Brief summary: This study is necessary in order to provide proof the effectiveness of Chlorhexidine gluconate and its safety.

Detailed description: It is well known from the literature that the use of Povidone-iodone based solution for vaginal preparation before surgery is fraught with side effects and sensitivity, and often does not provide sufficient eradication of colonies of pathogens from the operation field.

It is also known that Chlorhexidine gluconate in low concentration provides a better result and does not cause side effects more than Povidone-iodone, but the chlorhexidine is still not approved for washing the mucous membranes. This study is necessary in order to provide proof of its effectiveness and safety.

Eligibility criteria: Inclusion Criteria:

1. Patients over the age of 18
2. Candidates for surgery (TOT- Trans Obturator Tape, cystoscopy, the introduction / removal of the stent the ureter, ureteroscopy), local or general anesthesia.

Exclusion Criteria:

1. A pregnant woman or post-partum.
2. A woman with known sensitivity to iodine, povidon or chlorhexidine.
3. Previous pelvic surgeries within three months from the surgery planned.
4. Patients taking antibiotics within one month from the surgery planned.
5. Immunological failure patients.
6. Patient unwilling to participate in the study.
7. Patients who require the appointment of a guardian condition
8. Women assigned to undergo a regular cystoscopy (no further action).

Primary outcomes:
measure: Changing in the number of colonies that grew at every stage
timeFrame: Before the washing, 10 minutes after washing, 30 minutes after washing.
Secondary outcomes:
measure: Signs of local irritation mucosa after each bathing preparations by looking at the mucosa, at the end of the clinical assessment.
timeFrame: 30 minutes after washing.
measure: The appearance of signs of systemic allergic reactions after each bathing by looking at the mucosa, at the end of the clinical assessment.
timeFrame: Before the washing, 10 minutes after washing, 30 minutes after washing.
