Spontaneous rupture of the kidney involves either the collecting system or parenchyma, the latter being associated with a subcapsular or perirenal hematoma. A review was made of 78 cases of spontaneous parenchymal rupture with perirenal hematoma, including 4 of our own. One of these cases is the first description of spontaneous rupture of the kidney secondary to renal vein thrombosis. The patients are usually in the fourth decade of life and present with an acute onset of flank pain, a tender mass and commonly symptoms and signs of shock. Hematuria is often present and generally urography reveals a mass, distorted collecting system and/or non-visualization of the kidney. Tumors are the most common cause followed by vascular diseases, infection, nephritis and blood dyscrasias. Nephrectomy when possible should be performed expeditiously since conservative therapy is uniformly unsuccessful.

Acute focal bacterial nephritis refers to a renal mass caused by acute focal infection. We report a case of acute focal bacterial nephritis, herein. The case was in a 56-year-old woman, who was hospitalized with the chief complaint of left flank pain, chills and fever. Intravenous pyelography suggested the presence of a mass in the upper pole of the left kidney. Ultrasonography showed a hypoechoic mass, CT scan revealed a round, low density mass. Antibiotic therapy resulted in resolution of symptoms, and a follow-up CT scan and ultrasonography showed complete resolution of the renal mass.

The incidence of renal vein thrombosis (RVT) and other thrombo-embolic phenomena was evaluated in 44 unselected patients with nephrotic syndrome. Renal vein thrombosis was demonstrated by selective renal venography in 10 patients and at post-mortem in one. Extension of the thrombus from the renal veins into the inferior vena cava was seen in 3 patients. Evidence of thrombo-embolism elsewhere in the body was seen in the form of thrombophlebitis in the lower extremities in 4 patients (9.1%), pulmonary embolism in 3 (6.8%) and myocardial infarction in one (2.3%). Of the 11 patients with RVT, renal histology showed membranous glomerulonephritis in 3, minimal change nephritis in 5, membrano-proliferative in one and focal and diffuse proliferative glomerulonephritis in one patient each. The characteristics clinical findings such as gross haematuria and flank pain were noted in only 3 patients with RVT. No significant difference could be detected between the plasma fibrinogen, serum cholesterol, beta-lipoprotein, triglycerides and phospholipid concentration of those who showed RVT and the remainder in whom RVT was not demonstrated. The possible mechanisms involved in the pathogenesis of RVT in nephrotic syndrome are discussed.

A case of spontaneous renal rupture with subcapsular hematoma was reported. The patient was a 44-year old man complaining of a sudden left flank pain without any recent history of trauma. His abdominal ultrasonography (US), computerized tomography (CT) and renal angiography demonstrated left renal rupture with subcapsular renal hematoma. Cytological examination of left upper urinary tract revealed a suspicion of a neoplasma of renal pelvis and left renal function was not recovered. Therefore, left total nephro-uretectomy was performed, and histological examination revealed hemorrhage and infarct due to the severe arteriosclerosis and intestinal nephritis without malignancy. Sixty-three cases of non-traumatic subcapsular renal hematoma reported previously in the Japanese literature are reviewed with some statistical analyses.

Percutaneous renal biopsy (PRB) is now standard practice in clinical nephrology. One hundred consecutive non-transplant PRBs performed on adult patients at the Department of Renal Medicine, Singapore General Hospital, between January and August 1990, were analysed to examine the impact and complications of PRBs in a single institution. The study population consisted of 37 male and 63 female patients with a mean age of 32 +/- 11.9 years. The most frequent indications for PRB were systemic lupus erythematosus with renal involvement (41 patients), haematuria and proteinuria (27 patients) and the nephrotic syndrome (26 patients). Histological diagnoses included lupus nephritis in 45 patients, IgA nephritis in 19 patients, minimal change/focal global sclerosis in 14, non-IgA mesangioproliferative glomerulonephritis in seven and other histologies in the remainder. Eighty-two of our patients received renal-specific therapy, including 72 who received prednisolone or other immunosuppression, and 11 who received persantin and warfarin, in contrast to only 18 patients who received non-specific therapy including diuretics, antihypertensive drugs or dialysis. PRB led to change in therapy in 54% of all our patients, including 42 who had immunosuppressive drugs added to their therapeutic regimen and 11 who were commenced on persantin and/or warfarin. Complications of the procedure were minimal with flank pain in 6% and gross haematuria in 4%. As the inherent risks of inappropriate immunosuppression are well established, these results suggest that PRBs have a major impact on clinical management.

Acute lobar nephronia (ALN), a term analogous to acute lobar pneumonia, refers to a renal mass caused by acute focal infection without liquefaction. An alternative term is acute focal bacterial nephritis (AFBN). Fever, flank pain or back pain are the most frequently encountered clinical characteristics. Imaging modalities used to establish a definite diagnosis of acute lobar nephronia included sonography, computed tomography and nuclear medicine. Uroradiographic findings in this condition can mimic a renal abscess or neoplasm. Further distinction between acute lobar nephronia and other renal masses is aided by the appropriate use of renal sonography and computerized tomography is the most effective and least costly method in diagnosis. Serial sonograms can be used to monitor response to antibiotic therapy. Clinical and uroradiographic characteristics of a six year-old female patient with acute lobar nephronia are presented, along with a review of literature.

We describe an unusual complication of acute pyelonephritis in a 45-year-old diabetic female. She was admitted to our hospital due to fever and flank pain which had developed 10 days earlier. Urinalysis showed many WBC and urine culture revealed Escherichia coli. After adequate antibiotic treatment, clinical symptoms abated but renal failure and leukocyturia persisted. Abdominal CT showed bilateral focal bacterial nephritis and renal biopsy disclosed chronic granulomatous interstitial nephritis. On the 80th hospital day she was discharged with a serum creatinine of 299 mumol/l. In the outpatient clinic, renal dysfunction and leukocyturia persisted up to 1 year. In conclusion, this case raises the possibility of a chronic interstitial process of acute pyelonephritis.

Acute lobular nephritis is a focal bacterial infection localizer within the parenchyma of the kidney which may develops with abscess formation; clinical features of such evolution include, fever, chills, flank pain and the hematological findings of infective disease. Echographic pattern includes a law-level echogenic mass with a central hypoechoic or echo-free with sometimes may deform renal profile. Clinical picture and echographic pattern allow the diagnosis of acute lobular nephritis. In the present work we report 3 cases of lobular nephritis on which ultrasound study has permitted the correct diagnosis equally to TC and RM which also was performed. Furthermore the ultrasound imaging is a valid method to appreciate the clinical evolution of patient during therapy.

We report a case of acute focal bacterial nephritis (AFBN). A 30-year-old female patient visited Kyushu Rosai hospital with complaints of right flank pain and a fever of 3 days duration. She was immediately admitted, but still suffered from flank pain after 3 days of antibiotic therapy. Abdominal CT scan detected a focal mass lesion in the mid portion of the right kidney. Her clinical symptoms improved after 7 days of chemotherapy, and she was discharged. The mass lesion in the kidney disappeared after one month, she remained free of symptoms, and renal function was normal when followed up nineteen months later.

A 56-year-old male with DM and HTN presented with flank pain and nausea. Review of systems was negative, physical examination was notable for mild hypovolemia and laboratory revealed BUN 51 mg/dl, creatinine (Cr) 5.1 mg/dl (baseline 1.5), Westergren ESR 122 mm/h, fractional excretion of sodium 0.2% and UA positive for blood and protein. Despite volume resuscitation the Cr continued to rise. Urine sediment analysis revealed granular casts, renal tubular epithelial cells and a negative Hansel's stain. Hemodialysis was initiated with Cr 13.7 mg/ dl for dyspnea and dysgeusia. Subsequent laboratory data revealed 2 separate positive anti-GBM antibody titers and prednisone therapy was initiated. Renal biopsy was performed for further diagnostic, therapeutic and prognostic information and demonstrated interstitial nephritis with linear IgG and albumin deposition consistent with diabetic nephropathy. Follow-up antibody titers were negative. prednisone was discontinued and Cr stabilized with conservative therapy. Anti-GBM antibody disease is characterized by circulating IgG antibodies directed against the glomerular basement membrane, specifically the alpha-3 (IV) collagen chain. Anti-GBM nephritis is a rapidly progressive, isolated glomerulonephritis in association with circulating anti-GBM antibodies. A positive immunofluorescence (IF) test is considered diagnostic in the appropriate clinical setting. Therapies include immunosuppressive agents to suppress new antibody production and plasmapheresis to eliminate circulating antibodies. Anti-GBM antibody is not rapidly cleared by steroid therapy and the recovery of renal function is rare if initiation Cr is greater than 7 mg/dl. This case demonstrates that the current ELISA for alpha-3 (IV) collagen is not pathognomonic for anti-GBM nephritis and that renal biopsy with IF for IgG and albumin may be indicated to prevent administration of potentially toxic treatment.
