OBJECTIVE: To explore the clinical application value of using needle electrode in transurethral plasmakinetic resection of bladder tumor around ureteral orifice. METHODS: Retrospective analysis was performed on the clinical data of 16 cases who had bladder tumors around ureteral orifice and underwent transurethral resection using plasmakinetic needle electrode in Department of Urology, Peking University International Hospital from June 2015 to December 2019. There were nine cases with the tumor of one to two centimeters from the ureteral orifice. The rest of the seven cases had tumor that was within one centimeter from the ureteral orifice, including two cases whose ureteral orifice was invaded by the tumor. All the patients studied were diagnosed before surgery and contraindications were excluded. The plasmakinetic needle electrode was used to treat the tumor with en bloc resection, and all the excised tissue was sent for pathological examination. Intravesical chemotherapy and postoperative follow-ups were performed. Statistical analysis was performed on the operation time, the incidence of obturator nerve reflex, the peri-operative bleeding, the parameters of indwelling ureteral catheter or double-J stent, the incidence of postoperative hydronephrosis, the clinical stage of tumor, and the recurrence rate. RESULTS: The operation was successfully completed for all the sixteen cases. The operation time was 16 to 57 minutes, with an average of (32.6±11.8) minutes. No obvious obturator nerve reflex and perioperative bleeding occurred in all the patients. Ureteral catheters were indwelled prior to the operation of tumor resection in seven cases. Four of the seven cases had the ureteral catheters remained while the rest three were replaced by double-J stent after surgery. Postoperative pathological analysis showed that all the tumors were urothelial carcinoma, including 9 cases of low grade and 7 cases of high grade. Pathological staging: 10 cases were in Ta stage, 5 cases in T1 stage, and 1 case in T2a stage. All tumor bases and lateral margins were negative. All the patients received 3-56 months, with an average of (26.0±18.1) months of follow-up. There was no case of upper urinary tract hydronephrosis or tumor recurrence. CONCLUSION The transurethral plasmakinetic resection of bladder tumor using needle electrode can realize en bloc tumor resection without obturator nerve reflex and reduce the risk of ureteral orifice injury. It is a safe and effective surgical method for treating bladder tumors around the ureteral orifice.

OBJECTIVE:To investigate the characteristics and general pattern of the adverse drug reactions (ADR) occurred in our hospital. METHODS:A total of 258 ADR cases collected from June 2006 to June 2008 were analyzed statistically in respect of patients' age and sex,drug variety,clinical manifestations,routes of administraiton and dosage forms etc. RESULTS:Of the total 258 ADR cases,the majority(64.34%) were induced by antimicrobial drugs; 45.74% presented with lesions of skin and its appendants,and 77.91% were induced by intravenous way. CONCLUSION:To develop and strengthen ADR monitoring and reporting should be regarded as the key to enhance medication safety.

Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

Objective:To describe the clinical results of a one-stage operation for posterior cruciate ligament reconstruction and a posterolateral corner reconstruction of popliteus tendon reconstruction,com-pared with an open popliteofibular ligament reconstruction.Methods:Our study included 33 patients who had undergone posterior cruciate ligament reconstruction with use of an achilles tendon-bone allograft and posterolateral corner reconstruction with arthroscopic anatomical reconstruction of popliteus tendon or open reconstruction of popliteofibular ligament.The patients were assessed for knee instability with use of the dial test at 30°and 90°,together with posterior stress radiography and KT-1000 measurement.Re-sults:The mean time of follow-up was more than 2 years.At the final follow-up evaluation,the tibial posterior translation as measured by stress radiography at 90°of knee flexion,the anterior-posterior trans-lation as measured by KT-1000,and the external rotation of tibia as measured by dial test were reduced postoperatively (P<0.001 )in both groups.Between the two groups,the preoperative tibial posterior translation as measured by stress radiography and the preoperative mean anterior-posterior translation as measured by KT-1000 in the popliteofibular ligament group were a little more than those in the popliteus tendon group (P=0.014,P<0.001).But the other comparisons were not significantly different (P>0.05).The final flexion losses were 3.33°±4.88°and 3.06°±3.38°for the two groups.Conclusion:Combined with posterior cruciate ligament reconstruction,anatomical posterolateral corner reconstruc-tion of the popliteus tendon and open reconstruction of popliteofibular ligament showed similar out-comes.This study demonstrated that both posterolateral corner reconstruction techniques were a reliable alternative method in addressing posterolateral corner and posterior cruciate ligament insufficiency of the knee.

Objective To evaluate the early clinical outcomes of anterior cruciate ligament(ACL)reconstruction combined with anterolateral tenodesis procedure in patient with high grade pivot-shift after ACL injuries.Methods Among the 140 patients diagnosed as ACL injury and undergoing operations in our hospital between June and December 2015,18 presenting high grade pivot-shift 2+ or 3+ under anesthesia were included into this study.During their surgeries,the anterolateral tenodesis procedure using iliotibial tract ITB was applied together with ACL reconstruction.The anteroposterior stability of the knee was examined and pivot-shift test was conducted right after the operation as well as 6 and 12 months after that.The Lysholm score was used to evaluate the clinical function of their knees.Results The mean follow-up period of the 18 patients was 12.7 ± 2.4 months.There were 14 males and 4 females,with an average of 28.3 ± 7.1 years.No patients complained about unstable symptoms during the follow-up.The mean side-to-side difference of anteroposterior knee laxity assessed using KT1000 at 30 degree knee flexion was 2.3 ± 0.7 mm,which was significantly improved compared with preoperative assessment(9.2 ± 2.6 mm)(P＜0.01).For the preoperative examination,the pivot-shift examination indicated 2+ in 13 patients and 3+ in 5 patients.However,all were negative right after the operation.Seventeen patients presented negative pivot-shift at the final follow-up,while 1 had 1+ rotational laxity.Significant differences were found in the Pivot-shift test before and after the operation.The average Lysholm score improved significantly from 67.7 ± 5.9(ranging from 55 to 78)before the operation to 89.0-± 4.6(ranging from 75 to 95)after that.Conclusion The high grade pivot-shift rotational instability could be effectively restored using the anterolateral tenodesis procedure,in addition to ACL reconstruction.The early stage clinical outcomes indicate significant improvement of the knee stability postoperatively.
