A comparative study of monopolar versus bipolar transurethral resection of prostate for the management of benign prostatic enlargement with particular reference to post operative complications

Background: Benign prostatic hyperplasia (BPH) is a very common disease seen in old age men and incidence increases with increasing age of the individual. The incidence of lower urinary tract symptoms like voiding and irritative (LUTS) secondary to BPH affects about 3% of male between 45 and 49 years of age, rising to above 30% in men over 80 years of age. Monoplar TURP (M-TURP) considered as a gold standard procedure for the resection of the prostate though bipolar TURP (B-TURP) has some benefits over the M-TURP. Methods: 82 patients with eligible criteria sample size were taken. These patients were randomly divided into 2 groups: group 1 (41 patients) underwent M TURP, while group-2 (41 patients) underwent B-TURP. Results: 82 patients were operated with M-TURP and B-TURP 41 patients each. Mean age of the patient was 66.4 years in M-TURP and 67.5 year in B-TURP, time of resection was more in B-TURP 51.3 min and 45.6 min in M-TURP. Residual prostate volume was less in B-TURP. PVRU improvement was more in B-TURP. Post op clot retention, TUR syndrome, mean fall in haemoglobin and blood transfusion was more in monopolar TURP. Conclusion: B-TURP and M-TURP both procedures are good and improves lower urinary tract symptoms, although B-TURP is associated with less risk of dilutional hyponatremia, TUR syndrome, and blood loss, need of blood transfusion compared to M-TURP.
