An urinoma(uriniferous pseudocyst, pararenal pseudocyst) denotes an encapsulated collection of urine in the perirenal or paraureteral space. It was usually reported in relation to trauma and acquired obstructive uropathy but rarely reported in renal infection including renal candidiasis. The mechanism is believed due to rupture of fornix through weakened portion of suppurated kidney and pyelosinus backflow by increased intrapelvic pressure in obstructive uropathy and fungus ball obstruction. We report a case of urinoma in a premature as the first case in Korea which developed as a complication of renal candidiasis.

Spontaneous intraperitoneal extravasation of urine is rare. Perirenal urinoma may develop when obstruction to urinary flow creates sufficient back pressure to produce extravasation of urine. Urinary ascites most commonly indicate a disruption to the integrity of the urinary tract. We report a case of urinary ascites with urinoma resulting from an ureteropelvic junction obstruction in a neonate.

Urinomas can occur after renal trauma or perforation of the collecting system during an endosurgical procedure. However, spontaneous urinomas are very rare. Here we report a case of a spontaneous perinephric urinoma following the removal of a Foley catheter in an 18-year-old girl with acute kidney injury caused by septic shock. The patient had been treated for septic shock, acute kidney injury, and acute respiratory distress syndrome, and had a Foley catheter in place for seven days. After Foley catheter removal, the patient complained of consistent voiding difficulty. An abdominal computed tomography scan showed a large amount of left perinephric fluid, and the aspirated fluid included urothelial cells, confirming the diagnosis of a urinoma. The urinoma was successfully treated by insertion of a double-J stent into the left ureter. This report discusses the available literature on urinomas, and their clinical features, diagnosis, and treatment.

Urinothorax occurs when urine leakes into thoracic cavity and it was first reported by Correie in 1968. The mechanism of its occurrence is an accumulation of urine in thoracic cavity by retroperitoneal urinoma formed by urinary tract obstruction or trauma. Retroperitoneal inflammation, malignant neoplasm, kidney transplantation, and kidney biopsy can also induce urinothorax. The diagnosis of urinothorax may be delayed due to its rare incidence rate, but if diagnosis is confirmed the treatment is possible by urinary diversion. We report our experience of a case of urinothorax associated with retroperitoneal urinoma followed by blunt renal trauma with review of literatures.

Renal injuries occur in more than 10% of patients who sustain blunt abdominal injuries. Non-operative management (NOM) is the established treatment strategy for lowgrade (I-III) renal injuries. However, despite some evidence that NOM can be successfully applied to high-grade (IV, V) renal injuries, it remains unclear whether NOM is appropriate in such cases. The authors report two cases of high-grade renal injuries that underwent NOM after embolization in a hybrid emergency room (ER) system with a 24/7 in-house interventional radiology (IR) team. A 29-year-old male visited Wonkwang University Hospital Regional Trauma Center complaining of right abdominal pain after being hit by a rope. Computed tomography (CT) was performed 16 minutes after arrival, and the CT scan indicated a grade V right renal injury. Arterial embolization was initiated within 31 minutes of presentation. A 56-year-old male was transferred to Wonkwang University Hospital Regional Trauma Center with a complaint of right flank pain. He had initially presented to a nearby hospital after falling from a 3-m height. Thanks to the key CT images sent from the previous hospital prior to the patient's arrival, angiography was performed within 8 minutes of the patient's arrival and arterial embolization was completed within 25 minutes. Both patients were treated successfully through NOM with angioembolization and preserved kidneys. Hematoma in the first patient and urinoma in the second patient resolved with percutaneous catheter drainage. The authors believe that the hybrid ER system with an in-house IR team could contribute to NOM and kidney preservation even in high-grade renal injuries.
