Objective: To compare differences in bowel-specific quality of life (QOL), overall qQOL, and neurogenic bowel dysfunction (NBD) severity by bowel management program in patients with spina bifida (SB).

Methods: We performed a retrospective cross-sectional study of patients ≥12 years old at our multidisciplinary SB center who completed both a modified Peristeen NBD questionnaire (assessing bowel symptom severity and bowel-specific QOL) and the Patient-Reported Outcomes Measurement Information System Pediatric Global Health questionnaire (assessing overall QOL). Nested, multivariable models were fit for associations between outcomes and bowel management program (enemas, conservative management, and none).

Purpose: Various techniques for neovaginal construction have been employed in the pediatric and adult populations, including the use of intestinal segments, buccal mucosal grafts, and skin grafts. Small intestinal submucosa (SIS) extracellular matrix grafts have been described as a viable alternative, though prior experience is limited. Our purpose was to assess operative characteristics and patient outcomes with neovaginal construction using SIS grafts.

Article Synopsis
  • - The study aimed to explore how young adult males with spina bifida perceive and experience discussions about sexual health with their healthcare providers.
  • - Conducted through semi-structured interviews with 20 participants aged 18-29, the findings revealed barriers like discomfort when discussing sex and variability in preferences, as well as facilitators like having a good relationship with their urologist.
  • - Results suggest that while these young men want to talk about sexual health, clinical communications need to be tailored to individual preferences and readiness, indicating that current health guidelines may not fully meet their needs.

Objective: To outline our experimental gonadal tissue cryopreservation (GTC) protocol that does not disrupt the standard of care in medically-indicated gonadectomy for patients with differences of sex development, including highlighting the multidisciplinary collaborative protocol for when neoplasm is discovered in these cases.

Methods: Two patients with complete gonadal dysgenesis who were undergoing medically-indicated prophylactic bilateral gonadectomy elected to pursue GTC. Both were found to have germ cell neoplasia in situ on initial pathologic analysis, requiring recall of the gonadal tissue, which had been cryopreserved.

Purpose: While our institution has historically obtained a urine culture (UCx) from every child at the time of urodynamics (UDS), no consensus exists on UDS UCx utility, and practice varies widely. This study aims to prospectively study our symptomatic post-UDS UTI rate before and after implementing a targeted UCx protocol.

Materials And Methods: A 2-part prospective study of patients undergoing UDS at one pediatric hospital was undertaken, divided into Phase 1 (7/2016-6/2017) with routine UCx at the time of UDS and Phase 2 (7/2019-6/2020) after implementation of a protocol limiting UCx at the time of UDS to only a targeted subset of patients.

Introduction: Patients with neurogenic urinary incontinence due to an incompetent outlet may be offered bladder neck reconstruction, but the quest for the perfect surgical-outlet procedure continues. Our aim was to characterize continence and complications after modified Mitchell urethral lengthening/bladder neck reconstruction (MMBNR) with sling and to introduce a modification of exposure that facilitates subsequent steps of MMBNR.

Methods: A single-institution, retrospective cohort study of patients who underwent primary MMBNR between May 2011 and July 2019 was performed.

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.

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.
