RESUMEN
BACKGROUND: Selecting the smaller kidney for donation has been advocated if there is a size difference of > 10% between the 2 kidneys but has never been prospectively evaluated. With increase in donor nephrectomies, it is important to evaluate this to minimize loss of renal function to donors. METHODS: 75 consecutive donor nephrectomy patients were included in our longitudinal study. The Split Renal Volume (SRV) of bilateral kidneys were measured using contrasted computer tomography scans and patients segregated into 2 groups depending on donated kidney having more (Group 1) or less than (Group 2) 52.5% of SRV. RESULTS: Patients in Group 1 (n = 19) and 2 (n = 56) were of similar age (43.8 vs. 48.3), BMI (22.4 vs. 25.2), sex (57.9 vs. 55.4% women), respectively. Although total kidney volumes were similar in both groups, Group 1 had significantly smaller right kidney volumes (120.4 ± 24.9 vs. 142.7 ± 28.4 mls, p = 0.003). EGFR pre-operatively (116.3 ± 20.8 vs. 106.3 ± 23.8 mL/min/1.73 m2) and at 6-months (65.7 ± 13.3 vs. 66.9 ± 15.5 mL/min/1.73 m2) were not different between groups. However, patients in Group 1 had significantly greater absolute (50.6 ± 14.9 vs. 39.5 ± 14.7 mL/min/1.73 m2) and relative decline (43.0 ± 8.6 vs. 36.3 ± 10.6%) in eGFR at 6 months (p = 0.06, 0.009). CONCLUSION: With a SRV difference of 5% between the 2 sides, removal of the larger kidney for living kidney donation resulted in greater early decline of renal function than kidney donors whose larger or equivalent kidney is preserved.

Thoracic ectopic kidney is a rare developmental anomaly that is the least frequent one among all forms of ectopic kidneys. The condition is generally asymptomatic. If a kidney image is missing on one side in renalor pelvic region in sonographic examination, the possibility of thoracic ectopic kidney should be taken into consideration. For final diagnosis, chest radiography and thorax computerised tomography should be obtained. We herein report a rare case of intra-thoracic kidney accompanied by diaphragm eventration.

OBJECTIVE: We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts. MATERIALS AND METHODS: A prospective series of 74 consecutive patients (average age: 57.6 +/- 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography. RESULTS: The sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group. CONCLUSION: Ethanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.

The right renal artery passing anterior to the inferior vena cava is a rare variant of the normal renal arterial anatomy, and identifying this anomaly is important for the planning of minimally invasive renal surgery. The presence of this precaval right renal artery was detected on the contrast-enhanced CT scan by identifying the right renal artery passing anterior to the inferior vena cava. We report here on a case of a precaval right renal artery as a main supplying artery, and this was incidentally found on CT.

Renal tuberculosis commonly involves the urinary tract and results in multifocal fibrosis and stricture. Rarely, it presents as a renal mass with or without urinary tract abnormality. The radiologic features of this rare pseudotumor have not been sufficiently described in the previous literature, and we now report a case of tuberculosis presenting as an isolated renal mass and multiple hepatic nodules without evidence of associated urinary tract abnormality. The condition mimicked malignant neoplastic disease and occurred in a patient who had undergone chemotherapy for leukemia.

PURPOSE: To determine renal toxicity through changes in renal function after the injection of CT and MRI contrast media into rats in which acute renal failure (ARF) was induced. MATERIALS AND METHODS: To cause acute renal failure, the abdominal cavity of 110 male rats each weighing 250-300 gm was opened via a midline incision under anesthesia. Microvascular clamps were placed on both renal arteries and veins to completely block renal blood flow for 45 minutes, and were then removed, allowing blood flow to return to the kidneys. ARF, defined as a two-fold difference in the creatinine level before ARF and 48 hours after, was successfully induced in 60 of the rats. These were divided into two groups: one was injected with CT contrast medium and the other with MRI contrast medium. Each CT and MRI group was divided into a low dose (0.5 cc/kg, 0.2 ml/kg), standard dose (2 cc/kg, 0.8 ml/kg), and high dose (8 cc/kg, 3.2 ml/kg) sub-group; thus, there was a total of six groups with ten rats in each. Blood samples were obtained before ARF, 48 hours after, and 48 hours after contrast injection, and CT scanning and MRI were performed after blood sampling at 48 hours. In each group, creatinine levels 48 hours after contrast injection were compared by means of the ANOVA test. RESULTS: There were no significant differences in creatinine levels between the CT and MRI contrast medium groups (p=0.116), nor between the animals to which different doses of CT and MRI contrast medium, were administered. After both standard and high doses, CT and MRI provided good images. CONCLUSION: In rats in which acute renal failure was induced, renal function did not change according to whether CT or MRI contrast medium was injected. Thus, the two media induce similar levels of toxicity.

A perirenal hematoma very commonly occurs after trauma. Treatment differs according to the degree of renal injury, though many cases are managed conservatively and complications are rare. We report two cases in which successful treatment of a perirenal hematoma involved percutaneous catheter drainage; in one there was bowel obstruction, and in the other the hematoma was infected.

PURPOSE: The purpose of this study was to evaluate the CT findings of acute pyelonephritis (APN) in children and to assess the correlation between these findings, clinical parameters and renal scar development, as seen on follow-up CT scans. MATERIALS AND METHODS: Contrast-enhanced CT scans of thirty children in whom APN had been diagnosed were assigned to one of three groups according to whether an abscess had formed, and then to subgroups on the basis of the number of lesions in the renal parenchyme. Initial CT findings were retrospectively correlated with five clinical parameters (maximal body temperature, fever duration, leukocytosis, pyuria and admission period) and renal scar development, as seen on follow-up CT (n=12). RESULTS: CT scans demonstrated linear, wedge-shaped, low-density renal parenchymal lesions in 35 kidneys of 25 patients and abscesses in seven kidneys of seven patients, but no abnormal lesions in five patients. In the three groups there was correlation between these findings and some clinical parameters (maximal body temperature, fever duration and admission period), but no subgroup showed significant correlation with any clini-cal parameter. Renal cortical scars detected by follow-up CT were more prevalent in patients in whom initial CT demonstrated the presence of an abscess. CONCLUSION: Clinical parameters correlated with the presence of renal parenchymal hypoenhancing lesions and abscess formation, as seen on CT scans, rather than the number of renal parenchymal lesions. Renal cortical scars were more prevalent in patients in whom initial CT revealed the presence of an abscess. Enhanced CT is thought to be useful both for diagnosing APN and for predicting its clinical course in children.

PURPOSE: To assess the usefulness of CT scanning in the differentiation of stage T3a from T2 in renal cell carcinoma. MATERIALS AND METHODS: Among patients with pathologically proven renal cell carcinoma, 114 at stages T2 and T3a were divided into three groups, as follows: intact capsule (T2) n=40, capsular involvement (T2) n=38, and capsular penetration (T3a) n=36. By referring to contrast-enhanced CT scans, we retrospectively compared the groups in terms of tumor margin, the frequency with which a tumor bulged more than 3 cm beyond the renal contour, the presence or absence of peritumoral collateral vessels, thickening of Gerota 's fascia, and perinephric strands. RESULTS: An irregular margin was more common in the capsular penetration group than in the other two groups (p0.05). CONCLUSION: In determining the tumor stage of renal cell carcinoma, CT is not helpful in differentiating between a tumor with capsular penetration (T3a) and one with capsular invasion (T2), though differentiation of the T3a stage from the T2 stage, without capsular invasion, is reliable. When a tumor has an irregular margin, however, the possibility that it is at stage T3a should be considered.

PURPOSE: To define the imaging patterns of xanthogranulomatous pyelonephritis (XGP). MATERIALS AND METHODS: The demographic, clinical, and imaging findings of 21 cases of pathologically proven XGP in 20 patients (bilateral in one) were evaluated. The findings of ultrasonography and CT were retrospec-tively evaluated with regard to distribution and extent of the disease, kidney size, the presence of calculi, hy-dronephrosis, and renal function. The findings were assessed by two radiologists, who established a consen-sus. Imaging and pathologic findings were compared. RESULTS: Sixteen of the 20 patients were female, and 19 were adults. Their age ranged from 3 to 61 (mean, 45) years. In all patients except one, the disease was unilateral (right: left=13:16). In one patient, XGP was bilater-al, and there were thus 21 cases. Seventeen (81%) of these were diffuse, and four (19%) were focal; extrarenal extension occurred in 13 cases (62%), among which ipsilateral pleural effusion was noted in two. The kidney was enlarged diffusely in 12 cases (57%), and focally in three (14%); urinary calculi were present in 16 cases (76%), with staghorn calculi in four of these; and hydronephrosis occurred in 17 (81%). Impairment of ipsilat-eral renal function was noted in 13 cases (62%). Clinical findings of inflammation such as fever, pyuria, bac-teriuria, or leucocytosis were noted in all patients. CONCLUSION: In addition to nephromegaly, renal function impairment, and urinary obstruction due to calculi, which are typical features of XGP, the condition may also show variable imaging findings. If the images ob-tained in the case of a middle-aged woman with clinical findings of urinary infection are atypical, we believe that XGP should be included in the differential diagnosis.

PURPOSE: To correlate the degree of renal cortical enhancement, objectively evaluated by means of spiral CT, with the serum level of creatinine, and to determine the extent to which this degree of enhancement may be used to detect renal parenchymal disease. MATERIALS AND METHODS: Eighty patients [M:F=50:30; age=25 -90 (mean, 53) years] with available serum level of creatinine who underwent spiral CT between September and October 1999 were included in this study. In fifty patients the findings suggested hepatic or biliary diseases such as hepatoma, biliary cancer, or stone, while in thirty, renal diseases such as cyst, hematoma, or stone appeared to be present. Spiral CT imaging of the cortical phase was obtained at 30 -40 seconds after the injection of 120 ml of non-ionic media at a rate of 3ml/sec. The degree of renal cortical enhancement was calculated by dividing the CT attenuation number of renal cortex at the level of the renal hilum by the CT attenuation number of aorta at the same level. The degree of renal cortical enhancement was compared with the serum level of creatinine, and the degree of renal cortical enhancement in renal parenchymal disease with that of the normal group. Among eighty patients there were five with renal parenchymal disease and 75 with normal renal function. RESULTS: The ratio of the CT attenuation number of renal cortex to that of aorta at the level of the renal hilum ranged between 0.49 and 0.99 (mean, 0.79; standard deviation, 0.15), while the serum level of creatinine ranged between 0.6 and 3.2 mg/dl. There was significant correlation (coefficient of -0.346) and a statistically significant probability of 0.002 between the ratio of the CT attenuation numbers and the serum level of creati-nine. There was a significant difference (statistically significant probability of less than 0.01) between those with renal parenchymal disease and the normal group. CONCLUSION: The use of spiral CT to measure the degree of renal cortical enhancement provides not only an effective index for estimating renal functional status but also a means of differentiating between patients with renal parenchymal disease and those who are normal.

PURPOSE: To assess the clinical usefulness of the Bosniak classification system for characterizing cysticrenal masses by computed tomography (CT). MATERIALS AND METHODS: The CT scans of 28 patients with 32pathologically proven cystic renal masses (17benign, 15 malignant) were reviewed retrospectively by tworadiologists, who reached a consensus. Both unenhanced and enhanced CT scans were obtained using thin sectionswith 5-mm or 7-mm collination in 26 and four patients, respectively. Renal masses were categorized using theBosniak classification system; category I and II masses were considered benign, and category IV, malignant. Massesin category IIF or III were considered malignant when their wall thickness was more than 3 mm, their inner wallwas irregular or nodular, their septae were irregular, nodular or thick (more than 2-3 mm), calcification wasextensive, nodular or thick (more than 2-3 mm), and/or solid portions were enhanced more than 10-20 Hounsfieldunit. They were then correlated with their pathologic findings. RESULTS: For cystic renal masses, the finalpathologic results were as follows : all seven category I lesions were benign, as were seven of eight category IIlesions ; seven of 11 category III lesions were malignant, as were all seven category IV lesions. Distinguishingcategory II and III lesions by the Bosniak classification was difficult in two cases. One malignant tumor wasinterpreted as benign, and two benign tumors as malignant. With regard to prediction of the malignancy of 32cystic renal masses, as seen on CT, sensitivity, specificity, and accuracy were 93%, 88%, and 91%, respectively. CONCLUSION: Overall, the Bosniak classification system is useful for the evaluation and management of cystic renalmasses; however, with regard to the distinction between category II lesions requiring conservative management andsurgical category III lesions, some difficulties still remain.

PURPOSE: To assess the effect of hydration status on renal medullary attenuation and to evaluate the incidence of dense renal medulla, as seen on unenhanced CT. MATERIAL AND METHODS: We prospectively studiedunenhanced CT scans of 12 healthy volunteers. Obtained done after 10 hours and 15 hours of dehydration and afteroral intake of 2L of water. BUN/Cr, urine specific gravity, urine osmole and hematocrit were evaluated after 10hours of dehydration. CT images were reviewed for the presence of dense renal medulla and differential attenuationof dense renal and isodense medulla and cortex at the same level. The density changes of renal medulla afterhydration were evaluated. and CT findings were compared with the results of biochemical studies. In addition, weretrospectively reviewed the CT scans of 200 consecutive patients for evaluation of the incidence of dense renalmedulla. RESULTS: In 8 of 12 volunteers, dense renal medulla was seen on CT scan after dehydration. Meanattenuation was 71.3 +/-10.42HU after 10 hours of dehydration, 68.6 +/-13.54HU after 15 hours, and 34.5 +/-11.47HUafter hydration. No significant attenuation differences were detected between 10 hours and 15 hours ofdehydration, but significantly lower attenuation values were noted after hydration. For isodense medulla, the meanattenuation value was 35.7 +/-7.9HU after 10 hours of dehydration, 39.58 +/-9.66HU after 15 hours, and 36.58+/-7.77HU after hydration. The mean attenuation values of cortex were 35.9 +/-5 . 9 5 H U after 10 hours ofdehydration, 37.58 +/-5.95HU after 15 hours, and 37.08 +/-9.75HU after hydration. With regard not only to durationof dehydration, but also ti hydration, no differences in attenuation values were noted for renal cortex orisodense renal medulla. However, higher density was noted in dense renal medulla than in isodense medulla orcortex for the same duration of dehydration. After hydration, complete resolution was seen at five of eight sitesand incomplete resolution at three of eight sites. There was no correlation between CT attenuation and laboratoryresults. Dense renal medulla was seen in 17 of 200 consecutive patients. Mean attenuation values were 64.06+/-8.38HU for dense renal medulla, 37.15 +/-8 . 4 4 H U for isodense renal medulla and 35.36 +/-8.13HU for cortex. CONCLUSION: For the same duration of dehydration, dense renal medulla showed a higher attenuation value thanisodense medulla or cortex, a finding which was completely or incompletely resolved after hydration. Inconsecutive patients, the incidence of dense renal medulla was 8.5% In conclusion, this in-cidence is aphysiological, variable, reflecting dehydration status.

PURPOSE: To evaluate the efficacy of power Doppler ultrasonography (PDUS) in depicting renal infarction inrabbits during experimental renal segmental arterial occlusion, and to compare the results with those of CTscanning. MATERIALS AND METHODS: In 28 rabbits weighing 2.5-4kg, the segmental renal artery was occluded throughthe left main renal artery by embolization with Ivalon (Nycomed, Paris, France). Power Doppler ultrasonography andspiral CT scanning were performed before and at 2, 5, 8, 15, and 24 hours, and 3 and 7 days after occlusion of thesegmental renal artery. The location of infarcted areas and collaterals, as seen on PDUS and CT scans, wasevaluated by two radiologists. RESULTS: In all cases, as seen on power Doppler ultrasonography, infaretedareas-when compared with normal parenchyma, clearly demonstrated wedge-shaped perfusion defects in the kidney. Thelocation of the lesion closely corresponded to the location seen during CT scanning. After renal arterialocclusion, transiently congested capsular arteries, which were named 'capsular sign', were seen in 63% ofrabbits in the two and five-hour groups. No significant cortical rim sign was demonstrated on power Dopplerultrasonography, though it was noted on spiral CT at 15 and 24 hours, and 3 and 7 days after renal arterialocclusion. CONCLUSION: Power Doppler ultrasonography was useful for the diagnosis of renal infarction. Congestedcapsular artery seen in the early stage of renal infarction might be a characteristic finding of this condition,as seen on power Doppler ultrasonography.

PURPOSE: The purpose of the study was to compare CT with scintigraphy in the detection of parenchymal lesionsof acute pyelonephritis in children, and to assess the diagnostic value of CT. MATERIALS AND METHODS: This studyinvolved 32 children with acute pyelonephritis ; their ages ranged from 1 month to 10 years. Renal CT , TC-99mDMSA planar and SPECT images, and medical records were retrospectively reviewed. We evaluated the number, size,shape, density, and location of pyelonephritic lesions, as seen on CT and scintigraphic images. RESULTS: In 43involved kidneys, 193 parenchymal lesions of acute pyelonephritis were identified. The results of CT were abnormalin 42 kidneys (98%), and those of scintigraphy, in 39(91%). CT showed single or multiple hypoenhancing parenchymallesions ; these were streaky(n=151), wedge-shaped (n=34), or oval (n=8), and ranged from about 3-30mm in maximumdiameter. Abscess (n=5), renal fascial thickening (n=6) and thickening of the bridging septae (n=7) wereassociated. Scintigraphic findings were diffuse or localized area of varying degrees of diminished corticalactivity, and these were more precisely identified on SPECT than on planar images. For the detection of 55 of 193pyelonephritic lesions, CT was more sensitive than scintigraphy ; 29 of the 55 lesions were less than 5 mm indiameter. CONCLUSION: For the detection of pyelonephritic lesions, particularly smaller ones, and for theevaluation of complications such as abscess formation, CT is more sensitive than Tc-99m DMSA scintigraphy. Weconclude that in children with subtle scintigraphic findings who are in serious clinical condition or in whomcomplications are suspected, CT is a useful tool for assessing a therapeautic plan and the prognosis of acutepyelonephritis.

PURPOSE: The purpose of this study was to evaluate the utility of renal CT scanning and to histologicallycorrelate renal damage induced by renal arterial infusion of 0.2 ml/kg of doxorubicin-lipiodol emulsion. MATERIALS AND METHODS: Renal CT scans of 20 rabbit kidneys were obtained 15 days after transcatheter arterialchemoembolization and were classified into four grades, as follows : Grade 0 - no fleck, Grade 1 - one to threenodular flecks ; Grade 2 - four or more nodular flecks, or one semilunar fleck ; and Grade 3 - two or moresemilunar flecks. The percentage of histological section occupied by lesion was determined using squared paper,and compared with the grades determined on the basis of CT. RESULTS: The histologic findings were interstitialinflammatory cell infiltration, intratubular lipiodol droplets, dystrophic calcification, and cellular necrosis.The mean sizes of grade 0, 1, 2 and 3 histological lesions were 2.2%(n=5), 4.5%(n=4), 21.9%(n=7), and 24%(n=4),respectively. Grades 0 and 1 accounted for nine cases(3.2%), while grades 2 and 3 accounted for 11(22.6%) ; thisdifference was statistically significant(p<0.01). CONCLUSION: CT findings showing nodular or semilunar flecks 15days after infusion into the renal artery of doxorubicin-lipiodol emulsion correlate with the size of the damagedkidney, as seen on histological specimens.

Xanthogranulomatous pyelonephritis is an atypical severe renal parenchymal infection, characterized macroscopically by a yellow lobulated mass, and microscopically by massive inflammatory cells and foamyhystiocytes. Preoperatively it can be confused with hypernephroma, pyonephrosis with stone or other renal inflammatory diseases, We present a case of xanthogranulomatous pyelonephritis associated with xanthogranulomatous epididymoorchitis. To our knowledge this is the first report of xanthogranulomatous pyelonephritis associated with xanthogranulomatous epididymo-orchitis.
