Characteristics and Outcomes of Patients With Spina Bifida in Texas by Patient Age.

Introduction: Spina bifida (SB) occurs in 3.5/10,000 live births and is associated with significant long-term neurologic and urologic morbidity. We explored the characteristics and outcomes of pediatric patients with SB and the facilities that treat them in Texas.

LUMBAR Syndrome and Bladder Exstrophy: A Case Report.

LUMBAR syndrome is rare with a multitude of features that requires a high index of suspicion for timely diagnosis and appropriate management. We present on a newborn female whose untreated segmental infantile hemangioma lead to poor healing of her bladder exstrophy closure. The objective of this report is to describe bladder exstrophy as a urogenital anomaly in patients with LUMBAR syndrome and the importance of balancing management of infantile hemangioma and time to surgery.

Is urgent surgical management necessary for priapism in pediatric patients with hematologic conditions?

Introduction: Acute priapism is usually considered a medical emergency that warrants prompt urologic evaluation and treatment. Efforts have been made to determine the optimal management strategy for pediatric priapism.

Objective: The aim of this study is to assess differences in conservative, minimally-invasive, and operative management of acute priapism in the pediatric population.

Robot assisted laparoscopic partial cystectomy for inflammatory myofibroblastic tumor with simultaneous intraoperative flexible cystoscopy for tumor mapping.

Bladder masses are an infrequent occurrence rarely suspected in cases of pediatric hematuria. Inflammatory myofibroblastic tumors represent one differential diagnosis that is difficult to characterize as purely benign and should therefore be given special consideration. Although uncommon, this is an important entity to recognize for potential bladder sparing and minimally invasive surgical approaches.

Bladder management in children with transverse myelitis.

Background: Patients with transverse myelitis (TM) often present with urinary retention. While many recover their bladder function, some have persistent voiding dysfunction, and both intermediate and long-term outcomes are variable.

Objective: In patients who develop urinary retention requiring clean intermittent catheterization (CIC) at onset of TM, we sought to assess factors associated with improved voiding function and the risk of requiring persistent CIC over time.

Papers presented at the fall 2020 Pediatric Urologic Oncology Work Group of the Societies of Pediatric Urology meetingNeonatal Serum Electrolyte and Proteinuria Screening on 46,XY Ambiguous Genitalia Patients May Allow Early Diagnosis of Denys-Drash Syndrome: A Case Report.

A term infant with prenatally noted ambiguous genitalia and nonpalpable gonads presented with life-threatening hyponatremia, hypertension, acidosis, and anuric renal failure requiring peritoneal dialysis at age 3 months.Sequencing confirmed 46, XY Denys-Drash syndrome (DDS) due to heterozygous Wilms tumor-1 exon 8 mutation encoding p.His445Arg.

Renal artery angiography in pediatric trauma using a national data set.

Introduction: With limited pediatric renal trauma management literature, treatment pathways for children have been extrapolated from the adult population. A shift to non-operative management has led to higher renal preservation rates; however, characterization of endovascular intervention in the pediatric trauma population is lacking.

Objective: This study uses the National Trauma Data Bank (NTDB), to evaluate renal outcomes after use of renal artery angiography.

Managing Ureteropelvic Junction Obstruction in the Young Infant.

In the last decade, management of congenital UPJ obstruction has become progressively observational despite the lack of precise predictors of outcome. While it is clear that many children will have resolution of their hydronephrosis and healthy kidneys, it is equally clear that there are those in whom renal functional development is at risk. Surgical intervention for the young infant, under 6 months, has become relatively infrequent, yet can be necessary and poses unique challenges.

Robotic Ureteral Reimplantation.

Minimally invasive techniques have gained popularity in pediatric surgery. Among these, is the robotic approach for ureteral reimplantation in children with vesico-ureteral reflux. We describe main indications of this surgery, our surgical technique as well as trouble shooting of anatomical variants and the post-operative management.

Initial experience with extraperitoneal robotic-assisted simple prostatectomy using the da Vinci SP surgical system.

Robotic-assisted simple prostatectomy (RASP) has emerged as a safe and effective treatment option for symptomatic patients with lower urinary tract symptoms related to significant benign prostatic enlargement (BPE) above 80 g. The recent release of the da Vinci SP robotic system (Intuitive, Sunnyvale, CA, USA) continues to advance the minimally invasive nature of robotic surgical technology. We now report our institution's initial experience performing RASP using the da Vinci SP robotic system.

Optimal sampling scheme in men with abnormal multiparametric MRI undergoing MRI-TRUS fusion prostate biopsy.

Objectives: To determine the implications of different prostate sampling schemes on the diagnosis of clinically significant prostate cancer (csPCA, ISUP group 2-5) and clinically insignificant prostate cancer (ciPCA, ISUP group 1) in men with abnormal multiparametric magnetic resonance imaging (mpMRI) undergoing MRI-transrectal ulrasound fusion targeted biopsies.

Materials And Methods: This is a retrospective analysis of a cohort including all men who had a single lesion on mpMRI of the prostate performed between January 2016 and June 2017. All men underwent an MRI-transrectal ulrasound fusion biopsy and systematic (SBx) sampling of the prostate, which combined and were considered the standard of reference.

Prospective Inclusion of Apparent Diffusion Coefficients in Multiparametric Prostate MRI Structured Reports: Discrimination of Clinically Insignificant and Significant Cancers.

Objective: The purpose of this study was to assess the diagnostic performance of prospectively assigned mean apparent diffusion coefficient (ADC) values in multiparametric MRI (mpMRI) structured reports for discriminating clinically insignificant (International Society of Urological Pathology [ISUP] group 1) from clinically significant (ISUP groups 2-5) prostate cancer.

Materials And Methods: This single-center study included men with abnormal 3-T mpMRI findings (Prostate Imaging Reporting and Data System version 2 score, ≥ 3) who subsequently underwent radical prostatectomy or targeted biopsy with positive results. One of nine radiologists prospectively reported the mean ADC for each lesion during clinical interpretation.

Phenotypic severity scoring system and categorisation for prune belly syndrome: application to a pilot cohort of 50 living patients.

Objective: To design a novel system of scoring prune belly syndrome (PBS) phenotypic severity at any presenting age and apply it to a large pilot cohort.

Patients And Methods: From 2000 to 2017, patients with PBS were recruited to our prospective PBS study and medical records were cross-sectionally analysed, generating individualised RUBACE scores. We designed the pragmatic RUBACE-scoring system based on six sub-scores (R: renal, U: ureter, B: bladder/outlet, A: abdominal wall, C: cryptorchidism, E: extra-genitourinary, generating the acronym RUBACE), yielding a potential summed score of 0-31.

Diagnostic Utility of a Likert Scale Versus Qualitative Descriptors and Length of Capsular Contact for Determining Extraprostatic Tumor Extension at Multiparametric Prostate MRI.

Objective: The purpose of this study is to determine the reproducibility and diagnostic performance of a Likert scale in comparison with the European Society of Urogenital Radiology (ESUR) criteria and tumor-pseudocapsule contact length (TCL) for the detection of extraprostatic extension (EPE) at multiparametric MRI.

Materials And Methods: This was a retrospective review of all men who underwent multiparametric MRI followed by prostatectomy between November 2015 and July 2016. Multiparametric 3-T MRI studies with an endorectal coil were independently reviewed by five readers who assigned the likelihood of EPE using a 1-5 Likert score, ESUR criteria, and TCL (> 10 mm).

Usage and survival implications of surgical staging of inguinal lymph nodes in intermediate- to high-risk, clinical localized penile cancer: A propensity-score matched analysis.

Objectives: To evaluate the usage of surgical staging of inguinal lymph nodes (SSILNs) in the United States for intermediate to high-risk, clinically localized penile squamous cell cancer (SCC), to explore patient and hospital factors associated with omission of this staging, and to evaluate the effect on survival.

Patients And Methods: Retrospective, observational study using the National Cancer Database from 2004 to 2014 of 1,689 men diagnosed with pT1b-T3, cN0 penile SCC, who by current guidelines should receive SSILNs-either by inguinal lymph node (ILN) dissection or sentinel node biopsy. Binomial logistic regression analysis was performed to determine predictors of SSILNs.

Differences at Presentation and Treatment of Testicular Cancer in Hispanic Men: Institutional and National Hospital-based Analyses.

Objective: To describe epidemiologic patterns, stage at presentation, histology, and treatment differences associated with Hispanic men diagnosed with testicular germ cell tumor (TGCT). Hispanics are the fastest growing demographic in the United States and reports suggest that the incidence of TGCT is rising most rapidly in this demographic, yet little is known about TGCTs in Hispanic patients.

Materials And Methods: We compared patient factors, tumor characteristics, treatment patterns, and outcomes of non-Hispanic white (NHW) vs Hispanic patients at our own institution in North Texas from 2010 to 2016.

Survival Outcomes of Men with Lymph Node-positive Prostate Cancer After Radical Prostatectomy: A Comparative Analysis of Different Postoperative Management Strategies.

Background: Optimal management of patients with lymph node metastasis (LNM) after radical prostatectomy (RP) remains undefined.

Objective: We evaluated the association between three different management strategies and survival in prostate cancer with LNM after RP.

Design, Setting, And Participants: We analyzed data of 1338 patients with LNM after RP from three tertiary care centers.

Improved Magnetic Resonance Imaging-Pathology Correlation With Imaging-Derived, 3D-Printed, Patient-Specific Whole-Mount Molds of the Prostate.

Objectives: The aim of this study was to compare the anatomical registration of preoperative magnetic resonance imaging (MRI) and prostate whole-mount obtained with 3D-printed, patient-specific, MRI-derived molds (PSM) versus conventional whole-mount sectioning (WMS).

Materials And Methods: Based on an a priori power analysis, this institutional review board-approved study prospectively included 50 consecutive men who underwent 3 T multiparametric prostate MRI followed by radical prostatectomy. Two blinded and independent readers (R1 and R2) outlined the contours of the prostate, tumor, peripheral, and transition zones in the MRI scans using regions of interest.

Formalin disinfection of prostate biopsy needles may reduce post-biopsy infectious complications.

Background: We sought to determine whether formalin disinfection of prostate biopsy needles between cores reduces post-biopsy urinary tract infections (UTIs).

Methods: We reviewed a single-surgeon experience of transrectal prostate biopsies from 2010 to 2014. Biopsies were performed in either an operative suite, where 10% formalin was used to disinfect the needle tip between each biopsy core, or an outpatient clinic, where formalin was not used.

Cell-cycle markers do not improve discrimination of EORTC and CUETO risk models in predicting recurrence and progression of non-muscle-invasive high-grade bladder cancer.

Purpose: To assess if a panel of cell-cycle markers could improve the discrimination of European Organization for Research and Treatment of Cancer (EORTC) and Spanish Urological Club for Oncological Treatment (CUETO) models in predicting recurrence and progression of high-grade non-muscle-invasive bladder cancer (NMIBC).

Materials And Methods: Between January 2007 and January 2012, every patient with high-grade NMIBC treated with transurethral resection of bladder underwent immunohistochemical staining for 5 biomarkers (p21, p27, p53, KI-67, and cyclin E1). We excluded patients who had muscle-insvasive disease, underwent early cystectomy, and those with incomplete follow-up.

Concordance in Biomarker Status Between Bladder Tumors at Time of Transurethral Resection and Subsequent Radical Cystectomy: Results of a 5-year Prospective Study.

Purpose: To assess the concordance rate in alterations of molecular markers at the time of transurethral resection (TUR) and subsequent radical cystectomy (RC) among patients with high-grade urothelial carcinoma of the bladder (UCB).

Methods: We prospectively performed immunohistochemical staining p53, p21, p27, Ki-67 and cyclin E1 on TUR and on RC specimens from 102 patients treated with RC and bilateral lymphadenectomy for high-grade UCB. We analyzed the concordance rate of individual markers and of the number of altered markers.
