Unmasking Ureteral Polyps: Insights From a Case Series.

Fibroepithelial polyps in the urinary tract are a rare cause of obstructive uropathy with fewer than 130 cases reported in the literature. In our series, we describe polyps that were missed on preoperative imaging and later found in the operating room during pyeloplasty. It is critical for urologists to be aware of polyps as a potential source of obstruction as they can increase the complexity of a reconstruction and, if missed, may result in a failed repair and persistent obstruction.

Atrial Septum Perforation Via Levoatriocardinal Vein in a Newborn With Hypoplastic Left Heart Syndrome.

Hypoplastic left heart syndrome with intact atrial septum has high perioperative mortality. An interventional septum perforation from the right atrium may be technically challenging in newborns with high risk of tamponade. However, neonates with a levoatriocardinal vein provide an alternative approach for septostomy from the left atrium side.

Clinical considerations in adults with history of posterior urethral valves.

Introduction: Management of patients with posterior urethral valves (PUV) is commonplace for many pediatric urologists, however adult providers may be far less familiar with this diagnosis, its management and long-term ramifications. As urologic management of these patients has evolved, clinical outcomes have substantially improved with many more patients now surviving into adulthood. These patients remain at increased risk of morbidity due to their condition and therefore are likely to benefit from long term follow-up with adult providers.

Does Preoperative Testosterone Administration Decrease Complications in Distal Hypospadias Repair With Urethroplasty?

Purpose: Testosterone administration prior to hypospadias repair is common practice among pediatric urologists; however, its impact on surgical outcomes remains controversial. We hypothesize that testosterone administration prior to distal hypospadias repair with urethroplasty significantly decreases postoperative complications.

Materials And Methods: We queried our hypospadias database for primary distal hypospadias repairs with urethroplasty from 2015 to 2021.

Deferring gonadectomy in patients with turner syndrome with a genetic Y component is not a safe practice.

Introduction: Patients with Turner syndrome who harbor Y chromosome material are known to be at increased risk of developing germ cell neoplasms. The optimal timing to perform gonadectomy to reduce the risk of cancer development in these patients is not well defined. We present outcomes of Turner with a Y component (TSY) patients who underwent gonadectomy at our institution.

Office Based Pediatric Urologic Procedures: A Safe and Effective Alternative to Interventions Under Anesthesia.

Objective: To report on our experience performing office-based pediatric urologic procedures. We hypothesize that office-based interventions are safe and effective for children, avoiding unnecessary risk and cost associated with general anesthesia.

Methods: We retrospectively identified patients undergoing office-based interventions from 2014 to 2019, including lysis of penile or labial adhesions, division of skin bridges, meatotomy and excision of benign lesion.

Coronary steal phenomenon following right ventricle decompression and revascularization of atretic left coronary ostium: case report.

Background: Coronary steal phenomenon and myocardial ischemia is a complication following decompression of a hypertensive right ventricle in patients with left coronary-cameral fistulae.

Case Presentation: We present a 12-year-old girl with a complex heart defect successfully operated on using a hybrid surgical-interventional approach to decompress the ventricle, embolize the fistula and reconstruct the atretic left coronary ostium.

Conclusions: A novel hybrid strategy is the best solution for coronary-cameral fistulas reliant on high ventricular pressure at high risk for coronary steal phenomenon.

Left ventricular systolic function impairment in children after balloon valvuloplasty for congenital aortic stenosis assessed by 2D speckle tracking echocardiography.

Aims: The aim of the study was to evaluate left ventricular (LV) remodeling and systolic function using two-dimensional speckle tracking echocardiographic (2D STE) imaging in children at a long-term (more than 36 months, 107.5±57.8 months) after balloon valvuloplasty for aortic stenosis (BAV).

Robustness Analysis of the Estimators for the Nonlinear System Identification.

The main objective of the system identification is to deliver maximum information about the system dynamics, while still ensuring an acceptable cost of the identification experiment. The focus of such an idea is to design an appropriate experiment so that the departure from normal working conditions during the identification task is minimized. In this paper, the adaptive filtering (AF) scheme for plant model parameter estimation is proposed.

Long-term results of percutaneous balloon aortic valvuloplasty in children with aortic stenosis: a single-center experience.

Background: Percutaneous balloon aortic valvuloplasty (BAV) is an effective method of treatment for aortic stenosis in children.

Aims: This study aimed to assess the long‑term results of BAV in various age groups in the pediatric population.

Methods: This retrospective study included 68 patients (newborns, infants, and children older than 1 year).

Quantification of risk factors in 500 patients with postoperative urinary retention.

Introduction: An Institutional Quality and Safety Initiative to reduce postoperative urinary retention (POUR) and improve patient safety indicators (PSIs) was undertaken after a nurse driven protocol for catheter removal lead to an increase in POUR. The aim of this study was to identify the number of risk factors present in patients with POUR while examining the prevalence of those risk factors individually.

Materials And Methods: A retrospective review of our institution's surgical database was performed to identify 500 consecutive cases of POUR between July 1, 2013 and July 1, 2014.

Prostate cancer in renal transplant recipients.

As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients (RTRs) being diagnosed with prostate cancer (CaP) is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardized guidelines for screening or management of CaP in these complex patients.
