Abstract

(Background) The objective of this report is to evaluate the upper urinary tract changes of the patients with spina bifida who have been followed up for more than 10 years.<br>(Methods) We analyzed 228 patients (97 males and 131 females) of spina bifida. Mean patient age was 18.7 years (10 to 51 years) and follow up period ranged from 10 to 27 years (mean 13.4 years). Upper urinary tract deterioration (Hydroureter and/or hydronephrosis), vesicoureteral reflux (VUR) and bladder deformity were investigated by excretory urography and voiding cystourethrography. We compared these 3 parameters in the initial and final examinations.<br>(Results) In the initial examinations, upper urinary tract deterioration, VUR and bladder deformity were observed in 32.9%, 33.3% and 40.0%, respectively. During the follow up period, upper urinary tract was improved in 47.3% and VUR in 80.0%. Bladder deformity was disappeared in 14.4%. On the other hand, upper urinary tract was deteriorated in 9.3%. VUR and bladder deformity was newly developed or progressed in 8.0% and 29.3%, respectively. Finally, upper urinary tract deterioration, VUR and bladder deformity were observed in 31.3%, 18.2% and 52.0%, respectively.<br>(Conclusion) These results revealed that upper urinary tract and VUR were relatively controlled, however, bladder deformity was increased in its frequency. To prevent upper utrinary tract deterioration, further analysis of sequential changes of urinary tract conditions shouled be demanded.
