Post-void residual volume (PVR) is the urine volume left in bladder at the completion of micturition. It is a key marker for the efficacy of bladder emptying. PVR measurement is essential, particularly in women with the symptoms of pelvic floor dysfunction, including those with lower urinary tract and pelvic organ prolapse symptoms. Patients attending with genitourinary prolapse were explained about the nature of the study and written and informed consent was obtained. Detailed history, general physical examination was done as per predesigned and pretested proforma. 47 patients complained about 'has to reduce prolapse to void' and it was significantly associated with the degree of prolapse. P value was <0.0001. Out of 33 patients with PVR >50 ml, only 1 patient had POPQ stage 2 prolapse, 14 patients had POPQ stage 3 prolapse and 18 patients had POPQ stage 4 prolapse. P value was 0.024.The number of patients with PVR >50 m l had increased with increase in the grade of Baden Walker prolapse, Out of six patients of procedentia, five patients had raised PVR. P value is 0.005.In this study, increasing degree of prolapse by both the classifications has shown a statistically significant relation with Raised PVR.
