 Objective: To compare the mean perioperative blood loss in monopolar versus bipolar transurethral resection prostate in patients with benign prostatic hyperplasia (BPH).  Methodology: This Randomized Controlled Trial was conducted at Urology Department, Galway University Hospital, Galway, Republic of Ireland from 1st January 2018 to 31st December 2018. Total 100 patients with benign prostatic hyperplasia (BPH) were included. The patients were divided into two groups. Group-A (Monopolar TURP), while Group-B (Bipolar TURP). Pre-operative hematocrit of each study patient was recorded. Patient were followed up after 24 hours of surgery in which hematocrit level was estimated. Blood loss was calculated by recording pre-operative and post- operative (after 24 hours) hematocrit level. Perioperative blood loss in both groups was compared through independent t-test. Data were stratified for age, duration of BPH and size of prostate. A p-value <0.05 was considered significant.  Results: One hundred patients fulfilling the inclusion criteria were included in this study. Patients were divided in two groups i.e. Group-A (Monopolar TURP) and Group-B (Bipolar TURP). The mean age of patients in group-A was 65.4±17.4 years and in group-B was 63.6±14.9 years. In group-A, mean peri-operative blood loss was 351.3±14.84 ml and 299.4±13.01 ml in group-B with a p-value of 0.000001, which is statistically significant.  Conclusion: There is a difference of mean perioperative blood loss in monopolar versus bipolar transurethral resection prostate in patients with benign prostatic hyperplasia (BPH).
