Reduced bleeding with DRY CUT transurethral resection of the prostate (TURP) compared to standard TURP.

To compare bleeding and transfusion rate between patients who undergo standard transurethral resection of the prostate (TURP) and patients who undergo DRY CUT TURP. A retrospective comparison was made of 626 patients who underwent a standard monopolar TURP during 2004-2007 at the Karolinska University Hospital Huddinge with 620 patients who underwent monopolar DRY CUT TURP during 2011-2014 at the same clinic. Transfusion rate, perioperative bleeding, prostate volume, resection weight, use of anticoagulation therapy, presence of prostate cancer, whether the operation was performed by a specialist doctor in urology or a resident and length of hospital stay were evaluated. The median bleeding was 300 ml (IQR = 100-645 ml) in the group of patients who underwent standard TURP compared to 75 ml (IQR 30-268 ml) in the DRY CUT TURP group. The bleeding quotient for standard TURP was 2.3-times the perioperative bleeding for DRY CUT TURP. In a logistic regression model the patients who underwent standard TURP were more likely to undergo blood transfusion compared to DRY CUT TURP (OR = 3.18, 95% CI = 1.72-5.88). The results were not affected by adjustment for patient age, presence of prostate cancer, anticoagulation therapy or operation performed by a specialist in urology. However, the resection weight did influence the bleeding quotient. The shift from standard TURP to DRY CUT TURP has decreased the perioperative bleeding and need for blood transfusion at our hospital.
