Assessment of Platelet Rich Plasma Injection in Managing Female Patients Complaining of Mixed Urinary Incontinence (PRP)

All patients will be subjected to:

• An informed consent will be taken from every patient.
• Complete history taking:

• Personal history
• Any complaint.
• Past medical and past surgical history.
• Family history.
• Severity of incontinence by International consultation on incontinence questionnaire- short form (ICIQ-SF), OAB symptom score ,Cough stress test

*Complete physical examination.

• General examination: Vital signs (Blood pressure, Temperature, Heart rate, Respiratory rate).
• neurological examination: gait, perineal sensation, bulbocavernous reflex, cognitive status
• abdominal examination : distended bladder, masses , hernia, DRE
• Pelvic examination: vaginal atrophy, skin excoriation, vault examination, organ prolapse, pelvic floor muscle strength , cough test, Q tip test, Marshall test
• urodynamics done for documentation of detrusor overactivity before and after PRP installation after 3rd instillation and 4 m after last instillation

• patient is placed in the dorsal lithotomy position
• PRP is obtained from a sample of patients' blood drawn at the time of treatment
• A 30 cc venous blood draw will yield 3-5 cc of PRP
• The blood draw occurs with the addition of an anticoagulant, such as citrate dextrose A( .5 ml)to prevent platelet activation prior to its use
• in room temp 21-24 to avoid activation of platelet
• a specialized 'table top cold centrifuge' device to centrifugate the sample
• After centrifugation, each vial was confirmed to contain three layers from top to bottom, namely, the platelet pellet, gel, and red blood cells. The platelet pellet was remixed with the supernatant by inverting the tubes gently 5-10 times.
• A-PRP was injected into the anterior vaginal mucosa around the mid-urethral area, which was approximately 1 cm below the urethral meatus and had a depth of about 1.5 cm; 2 mL were injected underneath the mid-urethral area and 1.5 mL was injected on either side of the urethra
• 10ml PRP used to instill intravesical for urgency urinary incontinence by urethral catheter
• patient received four injections of PRP at monthly intervals
• follow up done after 3rd instillation and 4 months after finishing injections
• follow up done by subjective symptoms as previous scoring system and objective by Urodynamics
