title: Long-term follow-up after conservative surgery for bladder endometriosis.
abstract: OBJECTIVE
  To describe the long-term outcome of surgical conservative treatment of bladder endometriosis.
  
  
  METHODS
  Descriptive study.
  
  
  METHODS
  Tertiary referral center for the treatment of endometriosis.
  
  
  METHODS
  Forty-seven patients with symptomatic bladder endometriosis.
  
  
  METHODS
  Partial cystectomy by laparoscopy or laparotomy.
  
  
  METHODS
  Rates of recurrence at a 36-month follow-up.
  
  
  RESULTS
  All 14 patients with isolated bladder dome lesions remained symptom-free. Among the 33 patients with lesions involving the vesical base and vesicouterine septum, cumulative recurrence rates at 36 months were 24.7% and 15.5% for recurrence of symptoms and of clinical-instrumental evidence of lesion, respectively. The only factor influencing rate of recurrence was the extent of surgical excision. When the resection included both the vesical lesion and a 0.5- to 1-cm deep portion of the adjacent myometrium, recurrence was significantly less frequent compared to the removal of the bladder lesion only (7% vs. 37% for symptom recurrence and 0% vs. 26% for clinical-instrumental recurrence, respectively).
  
  
  CONCLUSIONS
  Conservative surgical treatment of bladder endometriosis seems effective in ensuring long-term relief in almost all cases of endometriosis affecting the vesical dome, whereas success rates for deeper lesions involving the vesical base and the vesicouterine septum are lower, depending on the degree of surgical radicality.
