Experiences and barriers with home bladder manometry in the pediatric neurogenic bladder population: A qualitative study.

Background: Patients with neurogenic bladder are at risk of developing renal deterioration secondary to increased intravesical pressures. To date, urodynamics is the gold standard test to properly assess bladder dynamics. Home bladder manometry is a low-cost and simple method to evaluate bladder pressures and volumes during clean intermittent catheterization (CIC).

The conundrum of high-grade hydronephrosis with non-obstructive drainage on diuretic renography.

Background: Patients with high grade hydronephrosis (HN) and non-obstructive drainage on mercaptoacetyltriglycine (MAG-3) diuretic renography (renal scans) can pose a dilemma for clinicians. Some patients may progress and require pyeloplasty; however, more clarity is needed on outcomes among these patients.

Objective: Our primary objective was to predict which patients with high-grade HN and non-obstructive renal scan, (defined as T ½ time <20 min) would experience resolution of HN.

The double-face onlay-tube-onlay transverse preputial flap: An advantageous alternative to the two-stage hypospadias repair?

Objective: To compare the surgical outcomes and complications of boys who underwent double-face onlay-tube-onlay transverse preputial island flap (DFOTO) one-stage repair vs. two-stage repair for proximal hypospadias.

Study Design: Males with proximal hypospadias who underwent DFOTO or two-stage repair at a single institution from 2008 to 2021 were identified.

Recurrent ventral curvature after corporoplasty with tunica vaginalis flap.

Introduction And Objective: Optimal means to correct ventral curvature (VC) is debated. Our preferred technique for curvature greater than 45° is corporoplasty using tunica vaginalis flap (TVF). We describe our complications with TVF for ventral lengthening.

Timely orchiopexy by 18 months of age: Are we meeting the standards defined by the 2014 AUA guidelines?

Background: Cryptorchidism is one of the most common reasons for pediatric urology referral and one of the few pediatric urologic conditions in which there are established AUA guidelines that recommend orchiopexy be performed before 18 months of age. While access to timely orchiopexy has been studied previously, there is no current study with data from a national clinical database evaluating timely orchiopexy after the AUA guidelines were published. Additionally, prior studies on delayed orchiopexy may have included patients with an ascended testis, which is a distinct population from those with true undescended testicles.

Epithelioid Hemangioma of the Glans Penis in an Adolescent Male: A Case Report.

Epithelioid hemangioma is a rare vascular lesion consisting of capillaries and inflammatory infiltrate containing lymphocytes, and mast cells. The presentation of penile epithelioid hemangioma has been previously described in the adult literature; however, few cases have been reported in the pediatric population. Herein we present a case of penile epithelioid hemangioma in a 15-year-old patient with regrowth following surgical resection, requiring more extensive surgical excision with urethral reconstruction.

Single-Layer Acellular Porcine Bladder Matrix as Graft in Corporoplasty for Ventral Curvature in Pediatric Proximal Hypospadias Repair: An Initial Experience.

Background: Single-layer ACell Cytal matrix (ACell Inc, Columbia, MD) is a commercially available, acellular scaffold derived from porcine bladder epithelial basement membrane and tunica propria. We describe our initial experience using Cytal as corporal graft in pediatric patients who underwent correction of ventral curvature in proximal hypospadias repair.

Methods: A retrospective review of a single-institution, 4 surgeon hypospadias database was performed between January 2020 and December 2021.

Home bladder pressure measurements correlate with urodynamic storage pressures and high-grade hydronephrosis in children with spina bifida.

Background: Patients with spina bifida are at risk for developing bladder and renal deterioration secondary to increased bladder storage pressures.

Objectives: To determine the association of home bladder volume and pressure measurements (home manometry) to: 1) detrusor storage pressures on urodynamics (UDS); and 2) the presence of Society of Fetal Urology (SFU) grades 3-4 hydronephrosis on renal bladder ultrasound in patients with spina bifida.

Methods: Data were prospectively collected on patients with spina bifida and neurogenic bladder requiring clean intermittent catheterization.

Continuous antibiotic prophylaxis in isolated prenatal hydronephrosis.

Background: Prenatal hydronephrosis (PNH) is one of the most common congenital anomalies and can increase the risk of developing a urinary tract infection (UTI) in the first two years of life. Continuous antibiotic prophylaxis (CAP) has been recommended empirically to prevent UTI in children with PNH, but its use has been controversial.

Objective: We describe the incidence of UTI in children with isolated PNH of the renal pelvis without ureteral dilation.

Prospective evaluation of radiation dose with conventional fluoroscopic voiding cystourethrogram in pediatric patients.

Introduction: Skin entrance doses for voiding cystourethrogram (VCUG) have not been well characterized in the literature. Radiation exposure is measured as either dose area product (DAP) or air kerma, which estimates the effective dose, but does not accurately reflect absorbed dose at skin level.

Objective: The objective of this study was to measure the skin entrance dose during fluoroscopic VCUG study in pediatric patients using single point dosimeters.

Risk of urinary tract infection in patients with hydroureter: An analysis from the Society of Fetal Urology Prenatal Hydronephrosis Registry.

Background: Prenatal hydronephrosis is one of the most common anomalies detected on prenatal ultrasonography. Patients with prenatal hydronephrosis and ureteral dilation are at increased risk of urinary tract infection (UTI) and continuous antibiotic prophylaxis (CAP) is recommended. However, current guidelines do not define the minimum ureteral diameter that would be considered a dilated ureter in these patients.

Crowd-Sourced Assessment of Surgical Skills of Urology Resident Applicants: Four-Year Experience.

Objective: To determine a) if surgical skills among urology resident applicants could be reliably assessed via crowdsourcing and b) to what extent surgical skills testing impacts resident selection.

Design: Interviewees completed the following surgical skills tasks during their interview day: open knot tying (OKT), laparoscopic peg transfer (LPT), and robotic suturing (RS). Urology faculty and crowd-workers evaluated each applicant's video-recorded performance using validated scoring and were assessed for agreement using Cronbach's alpha.

A multicenter study of acute testicular torsion in the time of COVID-19.

Background: Testicular torsion is a surgical emergency, and time to detorsion is imperative for testicular salvage. During the COVID-19 pandemic, patients may delay emergency care due to stay-at-home orders and concern of COVID-19 exposure.

Objective: To assess whether emergency presentation for testicular torsion was delayed during the COVID-19 pandemic, and whether the rate of orchiectomy increased compared to a retrospective period.

Retractable foreskin reduces urinary tract infections in infant boys with vesicoureteral reflux.

Background: Uncircumcised males are at higher risk of urinary tract infection (UTI) in the first year of life and circumcision is recommended as an option for males with vesicoureteral reflux (VUR). Uncircumcised males treated successfully with topical corticosteroid cream have decreased risk of UTI but the role of preputial management has not been explored previously in males with VUR.

Objective: We hypothesized that among uncircumcised boys with VUR, those with retractable foreskin would be at reduced risk of UTI compared to those with non-retractable foreskin.

Crizotinib-associated Renal Cyst Formation in a Pediatric Patient With ALK+ Epithelioid Inflammatory Myofibroblastic Sarcoma.

Background: Crizotinib is a first-generation tyrosine kinase inhibitor used for anaplastic lymphoma kinase (ALK) positive cancers. Simple and complex renal cyst formation is a rare complication of crizotinib use that has been reported previously in the adult population.

Case: We report a case of a right renal mass in a 17-year-old with ALK-positive epithelioid inflammatory myofibroblastic sarcoma treated with Crizotinib.

Ipsilateral ureteroureterostomy for ureteral duplication anomalies: predictors of adverse outcomes.

Introduction And Objective: Ipsilateral ureteroureterostomy (UU) has gained popularity for treating ureteral duplication (UD) associated with obstruction or vesicoureteral reflux (VUR). Several studies have demonstrated its high success rate and low morbidity. This study aimed to identify the predictors of adverse outcomes associated with UU.

Randomized open-label trial comparing topical prescription triamcinolone to over-the-counter hydrocortisone for the treatment of phimosis.

Background: Phimosis is a common condition affecting most infant boys and generally resolves over time without symptoms. Severe cases of phimosis can lead to balanoposthitis, urinary tract infections, and urinary retention. Medical treatment for symptomatic phimosis includes topical corticosteroids with manual foreskin retraction.

Testicular Volume Changes in Laparoscopic Staged Fowler-Stephens Orchiopexy: Studying the Impact of Testicular Vessel Division.

Objective: To study the effect of testicular vessel division on testicular volume during laparoscopic staged Fowler Stephens orchiopexy (LSFSO).

Methods: Testicular dimensions were prospectively measured intraoperatively at both first (S1) and second stages (S2) of LSFSO, and with scrotal ultrasound 3-12 months postoperatively. Testicular volumes were compared to reference ranges.

Urologic Phenotype and Patterns of Care in Patients With Megacystis Microcolon Intestinal Hypoperistalsis Syndrome Presenting to a Major Pediatric Transplantation Center.

Objective: To describe the phenotype, referral pattern, and trends of urologic management for children with megacystis microcolon intestinal hypoperistalsis syndrome.

Materials And Methods: We performed a retrospective review of all patients with megacystis microcolon intestinal hypoperistalsis syndrome treated at a large tertiary children's medical center over a 14-year period. Our primary outcomes included the rate of urology referral, urodynamic characteristics of bladder function, and the proportion of patients managed with clean intermittent catheterization.
