Study presented at the
1st International Interdisciplinary Symposium on
Genitourinary Reconstructive Surgery.
April 6th, 7th and 8th 1998 - Barcelona - Spain

Based on the evidence of human tissue response to stretching a traction device for non-invasive penile lengthening has been designed: The ProExtender™.

- Basic ring, fastened proximally around the root of the penis, abutting on the symphysis.
- Two dynamic metal bars hinged to the ring, connecting it to the silicon-support, fastened around the corona glans at the distal end of the penis.
- By gradually increasing the tractive force on the two metal bars a stretching force is exerted on the corporae of a 600-1500 g.

- Number of patients: 18 patients ranging from 23-47 years
- Inclusion: normal erectile capacity and no penile surgery
- Exclusion: chronically diseases
- Traction force: 0- 2 weeks - 900-1000 g 2-24 weeks - 1000-1200 g
- Treatment period: 12 hours daily 7 days a week 8 to 24 weeks
- Follow up: every 2.week

The average result of ProExtender™ treatment was an increase in erect length of 2,8 cm (1.1 Inch) after 1100 hours at 1200 g traction force. The corresponding flaccid increase is 1,9 cm or 0.75 inch.

- Preliminary study
- All patients achieved penile lengthening after traction with the ProExtender™
- Average lengthening per week was 1,9 mm
- No complications
- Medical indications

a) Non-invasive: hypoplasic penis, Peyronie's disease
b) Postoperative: hypospadias / epispadias, penile lengthening procedures
