INTRODUCTION: Vesicoureteral reflux (VUR) corresponds to the reflux of urine from the bladder into the upper urinary system. It can be a congenital or an acquired anomaly and although its incidence is high in children it is uncommon in the adult life. One of its presentations in the adult population is the presence of recurrent Pyelonephritis. CASE PRESENTATION: Here we report a case of an adult patient with repetitive uncomplicated pyelonephritis caused by VUR...

Numerical simulations of ureter peristalsis have been carried out in the past to understand both the flow field and ureter wall mechanics. The main objective of the current investigations is to have a better understanding of the urine transport due to the peristalsis in the ureter, thus making the information helpful for a better treatment and diagnosis of ureteral complications like urine reflux. In the current study, a numerical simulation is performed using a finite-element-based solver with a two-way fully coupled fluid structure interaction approach between the ureter wall and urine...

Two common abnormalities in ureters include primary refluxing megaureter (PRM) and primary obstructed megaureter (POM). The aim of this study was to represent the numerical simulation of the urine flow at the end of the ureter with vesicoureteral reflux (VUR) and POM during peristalsis. Methodologically, the peristalsis in the ureter wall was created using Gaussian distribution. Fluid-structure interaction (FSI) was applied to simulate urine-elastic wall interactions; and governing equations were solved using the arbitrary Lagrangian-Eulerian method...

The urinary bladder collects urine from the kidneys and stores it until the appropriate moment for voiding. The trigone and ureterovesical junctions are key to bladder function, by allowing one-way passage of urine into the bladder without obstruction. Embryological development of these structures has been studied in multiple animal models as well as humans. In this report we review the existing literature on bladder development and cellular signalling with particular focus on bladder development in humans...

INTRODUCTION: Historically, patients with unilateral high-grade vesicoureteral reflux (VUR) and contralateral low-grade or resolved VUR have been treated with bilateral intravesical ureteral reimplantation, which requires postoperative admission. If the high-grade VUR side is treated alone, then the contralateral side is at risk of developing recurrent or worsening VUR. Bilateral subureteric injection of dextronomer/hyaluronic acid (DHA) is another option that can be performed as an outpatient therapy, but a single injection is less effective for high-grade VUR...

PURPOSE: Infra-vesical obstruction is uncommon in infants and generally due to urethral valves. Congenital urethral strictures (CUS), instead, defined as a concentric narrowing of the urethral lumen, are exceedingly rare in infants. MATERIALS AND METHODS: We reviewed our experience with 7 patients treated at our institution for CUS <age of 1-year. The study is a retrospective review of 7 patients treated for CUS diagnosed <age 1-year during a 10-year period...

OBJECTIVE: To determine whether perinatal smoking exposure is associated with gastroesophageal reflux (GER)-related changes in sleep-wakefulness states in neonates. STUDY DESIGN: Thirty-one neonates, referred for the investigation of suspected GER, were recruited and underwent multichannel impedance-pH monitoring and synchronized 8- to 12-hour polysomnography. The infants' exposure to tobacco smoke was estimated by means of a urine cotinine assay. The total number, frequency (h-1 ), and mean duration (minutes) of GER-pH (reflux events detected by the pH electrode only) and GER-imp (reflux events with bolus movement detected by impedance) events were determined...

INTRODUCTION: In children who remain incontinent after reconstruction of bladder exstrophy-epispadias complex (BEEC), continent anal urinary diversion (CAD) is one option to achieve continence. Known problems after CAD are an increased stool frequency and ureterointestinal stenosis. We devised a new surgical technique of CAD that we named the "Cologne pouch procedure" (CPP) that renders the possibility of separate evacuation of urine and feces. Furthermore, we connect the bladder plate to the rectosigmoid pouch instead of performing a ureterosigmoidostomy to reduce the rate of ureterointestinal stenosis...

INTRODUCTION: The aim was to investigate the relationship between vesicoureteral reflux (VUR) and renal damage in non-febrile, febrile for the first time and recurrent urinary tract infection (UTI) patients. The secondary aim was to determine whether C-reactive protein (CRP) in febrile UTIs could be a predictor of renal scarring. POPULATION AND METHODS: This prospective study included non-febrile, febrile for the first time and recurrent pediatric UTI cases. The routine lab analyses comprised a complete blood count, urea, creatinine, fully automated urinalysis, urine culture and CRP analyses...

RATIONALE: Ketamine abuse is an emerging issue in many countries, and ketamine cystitis (KC) is a growing disease which more and more urologists may encounter with. There was no gold standard diagnostic criteria of ketamine cystits established yet, but well-accepted with the positive substance abuse history and clinical symptoms. The clinical presentation of ketamine cystitis varies and may mimic those presented in interstitial cystitis (IC), such as voiding frequency, urgency with urge incontinence, dysuria, nocturia, burning sensation during urination, post urination pain, painful hematuria, and small bladder capacity, but there are still differences that KC presented with more urgency, hematuria, pyuria and upper urinary tract involvement such as ureteral stenosis, vesico-ureteric reflux, hydronephrosis and renal function impairment...

BACKGROUND: We observed in cystoprostatectomy specimens that Bacillus Calmette-Guérin (BCG) granulomatous prostatitis tended preferentially to affect the peripheral zone (PZ) and aimed to study the matter, postulating that assessment of its distribution might contribute to understanding pathogenetic processes. METHODS: Entire prostate glands from 27 men (47-83 years; mean = 69 years), who had previously received intravesical BCG therapy for non-muscle-invasive urothelial carcinoma of the bladder, were studied as whole-mount sections to determine the anatomical distribution and histopathological characteristics of BCG prostatitis...

Congenital hydronephrosis caused by ureteral anomalies, like ureteral duplicity, megaureter, ureteral ectopy and ureterocele, must be differentiated from ureteropelvic junction obstruction (UJO) hydronephrosis and from the hydronephrosis caused by vesicoureteral reflux. These represent a differentiated branch of congenital abnormalities in children even if not so common, but this fact should not be disconsidered. Over a five years period, from 111 operated children in our Clinic, we performed 13 interventions for congenital hydronephrosis, 11 (84...

PURPOSE OF REVIEW: Ureteral stent placement is a very common urologic procedure and a necessary component of many minimally invasive surgeries including ureteroscopy. Despite its widespread use, stent placement results in bothersome urinary symptoms and pain in approximately 80% of patients. This review discusses the proposed mechanisms underlying ureteral stent-related symptoms and current approaches to symptom management and the evidence to support them. RECENT FINDINGS: Though it has been extensively studied, the exact cause of stent-related symptoms remains unknown but is likely related to irritation of the bladder by the distal curl of the stent and reflux of urine through the stent up to the renal pelvis and transmission of high pressures associated with this...

PURPOSE: Urinary tract infections are relatively common in pediatric patients. Unrecognized bacteriuria at the time of urologic surgery puts patients at increased risk for perioperative complications. Many pediatric urologists obtain preoperative or intraoperative urine cultures prior to surgery, but data are lacking regarding rates and risk factors for positive intraoperative urine cultures. We conducted a retrospective cohort study of patients undergoing pediatric urologic surgery to examine factors associated with positive intraoperative urine cultures...
