Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital malformation syndrome that is characterized by a triad of uterine didelphys, blind hemivagina, and ipsilateral renal agenesis. There is a wide variety of phenotypic presentation which is recognized as a spectrum of disease rather than a separate entity. The exact incidence and pathogenesis of HWW syndrome are yet to be investigated. While this disease typically involves adolescent girls who present with abdominal pain or a pelvic mass that is secondary to hematocolpos, nowadays, a majority of potential patients with HWW are being prenatally screened for renal anomalies. Therefore, it is recommended to search for uterovaginal anomalies whenever a multicystic dysplastic kidney or the absence of a kidney is noted in a newborn female, and the role of pediatric nephrologists has become ever more important for early recognition of the disease.

지속적 신대체요법은 소아 중환자에서 전세계적으로 최근 20년 이상 사용되어져 왔고. 국내에서 역시 그 사용이 소아 중환자에서 급성 신대체요법으로 증가하고 있지만, 아직까지는 경험이 부족하고 치료지침이 없는 상태이다. 이 종설은 지속적 신대체요법의 기본 기술을 기술하는 동시에 소아와 성인의 처방의 차이, 그리고 주요 논쟁에 대해서 다루고 있다.

Excretory urography is a procedure where opacification of the kidneys, renal pelvic diverticula, ureters, and urinary bladder is a result of renal excretion of an intravenously administered iodinated contrast agent providing both anatomical and functional assessment. And ultrasonography is a non-invasive modality to evaluate the important anatomic information concerning the size, shape, and internal architecture of kidney even in the presence of impaired renal function or abdominal fluid. We describe four dogs with urological signs diagnosed with excretory urography and ultrasonography. Parients showed a variety of clinical signs including vomiting, hematuria, anorexia, abdominal pain, and abdominal distension. The hydronephrosis was diagnosed in case 1, 2, and 3 that had pelvic dilation, dilation of pelvic recesses, ureteral dilation. In case 3, proximal ureteral rupture was diagnosed with evidence of contrast media leakage was seen in proximal ureter. In case 4, the rupture of urinary bladder was diagnosed with leakage of contrast media through its ventral portion.

The nutcracker syndorme refers to compression of the left renal vein between the aorta and the superior mesentric artery which results in renal vein, left gonadal vein varices, hematuria and left sided flank pain. We report this experience of 11yr-11mon of girl has typical Nutcracker syndrome with persistent proteinuria and without typical hematuria. According to the renal biopsy for persistent proteinuria, biopsy shows pathologic findings similar to minimal change nephrotic syndrome. All symtpoms relieved without any specific treatments but she had no response to steroid treatment for persistent proteinuria. Now she was followed up through OPD base without symptom and consideration of surgical intervention.

Kidney allograft transplantation is the most effective method of renal replacement for end stage renal disease patients. Still, it is another kind of 'disease', requiring immunosuppression to keep the allograft from rejection(allograft immune reaction). Immune system of the allograft recipient recognizes the graft as a 'pathogen (foreign or danger)', and the allograft-recognizing commanderin-chief of adaptive immune system, T cell, recruits all the components of immune system for attacking the graft. Proper activation and proliferation of T cell require signals from recognizing proper epitope(processed antigen by antigen presenting cell) via T cell receptor, costimulatory stimuli, and cytokines(IL-2). Thus, most of the immunosuppressive agents suppress the process of T cell activation and proliferation.

Purpose: This study aimed to investigate clinical and radiological factors that may predict high-grade vesicoureteral reflux (VUR) in patients with febrile urinary tract infection (UTI). Methods: We retrospectively analyzed medical records of 446 patients diagnosed with febrile UTI from March 2008 to February 2017. All patients underwent renal-bladder ultrasonography (RBUS), 99mTc dimercaptosuccinic acid (DMSA) renal scan, and voiding cystourethrography (VCUG), and were divided in to 3 groups: a high-grade VUR group (n=53), a low-grade VUR group (n=28), and a group without VUR (n=365). Results: The recurrence and non-Escherichia coli infection rates in febrile UTI were significantly higher in the high-grade VUR group than in the other two groups (P<0.05). RBUS showed that hydronephrosis and ureter dilatation were more frequent in the high-grade VUR group than in the other groups (P<0.05). In the high-grade VUR group, a renal cortical defect was more likely to appear as multiple defects, and the difference in bilateral renal scan uptake between both kidneys was larger than in the other two groups (P<0.001). Conclusion: Recurrent UTI, non-E. coli UTI, abnormal findings on RBUS such as hydronephrosis and ureter dilatation, and abnormal findings in the DMSA renal scan such as multiple renal cortical defects and greater uptake difference were associated with high-grade VUR. VCUG should be selectively performed when RBUS and/or DMSA renal scan reveal significant abnormalities.

Purpose: To investigate the frequency, presentation, management, and outcome of cytomegalovirus (CMV) infection in pediatric patients who underwent renal transplantation. Methods: We performed a retrospective chart review of 70 patients under the age of 18, who underwent renal transplantation between January 1990 and November 2014. A diagnosis of CMV infection was based on serology, molecular assays, antigenemia assays, and culture. CMV infection was defined as detection of virus and CMV disease was diagnosed when clinical signs and symptoms were present. Results: The number of patients with CMV infection was 18 (25.7% of renal transplant recipients). Twelve were male (66.7%), and the $mean{\pm}standard$ deviation (SD) age at infection was $13.3{\pm}3.9$ years. Median time of infection after renal transplantation was 4 months (range 1.0-31.0 months). Pretransplantation CMV status in the infected group was as follows: donor (D)+/recipient (R)+, 11 (61.1%); D+/R-, 7 (38.9%); D-/R+, 0; and D-/R- 0. Nine patients had CMV disease with fever, leukopenia, thrombocytopenia, or organ involvement such as enteritis, hepatitis, and pneumonitis. The age of disease occurrence was $13.1{\pm}3.9$ years and the median time to disease onset after renal transplantation was 8 months (range 1.0-31.0). Immunosuppressive agents were reduced or discontinued in 14 patients (77.8%), antiviral agents were used in 11 patients (61.1%), and all patients with CMV infection were controlled. Conclusions: A quarter of the patients had CMV infection about 4 months after renal transplantation. CMV infection was successfully treated with reduction of immunosuppressants or with antiviral agents.

Since renal failure causes decrease in tumor marker excretion, use of these markers in cancer care and treatment in patients with renal insufficiency or hemodialysis is controversial. The aim of this study was to investigate differences of serum levels of tumor markers CA15-3, AFP, CA19-9 and CEA in patients with impaired renal function. A total of 100 patients referred to the Tabriz Immam Reza and Amiralmomenin hospital from June 2010 to November 2011 were selected for study. Subjects were divided to 3 groups of healthy, dialysis and renal failure but non hemodialysis cases, the last category being re-grouped based on creatinine clearance. No significant relationship between different groups in serum levels of CEA (P=0.99) and CA19-9 (P=0.29) tumor markers was found. A significant correlation was observed between serum levels of AFP (P<0.001) and CA15-3 (P<0.001) and also a tendency between creatinine clearance and CEA (r=0.05, P=0.625). Creatinine clearance significantly correlated with AFP (P<0.001, r=0.53) and CA15-3 (p=0.00, r=-0.412), but not CA19-9 (P=0.089, r=-0.171). According to results of this study it appears that use of tumor markers in patients with impaired renal function should be performed with special precautions.

교차성 신전위는 두 개의 신장이 정중선의 같은 편에 나란히 위치하는 선천성 신장병이다. 대개 기형은 오른쪽에 있고 융합되어 있는 경우가 융합되지 않는 경우의 8배에 달한다. 교차성 신전위는 흔한 질환은 아니지만, 영아에서 복부에 낭성 종물이 만져지고 반대편에 신장이 없는 경우에는 고려해 보아야 한다. 다낭 형성 이상을 동반한 융합된 교차성 신전위는 대부분 초음파로 진단되므로 진단을 위해 더 이상의 검사가 필요하지 않은 경우가 많다. 그러나 방사선 동위원소를 이용한 신주사로 교차성 신전위의 기능여부를 파악해야 하고, 배설성 방광요로조영술로 방광요관 역류나 신우요관이행부의 협착이 있는지 확인해야 한다. 다낭 형성 이상을 동반한 융합된 교차성 신전위에 대한 연구는 거의 없는 실정으로 저자들은 발열, 복통을 주소로 내원한 3세 남아에서 초음파를 시행하여 다낭 형성 이상을 동반한 융합된 교차성 신전위 1례를 경험하였기에 보고하는 바이다.
