Objective: Benign prostatic hyperplasia (BPH) is the one of the most common disease in the world. Transurethral resection of prostate (TURP) is the gold standard procedure in BPH surgery. So TURP methods are important. The aim of our study is to compare bipolar (B) TURP and monopolar (M) TURP methods.

Methods: In our study is included 120 patients who underwent TURP due to BPH. The patients were examined in two groups of 60 people. M-TURP was applied to one group while B-TURP was applied to the other group. Patients International Prostate Symptom score (IPSS), uroflowmetry (Qmax), hemoglobin loss, postoperative catheterization time, hospital stay, TUR syndrome and 6th month postoperative urethral stricture parameters were investigated. In the statistical analysis, chi-square, Student’s t-test and Wilcoxon test were performed.

Results: Two groups were analyzed separately and compared. In IPSS, Qmax, hospital stay, hemoglobin loss parameters there was no significantly difference between two groups. The duration of postoperative catheterization and development of urethral stricture at postoperative 6th months found statistically significant; in the M-TURP group, more stricture development and longer catheterization time were observed (p<0.05). At the same time TURP syndrome was observed in 2 patients in M-TURP group and TUR syndrome was not observed in B-TURP group (p<0,05).

Conclusion: B-TURP and M-TURP groups were compared. The results of both groups were similar. Only in the B-TURP group, in terms of the probability of stricture and the development of the TUR syndrome was more advantageous than M-TURP. In conclusion, B-TURP is more reliable method than M-TURP and both methods can be reliably applied in BPH surgery.
