Urology Library
PeeDoc has been a source of urology information for more than two decades. This library brings that together in one place.
It is an education library rather than a list of everything I currently treat.
Highlighted topics are ones I treat, or give second opinions on, at Peri Health & Hormones. The rest are here as education.
Why hormones are a cornerstone of urology rather than a departure from it.

A 6 mm stone and a 6 cm stone are not the same problem. What your report actually says, the odds a stone passes, how long it takes, and the one symptom that means go to the ER tonight.

Everyone knows what smoking does to lungs. Almost nobody knows it is the biggest cause of bladder cancer, or that it shows up in the bedroom years before it reaches the heart. A urologist's case for quitting, and how to actually do it.
Read article →This library is kept because the education is genuinely useful and people still search for it. PeeDoc is not a full-service urology practice.
What I still treat directly: kidney stones and stone prevention, enlarged prostate with the minimally invasive options, complex voiding dysfunction, recurrent and complex urinary infection, and vasectomy. Complex urologic second opinions are welcome, including complex PSA and prostate decisions, where a second look is often worth more than a second procedure.
What I do not do: nephrectomy, radical prostatectomy, and the surgical management of kidney, testicular and penile cancer. If that is what you need, the right move is to find a surgeon who does those regularly. I am glad to help you work out what to ask.
