Renal Cell Carcinoma is rare in the pediatric population, making up only 2%-6% of all pediatric renal tumors. Literature on pediatric Chromophobe Renal Cell Carcinoma (chRCC) is exceptionally limited. In this report, we describe the case of a 12-year-old patient with Neurofibromatosis Type 1 (NF1), incidentally found to have a kidney lesion with pathology revealing chRCC.

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. This study reports on our short-term complications and intermediate-term continence outcomes.

- Epispadias is a developmental condition affecting boys, with varying severity and surgical treatment options ranging from simple repair to complex reconstructions of the bladder and urethra.
- This study evaluated the outcomes of 36 boys with epispadias from three institutions, focusing on their continence status and the type of surgical procedures they received over a median follow-up period of 11.3 years.
- Results showed that 92% of participants were able to void normally; however, continence rates varied based on the severity of epispadias, with complete dryness reported in 58% of those able to void.
Objectives: To assess the prevalence of pelvic ectopic kidneys (PEK) and compare renal parameters of the PEK to the orthotopic kidney following pubic bone approximation.
Methods: In four Omphalocele-Exstrophy-Imperforate Anus-Spinal Defects Syndrome (OEIS) patients undergoing second-stage repair with known pelvic and orthotopic kidneys, changes in the renal pelvis pressure (RPP), peak systolic velocity (PSV), and resistive index (RI) were measured in the pelvic and orthotopic kidneys following pubic bone approximation. A paired t-test was performed for analysis.
Introduction: Detrusor contraction in bladder exstrophy (BE) patients following reconstruction is poorly understood as there are few published studies assessing urodynamic findings in this population. Understanding the ability of the detrusor to contract in BE patients early after closure may be able to inform the longer-term management and potential for the development of future continence in this population.
Objective: We sought to evaluate early detrusor contraction using urodynamic studies (UDS) in children who had previously undergone complete primary repair of bladder exstrophy (CPRE).
