Urological evaluation of patients that had undergone in utero myelomeningocele closure: A prospective assessment at first presentation and early follow-up. Do their bladder benefit from it? | LitMetric
Aims: To report our data on initial urological presentation after in utero myelomeningocele (MMC) closure.
Methods: A prospective urological assessment at first presentation was designed for patients that had undergone in utero MMC closure and referred to our urological facility. The protocol consisted of detailed medical history, renal sonography, voiding cystourethrogram, and urodynamic evaluation.
Results: In utero MMC closure was performed in 19 patients at gestational age of 25.6 weeks 25-27. Birth occurred at a mean gestational age of 31.8 weeks 26-36. Hyperactive bladder was observed in 89.5% 17/19. Bladder compliance was normal in two cases (10.5%), was markedly reduced in 10 patients (52.6%) and not possible to be determined due to urinary leakage in 7 patients (36.8%). We observed normal bladder capacity in 8 patients (42.1%), reduced in 11 (57.9%), and detrusor-sphincter dyssynergia in 9 patients (47.4%). Underactive bladder was diagnosed in one case. Clean Intermittent Catheterization was initiated by 11 patients (57.9%) mostly in association with anticholinergics 10/11. Vesicoureteral reflux was found in 5 patients (26.3%) and 9 had pyelonephritis at a mean follow-up of 5.4 months 2-17.
Conclusions: Our data suggested that despite in utero MMC surgery, patients are at risk for bladder abnormal function and renal deterioration and should be aggressively treated, not differently from those operated in the post-natal term. This study has the merit of being a prospectively set evaluation performed by one investigator, including the urodynamic study. We acknowledge the need of long-term follow up.
Objective: Myelomeningocele (MMC) carries high morbidity and mortality. The Management of Myelomeningocele Study (MOMS) showed improved outcomes after prenatal compared to postnatal repair. However, it is unclear how the MOMS trial affected practice and outcomes in the Latin American region.
(1) : Fetal surgery for meningomyelocele (MMC) should reduce the occurrence of Arnold-Chiari malformations, hydrocephalus, the associated need for craniocervical decompression, and the need for cerebrospinal fluid shunt insertion. Fetal surgery should improve ambulatory status. (2) : We used retrospective analysis of the documentation and descriptive statistics to summarize the clinical data and measured MRI parameters.
The introduction of self-sampling in cervical cancer screening has raised the importance of HPV test validation on self-collected samples. This study aimed to evaluate the clinical accuracy of the OncoPredict HPV Screening (SCR) assay on self-collected vaginal and first-void urine (FVU) samples, relative to cervical specimens, using the VALHUDES Framework. FVU and vaginal self-samples followed by a clinician-collected cervical brushing were collected from 500 women referred to colposcopy and tested using OncoPredict HPV SCR assay.
HIV exposed but uninfected infants (iHEU) display altered immunity and are at increased risk of infection. We previously reported that iHEU have decreased maternal microchimerism (MMc)-maternal cells transferred to the offspring in utero/during breastfeeding. We quantified MMc in T cell subpopulations in iHEU and unexposed infants (iHU) to determine whether a selective deficiency in MMc contributes to altered cellular immunity.
A study was conducted to analyze neurogenic bladder function in patients who underwent different surgical repairs for myelomeningocele (MMC), focusing on those who received in-utero surgery versus postnatal treatment.
The research utilized a database created from 2018 to 2023 to track bladder function outcomes, complications like hydronephrosis, and treatment effectiveness across varied MMC repair methods.
Preliminary findings suggest that in-utero MMC closure does not lead to improved bladder function compared to postnatal surgical options, contrasting previous beliefs based on the MOMS study data.
