Mitochondrial stress increases the production of fumarate, an intermediate of the Krebs cycle. Fumarate non-enzymatically reacts with the thiol group of cysteine, leading to the production of -(2-succinyl)cysteine. Here, we quantified the concentration of fumarate, the free form of -(2-succinyl)cysteine, and advanced glycation end-products, including -(carboxymethyl)lysine and -(5-hydro-5-methyl-4-imidazolone-2-yl)-ornithine, in the serum of chronic kidney disease patients, using liquid chromatography-tandem mass spectrometry and an enzymatic assay. In a cross-sectional study, we evaluated the difference in metabolite concentration between healthy individuals ( = 22) and kidney transplant patients ( = 93). Additionally, we evaluated the metabolite concentration of end-stage renal disease patients ( = 17) before and 1, 3, 6, and 12 months after transplantation, in a longitudinal study. While the -(2-succinyl)cysteine and AGEs levels were significantly increased in accordance with the rising chronic kidney disease severity, they were significantly decreased after transplantation. However, fumarate levels were only significantly different in end-stage renal disease patients. The -(2-succinyl)cysteine levels correlated with the pre-existing kidney function marker. This study demonstrates that mitochondrial metabolic disorders contribute to impaired kidney function, and that measuring blood -(2-succinyl)cysteine levels may be a minimally invasive way to evaluate the metabolic change in chronic kidney disease.

Objective: To review and compare robot-assisted ipsilateral ureteroureterostomy (RALUU) and laparoscopic ipsilateral uretero-ureterostomy (LUU) in terms of efficacy and outcomes.
Methods: Clinical data of 65 children with complete renal ureteral duplication deformity admitted to the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022 were collected. Among these, 42 patients underwent laparoscopic ureteroureterostomy (LUU), designated as the LUU group, while 23 patients received robot-assisted laparoscopic ureteroureterostomy (RALUU), designated as the RALUU group.

Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture.

Introduction: Prostate cancer (PCa) is the commonest urologic cancer worldwide and the leading cause of male cancer deaths in Nigeria. In Nigeria, orchidectomy remains the primary androgen deprivation therapy. Dihydrotestosterone (DHT) is the active prostatic androgen, but its relationship with PCa severity has not been extensively studied in Africa.

Introduction: This study investigated the role of fibroblast growth factor 23 (FGF23)/Klotho in the mortality of patients hospitalized with coronavirus disease 2019 (COVID-19), excluding those with chronic kidney disease (CKD).
Methodology: A prospective cross-sectional study was conducted from April 2021 to May 2022. Patients who tested positive for COVID-19 via polymerase chain reaction and were hospitalized, were classified into two groups (survivors and non-survivors) at the end of their hospital follow-up.

Introduction: Hemoperfusion (HP), a blood filtration method targeting the removal of toxins and inflammatory elements, was investigated in this study. The objective was to present the observations in four individuals with confirmed COVID-19 who underwent several rounds of HP utilizing the HA330 cartridge at a hospital in Indonesia.
Case Studies: We report four cases of COVID-19 patients who underwent HP.
