An Approach To Renal Masses In Pediatrics

Di: Ava

Advances in treatment outcomes of pediatric urologic malignancies can be largely attributed to the creation of multi‐institutional collaborations and clinical trials. 4 , 5 Current studies focus on pediatric genitourinary cancers on an individual basis, assessing renal, testicular, and urothelial malignancies separately. Purpose of Review The treatment of pediatric renal tumors is nuanced and complex. This review highlights these nuances and aims to prepare the surgeon for treating these complex patients. Recent Findings Cooperative group study has improved survival for several pediatric renal tumors significantly, namely, Wilms tumor and clear cell sarcoma. There are The histopathologic features of renal neoplasms that occur in older children and adolescents are reviewed, with emphasis on radiologic-pathologic correlation.

This review article focusses on molecular characteristics, histo morphology and syndromic association of pediatric renal tumors, their immunohistochemical approach to diagnosis with recent updates in molecularly defined renal tumors.

Paediatric renal tumours and masses are another group of diseases (just like cystic renal diseases in both the adult and child) that are bewildering in their number, nomenclature and overlapping findings. Commoner lesions Wilms tumour: common i Benign renal tumors are extremely rare and were studied here. This series also includes a renal teratoma in a horseshoe kidney, probably only the second in the pediatric literature. Retrospective review of children with benign renal tumors operated Most abdominal masses originate from the retroperitoneum, with the kidney being the principal organ involved [1]. Of these, the most common renal mass in newborns is hydronephrosis. Renal malignancies are relatively uncommon in pediatrics.

Treatment In European countries the patient first receives chemotherapy, after which the kidney is resected, followed by post-operative A variety of pediatric renal masses may be differentiated from Wilms tumor on the basis of their clinical and imaging features. Wilms tumor is distinguished by vascular invasion and displacement of

As imaging becomes more widely used, the frequency of incidentally detected renal lesions increases [1], highlighting the need for methods that can reliably characterize the lesions. Differentiation between benign and malignant lesions is crucial in deciding on a therapeutic approach. Malignant renal masses are usually surgically removed or treated with other

This webpage discusses the diagnostic approach, differential diagnosis, and management strategies for small renal masses. Malignant renal tumors account for approximately 6% of pediatric malignancies, with Wilms tumor (WT) representing approximately 90% of pediatric renal tumors. This paper provides consensus-based imaging guidelines for the initial evaluation of a child with suspected WT and follow-up during and after Malignant renal tumors are rarely seen in pediatric population and constite 7% of all childhood tumors.Although many pediatric renal tumors were classified as Wilms tumor previously, pathological updates have revealed that there are several different subtypes of renal tumorsincluding mainly Wilms tumor, mesoblastic nephroma, clear cell sarcoma, renal cell

Incidental liver lesions are increasingly being discovered in the context of the increased use of ultrasound studies and the majority are benign. In children, although individually rare, the differential diagnosis is broad and therefore a systematic approach is of utmost importance to reduce the radiological and disease burden in children and their families.

INTRODUCTION This handbook provides you with the current surgical management of Renal Tumors as of 2018. It is based on current literature and accepted practice, and is managed and updated by the APSA Cancer Committee. It is designed to consolidate the most current and up to date material you need to know when treating your patient. Please note as new Children Childhood renal masses comprise a heterogeneous group of conditions that have a wide range of presentations. This review outlines an approach to the diagnostic work-up of childhood renal masses and d

The finding of a simple kidney cyst in a child can pose a diagnostic and management challenge for pediatric nephrologists, urologists, and primary care providers. The reported prevalence varies from 0.22 to 1% in large ultrasonography-based series This document discusses paediatric abdominal masses. Ultrasound is generally the initial imaging test which can differentiate cystic from solid masses and Renovascular hypertension (RVHTN) is an important contributor to secondary etiologies of hypertension in the pediatric population. A delay in diagnosis can be associated with adverse outcomes. The etiologies of renal artery stenosis (RAS) vary from anatomical, inflammatory, genetic syndromes, intra-luminal, external compression and idiopathic. It is a

Pediatric renal tumors encompass a wide spectrum of disease entities, both benign and malignant, affecting infants, children, adolescents, and young adults. Clinical presentation varies based on age, tumor differential, and extent of disease, but common presenting features include a painless palpable mass, hematuria, fever, anorexia and weight

Abdominal masses are most often found in children less than 5 years of age. In infants, most abdominal masses are retroperiotoneal, of renal origin, and nonmalignant. The most common malignant abdominal tumor in infants is neuroblastoma, followed by Wilms‘ tumor. Other abdominal tumors in this young age range include soft tissue (rhabdomyosarcoma and Pediatric renal tumors include a heterogeneous group of diagnoses that vary greatly in both required treatment and long-term outcome. This chapter will review both benign and malignant renal masses, with a particular emphasis on pediatric kidney cancers given their impact on morbidity and mortality. Renal cancers account for 7% of all pediatric malignancies. Wilms

The management of pediatric malignant renal masses and timing of surgery varies in different groups. In India, the renal tumor size is usually large at presentation. The document discusses various pediatric retroperitoneal masses. It begins by noting that abdominal masses are most common in children under 5 years old and retroperitoneal masses in neonates are often kidney-related and benign. It then characterizes the retroperitoneal space and lists common retroperitoneal organs. Several pathologies are discussed in detail, including The finding of a simple kidney cyst in a child can pose a diagnostic and management challenge for pediatric nephrologists, urologists, and primary care providers. The reported prevalence varies from 0.22 to 1% in large ultrasonography-based series of more than 10,000 children each. The true prevalence, however, may be higher or lower, as factors such

The most characteristic appearance on prenatal US is a large measuring 3.5–8 cm, unilateral, homogeneously echogenic, solid renal mass located near the hilus and involving the renal sinus. Despite being well-demarcated from the renal tissue, a well-defined capsule is not found, and the tumour blends with the normal renal parenchyma. Abdominal masses in children can present with varying symptomatology. This chapter will delineate an organized approach to imaging pediatric patients with abdominal masses of variable ages, presentations and etiologies.

In view of the continuing technologic advancements in the development and availability of diagnostic imaging modalities, it is appropriate to assess periodically the currently accepted approaches to the evaluation of renal masses in children. The roles, advantages, and disadvantages of plain film, intravenous urography, ultrasonography, radionuclide scintigraphy, Focal adrenal lesions can occur from a variety of underlying congenital and acquired causes in the pediatric population. Although some lesions are discovered incidentally in asymptomatic individuals on imaging studies obtained for other reasons, the majority of pediatric patients with focal adrenal lesions have abdominal pain and a palpable mass.

Renal tumors comprise 7% of all childhood cancers. A wide variety of renal tumors can affect the pediatric kidneys, which can be broadly classified as primary benign tumors, primary malignant tumors, and metastatic lesions. This article aims to enumerate usual benign and malignant renal tumors that can occur in childhood and emphasizes the characteristic imaging appearances Pediatric renal tumors and masses are another group of diseases (just like cystic renal diseases in both the adult and child) that are bewildering in their number, nomenclature and overlapping findings.

This document summarizes pediatric renal tumors. It discusses that in neonates, common tumors include mesoblastic nephroma and multicystic dysplastic kidney. From 6 months to 5 years, common tumors are Wilms tumor, nephroblastomatosis, medullary tumors, and multilocular cystic nephroma. After 5 years, renal cell cancer becomes more common. Wilms tumor is described In view of the continuing technologic advancements in the development and availability of diagnostic imaging modalities, it is appropriate to assess periodically the currently accepted approaches to the evaluation of renal masses in children. The roles, advantages, and disadvantages of plain film, intravenous urography, ultrasonography, radionuclide scintigraphy,

Solid lesions can be divided into ball-type and bean-type lesions. Ball-type lesions are the most common and present as expansile masses, deforming the renal contour. Renal cell carcinomas and oncocytomas are typical ball-type lesions. Bean-type lesions do not deform the renal contour and the bean-shape of the kidney is preserved. Persistent isolated microscopic hematuria is relatively common in pediatric practice, affecting around 0.25% of children. Isolated microscopic hematuria can be caused by a myriad of potentially benign or serious causes, including urologic issues; Finding an abdominal mass on a child can be alarming to both the parents and pediatrician. Abdominal masses are often incidentally discovered by a parent while bathing the child, palpated unexpectedly on routine physical examination, or detected on abdominal imaging. The causes of pediatric abdominal masses are extensive, ranging from benign to neoplastic,

Focal renal lesions in the pediatric age group encompass a spectrum of conditions including benign congenital processes, normal anatomic variants, benign and malignant neoplasms, infection, infarction, and lymphatic malformation (Table 1). Focal abdominal cystic masses are common in pediatric patients. Affected patients present with various symptoms and physical findings depending on size, location, and mass effect on the adjacent abdominal structures. The symptoms in these patients can be abdominal pain, early satiety, bowel obstruction, or fever if the underlying cause of the mass is
