Article Synopsis
  • Ureteroscopy (URS) is a common surgical method for treating urinary stones smaller than 2 cm, and the use of preoperative stenting (PS) is debated regarding its benefits and outcomes compared to not using it (NPS).
  • A comprehensive analysis of 23,668 patients from various studies found that PS led to higher stone-free rates (SFR) and lower rates of complications during and after surgery, particularly when flexible URS was used.
  • Overall, PS appears to improve surgical outcomes without increasing complications, suggesting a need for further research on its cost-effectiveness and impact on patient quality of life.

Article Synopsis
  • This study examines pelvic organ-preserving radical cystectomy in women with muscle-invasive bladder cancer, aiming to understand its oncological outcomes compared to standard radical cystectomy.
  • A systematic review analyzed six studies totaling 597 patients, finding no significant differences in overall survival, cancer-specific survival, or recurrence-free survival between the two surgical approaches.
  • While most studies had a moderate risk of bias, the findings suggest that pelvic organ preservation does not adversely affect cancer outcomes, but further research is needed for clearer insights.

Objective: To conduct a systematic review and meta-analysis to evaluate the effectiveness and safety of PCNL performed as a day-case surgery in comparison to inpatient PCNL.

Methods: Databases were searched up to January 27, 2024, for randomized and non-randomized studies comparing outcomes between day-case PCNL and inpatient PCNL. Pooled data were analyzed using a random-effects (RE) model when Higgins I2% heterogeneity values were >50%; otherwise, a fixed-effects model was employed.

Background There is a clear association between testicular cancer and microlithiasis when there are predisposing risk factors such as the history of germ cell tumors in first-degree relatives, testicular atrophy, Klinefelter's syndrome, and cryptorchidism. This study aimed to establish an association between microlithiasis and the histological subtype of testicular cancer by analyzing data on Hispanic population. Methods A retrospective cohort, longitudinal, comparative, and analytic study was conducted on patients with a confirmed diagnosis of primary testicular cancer.

Urothelial bladder cancer (UBC) is an exceptionally rare condition in adolescents between 15 and 19 years of age. Typically, adolescents and pediatric patients with UBC are more likely to have a favorable histological report. The aim of the paper is to report our experience in the management of a 16-year-old patient with UBC with no risk factors that came to the office because of a history of painless gross hematuria.

Wünderlich syndrome (WS) is a spontaneous retroperitoneal hemorrhage confined to the subcapsular or perinephric space without a history of trauma. Since it is a rare condition with a significant mortality rate if not treated timely, it is essential to identify its risk factors and early clinical manifestations for a favorable outcome. Various conditions are associated, but the most common causes are benign and malignant renal neoplasms.

Introduction: High-grade adenocarcinoma of the prostate tends to have denser glandular structures and a prominent desmoplastic reaction, which could be detected by magnetic resonance imaging (MRI) with a super-high b-value in diffusion-weighted imaging (DWI) sequence, to differentiate it from low-grade carcinomas.

Objective: To evaluate the diagnostic validity of the diffusion sequence with values ​​of b4000 s/mm2 for the diagnosis of high-grade prostate cancer (Gleason score ≥ 7).

Materials And Methods: It is a retrospective analytical study of male patients who have undergone a prostate biopsy and count with a prostate MRI with a DWI sequence of a super-high b-value (4000 s/mm2).
