stenosis pyeloureteral

Sandra Mühlstädt, Jennifer Kranz, Joachim A Steffens, Paolo Fornara
Ureteropelvic stenosis, also known as ureteropelvic junction obstruction, is an obstruction in the region of the pyeloureteral junction resulting in a urinary discharge disorder of the renal pelvis, which requires treatment.Since the first description of pyeloplasty by Trendelenburg in 1886 and the successful establishment of open pyeloplasty by Anderson and Hynes in 1949, the treatment strategies for ureteropelvic junction obstruction have developed considerably, especially in the last two decades. Although open pyeloplasty is still considered to be the gold standard, this concept is supplemented by modern minimally-invasive techniques today...

Renal colic (RC) represents nearly 2% of emergency department admissions. RC is defined by the occurrence of back pain which may radiate towards the abdomen and external genitals. In adults, the obstruction is caused by a urinary stone in 80% of cases. The 20 % of non-stone related RCs are due either to an intrinsic obstruction (pyeloureteral junction stenosis, ureteral tumor, ...) or an extrinsic compression (pelvic tumor, lymphadenopathy ...). In over 90% of cases, an RC does not require hospitalization and is treated with medication...

OBJECTIVE: In recent years new techniques in minimally invasive treatment of congenital stenosis of ureteropelvic junction have been developed. We report the treatment of pyeloureteral stenosis in children by percutaneous endopyelotomy. METHODS: In the work up study of a child (18 months) with abdominal palpable mass, a severe left hydronephrosis with a renal pelvis diameter of 65 mm and severely thinned renal parenchyma was found. The diuretic renogram showed an obstructive pattern with impaired renal function...

PURPOSE: In spite of advances in minimally invasive endoscopic surgery, open dismembered pyeloplasty continues to be used in many pediatric centers, especially in small children. The purpose of this work is to present our experience in the performance of this technique using a minimally invasive open pyeloplasty without intrarenal stents. MATERIAL AND METHODS: A retrospective review was made of patients between July 1992 and July 2009. During this time, 348 patients underwent open dismembered pyeloplasty...

OBJECTIVE: To compare the different times into which the convention and robotic-assisted laparoscopic pyeloplasty can be divided. To compare the rate of complications between both procedures. MATERIAL AND METHODS: A retrospective study was performed of the patients diagnosed of pyeloureteral junction stenosis and treated with convention and robotic laparoscopic pyeloplasty with more than one year of follow-up. All of the interventions were recorded and visualized...

PURPOSE: To assess the role that the muscular dysplasia, epidermal growth factor (EGFR) and interstitial cells of Cajal (ICC) C-kit +, may have in the pathophysiology of pyeloureteral stenosis (EPU). MATERIALS AND METHODS: 30 samples were studied UPJ (ureteropelvic junction), with 25 UPJ obstruction and 5 controls. Performed with Masson's trichrome staining and immunohistochemical techniques for smooth muscle actin, EGFR (epidermal growth factor) and CD117 (C-kit) (Dako)...

Ureteral endoprosthesis results are presented for 22 patients (9 males and 13 females) with long strictures of the upper urinary tract (UUT). Stenosis was caused by rectal tumor in 2 patients, by cancer of the uterine cervix in 5 patients. In a female with Burneville-Pringle disease metallic prosthesis was set in the pyeloureteral segment (PUS) of the solitary right kidney. Six patients had long strictures of the abdominal part of the ureter, 4 had PUS strictures, 3--of the ureter of the transplanted kidney and 1 had stricture of ureterocalicoanastomosis after Neivert operation...

AIM: In the last years it has spread minimally invasive therapeutic for the treatment of pyeloureteral junction obstruction in children. Some of them have got poor outcomes in 4-year-old minor children. We show our experience in the retrograde dilatation with balloon of high pressure in infants. METHODS: It's a retrospective study of 16 infants treated in our hospital. The average follow-up after the intervention is 27.4 +/- 10.0 months. The diagnostic protocol included abdominal ultrasound, cystogram and diuretic renography...

UNLABELLED: Revealing the cause of renal hypertension is a major objective in medical practice. A series of investigations are required in order to elucidate the primary disease and then the treatment surgical and/or medical. The transitory hypertension of adolescent is not discussed in this paper. Measuring the blood pressure in children is often neglected and the evaluation of the hypertension is performed after the diagnosis of the renovascular disease. AIMS: The classification of renovascular hypertension in children and the statistical evaluation of its etiology in order to reveal the most frequent renovascular disease are a topical work of several authors...

Beals-Hecht syndrome or congenital contractural arachnodactyly (CCA) is a rare, autosomal dominant connective tissue disorder characterized by crumpled ears, arachnodactyly, contractures, and scoliosis. Recent reports also mention aortic root dilatation, a finding previously thought to differentiate the condition from Marfan syndrome (MFS). In many cases, the condition is caused by mutations in the fibrillin 2 gene (FBN2) with 26 mutations reported so far, all located in the middle region of the gene (exons 23-34)...

Since the introduction of mini-invasive surgery approximately thirty years ago, Laparoscopic surgery has significantly evolved both in terms of its extended field of application and of the tools used which were diversified and improved. More recently, the development of robotic-assisted laparoscopy has brought, among other improvements, three-dimensional vision, dexterity, and a comfortable working position, which have reduced the surgeon's fatigability, the difficulties related to the operations and the learning curves of standard laparoscopy...

HYPOTHESIS: The increase in the awareness of computers in the general population and the spread of Internet as a tool for communication and knowledge, allows patients to have greater understanding of their conditions. OBJECTIVE: To evaluate the use of Internet by the population from a health area and the knowledge extracted about their urological conditions. MATERIAL AND METHODS: This prospective study included all patients of age who attended a hospital urology clinic between 1st September and 31st December 2006, in a health area of 200,000 inhabitants...

BACKGROUND: To correlate the anatomical and functional information obtained using MRI in comparison to the techniques traditionally used in the study of uropathies, and to compare their physical and socioeconomic impacts. METHODS: For a period of eleven months we carried out a prospective study of 22 patients of both sexes ranging in age from 1 to 180 months. All suffered from one or another uropathy. Fifty-five percent of the patients were from external consultation while 45% had been diagnosed prenatally...

OBJECTIVES: To report our experience with endourologic methods in the treatment of pyeloureteral stenosis in children. MATERIALS AND METHODS: From July 2004, 7 patients from 9 months to 15 years old with pyeloureteral junction stenosis (PUJ) diagnosis underwent endourologic repair. An endourological dilatation was made under radioscopic control. The procedures consist of an initial cystoscopy with a retrograde placement of catheter (4 or 5 Fr) and the guide wire (0,014''-or 0,035'')...

BACKGROUND: Prenatal diagnosis of renal pyelectasis usually involves postnatal studies to determine whether treatment is necessary or not. OBJECTIVES: To determine the incidence of fetal pyelectasis in our environment, to review our postnatal management protocol, and to review definitive diagnoses. PATIENTS AND METHOD: We performed a retrospective review of newborns with a prenatal diagnosis of pyelectasis. The variables recorded included prenatal ultrasound examinations, gestational age, sex, anthropometric data, postnatal study (ultrasound, cystography, isotopic renogram) and indication for antibiotic prophylaxis...

Endometriosis is a biologically benign albeit aggressive pathology marked by high local recurrences. Ureteral involvement accounts for only a minority of cases (0.1-0.4%) with often non-specific symptoms at clinical presentation and difficult preoperative diagnosis. Thirteen cases of severe ureteral endometriosis (i.e. causing significant obstruction to the urinary flow) were observed and surgically treated, out of 17 ureteral units affected (three cases of bilateral involvement, one case of complete pyeloureteral duplicity)...
