Sixty ASA Ⅰ-Ⅱ patients undergoing TURBT were randomly assigned to 2 groups. Spinal anesthesia with 0. 75% pure bupivacaine （8-12 rag） was applied to patients in Group Ⅰ （n= 30）. Patients in Group Ⅱ （n=30） received total intravenous anesthesia with continuous infusion of Propofol and Remifentanil ; and a laryngeal mask was used to ensure the airway and ventilation. BP, HR, SPO2 and pertinent side effects were monitored and recorded. Results ： The patients in group Ⅱ experienced more stable hemodynamics than those in group Ⅰ . Obturator nerve reflex was observed in 15 （50. 0%） patients in Group Ⅰ , but none （0%） in Group Ⅱ （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

The purpose of our study is to evaluate the anatomical distribution of ureteralostia in normal bladders and those with thickened walls. Materials and Methods: We dissected 30 vesical-prostate blocks from human cadavers and identified the ostia of the bladder trigone. A computerized morphometric analysis was performed to measure the thickness of the detrusor muscle, the distances between the ureteral ostia themselves and the distances between each ureteral ostium (left—LUO and right—RUO) and the internal urethral ostium (IUO). The angle formed between the IUO and LUO/RUO was also recorded as well as the volume of the prostates. Results: Fifteen bladders with a non-thickened detrusor (6 mm) were identified. The average prostatic volume of the dissected blocks was 23.7 cm3. The distance between ureteral ostia, the distance from IUO to LUO, the distance from IUO to RUO and the angle formed between IUO and LUO/RUO in normal and thickened bladder were, respectively, 1.9 cm/2.2 cm (p = 0.09), 1.6 cm/1.6 cm (p = 0.82), 1.6 cm/1.7 cm (p = 0.79) and 77/91 (p = 0.17). Conclusions: Our study shows that there is no significant difference in the position of bladder ostia in healthy and thickened bladders. We believe that our findings may facilitate locating the ureteral orifices in situations where endoscopic identification is difficult.展开更多

For patients in control group, treatment of Pirarubicin postoperative immediately bladder irrigation was provided after transurethral resection of bladder tumors. For patients in combination group, combined treatment of Pirarubicin postoperative immediately bladder irrigation and compound matrine injection were provided after transurethral resection of bladder tumors. T lymphocyte subsets, cytokines, liver and renal functions of patients in each group were detected before and after treatment.Results: No statistical difference showed on T lymphocyte subsets, cytokines, liver and renal functions between two groups of patients with superficial bladder cancer before and after treatment. Compared with prior treatment, CD8+, cytokines (IFN-γ and IL-2), liver function indexes (AST and ALT) and renal function indexes (BUN and Cre) were significantly increased in two groups of patients after treatment, while T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and cytokines (TNF-α, IL-6 and CRP) were significantly decreased. Differences showed statistical significance. After combined treatment given, T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and cytokines (IFN-γ and IL-2) in combination group were significantly higher than in control group after treatment, cytokines (TNF-α, IL-6 and CRP), CD8+, liver function indexes (AST and ALT) and renal function indexes (BUN and Cre) were significantly lower than in control group after treatment. Differences between the two groups showed statistical significance.Conclusion:Combination of Pirarubicin postoperative immediately bladder irrigation and compound matrine injection could enhance immune functions, improve inflammatory reactions and decrease chemotherapeutics toxicities for patients with superficial bladder cancer. It is of great significance on clinical therapy for those patients.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

文摘Introduction: The ureteral ostia may not be easily identified in urological endoscopic procedures, leading to an incomplete diagnosis of urinary tract diseases or a predisposition to iatrogenic lesions. The purpose of our study is to evaluate the anatomical distribution of ureteralostia in normal bladders and those with thickened walls. Materials and Methods: We dissected 30 vesical-prostate blocks from human cadavers and identified the ostia of the bladder trigone. A computerized morphometric analysis was performed to measure the thickness of the detrusor muscle, the distances between the ureteral ostia themselves and the distances between each ureteral ostium (left—LUO and right—RUO) and the internal urethral ostium (IUO). The angle formed between the IUO and LUO/RUO was also recorded as well as the volume of the prostates. Results: Fifteen bladders with a non-thickened detrusor (6 mm) were identified. The average prostatic volume of the dissected blocks was 23.7 cm3. The distance between ureteral ostia, the distance from IUO to LUO, the distance from IUO to RUO and the angle formed between IUO and LUO/RUO in normal and thickened bladder were, respectively, 1.9 cm/2.2 cm (p = 0.09), 1.6 cm/1.6 cm (p = 0.82), 1.6 cm/1.7 cm (p = 0.79) and 77/91 (p = 0.17). Conclusions: Our study shows that there is no significant difference in the position of bladder ostia in healthy and thickened bladders. We believe that our findings may facilitate locating the ureteral orifices in situations where endoscopic identification is difficult.
文摘Bladder tumor is characterized by recurrent recurrence and distant metastasis,which determines the difficulty of completely curing bladder tumor.In recent years,the number of patients with bladder cancer is increasing,and the treatment of bladder cancer has become an important direction of clinical research.It is difficult to control bladder tumor by traditional therapy.Photodynamic therapy(PDT),as a new optical therapy,has gradually become the main method in clinical treatment of bladder tumor combined with transurethral resection of bladder tumor.In this paper,a patient with superficial recurrent bladder tumor was treated by photodynamic therapy combined with transurethral resection of bladder tumor.The advantages of photodynamic therapy in the treatment of bladder tumor and the selection of photosensitizer in the process of photodynamic therapy were discussed.After two recurrences,the patients chose photodynamic therapy.The tumors were resected one by one,and the wound was coagulated by roller electrode.After the drug was retained for 20 minutes,the bladder was empty.The spherical optical fiber was implanted into the bladder.The photodynamic energy was adjusted(light power 1.8 W,light time 1302 s).There was no recurrence after operation.Most bladder tumors are superficial tumors,and bladder is a cavity organ,which determines that bladder is an ideal organ for photodynamic therapy.As a targeted drug,photosensitizer is only absorbed by bladder tumor after being perfused into bladder.The photosensitizer forms reactive oxygen species through oxygen and kills tumor cells.Clinical practice has proved that PDT has its unique advantages for superficial and recurrent bladder tumors.As the first generation photosensitizer,xipofen also has selectivity in the treatment of bladder cancer.

For patients in control group, treatment of Pirarubicin postoperative immediately bladder irrigation was provided after transurethral resection of bladder tumors. For patients in combination group, combined treatment of Pirarubicin postoperative immediately bladder irrigation and compound matrine injection were provided after transurethral resection of bladder tumors. T lymphocyte subsets, cytokines, liver and renal functions of patients in each group were detected before and after treatment.Results: No statistical difference showed on T lymphocyte subsets, cytokines, liver and renal functions between two groups of patients with superficial bladder cancer before and after treatment. Compared with prior treatment, CD8+, cytokines (IFN-γ and IL-2), liver function indexes (AST and ALT) and renal function indexes (BUN and Cre) were significantly increased in two groups of patients after treatment, while T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and cytokines (TNF-α, IL-6 and CRP) were significantly decreased. Differences showed statistical significance. After combined treatment given, T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) and cytokines (IFN-γ and IL-2) in combination group were significantly higher than in control group after treatment, cytokines (TNF-α, IL-6 and CRP), CD8+, liver function indexes (AST and ALT) and renal function indexes (BUN and Cre) were significantly lower than in control group after treatment. Differences between the two groups showed statistical significance.Conclusion:Combination of Pirarubicin postoperative immediately bladder irrigation and compound matrine injection could enhance immune functions, improve inflammatory reactions and decrease chemotherapeutics toxicities for patients with superficial bladder cancer. It is of great significance on clinical therapy for those patients.
文摘Background Transurethral resection of the bladder tumor （TURBT） remains the gold standard for non-muscle-invasive bladder cancer （NMIBC）. 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.
