We occluded the refluxing ureters using hysterosalpingogram catheters (HSG, single lumen 5.5\u2009Fr catheter with 1.5\u2009ml balloon), guidewires, and rigid cystoscope. A 6\u2009Fr dual\u2010lumen urodynamic (UD) catheter is then inserted into the bladder to perform OUUO. Bladder capacity and Compliance (<jats:italic>C<\/jats:italic>\u2009=\u2009\u2206bladder volume\/\u2206detrusor pressure) are recorded and compared with values obtained at standard UD (without ureteric occlusion).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The age range of the seven patients was 2.0\u201315.5 years. The etiology for the gross VUR were posterior urethral valve (PUV) and neuropathic. The bladder capacity and compliance finding between UD and OUUO findings were comparable in five patients. However, there was a clinically significant difference in bladder capacity (20%\u201350% decrease) and compliance (50%\u201390%) between UD and OUUO findings in two out of seven patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In the presence of gross VUR, OUUO allows for a potentially more accurate assessment of bladder capacity and compliance.
