Replantation Following Complete Penile Amputation
Condition: Penile Amputation
Study type: Observational

Summary: 
      The goal of this observational study Replantation following Complete Penile Amputation a case
      series before and after study is to help andrologist and urologists deal with such rare male
      emergencies easily in emergency situation. There are only limited case reports of penile
      amputation, a rare urological emergency with a low treatment success rate, and there are
      still no advanced, detailed surgical or perioperative treatment plans.The main question[s] it
      aims to answer are:

      •The investigators used questionnaire to ask participants who undergo replantation surgery to
      reply. These are the International Index of Erectile Function (IIEF) before and after
      surgery; the International Prostate Symptom Score (IPSS) estimate for urination after
      surgery; the Quality of Life index (QoL) estimate, which characterized quality of life into 7
      categories: happy (0), satisfied (1), general satisfied (2), not bad (3), not too satisfied
      (4), distressed (5), and terrible (6). The appearance satisfaction score was based on four
      levels: from unsatisfactory (1), slight unsatisfactory (2), satisfactory (3) to very
      satisfactory(4).

      Participants (Patients) only need to reply question above. This is observational before and
      after case study.
    

Detailed description: 
      Twenty participants (aged 6-58 years) who were treated at investigators' hospital over the
      past years and ultimately underwent surgery and follow-up assessment were included. The
      relevant research was approved by the Ethics Committee of Sir Run Run Shaw Hospital, Approval
      NO.: 2023-0699. All 20 amputated phalli were adequately preserved; the neurovascular
      structures in the proximal stump were readily identified and in a suitable condition for
      anastomosis. All of these parameters were evaluated by the investigators, who believed that
      anastomosis could be attempted. The surgery was performed under the guidance of the
      investigators, and the same surgical methods were used. Surgical methods and perioperative
      processes were performed as described below. The participants' preoperative erectile
      functions and urination scores are shown in Table 1. Each of the participants and their
      families desired penis replantation after the accident, even if the amputation occurred
      because of a psychological disorder. A participant may not be willing to undergo replantation
      due to psychological issues, but their families are supportive of replantation. And surgeons
      believe that there is high probability of successful anastomosis creation. This participant
      was constraint to undergoing treatment. The participants' details can be found in Table 1.
      The investigators used the International Index of Erectile Function (IIEF) before and after
      surgery; the International Prostate Symptom Score (IPSS) estimate for urination after
      surgery; the Quality of Life index (QoL) estimate, which characterized quality of life into 7
      categories: happy (0), satisfied (1), general satisfied (2), not bad (3), not too satisfied
      (4), distressed (5), and terrible (6). The appearance satisfaction score was based on four
      levels: from unsatisfactory (1), slight unsatisfactory (2), satisfactory (3) to very
      satisfactory(4)
