Summary
Fibroepithelial polyps are rare causes of ureteropelvic junction obstruction in children. Surgical treatment with dismembered pyeloplasty is curative, with no observed recurrences in this study.
Area of Science:
- Pediatric Urology
- Surgical Pathology
Background:
- Fibroepithelial polyps are benign growths found in the urinary tract.
- Ureteropelvic junction obstruction can occur in children due to these polyps.
Purpose of the Study:
- To review institutional experience with pediatric ureteropelvic junction fibroepithelial polyps.
- To define the characteristics and treatment outcomes of these rare lesions.
Main Methods:
- Retrospective review of pediatric patients with ureteropelvic junction obstruction caused by fibroepithelial polyps (1967-2002).
- Analysis of patient demographics, clinical presentation, surgical management, and outcomes.
Main Results:
- Eleven cases of ureteropelvic junction obstruction due to fibroepithelial polyps in 9 children (0.5% of UPJO cases).
- Predominantly affected males (89%) and the left side (78%).
- Dismembered pyeloplasty was curative in all cases, with no recurrences during a mean follow-up of 44 months.
Conclusions:
- Fibroepithelial polyps are rare causes of pediatric ureteropelvic junction obstruction, with a predilection for males and the left side.
- Surgical excision and dismembered pyeloplasty provide a curative outcome.
- The etiology of these polyps remains unknown.

Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

The nervous system consists of complex motor neuron circuits, including upper motor neurons originating from the cerebral cortex and lower motor neurons starting in the spinal cord, coordinating both voluntary and involuntary movements. Among these, somatic motor neurons activate skeletal muscles and are classified into alpha, beta, and gamma types. Alpha neurons are vital for voluntary movement coordination, while gamma neurons adjust muscle spindle sensitivity, and the function of beta...

Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...
