Postoperative partial or complete urinary retention may develop after radical gynecologic interventions. Dysfunction of the urinary bladder may cause urinary retention and increases the incidence of postoperative urinary tract infection. Sonographic assessment of the residual volume of the urinary bladder is an exact, non-invasive, and reproducible method. The authors report on a six-month prospective study of patients with cervical cancer who have undergone radical abdominal hysterectomy (n=17) at the Department of Obstetrics and Gynecology of the University of Pecs and estimated the amount of postoperative residual urine after voiding with two different methods of three-dimensional sonographic volumetry (VOCAL and XI VOCAL) (n=35) and with exact measurement of the retained urine by the catheter. In addition, the authors tested and compared the feasibility and the accuracy of the two different sonographic methods in an in vivo organ-volume estimation and validated the XI VOCAL method in an in-vivo setting. Three-dimensional sonographic volume determination of postoperative urinary retention with the application of the VOCAL- and XI VOCAL- softwares correlated significantly with the actual amount of the retained urine measured by catheterization. If the amount of the retained urine did not exceed 350 mls, the accuracy of the XI VOCAL method was superior to that of the VOCAL. In case of postoperative urinary retention following radical hysterectomy both non-invasive three-dimensional sonographic methods are appropriate for the correct volume determination of the retained urine. With their clinical application we may decrease the number of unnecessary urinary bladder catheterization, reduce the incidence of iatrogenic urinary tract infection, and thus permit a better postoperative comfort for patients.
