Priapism is a medical condition characterized by a prolonged and often painful erection of the penis that lasts for hours beyond, or is unrelated to, sexual stimulation. There are two main types of priapism:
Ischemic (Low-Flow) Priapism: This is the more common and serious type, where blood gets trapped in the erectile chambers of the penis and cannot flow out. It requires prompt medical treatment to prevent tissue damage and permanent erectile dysfunction.
Non-Ischemic (High-Flow) Priapism: This type is less common and usually less painful. It occurs when there is unregulated blood flow into the penis, often due to an injury to the perineum or penis.
Ischemic (Low-Flow) Priapism: Blood becomes trapped in the penis, unable to drain, leading to prolonged erection and potential tissue damage due to lack of oxygen.
Non-Ischemic (High-Flow) Priapism: A rupture in an artery causes continuous blood flow into the penis, leading to an erection that is less rigid and less painful compared to ischemic priapism.
The symptoms of priapism can vary depending on the type:
Priapism can be caused by a variety of factors, ranging from medical conditions and medications to trauma and lifestyle choices. Here are the primary causes of both ischemic (low-flow) and non-ischemic (high-flow) priapism:
Ureteroscopy (URS) is a minimally invasive procedure used to diagnose and treat conditions of the urinary tract, particularly kidney stones.
RIRS (Retrograde Intrarenal Surgery) is a minimally invasive surgical procedure used to treat kidney stones located within the kidney.
PCNL (Percutaneous Nephrolithotomy) is a minimally invasive surgical procedure used to remove large kidney stones, typically those that are too large to be passed naturally.
Miniperc (Mini Percutaneous Nephrolithotomy) is a minimally invasive surgical procedure used to remove kidney stones that are larger than what can typically be treated by other procedures.
ECIRS (Endoscopic Combined Intrarenal Surgery) is an advanced minimally invasive surgical approach used to treat complex kidney stones.
Cystolithotripsy is a surgical procedure used to remove bladder stones.
Laparoscopic pyelolithotomy is a minimally invasive surgical procedure used to remove kidney stones (renal calculi) that are too large or complex to be treated.
Laparoscopic ureterolithotomy is a minimally invasive surgical procedure used to remove stones (ureteral calculi) from the ureter, the tube that carries urine from the kidney to the bladder.
