Community-acquired febrile urinary tract infection caused by extended-spectrum beta-lactamase-producing bacteria in hospitalised infants.

2015

Abstract Introduction Extended-spectrum beta-lactamase (ESBL) producing bacteria are infrequent pathogens of urinary tract infections in children. The objective of our study was to investigate the presence, clinically associated characteristics and risk factors for acquisition of urinary tract infection/acute pyelonephritis (UTI/APN) in hospitalised children Methods A case-control study in a second level community hospital in Spain, in which 537 episodes of UTI/APN were investigated in a retrospective study between November 2005 and August 2014. Cases were patients with ESBL strains. For each case, four ESBL-negative controls were selected. A questionnaire with the variables of interest was…

Long-Term Followup Of 158 Young Adults Surgically Treated For Vesicoureteral Reflux In Childhood: The Ongoing Risk Of Urinary Tract Infections

2002

We recorded urinary tract infections in the long term after surgical reflux correction.A total of 158 of 189 patients (160 females and 29 males) who were followed in 1985, an average of 10.8 years after reflux surgery were contacted again in 1995. At that time median patient age was 26 years (range 15.7 to 38.8) and the average period of observation was 20.3 years (range 13.4 to 26).In 82% of the patients febrile and in 18% afebrile symptomatic urinary tract infections had developed preoperatively. In the first 10-year period after operation 46% of patients continued to have symptomatic urinary tract infections compared with 52% in the second 10-year interval. In the 2 periods the incidence…

Reflux nephropathy: a clinico-pathological study of 16 cases.

1991

The pathologic features of 16 nephrectomy specimens obtained from patients with a radiological diagnosis of reflux nephropathy were analyzed. Chronic pyelonephritis was diagnosed in 7 cases, renal dysplasia in 5 and segmental atrophy in 4. Clear correlations between pathologic pictures and pathogenic mechanisms involved in the development of renal lesions in kidneys with reflux are difficult to establish. These results show, however, that 'reflux nephropathy' is a broad term, which encompasses both congenital and acquired renal lesions.

Long-term follow-up results of vesico-ureteral reflux treated with subureteral collagen injection (SCIN).

2000

Endoscopic sub-ureteral injection is at the present a widely used technique for the treatment of vesico-ureteral reflux and it has a good range of efficacy, from 50% up to 90% in relation to different grades. In this paper we report our 1-7 year follow-up results of sub-ureteral collagen injection (SCIN).Between 1991 and 1997 we treated with SCIN 129 refluxing ureters in 93 children (60 females and 32 males), mean age 2.1 years (range 3 months-5 years). Fifty-five children had monolateral, but 37 had bilateral reflux. Distribution among different grades was 42 ureters (32.5%) grade 2, 63 (48.8%) grade 3, 24 (18.6%) grade 4. Children were treated with injection of highly purified bovine coll…

EAU Guidelines on Vesicoureteral Reflux in Children

2012

Context: Primary vesicoureteral reflux (VUR) is a common congenital urinary 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 intervention.Objective: To present a management approach for VUR based on early risk assessment.Evidence acquisition: A literature search was performed and the data reviewed. From selected papers, data were extracted and analyzed with a focus on risk stratification. The authors recognize that there are limited high-level data on which to base unequivocal recommendations, necessitating a revisiting of thi…

Transurethral incision of duplex system ureteroceles in neonates: does it increase the need for secondary surgery in intravesical and ectopic cases?

2004

OBJECTIVE To evaluate the relevance of ureterocele ectopia and associated reflux on the outcome of duplex system ureteroceles (DSU) after neonatal transurethral incision (TUI). PATIENTS AND METHODS The study included 41 neonates with a diagnosis of DSU; the ureterocele was ectopic in 24 (58%). Before TUI, vesico-ureteric reflux (VUR) was present in 13 lower moieties (32%) and seven contralateral ureters (17%). TUI was always performed within the first month of life. The follow-up and management were tailored for each patient from the findings at ultrasonography, voiding cysto-urethrography and renal scintigraphy. Results of intravesical and ectopic DSU were compared using Fisher's exact tes…

Treatment with phenoxybenzamine of upper urinary tract complications caused by intravesical obstruction.

1975

Five children in whom reflux and progressive hydronephrosis persisted despite multiple surgical attempts or repair are described. In all cases cystomanometry displayed a marked elevation of the bladder outlet resistance combined with high intravesical pressure values. Therapy with phenoxybenzamine, an alpha-adrenergic blocker, was successful in all cases, restoring a free urine passage of the upper urinary tract and unimpaired voiding preventing urinary diversion which has been considered in some of these children. Although there were no signs of bladder neuropathy, a hyperfunction of the sympathetic innervation as acause for bladder complications is discussed.

Sonographic biometry in obstructive uropathy of children: preoperative diagnosis and postoperative monitoring.

1985

Renal sonography was performed in 92 children with obstructive uropathy or vesicoureteral reflux preoperatively and at follow-up. Renal volume and the anteroposterior diameter of the renal pelvis proved to be the most reliable morphometric criteria for objective sonographic staging and follow-up of urinary tract obstruction. If transient obstruction occurred after uncomplicated antireflux ureterovesico-plasties (n = 41), it lasted at most 4 weeks. Kidneys with transient postoperative ureterovesical junction obstruction (n = 21) reverted to normal sonographic pattern within 4 weeks following ureteral reimplantation. In cases of ureteropelvic junction obstruction (n = 30), it took up to 6 mon…

Vesicoureteral reflux in young patients: Comparison of voiding color Doppler US with echo enhancement versus voiding cystourethrography for diagnosis…

2004

We assessed the accuracy of voiding color Doppler ultrasonography (US) with echo enhancement for diagnosis or exclusion of vesicoureteral reflux (VUR) versus voiding cystourethrography (VCUG) and evaluated patient tolerance of the echo-enhancing agent. One hundred twenty-two patients (ages range, 1 month to 17 years) with 244 ureterorenal units underwent voiding color Doppler US with echo enhancement, which was followed by VCUG on the same day. After US of the urinary tract, the bladder was filled with saline solution via catheter. Then an echo-enhancing agent was instilled, and color Doppler US was performed. Reflux was diagnosed when microbubbles appeared in the ureter or the pelvicalicea…
