewed in the 5-week period between March 11 and April 16.

Retrograde intrarenal surgery of renal stones: a critical multi-aspect evaluation of the outcomes by the Turkish Academy of Urology Prospective Study Group (ACUP Study).

Aims: To outline and evaluate the incidence, management and follow-up of the residual fragments (RFs) following retrograde intrarenal surgery (RIRS) of renal stones by the Turkish Academy of Urology Prospective Study Group (ACUP Study).

Methods: Following the ethical committee approval, 15 centers providing data regarding the incidence, management, and follow-up of RFs after RIRS were included and all relevant information was recorded into the same electronic database program ( https://acup.uroturk.

Recurrent bladder cystitis: who takes the role?

Purpose: In this review, we discuss how the approach should be throughout the symptomatic and diagnostic process of recurrent bladder cystitis.

Methods And Results: The available literature regarding recurrent bladder cystitis in the PubMed database has been reviewed. While urinary tract infections (UTIs) are amongst the most commonly seen diseases in society, the probability of having a UTI in women within a year is 15%.

Development of a prospective data registry system for retrograde intrarenal surgery in renal stones: Turkish Academy of Urology Prospective Study Group (ACUP study).

Objective: We aimed to report the development of a prospective data registry by generating a retrograde intrarenal surgery (RIRS)-specific electronic case report form (eCRF), which can be used by multiple centers in Turkey.

Material And Methods: The Stone Disease Study Group of Turkish Urology Academy developed a template for the necessary data to be collected, which was then implemented within a dedicated server. Urologists from different universities, research and training centers, and private hospitals were invited to participate in this data registry.

Intraoperative Evaluation of Ureteral Access Sheath-Related Injuries Using Post-Ureteroscopic Lesion Scale.

Objective: In the present study, intraoperative ureteral injuries inflicted during retrograde intrarenal surgery (RIRS) with ureteral access sheath (UAS) use were evaluated using the Post- Ureteroscopic Lesion Scale (PULS).

Materials And Methods: Patients in whom a UAS was used during RIRS and for whom ureter images were video recorded during the procedure were included in the study. PULS grading was performed after UAS removal, and video sequences of all patients were viewed by a junior resident, a senior resident, and four experienced urologists and assessed according to the PULS.

Is retrograde flexible nephrolithotripsy feasible for calyceal diverticular stone?

The aim of this study is to manage the calyceal diverticular (CD) stone, several treatment options were applied but it is still a challenging condition of endourology. In this retrospective study, we aim to report the results of our patients with CD stones treated with retrograde flexible nephrolithotripsy (RFNL). A total of 47 patients (55 procedures) who underwent RFNL by a single surgeon for CD stones from January 2004 to March 2013 were evaluated retrospectively.
