It seems that this technique offers a better outcome because it might be is associated with less mucus production avoiding its associated complications. The aim of this study was to compare mucus production after enterocistoplasty with or without removing mucosa in two groups of patients. MATERIAL AND METHODS With ethical committee approval a comparative prospective study of mucus production in two different groups of patients following an enterocistoplasty was done. All patients had more than 5 years follow-up. Patients presenting with recurrent urinary tract infection were excluded. Group "A" included patients with ileocistoplasty and non-demucosalized colon and group "B" patients with demucosalized sigmoid. First morning urine was taken through urethral catheterization or through urinary continent derivation. In a wintrobe tube, 10 cc of urine were centrifuged at 2500 rpm for 10 minutes. A blinded microscopic analysis with mucus quantification and statistic analysis between both groups was made. RESULTS Seventy patients were included in this study (52 Group A and 18 Group B). Mucus amount for Group B was statistically lower (p=0.0061; CI 95 %). It is also highlighted, that all patients treated in Group A need daily bladder washout compared with patients from Group B whom did not performed bladder washouts. CONCLUSIONS A lower mucus amount and production in patients with demucosalized sigmoid enterocistoplasty was confirmed. This technique might offer a better long-term outcome, reducing mucus-related complications; i.e. stones formation and UTI.
