ESPU Congress 2018 - Abstract Book

58 29 th CONGRESS OF THE ESPU MATERIAL AND METHODS 334 renal units with regular clinical follow-up who were treated due to VUR(vesicoureteral reflux) between years 2009–2017 were retrospectively reviewed. Preoperative clinical parameters as grade and laterality of reflux, presence of renal scar, initial and follow-up treatments, findings of medical treatment and surgical procedures were analysed by grouping patients according to initial treatment year,as before and after 2013. Clinical outcomes of surgical and medical treatments were compared in both groups; before and after 2013. Clinical failure was identified as; performing surgery for nonresponsive cases to medication, symptomatic urinary tract infection after surgery and new renal scar in postoperative DMSA. RESULTS Mean age and follow-up duration were 71,4(6–216)months and 47(4–141)months, respectively. We determined that VUR risk grouping does not change clinical success significantly in all risk groups (table) VUR RISK GROUP INITIAL TREATMENT YEAR TREATMENT SUCCESS MEDICAL(%) SURGERY(%) LOW RISK BEFORE 2013 SUCCESSFULL 2(13) 38(93) UNSUCCESSFULL 13(87) 3(7) AFTER 2013 SUCCESSFULL 0 1(25) UNSUCCESSFULL 4(100) 3(75) p VALUE 0.4 <0.001 MODERATE RISK BEFORE 2013 SUCCESSFULL 5(11) 95(93) UNSUCCESSFULL 39(89) 7(7) AFTER 2013 SUCCESSFULL 5(25) 11(78) UNSUCCESSFULL 15(75) 3(22) p VALUE 0.164 0.069 HIGH RISK BEFORE 2013 SUCCESSFULL 1(5) 32(58) UNSUCCESSFULL 19(95) 23(42) AFTER 2013 SUCCESSFULL 0 4(67) UNSUCCESSFULL 9(100) 2(33) p VALUE 0.495 0.688 TOTAL 112(34) 222(66) CONCLUSIONS Despite the fact that EAU/ESPU VUR risk classification changed our current practice in terms of initial treatment method, this different approach did not seem to affect early clinical success positively. There is still an absolute need for studies with larger sample size and long-term follow-up to reach more reliable results. 09:04–09:19 Discussion
