PGIMER, Chandigarh, India.

Xanthogranulomatous pyelonephritis is a rare, painful inflammatory subtype of chronic renal infection, which can lead to severe parenchymal destruction. It imitates virtually every other renal inflammatory disease. We report a 51-year-old male presenting with left flank pain, on evaluation found to have a renal mass with a history of nephron-sparing surgery in the same kidney performed 6 months previously.

Imaging Characterization of Renal Masses.

Medicina (Kaunas) 2021 Jan 8;57(1). Epub 2021 Jan 8.

Radiology Department, Hospital Clinic, University of Barcelona (UB), 08036 Barcelona, Spain.

The detection of a renal mass is a relatively frequent occurrence in the daily practice of any Radiology Department. The diagnostic approaches depend on whether the lesion is cystic or solid. Cystic lesions can be managed using the Bosniak classification, while management of solid lesions depends on whether the lesion is well-defined or infiltrative. Read More

Medicina (Kaunas) 2021 Jan 1;57(1). Epub 2021 Jan 1.

Radiology department, Urology and Nephrology Center, Mansoura University, 35516 Mansoura, Egypt.

There are many acute and chronic infections affecting the urinary tract including bacterial, fungal and viral infections. Urinary tract infections (UTIs) can present in many different patterns with variable degrees of severity varying from asymptomatic and uncomplicated forms to life threatening complicated infections. Cross-sectional imaging techniques-including both computed tomography (CT) and magnetic resonance imaging (MRI)-have become very important tools not only for evaluation of UTIs, but also for detection of associated complications.

Complicated pyelonephritis associated with chronic renal stone disease.

Radiol Med 2021 Apr 27;126(4):505-516. Epub 2020 Nov 27.

Department of Radiology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Via Albertoni 15, Bologna, Italy.

Purpose: This article reviews imaging manifestations of complicated pyelonephritis associated with chronic renal stones disease, in particular xanthogranulomatous pyelonephritis (XGP) and emphysematous pyelonephritis (EPN), as potential mimics of other renal diseases and malignances and provides helpful tips and differentiating features that may alert the radiologist to suspect a diagnosis of infection.

Materials And Methods: A retrospective review of the records from 6 adult patients (5 females and 1 male, mean age 72,3 years) with diagnosis of XGP associated with chronic nephrolithiasis and 7 adult patients (6 females and 1 male, mean age 59,3 years) with diagnosis of EPN associated with chronic nephrolithiasis from January 2010 to January 2020 was carried out. Computed tomography urography (CTU) with at least an unenhanced scan, and the parenchymal and excretory phases after contrast medium administration performed at our Teaching Hospital were included.

Angiomyolipoma of the kidney: from simple hamartoma to complex tumour.

Pathology 2021 Jan 31;53(1):129-140. Epub 2020 Oct 31.

Department of Diagnostic and Public Health, Section of Pathology, University of Verona, Verona, Italy; Department of Pathology, Pederzoli Hospital, Peschiera, Italy. Electronic address:

Angiomyolipoma is the most common mesenchymal tumour of the kidney, even if for a long time it has been viewed as a hamartoma rather than a neoplasm. It belongs to a family of neoplasms, named PEComa, characterised by the constant presence of perivascular epithelioid cells that co-express smooth muscle and melanogenesis markers. Angiomyolipoma can occur in patients with tuberous sclerosis, a hereditary syndrome due to the alteration of TSC1 or TSC2 genes, or sporadically. Read More

Long-Term Antibiotic Treatment Prior to Laparoscopic Nephrectomy for Xanthogranulomatous Pyelonephritis Improves Postoperative Outcomes: Results from a Multicenter Study.

J Urol 2021 Mar 20;205(3):820-825. Epub 2020 Oct 20.

Department of Urology, University of California, Irvine, California.

Minimally invasive nephrectomy for inflammatory renal disease.

Asian J Urol 2020 Oct 14;7(4):345-350. Epub 2019 Sep 14.

Division of Urology, Hospital Universitario San Ignacio, Pontificia Universidad Javeriana, School of Medicine, Bogotá D.C., Colombia.

Objective: Once chronic inflammatory renal disease (IRD) develops, it creates a severe peri-fibrotic process, which makes it a relative contraindication for minimally invasive surgery (MIS). Our objective is to show that laparoscopic nephrectomy (LN) is a surgical option in IRD with fewer complications and better outcomes.

Methods: Retrospective review of patients who underwent a modified-surgical laparoscopic transperitoneal nephrectomy was performed. Read More
