    Abstract:
    OBJECTIVE: To compare the barbed polyglyconate suture (BPS) with 2 commonly used conventional sutures, this prospective randomized trial was designed. The sutures applied in the urinary collecting system, in terms of long-term histopathologic and macroscopic suture material features. MATERIALS AND METHODS: Eight female and 6 male New Zealand rabbits were included in the study. Each animal served as its own control and was subjected to cystotomy. Watertight running cystorrhaphies were performed using 3 different sutures in a randomized fashion, namely Monocryl, Vicryl, and V-Loc 90. Seven animals were sacrificed after the third and 7 after the sixth week. Macroscopic and histopathologic examinations were performed. Tissue reaction, like inflammation and fibrosis, around the sutures were evaluated. Friedman and Wilcoxon signed ranks test was used for the statistical analysis. RESULTS: The BPS demonstrated no adhesion. However, in the six-week group, stone formation was recorded on 4 BPS and 1 Vicryl thread, a difference being statistically significant (P = .039). Additionally, in the third- and in the sixth-week group, 1 (P = .368) and 3 (P = .050) BPS threads migrated, respectively. The histopathologic analysis revealed less inflammation and fibrosis associated with the BPS thread in both the third and the sixth-week groups (P = .010 and P = .002, respectively). CONCLUSION: The BPS appears to be superior to conventional sutures in terms of local inflammation and fibrosis. However, suture migration and stone formation following collecting system closure could be potential predicaments.
