Clinical Presentation, Microbiological Characteristics, and Their Implications for Perioperative Outcomes in Xanthogranulomatous Pyelonephritis: Perspectives from a Real-World Multicenter Practice.

Xanthogranulomatous pyelonephritis (XGP) is an uncommon chronic granulomatous infection of renal parenchyma. XGP is often associated with long-term urinary tract obstruction due to stones and infection. We aimed to analyze the clinical, laboratory, and microbial culture profiles from bladder and kidney urine of patients who were diagnosed with XGP.

Perioperative outcomes and risk factors for major complications associated with nephrectomy for Xanthogranulomatous pyelonephritis: a multicenter study.

Purpose: To determine the risk factors associated with major complications in patients with histologically confirmed Xanthogranulomatous pyelonephritis (XGP) who underwent nephrectomy.

Methods: A multicenter retrospective study was performed including patients who underwent nephrectomy between 2018 and 2022 with histopathological diagnosis of XGP. Clinical and laboratory parameters at the initial presentation were evaluated.

Laparoscopic nephrectomy in patients with renal exclusion secondary to urolithiasis. Which factors can predispose conversion to open surgery?

Background: The prevalence of urolithiasis is 7-10% and has increased over the past years. Simple nephrectomy is, therefore, indicated when renal exclusion is associated with recurrent urinary tract infections and/or chronic pain.

Objective: The aim of the study was to describe the surgical experience of laparoscopic nephrectomy (LPN) due to urolithiasis in Mexican South-east and which factors can predispose conversion to open surgery.
