CAUSES, INCIDENCE, AND RISK FACTORS Many authors have stated that meatal stenosis in males is caused by , it can rub against urine soaked diapers resulting in inflammation and mechanical trauma. Eventually, the delicate Epithelial lining of the outer urethra is lost, leaving only a pinpoint hole at the tip of the glans. Meatal stenosis may also be caused by damage to the Frenular artery during circumcision. {Link without Title} [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=16429216&query_hl=3&itool=pubmed_docsum Meatal stenosis may also be associated with .[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12175386&query_hl=29&itool=pubmed_docsum] In females, this condition is a Congenital (present from Birth ) abnormality which can cause Urinary Tract Infection s and bed-wetting ( Enuresis ). SYMPTOMS
SIGNS AND TESTS In boys, history and Physical Exam is adequate to make the Diagnosis . In girls, VCUG ( Voiding Cystourethrogram ) is usually diagnostic. Other tests may include:
TREATMENT In females, meatal stenosis can usually be treated in the physician's office using Local Anesthesia to numb the area and dilating (widening) the urethral opening with special instruments. In boys, it is treated by a second surgical procedure called Meatotomy in which the meatus is crushed for 60 seconds with a straight mosquito hemostat and then divided with fine-tipped scissors. Recently, home-dilation has been shown to be a successful treatment for most boys. {Link without Title} PROGNOSIS Most people can expect normal urination after treatment. COMPLICATIONS Persistent urinary problems including abnormal stream, Painful urination, frequent urination, urinary incontinence, blood in the urine, and increased susceptibility to urinary tract infections can be complications. PREVENTION "In a recently circumcised male infant, try to maintain a clean, dry diaper and avoid any exposure of the newly circumcized penis to irrititants (sic)." {Link without Title} Meir and Livne suggest that use of a broad spectrum antibiotic after hypospadias repair will "probably reduce meatal stenosis [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15118434&query_hl=21&itool=pubmed_docsum while Jayanthi recommends the use of a modified Snodgrass hypospadias repair. Viville states that "prevention is based essentially upon more caution in the use of indwelling urethral catheters."[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=7310161&query_hl=21&itool=pubmed_docsum SOURCE
