“…The PU:XU ratio for an ideal localization of umbilicus was calculated as 0.61 ± 0.12 in this study. 2 PU:XU ratio was 0.05 in our patient, which is approximately one-tenth of the ratio for ideal localization.…”

“…Few studies evaluated normal localization of the umbilicus in the newborn, which aid to improve cosmetic results after the repair of congenital abdominal wall defects. 2 3 6 These studies determined the position of umbilicus with respect to the xiphoid process and pubis in normal newborns. Distances between the xiphoid process and the center of the umbilicus (XU), the pubis and the center of the umbilicus (PU) were determined in a study.…”

We report the case of a male neonate with a low-set umbilicus. Physical examination revealed an appropriately grown term infant with no unusual findings, except ectopically placed umbilical cord at the level of the bladder in the hypogastric zone. The infant underwent detailed investigations that revealed no associated malformation. To the best of our knowledge, this is the first case with very distinct localization of the umbilicus without any congenital abnormalities.

“…A number of anatomical studies about the right and most natural position of the umbilicus have been published [8,9]. In adults it should be ideally located 1 cm under the line between the iliac crests [8], while in newborns it should be located two thirds down a vertical line between the xiphoid and the pubis [9].…”

“…In adults it should be ideally located 1 cm under the line between the iliac crests [8], while in newborns it should be located two thirds down a vertical line between the xiphoid and the pubis [9]. In view of all of these, a neoumbilicus or a flap to lower the native umbilicus could remain as better options.…”

Prune belly syndrome: modified Monfort abdominoplasty with a horizontal scar and a dermal layer

et al. 2015

Prune belly syndrome is a rare congenital disease occurring in 1/40,000 births, mostly in male patients. Abdominal hypoplasia has aesthetic and functional consequences on breathing, intestinal transit, and stature. Thus, the goal of the surgical treatment must be both functional and aesthetic. Through two cases, we p r e s e n t a m o d i f i e d t e c h n i q u e o f t h e u s u a l abdominoplasty to obtain better functional and aesthetic results. Two male patients have been operated on, when they, respectively, were 10 months old and 3 years old. Our surgical technique was inspired from Callia's as we used a horizontal incision, and from the Monfort abdominoplasty for the muscular wall repair, which we reinforced by preserving a dermal layer under the umbilicus. Patients have been followed up 1 to 2 years. We reported a functional and aesthetic improvement in both patients, and no complication occurred. These preliminary results showed satisfactory functional and aesthetic results with a hidden scar. Level of Evidence: Level V, therapeutic study.

Background Although there have been many reports concerning the normal position of the umbilicus, the measurements were performed from the surface of the body in all cases. We examined computed tomography (CT) images to determine the accurate position of the umbilicus in children. Methods We retrospectively examined the CT data of 120 Japanese children (60 boys, 60 girls). The angle between both iliac crests to the umbilicus (IU angle), the angle between both anterior superior iliac spines and the umbilicus (AU angle), and the ratio of the length from the xiphoid process to the umbilicus and length from the umbilicus to the pubic symphysis were measured. Results The mean AU angle was 33.7° ± 5.1°, showing the least data variations. A significant difference was noted in the AU angle between boys and girls (32.7° ± 4.6° and 34.6° ± 5.4° respectively; p = 0.04). When we defined the position of the umbilicus as an AU angle of 33° in boys and 35° in girls, 115 children (95.8%) fell within ±10°. Conclusions The AU angle is the preferable predictor of the umbilicus position in children.

Where should the Normal Position of the Umbilicus be in the Neonate?

Abstract: We suggest that the PU:XU ratio should be 0.61 offering an ideal localization in umbilical reconstruction.
