Vesicoureteric reflux in the adult

Should renal color Doppler ultrasonography be a routine test in newly diagnosed hypertensive patient?

: European Society of Hypertension/European Society of Cardiology guidelines recommend calculation of estimated glomerular filtration rate and evaluation of urinary albumin excretion rate as routine tests in the initial evaluation and during the follow-up of all hypertensive patients. However, from a clinical point of view, renal ultrasound - a noninvasive, readily available and cheap imaging modality - could contribute to the better evaluation of a hypertensive patient by identifying common causes of secondary hypertension (HTN) originating from the kidney and more recently by detecting renal injury in severe or long-standing essential HTN by measuring renal resistive indexes. The purpose of this review is to summarize the actual evidence which could support a larger use of renal ultrasound in the work-up of patients with newly diagnosed HTN.

Vesicoureteral reflux in a nonfunctioning kidney detected by 99mTc-DTPA study

Vesicoureteral reflux (VUR) is a well-recognized condition in the pediatric population, but is less well described in the adult population, and its prevalence decreases with increasing age. We describe the case of a 53-year-old male with nonfunctional kidney in which accumulation of radioactivity was observed in the ureter and renal pelvis owing to VUR, which was detected by technetium-99m diethylenetriamine pentaacetic acid dynamic renal scintigraphy.

Vesicoureteral Reflux, a Scarred kidney, and Minimal Proteinuria: An Unusual Cause of Adult Secondary Hypertension

Hypertension affects about 65 million individuals in the United States. In adult patients, primary aldosteronism and renovascular causes are described as most prevalent. Vesicoureteral reflux as a cause of hypertension, while commonly described in pediatric populations, is less prevalent in the adult population especially in the absence of proteinuria. We present the case of a 31-year-old female presenting with early onset hypertension. Workup for renovascular hypertension was unrevealing. She was found to have right-sided vesicoureteral reflux with a unilateral scarred kidney. Patient underwent a nephrectomy with marked improvement in blood pressure control.

Recurrent urinary tract infections in kidney transplant recipients

Urinary tract infections (UTIs) are the most common infectious complication after kidney transplantation (KT). Recurrent UTIs after KT can contribute to increased morbidity and may also be associated with graft loss and mortality. Though several risk factors like female gender, diabetes mellitus, presence of ureteric stents, native kidney disease with urological malformations and re-transplantation have been associated with recurrent UTIs after KT, vesicoureteric reflux appears to be a unique risk factor in this patient population. The emergence of drug-resistant pathogens as causative agents for post-transplant recurrent UTIs poses a significant therapeutic challenge. The use of pathogen-specific antibiotic therapy guided by culture and sensitivity data is warranted. The optimal duration of antimicrobial therapy for recurrent UTIs in renal transplant recipients remains uncertain.
