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

Objective: To compare bleeding and transfusion rate between patients who undergo standard transurethral resection of the prostate (TURP) and patients who undergo DRY CUT^® TURP.Materials and methods: 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.Results: 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.Conclusions: The shift from standard TURP to DRY CUT^® TURP has decreased the perioperative bleeding and need for blood transfusion at our hospital.
