Meatal Surgery at the Time of Circumcision for Lichen Sclerosus (LS/BXO) Does Not Reduce the Need for Later Meatal Intervention: A Retrospective Cohort Study.

PURPOSE

We describe meatal outcomes for boys undergoing circumcision to treat Lichen Sclerosus (LS/BXO) with a focus on those who underwent meatotomy/meatoplasty at circumcision and factors associated with post-circumcision meatal intervention.

METHODS

Retrospective review of patients undergoing circumcision for histologically confirmed LS between 2011 and 2020. Statistical testing was by Chi2 and multivariate analysis.

RESULTS

382 patients underwent circumcision at a mean of 9.1 years (SD 2.9). At circumcision, LS on the glans was documented in 213/365 (58%). Meatal involvement was documented in 74/382 (19%); 25/382 (6.5%) had a meatotomy, 94/382 (25%) had meatal calibration/dilatation and 234/367 (64%) were prescribed post-operative topical steroids. Patients with LS glans or meatal involvement were more likely to have a meatotomy (p = 0.0013) and to receive post-operative steroids (OR 5, p = 0.0001). Post circumcision, 40/382 (10%) required a median of 1 subsequent procedure (range 1-5), 10 (2.6%) underwent dilatation, 30 (7.4%) had a meatotomy. Patients undergoing meatotomy at circumcision had an odds ratio (OR) of 1.2 for subsequent meatotomy (p = 0.027). Analysis based on requirement for any subsequent procedure identified an OR of 3.1 for having had a meatotomy at circumcision (p = 0.022) and an OR of 6.0 of receiving post-operative steroids (p=<0.001).

CONCLUSIONS

Meatal stenosis following circumcision for LS requiring meatal intervention affected 10% of boys. Meatotomy at circumcision increased the likelihood of subsequent meatal intervention and is therefore not recommended.
