Diagnosis and treatment of priapism / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the diagnostic approaches and treatment choices for priapism,and to upgrade the diagnostic and therapeutic efficacy. Methods Thirteen patients with priapism were evaluated by physical examinations,cavernous blood gas analysis,color duplex ultrasonography and cavernosography.Among them 9 cases of priapism resulted from intracavernosal injection of vaso-active agents,1 from perineal trauma and 3 from unknown cause.All the 13 patients were treated with intracavernosal injection of aramine and cavernosal decompression. Results Among these cases of priapism,12 were of low-flow and 1 was of high-flow.After the treatment,all the patients with priapism achieved remission.During the follow-up of 3 to 43 months,4 cases experienced decreased erection;9 had no significant change of erection.No cavernous fibrosis of penis occurred in them. Conclusions Cavernous blood gas analysis and color duplex ultrasonography are helpful with the accurate and timely dignosis of priapism.Cavernosal decompression and intracavernosal injection of arimine can be applied to most of the patients,and in the course of the treatment systemic adverse events should be avoided.
