Bipolar transurethral resection of the prostate (B-TURP) is a recent technique in our urological practice. The aim of this study was to evaluate our preliminary results on the use of a B-TURP in Kolda (Senegal) in a benign prostatic hyperplasia (BPH). Materials and Methods: This was a 15-month, retrospective and descriptive study from June 2021 to August 31, 2022. It examined the records of patients who had BPH requiring surgical treatment and who received Bipolar transurethral resection of the prostate (B-TURP) during the study period at the Kolda Regional Hospital in Senegal. We used a Karl STORZ bipolar endoscopy column with a 26 sheath and 30˚ optics. The parameters studied were the civil status of the patients, the clinical and para-clinical data as well as the operative indications. The data were entered and analyzed using Epi-info 3.5.1.1. Results: A total of 31 patients underwent bipolar transurethral resection of the prostate during the study period. The mean age of patients was 68.5 ± 12.6 years (range, 56 - 77 years). The mean total PSA was 4 ± 2.3 ng/ml (range, 0.5 - 11 ng/ml). The mean prostate size assessed by ultrasound was 54 ± 12.3 ml (range, 30 - 90 ml). The operative indication was dominated by BPH with impact on the upper urinary tract. The mean of bladder irrigation time was 21.4 ± 3.9 hours (range, 12 - 26 hours). In the immediate post-operative period, blood transfusions were performed in 2 patients (6.5%). In the medium-term follow-up, we noted one 1 (3.2%) case of urine retention requiring bladder catheterization. Conclusion: Bipolar Transurethral resection of the prostate B-TURP in saline system is efficacious and safe. The results of this preliminary study of B-TURP are satisfactory with a low complication rate. B-TURP decreases the duration of the hospitalization and the port of the probe. Our perspectives are oriented towards endoscopy of the upper urinary tract.展开更多

Long-term follow-up of the clinical effect of bipolar transurethral resection of the prostate (B-TURP) in saline for BPH is required. Objective: To compare, with long term follow-up, the efficacy and safety of B-TURP in the treatment of BPH with prostate gland volumes of 45 ml, and larger than 60 ml. Materials and Methods: From January 2006 to December 2016, 318 patients with a mean age of 69.45 ± 8.37 years and a median prostate volume of 42 cm3 (56.51 - 32.47) were treated with B-TURP by single urologist (SP) at the Division of Urology, Department of Surgery, Faculty of Medicine, Ramathibodi Hospital, Mahidol University. We retrospectively analyzed the perioperative status of patients’ status follow-up for at least 6 months and up to 5 years. Post-void residual (PVR) and maximum flow rate (Qmax) were assessed preoperatively and postoperatively. Operative time, length of catheterization and hospitalization and complications were all reported. Results: The main indication for B-TURP was failure of medication (81.13%). Perioperative results showed no statistical significance among the groups in terms of catheterization days and the hospitalization length. During the follow-up, the improvement of postoperative parameters was compared with preoperative subscales, at different periods from baseline and after 24, 36, 48, and 60 months post treatment. PSA, Q max, PVR, and average flow rate were significantly different from pre-operation data (p Conclusion: With long-term follow-up, B-TURP is a safe and effective technique for BPH management with prostate gland 45 ml and larger than 60 ml.展开更多

This study aimed to evaluate the results of bipolar transurethral prostate resection in a single urology center in Cameroon. Materials and Methods: This was a retrospective study carried out over two years (2015-2017) involving 112 patients with symptomatic prostate diseases who underwent transurethral prostate resection with the help of a bipolar Olympus generator. Results: The ages of the participants ranged from 44 years to 85 years, with a mean age of 64.41 ± 9.5 years. Fifty-six (50%) patients presented with only obstructive symptoms, five (4.46%) had only irritative symptoms, twenty (17.86%) presented with both obstructive and irritative symptoms, eight (7.14%) presented with macroscopic hematuria, seven (6.25%) with urinary tract infections, and sixteen (14.29%) with acute urinary retention. Digital rectal examination was unremarkable in 74 (66.07%) findings and was positive in 38 (33.93%) patients. The median prostate diameter was 70 [59 - 86.5] mm. The mean preoperative IPSS was 24.46 ± 5.68. The mean surgery duration was 77.61 ± 23.87 minutes. The mean volume of irrigation fluid used during surgery was 24.84 ± 6.40 ml. The differences between the preoperative and postoperative mean IPPS score, maximum urine flow rate, and quality of life were statistically significant (all P Conclusion: Bipolar transurethral prostate resection is a viable alternative to open surgery or laparoscopic surgery for large prostate glands. This technique is also associated with a reduction in prostate-related morbidity.展开更多
