RESUMO
INTRODUCTION: Controversy exists as to whether cystocele has a causative role in bladder outlet obstruction (BOO). OBJECTIVE: To assess the relationship between cystocele and bladder outlet obstruction. MATERIALS AND METHODS: Two hundred women undergoing a urodynamic study from December 2007 to December 2008 were retrospectively assessed. Patients were divided into two groups: Group A: Patients with no cystocele (Grade 0) and Grade I cystocele Group B: Patients with Grade II-IV cystocele. EXCLUSION CRITERIA: 1. Absence of flowmetry or voided volume < 150 ml. 2. Neurological disorders. 3. History of urogenital surgery. Bladder outlet obstruction was defined as follows: Postvoid residue (PVR) > 20%; peak flow (Qmax) < 15 ml/sec; detrusor pressure at maximum flow (PdetQmax) > 25 cm H2O. RESULTS: Group A included 64% of patients, and Group B the remaining 36%. A pathological PVR > 20% was found in 26.6% and 40.3% of patients in Group A and Group B respectively (p=0.04). A Qmax < 15 mL/sec was seen in 15.6% and 27.8% of Group A and Group B patients respectively (p=0.03). A PdetQmax > 25 cm H2O was found in 26.3% and 47.8% of Group A and Group B patients respectively (p=0.01). CONCLUSIONS: A statistically significant association exists between cystocele and bladder outlet obstruction.

Introducción: existen controversias con respecto a si la presencia de cistocele, y el grado de este, es un factor de obstrucción del tracto urinario inferior (TUI).Objetivos: valorar la relación entre el cistocele y la obstrucción infravesical. Material y métodos: evaluamos retrospectivamente a 200 mujeres sometidas a estudio urodinámico, entre diciembre de 2007 y diciembre de 2008.Se clasificó a las pacientes en 2 grupos: Grupo A: ausencia de cistocele (grado 0) y grado I. Grupo B: cistocele grado II-IV. Criterios de exclusión: 1. Ausencia de flujometría libre o volumen vaciado < 150 ml. 2. Existencia de patología neurológica. 3. Antecedentes de cirugía urogenital. Definimos obstrucción del TUI según los siguientes parámetros: volumen residual postmiccional (VRP) > 20%; flujo máximo (Qmáx) < 15 ml/s; y presión del detrusor en el flujo máximo (PDetQmáx) > 25 cmH2O. Resultados: el grupo A incluyó al 64,0% de las pacientes y el grupo B al 36% restante. Seapreció volumen residual postmiccional (VRP) patológico en el 266% en el grupo A y en el 40,3% en el grupo B (p= 0,04); Qmáx < 15ml/s en 15,6% en el grupo A y en el 27,8% en el grupo B (p= 0,03); PDetQmáx > 25 cmH2O en el 26,3% en el grupo A y en el 47,8% en el grupo B (p= 0,01). Conclusiones: existe una asociación estadísticamente significativa entre el cistocele y parámetros de obstrucción infravesical (AU)
