Risk Factors for Conversion to Open Surgery in Laparoscopic Nephrectomy for Xanthogranulomatous Pyelonephritis: A Multicenter Study.

Xanthogranulomatous pyelonephritis (XGP) is an infrequent, but life-threatening, chronic granulomatous pyelonephritis. Surgical intervention can be challenging because of severe inflammation and often a fibrotic reaction that obliterates anatomical landmarks. In addition, a high rate of open conversion has been reported when performing a laparoscopic nephrectomy.

A novel mortality risk score for emphysematous pyelonephritis: A multicenter study of the Global Research in the Emphysematous Pyelonephritis group.

Background: Emphysematous pyelonephritis (EPN) is a necrotizing infection of the kidney and the surrounding tissues associated with considerable mortality. We aimed to formulate a score that classifies the risk of mortality in patients with EPN at hospital admission.

Materials And Methods: Patients diagnosed with EPN between 2013 and 2020 were retrospectively included.

Prognostic Factors of Morbimortality in Patients Treated for Xanthogranulomatous Pyelonephritis.

Nephrectomy is the treatment for xanthogranulomatous pyelonephritis (XGP), but the surgery is often technically complex and associated with a high incidence of postoperative complications. The objective of this study was to determine factors that can predict the probability of major postoperative complications, admission to intensive care, or mortality. We conducted a retrospective observational study of patients with XGP who underwent simple nephrectomy in a tertiary care hospital in Mexico from 2015 to 2022.

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.

Prognosis of Extended-Spectrum-Beta-Lactamase-Producing Agents in Emphysematous Pyelonephritis-Results from a Large, Multicenter Series.

Background: Emphysematous pyelonephritis (EPN) is a necrotizing infection of the kidney and surrounding tissues with significant mortality. We aimed to assess the clinical factors and their influence on prognosis in patients being managed for EPN with and without ESBL-producing bacteria and to identify if those with EPN due to ESBL infections fared any different.

Methods: A retrospective analysis was performed on patients with EPN diagnosis from 22 centers across 11 countries (between 2013 and 2020).

Comparison and outcomes of dusting versus stone fragmentation and extraction in retrograde intrarenal surgery: results of a systematic review and meta-analysis.

Introduction: Lithotripsy during retrograde intrarenal surgery (RIRS) can be achieved either by fragmentation and extraction or dusting with spontaneous passage. We aimed to perform a systematic review on the safety and stone-free rate after RIRS by comparing the techniques of dusting vs fragmentation/extraction.

Material And Methods: This review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement.

Laparoscopic vs Open Extravesical Ureteral Reimplantation in Pediatric Population: A Single-Center Experience.

Purpose: To evaluate the safety and efficacy of conventional laparoscopic vs open Lich-Gregoir ureteral reimplantation in pediatric vesicoureteral reflux.

Material And Methods: A retrospective study was conducted in a tertiary care hospital. Patients with vesicoureteral reflux who underwent open or laparoscopic Lich-Gregoir ureteral reimplantation from 2013-2020 were included.

Perioperative predictors for complications in patients with Xanthogranulomatous Pyelonephritis treated with nephrectomy.

Introduction: Xanthogranulomatous pyelonephritis is an inflammatory disease characterized by chronic obstruction and infection. This pathology is a life-threatening condition when surgical treatment is carried out. We decided to retrospectively evaluate whether there were perioperative factors that predict complications in patients who undergo nephrectomy.

What is the prognosis of emphysematous pyelonephritis associated with extended-spectrum beta-lactamases producing microorganisms?

Objective: To describe the microbiological characteristics in emphysematous pyelonephritis (EPN), demonstrate the frequency of extended-spectrum beta-lactamase (ESBL) microorganisms, and determine if these microorganisms are associated with the prognosis of patients with EPN.

Methods: We conducted a retrospective study in patients with a diagnosis of EPN in a tertiary care hospital of the northeast region of Mexico during the period from January 2011 to January 2016. Clinical variables were analyzed to determine association with the presence of ESBL-producing microorganisms.

Emphysematous Pyelonephritis and Emphysematous Cholecystitis: A Result of Uncontrolled Type 2 Diabetes.

Emphysematous pyelonephritis (EPN) is a life-threatening necrotizing infection that results in the presence of gas in the renal parenchyma, collecting system, and surrounding tissues. Up to 95% of patients with EPN have underlying uncontrolled diabetes mellitus. Emphysematous cholecystitis (EC) is a necrotizing infection defined by the presence of gas in the gallbladder.

Collision Tumor of the Kidney: Renal Cell Carcinoma Hidden in a Giant Angiomyolipoma in a Patient With Tuberous Sclerosis Complex.

A renal angiomyolipoma is a mixed mesenchymal benign tumor composed of smooth muscle, adipose tissue, and blood vessels. Malignant transformation of angiomyolipomas is anecdotal. To our knowledge, only 6 cases have been reported, and 4 of the patients had tuberous sclerosis complex diagnosed.

Emphysematous Pyelonephritis in a Horseshoe kidney.

Emphysematous pyelonephritis is a necrotizing renal infection that results in the presence of gas in renal parenchyma, collecting system, and surrounding tissues. Ninety-five percent of the patients have underlying uncontrolled diabetes mellitus, but non-diabetic patients may be affected due to ureteral obstruction and infection with gas forming pathogens. Several poor prognostic factors have been described, such as thrombocytopenia, acute kidney failure, impaired consciousness, and shock.
