Background: Although conventional pre-operative venography can accurately delineate venous anatomy as an alternative to ultrasound for hemodialysis access planning, it may carry a risk of contrast-induced acute kidney injury (AKI) and progression of renal failure in chronic kidney disease (CKD) patients not yet on dialysis. Therefore, the objective of this study was to evaluate the safety and efficacy of pre-operative venograms in pre-end-stage kidney disease (ESKD) patients.
Methods: We performed a retrospective cohort study (2018-2022) of consecutive pre-ESKD patients who underwent staged bilateral venograms for preoperative vein mapping prior to hemodialysis access creation at a tertiary care medical center.

Emphysematous pyelonephritis is a necrotizing infection of the renal parenchyma by gas-forming organisms, with a risk of the gas extending into peri-nephric or para-renal spaces and in advanced cases, the involvement may be extensive and bilateral. It is a common complication in patients with long-term diabetes, primarily caused by Gram-negative organisms or, in some cases, anaerobes. The diagnosis of emphysematous pyelonephritis is made by clinical features and confirmed by computed tomography.

Background: Aggressive angiomyxoma (AAM) is a rare benign mesenchymal tumor known for its aggressive behavior and high recurrence rates, with male cases of AAM being less frequently reported. This study presents a rare case of primary prostatic AAM characterized by a prostatic urethral mass obstructing the bladder outlet, resulting in acute renal dysfunction.

Urology Department, Instituto Mexicano del Seguro Social, Unidad de Medicina de Alta Especialidad N° 25, Monterrey, Nuevo León, Mexico.
Objective: We aimed to assess the impact of urinary diversion on survival in patients with advanced cervical cancer (CC) and hydronephrosis. Additionally, we examined the influence of other patient factors and urinary diversion type on survival.
Methods: A retrospective study analyzed survival in cervical cancer (CC) patients with hydronephrosis treated at two Mexican hospitals from 2011 to 2023.
