Measurement of Postvoid Residual Volume in Advanced Pelvic Organ Prolapse Classified by Pelvic Organ Prolapse Quantification[POP-Q]


1] to introduce pelvic organ prolapse quantification[POP-Q] exam. 2] to evaluate the relationship between postvoid residual volume and degree of pelvic organ prolapse. 3] to evaluate the relationship between age, parity, stress incontinence and urge incontinence with advanced pelvic organ prolapse. METHOD:The sample for this study consisted total of 110 patients who did not complain of urinary symptoms. They were evaluated in the period between Aug. 1997 and Aug. 1998 at Pohang Hospital. The enrolled patients were examed by POP-Q and then classified a control group[n=36] as normal to mild pelvic organ prolapse[stageO,I] and a study group[n=24] suffered from advanced pelvic organ prolapse[stageIII,IV]. The postvoid residual volume was measured by urinary catheterization. The age, parity, stress and urge incontinence symptoms were recorded by a history taking session.
1]High postvoid residual volume[70.20+/-46.23cc] was obtained in advanced pelvic organ prolapse which is classified as stage III or IV compared to normal or mild pelvic organ prolapse[8.83+/-11.00cc]displayed in the control group. 2]A higher age and parity was directly related to advanced pelvic organ prolapse compared to normal or mild pelvic organ prolapse. 3]The incidence of urge incontinence and mixed incontinence was also directly related with advanced pelvic organ prolapse compare to normal or mild pelvic organ prolapse.
The patients who have advanced pelvic organ prolapse with high postvoid residual volume should be carefully evaluate before pelvic reconstructive or antiincontinence surgery. This study suggest that advanced pelvic organ prolapse could lead to further functional loss of upper urinary tract.
