Influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions.

CONTEXT: The correlation between vaginal delivery, age and pelvic floor dysfunctions involving obstructed defecation is still a matter of controversy. OBJECTIVES: To determine the influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions in women with obstructed defecation syndrome. METHODS: Four hundred sixty-nine females with obstructed defecation syndrome were retrospectively evaluated using dynamic 3D ultrasonography to quantify posterior pelvic floor dysfunctions (rectocele grade II or III, rectal intussusception, paradoxical contraction/non-relaxation of the puborectalis and entero/ sigmoidocele grade III). In addition, sphincter damage was evaluated. Patients were grouped according to age (≤50y x >50y) and stratified by mode of delivery and parity: group I (≤50y): 218 patients, 75 nulliparous, 64 vaginal delivery and 79 only cesarean section and group II (>50y): 251 patients, 60 nulliparous, 148 vaginal delivery and 43 only caesarean section. Additionally, patients were stratified by number of vaginal deliveries: 0 - nulliparous (n = 135), 1 - vaginal (n = 46), >1 - vaginal (n = 166). RESULTS: Rectocele grade II or III, intussusception, rectocele + intussusception and sphincter damage were more prevalent in Group II (P = 0.0432; P = 0.0028; P = 0.0178; P = 0.0001). The stratified groups (nulliparous, vaginal delivery and cesarean) did not differ significantly with regard to rectocele, intussusception or anismus in each age group. Entero/sigmoidocele was more prevalent in the vaginal group <50y and in the nulliparous and vaginal groups >50y. No correlation was found between rectocele and the number of vaginal deliveries. CONCLUSION: Higher age (>50 years) was shown to influence the prevalence of significant rectocele, intussusception and sphincter damage in women. However, delivery mode and parity were not correlated with the prevalence of rectocele, intussusception and anismus in women with obstructed defecation.

CONTEXTO: A correlação entre parto vaginal, idade e disfunções do assoalho pélvico em pacientes com evacuação obstruída permanece ainda controverso. OBJETIVO: Determinar a influência da idade, tipo de parto e paridade na prevalência de disfunções do assoalho pélvico posterior em mulheres com evacuação obstruída. MÉTODOS: Quatrocentas e sessenta e nove mulheres com evacuação obstruída foram avaliadas, retrospectivamente, utilizando ultrassonografia tridimensional dinâmica para quantificar disfunções do assoalho pélvico posterior (retocele grau II ou III, intussuscepção retal, anismus e entero/sigmoidocele grau III) e presença de lesão esfincteriana. As pacientes foram agrupadas de acordo com a idade (<50 anos e >50 anos) e estratificadas por tipo de parto e paridade em grupo I (<50 anos): incluindo 218 pacientes (75 nulíparas, 64 com partos vaginais e 79 apenas com operações cesarianas) e grupo II (>50 anos): incluindo 251 pacientes (60 nulíparas, 148 com partos vaginais e 43 apenas com cesarianas). Além disso, as pacientes foram estratificadas por número de partos vaginais em nulíparas (n = 135), com um parto vaginal (n = 46) e com mais de um parto vaginal (n = 166). RESULTADOS: Retocele, intussuscepção, associação de intussuscepção e retocele e lesão esfinceriana foram mais prevalentes no grupo II (P = 0,0432, P = 0,0028, P = 0,0178, P = 0,0001). Não houve diferença significante na prevalência de retocele, intussuscepção ou anismus em relação ao tipo de parto e paridade, em cada faixa etária. Êntero/sigmoidocele foi mais prevalente em pacientes com parto vaginal no grupo I e em nulíparas e com parto vaginal no grupo II. Nenhuma correlação foi encontrada entre prevalência de retocele e número de partos vaginais. CONCLUSÃO: A idade superior a 50 anos está associada a maior prevalência de retocele, intussuscepção e lesão esfincteriana, no entanto, a paridade e o tipo de parto não se correlacionam com a prevalência de intussuscepção, retocele e anismus em mulheres com evacuação obstruída.
