Hellenic Journal of Nuclear Medicine ñ September December 2007 of a colorectal or bladder malignancy [7]. Most vesicoenteric fistulas in children are congenital and associated with anorectal malformation or cloacal anomalies [8]. The clinical manifestations are principally urological in the form of recurrent urinary infection and terminal pneumaturia. The most useful diagnostic techniques are c...

The prune belly syndrome is a rare congenital anomaly which is characterized by the triad of an absent or a deficient development of the abdominal muscle, bilateral cryptorchidism and an anomalous urinary tract. In its full form, this condition occurs only in males. However, a similar condition occurs in females in the absence of cryptorchidism. On the other hand, the urorectal septum malformat...

Sirenomelia, also known as mermaid syndrome, is a developmental malformation of the caudal body characterized by leg fusion and associated anomalies of pelvic/urogenital organs including bladder, kidney, rectum and external genitalia. Most affected infants are stillborn, and the few born alive rarely survive beyond the neonatal period. Despite the many clinical studies of sirenomelia in humans,...

Cloacal malformation is an extremely rare fetal pathological condition that presents as a variety of defects. It predominantly affects females, with prevalence of 1 in 50,000 births. Prenatal ultrasonography on a 20-year-old caucasian woman (G4P1A2) at 33 weeks of pregnancy showed the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambiguous...

BACKGROUND During normal development in human and other placental mammals, the embryonic cloacal cavity separates along the axial longitudinal plane to give rise to the urethral system, ventrally, and the rectum, dorsally. Defects in cloacal development are very common and present clinically as a rectourethral fistula in about 1 in 5,000 live human births. Yet, the cellular mechanisms of cloaca...

Background: Hypospadias is the second most common congenital malformation in males and of penis. This characterized by anatomical position urinary tract opening on ventral or anterior part The prevalence hypospadias western countries around 8 1000 live births reported to increase every year.Methods: study a descriptive with retrospective cross-sectional approach. All data were retrieved from RS...

BACKGROUND AND OBJECTIVES The Exstrophy Complex (EC) is a serious malformation of midline abdominal wall. Wide pubis prevents approximating the lateralized rectus muscle and leads to dehiscence and fistula formation. Our aim was to recommend an easier method for abdominal wall closure in the Bladder Exstrophy (BE) complex repair. MATERIALS AND METHODS From November 2007 to April 2010, we had ...

We present the first experimental evidence that a bird is capable of evaporating enough water from the cloaca to be important for thermoregulation. We measured rates of evaporation occurring from the mouth, the skin, and the cloaca of Inca doves Columbina inca Lesson and Eurasian quail Coturnix coturnix Linnaeus. Inca doves showed no significant increase in cutaneous evaporation in response to ...
