Oligomeganephronia is a rare congenital form of bilateral renal hypoplasia histologically characterized by reduction in number and hypertrophy of nephrons. Clinically, this condition is presented in early infancy with vomiting, polyuria, polydipsia and dehydration. The problems are readily corrected, but slowly progressive renal failure follows accompanied by failure to thrive, short stature, and renal osteodystrophy. We experienced three cases of oligomeganephronia. Case 1. : A 3 2/12 years old female child was incidentally diagnosed as renal failure at age of 2 months when she was hospitalized due to pneumonia. She had open renal biopsy and was diagnosed as bilateral dysplastic kidney. On OPD follow-up, she progressed to end-stage renal failure (BUN/Cr 114/4.6 mg/dl) and had renal transplantation. The specimen was shrunk remarkably and light microscopy showed oligomeganephronia. Case 2. : A 14 8/12 years old female child with proteinuria was detected in an annual urine screening program for school children, she was diagnosed as renal failure (BUN/Cr 33.9/4.1 mg/dl), and had $5{\times}4{\times}3\;cm$ sized mass on abdominal CT scan. She had renal biopsy, and the specimen showed oligomeganephronia. She had hemodialysis for six months, and renal transplantation along with bilateral nephrectomy was performed. Case 3. : A 14 8/12 years old male child was diagnosed having chronic nephritis and chronic renal failure at 3 years old, progressed to end-stage renal failure (BUN/Cr 87/9.6 mg/dl) on OPD follow-up, and had a rephrectomy and renal transplantation. The biopsy specimen showed oligomeganephronic hypoplasia, secondary focal segmental glomerolosclerosis, and chronic interstitial nephritis. We report 3 cases of oligomeganephronia that progressed to end-stage renal failure and had successful renal transplantation with a brief review of related literatures.

Purpose: This study was aimed to investigate the health related quality of life and related factors of organ transplant recipients. Method: The participants were 188 people who had liver(86), kidney(81), or heart(24) transplanted. Data on the demographic characteristics, transplantation-related characteristics, symptom frequency or discomfort measured by Transplant Symptom Frequency and Symptom Distress Scale by Lough et al(l987), and health related quality of life measured by SF-36(version 2) were collected. Result: Overall health related quality of life score was 492.1 for 100scoring and, 344.9 for norm based. Physical functioning showed the highest quality of life score (77.5) and vitality showed the lowest(51.l). The kidney transplanted showed the highest quality of life (504.4) and the heart transplanted showed the lowest(426.7) Quality of life was related with occupation(p=.016) and symtom discomfort(p < .0001). Conclusion: The health related quality of life of transplated patients was lower than the norm of American. Further studies need to be done to identify the norm of Korean and to investigate the effect of releving symptom discomfort on the increasing the health related quality of life.

목적: 본 연구의 목적은 뇌사자로부터 공여받은 신장을 이식한 대상자들이 프레드니손을 생체이식 대상자들보다 더 많이 투여받는 임상상황에서 프레드리손이 근력과 일상생활활동에 영향을 주는지 규명하기 위함이다. 방법: 연구 대상은 뇌사자로터 신장을 응급으로 수여받은 32명이었으며 모두 혈액투석을 하고 있었다. 이식 수술 전날, 환자의 일반적인 정보, 근력, 일상생활활동에 대해 조사하였으며 이식수술 후 12주째 되는 날 외래에서 근력과 일상생활활동을 다시 조사하였다. 프레드니손 용량은 임상기록지를 통해 수집하였다. 연구결과: 신장이식술 후 12주의 근력은 고관절 신전근력을 제외하고는 유의하게 감소되지 않았다. 그러나 신장이식 후 12주의 일상생활활동은 수술 직전보다 유의하게 감소된 것으로 나타났다. 근력은 혈액투석을 시행한 기간에 의한 영향을 더 받았으며 일상생황활동의 저하는 3개월간 활동을 제한하는 퇴원교육의 영향이 큰 것으로 볼 수 있다. 결론: 본 연구에서 대상자의 근력과 일상생활활동은 프레드니손 투약의 영향을 받지 않았으며 오히려 혈액투석을 시행했던 기간에 따라 영향을 받은 것으로 나타났다. 따라서 혈액투석 환자들의 근력 증진을 위한 간호중재 개발이 필요하다.

Disseminated adenovirus infection can result in high mortality and morbidity in immunocompromised patients. Here, we report the case of a 10-year-old renal allograft recipient who presented with hematuria and dysuria. Adenovirus was isolated from his urine. His urinary symptoms decreased after intravenous hydration and reduction of immunosuppressants. However, 2 weeks later he presented with general weakness and laboratory tests indicated renal failure necessitating emergency hemodialysis. Adenovirus was detected in his sputum; therefore, intravenous ganciclovir and immunoglobulin therapy were initiated. Renal biopsy revealed diffuse necrotizing granulomatous tubulointerstitial nephritis compatible with renal involvement of the viral infection. Adenovirus was detected in his serum. Despite cidofovir administration for 2 weeks, adenovirus was also detected in the cerebrospinal fluid, resulting in generalized tonic-clonic seizure. The patient died 7 weeks after the onset of urinary symptoms. Adenovirus should be considered in screening tests for post-renal transplantation patients who present with hemorrhagic cystitis.

Slowing the progression of chronic kidney disease is much more important in children and adolescents with a relatively longer remaining life span. A practical way to assess the rate of progression of chronic kidney disease is to measure the change of GFR estimated by formulae. To slow the progression, hypertension and proteinuria have to be controlled strictly, and hypoplastic anemia must be treated with erythropoietin. If not contraindicated, ACE inhibitor or angiotensin receptor blocker is recommended with monitoring of the side effects. Trials to slow the progression should be commenced as soon as the chronic kidney disease is confirmed and needs to be continued until renal transplantation as long as residual renal function remains. An online system, the Korean Pediatric Chronic Kidney Disease Registry (http://pedcrf.or.kr/), provides tools that are useful in evaluation and management of the children and adolescents with chronic kidney diseases.

Parvovirus B19(PV B19) is a nonenveloped single-stranded DNA virus that causes a wide variety of diseases ranging from benign childhood infection such as slapped-cheek rash(fifth disease) to life threatening diseases such as hydrous fetalis in fetuses or aplastic anemic crises in patients with hemolytic anemia. In immunocompromised hosts including organ transplant recipients, this infection can cause chronic anemia. Recently, the reports of cases of PV B19 infection have been increasing in transplant recipients and most reported cases of PV B19 infection-associated anemia in renal transplant recipients were successfully treated with intravenous immunoglobulin infusion. We experienced two cases of aplastic anemia caused by PV B19 infection in pediatric renal transplant recipients. The patients were an 8 year-old boy and 12-year-old boy who received allograft kidneys from their mothers. Anemia developed 2 weeks after transplantation and their serum was positive for PV B19 PCR. They were treated with 400 mg/kg of intravenous immunoglobulin(IVIG) for 5 consecutive days. In one of the case, anemia was corrected promptly after the first 5-day course of IVIG therapy but in the other, anemia persisted but responded to the second course of IVIG therapy. One year later, the patients have normal hematocrit levels and stable renal function These are the first cases of PV B19 infection treated successfully with IVIG in pediatric renal transplant recipients in Korea.

Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Transplant type. Epidemic or AIDS categories is found approximately 20 % of all AIDS and has strong predilection for head and neck region. The first case of Kaposi's sarcoma observed in patients with kidney transplants was reported in 1969. Kaposi's sarcoma now accounts for 5% of all tumors associated with transplanted patients and alteration of the immunosuppression may have played a key role in these recipients. The most common site of Kaposi's sarcoma in transplanted patients are extremities but rare in head and neck area. We report a case of Kaposi's sarcoma on the hard palate in the kidney transplantation patient.

Purpose: Despite meticulous techniques, surgical complications continue to be problematic in kidney transplant recipients. Role of routine stenting to reduce complications is controversial. In this study, we compare incidence of early urological complications, lymphoceles, urinary tract infections (UTI) and graft function; with or without double-J stenting. Materials and Methods: All patients who underwent live related donor renal transplantation from February 2014 to February 2016 were included. Transplants prior to February 2015 were without routine stenting; subsequent transplants were with routine stenting. Patients with neurogenic bladder, previously operated bladder and delayed or low urinary output were excluded. Followup was for at least three months. Descriptive statistics was performed for all parameters. Chi square test and Fisher's Exact test were used for qualitative variables. For quantitative variables, Mann-Whitney test was used to test median difference and independent samples t-test for mean difference. The p-value ${\leq}0.05$ was considered significant. Results: We analysed 74 patients (34 stented and 40 non-stented). There was no difference in the incidence of urinary leak, anastomotic obstruction, lymphoceles or UTI (p>0.4 for all comparisons). However, mean estimated glomerular filtration rate at sixth day, 14th day, one month and two months were 76.1 vs. 61.5 (p=0.025), 72.1 vs. 56.6 (p=0.005), 79.4 vs. 63.1 (p=0.002) and 82.0 vs. 63.3 (p=0.001) in the stented versus non-stented groups. Conclusions: Placement of ureteral stent in renal transplant does not significantly affect the incidence of early urinary complications or UTI. However, graft function is significantly better in stented recipients, at least in the short term.

Background: Kidney injury molecule-1 (KIM-1) is known as a good ancillary marker of acute kidney injury (AKI) and its expression has also been observed in acute rejection and chronic graft dysfunction. We tested usefulness of KIM-1 as an indicator of acute and chronic renal graft injury by correlating KIM-1 expression with renal graft function and histology. Methods: A total of 133 zero-time biopsies and 42 follow-up biopsies obtained within 1 year posttransplantation were selected. Renal tubular KIM-1 staining was graded semiquantitatively from 0 to 3 and the extent of staining was expressed as the ratio of KIM-1 positive/CD10 positive proximal tubules using Image J program. Results: KIM-1 was positive in 39.8% of zero-time biopsies. KIM-1 positive cases were predominantly male and had received grafts from donors with older age, deceased donors, and poor renal function at the time of donation, compared with KIM-1 negative cases. KIM-1 expression showed correlation with delayed graft function and acute tubular necrosis. In comparison of KIM-1 expression between stable grafts (n=23) and grafts with dysfunction (n=19) at the time of repeated biopsy, the intensity/extent of KIM-1 staining and renal histology at zero-time did not differ significantly between the two groups. Histologically, KIM-1 expression was significantly increased with both acute and chronic changes of glomeruli, tubules and interstitium, peritubular capillaritis, and arteriolar hyalinosis. Conclusions: KIM-1 can be used as an ancillary marker of AKI and a nonspecific indicator of acute inflammation and tubulointerstitial fibrosis. However, KIM-1 expression at zero-time is not suitable for prediction of long-term graft dysfunction.
