Multiple cystic disease occurring in the diseased kidneys of patients with end-stage renal insufficiency is called uremic acquired cystic disease of the kidney. In male patients undergoing long-term hemodialysis the incidence of ACDK is markedly high. ACDK is known to be accompanied by tumor, bleeding, calculus, abscess, etc., and the complication of cancer of the kidney is a special problem. In patients undergoing hemodialysis, occurrence of ACDK, tumor, and kidney cancer are observed respectively at the rate of 47.1, 4.8, and 1.5 per cent. When hemodialysis patients show gross hematuria, flank pain, rapid decrease in hematocrit, and sustained fever, ACDK or its complications should be investigated. Since the risk accompanied by kidney cancer is high in spite of a lack of symptoms, regular screening by ultrasonic examination or CT scan is needed. Renal transplantation is also recommended because of the regression of ACDK after successful renal transplantation. In the future, it appears that ACDK should be considered one disease entity and added to the categories of renal cystic diseases. In addition, ACDK can be studied as a model for clarification of the mechanism of cyst and tumor occurrence.

A case of transitional cell papilloma of the ureter is reported in a seven-year-old boy who had a history of left flank pain, involuntary voiding and nocturnal enuresis, and was found to have ureterohydronephrosis of a solitary left kidney and renal insufficiency. Renal function and morphology were restored by cutaneous loop ureterostomy, neoureterocystostomy and ureterostomy closure in a staged repair.

The authors report two cases of puerperal right ovarian vein thrombophlebitis (POVT) with floating thrombus in the inferior vena cava (IVC). The originality of this report lies in the first line surgical treatment approach. POVT is recognized as presenting usually within the first week post-partum after about 0.05% of deliveries. The syndrome consists of lower abdominal or flank pain, unexplained fever and a tender abdominal mass. Abdominal or pelvic findings are often scanty. In some cases, the thrombus may extend to the inferior vena cava, leading to the risk of pulmonary embolism or low grade renal insufficiency. Diagnosis has been difficult in the past. Since acute appendicitis is the commonest differential diagnosis, laparotomy is frequent. CT scan provides a readily available, accurate, non invasive technique for the diagnosis of POVT. Criteria are: enlargement of the vein, a low density lumen within the vessel wall and a sharply defined vessel wall enhanced by contrast media. The treatment of POVT is initially medical. Antibiotics should be given to cover the commonest infecting organisms. Heparin should also be prescribed at therapeutic IV doses to be followed by oral anticoagulants for at least six weeks. Surgery is usually only recommended when the patient remains symptomatic despite proper medical management, develops clinical, scan or arteriographic evidence of pulmonary embolism, or cannot be anticoagulated. The recommended surgical technique is to clamp the anastomosis of the ovarian vein with the vena cava.(ABSTRACT TRUNCATED AT 250 WORDS)

The incidence of tuberculosis has risen in many parts of the world, and more attention is being focused on genitourinary tuberculosis (GT), the second most common extrathoracic form of tuberculosis. Although chemotherapy is the mainstay of treatment, ablative surgery as a first-line management may be unavoidable for sepsis or abscesses. In cases with hydronephrosis and progressive renal insufficiency caused by obstruction, renal drainage (by stenting or nephrostomy) must be performed immediately. In all other situations triple-drug chemotherapy should be undertaken for at least 6 months and stable conversion obtained before ablative or reconstructive surgery is planned. Nephrectomy or partial nephrectomy is indicated for nonfunctioning or poorly functioning kidneys, particularly if continuous flank pain or hypertension is present. Stenosis of the ureter usually can be managed by temporary stenting and adjuvant corticosteroid therapy. Today the indications for augmentation are rare, but bladder replacement may be combined with ureter replacement using segments of intestine.

Renal insufficiency or allergic reactions for X-ray contrast agents are frequent limitations in immunocompromised hosts such as neutropenic or AIDS patients. Due to a better tolerance of contrast agents in MRI, this technique is well suited for investigation of parenchymal organs. We demonstrate an allergic AIDS patient who presented with fever and flank pain. At sonography, anechoic renal lesions were supposed to be non-complicated cysts; however, on T2-weighted MRI, the center was of high signal. Dynamic contrast-enhanced MRI of the kidneys demonstrated an enhancing rim with ill-defined margins. The lesions were supposed to be multiple bilateral abscesses. Due to the multiple dynamic contrast series, a delayed enhancement of renal parenchyma was detectable adjacent to the lesion. This was suggested as accompanying local pyelonephritis and an infectious etiology became more reliable. Aspergillus fumigatus was identified by CT-guided biopsy as the underlying microorganism. The MR appearance of this manifestation has not been described previously.

Indinavir sulfate has been reported to cause asymptomatic crystalluria and nephrolithiasis in patients with human immunodeficiency virus (HIV) infection. Patients taking indinavir may present with asymptomatic crystalluria, nephrolithiasis with frank renal colic and obstruction, flank pain in the absence of nephrolithiasis, and dysuria or urgency. Asymptomatic crystalluria has been described as benign. Discontinuation of the drug has not been recommended in the absence of nephrolithiasis. We report two HIV-positive patients receiving indinavir who developed acute interstitial nephritis with foreign body giant cell reaction on renal biopsies. Both patients had asymptomatic crystalluria, although crystals were associated with clumps of white blood cells (WBCs) on urinalysis in one patient. Both cases show that the inflammatory response was significant enough to lead to tubular injury and acute renal impairment. Our findings suggest that asymptomatic crystalluria attributable to indinavir may illicit an inflammatory response with acute renal insufficiency, warranting monitoring of renal function, especially in patients with crystalluria.

A 51-year-old female patient was hospitalized in our department with high fever and left flank pain. Laboratory examination showed leukocytosis, increase of C-reactive protein (CRP), hyperglycemia and renal insufficiency. Enterobacter aerogenes grew out of the cultured urine. The radiograph and computerized tomographic (CT) scan revealed streaky gas in the destroyed left renal parenchyma with perirenal gas. She was diagnosed with left emphysematous pyelonephritis. Antibiotics therapy, treatment for sepsis and disseminated intravesicular coagulation was initiated resulting in mitigation of inflammation. High blood glucose initially required insulin therapy, but finally returned to normal levels through administration of oral antidiabetics. Although leukocytosis and low grade fever continued, the patient was discharged on day 53 with a negative CRP. CT scan indicated that the emphysematous change was localized after three months and almost resolved after four months. Renal scintigram indicated the residual function of the affected kidney. Because of the possibility of residual renal function and the cure by conservative therapy alone, the conservative therapy is preferred when the initial treatment is effective.

Ultrasound has emerged as the primary imaging modality in conditions where either renal obstruction or renal medical disease is suspected on the basis of clinical and laboratory findings. In urinary tract obstruction, pathophysiologic changes affecting the pressure in the collecting system and kidney perfusion are well understood and form the basis for the correct interpretation of real-time US and color Doppler duplex sonography (CDDS). Ultrasound is very sensitive for the detection of collecting system dilatation ("hydronephrosis"); however, obstruction is not synonymous with dilatation, as either obstructive or nonobstructive dilatation may be present. To differentiate these conditions, CDDS with measurement of the resistive index (RI) in the intrarenal arteries is extremely helpful, as obstruction (except in the peracute stage) leads to intrarenal vasoconstriction with a consecutive increase of the RI above the upper limit of 0.7, whereas nonobstructive dilatation does not. Diuretic challenge to the kidney may further enhance these differences in RI between obstruction and dilatation. Based on these findings, the present value of US and CDDS in the assessment of the patient with flank pain or renal colic is suggested, especially with respect to promising results for spiral CT and based on cost analysis. In renal medical disease, distinguishing different pathologic conditions using gray-scale US and CDDS (RI) criteria is still very difficult. Nevertheless, US is the fist-line imaging modality in the patient with renal insufficiency.

A 51-year-old HIV-positive man treated with atazanavir for 9 months presented with anuria following right flank pain. Laboratory examination indicated renal insufficiency, and abdominopelvic computed tomography scanning showed bilateral hydroureteronephrosis, but no stones were visualized. Endoscopic procedures were performed to investigate the causes of ureteral obstruction and, if possible, to insert Double-J stents in the ureters. A yellowish stone composed of pure atazanavir was found at the right ureteral orifice, and retrograde pyelography revealed a filling defect in the left ureter found to be caused by an atazanavir stone. The patient's renal function recovered after removal of these stones.

Diffuse bilateral infiltration of the kidneys by lymphoma is probably the rarest cause of renal insufficiency. Moreover, acute renal failure as the initial manifestation of the lymphoma is reported only in a few cases. A 44-year-old man complaining of bilateral flank pain and weakness for 2 months was admitted with acute renal failure. Ultraonography revealed hyperechoic bilaterally enlarged kidneys and an enlarged spleen. Fat pad aspiration was negative for amyloidosis and serum protein electrophoresis was normal. Needle biopsy of the kidney and pathologic examination showed diffuse infiltration of the interstitium with lymphocytes and atypical cells. Bone marrow aspiration and biopsy were negative for malignant cells. Open kidney biopsy was performed and infiltrated cells positive for CD20 and negative for CD3 markers were observed based upon which diagnosis of diffuse large B-cell type non-Hodgkin lymphoma was made.
