The purpose is to evaluate the factors affecting LUTS in adults treated for PUV. MATERIAL AND METHODS LUTS were evaluated with DAN-PSS questionnaire in 78 adult patients treated for PUV in child- hood. Symptom scores (SS) were compared with patient characteristics and types of treatment. RESULTS Patient median age was at treatment 0.6 (range 0–11.5) years and at investigation 35 (range 16–57) years. Median total-SS was 1 (IQR 0–5, range 0–18). Patient age at investigation and total-SS were correlated (R=0.220, p=0.032), but primary creatinine level and total-SS were not (R=0.260, p= 0.081). 18 patients who had temporary ring type ureterocutaneostoma and 10 pa- tients who had undergone kidney transplantation had similar total-SSs as those without stoma or kidney transplantation (p=0.487 and p=0.944 respectively). Median age for achieving both day and night continence was 6.3 years. Total-SS and the age becoming continent were not correlated (p=0.365 and p=0.679 respectively). In the age group 39-year or more, 19 patients who had had bladder neck incision (BNI), storage-SS was higher than in the remainder 15 patients (1 (IQR 0–5) vs. 0 (IQR 0–0), p=0.030. However, the age at diagnosis was younger among those who had undergone BNI (0.8 (IQR 0.5–4.5) years vs. 5.9 (IQR 4.3–9.1) years, p=0.003). CONCLUSIONS LUTS causing bother are rare in adults treated for PUV in childhood. Reasons for LUTS are appar- ently multifactorial and single reasons are difficult to indicate. 16:00–16:03 S19-3 (PP) LONG-TERM FOLLOW-UP OF POSTERIOR URETHRAL VALVES AND RISK FACTORS FOR RENAL FAILURE Anna BUJONS, Arnau SERRA and Erika LLORENS DE KNECHT Fundació Puigvert, Paediatric Urology, Barcelona, SPAIN PURPOSE Posterior urethral valves (PUV) are the first congenital cause of low urinary tract obstruction and urological renal failure. Both the associated congenital renal dysplasia and subsequent urodynamic alterations can condition its evolution. The objective of this study is to describe the long-term evolu- tion of our series and to determine possible prognostic factors.
