Abstract
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 <150ml.

  • 2.

    Neurological disorders.

  • 3.

    History of urogenital surgery.

Bladder outlet obstruction was defined as follows: Postvoid residue (PVR) >20%; peak flow (Qmax) <15ml/sec; detrusor pressure at maximum flow (PdetQmax) >25cm 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 <15ml/sec was seen in 15.6% and 27.8% of Group A and Group B patients respectively (p=0.03). A PdetQmax >25cm 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.

Resumen
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 <150ml.

  • 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) <15ml/s; y presión del detrusor en el flujo máximo (PDetQmáx) >25cmH2O.

Resultados

el grupo A incluyó al 64,0% de las pacientes y el grupo B al 36% restante. Se apreció volumen residual postmiccional (VRP) patológico en el 26,6% 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 >25cmH2O 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.
