Background: Evaluation of circumcision bleeding cannot depend on the visual change in the diaper. Diapers have different product features and absorbency capacities. The apparent changes in the diapers may vary according to their absorbent capacity and may not be in parallel with the amount of bleeding. Before significant visual difference occurs, the patient's hemodynamics may be impaired. Aim: Aim of the study is to evaluate better circumcision bleeding. Patients and Methods: Patients were divided into groups according to 12 different brand diapers of the same size, containing super-absorbent material. The study started by 15/01/2022, and finished by end of 01/03/2022. Diapers with concealed brands were soaked with blood with equal hematocrit value in 100 ml with increments of 5 ml. 252 images were obtained by taking 21 images of each diaper with the same method. The diapers were evaluated colorimetrically, and numerical values were obtained showing the color differences in red, green, and blue and saturation and lightness. Working groups were formed according to 12 different brands of diapers of the same size, containing super-absorbent material. Standard statistical tests were performed using obtained values. Result: Dry diapers had different weights, volumes, and specific gravities; the diapers with the lowest unit weight were ranked ninth in terms of volume; the diapers with the highest specific gravity were ranked third in terms of thinness. There were significant differences in the blood on the diaper, and significant differences between some groups (p < 0.005); on the other hand, there was not any difference between some other groups (p > 0.05). There was a significant relationship in terms of Analysis of Variance (ANOVA) (P < 0.05 and P < 0.01). Visual graphic examination showed that linear but non-parallel color changes occurred. As the blood load increased, the visual and statistical differences between the diapers became more pronounced, and the curves diverged. Conclusion: Visual evaluation of the color change of the diapers may not give accurate results for bleeding follow-up. If necessary to use diapers after circumcision, it is more appropriate to prefer those with low absorbency capacity. Using fabric or cotton products in cases with bleeding risk may be recommended. If bleeding is suspected, hemogram control is the most appropriate option. Diaper manufacturers should warn consumers of the risk. In conclusion, we should be on the safe side for mortality and morbidity.
