RESUMO
INTRODUCTION: Open adenomectomy of the prostate, although performed less frequently, is still indicated in patients with prostate adenoma > 100 ml. AIM: This study assessed the frequency of isolated bladder neck stenosis after surgery and the effectiveness of internal optical urethrotomy as monotherapy and in combination with transurethral resection in the treatment of this complication. MATERIAL AND METHODS: One thousand five hundred thirty-eight Millin's operations and 381 trans-vesical adenomectomies were performed in patients with prostate adenoma. In 50 patients, the circular hemostatic suture was applied using the de la Peña technique because of bleeding after surgery. The retrospective analysis compared the incidence of isolated bladder neck stenosis depending on the type of surgery. RESULTS: Isolated bladder neck stenosis or narrowing of the neck combined with partial stenosis of the site after adenomectomy occurred in 0.52% (8/1539) of patients after Millin's operation and in 1.05% of patients (4/381) after trans-vesical adenomectomy. All strictures of the bladder after trans-vesical surgery occurred within 12 month after the procedure, and 25% of stenoses after Millin's operation occurred many years after the surgery. Internal optical urethrotomy as monotherapy or in combination with scar resection resulted in recovery after one treatment in 16 out of 17 patients. CONCLUSIONS: Internal optical urethrotomy as monotherapy or in combination with scar resection was effective in nearly all patients with bladder neck stenosis.
