 hypospadias | 1/500 males termination of urethra on Ventral surface of penis no corpus spongiosum enclosure |
| epispadias | termination of urethra on Dorsal surface of penis |
| phimosis | tightening of foreskin that prevents its retraction over the glans |
| paraphimosis | foreskin is so tight and constricted that it cannot cover the glans leads to ischemia of the glans |
| priapism definition | involuntary prolonged and painful erection not related to sexual excitement may last more than 24 hours |
| priapism incidence | peak age 5-10 and 20-50 |
| priapism low flow mechinism | static or ischemic blood flow in corpus cavernosum --> fibrosis --> impotence |
| priapsim high flow mechinism | non-ischemic, persistent blood flow into corpus cavernosum |
| priapism primary classification | tumor infection, trauma |
| priapism secondary classification | hematologic disorder- stroke (plaque interferes with blood flow), drugs, antidepressants, antihypertension medication (vasodilation) |
| Peyronie's disease cause/onset | unknown cause middle-age or elderly |
| Peyronie's disease pathogenesis | localized and progressive fibrosis of tunica albuginea of corpus cavernosum -->plaque --> calcification |
| Peyronie's disease complications | painful and difficult intercourse due to prevention of lengthening of the affected area during erection |
| balanitis | acute or chronic inflammation of glans penis causing pain, swollen inguinal lymph nodes, malodorous discharge |
| balanoposthitis | inflammation of glans penis and prepuce causing pain, swollen inguinal lymph nodes, malodorous discharge |
| balanitis/balanoposthitis cause | overgrowth of bacteria, secretion, smegma (dead cell) in male with phimosis or redundant prepuce |
| cancer of the penis cause/onset | unknown cause, possibly due to poor genital hygiene and phimosis age 40-60 (1% in U.S.) |
