INTRODUCTION AND AIM: Posterior urethral valves (PUV) are often associated with bladder dysfunction. Our primary aim was to investigate bladder status following primary valves resection to gather evidence of function and to guide early clinical management. PATIENTS AND METHODS: Between July 2015-2020, we prospectively evaluated bladder function of PUV infants. Primary outcomes measured were number of voids, voided volume (VV), post-void residual (PVR) and bladder capacity (BC)...

INTRODUCTION: The aim was to compare the efficacy of polyacrylate polyalcohol copolymer (PPC) injections and dextranomer/hyaluronic acid (Dx/Ha) injections for the endoscopic treatment of vesicoureteral reflux in children. MATERIAL: This retrospective cohort study included 189 young patients who had endoscopic treatment for vesicoureteral reflux from January 2012 to December 2019 in our center. Among them, 101 had PCC injections and 88 had Dx/Ha injections. Indications for treatment were vesicoureteral reflux with breakthrough urinary tract infection or vesicoureteral reflux with renal scarring on dimercaptosuccinic acid (DMSA) renal scan...

INTRODUCTION: Primary Upper tract urothelial carcinoma (UTUC) is a rare subtype of urothelial carcinoma and has an unknown incidence and prevalence in Yemen. Radical nephroureterectomy (RNU) with bladder cuff removal is the standard treatment for UTUC. CASE PRESENTATION: We present a 67-year-old male patient who developed grade II vesicoureteral reflux (VUR) on the left side of the urinary tract after undergoing right-sided RNU for non-invasive UTUC. Follow-up examinations at one-, three-, and six-month post-surgery revealed no evidence of kidney diseases...

AIMS: Hepatocyte nuclear factor 1β ( HNF1B ) mutations are the most common monogenic cause of congenital anomalies of the kidney and urinary tract (CAKUT). We aimed to investigate clinical and genetic characteristics of patients with HNF1B nephropathy to expand its phenotypic and genetic spectrum. MATERIALS AND METHODS: This retrospective cohort study included 16 unrelated pediatric patients (6 females, 10 males) from 13 families with genetically confirmed HNF1B -related nephropathy...

INTRODUCTION: Bladder profile in boys with Posterior Urethral Valves can be very varied with a spectrum going from high pressure, unstable, hypocompliant small bladders to hypercompliant, large acontractile bladders, with some being near-normal. Our question was whether appearance, specifically of the bladder, on initial VCUG was correlated to prenatal features and whether it could predict early postnatal outcome. METHOD: We used a prospectively gathered database of boys with prenatally suspected PUV...

AIM: We aimed to study the presence of lower urinary tract dysfunction (LUTD) and those objective parameters obtained from voiding diary (VD), uroflowmetric (UF) and postvoiding residual urine (PVR) and voiding dysfunction symptom score (VDSS) as possible factors effecting the success rate on STING to correct VUR. MATERIALS AND METHODS: Children who underwent STING for the first time due to low-moderate (I-III) grade of VUR were evaluated retrospectively. All children diagnosed with VUR were routinely evaluated for LUTD with VD, UF, PVR and VDSS...

OBJECTIVES: To compare characteristics and outcomes of vesicoureteral reflux (VUR) detected solely on isotopic cystography (IC) ("occult" VUR) with voiding cystourethrography (VCUG)-detected VUR. MATERIALS AND METHODS: Between 2015 and 2020, we retrospectively enrolled all male children first undergoing VCUG and, if negative, IC in the same session. Kidney injury (KI) was defined by abnormal estimated glomerular filtration rate and/or blood pressure and/or proteinuria...

AIM: To determine (i) prevalence and the risk factors for acute kidney injury (AKI) in children hospitalised for febrile urinary tract infection (fUTI) and (ii) role of AKI as indicator of an underlying VUR. AKI, in fact, is favoured by a reduced nephron mass, often associated to VUR. METHODS: This retrospective Italian multicentre study enrolled children aged 18 years or younger (median age = 0.5 years) discharged with a primary diagnosis of fUTI...

Distal renal tubular acidosis (dRTA) is a clinical picture of hyperchloremic hypokalemic metabolic acidosis with a normal anion gap. It can be caused by a variety of conditions including obstructive uropathy such as vesicoureteral reflux (VUR). We report a rare case of dRTA secondary to VUR in a 4-year-old girl with a history of meningomyelocele, neurogenic bladder and recurrent urinary tract infections. She was admitted to the hospital with complaints of polydipsia, polyuria, and inability to gain weight for the last 1 year...

PURPOSE: To evaluate the effectiveness of preoperative ultrasound (US) measurements in predicting pediatric vesicoureteral reflux (VUR) treatment outcomes. METHODS: This prospective study enrolled 35 patients (53 renal units) aged 1-16 years who underwent subureteric injection therapy for primary VUR between July 2020 and June 2022. Preoperative ultrasound examinations measured the bladder wall thickness at the ureteral orifice, ureteral submucosal tunnel length, distal ureteral diameter, patient demographics, VUR grade, presenting complaints, bladder-bowel dysfunction, and renal scarring, and the impact of these variables on treatment success was analyzed...

BACKGROUND: Bladder exstrophy (BE) poses challenges both during the surgical repair and throughout follow-up. In 2013, a multi-institutional BE consortium was initiated, which included utilization of unified surgical principles for the complete primary repair of exstrophy (CPRE), real time coaching, ongoing video capture and review of video footage, prospective data collection, and routine patient data analysis, with the goal of optimizing the surgical procedure to minimize devastating complications such as glans ischemia and bladder dehiscence while maximizing the rate of volitional voiding with continence and long term protection of the upper tracts...

OBJECTIVE: This study aimed to introduce and evaluate the feasibility and outcomes of a novel surgical technique, robot-assisted Foley tie ureteric tapering (RAFUT) and reimplantation, specifically designed for intravesical ureteral tapering during pediatric robotic-assisted ureteric reimplantation. MATERIALS AND METHODS: A retrospective analysis was conducted on pediatric patients diagnosed with primary vesicoureteric reflux (VUR), who underwent RAFUT between January 2019 and July 2021...

OBJECTIVE: To assess the role of voiding cystourethrography (VCUG) in patients with duplex system ureterocele (DSU) undergoing endoscopic decompression (ED). MATERIALS AND METHODS: This is a retrospective study of 75 consecutive patients with DSU undergoing ED [median (range) age, 6 (1-148) months]. Patients were divided into 3 groups, 33 with a VCUG showing vesicoureteral reflux (VUR) before ED (VUR-group), 22 with a VCUG negative for VUR (No-VUR-group), and 20 who did not undergo a VCUG (No-VCUG-group)...

METHODS: The retrospective study included 32 patients under 14 years diagnosed with primary vesicoureteral reflux (VUR). All these patients underwent robotic-assisted Lich-Gregoir ureteral reimplantation in our department from December 2020 to August 2022. These patients were divided into the following groups according to the different ways of trocar placement: 13 patients in group single-port plus one (SR) and 19 patients in group multiple-port (MR)...

UNLABELLED: In patients with complete double renal system with the involvement of only one system, there are several surgical alternatives for its resolution. Uretero-ureteral anastomosis has been presented as a good alternative, even in cases with atrophy of the affected system. OBJECTIVE: To report our experience in patients with complete double renal system with only one system affected, with the surgical technique of uretero-ureteral anastomosis. PATIENTS AND METHOD: Retrospective study of patients with double renal system with involvement of one of the systems, treated with uretero-ureteral anastomosis technique between January 2015 and May 2022...

PURPOSE: Some children with hypertension (HTN) have unilateral poorly functional kidney (PFK). This provides an opportunity for the clinician to cure the HTN by removal of the PFK, thereby avoiding the problems of long-term medication. However, there is sparse data in children regarding the effect of PFK nephrectomy on curing HTN. In this review, we analysed the etiology of PFK causing HTN and the effectiveness of nephrectomy in curing HTN in children. METHODS: We searched the databases to identify papers between January 2000 to December 2020 pertaining to children with PFK and HTN who underwent nephrectomy...

OBJECTIVE: This study aimed to identify the determinants affecting the time required for blood pressure (BP) restoration after autonomic dysreflexia (AD) and to propose a new method for BP measurement in individuals with cervical spinal cord injury (SCI) who experience AD. METHODS: In a prospective, single-center observational study, participants' bladders were filled with body-temperature saline until reaching cystometric capacity, as confirmed by previous urodynamic studies...

BACKGROUND: Maximum voided volumes (MVV) and maximum bladder capacities (MBC) are important parameters in the evaluation of lower urinary tract functions in children. However, consistency of MVV and MBC measurements between voiding diary (VD), uroflowmetry (UF) and cystometrography (CMG) in children with non-neurogenic lower urinary tract dysfunction (LUTD) has not been addressed specifically. OBJECTIVE: We aimed to compare the MVV in VD and UF and MBC in CMG in children with non-neurogenic LUT dysfunction and investigate for possible factors for discrepancies...

OBJECTIVE: To assess the clinical efficacy of laparoscopic Lich-Gregoir (LLG) and transvesicoscopic Cohen reimplantation (TCR) in the treatment of vesicoureteral junction obstruction (VUJO) and vesicoureteral reflux (VUR). METHODS: This study retrospectively analyzed the clinical data of 66 pediatric patients with VUJO and VUR. They were classified into two groups, undergoing either the laparoscopic Lich-Gregoir operation (LLGO) (n = 35) or transvesicoscopic Cohen reimplantation operation (TCRO) (n = 31)...
