Erectile Dysfunction following Direct Vision Internal Urethrotomy

Abstract

A total of 104 evaluable patients 20–90 years old treated by direct vision internal urethrotomy a.m. Sachse for urethral strictures reported retrospectively via a questionnaire their sexual potency before and after internal urethrotomy. Eleven patients (10.6%) experienced partial or total erectile dysfunction following the operation, most of whom had distal and long strictures. Eight were evaluated for impotence and on grounds of a comprehensive history, physical examination, penile Doppler investigations, and papaverine tests it was concluded that 3 patients might have achieved an abnormal communication between the corpus cavernosum and corpus spongiosum. In two of the patients cavernosographies were carried out and in one total opacification of the corpus spongiosum was demonstrated, but the exact location of the leak could not be pinpointed, and surgical treatment therefore not rendered feasible. Possible factors in the development of erectile dysfunction following internal urethrotomy are analyzed.
