Pyonephrosis complicated with spontaneous intraperitoneal rupture and diffuse peritonitis: Case report and literature review.

Pyonephrosis is a serious condition that can lead to kidney dysfunction, loss of the organ, and even fatal end due to its complications. The underlying etiologic factors include lithiasis, recurrent urinary infections, ureter stricture, ureteropelvic junction obstruction, malignancy, and retroperitoneal fibrosis. One of the rare possible complications of pyonephrosis is a retroperitoneal rupture with spontaneous communication to the abdomen causing secondary peritonitis.

A rare case: IgG4-related chronic inflammatory disease with kidney involvement.

IgG4-related disease is an inflammatory, multisystemic disease that affects the immune system. The disease progresses to fibrosis due to inflammation. Retroperitoneal fibrosis is a serious complication.

This study reports the first case of IgG4-related retroperitoneal fibrosis after the administration of chemotherapy with nivolumab and ipilimumab (NI therapy). An 80-year-old man developed lower abdominal pain eight months after NI therapy was initiated.

Adjunctive Surgery Is Often Without Oncological Benefit at Time of Postchemotherapy Retroperitoneal Lymph Node Dissection.

Purpose: Postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) for advanced nonseminomatous germ cell tumors (GCTs) aims to resect all remaining metastatic tissue. Resection of adjacent visceral or vascular organs is commonly performed for complete resection. Resection of organs harboring only necrosis results in relevant overtreatment.

Immunohistochemical expression of DnaJ homolog subfamily B member 9 in immunoglobulin G4-related disease: a pilot study.

Objectives: DnaJ homolog subfamily B member 9 (DNAJB9) is a co-chaperone protein that governs the functions and integrity of cells. In immunoglobulin G4-related disease (IgG4-RD), DNAJB9 was shown to be upregulated in plasma cells, but its immunohistochemical expression has never been explored. This pilot study aims to investigate the immunohistochemical distribution and intensity of DNAJB9 in IgG4-RD tissue specimens.

IgG4-related periaortitis presenting as left flank pain.

We present the case of periaortitis which presented initially with left flank pain. A diagnosis of IgG4-related disease (IgG4-RD) was subsequently made and managed as such. IgG4-RD is rare, can be difficult to diagnose, and requires clinical, serological, radiological and pathological correlation, particularly given that serum IgG4 levels may be normal.

Unilateral post-chemotherapy robot-assisted retroperitoneal lymph node dissection in Stage II non-seminomatous germ cell tumor: A tertiary care experience.

Objective: Post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) represents an integral component of the management of patients with non-seminomatous germ cell tumor (NSGCT). Modified templates have been proposed to minimize the surgical morbidity of the procedure. Moreover, the implementation of robotic surgery in this setting has been explored.

Left Ureterocalycostomy With Ileal Interposition for Retroperitoneal Fibrosis in Patient With Erdheim-Chester Disease.

Background: Erdheim-Chester disease (ECD) is a rare progressive non-Langerhans' cell histiocytic multisystem disorder with a broad spectrum of clinical manifestations, including infiltrative perinephric with ureteral involvement resulting in hydronephrosis, renal atrophy, and eventual renal failure.

Objective: To present a patient with ECD with bilateral renal/ureteral involvement managed with bilateral percutaneous nephrostomy tubes (PCNT) and trametinib who underwent bilateral robotic upper tract reconstruction, the first such published report. The video demonstrates only the left-sided repair, which posed specific challenges and demonstrates reconstructive techniques useful in complex upper tract repairs with limited tissue availability.

Robotic approach to remove four tailgut cyst cases in Brazil: a case series.

Tailgut cysts are rare congenital lesions that are remnants of the embryonic hindgut. This abnormality presents with non-specific symptoms or no symptoms; therefore, misdiagnosis is common. Here, we present four cases of tailgut cysts that were successfully removed using a robotic surgical approach.

Rare case of inflammatory abdominal aortic aneurysm with an aortocaval fistula.

Inflammatory abdominal aortic aneurysms (IAAA) are a distinct subcategory of abdominal aortic aneurysms that make up roughly 5%-10% of all abdominal aortic aneurysm (AAA) cases. Inflammatory AAA (IAAA) is distinguished from traditional atherosclerotic AAA by the triad of thickened aneurysm wall, extensive perianeurysmal/retroperitoneal fibrosis, and dense adhesions of adjacent abdominal organs. The purpose of this report is to examine the clinical course of a rare case of inflammatory abdominal aortic aneurysm with aortocaval fistula.

Clinical Characteristics of Retroperitoneal Fibrosis Patients at a Tertiary Hospital in Japan.

Retroperitoneal fibrosis (RPF) is a rare cause of hydronephrosis and progressive renal dysfunction with unidentified origin. RPF is categorized into idiopathic RPF with/without immunoglobulin G4 (IgG4)-related disease (IgG4-RD), and secondary RPF. Identifying the underlying cause is challenging and often associated with delayed diagnosis or therapeutic interventions.

Radiomics Analyses to Predict Histopathology in Patients with Metastatic Testicular Germ Cell Tumors before Post-Chemotherapy Retroperitoneal Lymph Node Dissection.

Background: The identification of histopathology in metastatic non-seminomatous testicular germ cell tumors (TGCT) before post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) holds significant potential to reduce treatment-related morbidity in young patients, addressing an important survivorship concern.

Aim: To explore this possibility, we conducted a study investigating the role of computed tomography (CT) radiomics models that integrate clinical predictors, enabling personalized prediction of histopathology in metastatic non-seminomatous TGCT patients prior to PC-RPLND. In this retrospective study, we included a cohort of 122 patients.

[IgG4-related disease: A proteiform pathology with frequent chest manifestations].

Introduction: While IgG4-related disease (IgG4-RD) was initially described in the early 2000s, its polymorphic clinical manifestations were previously reported under different names ; they have in common the presence of IgG4+ oligoclonal plasma cells and fibrosis.

State Of The Art: Ruling out certain differential diagnoses, the diagnosis of IgG4-RD is based on a bundle of clinical, biological and histological features. Chest involvement is variable and can affect the mediastinum, bronchi, parenchyma, pleura and/or, more rarely, bones and (pericardium, aorta, coronary…) vascular structures.

Significant association of CX3CR1+CD8 T cells with aging and distinct clinical features in Sjögren's syndrome and IgG4-related disease.
