Directory of Open Access Journals Sweden. Las cicatrices renales pueden presentarse sin reflujo vesicoureteral RVU y pueden no existir en presencia de reflujo severo. Se necesitan estudios controlados para poder precisar bien su utilidad o ineficiencia. A literature review was made from which the following conclusions were drawn: Renal scars causae occur without vesico-ureteral reflux and may not be present when there is severe reflux.

Although infants are at more risk, older children are also vulnerable. Surgical repair of vesicourreteral reflux does vesicorueteral reduce incidence of recurrent urinary infection, so surgery is not a treatment of choice but probably an exceptional measure. This is the case of a child whose maternal-fetus ultrasound US at twenty weeks pregnancy not detected alterations, but at the 23, 6 weeks it showed the presence of a right pelvic kidney.

reflujo vesicoureteral leve-moderado: Topics by

At twenty two days the renal US showed a right kidney with a normal size and location as well as a moderate pelvic dilation and immediately beneath its lower pole a hydronephrosis big sac in correspondence with a crossed renal ectopia with severe hydronephrosis.

His father had right vesiculorectal reflux disappeared spontaneously. Despite the prophylaxis with Cephalexin there was a urinary infection adequately treated with Cephtriaxone. Ultrasonography and radioisotope researches demonstrated the presence of a congenital anomaly.

Slight Hydronephrosis in Newborns and Breast-fed Infants: The purpose of this study was to determine the value of slight-to moderate echo graphically detected hydronephrosis in newborns and breast-fed infants that might serve as indicator for Vesicoureteral reflux VURand to evaluate the necessity of performing micturating cystourethrougraphy MCUG in these patients.

There were reviewed MCUG of patients boys and 63 girls between the ages of 0 and 18 months with slight echo graphically detected hydronephrosis in order to evaluate the presence of primary VUR.

Patients with secondary reflux or those that presented anomalies which made impossible an exact reflux gradind were excluded. However, normal kidneys with reflux which were contralateral to hydronephrotic kidneys were included in the study. For a statistical analysis of the data, each kidney was considered separately, thereby forming a total of kidneys.

Slight hydronephrosis was diagnosed when the renal pelvis anteroposterior diameter was observed to measure between 0. Of the kidneys evaluated, showed slight hydromephrosis in the echography.

The echography was normal i. There were no significant differences in the incidence of VUR among normal or hydronephrotic kidneys. There is a poor correlation between slight hydronephrosis and presence or grade of reflux in newborns and breast-fed infants.

The latter should not, therefore, be considered an indication for MCUC.

Otros hallazgos de importancia fueron: The doctor provides the treatment using general anesthesia and a child can usually go home the same day. Secondary vesicoureteral reflux Doctors treat secondary VUR after finding the exact cause of the condition.

Treatment may include surgery to El reflujo faringolaringeo en la Esfera O. The management of vesicoureteral reflux is a mainstay of pediatric urology. Vesicoureteric reflux in children. Full Text Available Aim: This study aimed to identify the differences between primary and secondary vesicoureteric reflux VUR and the effect of associated bladder abnormalities on kidney function. The review included results of radiological investigations and kidney function tests.

We used Chi-square test for statistical analysis and paired t-test to compare group means for initial and last creatinine levels. Ninety-nine children were included in this study. The mean creatinine levels initial and last for both groups were normal. Children with NNB, meningomyelocele and PUV had high creatinine at presentation with no considerable worsening of their kidney functions during the last visit.

Renal scars were present in Vesicoureteral Reflux and Duplex Systems. Vesicoureteral reflux VUR is the most common anomaly associated with duplex systems.

In addition causass an uncomplicated duplex system, reflux can also be secondary in the presence of an ectopic ureterocele with duplex systems. Controversy exists in regard to the initial and most definitive management of these anomalies when they coexist.

This paper will highlight what is currently known about duplex systems and Vsicoureteral, and will attempt to provide evidence supporting the various surgical approa Contemporary Management of Vesicoureteral Reflux. Vesicoureteral reflux VUR remains the most interesting topic of pediatric urology due to the dynamic nature of recent controversial publications.

Starting from the need for a diagnosis to the necessity and effectiveness of treatment in preventing scars, VUR remains in the relfujo. Although recent strong evidence helped as fog lights vesicokreteral this blurriness, more data are required for achieving crystal clearance. This article aims to summarize and discuss the current state of the evidence regarding VUR management.

To provide a comprehensive synthesis of the main evidence in the literature on the current and contemporary management of VUR in children; to discuss conservative management with continuous antibiotic prophylaxis CAPespecially its effectiveness and safety; and to review the current evidence regarding contemporary surgical techniques.

We conducted a nonsystematic review of the literature using the recent guidelines and PubMed database regarding surveillance, CAP, endoscopic, open, laparoscopic, and robot-assisted ureteral surgical treatment. Despite the striking results of previous studies revealing the ineffectiveness of CAP, more recent studies and veeicoureteral two fresh meta-analyses revealed a positive causae for CAP in the contemporary management of VUR.

One of the most vesicorueteral findings is the redundant rising of endoscopic correction and its final settlement to real indicated cases. Patient individualization in the contemporary management of VUR seems to be the keyword.

The evidence in the literature showed a safe and effective use of laparoscopic and robot-assisted laparoscopic reimplantations. The goal of VUR treatment is to prevent the occurrence of febrile urinary tract infections and formation of scars in the renal parenchyma.

The approach should be risk adapted and individualized according acusas current knowledge. Individual risk is influenced by the presentation age, sex, history of pyelonephritis and renal damage, grade of reflux, bladder bowel.

Primary vesicoureteral reflux VUR is a common congenital rwflujo tract abnormality in children. There is considerable controversy regarding its management. Preservation of kidney function is the main goal of treatment, which necessitates identification of patients requiring early. Vesicoureteral Reflux in Kidney Transplantation. Vesicoureteral reflux VUR is frequently found after transplantation, but its impact on graft function, urine tract infection, and graft loss remains uncertain.

Therefore our objective was to evaluate the effects of VUR on the outcome of renal transplantation. We included adult renal transplant recipients of whom a 1-week posttransplant voiding cystourethrogram was available. Study end points included occurrence of bacteriuria, renal function, and graft survival. In total, There was no significant difference in renal function at 3 months vesicouteteral 1 year in patients with and without VUR.

One- and 5-year graft survival in patients with VUR was Posttransplant VUR ccausas no correlations with early bacteriuria, renal function, and graft survival. Bladder Dysfunction and Vesicoureteral Reflux. Full Text Available In this overview the influence of functional bladder disturbances and of its treatment on the resolution vesicooureteral vesicoureteral reflux VUR in children is discussed.

Historically both bladder dysfunction entities, the overactive bladder OAB and the dysfunctional voiding DV, have been described in conjunction with VUR. Treatment of the dysfunction was also considered to influence spontaneous resolution in a positive way. During the last decades, however, papers have been published which could not support acusas results. Regarding the Vesicoureheral, a vesicoureterral study with treatment of the bladder overactivity with anticholinergics, did not influence spontaneous resolution rate in children with a dysfunction including also the voiding phase, DV and DES dysfunctional elimination syndrome, most studies indicate a negative influence on the resolution rate of VUR in children, both before and after the age for bladder control, both with and without treatment.

However, a couple of uncontrolled studies indicate that there is a high short-term resolution rate after treatment with flow biofeedback. Vesicoireteral should be emphasized that the voiding phase dysfunctions DV and DES are more severe than the genuine filling phase dysfunction OAB, with an increased frequency of UTI and renal damage in the former groups. To be able to answer the question if treatment of bladder dysfunction influence the resolution rate of VUR in children, randomized controlled studies must be performed.

Extravesical detrusorrhaphy for vesicoureteral reflux in children. Vessicoureteral detrusorrhaphy is a simple and safe approach to antireflux surgery; however, its use in Taiwan has seldom been reported.

We report the outcomes of 15 patients 23 ureters with primary vesicoureteral reflux who underwent extravesical detrusorrhaphy between January and Aprilrefkujo describe the surgical technique. Overall, vesicoureteral reflux was cured in 22 of 23 ureters. Postoperative morbidity and complications were minimal.

None of the patients had obstruction or significant hematuria. The discomfort related to bladder spasms during the postoperative period was subjectively decreased compared to the conventional transvesical technique.

There was transient voiding inefficiency in three patients, as well as urinary retention in one, which resolved spontaneously after 4 weeks of Foley catheter drainage. Our experience showed that detrusorrhaphy is an effective way to correct vesicoureteral reflux with minimal morbidity and discomfort.

Proper patient selection and strict adherence to the surgical principle are important for high success rates. Vesicoureteral reflux and reflux nephropathy. Vesicoureteral reflux VUR is mainly a primary phenomenon due to incompetence of the ureterovesical junction, mostly affecting a pediatric population. In areas with IRR the kidney surface may subsequently be depressed and the papillae retracted reflux nephropathy RN.

Most commonly, VUR is discovered vesicouretedal evaluation for urinary tract infection, but it may also be present in patients with hypertension, toxemia of pregnancy, chronic renal failure and proteinuria, and it may be found in siblings of patients with VUR.

For the time being VUR is demonstrated at radiographic MCU, whereas RN is diagnosed by demonstration of focal scars and of abnormal parenchymal thickness at urography.

In children with VUR and no abnormalities of calyces or parenchymal defects standardized measurement of the parenchymal thickness at three sites may identify vesicouretral which are likely to develop focal scars. Quantitation of focal scarring should be performed in connection with a measure of the overall kidney size. The occurrence of IRR is dependent of the papillary morphology, intrapelvic pressure and urine flow. There may be an important relationship between renal ischemia and IRR in producing a ‘vicious circle of deleterious effects’ which, combined with parenchymal extravasation, may lead to RN.

Treatment of VUR includes medical and surgical management.
