Posterior rectal advancement with fistula preservation in patients with anorectal malformation. A multicenter study.

Background: Anorectal malformations (ARM) with rectoperineal fistula are mainly repaired with a posterior sagittal anorectoplasty (PSARP), which can be challenging given the proximity of the fistula to the vagina and urethra. The posterior rectal advancement anoplasty (PRAA), preserves the anterior wall of the fistula without leaving an anterior or a posterior sagittal incision. It is indicated for selected cases of ARM with rectoperineal fistula in which the anterior aspect of the fistula is partially surrounded by sphincter complex.

Augmentation cystoplasty in children with neuropathic bladder: long-term outcomes after 30 years experience.

Background: Augmentation cystoplasty (AC) is a useful alternative for the treatment of neuropathic bladder, although there are few studies reporting long-term results. We assess our experience over the last 30-years.

Methods: A retrospective study was conducted in patients with neuropathic bladder in whom AC was performed in our institution between 1990-2020.

Bladder duplication in a patient with a persistent urogenital sinus: Case report and systematic review of the literature.

Bladder duplication (BD) is a rare malformation that is often associated to other anomalies. We report a newborn diagnosed with BD in the sagittal plane, associated to persistent urogenital sinus (UGS), given the opening of the vagina immediately below the bladder neck. It is the fourth time this association is reported.

Long-term outcome of pediatric renal transplantation with donors younger than 6 years.

Background: Renal transplantation is currently the best treatment option for patients with end-stage renal disease. However, the use of kidneys from donors under 6 years of age as a possibility to increase the organ pool in pediatric recipients remains a controversial matter. We aimed to investigate whether donor age is associated to the long-term functionality of the renal graft.
