Renomedullary interstitial cell tumors are often incidentally identified either upon autopsy or kidney resection for other reasons. However, rare renomedullary interstitial cell tumor cases resulting in a clinical symptomatic mass have been reported. We present a case of renomedullary interstitial cell tumor that was manifested as an incidentally detected renal mass and mimicked renal cell carcinoma on the imaging features.

Purpose : We analysed $^{99m}Tc-MAG_3$ renal scans to evaluate renal function of transplanted kidney and to detect various renal transplant complications, measuring the ratio of renal radioactivity at three minutes to that at 20 minutes(elimination index). Material and Methods : The fifty seven renal transplantation recipients were studied. There were 50 normal functioning transplanted kidneys as group I and 7 abnormal function-ing transplanted kidney, including 5 cases of acute renal rejection, 2 cases of acute tubular necrosis as group IIl. The protocol consisted of: (1) $^{99m}Tc-MAG_3$ 740MBq injection intravenously : (2) sequential imaging for 2min(60two-second images) followed by 30min(30 sixty-second images) : (3) drawing of region of interest(ROI) on renal imaging; (4) time-activity corves were generated from renal ROI after background subtraction, and time of maximum activity($T_{max}$) and half time of maximal peak radioactivity($T_{1/2}$) were produced in the renogram curve. (5) EI through Bischof-Delaloye method as determined on the renogram curve. Results : Normal group( I ) shows mean EI of 2.21(95.0% Confidence limit of 2.01-2.87), $T_{max}$ of 154 sec, $T_{1/2}$ of 1,139 sec. Abnormal group(II) shows mean EI of 0.74, $T_{max}$ of 1,466 sec, $T_{1/2}$ of 19,224 sec. The EI, $T_{max}$, $T_{1/2}$, BUN and serum creatinine values are significantly different between normal group(I) and abnormal group(II) (p<0.0001). Conclusion : By measuring EI with $^{99m}Tc-MAG_3$, renal function of transplanted kidney could be easily evaluated and various complications could be detected early.

Multilocular cystic nephroma is a rare disease, noninherited benign renal neoplasm occurring in both children and adults. It is necessary to make a differential diagnosis from all renal diseases with a cystic component, such as Wilms tumor, harmatoma or polycystic dysplastic kidney in childhood. There are about only 200 case reports in the world since Walter Edmunds had described it first. We report a case of multilocular cystic nephroma presented with painless abdominal mass, treated with nephrectomy and confirmed with pathology. (J. Korean Soc Pediatr Nephrol 2001 ;5 : 219-24)

The Russell-Silver syndrome (RSS) is a disease characterized by intrauterine growth retardation with preserved head circumference, facial dysmorphism and short stature. Reported renal and urinary manifestations of RSS include horseshoe kidney, renal tubular acidosis, hydronephrosis, ureteropelvic obstruction and vesicoureteral reflux. Here we report a case of end-stage renal disease associated with RSS, which, to the best of our knowledge, has not been reported yet.

A 9-year-old boy of B blood group with end-stage renal disease due to IgA nephropathy received group O kidney transplantation from his father On day 9, he developed intravascular hemolysis, and anti-B autoantibody formation was confirmed. We diagnosed as immune hemolytic anemia due to passenger lymphocyte from donor, and cyclosporine withdrawl was done. Anemia resolved spontaneously, but on day 18, graft dysfunction developed, and graft biopsy revealed acute allograft rejection. Although hemolysis due to autoantibody is very rare and often mild, and the role of hemoglobinuria on acute rejection in this case is not certain, we recommend consideration of aggressive management on severe hemolysis after minor mismatched kidney transplantation.

The distribution of renal veins of fifty Korean native goats(100 kidneys) was observed. The results obtained were as follows: 1. In all goats a single renal vein, both on the left and right sides, emerged from the hilus of the kidney and then entered the posterior vena cava. 2. The ventral and dorsal surfaces of the kidney were drained through several segmental veins. These segmental veins were grouped into 2-3 Rami to formed the main trunk of the renal vein. The segmental veins drained into Rami dorsalis and ventralis, in 56 percentage of the left and 64 percentage of the right kidney and the remainder goats drained into Rami cranialis and caudalis; Rami cranialis, medius and caudalis; Rami ventralis, medius and dorsalis. 3. The ventral and dorsal surfaces of the kidney were divided into 2-4 venous segments. Among them three segments were mostly frequent (55 percentage). 4. A common segment vein was drained both dorsal and ventral surfaces at the cranial, caudal pole, and both poles. The frequency of the common segment was 32 percentage at the cranial, 18 percentage at the caudal pole, and 14 percentage at the both poles. 5. A polar renal vein was not observed. 6. The renal veins and the renal arteries did not match in arrangement and in course.

Purpose: This study was conducted to evaluate the effects of nurse-led interventions on quality of life, medication adherence, anxiety, and depression in kidney transplant recipients. Methods: A systematic literature review was conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Two researchers independently selected the final literature, and the quality assessment was performed using Cochrane's Risk of Bias tool. Additionally, a meta-analysis was conducted using the statistical software RevMan 5.4 to estimate effect sizes. Results: Among the reviewed 2,264 papers, 8 final papers, including 6 from the literature search and 2 from manual searches, were included in the analysis. The total number of participants included in the analysis was 477. Nurse-led interventions were found to be effective in improving quality of life (d=1.05) and reducing anxiety (d=-0.98) and depression (d=-1.25). Due to the heterogeneity of the measurement tools, the effect size for medication adherence could not be calculated. Despite this, nurse-led interventions were shown to improve medication adherence. In the cases of anxiety and depression, longer intervention periods showed a more significant reduction trend. Conclusion: The results of this study suggest that nurse-led interventions positively impact quality of life, medication adherence, anxiety, and depression in kidney transplant recipients. Therefore, it is important to recognize the crucial role of nurses and explore ways to provide continuous nursing interventions for kidney transplant recipients.

This study was conducted to provide the microanatomical information of the heart-kidney complex of Tegillarca granosa. The heart-kidney complex was located in the pericardial cavity between the dosal visceral mass and posterior adductor muscle. The heart composed of two atrium and one ventricle. The kidney composed of a pair of left and right. The atrium and ventricle of the heart were composed of the epicardium, myocardium and endocardium. The epicardium of simple epithelial layer composed of cuboidal epithelial cells that had a strong basophilic nucleus located in the center. The myocardium composed of muscle fiber bundles. The myocardium in ventricle was denser than in the atrium. The endocardium of simple epithelial layer composed of squamous epithelial cell that had a strong basophilic nucleus was located in the center. The endocardium thickness of the atrium was $6.04({\pm}2.26){\mu}m$, endocardium thickness of the atrium was $7.36({\pm}3.21){\mu}m$, and appeared to be thicker in the ventricle. The kidney composed of numerous renal tubules. The renal tubule of simple epithelial layer composed of columnar epithelial cell with nucleus located in the basal zone and a number of cytoplasmic granules. The developed striated border was the inner epidermis.
