Objective Describe a case of cloaca prenatally diagnosed in one of a set of monoamniotic twins. Study Design Retrospective review of a case. Results Cloaca is one of the most complex and severe degrees of anorectal malformations in girls. We present a discordant cloaca in monoamniotic twins. Fetal ultrasound showed a female fetus with a pelvic midline cystic mass, a phallus-like structure, a pr...

This study aimed to investigate plumage conditions, injuries in the comb, cloaca, and feet at end of laying period (73 weeks age) native Atak‐S (A‐S) foreign Isa Brown (IB) Novogen White (NW) genotypes reared two different cage densities. A total 480 hens, including 160 each hybrid, were used present study. Each hybrid group was divided into subgroups containing eight (468.75 cm2/hen) 12 animal...

Cloacae were examined from male and female salamanders representing 12 genera and 22 species in the Salamandridae. All female salamandrids possess numerous sperm storage glands, spermathecae, in the roof of the cloaca, but intergeneric variation exists in the occurrence of additional cloacal glands. Pleurodeles and Tylototriton possess both vent and anterior ventral glands, and secondary loss h...

The vesico-ureteric junction (VUJ) forms through a complex developmental program that connects the primordium of the upper urinary tract [the nephric duct (ND)] with that of the lower urinary tract (the cloaca). The signals that orchestrate the various tissue interactions in this programare poorly understood. Here, we show that two members of the EphA subfamily of receptor tyrosine kinases, Eph...

Despite the high occurrence of congenital abnormalities of the lower urinary tract in humans, the molecular, cellular and morphological aspects of their development are still poorly understood. Here, we use a conditional knockout approach to inactivate within the nephric duct (ND) lineage the two effectors of the Hippo pathway, Yap and Taz. Deletion of Yap leads to hydronephrotic kidneys with b...

We report a case of full term female child having persistent cloaca who was diagnosed to have right lung agenesis on investigations.

Pelvic midline cystic mass associated with renal malformation represents typical imaging features of a cloacal anomaly. We report a case of persistent cloaca that was diagnosed antenatally with fetal ultrasonography and MRI.
