Objective To study safety and efficacy of transurethral Thulium laser resection of high-risk stage bladder tumor in anticoagulant state.Methods A total of 26 non-muscle invasive bladder cancer patients receiving long-term anticoagulant therapy,including 16 cases with cerebral infarction,7 cases with coronary heart disease,3 patients with coronary stenting,were retrospectively analyzed in our hospital from July 2012 to July 2014.In condition not stopping anticoagulants,Thulium laser transurethral resection of bladder tumor was performed,and hemoglobin,thrombin time,the operative time,intraoperative blood loss,postoperative bladder irrigation duration,postoperative hospital stay,bladder tumor recurrence within two years,the postoperative complications were recorded before and after surgery.Results All patients were successfully treated.The operative time was(29.1 ± 12.8) min,int raoperative blood loss was (29.4 ± 16.9) ml portions,postoperative bladder irrigation time was (1.25 ± 0.55) d,postoperative hospital stay was(5.51 ± 1.06) d.Hemoglobin before and after operation were (131.35 ± 6.57) g/L and (129.75 ± 11.05) g/L respectively,there was no statistically significant differences (t =1.014,P > 0.05) between them.Prothrombin time before and after operation were (12.50 ± 0.25) s and(12.44 ± 0.27) s,with no statistically significant difference (t =0.908,P>0.05)between them.During the followed-up of 48 months,tumor recurred at heterotopia in 2 patients.Conclusions Thulium laser transurethral resection of bladder tumor is safe and effective for patients undergoing long-term oral anticoagulation drugs,without a needto stop taking anticoagulant drugs.

Objective To explore the efficacy and safety of 980 nm diode laser therapy for treatment of benign prostatic hyperplasia (BPH). Methods Data of 170 patients with BPH treated with 980nm diode laser system were reviewed. The mean operative time, blood loss, surgical complications, the international prostate symptom score (IPSS), bladder residual urine volume and flow rate changes were collected and analyzed. Results One hundred and seventy cases were safe during the perioperative period. The average operation time was (74 ± 11) min, surgical removal of prostate tissue mass of (54±12) g, blood loss (72±11) ml. There was no TUR syndrome occurred. 170 patients were followed up 2 to 24 months. The IPSS decreased from preoperative 25.0±5.5 to 9.0±2.5. The maximum flow rate increased from preoperative (6.2±2.3)ml/s to post-operative (17.4±3.5) ml/s. The residual urine volume decreased from preoperative (210.0±25.6) ml to postoperative (25.2±4.6) ml. All the differences were statistically significant (P<0.05). Conclusion Transurethral vaporization of 980 nm diode laser could be a safe and effective treatment modality for BPH.

【Objective】 To investigate the efficacy, safety and feasibility of laparoscopic lymph node dissection guided by indocyanine green (ICG) fluorescence imaging. 【Methods】 A total of 30 patients with muscle-invasive bladder cancer (MIBC, T2/T3NxM0) who were admitled to the Cangzhou People’s Hospital during Mar.2018 and Jun.2022 were included.The lymph nodes were cleared with ICG fluorescence imaging first, and then the remaining lymph nodes were cleared according to the standard pelvic lymph node range.The lymph node positive rate of ICG fluorescence imaging guided laparoscopic lymph node precise dissection and standard pelvic lymph node dissection was analyzed by self-comparison. 【Results】 ICG fluorescence imaging guided laparoscopic lymph node precise dissection needed shorter operation time than standard pelvic lymph node dissection \[(21.80±6.80) min vs.(47.70±10.73) min, P<0.05\].There was no significant difference in the lymph node positive rate between the two approaches \[(11.34±9.06)% vs. (12.36±9.43)%, P>0.05\], but the former approach caused less damage on blood vessels and nerves. 【Conclusion】 Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable efficacy to standard pelvic lymph node dissection, which can reduce ineffective lymph node dissection, shorten the operation time, and reduce the risk of complications.
