“…Regarding our first endpoint on the safety of the procedure in our present study, the perioperative complication rate in the M-TURBT group was statistically insignificant compared to the B-TURBT group. Comparable results were obtained by Liem et al [5] and Del Rosso et al [7], who reported that there was no statistically significant difference in intraand postoperative complications between monopolar and bipolar current. Conversely, Geavlete et al [15] in their randomised study reported more frequent perioperative complications in patients treated with M-TURBT.…”

“…Mashni et al [21] reported that no patients developed bladder perforation, with no statistically difference between the groups. Also Liem et al [5] reported no statistically difference between the groups. Venkatramani et al [18] reported that bladder injury was higher in their bipolar group but was not statistically significant.…”

“…TUR of bladder tumour (TURBT) using monopolar current (M-TURBT) as the source of energy, is the standard of care [4]. However, one of the risks of using hypotonic fluid during M-TURBT is TUR syndrome, although this is more relevant during TUR of the prostate [5]. Also, electric current can easily stimulate the obturator nerve and cause adductor reflex during resection of laterally situated bladder tumours.…”

Objectives: To assess the safety and the effectiveness of bipolar energy in the transurethral resection of primary large bladder tumours (TURBT) and compare it to conventional monopolar energy. Patients and methods: From November 2015 to June 2017, 80 patients underwent endoscopic resection primarily for large bladder cancer tumours of >3 cm. They were randomly assigned into two groups: 40 patients underwent a TURBT with conventional monopolar current (M-TURBT) and 40 were treated with bipolar current (B-TURBT). Results: There were no statistically significant differences between the two groups for the patients' demographic and tumour characteristics. There was a significant difference between M-TURBT and B-TURBT for resection time, obturator reflex, hospital stay, and catheterisation time, which were all higher in the M-TURBT group; the mean (SD) resection time was 26.45 (5.73) vs 22.85 (7.52) min (P = 0.048), the obturator reflex was 25% vs 5% (P = 0.025), the median hospital stay and catheterisation times were 2 vs 1 day (P = 0.012 and P = 0.023, respectively). No statistically significant difference was found between the groups for bladder perforation, TUR syndrome, drop in haemoglobin level, and blood transfusion rate. However, there was statically significant difference in the postoperative haematuria rate, which was higher in the M-TURBT group, at 24 patients vs eight in the B-TURBT group (60% vs 20%; P = 0.01). After 1-year follow-up, there was no significant difference in the recurrence rate between the groups. Conclusion: B-TURBT is a safe and effective alternative procedure to M-TURBT for the management of primary large bladder tumours of >3 cm.

“…Moreover, the postoperative recurrence rates after 2 years favored bTURB over mTURB. A recent study, however, did not find a significant difference between mTURB and bTURB regarding complications, postoperative bleeding, and recurrence-free survival at 12 months [17]. Currently, the results regarding the superiority of bTURB over mTURB remain controversial in terms of operative time, tumor recurrence, and overall complications.…”

Current Standards in the Endoscopic Management of Bladder Cancer: A Survey Evaluation among Urologists in German-Speaking Countries

Introduction: To assess the current diagnostic, treatment, and documentation strategies for bladder cancer (BC) in German-speaking countries. Materials and Methods: A 14-item web-based survey was distributed among members of the German, Austrian, and Swiss Associations of Urology, addressing physicians who perform cystoscopies and transurethral resection of bladder tumors (TURB). Results: The survey was responded to by 308 of 5,564 urologists with a mean age of 49.5 years (response rate: 5.5%). The majority of participants (57.3%) practice in an outpatient setting. White light cystoscopy only is used by 60.2%, with additional photody-namic diagnosis and narrow band imaging by 36.8 and 12.5%, respectively. Endoscopic findings are documented in written form by 93.5%, followed by image capture (33.7%) and a central data archive (20.8%). Inpatient hospital urologists document cystoscopic findings by freehand drawing (21.4 vs. 11.4%, p = 0.017), and with a fixed bladder scheme (31.3 vs. 7.4%, < 0.05) significantly more frequently. Cystoscopic findings are mainly conveyed to other health professionals in written form (77.4%), and significantly more often by inpatient urologists (p < 0.05). Conclusions: Significant differences exist in the approach to documenting and communicating cystoscopic BC findings. Accurate graphic documentation of lesions, visualization of the mucosa's totality, and meticulous consultation of previous surgical reports require improvements to reduce recurrence and progression rates.

“…Similarly, a post-hoc analysis from a randomised trial of various visualisation methods during TURB did not find any statistically significant differences between the two methods. The authors stated that bTURB seems to have no evident advantages over mTURB with respect to operation time, perioperative and postoperative complication rates, and recurrence rates at 12 months [12].…”

Bladder cancer is one of the most common malignancies worldwide. The transurethral resection of bladder tumour (TURB) remains the gold standard in both diagnostics and treatment. Because of the importance of TURB in bladder cancer management and the fact that TURB is one of the most commonly performed urologic procedures, it is the subject of continuous technological development. The latest advances in the field of endourology are aimed at increasing surgical accuracy and thus reducing the risk of bladder tumour recurrence and progression. However, despite the constant progress in technology and technique, there are still a lack of good quality data showing the superiority of any of the methods. The aim of this paper is to present available data on new technological developments in surgical technique of TURB. Advantages and disadvantages of currently available methods are discussed, and literature showing their effectiveness and safety is shown.
