OBJECTIVE: To evaluate the effect of suturing the bladderneck in benign prostatic hyperplasia surgery on bleeding parameter sand surgical outcomes. METHODS: The age, comorbidities, preoperative findings, surgical treatment techniques, peroperative and postoperative bleedingrates, blood transfusion rates, complication rates, surgery note sand postoperative patient follow-ups of the patients operated on for benign prostatic hyperplasia were taken from the patient files. Patients who were sutured to the bladder neck and those who were not were divided into two group sand compared in terms of bleeding and surgical results. RESULTS: A total of 170 patients were included in the study, 106 patients whounder went bladder neck suturing and 64 patients who did not undergo bladder neck suturing. While the mean operation time in hemostatic suture applied group 84.2 ± 7.8 minutes, this time was 61.4 ± 6.3 minutes hemostatic suture not applied group. (p <
0.001)The mean decrease in hemoglobin levels at the 2nd postoperative hour in the suturing group was observed to be greater than in the non-suturing group (2.1 g/dl,2 g/dl, respectively). There was no statistical difference in postoperative blood transfusion rates (15.1%,15.6%, respectively, p = 0.137). Postoperative complications and follow-updata were similar for bothgroup. Bladder neck contracture was higher rate (7.5%vs.3.1%) in hemostatic suture applied group but ıt was not statistically significant. CONCLUSION: Application of hemostatic suture prolongs the operation time of open prostatectomy without affecting bleeding parameter sand postoperative results. For this reason, open prostatectomy surgery is a surgical method that can be performed safely without applying sutures.
