Background:
Alcoholic povidone-iodine (API) used as skin disinfection reduces the risk of postoperative infection but there is no evidence for its use on mucous membranes. We therefore conducted a tolerance study on the glans of men operated in urology.
Aim:
To confirm the safety of using API on mucous membranes.
Methods:
The impact of applying API on the glans mucosa was measured using a chromameter. Caucasian men, without any dermatological lesion of the glans, operated by endoscopic transurethral route, were included. Measurements (L*a*b*) were made preoperatively and postoperatively by an independent person. Parameters were compared using the recognized formula ΔE = √(ΔL2 + Δa2 + Δb2).
Findings:
Ninety-six patients, average age 68.9 ± 10.4 years, were included. For L*, the mean pre- and postoperative difference was +2.36 (P = 0.168). For a* and b*, the mean pre- and postoperative differences were +0.13 (P = 0.9085) and -0.12 (P = 0.17089), respectively. ΔE was equal to 13.92 ± 17.49 (non-significant difference).
Conclusion:
Our study is the first to analyse the impact of API on genital mucous membranes. In our study conditions, API had no impact on the mucous membranes, suggesting that it can be used safely.
Insights
Alcoholic povidone-iodine (API) is safe for use on genital mucous membranes. This study found no significant impact on the glans mucosa, supporting its potential use in urology procedures.
Area of Science:
- Urology
- Dermatology
- Infectious Disease Prevention
Background:
- Alcoholic povidone-iodine (API) is a recognized antiseptic for skin disinfection.
- Evidence for API's safety on mucous membranes, particularly genital mucosa, is lacking.
- Postoperative infections risk reduction necessitates evaluating antiseptic efficacy and safety on diverse anatomical sites.
Purpose of the Study:
- To assess the safety and tolerance of alcoholic povidone-iodine (API) application on the glans penis mucosa.
- To provide the first analysis of API's impact on genital mucous membranes in a clinical setting.
Main Methods:
- A tolerance study involving Caucasian men undergoing endoscopic transurethral urological surgery.
- Colorimetric measurements (L*a*b*) of the glans mucosa were taken preoperatively and postoperatively.
- Quantification of color change using the ΔE formula to determine mucosal impact.
Main Results:
- Ninety-six patients were included in the study.
- No statistically significant differences were observed in L*, a*, or b* parameters post-API application (P > 0.05).
- The overall color change (ΔE) was not significant, indicating no adverse mucosal effects.
Conclusions:
- Alcoholic povidone-iodine (API) demonstrated no significant impact on the glans penis mucosa under the study conditions.
- Findings suggest that API can be safely used for disinfection of genital mucous membranes in urological procedures.
- This study provides initial evidence supporting the safe application of API on genital mucosa.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
