Introduction and objective: Bladder neuromodulation has emerged as a new alternative in the management of adults with bladder dysfunctions from a neuropathic origin. Despite the fact that, numerous studies have proven the efficacy and safety of this therapy in adults’ patients, there are however, still few studies that demonstrate its success in paediatric neuropathic bladder. Materials and methods: We perform a systematic review of the studies which analysed the impact of bladder electrostimulation in paediatric patients (0 to 18 years) with a neurogenic origin. The search identified 9716 potentially articles. Finally, 11 papers published between 1992 and 2019 fulfilled the necessary criteria to be part of our study and were selected for the systematic review. Results: We did not find a common trend among the results obtained from the studies included in the present review. Most of the studies demonstrated an optimal efficacy rate and high safety, but however the superiority of this therapy over anticholinergic drugs could not be established due the presented results. For this fact, these results continue to be controversial. Furthermore, the methodology between the different studies was very huge, which made it difficult to compare the results obtained from each one of them. Conclusions: Given the potential risk of renal failure presented by paediatric patients with neurogenic bladder, the therapeutic alternatives used in the management of this disease must have a proven efficacy. For this reason, and after the review, due the absence of evidence regarding bladder electrotherapy in this group of patients, its use should be limited and exceptional.

[Sacral electrical neurostimulation in the refractory pediatric overactive bladder].

Urinary incontinence is one of the principal reasons for visiting the urologist amongst paediatric patients, and an overactive bladder is the vesical dysfunction that most frequently provokes this. Currently the only medicine approved for managing an overactive bladder is oxybutynin; however, many patients respond partially to this therapy or are refractory to it. Vesical electrotherapy has emerged as a new alternative in the algorithm for managing patients with an overactive bladder refractory to anticholinergic medicines, but the evidence on this issue has to date been scant. We present the case of a 12-year-old patient with an overactive bladder refractory to oxybutynin and solifenacin who presented a good response to treatment with sacral vesical electrotherapy, with complete disappearance of the symptoms (diurnal incontinence and urgency of micturition) without adverse effects.

[DRESS syndrome, a differencial diagnosis in late postoperative complications]. / Síndrome de DRESS en el diagnóstico diferencial de las complicaciones postquirúrgicas.

The DRESS syndrome (drug rash with eosinophilia and systemic symptoms) is a serious pharmacodermia which must be taken into account when establishing an optimal early treatment to prevent a systemic and potentially lethal evolution. Pharmacodermias are the third most frequent cause of adverse effects during surgical hospitalization, after nosocomial infections and intraoperative complications. In most cases, they pose a challenge to the surgeon, since their onset is nonspecific and, therefore, can be easily mistaken for a surgery complication. We present the case of a 54-year-old man, healthy and without relevant background, who was operated on two times due to spontaneous abdominal bleeding. Three weeks after the last surgery, and coinciding with the administration of oral metamizole, the patient developed a DRESS syndrome. The initial unspecific deterioration, characteristic of this syndrome, is the main cause of the delay in diagnosis and correct treatment, causing the resulting evolution to systemic affectation.

[Appendicitis, an unusual cause of acute abdomen in neonatal patients. A case report]. / Apendicitis como causa de abdomen agudo en etapa neonatal. A propósito de un caso.

Appendicitis is the most frequent surgical disease in childhood, but it is very uncommon in the neonatal period. In this period of life, a delay in diagnosis (frequently due to the rareness of this pathology and lack of clinical suspicion) and consequently in therapeutic approach, frequently results in appendicular perforation and a subsequently poor evolution of this pathology. We present the case of a neonate with a history of Down's syndrome and Fallot's tetralogy. Due to her basal cardiopathy, she required surgical intervention to create a systemic-pulmonary fistula, as a temporary bridge until definitive cardiac surgery could be performed. In the postoperative period of this surgery she presented fever, acute abdomen and abdominal radiography compatible with pneumoperitoneum. An emergency laparotomy was performed, which revealed peritonitis secondary to a cecal gangrenous appendix with perforation in its middle third. Neonatal appendicitis is usually associated with diseases such as cystic fibrosis, necrotizing enterocolitis, or Hirschsprung's disease, as in the case of our patient. In neonates with acute abdomen and presence of pneumoperitoneum, appendicitis must be part of the differential diagnosis and requires urgent surgical intervention. Despite this, it presents a high rate of morbidity and mortality. Once the definitive diagnosis is made, any basal pathology that justifies its presence should be discarded.

Endoscopic balloon dilatation in primary obstructive megaureter: Long-term results.

BACKGROUND: Open neoureterocystostomy is the traditional surgical treatment for primary obstructive megaureter (POM). Endoscopic balloon dilation is a new minimally invasive alternative. It has been shown to be a safe and effective endoscopic procedure over short-term follow-up; however, few studies have shown its long-term efficacy. OBJECTIVE: The aim of this study was to evaluate the long-term results and complications of balloon dilation for the treatment of primary obstructive megaureter in infants. MATERIALS AND METHOD: A retrospective review was performed of patients with primary obstructive megaureter treated with balloon dilation. The diagnosis was made through ultrasonography, diuretic isotopic renogram, and voiding cystourethrogram (VCUG). The indications for surgery were: worsening hydronephrosis, renal function impairment, and recurrent urinary tract infections (UTI). All patients were followed 3 months after the endoscopic procedure with ultrasonography and MAG-3 renogram, and 6 months after surgery with VCUG and ultrasonography. Annual ultrasound and clinical follow-up were performed until present time. RESULTS: Seven boys and six girls were treated (median age 9 months, range 2-24). Ten patients had a prenatal diagnosis of hydronephrosis, and the diagnoses was made after UTI in three patients. No intraoperative complications were observed. One double-J stent was replaced after endoscopic procedure for malpositioning, and four patients developed UTIs after surgery. All patients had non-obstructive MAG-3 diuretic renogram 6 months after surgery. The mean washout on the renogram and the ultrasound pelvic diameter showed pre-operative and postoperative statistical differences (Summary Table). All patients maintained their results without recurrence or any other complications in the long-term follow-up. The median follow-up was 10.3 years (range 4.7-12.2). DISCUSION: In 2014, Aparicio et al. first described balloon dilation being used as a definitive treatment for primary obstructive megaureter in infants. Bujons et al. also presented 20 cases with a mean follow-up of 6.9 years. The current study is the largest to date, with a median follow-up of 10.2 years. It demonstrated the value of balloon dilation as a definitive treatment for POM. Despite these results, it was difficult to establish endoscopic balloon dilation as a definitive treatment for POM, due to the absence of long-term studies like the current one. CONCLUSION: Balloon dilation can be a safe and effective endoscopic procedure for the treatment of primary obstructive megaureter in infants, and has shown good outcomes in long-term follow-up. More studies are needed to demonstrate these results.

Orthotopic Liver Transplantation in an Adult With Biliary Atresia, Situs Inversus, and Inferior Cava Vein Absence: A Case Report.

BACKGROUND: We report the case of a 34-year-old man who underwent Kasai portoenterostomy for biliary atresia at 6 weeks of age. In 2011, pulmonary hypertension was diagnosed and he began treatment with sildenafil. In 2012, he presented with an episode of upper gastrointestinal bleeding secondary to esophageal varices resistant to treatment. Later, he exhibited liver dysfunction. He was included on the waiting list for transplantation on May 29, 2013, with a Model for End-stage Liver Disease score of 24. METHODS: He underwent liver transplantation with an isogroup graft from a brain dead donor on June 9, 2013. Native hepatectomy was laborious owing to important collateral circulation and adhesions after previous operations, which had injured loops of the small bowel (SB). Orthotopic implantation was accomplished with direct anastomosis of the upper liver cava vein to the right atrium of the receiver. Portal and arterial anastomoses were performed as usual. Biliary reconstruction surgery by hepatojejunostomy was delayed 24 hours owing to SB loops injuries. RESULTS: Graft viability was confirmed by normal hepatic function. Postoperative complications included abdominal compartment syndrome treated by decompressing laparotomy, severe pulmonary alveolar hemorrhage resolved with artery embolization and endotracheal intubation, intraabdominal abscess requiring percutaneous drain, and stroke requiring long-term rehabilitation. He is currently asymptomatic, presents normal graft function, and receives sildenafil because of pulmonary hypertension. CONCLUSIONS: The association of situs inversus and biliary atresia is low. There is no consensus on the optimal operative approach to liver transplantation. An individualized assessment and multidisciplinary patient management are required.
