Background: Posterior retroperitoneoscopic adrenalectomy has several advantages over transabdominal laparoscopic adrenalectomy regarding operating time, blood loss, postoperative pain, and recovery. However, postoperatively several patients report chronic pain or hypoesthesia. We hypothesized that these symptoms may be the result of damage to the subcostal nerve, because it passes the surgical area.

Background And Objective: We present an overview of the 2024 updates for the European Association of Urology (EAU)/European Society for Paediatric Urology (ESPU) guidelines on paediatric urology to offer evidence-based standards for perioperative management, minimally invasive surgery (MIS), hydrocele, congenital lower urinary tract obstruction (CLUTO), trauma/emergencies, and fertility preservation.

Methods: A broad literature search was performed for each condition. Recommendations were developed and rated as strong or weak on the basis of the quality of the evidence, the benefit/harm ratio, and potential patient preferences.

Background And Objective: The prescriptive literature on vesicoureteral reflux (VUR) is still limited and thus the level of evidence is generally low. The aim of these guidelines is to provide a practical approach to the treatment of VUR that is based on risk analysis and selective indications for both diagnostic tests and interventions. We provide a 2023 update on the chapter on VUR in children from the European Association of Urology (EAU) and European Society for Paediatric Urology (ESPU) guidelines.

Introduction: Historically, ureteral reimplantation (UR) has been the gold standard for treatment of primary obstructive megaureter (POM) with declining renal function, worsening obstruction, or recurrent urinary tract infections. In infants, open surgery with reimplantation of a grossly dilated ureter into a small bladder, can be technically challenging with significant morbidity. Therefore, less invasive endoscopic management such as dilatation or incision of the ureter-vesical junction, has emerged as an alternative to reimplantation during the last decades.

Thulium laser (ThL) has become popular in urology, because of its powerful action on tissue, achieving optimal ablation and hemostasis. Aim of our article was to evaluate efficacy of ThL in infants affected by posterior urethral valve (PUV) ablation. Clinical charts of 25 infants (age ≤12 months) who underwent PUV ablation were retrospectively reviewed.

Article Synopsis
  • Minimally invasive adrenalectomy is commonly performed for small adrenal tumors, but this study focuses on the prevalence of chronic postsurgical pain, which hasn't been extensively researched before.
  • A total of 602 patients underwent the surgery between 2007 and 2019, with 14.9% experiencing chronic pain afterward, and 33% of those with pain also reported localized hypoesthesia (reduced sensation).
  • Young age emerged as a notable risk factor for chronic pain, and patients experiencing this pain reported a significantly lower quality of life compared to those without pain.*

Background: Posterior retroperitoneoscopic adrenalectomy (PRA) has several advantages over transperitoneal laparoscopic adrenalectomy (TLA) regarding operative time, blood loss, postoperative pain, and recovery. However, it can be a technically challenging procedure. To improve patient selection for PRA, we developed a preoperative nomogram to predict operative time.

Article Synopsis
  • * Retrospective analysis involved 44 pediatric patients, revealing an average blood loss of 55 ml per kg, with many receiving red blood cells (average of 38 ml per kg) and fresh frozen plasma (average of 28 ml per kg). Longer surgery times and lower patient body weight were linked to increased bleeding and transfusions.
  • * The findings suggest high rates of blood loss and transfusions during craniosynostotic corrections and propose potential solutions, such as forming specialized medical teams, adopting minimally invasive techniques, and optimizing anesthesia to reduce the need
