We aim to report long-term functional and symptomatic outcomes following PED and perform analysis to predict outcomes. MATERIAL AND METHODS We performed a retrospective review of all children with DSU between 2004–2014, with minimum 2.5 years follow up. We perform ‘selective’ PED and follow up surgery based on symptomology. Demographic and diagnostic variables were collected including: antenatal diagnosis, age at pres- entation and surgery, weight, comorbidity, VUR status, bladder dysfunction, intra/extravesicular, hydroureteronephrosis and upper pole function. Primary outcomes were: successful PED, worsen- ing moiety function, further surgery indicated (FSI), voiding dysfunction (VD) and treatment free status (TFS). Demographic and diagnostic variables were compared with primary outcomes to test association (chi 2 and spearman rho correlation). RESULTS We identified 41 cases of DSU, with a 77 % successful PED decompression rate. At mean follow up 6 years (range 2.5–10.2): 17.1 % showed worsened renal function, 63.4 % required FSI and 36.6 % had some VD but overall 61.5 % were treatment free. We compared the data before and after 2011, when routine fetal anomaly scanning was introduced, and showed association only with improved TFS (42 % vs 80 % p=0.02) at 8.5 and 4.1 years follow up respectively. Presentation in urosepsis was associated with later VD, female sex with FSI (OR 13.7 p=0.001) and lower TFS, and earlier age of intervention with VD and lower TFS. CONCLUSIONS DUS is associated with long-term ongoing treatment in 38.5 % but this improves with time. Predictors of symptomology include female sex, presenting in urosepsis and earlier age of surgical intervention.
