Abstract

PURPOSE
We evaluated the effect of injectable hyaluronic acid gel(HA) for augmentation of the glans penis and treatment of premature ejaculation.
MATERIALS AND METHODS
In 139 patients with premature ejaculation, dorsal neurectomy(Group I; n=25) and glandular augmentation using HA(Group II; n=114) were done. Six months after each procedure, ejaculatory latency, penile vibratory threshold, and patient and partner satisfaction were assessed in both groups.
RESULTS
There was no significant difference in preoperative ejaculation time in the two groups, being 89.2+/-40.3 sec in Group I and 96.5+/-52.3 sec in Group II. Postoperatively, ejaculatory latency was significantly increased, to 235.6+/-58.6 sec in Group I and 324.2+/-107.6 sec in Group II(p<0.01). The postoperative vibratory threshold was also significantly increased in both groups(p<0.01). Satisfaction was expressed by both the patient and his partner in 68%(17/25) and 44%(11/25), respectively, in Group I and 79.8%(91/114) and 64.0% (73/114) in Group II. The maximal glandular girth was significantly increased, from 9.2+/-0.6 cm to 11.0+/-0.4 cm, in Group II.
CONCLUSIONS
Glandular augmentation with injectable HA gel appears to be very effective for the treatment of premature ejaculation. Glandular augmentation with a bulking agent is anticipated to replace the hazardous, irreversible dorsal neurectomy.
