    Transcript
    Our topic here in this table, incredibly important. And it summarize some of the conditions embryologically and also we’ll go into our adult penile pathologies. We’ll begin by looking at hypospadia. If you take a look at simple picture here, we have the ventral portion of the penis in which that you find an opening. And what does this mean to you? Embryologically, it’s the ventral surface of the penis due to failure of the urethral folds to fuse. What happens? Well, hypospadia’s more common than epi, and you’re worried about with hypo, infection type of issues especially, well, if an organism get’s into -- Take a look at the picture -- that access to the ventral portion, then it might then get into urethra, and then get into the urinary bladder, welcome to cystitis. Everything’s a story. For the most part, 95% of your boards in medicine use concepts. That’s what you should focus on always. And we have epispadia, take a look at where the opening here is and this is on the dorsal surface of the penis. What does this mean to you? This means that you have extrophy of the bladder which is a serious complication. Just to make sure we’re clear, We have due to malpositioning of the genital tubercle, is the embryologic malformation with epispadia. Whereas with hypospadia, what was it? Failure of urethral folds. Well, if your patients in the above two were young because of congenital issues, well, here we’re still discussing penile pathology, but yes, this is also a young patient. However, the problem is with phimosis is that the prepuce, inability to retract the prepuce over the glans. Can you picture that, please? I want you to picture the glans and then let’s say that you have a child that...
