An 18-year-old man with mild factor VIII deficiency developed hematuria and, subsequently, acute renal failure due to high-grade urinary obstruction by clots during therapy with cryoprecipitate, epsilon-aminocaproic acid, and acetazolamide administered for ocular trauma. Discontinuation of therapy with the latter two agents and induction of a brisk diuresis with intravenous (IV) fluid therapy resulted in return of renal function concomitant with spontaneous clot passage. A review of previous literature suggests that hemophiliacs may be more susceptible than nonhemophiliacs to high-grade urinary obstruction due to clot formation when epsilon-aminocaproic acid is administered during episodes of hematuria. Acute flank pain, fever, and delayed dense nephrograms on IV pyelogram are characteristic of the syndrome and distinguish it from other forms of acute renal failure associated with epsilon-aminocaproic acid.

A 35-year old man was hospitalized for left flank pain. IVP showed left non-visualizing kidney with multiple renal calculi. Selective renal arteriogram revealed avascular mass in the left upper pole. The upper calyx was irregularly distorted. Left nephrectomy was carried out. Grossly, the upper pole was replaced by whitish, firm and homogeneous tumor, which was 7 X 7 cm in diameter and protruded into the upper calyx. Histologically, the tumor was composed of both epithelial and mesenchymal components. The epithelial elements consisted of cysts and tubules, and the mesenchymal elements of loosely textured fibroblasts and smooth muscle cells. Other elements could not be identified. This case was diagnosed as renal hamartoma histologically resembling congenital mesoblastic nephroma of infancy. Congenital mesoblastic nephroma is rare in adults. Continued maturation may finally transform it either to benign mixed tumor as in our case or fibromatous tumor if stroma matures dominantly.

A case of emphysematous pyelonephritis is presented. A 49-year-old male with diabetes mellitus complaining of high grade fever attack and right flank pain was referred from internal medicine. KUB demonstrated that the right ureter, pelvis and calyces were filled with gas. Anti-bioticus was given intensively and the abnormal gas shadow on plain film disappeared before RP was done, but high grade fever attack persisted and right nephrectomy was undergone. After this operation, the fever was relieved and the patient was discharged at the 30th day post-operatively. A search of available literature in Japan has disclosed only 17 reported cases. Diagnostic methods, treatment, complication and etiology are discussed.

Ultrasound examinations were analysed in 24 patients with acute renal infections (pyelonephritis, focal pyelonephritis, renal abscess, pyonephrosis). Ultrasound examination is normal in mild inflammatory involvement of parenchyma, diffuse enlargement of parenchyma with echo-poor structure is found in severe involvement of parenchyma, localized echo-poor swelling of parenchyma is seen in focal pyelonephritis. Fever and flank pain are common to acute ureteral obstruction and acute pyelonephritis and ultrasound can differentiate between these diseases. Among mass lesions ultrasound can distinguish between focal pyelonephritis and abscess but cannot differentiate between tumor and focal pyelonephritis.

Two cases of renal angiomyolipoma with tuberous sclerosis are reported. The first was a 42-year-old housewife with complaints of left flank pain, palpable mass at the same region and in a preshock state. Ultrasonogram of the left kidney demonstrated a large echogenic mass with fluid. Preoperative diagnosis was renal angiomyolipoma with spontaneous rupture. Emergency nephrectomy and lymphadenectomy were performed. The histopathological diagnosis was renal angiomyolipoma with nodal involvements which reflects the multicentricity of the disorder. The second was a 44-year-old housewife with dull right flank pain. CT scan showed a mass in the upper part of the kidney which had an attenuation value of -60 HU. Adrenal tumor could not be distinguished from renal tumor by selective renal angiogram. Nephrectomy was performed and histopathological diagnosis was renal angiomyolipoma. Both cases remain well. We reviewed 32 cases of renal angiomyolipoma with spontaneous rupture in the Japanese literature with respect to age, affected side, presence or absence of tuberous sclerosis, preoperative diagnosis and treatment. Previous diagnoses were done with plain film, excretory urogram and angiogram. Preoperative diagnosis of angiomyolipoma was difficult or impossible, and operative procedure of choice was nephrectomy. Now CT and ultrasonogram are the specific tools in the diagnosis of angiomyolipoma. Partial nephrectomy, enucleation or observation is selected because renal angiomyolipoma is a benign tumor.

Renal angiomyolipoma, a benign tumor, can involve regional lymph nodes. Although this phenomenon has been reported previously followup information has been scant. We have treated 3 patients who had renal angiomyolipoma with nodal involvement and all had further evidence of tuberous sclerosis. Each patient had hematuria with flank pain and required nephrectomy. In the ensuing 3 to 11 years none of these patients has had evidence of further disease progression. Nodal involvement may reflect the multicentricity of angiomyolipoma or may represent a form of "benign metastasis" but it does not appear to be a harbinger of disease progression.

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.

The differentiation between significant mechanical obstruction and nonobstructive dilation of the kidneys and ureters is fundamental to patient management. The diuretic renal scan is a useful test in this situation because it usually is reliable and reproducible and is noninvasive and objective, providing information about the function of each kidney. However, this study has given variable results in a small number of patients. We report our experience with five such patients and recommend an algorithm for evaluating patients with equivocal scan results. This report emphasizes the importance of continued follow-up and the need for periodic reevaluation of patients with unexplained urinary symptoms or persistent flank pain, even when the initial diuretic renal scan is normal.

The simultaneous occurrence of renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) in the same kidney is unusual. We report a 53-year-old man with ipsilateral synchronous renal adenocarcinoma and renal pelvic transitional cell carcinoma with severe hypercalcemia and a huge staghorn calculus in the opposite kidney. The patient was admitted to the hospital because of left flank pain and intermittent fever which he had had for 2 months. Computerized tomography revealed a huge stone in the right kidney and a mass in the upper pole with an irregular calcified pelvis in the left enlarged kidney. Left radical nephrectomy was done. A section of the specimen revealed a renal cell carcinoma located at the upper pole and a papillary transitional cell carcinoma arising from the renal pelvis. This is a rare case of combined renal malignancies.

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.
