BP,HR,SPO_2 and pertinent side effects were monitored and recorded.Results:The patients in groupⅡexperienced more stable hemodynamics than those in groupⅠ.Obturator nerve reflex was observed in 15 (50.0~%)patients in GroupⅠ,but none(0%)in GroupⅡ(P<0.01).Conclusion:Total intravenous anesthesia with laryngeal mask is a safe,reliable,controllable and simple manual for patient undergoing TURBT.展开更多

Patients and Methods: This was a retrospective study carried out from 2015 to 2019 on 32 patients with bladder tumors that were managed at the Centre medico-chirugical d’urologie in Douala, Cameroon. The relevant data were obtained from patients’ clinical records. Results: A total of 32 patients (25 men and 7 women) aged 29 - 75 years were included in this study. The mean age of the study participants was 58.63 ± 11.00 years. Among our study participants, there were 10 smokers (31.25%). Eight (25%) of them had occupational exposure while 2 (6.25%) had residential exposure to bladder cancer. Thirty (93.75%) presented with hematuria, 2 (6.25%) presented with recurrent urinary tract infections, and 1 (3.13%) presented with acute urinary colic. Nineteen (59.38%) of them were anemic, with 4 (12.5%) requiring blood transfusions. Twenty-seven (84.38%) of them had pedunculated tumors while 5 (15.62%) had sessile tumors. The tumor diameters ranged from 1 cm to 5 cm, with a mean diameter of 2.75 ± 1.22 cm. Complete resection was performed in 27 (84.38%) participants while partial resection was performed in 5 (15.62%) patients. The early single instillation of intravesical chemotherapy with mitomycin was performed in 8 (25%) patients. Only one (3.13%) patient had a postoperative complication, and seven (21.88%) patients experienced tumor recurrence and underwent a second TURBT. Two (6.25%) of the 32 patients died and 30 (93.75%) survived. Conclusion: TURBT is the gold standard method of managing bladder tumors. This procedure is at the same time diagnostic and therapeutic for tumors that do not invade the walls of the urinary bladder.展开更多

Laser techniques have been widely used in urology. This analysis aimed to assess the safety and efficacy of holmium resection of the bladder tumor (HoLRBT)vs. TURBT. Methods A systemic search of MEDLINE, Embase, Web of Science, and The Cochrane Library as well as manual bibliography searches were performed to identify the relevant studies. The pooled estimates of operation time, obturator nerve reflex rate, bladder perforation rate, bladder irrigation rate, catheterization time, hospital stay, and one- and two-year recurrence free survivals were calculated. Results Five studies were enrolled into our meta-analysis. No significant difference was observed in the operation time between groups (weighted mean difference (WMD) 1.01, 95% confidential interval (95% CI) -3.52-5.54, P=0.66). The significant difference in the obturator nerve reflex (OR 0.05, 95% CI 0.01-0.04, P=0.004), bladder perforation (OR 0.14, 95% CI 0.03-0.61, P=-0.009), bladder irrigation (OR 0.13, 95% CI 0.04-0.45, P=0.001), catheterization time (WMD -0.96, 95% C1-1.11 to-0.82, P 〈0.00001), and hospital stay (WMD-1.46, 95% C1-1.65 to-1.27, P 〈0.00001)showed advantages of HoLRBT over TURBT. The 2-year recurrence free survival rate favors the HoLRBT group (OR 1.46, 95% CI 1.02-2.11, P=-0.04). Conclusions As a promising technique, HoLRBT is safe and efficient, and showed several advantages over TURBT. HoLRBT can be used as an alternative procedure for TURBT in terms of low-grade papillary urothelial carcinoma or low-grade early TNM-stage urothelial carcinoma.展开更多
