Thinking Beyond Acute Kidney Injury.

Case Rep Nephrol Dial 2022 Jan-Apr;12(1):16-21. Epub 2022 Mar 10.

Division of Nephrology, Department of Medicine, University of South Alabama, Mobile, Alabama, USA.

Acute kidney injury (AKI) can be a significant clue to solving a puzzling patient presentation. Postrenal AKI should be suspected if imaging shows any degree of hydronephrosis and can be caused by a variety of conditions. Diagnosis of urinary obstruction without significant dilatation of the pelvic-ureteral system requires a higher degree of suspicion, and hence, its identification can become late. Read More

Difficulties in Diagnosing Extraperitoneal Ureteroinguinal Hernias: A Review of the Literature and Clinical Experience of a Rare Encounter in Acute Surgical Care Settings.

Diagnostics (Basel) 2022 Jan 29;12(2). Epub 2022 Jan 29.

Department of General Surgery, "Victor Babes" University of Medicine and Pharmacy, 300041 Timisoara, Romania.

Although inguinal hernia repair is one of the most common surgical procedures, finding a retroperitoneal structure, such as the ureter, is a rather rare occurrence. Ureteroinguinal hernias may arise in the presence or absence of obstructive uropathy, the latter raising difficulties in diagnosis for the general surgeon performing a regular inguinal hernia surgery. This study aims to collect the relevant literature describing the diagnosis and management of ureteroinguinal hernias and update it with a case encountered in our clinic. Read More

Department of Nursing Faculty, Shree Medical and Technical College, Bharatpur, Nepal.

Introduction: Ureteric calculi are lying at any point of ureter from the pelvic ureteric junction to the vesicoureteral junction. If left untreated, ureteropelvic junction obstruction can lead to hydronephrosis. With the improved availability of computed tomography and ultrasound scanning, hydronephrosis is being diagnosed more frequently. Read More

Acute unilateral hydronephrosis in the setting of hemorrhagic cystitis.

Am J Emerg Med 2022 01 22;51:429.e3-429.e5. Epub 2021 Jul 22.

Jefferson Radiology, East Hartford, CT, United States of America.

Acute flank pain associated with hematuria and unilateral hydronephrosis is a classic presentation for an obstructing ureteral stone. However, in the setting of hemorrhagic cystitis, blood can acutely obstruct the distal ureter and infrequently result in hydronephrosis. We present a case of an adult female patient with hemorrhagic cystitis who presented with acute right flank pain associated with unilateral hydronephrosis and perinephric fluid on point-of-care ultrasound (PoCUS) in the absence of renal or ureteral abnormality on CT scan hours earlier.

Urologiia 2021 Jun(3):56-60

Rostov State Medical University, Rostov-on-Don, Russian Federation.

Introduction: Surgery of the ureterovesical anastomoses lesions in case of weakly-dilated ureters is well developed by the Cohen and Lich-Grgoire techniques.

Pleural effusion and ascites in extrarenal lymphangiectasia caused by post-biopsy hematoma: A case report.

World J Clin Cases 2020 Dec;8(24):6330-6336

Department of Nephrology, The First Hospital of Hebei Medical University, Shijiazhuang 050000, Hebei Province, China.

Background: The renal system has a specific pleural effusion associated with it in the form of "urothorax", a condition where obstructive uropathy or occlusion of the lymphatic ducts leads to extravasated fluids (urine or lymph) crossing the diaphragm innate perforations or lymphatic channels. As a rare disorder that may cause pleural effusion, renal lymphangiectasia is a congenital or acquired abnormality of the lymphatic system of the kidneys. As vaguely mentioned in a report from the American Journal of Kidney Diseases, this disorder can be caused by extrinsic compression of the kidney secondary to hemorrhage. Read More
