Abstract Background Penile inversion vaginoplasty (PIV) is a commonly performed gender-affirming procedure that requires postoperative dilation to maintain vaginal canal patency. Aim To characterize patient-reported dilation experiences and evaluate temporal trends in postoperative outcomes. Methods Consecutive patients undergoing primary PIV at a single center were prospectively surveyed at 1, 3, 6, 9, and 12 months postoperatively. Surveys were author-developed based on clinical experience and clinical review. Surveys assessed dilation frequency, session duration, depth achieved, and challenges encountered. Univariate analyzes were used to evaluate changes over time. Outcomes The primary outcome was the proportion of patients reporting any dilation-related challenge over time. Secondary outcomes included adherence metrics (frequency, days/week, session duration), depth achieved, and specific challenges. Results Seventeen of 27 patients completed all survey time points (63% response rate). On average, participants dilated 6.6 ± 1.4 days/week and 2.4 ± 0.9 times/day; sessions lasted 38.3 ± 16 minutes. Mean depth achieved was 4.05 ± 1.32 (13 cm standardized dilator set), with no significant decline over time. All patients reported at least one difficulty, most commonly tightness (71%), bleeding (71%), pain (65%), discharge (47%), and logistical barriers (24%). The prevalence of reported challenges declined significantly after six months (P < .05). Clinical Implications Early dilation-related difficulties are nearly universal and should be anticipated with proactive counseling and structured postoperative support, though symptoms improve over time. Strengths and Limitations This is the first prospective, longitudinal study of dilation following PIV, using an author-developed survey instrument to capture patient-reported outcomes. Limitations include modest sample size, potential response bias, and lack of assessment of challenge severity. Conclusion Reported dilation adherence following PIV is high, but most patients experience early challenges that diminish over time, highlighting the need for anticipatory counseling and individualized, symptom-responsive dilation protocols.

Objective: We aimed to discern clinico-demographic predictors of large (≥8) tracheostomy tube size placement, and, secondarily, to assess the effect of large tracheostomy tube size and other parameters on odds of decannulation before hospital discharge. Summary of Background Data: Factors determining choice of tracheostomy tube size are not well-characterized in the current literature, despite evidence linking large tracheostomy tube size with posttracheotomy tracheal stenosis. The effect of tracheostomy tube size on timing of decannulation is also unknown, an important consideration given reported associations between endotracheal tube size and probability of failed extubation. Methods: We collected information pertaining to patients who underwent tracheotomy at 1 of 10 U.S. health care institutions between 2010 and 2019. Tracheostomy tube size was dichotomized (≥8 and <8). Multivariable logistic regression models were fit to identify predictors of (1) large tracheostomy tube size, and (2) decannulation before hospital discharge. Results: The study included 5307 patients, including 2797 (52.7%) in the large tracheostomy cohort. Patient height (odds ratio [OR] = 1.060 per inch; 95% confidence interval [CI] 1.041–1.070) and obesity (1.37; 95% CI 1.1891.579) were associated with greater odds of large tracheostomy tube; otolaryngology performing the tracheotomy was associated with significantly lower odds of large tracheostomy tube (OR = 0.155; 95% CI 0.131–0.184). Large tracheostomy tube size (OR = 1.036; 95% CI 0.885–1.213) did not affect odds of decannulation. Conclusions: Obesity was linked with increased likelihood of large tracheostomy tube size, independent of patient height. Probability of decannulation before hospital discharge is influenced by multiple patient-centric factors, but not by size of tracheostomy tube.
