Quality of Life and Bladder Symptoms in Adolescents and Young Adults With Spina Bifida Who Catheterize via Urethra vs Catheterizable Channel.

PURPOSE: We sought to assess associations between health-related quality of life (QOL), bladder-related QOL, bladder symptoms, and bladder catheterization route among adolescents and young adults with spina bifida. MATERIALS AND METHODS: Clinical questionnaires administered to individuals ≥ 12 years old requiring catheterization between June 2019 to March 2020 in a spina bifida center were retrospectively analyzed. Questionnaires were completed in English or Spanish independently or with caregiver assistance. Medical records were reviewed for demographic and clinical characteristics. Primary exposure was catheterization route (urethra or channel). Primary outcome was health-related QOL, measured by Patient-Reported Outcomes Measurement Information System Pediatric Global Health 7 (PGH-7). Secondary outcomes were bladder-related QOL and bladder symptoms, measured by Neurogenic Bladder Symptom Score (NBSS). Nested, multivariable linear regression models assessed associations between catheterization route and questionnaire scores. RESULTS: Of 162 patients requiring catheterization, 146 completed both the PGH-7 and NBSS and were included. Seventy-three percent were catheterized via urethra and 27% via channel. Median age was 17.5 years (range 12-31), 58% of patients were female, and 80% had myelomeningocele. Urinary incontinence was more common among those who catheterized via urethra (60%) compared to channel (33%). On adjusted analyses, catheterization route was not significantly associated with PGH-7 or NBSS bladder-related QOL scores. More bladder symptoms were associated with worse bladder-related QOL. Patients who catheterized via channel had fewer bladder symptoms than those who catheterized via urethra. CONCLUSIONS: Catheterization route was not significantly associated with QOL. Though catheterization via channel was associated with fewer bladder symptoms, only degree of current bladder symptoms was significantly associated with bladder-related QOL.

Expert Consensus on Pediatric Urodynamics Reporting Using Modified Delphi Technique.

PURPOSE: Urodynamic testing (UDS) is an important tool in the management of pediatric lower urinary tract conditions. There have been notable efforts to standardize pediatric UDS nomenclature and technique, but no formal guidelines exist on essential elements to include in a clinical report. We sought to identify ideal structure and elements of a pediatric UDS assessment based on expert consensus. MATERIALS AND METHODS: Pediatric urologists regularly performing UDS were queried using a Delphi process. Participants were invited representing varied geographic, experience, and societal involvement. Participants underwent 3 rounds of questionnaires between November 2022 and August 2023 focusing on report organization, elements, definitions, and automated electronic health record clinical decision support. Professional billing requirements were also considered. Consensus was defined as 80% agreeing either in favor of or against a topic. Elements without consensus were discussed in subsequent rounds. RESULTS: A diverse sample of 30 providers, representing 27 institutions across 21 US states; Washington, District of Columbia; and Canada completed the study. Participants reported interpreting an average number of 5 UDS reports per week (range 1-22). The finalized consensus report identifies 93 elements that should be included in a pediatric UDS report based on applicable study conditions and findings. CONCLUSIONS: This consensus report details the key elements and structure agreed upon by an expert panel of pediatric urologists. Further standardization of documentation should aid collaboration and research for patients undergoing UDS. Based on this information, development of a standardized UDS report template using electronic health record implementation principles is underway, which will be openly available for pediatric urologists.

Male perspectives on clinical communication about sexual health in spina bifida.

AIM: To assess perspectives on clinical communication about sexual health in young adult males with spina bifida. METHOD: Semi-structured interviews were conducted between February and May 2021 with males at least 18 years of age with spina bifida to assess their perspectives and experiences of sexual health communication with clinicians. Demographic and clinical characteristics were obtained from chart review and a survey of patients. Interviews were transcribed verbatim, and conventional content analysis was used for transcript coding. RESULTS: Twenty individuals participated with a median age of 22 years 6 months (range 18-29 years). Sixteen had myelomeningocele. Most identified as heterosexual (n = 17) and not sexually active (n = 13). Barriers and facilitators of successful interactions were identified. Barriers for participants included general discomfort with talking about sex and variability in individual preferences for how conversations occur. Facilitators included participants' comfort with their urologist and discussing sex in relation to disability. Suggestions for improving discussions included (1) notifying individuals that discussion about sex will occur before clinic visits; (2) creating space for discussions; (3) respecting individuals' readiness to discuss; and (4) making discussions disability specific. INTERPRETATION: Young adult males with spina bifida are interested in discussing sexual health with their clinicians. Great variability exists about conversation preferences, emphasizing the need to individualize clinical communication about sex. Current health guidelines for males may not be in line with individuals' wishes. WHAT THIS PAPER ADDS: Great variability exists in individual preference around sexual health communication. Patient-level barriers hinder successful conversations about sex. Individuals have great insight into how conversations about sex can be improved.

"I Just Haven't Done Any of That": Applicability of the International Index of Erectile Function in Young Men With Spina Bifida.

PURPOSE: We evaluate the applicability of the International Index of Erectile Function in young men with spina bifida and identify spina bifida-specific sexual experiences not captured by this measure. MATERIALS AND METHODS: Semistructured interviews were conducted between February 2021 and May 2021 with men ≥18 years of age with spina bifida. The International Index of Erectile Function was completed by participants, and perspectives on its applicability were discussed. Participant experiences and perspectives around sexual health were discussed to identify aspects of the sexual experience not well captured by the International Index of Erectile Function. Demographic and clinical characteristics were obtained from a patient survey and chart review. Conventional content analysis framework was used for transcript coding. RESULTS: Of 30 eligible patients approached, 20 participated. Median age was 22.5 years (range 18-29), and 80% had myelomeningocele. Most identified as heterosexual (17/20, 85%), were not in a relationship (14/20, 70%), and were not currently sexually active (13/20, 65%). Some perceived the International Index of Erectile Function as applicable, while others reported it was not, as they do not define themselves as sexually active. Aspects of the sexual experience not captured by the International Index of Erectile Function included (1) lack of control over sexual function, (2) poor lower body sensation, (3) urinary incontinence, (4) spina bifida-specific physical limitations, and (5) psychosocial barriers. Participant suggestions for improving the International Index of Erectile Function to increase its applicability were identified. CONCLUSIONS: While many perceived the International Index of Erectile Function as applicable, the measure inadequately captures the diverse sexual experiences of young men with spina bifida. Disease-specific instruments to evaluate sexual health are needed in this population.

Longitudinal Trajectories of Clean Intermittent Catheterization Responsibility in Youths with Spina Bifida.

PURPOSE: Clean intermittent catheterization (CIC) responsibility among youths with spina bifida is not well studied. We sought to determine longitudinal trajectories of CIC responsibility to examine the transition of CIC responsibility from caregiver-CIC to self-CIC. MATERIALS AND METHODS: We performed a secondary analysis of a prospective cohort study of youths with spina bifida. Participants aged 8-15 years originally recruited from 4 hospitals and a statewide spina bifida association were followed every 2 years. Participants who required CIC were included. Group-based trajectory modeling was used to isolate distinct trajectories of CIC responsibility, which was the primary outcome and was graded from caregiver-CIC to shared-CIC to self-CIC. Predictors of trajectory group membership were entered into multivariate logistic regression models and included various demographic, clinical and psychosocial characteristics such as CIC adherence and CIC mastery. RESULTS: Of 140 youths in the original cohort study, 89 met eligibility criteria for this study. Mean age was 11 years at enrollment and 93% of patients had myelomeningocele. Two distinct trajectory groups emerged: 17% of patients had a low-flat trajectory and 83% had a high-increasing trajectory of CIC responsibility, with shared-CIC by age 8-9 years and increasing self-CIC responsibility thereafter. Significant predictors of group membership in the high-increasing trajectory group included less severe spinal lesion levels, higher CIC mastery and lower CIC adherence. CONCLUSIONS: Nearly 1 in 5 youths with spina bifida in our cohort persistently required caregiver-CIC over time, while the remainder achieved shared-CIC responsibility by age 8-9 years, with increasing self-CIC responsibility thereafter.

Variation in Definitions of Kidney Abnormality in Patients with Spina Bifida: A Systematic Scoping Review.

PURPOSE: We systematically reviewed the variability in definitions of kidney abnormality (KA) outcomes in individuals with spina bifida (SB). MATERIALS AND METHODS: A systematic scoping review was conducted using MEDLINE, Embase™, Cochrane Library, CINAHL, PsycInfo®, Web of Science™ and ClinicalTrials.gov for articles from time of database inception to September 2020. No language or patient age restrictions were applied. Primary research articles involving individuals with SB where KA was assessed as an outcome were included. Means of assessing KA and defining KA severity were abstracted. RESULTS: Of 2,034 articles found, 274 were included in the review. Most articles were published after 1990 (63.5%) and included pediatric-only populations (0-18 years; 60.5%). KA outcomes were identified by imaging-based anatomical outcomes (84.7%), serum-based outcomes (44.9%), imaging-based functional outcomes (5.5%), urine-based outcomes (3.3%) and diagnoses of end-stage kidney disease (2.6%) or chronic kidney disease otherwise unspecified (1.8%). Hydronephrosis was the most commonly used specific outcome (64.6%, 177/274) with 19.8% (35/177) of articles defining hydronephrosis severity. Hydronephrosis was used more frequently in articles with pediatric-only populations. Creatinine and cystatin-C were used in 82.1% (101/123) and 17.9% (22/123) of articles reporting serum-based outcomes, respectively, with 32.7% and 50.0% of articles defining estimated glomerular filtration rate (GFR) severity. Serum-based outcomes were more common in articles including adults >18 years. Measured GFR was assessed in 9.9% (27/274) of articles, with 44.4% (12/27) of articles defining GFR severity. CONCLUSIONS: Significant variability exists in how authors define KA with few specifically defining KA severity. Consensus and consistency in defining KA outcomes are needed.

The Association of Health Literacy with Health-Related Quality of Life in Youth and Young Adults with Spina Bifida: A Cross-Sectional Study.

OBJECTIVE: The objective of the study was to determine if health literacy is associated with health-related quality of life (HRQOL) in adolescents and young adults (AYAs) with spina bifida. STUDY DESIGN: Between June 2019 and March 2020, the Patient-Reported Outcome Measurement Information System Pediatric Global Health-7 (PGH-7), a measure of HRQOL, and the Brief Health Literacy Screening Tool (BRIEF) were administered to patients ≥12 years old with a diagnosis of spina bifida seen in our multidisciplinary spina bifida center. Questionnaires were completed at scheduled clinic visits. The primary outcome was the PGH-7 normalized T-score. The primary exposure was the BRIEF score. Demographic and clinical characteristics were obtained from the medical record. Nested, multivariable linear regression models assessed the association between health literacy and the PGH-7 score. RESULTS: Of 232 eligible patients who presented to clinic, 226 (97.4%) met inclusion criteria for this study. The median age was 17.0 years (range: 12-31). Most individuals were female (54.0%) and had myelomeningocele (61.5%). Inadequate, marginal, and adequate health literacy levels were reported by 35.0%, 28.3%, and 36.7% of individuals. In univariable analysis, higher health literacy levels were associated with higher PGH-7 scores. In nested, sequentially adjusted multivariable linear regression models, a higher health literacy level was associated with a stepwise increase in the PGH-7 score. In the fully adjusted model, adequate health literacy and marginal health literacy, compared with inadequate health literacy, were associated with increases in a PGH-7 score of 3.3 (95% CI: 0.2-6.3) and 1.1 (95% CI: -2.0 to 4.2), respectively. CONCLUSIONS: Health literacy was associated with HRQOL after adjusting for demographic and clinical factors. Strategies incorporating health literacy are needed to improve HRQOL in AYAs with spina bifida.

Botulinum toxin in patients at-risk for bladder augmentation: Durable impact or kicking the can?

PURPOSE: Deferring bladder augmentation (BA) may be desirable in a pediatric neurogenic bladder (NGB) with worsening compliance, but prior studies have questioned whether onabotulinum toxin A (BTX) demonstrates durable improvement in compliance. We present our overall experience with BTX and its role in mitigating the "at-risk" NGB, as determined by urodynamic characteristics. METHODS: A retrospective single-institution review of all BTX procedures performed during January 2010 to October 2018 was conducted. Patients with <12 months follow-up after first BTX injection were excluded. Urodynamic studies (UDS) were reviewed to assign National Spina Bifida Patient Registry (NSBPR) as well as institutionally developed (LCH) risk classification groups. Patients were considered "at-risk" for BA if they had any of the following: NSBPR risk grade of intermediate or hostile; LCH risk grades indicating end-fill pressure >25 cmH2 O or detrusor sphincter dyssynergia (DSD); upper tract changes including new hydronephrosis; new or worsening vesicoureteral reflux; or other signs of a hostile urinary tract (i.e., febrile UTIs). UDS risk grades pre and post-first BTX injection were compared in this "at-risk" group, when available. RESULTS: Thirty-nine patients underwent 162 injection procedures over a median follow-up of 65 months interquartile range (IQR 49-81). Median age at first BTX was 10 years and the median number of BTX injections per patient was 4 (IQR 2-7; range 1-12) with a median time of 6 months between injections (IQR 4-10). Twenty-six patients were deemed "at-risk" at the time of first BTX injection, and of those, 16 (61.5%) proceeded to BA at a median of 36 months (IQR 22.5-42). A small number (four) had BA due to upper tract changes or worsening pressures on BTX, while nine patients (five with CKD) proceeded to BA given a lack of sufficient improvement to consider BTX a long-term viable option. Post-first BTX UDS demonstrated downgrading of risk group in 38% and 63% using NSBPR and LCH classifications, respectively. CONCLUSIONS: Encouraging improvements in the urodynamic risk group were noted in some patients. With careful counseling and follow-up, BTX may safely extend the time to BA in some "at-risk" patients.

Multidisciplinary spina bifida clinic: the Chicago experience.

Open spina bifida (open SB) is the most complex congenital abnormality of the central nervous system compatible with long-term survival. Multidisciplinary care is required to address the effect of this disease on the neurological, musculoskeletal, genitourinary, and gastrointestinal systems, as well as the complex psychosocial impact on the developing child. Individuals with SB benefit from the involvement of neurosurgeons, orthopedic surgeons, urologists, physical medicine and rehabilitation specialists, pediatricians, psychologists, physical/occupational/speech therapists, social workers, nurse coordinators, and other personnel. Multidisciplinary clinics are the gold standard for coordinated, optimal medical and surgical care. Ann and Robert H. Lurie Children's Hospital, formerly known as Children's Memorial Hospital, was one of the first hospitals in the USA to manage patients with this complex disease in a multidisciplinary manner. We describe the longitudinal experience of the multidisciplinary Spina Bifida Center at our institution and highlight the advances that have arisen from this care model over time. This clinic serves as an exemplar of organized, effective, and patient-centered approach to the comprehensive care of people living with open SB.

Proximal Hypospadias and Acquired Cryptorchidism: Incidence, Morphology and Potential Clinical Implications.

PURPOSE: We identified the incidence of acquired cryptorchidism among patients with proximal and mid shaft hypospadias, predictors of acquired cryptorchidism, and the prevalence of testis-epididymis nonfusion with ascended testes. We hypothesized that proximal hypospadias would be associated with higher incidence of acquired cryptorchidism than mid shaft hypospadias, and that ascended testes would exhibit increased prevalence of testis-epididymis nonfusion similar to anatomical findings in an undescended testis. MATERIALS AND METHODS: A retrospective cohort study of patients who underwent primary proximal and mid shaft hypospadias repair from 2010 to 2016 was conducted. Clinical and operative notes were reviewed. Patients with congenitally undescended testes or differences of sex development were excluded. RESULTS: A total of 175 patients were identified. Those with proximal hypospadias (14/104, 13%) were more likely than those with mid shaft hypospadias (1/71, 1%) to develop acquired cryptorchidism (p=0.04). Among proximal hypospadias patients, increased risk of acquired cryptorchidism was associated with pre-term birth (p <0.01) and penoscrotal transposition (p=0.01) but not with testis position on initial examination (p >0.99). In the 14 proximal hypospadias patients with acquired cryptorchidism, 21 ascended testes underwent orchiopexy. Operative notes adequately described testis-epididymis anatomy for 8/21 ascended testes. Testis-epididymis nonfusion was described in 6/8 ascended testes. CONCLUSIONS: Risk of acquired cryptorchidism is increased among patients with proximal hypospadias. Operative notes revealed a high rate of epididymal nonfusion with ascended testes, suggesting these testes morphologically resemble undescended testes. Close followup of testis position is needed in these patients, and the threshold to perform orchiopexy may need to be lower in select patients.

Diagnostic Test Characteristics of Ultrasound Based Hydronephrosis in Identifying Low Kidney Function in Young Patients with Spina Bifida: A Retrospective Cohort Study.

PURPOSE: Kidney dysfunction in spina bifida is usually detected by low estimated glomerular filtration rate or ultrasound based hydronephrosis. We assessed the diagnostic test characteristics of hydronephrosis for detecting low estimated glomerular filtration rate, hypothesizing that hydronephrosis has low sensitivity compared to cystatin C based estimated glomerular filtration rate. MATERIALS AND METHODS: We conducted a single center, retrospective cohort study, including patients with spina bifida from 2012-2017 with 2 kidneys and complete data needed to calculate estimated glomerular filtration rate via multiple pediatric (age 1-17.9 years) or adult (age ≥18 years) estimating equations. We evaluated the association of hydronephrosis status (high grade, low grade or none) with estimated glomerular filtration rate, adjusting for small kidney size and scarring, and calculated diagnostic test characteristics of hydronephrosis for low estimated glomerular filtration rate. RESULTS: We analyzed 247 patients (176 children and 71 adults). Mean±SD age was 13.7±6.6 years, and 81% of patients had myelomeningocele. Hydronephrosis (77% low grade) was found in 35/176 children and 18/71 adults. Hydronephrosis was associated with low estimated glomerular filtration rate in stepwise fashion, independent of kidney size and scarring. However, across cystatin C based pediatric equations, any hydronephrosis (compared to none) had 23%-48% sensitivity, and high grade hydronephrosis (compared to none or low grade) had 4%-15% sensitivity for estimated glomerular filtration rate <90 ml/min/1.73 m2, which remained unchanged after excluding small kidneys and scarring. Across cystatin C based adult equations, any and high grade hydronephrosis had 55%-75% and 40%-100% sensitivity, respectively, for estimated glomerular filtration rate <90 ml/min/1.73 m2, although with wide confidence intervals. Specificity was higher with high grade vs any hydronephrosis. Sensitivities were higher for estimated glomerular filtration rate <60 ml/min/1.73 m2. CONCLUSIONS: Hydronephrosis was associated with low estimated glomerular filtration rate but had poor sensitivity for cystatin C based estimated glomerular filtration rate <90 ml/min/1.73 m2, especially among children with spina bifida.

Chronic kidney disease and upper tract concerns after congenital and acquired urinary tract abnormalities: considerations for transition of care in teens and young adults.

PURPOSE: To emphasize the burden that chronic kidney disease (CKD) and its complications place on overall health and well-being over the lifetime in individuals with congenital and acquired urinary tract abnormalities. METHODS: Topic-based literature review was performed and professional opinion was obtained to describe the scope of medical challenges faced by both teens and adults and their health care providers in the context of congenital and acquired urinary tract abnormalities. RESULTS: Challenges include accurate assessment of glomerular filtration rate; engaging for consistent surveillance of blood pressure, proteinuria, and medical complications of CKD that increase the risk of progression to end-stage renal disease and affect general health; achieving early referral to nephrology for better outcomes; managing renal complications within the unique limitations of lower urinary tract function; treating upper tract urolithiasis in the atypical urinary tract; and preparing for successful renal transplant. CONCLUSION: In individuals with congenital or acquired abnormalities of the urinary tract, there is an inherent risk of CKD with its associated morbidity and increased mortality risk. Interplay between the upper and lower urinary tract impacts CKD progression. Collaborative management between urology and nephrology is highly recommended to address the unique challenges for each individual over the lifetime.

Distress Trajectories for Parents of Children With DSD: A Growth Mixture Model.

OBJECTIVE: This study identifies trajectories of parent depressive symptoms after having a child born with genital atypia due to a disorder/difference of sex development (DSD) or congenital adrenal hyperplasia (CAH) and across the first year postgenitoplasty (for parents who opted for surgery) or postbaseline (for parents who elected against surgery for their child). Hypotheses for four trajectory classes were guided by parent distress patterns previously identified among other medical conditions. METHODS: Participants included 70 mothers and 50 fathers of 71 children diagnosed with a DSD or CAH with reported moderate to high genital atypia. Parents were recruited from 11 US DSD specialty clinics within 2 years of the child's birth and prior to genitoplasty. A growth mixture model (GMM) was conducted to identify classes of parent depressive symptoms over time. RESULTS: The best fitting model was a five-class linear GMM with freely estimated intercept variance. The classes identified were termed "Resilient," "Recovery," "Chronic," "Escalating," and "Elevated Partial Recovery." Four classes have previously been identified for other pediatric illnesses; however, a fifth class was also identified. The majority of parents were classified in the "Resilient" class (67.6%). CONCLUSIONS: This study provides new knowledge about the trajectories of depressive symptoms for parents of children with DSD. Future studies are needed to identify developmental, medical, or familial predictors of these trajectories.

Proximal Hypospadias-Isolated Genital Condition or Marker of More?

PURPOSE: The prevalence of endocrine/genetic anomalies in boys with proximal hypospadias is unknown. We describe an endocrine/genetic evaluation for boys with proximal hypospadias to determine who may have a difference/disorder of sex development and/or benefit from additional testing. MATERIALS AND METHODS: We retrospectively reviewed boys with hypospadias seen at our hospital between January 2013 and October 2018. Those with proximal (penoscrotal, scrotal, perineal) hypospadias who presented before age 6 months and underwent endocrine/genetic testing were included. Demographics, test results, testicular examination at presentation, comorbidities and diagnoses were abstracted. RESULTS: A total of 1,789 boys with hypospadias were identified. Of 131 boys with proximal hypospadias all 60 who underwent endocrine/genetic evaluation were included. Most of these patients had bilateral palpable testes (52, 86%) that were fully descended (41, 68%). Associated anatomical anomalies were found in 53% of patients. All boys underwent endocrine testing, which was completely typical for a male infant in most (41, 68%). Common genetic tests included karyotyping (100%), microarray (38%) and multigene panel (13%). Genetic anomalies were found in 17 boys (28%), including 7 of 41 (17%) with bilateral descended testes and 10 of 19 (53%) with 1 or more undescended testes (p=0.01). Six of 8 boys with at least 1 nonpalpable testis had a genetic anomaly vs 11 of 52 with bilateral palpable testes (p=0.005). Differences/disorders of sex development were found in 9 patients (15%). CONCLUSIONS: Of 60 boys with proximal hypospadias 53% had nongenital anomalies, 28% had genetic anomalies and 15% had a difference/disorder of sex development. Although endocrine testing was clinically useful, genetic testing was most diagnostically revealing. Endocrine/genetic evaluation should be considered for boys with proximal hypospadias.

Kidney Function Surveillance in the National Spina Bifida Patient Registry: A Retrospective Cohort Study.

PURPOSE: Chronic kidney disease affects 25% to 50% of patients with spina bifida. Guidelines recommend kidney function surveillance in these patients but practice patterns are unknown. Variations in kidney function surveillance were assessed in patients with spina bifida based on the hypothesis that the treating clinic and spina bifida type would be associated with kidney function surveillance. MATERIALS AND METHODS: A retrospective cohort study was conducted of U.S. patients in the National Spina Bifida Patient Registry from 2013 to 2018. Followup was anchored at the 2013 visit. Participants with either an outcome event within 2 years of followup or more than 2 years of followup without an outcome event were included. Primary outcome was kidney function surveillance, defined as at least 1 renal ultrasound and serum creatinine within 2 years of followup. Primary exposures were clinic and spina bifida type, which were analyzed with covariates including sociodemographic and clinical characteristics in logistic regression models for their association with the outcome. Sensitivity analyses were performed using different kidney function surveillance definitions. RESULTS: Of 8,351 patients 5,445 were included with a median followup of 3.0 years. Across 23 treating clinics kidney function surveillance rates averaged 62% (range 6% to 100%). In multivariable models kidney function surveillance was associated with treating clinic, younger patient age, functional lesion level, nonambulatory status and prior bladder augmentation. Treating clinic remained a significant predictor of kidney function surveillance in all sensitivity analyses. CONCLUSIONS: Within the National Spina Bifida Patient Registry wide variation exists in practice of kidney function surveillance across treating clinics despite adjustment for key patient characteristics.

Establishing an Institutional Gonadal Tissue Cryopreservation Protocol for Patients with Differences of Sex Development.

PURPOSE: Many individuals with differences of sex development experience subfertility. We describe a novel gonadal tissue cryopreservation protocol for those individuals. MATERIALS AND METHODS: Before 2018 patients with differences of sex development electing gonadal tissue cryopreservation were enrolled in a cancer focused protocol. Thereafter, our hospital developed a protocol specifically for these patients undergoing gonadectomy due to neoplasia risk. Protocol development steps and procedures are reported. A retrospective chart review was conducted for patient characteristics and cryopreservation choices. RESULTS: During the institutional review board approval process there were multidisciplinary meetings with stakeholders. The main concerns discussed included preoperative counseling, pathological evaluation and final tissue disposition. Detailed multidisciplinary preoperative counseling is provided regarding potential gonadal tissue cryopreservation for patients undergoing gonadectomy. For enrolled patients the gonad is bisected after removal, with half being sent to pathology and half being processed for cryopreservation. If neoplasia is noted, cryopreserved tissue is recalled for further pathological analysis. Postoperative counseling is performed after pathology results are available, and the final gonadal tissue cryopreservation decision is made. During the study period 7 patients with 5 diagnoses and a median age of 10.99 years (IQR 1.29 to 14.84) elected to attempt gonadal tissue cryopreservation. Of the patients 4 (57%) had germ cells and elected to store tissue. CONCLUSIONS: Gonadal tissue cryopreservation at the time of gonadectomy is feasible for patients with differences of sex development at risk for gonadal neoplasia. The protocol described represents a template for institutions wishing to offer gonadal tissue cryopreservation to patients electing gonadectomy. More than half of patients thus far have cryopreserved gonadal tissue.

Patient and Caregiver Attitudes toward Disorders of Sex Development Nomenclature.

PURPOSE: The medical terminology applied to differences/disorders of sex development has been viewed negatively by some affected individuals. A clinical population of patients with differences/disorders of sex development and their caregivers were surveyed regarding current nomenclature, hypothesizing that those unaffiliated with support groups would have more favorable attitudes. MATERIALS AND METHODS: We recruited English and Spanish speaking patients 13 years old or older with differences/disorders of sex development and their caregivers at 5 national tertiary care clinics from July 2016 to December 2018. No diagnoses were excluded. Participants completed a survey rating terminology commonly applied to differences/disorders of sex development. Responses were compared between subgroups, including members vs nonmembers of a support group. RESULTS: Of 185 potential participants approached 133 completed the survey (72% response rate). Congenital adrenal hyperplasia (33%) was the most common diagnosis. "Variation of sex development" was the most liked term (37%) but was not liked more significantly than "disorders of sex development" (27%, p=0.16). No term was liked by a majority of respondents. "Disorders of sex development" (37%) and "intersex" (53%) were the only terms most frequently viewed unfavorably. Support group members were significantly more likely to dislike the term "intersex" (p=0.02) and to like "variation of sex development" (p=0.02). CONCLUSIONS: A clinical population of patients and their caregivers had generally neutral attitudes toward nomenclature applied to differences/disorders of sex development. Members of a support group had clearer terminology preferences. "Variation of sex development" was the most liked term, and "disorders of sex development" and "intersex" were the most disliked. No term was liked by most respondents, and no clear alternative to the present nomenclature was identified.

Illness Uncertainty Longitudinally Predicts Distress Among Caregivers of Children Born With DSD.

OBJECTIVE: A subset of parents of children with disorders/differences of sex development (DSD) including ambiguous genitalia experience clinically elevated levels of anxious and depressive symptoms. Research indicates that uncertainty about their child's DSD is associated with parent psychosocial distress; however, previous studies have been cross-sectional or correlational in nature. The current study is the first to examine the longitudinal trajectory of the relationship between caregiver-perceived uncertainty about their child's DSD and caregiver anxious and depressive symptoms across the first 12 months following genital surgery in young children, or if surgery was not performed, the first 12 months following study entry. METHODS: One hundred and thirteen caregivers (Mage = 32.12; 57.5% mothers; 72.6% Caucasian) of children (N = 70; Mage = 9.81 months; 65.7% female) with DSD were recruited from 12 DSD specialty clinics in the United States. Caregivers completed psychosocial measures at baseline, 6 and 12 months following genitoplasty, or study entry if parents elected not to have surgery for their child. RESULTS: Caregiver illness uncertainty and both anxious and depressive symptoms were highest at baseline and decreased over time (ps < .05). Caregiver illness uncertainty predicted symptoms of anxious and depressive symptoms across all time points (ps < .05). CONCLUSIONS: Caregivers' perceptions of uncertainty about their child's DSD are highest soon after diagnosis, and uncertainty continues to predict both anxious and depressive symptoms across time. Thus, the initial diagnostic period is a critical time for psychological assessment and intervention, with parent illness uncertainty being an important clinical target.

Estimated kidney function in children and young adults with spina bifida: A retrospective cohort study.

AIMS: Current estimated glomerular filtration rate (eGFR) equations may be inaccurate in patients with spina bifida (SB) because of reduced muscle mass and stature. Cross-sectional and longitudinal variability of eGFR were analyzed in these patients across multiple equations, hypothesizing greater variability in creatinine-based than cystatin-C (Cys-C)-based equations. METHODS: This retrospective cohort study included children (age, 1-17.9 years) and adults (≥18 years) with SB from 2002-2017 at a large SB clinic. Those without all data needed to calculate eGFR were excluded. Four pediatric and three adult eGFR equations were compared for cross-sectional outcomes of eGFR and elevated office blood pressures using chronic kidney disease (CKD) stage classification, and for longitudinal outcome of eGFR slope over time using covariance pattern models accounting for repeated measures. RESULTS: One hundred and eighty two children and 75 adults had greater than or equal to 1 set of data measurements; 118 and 52, respectively, had greater than or equal to 2 sets. The pediatric bedside Schwartz equation had the highest median eGFR and coefficient of variation. CKD stage classification by eGFR showed large differences across equations in children, with rates of eGFR < 60 and <90 ml/min/1.73 m2 ranging from 2%-9% and 5%-69%, respectively. Only one equation showed a significant inverse association between eGFR and blood pressure. Longitudinally, eGFR slopes over time were different across pediatric equations (P < .001) but not adult equations. The bedside Schwartz equation had a positive eGFR slope; the other Cys-C-containing equations had negative slopes. CONCLUSIONS: Creatinine-based equations in children with SB vary considerably from cystatin-C-containing equations in calculating both single point-in-time eGFR values and eGFR trends over time.
