The manifestations, clinical course and treatment of 14 patients with non-malignant renal vein thrombosis are described. Most patients (10 of 14) had generalized vague illness and nephrotic syndrome but 4 were initially seen with acute symptoms of flank pain, hematuria or hypertension. Renal vein thrombosis affected young men 2.5 times more often than women and occurred on the left side 2.6 times more commonly than on the right or both sides. Red blood cell casts in the urinary sediment, heavy proteinuria and hypoalbuminemia were useful indicators of the disease. Excretory urographic signs were suggestive of renal vein thrombosis in all patients and these were corroborated by angiographic studies. Systemic anticoagulation with or without a renal failure program and diuretics, or simply a combination of the last 2 modalities, was used in 9 patients. In 2 of the 9 patients who were unresponsive the adjuvant use of cyclophosphamide and steroids effected a cure. The remaining 5 patients underwent nephrectomy or thrombectomy. All 14 patients were followed for 1 to 7 years (mean 1.6 years). Ten patients were cured or improved, 1 patient was unchanged, and in the remaining 3 patients the condition deteriorated and they subsequently required a renal allograft. The rationale for various forms of treatment is discussed.

We report 2 cases of spontaneous thrombotic occlusion of the main renal vessels presenting with acute lumbar flank pain and hematuria suspect of nephrolithiasis. Clinical and laboratory signs of blood hypercoagulability, generalized arterial embolism, nephrotic syndrome or glomerulonephritis were absent. Excretory urography, nephrosonography and retrograde ureteropyelography showed no evidence of upper urinary tract calculi or other causes of obstruction. Renal angiography and cavography demonstrated an acute renal vein thrombosis in 1 patient and a thrombotic occlusion of all but one of the segmental renal arteries in the other patient. These 2 cases demonstrate that thrombotic occlusion of the renal artery or renal vein has to be considered in patients who are presenting with lumbar flank pain and hematuria, in whom the excretory urogram shows severe malfunction of one of the kidneys, and stone disease can be excluded. Renal angiography and cavography as well as CT scan should be carried out in these patients. When the disease is diagnosed at an early stage, an intra-arterial thrombolysis can be attempted.

A case of renal vein thrombosis in a seventy-five year old female was reported. She complained of severe left flank pain. The symptoms and signs resembled obstruction from a ureteral calculus. The kidney-ureter-bladder X-ray showed a calcification in the pelvic cavity. She was admitted under the initial diagnosis of left ureteral stone. The venous phase of renal arteriography revealed venous collaterals (ureteric vein and gonadal vein). Selective renal phlebography demonstrated a radiolucent area. Warfarin, 6 mg orally daily, has been administered for a year. It has effectively prevented subsequent emboli. This was a rare case of renal vein thrombosis in an old patient, because it was not associated with nephrotic syndrome or thromboembolic state and because it presented as sudden onset.

Cases with a pathological diagnosis of renal venous thrombosis (RVT) associated with nephrotic syndrome (NS) were studied retrospectively for clinicopathological evaluation. The material consisted of 21 RVT cases which were diagnosed in 2000 consecutive pediatric necropsies, with an overall incidence of about one percent. Eight of the 21 RVT cases were associated with nephrotic syndrome (34%), and this group formed 0.4 percent of the total necropsies in our pediatric center. The glomerulopathies of these nephrotic patients consisted of three cases of Finnish-type congenital NS (FCNS), three cases of renal amyloidosis secondary to familial Mediterranean fever, and two cases of membranoproliferative glomerulonephritis (MPGN). The presence of sepsis associated with disseminated intravascular coagulation, and the morphological age of the thrombi suggested that the RVT was secondary to sepsis in the FCNS cases. In the MPGN and secondary renal amyloidosis cases, the long duration of both the nephrotic state and the administration of diuretics along with glucocorticoid treatment and also the newly formed thrombi without infarction are strong evidences, although not definite, that the RVT developed as a complication of the glomerulopathy. Even though there were no definite clinical criteria for the diagnosis of most of the RVT cases, we would like to emphasize the importance of flank pain, the rapid deterioration of renal functions in a stable nephrotic patient, as well as the hypercoagulable state in the consideration of the development of RVT which indicate the need for appropriate radiological studies for confirmation of this condition during life.

All nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase, and consequently renal functions dependent upon prostaglandin synthesis can be affected. Fortunately, renal function in normal individuals is relatively independent of the PG system, and thus the NSAIDs don't usually produce any renal dysfunction. However, in some circumstances, inhibition of PG dependent renal functions can produce clinically significant effects. When the kidney is in a salt retaining state or when there is renal vascular damage, NSAIDs can reduce renal blood flow and glomerular filtration rate producing acute renal failure that is reversible upon discontinuation of the drug. NSAIDs can also: 1) reduce sodium excretion and blunt the diuretic effect of loop diuretics, thus producing or exacerbating edema, 2) inhibit PG dependent renin secretion occasionally resulting in hyperkalemia, 3) enhance the antidiuretic effects of vasopressin and 4) reduce the antihypertensive efficacy of several drugs. Evidence that any NSAID "spares" renal cyclooxygenase is controversial, and no NSAID is devoid of clinical problems. Syndromes that are less obviously related to inhibition of renal PG synthesis are acute interstitial nephritis with or without the nephrotic syndrome, renal papillary necrosis, and chronic interstitial nephritis. Recently a unique syndrome of flank pain and mild reversible renal dysfunction has been described in healthy individuals receiving suprofen, a uricosuric NSAID. This syndrome may be due to uric acid crystal deposition in the renal tubules and has resulted in the removal of suprofen from the US market.

Renal vein thrombosis in adults is usually a complication of the nephrotic syndrome. Rarely, it has been reported in nonnephrotic women postpartum. The thrombosis may be a complication of the hypercoagulable state associated with both the nephrotic syndrome and pregnancy. Two postpartum patients with renal vein thrombosis and no prior history of renal disease are reported here. Neither patient had heavy proteinuria. In both cases, pyelonephritis was suspected clinically and the diagnosis of renal vein thrombosis was first suggested and confirmed by radiologic examination. Renal vein thrombosis should be considered in women presenting postpartum with flank pain.

A case of a pre-aortic left renal vein compression by the aorta is reported. The clinical presentation was characterized by the left flank pain varying with body body position. Renal venography was crucial for the diagnosis of this lesion. The left renal vein was successfully decompressed by ovarian vein-vena cava shunt surgery. The patient's left flank pain subsided after the surgery. This is the first reported case of a left renal vein compression syndrome by the aorta following the nephrotic syndrome.

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.

The present study is a prospective evaluation of 151 patients with the nephrotic syndrome in regard to the incidence of renal vein thrombosis, modes of clinical presentation, pathogenetic course and response to anticoagulant therapy. Of the 151 nephrotic patients studied, 33 had renal vein thrombosis and membranous nephropathy was present in 20. There were two modes of clinical presentation: (1) a sudden renal vein thrombosis was observed in the young patient with acute flank pain, marked costovertebral angle tenderness and macroscopic hematuria; a characteristic intravenous pyelogram, renal histologic changes and anticoagulant therapy were followed by marked improvement in renal function; (2) long-term renal vein thrombosis was observed in the older patients; they were asymptomatic and intravenous pyelograms disclosed no abnormalities; there were no suggestive renal histologic findings; the incidence of thromboembolic phenomena other than renal vein thrombosis was high, and there was mild progressive deterioration of renal function which was not altered by anticoagulant drugs; treated nephrotic patients with chronic renal vein thrombosis did not experience a new episode of thromboembolism whereas untreated nephrotic patients without renal vein thrombosis did. Finally, the sequence of nephrotic syndrome leading to renal vein thrombosis was clearly established showing the pathogenetic role of the nephrotic syndrome in renal vein thrombosis. Possible mechanisms in the pathogenesis of renal vein thrombosis are also discussed.

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.
