VOIDING EFFICIENCY AFTER URETERAL REIMPLANTATION - A COMPARISON OF EXTRAVESICAL AND INTRAVESICAL TECHNIQUES

The purpose of our study was to examine postoperative changes and reco very in voiding efficiency after intravesical and extravesical uretera l reimplantation, Retrospective review was performed of 188 cases, Inc lusion criteria were the presence of primary vesicoureteral reflux and the absence of previous lower urinary tract surgery. Voiding efficien cy after ureteral reimplantation was assessed based on post-void resid ual volume measurements. It was found that postoperative voiding effic iency of patients in the extravesical unilateral group was similar to that in the intravesical group, while the extravesical bilateral group had a statistically significantly higher proportion of patients with transient voiding inefficiency. A statistically higher proportion of t hose in the extravesical bilateral group also required some form of ur inary catheter drainage for a longer period. However, on more prolonge d followup all evaluable patients in the 3 groups fully regained voidi ng efficiency.
