Yes, it is necessary to stop taking drugs of this type (such as warfarin or aspirin) given the risk of bleeding and bleeding during or after the medical procedure.
The required time of abstinence from these drugs is 10 days before and 10 days after the procedure with the REZUM ™ system. This is a standard protocol not only for this urological treatment but for most minimally invasive procedures.
The REZUM ™ technique does not completely eliminate the transition zone within the prostate where there is a large number of blood vessels that progressively provide lymphocytes and macrophages responsible for engulfing and digesting dead cells from the injury site.
Cellular debris that is not digested is slowly but surely drained into the systemic circulation whereby the site of the "injury" retracts from the outside to the inside.
It is completely normal for about 20% of patients undergoing BPH treatment with the REZUM ™ system to experience discomfort when urinating (dysuria), as well as for 11% to perceive some traces of blood in their urine (hematuria).
These signs are usually mild, transitory and last a few days.
Not at all.
In fact, many patients coming from drug treatments to prevent prostate hyperplasia (such as tamsulonsin) stop taking them after treatment with the REZUM ™ system.
