\n A estenose meatal \u00e9 uma condi\u00e7\u00e3o urol\u00f3gica caracterizada por um estreitamento anormal da abertura uretral (meato) na ponta do p\u00eanis, que restringe o fluxo de urina.1<\/sup> Essa anomalia estrutural pode ser cong\u00eanita (presente ao nascimento), mas \u00e9 mais comumente adquirida, sobretudo como complica\u00e7\u00e3o ap\u00f3s a circuncis\u00e3o.2<\/sup> O termo \"estenose\" refere-se ao estreitamento patol\u00f3gico de uma passagem do corpo, neste caso acometendo o meato uretral externo.3<\/sup> Esse estreitamento aumenta a resist\u00eancia ao fluxo de sa\u00edda da urina, levando a altera\u00e7\u00f5es na din\u00e2mica do jato urin\u00e1rio e aos sintomas associados.

\n A estenose meatal \u00e9 encontrada principalmente na pr\u00e1tica da urologia pedi\u00e1trica, embora possa acometer pessoas do sexo masculino de qualquer idade. A condi\u00e7\u00e3o \u00e9 diagnosticada com mais frequ\u00eancia em indiv\u00edduos circuncidados, e estudos indicam que \u00e9 rara em indiv\u00edduos n\u00e3o circuncidados.1<\/sup> Os crit\u00e9rios de sele\u00e7\u00e3o de pacientes para interven\u00e7\u00e3o geralmente se baseiam na presen\u00e7a de sintomas, e n\u00e3o apenas nos achados anat\u00f4micos, pois existem varia\u00e7\u00f5es naturais na largura do meato.2<\/sup>\n <\/p>\n

\n A etiologia mais comum em pacientes pedi\u00e1tricos \u00e9 a inflama\u00e7\u00e3o p\u00f3s-circuncis\u00e3o, na qual a glande e o meato rec\u00e9m-expostos ficam irritados pelo contato com a fralda ou pela exposi\u00e7\u00e3o \u00e0 am\u00f4nia e aos cristais de \u00e1cido \u00farico presentes na urina.3<\/sup> Em adultos, a estenose meatal pode resultar de instrumenta\u00e7\u00e3o uretral, cateterismo de longa dura\u00e7\u00e3o, l\u00edquen escleroso ou outras condi\u00e7\u00f5es inflamat\u00f3rias que afetam a uretra distal.4<\/sup>\n <\/p>\n

\n O quadro cl\u00ednico normalmente inclui jato urin\u00e1rio desviado para cima e dif\u00edcil de direcionar, dis\u00faria (mic\u00e7\u00e3o dolorosa), aumento da frequ\u00eancia urin\u00e1ria, urg\u00eancia e, ocasionalmente, hemat\u00faria terminal (sangue no final da mic\u00e7\u00e3o).5<\/sup> O exame f\u00edsico revela um orif\u00edcio meatal puntiforme ou estreitado, e a observa\u00e7\u00e3o da mic\u00e7\u00e3o frequentemente mostra um jato fino, \u00e0s vezes forte, com esvaziamento vesical incompleto.6<\/sup>\n <\/p>\n

\n A avalia\u00e7\u00e3o diagn\u00f3stica \u00e9 principalmente cl\u00ednica, embora o exame de urina possa ser realizado para descartar infec\u00e7\u00e3o. Nos casos de apresenta\u00e7\u00e3o mais complexa, exames adicionais, como urofluxometria ou ultrassonografia, podem estar indicados para avaliar complica\u00e7\u00f5es do trato urin\u00e1rio superior.2<\/sup>\n <\/p>\n

\n As op\u00e7\u00f5es de tratamento incluem:\n <\/p>\n

\n 1. Meatotomia\/meatoplastia cir\u00fargica: o principal pilar do tratamento, que consiste na amplia\u00e7\u00e3o cir\u00fargica do orif\u00edcio meatal. Esse procedimento ambulatorial apresenta alta taxa de sucesso e baixa recorr\u00eancia.3<\/sup>\n <\/p>\n

\n 2. Corticoterapia t\u00f3pica: nos casos mais leves, a aplica\u00e7\u00e3o de creme de corticosteroide no meato duas vezes ao dia por at\u00e9 tr\u00eas meses pode proporcionar al\u00edvio suficiente.4<\/sup>\n <\/p>\n

\n 3. Dilata\u00e7\u00e3o meatal: utilizada com menos frequ\u00eancia devido ao risco de cicatriza\u00e7\u00e3o e \u00e0s menores taxas de sucesso em compara\u00e7\u00e3o com as abordagens cir\u00fargicas.5<\/sup>\n <\/p>\n

\n Os resultados esperados ap\u00f3s a interven\u00e7\u00e3o adequada s\u00e3o excelentes, e a maioria dos pacientes apresenta resolu\u00e7\u00e3o completa dos sintomas e fun\u00e7\u00e3o urin\u00e1ria normal.6<\/sup> Sem tratamento, as poss\u00edveis complica\u00e7\u00f5es incluem infec\u00e7\u00f5es do trato urin\u00e1rio, esvaziamento vesical incompleto e, raramente, les\u00e3o do trato urin\u00e1rio superior decorrente de obstru\u00e7\u00e3o cr\u00f4nica.1<\/sup>\n <\/p>","gt-related-evidence":null,"gt-featured":true,"gt-ai-referenced":false,"gt-view-count":106},"yoast_head":"\nEstenose Meatal: Estreitamento do Meato Urin\u00e1rio | Rigicon<\/title>\n<meta name=\"description\" content=\"Saiba sobre estenose meatal, estreitamento da abertura uretral externa.
