Motivation: The motivation for the overview presented in this article is to provide a starting point for considering whether existing new product development methodology and its level of detail allows product teams to develop high-quality and business-effective product concepts. Aim: The aim of this article is recognise the current state of research into new product development methodology and to present the strategies and models for New Product Development (NPD). Materials and methods: The systematic review of the literature was applied in the article. Results: The first section outlines the main strategies for new product development and how they are divided by methodological stance, degree of planning, search pattern, focus and response. The second part discusses the known models of new product development including: the craft model and the 5 generations based on the innovation models described by Rothwell and the stages of the manufacturing process defined in the literature. Part four looks at new trends in new product development, including: Open Innovation, Rapid Product Development (RPD), Agile New Product Development (ANPD), Sustainable New Product development (SNPD), the Design Thinking method and the new technologies of Industry 4.0.

Introduction and aim. Renal abscess is a rare finding in the pediatric population, estimated at 0.2% of all intra-abdominal abscesses. The most common manifestations are fever, flank pain and simultaneously increased inflammatory markers in laboratory tests. Symptoms of this condition are non-specific and can be dismissed with other pathologies like renal tumor. Although the management is based on widespread antibiotic therapy, some cases need surgical intervention because of poor general condition and major diameter of abscess (>5 cm). We undertook this study to analyze the ultrasonography findings correlated with the clinical manifestations of renal abscesses in children that can potentially improve detecting renal abscesses in children earlier. Material and methods. We retrospectively studied 9 patients with renal abscesses treated in our hospital. Results. All patients were diagnosed with renal abscesses based on ultrasonography (US) examination and each of them had elevated inflammatory parameters at the time of admission. For treatment, all patients were treated with intravenous antibiotics and two of them were treated with surgical drainage. All study group recovered completely or received a reduction of abscesses diameters. The renal abscesses were monitored by ultrasonography. Conclusion. In our study, we assessed the usefulness of the US examination for diagnosis and treatment monitoring in pediatric patients. Ultrasonography is a gold standard due to its wide availability, noninvasiveness and low price.  It also allows for immediate diagnosis, which is crucial to institute proper treatment. Treatment of abscesses depends on the clinical condition of the patient, other comorbidities, imaging presentation and the size of the abscess.
