The flaps arewell retracted, and the corpus spongiosum, containing the urethra, isdissected from its bed between the corpora cavernosa. It now remains to establish a groove on the under surface of the glans,or a tunnel may be made through that structure for the reception of thedislocated urethra. This may be effected by pushing either a trocar or anarrow straight bistoury through the structure of the glans in the direc-tion of the natural channel, dilating the canal thus constructed by meansof forceps. Or a lateral incision may be made along the edges of theurethral groove, on the under surface of the glans, forming two flaps;the resulting cleft should be sufficiently deep and commodious to ac-commodate the transplanted portion of the urethra. Finally, the edge

The flaps forming the glans are united around the urethra,and the lateral skin-flaps are likewise approximated. It is well to leavea catheter a demeure in place for a few days. Various modifications of the technic for restoring the penile urethrahave been suggested from time to time. Probably one of the mostsatisfactory methods is that devised by Thiersch, and originally em-ployed by him for the relief of epispadias. He first frees the penis fromany existing adhesions, corrects the cur\^ature, and reconstructs theglandular urethra in the manner previously described, after which heendeavors to form the missing portion of the penile urethra. 500 SURGERY OF THE PENIS AND URETHRA.
