OBJECTIVE: To provide the anatomic basis for the posterior urethral repair via the perineal approach.
METHODS: The anatomic constructions and their relationships of the perineal approach from skin to the membranous and prostate apical urethra were observed and some related data were measured in 12 adult male specimens by microanatomy, and the procedures of urethral repair via the perineal approach were carried out in 3 fresh male specimens.
RESULTS: All the blood vessels and nerves, which supplied the scrotum, the perineum, and bulbourethra, passed lateral-medially. The cavernous nerves coursed posterolaterally from the bottom to the apex of the prostate, pierced the urogenital diaphragm and passed laterally to the membranous urethra in a status of gridding, whose width was (12.11 +/- 2.32) mm.
CONCLUSION: The structures of the perineum and around the posterior urethra are complicated. The strategy for diminishing the damages to them is that all structures must be dissected strictly in the midline. Confining the dissections strictly to the range of 5 mm from the membranous urethra and resecting the apical prostatic tissues anterolaterally could avoid impairments of the cavernous nerves.
