Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Rezūm is a radiofrequency made water vapour thermal treatment. It has recently been added to the international guidelines as a choice for medical treatment resistant lower urinary tract symptoms (LUTS). The AUA and Canadian Urological Association (CUA) guidelines now add water vapour therapy as a treatment option for BPH patients with small prostate size \<80 gm and for those wishing to maintain antegrade ejaculation. While they still offer no clear recommendation to Rezūm use for those with large prostates. Early studies on this topic have found out promising results.

Study Groups

BPH patients treated with Rezum procedure
Patients aged 50-80 years with prostate volumes of 50-120 ml, sexually active, and have severe LUTS treated with Rezum procedure
Rezum procedure
In Rezūm procedure, the Rezūm System (NxThera Inc., Maple Grove, MN, USA) consists of a radiofrequency (RF) power supply generator and single-use transurethral delivery device. Starting 1 cm distal to the bladder neck, injection was done at 3 and 9 o'clock sites. The needle was inserted for 9 s duration, retracted, and then delivered to another treatment site in 1 cm distance distal to the previous one.
BPH patients treated with B-TURP procedure
Patients aged 50-80 years with prostate volumes of 50-120 ml, sexually active, and have severe LUTS treated with Rezum procedure
B-TURP procedure
In B-TURP, Olympus SurgMaster™ UES-40 bipolar generator (Olympus Europe, Hamburg, Germany) was used. Current's settings used were cut/coag 200/120. Using continuous flow 26Fr resectoscope first resection of the median lobe from the level of the bladder neck to the apex of the prostate was done followed by resection of the lateral lobes. Using Ellic evacuator, Prostatic chips were extracted from the field. A 22 fr three-way silicon Foley catheter was placed with traction applied and the balloon inflated by normal saline of 30-80 cc according to the size of the prostate.
