Comparison of perineal urethrostomy versus augmentation urethroplasty in anterior urethral stricture disease

Abstract

Purpose:

Perineal urethrostomy and urethroplasty are very good options for complex and long anterior urethral strictures. A perineal urethroplasty is usually a neglected option. To our knowledge, a comparative study between augmentation urethroplasty and perineal urethrostomy has been not conducted regarding subjective and patient reported outcome measures. We compared both these groups in a high volume tertiary care hospital.

Materials and methods:

A prospective comparative study of augmentation urethroplasty and perineal urethroplasty for long anterior urethral stricture. it was defined by strictures of more than 3 cm. We compared demographic data, urinary and sexual function; and quality of life using validated PROMs (patient-reported outcome measures) between both above groups.

Results:

Both groups had 40 patients each. IPSS score improvement for PU and AUP were 20 and 19.6, respectively(p = 0.1223); IIEF-5 score improvement for PU and AUP at baseline and after 6 months were 14.3 and 16.7, respectively(p = 0.1433); QOL score improvement for PU and AUP were 3.45 and 3.05, respectively; which was statistically significant (p ⩽ 0.001).

Conclusions:

Perineal urethrostomy is a good but neglected option for complex and long anterior urethral strictures and it should be considered one of the reliable treatment option for patients with long-segment urethral strictures.
