Abstract
Background: Bladder neck reconstruction in children with bladder exstrophy carries a risk of early wound complications; an autologous platelet-rich fibrin (PRF) membrane may provide an additional biological covering of the suture line.
Objective: To evaluate the efficacy of additional coverage of the bladder neck reconstruction zone with an autologous PRF membrane for preventing early wound complications.
Materials and Methods: We followed 86 children with bladder exstrophy operated on at the National Children's Medical Center. A PRF membrane prepared from 5-10 mL of the child's own blood (centrifugation for 13-15 min at 3000 rpm) was placed over the bladder neck suture line in 15 children; 69 children were operated on without this coverage. Fisher's exact test, Spearman correlation, logistic regression, and ROC analysis were used.
Results: Complications occurred in 13.3% of children with PRF coverage and 43.5% without it (p = 0.039; OR 0.20; 95% CI 0.06-1.00). The membrane was the only significant protective factor (rho = -0.24; p = 0.029); pubic diastasis, bladder volume, and age showed no predictive value (AUC <= 0.56). The model reached an AUC of 0.66.
Conclusions: PRF membrane coverage significantly reduces early wound complications. The method is simple, autologous, inexpensive, and reproducible.
