[Endoscopic surgery of bladder diverticulum].

OBJECTIVE

To assess the endoscopic treatment of a vesical diverticulum by incision of the diverticulum opening and mucous fulguration associated to infravesical deobstructive surgery.

METHOD

The procedure was performed in 30 male patients with flowmetry-documented infravesical obstruction. Results were radiologically evaluated, with patients being assigned to one of 3 groups: diverticulum disappearance; size reduction greater than 50% and persistence or size reduction lower than 50%.

RESULTS

Disappearance of diverticulum was verified in 15 patients, size reduction greater than 50% in 9 patients, and persistence or size reduction lower than 50% in 6 patients. The complications rate in this series was 6.6%.

CONCLUSIONS

Endoscopic treatment of a vesical diverticulum with the technique used in our series, was shown to be effective, particularly in diverticula with diameter under 50 mm, and was associated to low morbidity and short hospital stay.
