入选标准

  • Patients were eligible for inclusion if they met the following criteria:
  • Adult patients (≥18 years)
  • Diagnosed with anterior urethral stricture requiring substitution urethroplasty
  • Planned use of buccal mucosal graft for urethral reconstruction
  • Ability to provide informed consent and comply with follow-up protocol

  • Known allergy to biological graft materials

研究组 & 干预措施

Amniotic membrane coverage group

Active Comparator

Application of amniotic membrane in buccal graft site after harvesting buccal mucosa graft for using it in uretheroplasty

结局指标

主要结局

Postoperative donor-site epithelialization of the buccal donor site using Oral Mucosa Rating Scale (OMRS)

时间窗: from the first day post op to 12 weeks

Oral Mucosa Rating Scale (OMRS): visual assessment of oral mucosa erythema, ulceration granulation, suppuration, and edema. * Erythema (Redness): from (0) normal to (3) severe * Ulceration: from (0) normal to (3) severe * Granulation Tissue (Healing/Chronic Inflammation): from (0) normal to (3) severe * Suppuration (Pus/Infection): from (0) normal to (3) severe * Edema (Swelling): from (0) normal to (3) severe

• Postoperative donor-site epithelialization of the buccal donor site using Landry Healing Index (HI) Scores

时间窗: post op week 1 and 4

Landry Healing Index (HI) Scores (1-5). The HI scores wound healing on a 1-to-5 scale, where a higher score indicates better, more accelerated healing:

Postoperative donor-site epithelialization of the buccal donor site using Early wound healing score

时间窗: post op day 1

EHS Component Breakdown (Total: 10 points): the higher the score indicate better healing * Clinical Signs of Re-epithelialization (CSR - 6 points max) * Clinical Signs of Hemostasis (CSH - 2 points max) * Clinical Signs of Inflammation (CSI - 2 points max)

次要结局

  • Postoperative pain assessed by Visual Analogue Scale (VAS)(from first day post operative to 12 weeks)
  • Degree of oral aperture restriction (trismus),(Postoperative day 1 through week 12)
  • Oral health-related quality of life(Postoperative weeks 6 and 12)
