Clinical experiences of penile deviation without epispadia or hypospadia of 28 cases for 5 years were reviewed. The results were as follows; 1. The patient's age ranged from 9 to 66 years with an average of 39.3 years (congenital 23, acquired 49.6 years). 2. Concerning etiology of the deviation, 9 cases (32.1%) were congenital including asymmetrical development of corpus cavernosum in 6 cases and hypoplasia of corpus cavernosum in 3 cases, and 19 cases (67.9%) were acquired including Peyronie's disease in 16 cases (89.4%), penile trauma in 2 and penile tuberculosis in 1. 3. Duration of the penile deviation ranged from 1 to 48 months with an average of 13.1 months and within 6 months was most common (35.5%). 4. Regarding to direction of the deviation, deviation to ventral and left side was most common (77.8%) in congenital but dorsal (42.1%) and ventral (36.9%) deviation were most common in acquired type. Regarding to extent of the deviation, 4 cases were over 45o and 5 cases below 45o in congenial, and 6 cases were over 45o and 6 cases below 45o in acquired. 5. Painful erection was observed in 9 (64.3%) out of 14 cases of the acquired deviation but in only 1 out of 7 cases of congenital deviation. Poor erection was presented in 3(37.5%) out of 8 cases of congenital deviation and 8(47.1%) out of 17 cases of a acquired deviation. 6. Corrective surgeries were done in 4 out of 6 congenital deviations. For treatment of acquired deviation, vitamine E was administered to 12 cases (63.1%), only observation was done in 2 and corrective surgeries in 2. In conclusion, congential deviation was presented around twenty years, showed usually ventral or lateral deviation an required surgery for correction. But acquired deviation was presented around fifty years, accompanied pain on erection and poor erection more frequently than congenital, showed usually dorsal or ventral deviation, and required medical therapy first. There was no difference in extent of the deviation.
