“…Amnio-infusion in the context of reduced liquor, 3D/4D scanning and fetal MRI are further modalities of imaging that may increase diagnostic accuracy to help in counseling parents. Wang et al [12] reported their experience in the prenatal diagnosis of PST. Of the 22 fetuses with suspected PST, they correctly identified 13 of 14 cases with combined 2D and 3D ultrasonography.…”

“…3). Complete PST can be diagnosed by ultrasound in the sagittal plane when the scrotum is located above the penis; incomplete PST is identifiable in the coronal plane when the phallus is located in the middle of a divided scrotum [12]. Amnio-infusion in the context of reduced liquor, 3D/4D scanning and fetal MRI are further modalities of imaging that may increase diagnostic accuracy to help in counseling parents.…”

“…The introduction of 3DUS allowed the evaluation of the surface structures of the fetus in rendering mode, enabling the development of a new imaging method for evaluation of hypospadias [4–6]. Fang et al [5] described a case report of prenatal diagnosis of hypospadia in the 27th week of pregnancy, in which 3DUS rendering mode allowed a better evaluation of hypospadia.…”

“…They suggest the use of 3DUS in cases of reduced penis length or altered form analyzed with 2DUS. Wang et al [6] described two cases of prenatal diagnosis of penoscrotal hypospadias using 3DUS, with 27 and 32 weeks. These authors reported that 3DUS provides realistic images that can be shared by other professionals such as pediatric surgeons.…”

Hypospadia is an abnormal development of the corpus spongiosum, that involves cavernosa urethra, as a result of an inadequate fusion of the urethral folds. The incidence ranges from 0.2 to 4.1 per 1,000 live births. Among the markers of hypospadia, isolated ventral or lateral curvature of the penis associated with shortening are the most important markers and, in severe cases, can result in the classic “tulip sign.” The diagnosis of hypospadia is uncommon unless there is a routine of detailed analysis of fetal genitalia morphology. The prenatal diagnosis is of great importance for genetic counseling and allows better planning of postnatal treatment. The three-dimensional ultrasonography (3DUS) in rendering mode enables better comprehension of the pathology by parents, facilitating postnatal planning. We report a case of penoscrotal hypospadia diagnosed at 33 weeks of gestation, suspected due to the absence of testicles in the scrotum and difficulty of penis visualization. We emphasize the findings of 3DUS and its importance in the pathology compression by parents.

BackgroundThe aspect of sexual differentiation and the mechanism controlling the position of genitalia, which represents one of the most substantial differences between the sexes, is still poorly understood. Minor cases and some variants of penoscrotal transposition (PST) are unreported, and obvious cases were classified broadly and confused with other unrelated anomalies.MethodologyRelevant literature published till 2022 were reviewed then organized, recapitulated, and presented in comparison with the findings and data of 65 child diagnosed with PST. So, an integrated comprehensive approach to this uncommon condition enabled a new classification including few unreported variant cases, which were complemented.ResultsPST is classified herein into a cephalic or caudal scrotal migration, the cephalic type subdivided into major and minor subtypes the latter type subdivided into bilateral, unilateral or central subtypes. Cases of caudal scrotal regression is an unreported anomaly in which the scrotum located caudally, as constant association with epispadias/exstrophy anomalies leaving a wide distance between the fixed penis and the scrotal sacs.ConclusionPST is not rare as it was believed, it occurs in two directions; cephalic and caudal directions. Scrotal caudal regression anomaly was not described before, as well the PST presented as an inguinal hernia.

Prenatal Diagnosis of Penoscrotal Transposition With 2- and 3-Dimensional Ultrasonography

Abstract: The combination of 2DUS and 3DUS improved the prenatal detection rate for penoscrotal transposition compared with 2DUS alone.
