Infants with the disorder exhibit an inverted smile; they appear to be crying when they are actually smiling, in conjunction with uropathy. They also may be affected by hydronephrosis. Symptoms of this disease can start at very young ages. Many people with this syndrome will die in their teens to early 20s because of the renal failure (uropathy) if not diagnosed and treated. Children with the syndrome have abnormal facial development that cause an inverted smile, nerve connections are however normal. When attempting to smile, the child will appear to cry. Urinary problems arise as a result of a neurogenic bladder. Most patients older than the age of toilet training, present with enuresis, urinary-tract infection, hydronephrosis, and a spectrum of radiological abnormalities typical of obstructive or neurogenic bladders. Radiological abnormalities include things such as: trabeculated bladder, vesicoureteral reflex, external sphincter spasm, pyelonephritis, hyperreflexic bladder, noninhibited detrusor contraction, etc.. Urinary abnormalities might result in renal deterioration and failure. This can be prevented by taking proper measures to restore normal micturition and by taking antibiotics to prevent infections. In some cases, the affected patients become hypertensive and progress to end-stage renal disease, while others become uremic. Additionally, most patients suffer from constipation.

Early detection of this syndrome is possible through the peculiar faces that children present.

Urofacial syndrome ( or hydronephrosis with peculiar facial expression), is an autosomal recessive congenital disorder characterized by inverted facial expressions in association with obstructive disease of the urinary tract. The inverted facial expression presented by children with this syndrome allows for early detection of the syndrome, this inverted smile is easy to see when the child is smiling and laughing. Early detection is vital for establishing a better prognosis as urinary related problems associated with this disease can cause harm if left untreated. Incontinence is another easily detectable symptom of the syndrome that is due to detrusor-sphincter discoordination, although it can easily be mistaken for pyelonephritis.

It may be associated with "HPSE2".

Hand-foot-genital syndrome (HFGS) is characterized by limb malformations and urogenital defects. Mild bilateral shortening of the thumbs and great toes, caused primarily by shortening of the distal phalanx and/or the first metacarpal or metatarsal, is the most common limb malformation and results in impaired dexterity or apposition of the thumbs. Urogenital abnormalities include abnormalities of the ureters and urethra and various degrees of incomplete Müllerian fusion in females and hypospadias of variable severity with or without chordee in males. Vesicoureteral reflux, recurrent urinary tract infections, and chronic pyelonephritis are common; fertility is normal.

When a diagnosis of multicystic kidney is made in utero by ultrasound, the disease is found to be bilateral in many cases. Those with bilateral disease often have other severe deformities or polysystemic malformation syndromes. In bilateral cases, the newborn has the classic characteristic of Potter's syndrome.

The bilateral condition is incompatible with survival, as the contralateral system frequently is abnormal as well. Contralateral ureteropelvic junction obstruction is found in 3% to 12% of infants with multicystic kidney and contralateral vesicoureteral reflux is seen even more often, in 18% to 43% of infants. Because the high incidence of reflux, voiding cystourethrography usually has been considered advisable in all newborns with a multicystic kidney.

Granulomatous disease, including sarcoidosis, granulomatosis with polyangiitis, and midline granuloma, may also lead to NLD obstruction.

Additional findings that may be present in HFGS according to the latest research are:

- Limited metacarpophalangeal flexion of the thumb or limited ability to oppose the thumb and fifth finger

- Hypoplastic thenar eminences

- Medial deviation of the great toe (hallux varus), a useful diagnostic sign when present

- Small great toenail

- Fifth-finger clinodactyly, secondary to a shortened middle phalanx

- Short feet

- Altered dermatoglyphics of the hands; when present, primarily involving distal placement of the axial triradius, lack of thenar or hypothenar patterning, low arches on the thumbs, thin ulnar loops (deficiency of radial loops and whorls), and a greatly reduced ridge count on the fingers

Radiographic findings

- Hypoplasia of the distal phalanx and first metacarpal of the thumbs and great toes

- Pointed distal phalanges of the thumb

- Lack of normal tufting of the distal phalanges of the great toes

- Fusions of the cuneiform to other tarsal bones or trapezium-scaphoid fusion of the carpals

- Short calcaneus

- Occasional bony fusions of the middle and distal phalanges of the second, third, fourth, or fifth toes

- Delayed carpal or tarsal maturation

- Metacarpophalangeal profile reflecting shortening of the first metacarpal, the first and second phalanges, and the second phalanx of the second and fifth digits

Urogenital Defects

Females may have the following:

- Vesicoureteral reflux secondary to ureteric incompetence

- Ectopic ureteral orifices

- Trigonal hypoplasia

- Hypospadiac urethra

- Subsymphyseal epispadias

- Patulous urethra

- Urinary incontinence (related to structural anomalies and weakness of the bladder sphincter muscle)

- Small hymenal opening

- Various degrees of incomplete Müllerian fusion with or without two cervices or a longitudinal vaginal septum

Males may have the following:

- Retrograde ejaculation (related to structural anomalies and weakness of the bladder sphincter muscle)

Neoplasm should be considered in any patient presenting with NLD obstruction.In patients with an atypical presentation, including younger age and male gender, further workup is appropriate. Bloody punctal discharge or lacrimal sac distension above the medial canthal tendon is also highly suggestive of neoplasm.

It is a genetic developmental disorder with clinical diversity characterized by hypoparathyroidism, sensorineural deafness and renal disease. Patients usually present with hypocalcaemia, tetany, or afebrile convulsions at any age. Hearing loss is usually bilateral and may range from mild to profound impairment. Renal disease includes nephrotic syndrome, cystic kidney, renal dysplasia, hypoplasia or aplasia, pelvicalyceal deformity, vesicoureteral reflux, chronic kidney disease, hematuria, proteinuria and renal scarring.

List of common symptoms:

- "sac-like" appearance of the vocal folds

- Hoarseness and deepening of the voice

- Trouble speaking (Dysphonia)

- Reduced vocal range with diminished upper limits

- Stretching of the mucosa (Distension)

- Shortness of breath

Reinke's edema is characterized by a "sac-like" appearance of the vocal folds. The edema is a white translucent fluid that causes a bulging (distension) of the vocal cord. The most common clinical symptom associated with Reinke's edema is an abnormally low pitched voice with hoarseness. The low pitch voice is a direct result of increased fluid in the Reinke's space, which vibrates at a lower frequency than normal (females <130 Hz; males <110 Hz). Hoarseness is a common problem of many laryngeal diseases, such as laryngitis. It is described as a harsh and breathy tone of voice. Hoarseness is often seen alongside dysphonia, a condition in which the individual has difficulty speaking.

The swelling of the vocal cords and the lowering of the voice are warning signs that an individual has Reinke's edema. At the microscopic level, an examination of the vocal cords in patients with Reinke's edema will show lowered levels of collagen, elastin, and extracellular matrix proteins. These characteristics can be used to diagnose Reinke's edema. Reinke's edema is considered a benign polyp that may become precancerous if smoking is involved. An indicator of cancer is the development of leukoplakia, which manifests as white patches on the vocal folds.

Smoking, gastric reflux, and hypothyroidism are all risk factors for Reinke's edema. The symptoms of Reinke's edema are considered to be chronic symptoms because they develop gradually over time and depend on how long the individual is exposed to the risk factor. In the case of smoking, as long as the individual continues the habit of smoking, the Reinke's edema will continue to progress. This is true for other risk factors as well, such as untreated gastric reflux and overuse of the voice, which is common to professions such as singers and radio announcers.

Ask-Upmark kidneys are a cause of secondary hypertension that can be curable.

Prenatally diagnosed hydronephrosis (fluid-filled kidneys) suggest post-natal follow-up examination.

The strongest neo-natal presentation is urinary tract infection. A hydronephrotic kidney may present as a palpable abdominal mass in the newborn, and may suggest an ectopic ureter or ureterocele.

In older children, ureteral duplication may present as:

- Urinary tract infection - most commonly due to vesicoureteral reflux (flow of urine from the bladder into the ureter, rather than vice versa).

- Urinary incontinence in females occurs in cases of ectopic ureter entering the vagina, urethra or vestibule.

Posterior urethral valve (PUV) disorder is an obstructive developmental anomaly in the urethra and genitourinary system of male newborns. A posterior urethral valve is an obstructing membrane in the posterior male urethra as a result of abnormal "in utero" development. It is the most common cause of bladder outlet obstruction in male newborns. The disorder varies in degree, with mild cases presenting late due to milder symptoms. More severe cases can have renal and respiratory failure from lung underdevelopment as result of low amniotic fluid volumes, requiring intensive care and close monitoring. It occurs in about one in 8000 babies.

Prune-belly triad consists of: Cryptorchidism, abdominal wall defects and genitourinary defects:

- A partial or complete lack of abdominal wall muscles. There may be wrinkly folds of skin covering the abdomen.

- Cryptorchidism (undescended testicles) in males

- Urinary tract abnormality such as unusually large ureters, distended bladder, accumulation and backflow of urine from the bladder to the ureters and the kidneys (vesicoureteral reflux)

Other Symptoms include:

- Frequent urinary tract infections due to the inability to properly expel urine.

- Ventricular septal defect

- Malrotation of the gut

- Club foot

- Later in life, a common symptom is post-ejaculatory discomfort. Most likely a bladder spasm, it lasts about two hours.

- Musculoskeletal abnormalities include pectus excavatum, scoliosis, and congenital joint dislocations including the hip. Diagnosis of prune belly syndrome necessitates a thorough orthopaedic evaluation because of the high prevalence of associated musculoskeletal abnormalities.

It is thought to be congenital or the consequence of vesicoureteral reflux.

The classic manifestation of bladder exstrophy presents with:

- A defect in the abdominal wall occupied by both the exstrophied bladder as well as a portion of the urethra

- A flattened puborectal sling

- Separation of the pubic symphysis

- Shortening of a pubic rami

- External rotation of the pelvis.

Females frequently have a displaced and narrowed vaginal orifice, a clitoris, and divergent labia.

Most children with vesicoureteral reflux are asymptomatic. Vesicoureteral reflux may be diagnosed as a result of further evaluation of dilation of the kidney or ureters draining urine from the kidney while in utero as well as when a sibling has VUR (though routine testing in either circumstance is controversial). Reflux also increases risk of acute bladder and kidney infections, so testing for reflux may be performed after a child has one or more infections.

In infants, the signs and symptoms of a urinary tract infection may include only fever and lethargy, with poor appetite and sometimes foul-smelling urine, while older children typically present with discomfort or pain with urination and frequent urination.

Horseshoe kidney, also known as "ren arcuatus" (in Latin), renal fusion or super kidney, is a congenital disorder affecting about 1 in 600 people, more common in men.

In this disorder, the patient's kidneys fuse together to form a horseshoe-shape during development in the womb. The fused part is the isthmus of the horseshoe kidney.

Fusion abnormalities of the kidney can be categorized into two groups: horseshoe kidney and crossed fused ectopia. The 'horseshoe kidney' is the most common renal fusion anomaly.

Goldberg–Shprintzen is a condition associated with mutations in "KIAA1279" gene which encodes KIF-binding protein (KBP), a protein that may interact with microtubules and actin filament. KBP may play a key role in cytoskeleton formation and neurite growth.

Hirschsprung's disease may be part of the presentation. Individuals with the syndrome exhibit ocular (ptosis, hyperopia, or megalocornea), cardiac, urogenital (vesicoureteral reflux, multicystic renal dysplasia), and skeletal (oligodontia, scoliosis, high-arched palate) developmental abnormalities.

Reinke's edema is the swelling of the vocal cords due to fluid (edema) collected within the Reinke's space. First identified by the German anatomist Friedrich B. Reinke in 1895, the Reinke's space is a gelatinous layer of the vocal cord located underneath the outer cells of the vocal cord. When a person speaks, the Reinke's space vibrates to allow for sound to be produced (phonation). The Reinke's space is sometimes referred to as the superficial lamina propria.

Reinke's edema is characterized by the "sac-like" appearance of the fluid-filled vocal cords. The swelling of the vocal folds causes the voice to become deep and hoarse. Therefore, the major symptom of Reinke's edema is a hoarseness similar to laryngitis. The major cause associated with Reinke's edema is smoking. In fact, 97% of patient's diagnosed with Reinke's edema are habitual smokers. Other identified risk factors include overuse of the vocal cords, gastroesophageal reflux, and hypothyroidism. The disease is more often cited in women than in men, because lower voice changes are more noticeable in women.

The first cases of Reinke's edema were recorded in 1891 by M. Hajek, followed by F. Reinke in 1895. In his investigations, Reinke injected a stained glue into the superficial lamina propria (Reinke's space) to mimic edema. Reinke's edema is considered to be a benign (non-cancercous) polyp (protrusion) that represents 10% of all benign laryngeal pathologies. Treatment of Reinke’s edema starts with the elimination of associated risk factors, such as smoking, gastric reflux, and hypothyroidism. Advanced cases may undergo phonosurgery to remove the fluid from the vocal cords.

Prune belly syndrome can result in distention and enlargement of internal organs such as the bladder and intestines. Surgery is often required but will not return the organs to a normal size. Bladder reductions have shown that the bladder will again stretch to its previous size due to lack of muscle. Complications may also arise from enlarged/malformed kidneys, which may result in renal failure and the child's going on dialysis or requiring a kidney transplant. With proper treatment, however, a longer, healthier life is possible.

Megaureter is a medical anomaly whereby the ureter is abnormally . Congenital megaureter is an uncommon condition which is more common in males, may be bilateral, and is often associated with other congenital anomalies. The cause is thought to be aperistalsis of the distal ureter, leading to dilatation.

The cutoff value for megaureter is when it is wider than 6 or 7 mm.

A functional obstruction at the lower end of the ureter leads to progressive dilatation and a tendency to infection. The ureteric orifice appears normal and a ureteric catheter passes easily.

Definitive surgical treatment involves refashioning the lower end of the affected ureter so that a tunnelled reimplantation into the bladder can be done to prevent reflux.

Ectodermal dysplasia is characterized by absent sweat glands resulting in dry (hypohydrotic), often scale-like skin, sparse and usually coarse scalp hair that is often blonde, sparse eyebrows and eyelashes, and small brittle nails. In addition, abnormalities of ectodermal derivatives, neuroectodermal derivatives, and mesectodermal derivatives are often found. The ectodermal derivative abnormalities can affect the epidermis including mammary, pituitary and sweat glands, as well as hairs, dental enamel, nails, lens, and the internal ear. Neuroectodermal derivatives that can be affected include sensory placodes, cutaneous pigmental cells, and hair buds. Mesectodermal derivatives affected can include the dermis, hypodermis, dentin, head muscles and conjunctival cells, cervicofacial vascular endothelial cells, and part of the maxillofacial skeleton.

The hypohydrotic symptoms of ectodermal dysplasia described above are evidenced not only in the skin of affected individuals, but also in their phonation and voice production. Because the vocal folds may not be as hydrated as is necessary during the adduction phase of vocal fold vibration (due to lack of lubrication), a complete seal may not be accomplished between the folds and mucosal wave movement may be disrupted. This results in air escapement between the folds and the production of breathy voice, which often accompanies the skin abnormalities of ectodermal dysplasia.

The primary symptoms of contact granuloma include chronic or acute hoarseness of the voice and vocal fatigue. More severe granulomas may result in throat ache or soreness, as well as pain that lateralizes to one or both ears. Smaller granulomas may result in a tickling sensation or slight discomfort.

Signs of contact granulomas are frequent coughing and throat-clearing. Some people may also notice that their pitch range is restricted due to granuloma.

The younger the patient and the lower the grade at presentation the higher the chance of spontaneous resolution. Approximately 85% of grade I & II VUR cases will resolve spontaneously. Approximately 50% of grade III cases and a lower percentage of higher grades will also resolve spontaneously.

Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, splits (or arises twice), resulting in two ureters draining a single kidney. It is the most common renal abnormality, occurring in approximately 1% of the population. The additional ureter may result in a ureterocele, or an ectopic ureter.
