[Correlation between pneumoperitoneum and surgical findings and morbidity and mortality in newborns with necrotising enterocolitis].

Introduction: Surgical intervention in necrotising enterocolitis (NEC) is correct when there is intestinal gangrene. This is evident when gangrene produces perforation and pneumoperitoneum, with this being the only universally accepted radiological indication for the surgical intervention of NEC.

Objective: To perform an analysis on patients with surgically managed NEC, including determining how the decision to intervene is reached, the outcomes, and if patients with perforation had a pneumoperitoneum.

Three-dimensional printed model of bilateral Wilms tumor: A useful tool for planning nephron sparing surgery.

Nephron sparing surgery (NSS) is increasingly utilized to treat patients with bilateral Wilms tumor. We present a case of NSS planning using a three-dimensional computerized and printed model of both kidneys with anatomical structures of interest (parenchyma, renal pelvis, major calyx, renal artery, renal vein, and tumor). This model allowed a better understanding of the anatomic relation between the tumor and the normal kidney on each side, improving the surgical planning and the preoperative discussion with the patient's family.

[Functional and aesthetic evaluation of sacrococcygeal teratomas. Not everything ends with surgery].

Introduction: Sacrococcygeal teratoma is the most common solid neonatal tumour. The improvement in survival has meant that postoperative sequelae can be diagnosed and treated. The aim of this article is to evaluate the long-term outcomes of patients treated in our centre.

Radiation-free monitoring in the long-term follow-up of pyeloplasty: Are ultrasound new parameters good enough to evaluate a successful procedure?

Introduction: Long-term evolution of residual hydronephrosis after successful pyeloplasty is not common. In this report, we have studied new ultrasound parameters, and have investigated the frequency of residual hydronephrosis. We highlight alternative radiation-free monitoring of pediatric pyeloplasties with ultrasound alone.

[Vesicovaginal Reflux and Urocolpos].

Objective: Vesico-vaginal reflux (VVR) is defined as the reflux of urine into the vaginal vault during voiding, occasionally seen in pre- adolescent girls. The typical history consists in post voiding leaks in the daytime, that correspond to the progressive urine discharge from the vagina, after it has been filled up during micturition. We intend to show two cases presenting with significant urocolpos.

Patient with disorganization syndrome: surgical procedures, pathology, and potential causes.

Background: The human disorganization syndrome (HDS) is an extremely rare malformation syndrome that presents with a severe pattern of defects affecting different structures.

Methods: We describe a newborn girl presenting with HDS. Her clinical features included a large appendage arising from the right buttock as the only alteration, with size and shape of a lower member-like structure, and a pedicle of the extra limb structure.
