[Primary bladder neck obstruction in males].

OBJECTIVES

To report our experience on the diagnosis and treatment of this rare type of infravesical functional obstruction.

METHODS

Over the last ten years we diagnosed and treated 32 males with this entity. We evaluate previous treatments and time to diagnosis. Clinical, radiological, endoscopic, and urodynamic features are evaluated, as well as results obtained with the administration of alpha-adrenergic blockers and endoscopic transurethral incision of the bladder neck.

RESULTS

Patient age ranged from 26 to 48 years (Mean 38.2). All patients presented significant long-lasting lower urinary tract symptoms, having received various non-specific treatments. Uroflowmetry showed a peak of mean flow of 9.8 +/- 3.2 cc/s, being the voiding detrusor pressure 98 +/- 25 cm H2O, with significant post void residual volume in 21 patients (188 +/- 62 cc). Medical treatment with alpha-adrenergic blockers only achieved significant subjective improvement in four patients. Twenty one patients underwent unilateral endoscopic bladder neck incision, obtaining objective and subjective improvements all of them.

CONCLUSIONS

Endoscopic bladder neck incision is the treatment of choice of this dysfunction, being imperative to inform the patient of the risk of retrograde ejaculation as a postoperative sequel, since this entity appears in young males, for whom fertility may be a priority.
