Brief summary

Currently, perioperative pelvic floor physical therapy (PFPT) is not standard of care for all patients who undergo vaginoplasty surgery. While some practices have implemented these new programs, and the above data exist on outcomes associated with perioperative PFPT in transgender women undergoing vaginoplasty, no study has compared implementation of perioperative PFPT to routine care (no perioperative PFPT). Therefore, the primary objective of this study was to compare the effectiveness of postoperative PFPT compared to no PFPT in transgender women undergoing vaginoplasty surgery for gender affirmation. Secondary objectives of the study are 1) to describe the incidence of preoperative pelvic floor dysfunction in transgender women undergoing PFPT and 2) to compare the effectiveness of postoperative PFPT alone to pre- and postoperative PFPT in these patients.

Detailed description

This was a randomized double-blind study. Both subjects and the surgeon performing the surgery as well as the personnel administering questionnaires to patients postoperatively were blinded to the randomization. Recruitment, Enrollment and Randomization Patients scheduled to undergo vaginoplasty surgery at Cleveland Clinic Main campus were approached about voluntary participation in this study. This occurred over the phone approximately one to three months before their scheduled surgery. Patients who agreed to participate were sent a consent form via the mail and were asked to sign consent in person. Enrollment and randomization occurred following informed consent. All patients were given a copy of their signed and dated consent. Once enrolled, patients were randomized into one of two groups: * Postoperative PFPT * No Postoperative PFPT If patients were randomized into the Postoperative PFPT arm, they were further randomized into the following sub-arms: * Postoperative PFPT alone * Preoperative and Postoperative PFPT Surgery: All patients underwent vaginoplasty surgery by a single surgeon in a standard fashion. The neovaginal cavity was created using the same technique across all patients. Postoperative care was routine and the same for all patients. Postoperative Pelvic Floor Physical Therapy: There was three possible PFPT regimens. All PT regimens were performed by the same two physical therapists, trained in the management of patients who have undergone vaginoplasty surgery. 1. No PFPT Patients were present to see the physical therapist 3 weeks postoperatively. The following interventions were performed: Subjective assessment of bowel and bladder function. Visual and external palpation and assessment of external pelvic floor region. Intravaginal pelvic floor assessment. Pelvic floor muscle dynamics and coordination assessment. Review of pelvic floor anatomy and function. 2. Postoperative PFPT Only Patients presented to the physical therapist 3 weeks and 6 weeks postoperatively. The following interventions were performed: 3 weeks: * Subjective assessment of bowel and bladder function * Visual and external palpation and assessment of external pelvic floor region * Intravaginal pelvic floor assessment * Pelvic floor muscle dynamics and coordination assessment * Instruction of pelvic floor coordination and lengthening * Discussion of dilator program and progression * Home program with instructions 6 weeks: * External scar assessment and treatment if tissue healing allows * Instruction to patient of scar mobilizations * Intravaginal pelvic floor assessment and treatment if indicated * Review of pelvic floor lengthening and coordination * Review and progression of dilator program if appropriate * Assessment of current bowel/bladder symptoms; home program and instructions to address these symptoms 3\) Preoperative PFPT and Postoperative PFPT: Patients presented to see the physical therapist 3 weeks before surgery, 3 weeks and 6 weeks postoperatively. The following interventions were performed: Preoperative: * Diaphragmatic breathing * Discuss dilator positioning/introduce dilator program * External pelvic floor assessment * Teach pelvic floor coordination * Assessment of current bowel/bladder symptoms; home program and instructions to address these symptoms 3 weeks: * Subjective assessment of bowel and bladder function * Visual and external palpation and assessment of external pelvic floor region * Intravaginal pelvic floor assessment * Pelvic floor muscle dynamics and coordination assessment * Instruction of pelvic floor coordination and lengthening * Discussion of dilator program and progression * Home program with instructions 6 weeks: * External scar assessment and treatment if tissue healing allows * Instruction to patient of scar mobilizations * Intravaginal pelvic floor assessment and treatment if indicated * Review of pelvic floor lengthening and coordination * Review and progression of dilator program if appropriate * Assessment of current bowel/bladder symptoms; home program and instructions to address these symptoms Study Questionnaires & Exams: All patients were administered questionnaires preoperatively and 12 weeks postoperatively. The following questionnaires were administered: Preoperatively: * CRAD-8 and UDI-6 * PFIQ-7 Postoperatively 1 week (at the time of routine dilation teaching): • Vaginal length (routine exam) Postoperatively 12 weeks: * CRAD-8 and UDI-6 * PFIQ-7 * PGI-I * Ease of Passing Dilator (VAS 0-10) * Pain with Dilation (VAS 0-10) * Largest dilator size used * Vaginal length (routine exam) Cross-Over Treatment: Any patients in the No PFPT arm who were determined to have pelvic floor dysfunction or symptoms that may have benefitted from PFPT referral, were referred after the 12-week mark. Any patient in one of the PFPT arms who was determined to still need PFPT for persistent pelvic floor dysfunction or symptoms were referred for continued care.

Mean Difference in CRADI-8 Score

Colorectal-Anal Distress Inventory (CRADI-8) provides a symptom inventory (no or yes) and if yes (to measure the degree of bother and distress) caused by the broad array of pelvic floor symptoms, in particular colorectal-anal distress. Responses to the eight questions are scored on a 4-point Likert scale, ranging 1 (not at all) to 4 (quite a bit). The scale scores are found individually by calculating the mean value of their corresponding questions and then multiplying by 25 to obtain a value that ranges from 0 to 100. The reported outcome for this trial is the mean difference in score. A higher CRADI-8 score indicates a greater level of disability. It reflects more significant challenges in daily activities and functioning. A score of 100 is considered to be a worse outcome.

Mean Difference in PFIQ-7-Rectum Score

The Pelvic Floor Impact Questionnaire-7 (PFIQ-7) is a seven-question survey that measures the impact of pelvic floor disorders on quality of life, daily activities, and emotional health. The PFIQ-7 is scored on a scale of 0-300. The mean of each of the three scales is calculated, ranging from 0-3. Each mean is multiplied by 100 and then divided by 3. The scale scores are added together to get the total PFIQ-7 score. The reported outcome measure in this trial is the mean difference in this score pre- and post-intervention. A score of 300 is considered to be a worse outcome.

The Patient Global Impression of Improvement (PGI-I) is a transition scale that is a single question asking the patient to rate their urinary tract condition now, as compared with how it was prior to before beginning treatment on a scale from 1 (very much better) to 7 (very much worse).
