Can suction technology be a potential game changer that reshapes pediatric endourological interventions? Results from a scoping review.

Purpose: To systematically review the use of suction/vacuum-assisted retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) in children/adolescents with kidney stones.

Methods: The PICOS model (Patient Intervention Comparison Outcome Study type) was used to frame and answer the clinical question; P: children and adolescent men with kidney stones; I: use of suction during PCNL or RIRS; C: no suction devices or none; O: complications and stone-free rate (SFR); S: prospective and retrospective studies; case reports. The literature search was performed on 14th May 2024 using Embase, PubMed, and Scopus.

Risk factors of hematoma after SWL for renal calculi: analysis from RCTs and a literature review.

Objective: To identify risk factors of perinephric hematoma following extracorporeal shockwave lithotripsy (SWL) for renal calculi through combined analysis of two randomized controlled trials.

Patients And Methods: This post-hoc analysis included adult patients with solitary renal calculi ranging from 5 to 15 mm, treated with SWL between 2016 and 2022. All patients received cross-sectional imaging (either non-contrast computer tomography scan or magnetic resonance imaging) two days post-SWL to assess the presence and severity of perinephric hematoma.

Associations between glucocorticoid use and major adverse cardiovascular events in patients with prostate cancer receiving antiandrogen: a retrospective cohort study.

Background: Prednisolone/prednisone coadministration with abiraterone may explain abiraterone-related increase in cardiovascular risk. We explored this postulation and glucocorticoid's association with cardiovascular risk.

Methods: Patients with prostate cancer on androgen deprivation therapy and enzalutamide, or abiraterone with 5 mg (ABI + P5) or 10 mg (ABI + P10) daily total prednisolone/prednisone were followed up for major adverse cardiovascular events (MACE).

Pre-Op Hydronephrosis Predicts Outcomes in Patients Receiving Robot-Assisted Radical Cystectomy.

Introduction: Robot-assisted radical cystectomy (RARC) has gained momentum in the management of muscle invasive bladder cancer (MIBC). Predictors of RARC outcomes are not thoroughly studied. We aim to investigate the implications of preoperative hydronephrosis on oncological outcomes.

Impact of Pre-Operative Ureteroscopy on Bladder Recurrence Following Nephroureterectomy for UTUC.

(1) Introduction: Diagnostic ureteroscopy (URS) is an important component in the workup of upper tract urothelial carcinoma (UTUC). Whether URS was associated with increased recurrence in the bladder was not fully concluded. The current study aimed to evaluate the implication of URS on the incidences of intravesical recurrence following radical nephroureterectomy (RNU) in non-metastatic UTUC patients without prior history of bladder cancer via multi-institutional data.

Monopolar versus bipolar transurethral resection of bladder Tumour: post-hoc analysis of a prospective trial.

Introduction: Previously, in a randomised trial we demonstrated bipolar transurethral resection of bladder tumor (TURBT) could achieve a higher detrusor sampling rate than monopolar TURBT. We hereby report the long-term oncological outcomes following study intervention.

Methods: This is a post-hoc analysis of a randomized phase III trial comparing monopolar and bipolar TURBT.

Comparison of infection risk between enzalutamide and abiraterone in patients with prostate cancer.

Background: Enzalutamide and abiraterone may differ in their immunomodulatory effects, and the prednisone coadministered with abiraterone can be immunosuppressive. This study aimed to compare the risk of different types of infection in patients with prostate cancer receiving enzalutamide or abiraterone in combination with androgen deprivation therapy.

Methods: Patients with prostate cancer receiving enzalutamide or abiraterone in addition to androgen deprivation therapy in Hong Kong between December 1999 to March 2021 were identified in this retrospective cohort study and followed up until September 2021, death, or crossover.

Safety and Efficacy of Immediate Hyperthermic Intravesical Chemotherapy Following Transurethral Resection of Bladder Tumour (I-HIVEC).

The recurrence rate following endoscopic treatment of non-muscle-invasive bladder cancer (NMIBC) remains high. Standard treatment includes intravesical instillation of chemotoxic agents such as mitomycin C (MMC) to reduce recurrence. It is postulated that upfront administration of hyperthermic intravesical MMC (HIVEC) immediately after transurethral resection of bladder tumour (TURBT) may enhance its efficacy, but evidence from human trials is scant.

eLearning and transurethral prostate surgery: virtual tools for a real training.

Purpose Of Review: In the recent two decades, technological breakthrough has tremendously expanded the scope of transurethral prostate surgery. New gadgets and energy devices keep emerging to tackle benign prostatic obstruction, which was dealt with mainly by transurethral resection of prostate in the old days. Although this trend appears fascinating, it also means that urologists need quality training to attain surgical safety in performing these new surgeries.

Novel Strategies for Treating Castration-Resistant Prostate Cancer.

The development of castration resistance is an inevitable pathway for the vast majority of patients with advanced prostate cancer. Recently, there have been significant breakthroughs in the understanding and management options of castration-resistant prostate cancer. Three novel hormonal agents showed survival benefits in non-metastatic patients.

A Global Trend Analysis of Kidney Cancer Incidence and Mortality and Their Associations with Smoking, Alcohol Consumption, and Metabolic Syndrome.

Background: Kidney cancer is a major urological disease globally, with more than 400 000 new cases diagnosed every year.

Objective: To investigate incidence and mortality trends for kidney cancer and their associations with modifiable risk factors for kidney cancer.

Design, Setting, And Participants: The most up-to-date figures on kidney cancer incidence and mortality were collected from the GLOBOCAN database and the Cancer Incidence in Five Continents (CI5).

Role of pre-biopsy multiparametric MRI in prostate cancer diagnosis: Evidence from the literature.

As the conventional workup for diagnosing prostate cancer, transrectal systematic biopsy carries the risk of sepsis and overdiagnosis of insignificant prostate cancer. In recent years, multiparametric MRI (mpMRI) has revolutionized the diagnostic approach to prostate cancer. With widespread use of the prostate imaging and data system (PIRADS), MRI reporting has been more standardized.
