“…The proposed mechanism of renal pelvic rupture is a sudden increase in intrapelvic pressure (Csata et al, 1998), and affected kidneys are frequently previously diseased (Caro & Waldbarum 1976, Van Winter et al 1991. In this case, renal pelvic rupture was thought to have occurred secondary to ureterolithiasis, as described in humans (Battista et al 2016, Zhang et al 2017.…”

A neutered female cat presented with a 9-day history of hyporexia and depression. The referring veterinarian had identified moderate non-regenerative anaemia, haematuria and suspected unilateral obstructive ureterolithiasis. Subsequent ultrasonography revealed moderate distension of the left renal pelvis with echogenic material, ureteral distension and ureterolithiasis. A partial ureteral obstruction was suspected. After 4 days of medical management, there was further distension of the renal pelvis with well-delineated echogenic material and an accumulation of perinephric fluid. A left nephroureterectomy was performed. Renal pelvic rupture with intrapelvic haematoma and retroperitoneal haemorrhage was confirmed by histopathology. Eighteen months following surgery, the cat remained clinically well with normal renal values.

“…The rupture site is the fornix, followed by the upper ureter, when pressure exceeds a critical level reported to be from 20-75 mmHg[ 1 ]. The common causes are obstruction (urinary stones[ 2 - 4 ], third trimester of pregnancy[ 5 , 6 ], and papillary necrosis) and urinary retention[ 7 ]. Urinary stones are the most common cause of renal pelvis rupture[ 8 ].…”

BACKGROUND Spontaneous renal rupture is a rare disease in the clinic. The causes of spontaneous renal rupture include extrarenal factors, intrarenal factors, and idiopathic factors. Reports on infection secondary to spontaneous renal rupture and the complications of spontaneous renal rupture are scarce. Furthermore, there are few patients with spontaneous renal rupture who present only with fever. CASE SUMMARY We present the case of a 52-year-old female patient who was admitted to our hospital. She presented only with fever, and the cause of the disease was unclear. She underwent a contrast-enhanced computed tomography (CT) scan, which showed that the left renal capsule had a crescent-shaped, low-density shadow; the perirenal fat was blurred, and exudation was visible with no sign of calculi, malignancies, instrumentation, or trauma. Under ultrasound guidance, a pigtail catheter was inserted into the hematoma, and fluid was drained and used for the bacterial test, which proved the presence of Klebsiella pneumoniae. Two months later, abdominal CT showed that the hematoma was absorbed, so the drainage tube was removed. The abdominal CT was normal after 4 mo. CONCLUSION Spontaneous renal rupture due to intrarenal factors causes a higher proportion of shock and is more likely to cause anemia.

“…In addition, while the moderate ascites that recurred 3 days after the right nephrectomy could be attributed to the spontaneous rupture of the left kidney; this could not be confirmed because the owner refused further examinations of the cat. If the presence of a lymphoplasmacytic inflammation in the kidney had been confirmed, we could have improved the cat's condition or prolonged its life with dietary modification (e.g., hypoallergenic diet) and the administration of high-dose corticosteroids or immunosuppressive drugs (Willard 2003;Zaid et al 2011;Zhang et al 2017).…”

“…A spontaneous renal rupture is defined as the rupture of the renal parenchyma due to the renal pathology (Zhang et al 2017). Possibly reflecting the dysregulation of the immune system, a lympho-Hydronephrosis refers to the dilatation of the renal pelvis and calyces due to a renal or postrenal urinary obstruction that induces the progressive atrophy of the renal parenchyma (Rawlings et al 2003).…”

A seven-year-old male cat that was previously diagnosed with – and treated for – left hydronephrosis due to suspected idiopathic proteinaceous materials in the renal pelvis, presented with a short history of anorexia and vomiting. The abdominal ultrasound revealed bilateral hydronephrosis, and the intravenous pyelography showed a moderate amount of free fluid in the retroperitoneal space at 48 hours. After the nephrectomy, the gross examination of the right kidney revealed a very thin capsule with urine leakage, and the right renal pelvis showed small, black deposits. The histopathology of the right kidney revealed hydronephrosis with compression atrophy, necrosis of the renal cortex/medulla, and a moderate lymphoplasmacytic inflammation. The crystallographic analysis revealed that the black deposits were composed of 100% protein and no minerals. The cat was diagnosed with hydronephrosis and spontaneous renal rupture caused by proteinaceous pelvic materials, secondary to the idiopathic renal lymphoplasmacytic inflammation. In addition to revealing the possibility that immune-mediated renal disease can induce spontaneous renal rupture in cats, this case report demonstrates the utility of imaging for diagnosing and monitoring hydronephrosis, detecting urine leakage, and planning surgery.
