ABSTRACT
Objective To observe the results and reality of transurethral resection of bladder tumor with preexcitation of electric cutting loop in the prevention of obturator nerve reflex.Methods The clinical data of 186 patients with bladder tumors admitted from January 2015 to August 2018 were retrospectively analyzed.There were 112 males and 74 females aged 35 to 83 years,average (59 ± 11)years.76 patients were admitted because of intermittent gross hematuria and 110 patients were admitted because of physical check-up.All patients underwent ultrasound,CT (plain scan/enhancement) and cystoscopy before operation.The pathological diagnosis of cystoscopy biopsy was bladder urothelial cell carcinoma.There were 105 cases clinical stage Ta stage,81 cases of T1 stage.There were 103 single cases and 39 multiple cases of non-muscular invasive bladder.According to the different surgical techniques,the patients were divided into two groups:the pre-excitation group and lateral incision group.There were 142 cases in pre-excitation group.In the pre-excitation group,the tumors were removed routinely by the resection ring.When the resection ring was far away from the tumors,the pedal switch was pressed to excite the resection ring.The resection ring was moved to the location of the tumors,and the tumors were cut to the muscular layer.The operation was completed after 2 cm electric cauterization around the wound and hemostasis.In the lateral incision group,the tumors were removed routinely by the electric resection ring.The operation time,incidence of obturator nerve reflex,incidence of bladder perforation,amount of bleeding,retention time of catheter,pathological grading,risk grading,hospitalization time and recurrence rate of tumors at 6 months after operation were compared between the two groups.Results The operation was successfully completed in both groups,and there was no transition to open operation.In the pre-excitation group,the operation time was 10 minutes to 56 minutes,with an average of (28 ± 12) minutes,and the intraoperative blood loss ranged from 5 ml to 70 ml,with an average of (35 ± 15) ml.In the lateral incision group,the operation time was 15 minutes to 65 minutes,with an average of (28 ± 11) minutes,and the blood loss was 10 ml to 80 ml,with an average of (40 ± 15) ml.There was no significant difference in operation time and blood loss between the two groups (P ＞ 0.05).There were only 3 cases of obturator nerve reflex in preexcitation group,the incidence was 2.1％.There were 13 cases of obturator nerve reflex in lateral resection group,the incidence was 29.5％.There was significant difference of nerve reflex incidence between the two groups (P ＜ 0.05).Conclusions In transurethral resection of bladder tumors,the method of pre-excitation of plasma resection ring can effectively decrease obturator nerve reflex and make the operation safer.
ABSTRACT
Objective To investigate the influence of infection factors on kidney transplantation after organ donation and possible countermeasures.Methods Thirty-seven cases of kidney transplantation in Organ Transplantation Center of Qianfoshan Hospital Affiliated to Shandong University from January 2014 to December 2016 were retrospectively analyzed.The patients were divided into two groups according to perioperative infection prevention programs:42 patients with postoperative routine use of cephalosporins or penicillin for 2 weeks,and 95 patients with postoperative application of carbapenems + micafungin.Postoperative infection rate,occurrence time,pathogen infection;donor age,perioperative pathogens of donor and receptor (organ preservation solution,drainage fluid,urine,sputum samples),acute rejection,delayed graft function (DGF),diabetes mellitus,and the use of immunosuppressive agents were recorded.Results The infection rate in carbapenem + micafungin group was 12.6％,and the infection rate in cephalosporin or penicillin group was 19.4％ (P＜0.05).Pathogen positive detection rate of the drainage fluid,urine and sputum was lower in carbapenems + micafungin group than that in cephalosporins or penicillin (P＜0.05).Within 2 weeks after operation,the detection rate of bacteria and fungi in the carbapenems +micafungin infection prevention group was lower than that in the control group (P＜0.05).There was no significant difference in the detection of viruses (P＞0.05).There were no significant differences in the detection of pathogens among the two weeks to six months after surgery (P＞ 0.05).Donor infection,acute rejection,DGF,and diabetes mellitus were the risk factors for postoperative infection (P＜0.05).Conclusion The application of carbapenems and micafungin can reduce the incidence of infection for the early stage of DCD kidney transplantation.Donor infection,acute rejection,DGF and diabetes mellitus are all risk factors for the postoperative infection.
ABSTRACT
Objective To observe the clinical efficacy and safety of second transurethral resection combined with instillation therapy and transfusion therapy of dendritic cells pulsed with tumor cells on non muscle-invasive bladder cancer.MethodsEighty patients with stage T1 non muscle-invasive bladder cancer were included in this protocol in which all patients prospectively received second transurethral resection within 4 to 6 weeks following initial resection.All 80 cases were divided into a DC group and a control group.In the DC group,dendritic cells pulsed with tumor cells were transfused between 6 -8 weeks.Bladder instillation therapy and follow-up was applied on the control group.The recurrence rate,the clinical efficacy and adverse reactions were observed and compared between the two groups.ResultsIn the initial resection,21.3％,67.5％ and 11.2％ had G1,G2 and G3 transitional cell carcinoma,respectively.Twenty-seven (33.7％) had residual tumors at the second TUR,8 patients had Ta(29.6％ ) and 19 had T1 (70.4％).After the initial TUR-Bt,residual tumors were detected in 11.1％,70.4％ and 18.5％ in G1,G2 and G3,respectively.In the 8 Ta cases,2 cases moved to a higher grade,while the grade was unchanged in 6 cases.In the 19 cases with stage T1,12 had a higher grade,5 had a lower grade and 2 remained the same.In the DC group,5 cases suffered chills and fever when dendritic cells were transfused.The fever was releaved when dexamethasone was administered.The white blood cells count,creatinine and alanine aminotransferase had no statistically significance change at pre-therapy,one year after therapy and two years after therapy (P ＞0.05).The index of CD4 、CD8 、CD4/CD8 had statistically significance change at pre-therapy,one year after therapy and two years after therapy ( P ＜ 0.05 ),while the difference between one year after therapy and two years after therapy was not statistically significance ( P ＞ 0.05 ).The first and second year recurrence rate was 2％ and 6％ in the DC group,while in the control group it was 20％ and 30％.The difference was statistically significant ( P ＜ 0.05 ).Conclusion Second transurethral resection combined with instillation therapy and transfusion therapy of dendritic cells pulsed with tumor cells could be an effective therapeutic approach to lower the recurrence rate on non muscle-invasive bladder cancer.
ABSTRACT
Objective To discuss the clinical value of dynamic monitoring the copies of human cytomegalovirus(HCMV)-DNA in prophylaxis of HCMV pneumonia after renal transplantation.Methods There were 242 cadaveric renal transplantation recipients including 144 males and 98 females,with the average age of 41(from 17 to 71).They were divided into 2 groups(experimental group 127 cases,control group 115 cases).Recipients in experimental group were routinely monitored by blood preparation and urine aliquot FQ-PCR.The therapy was initiated when HCMC-DNA>1×103 copies/ml by blood preparation and/or urine aliquot FQ-PCR with intravenous ganciclovir for 4 weeks.The dosage was calculated according to creatinine clearance rate.FQ-PCR monitoring and Preemptive therapy was not performed in the control group.The pneumonia rate, death rate and survival between the two groups were compared. Results In experimental group, the HCMV pneumonia incidence rate was 6.3 % (8/127), onset time was 46-167 d, median time was 84 d, hospitalization time was 30-57 d,median time was 36 d, death rate was 12.5 % (1/8), breathing machine using rate was 12.5 % (1/8),concurrent other pathogen infection rate was 25 % (2/8), and + year renal graft survival rate was 98.4% (125/127).One was dead with graft function and the other dysfunction was because of acute rejection.In control group, the HCMV pneumonia incidence rate was 14.8%(17/115), onset time was 34-138 d,median time was 51 d, hospitalization time was 21-67 d,median time was 40 d,breathing machine using rate was 29.4% (5/17),concurrent other pathogen infection rate was 41.2%(7/17), death rate was 23.5% (4/17), and 1 year renal graft survival rate was 93.0% (107/115).Three was dead with graft function and the other one was dead of DGF.The other 4 cases of renal dysfunction were because of acute rejection.Significant difference existed between the 2 groups (P<0.05) except for hospitalization time (P> 0.05). Conclusion The preemptive therapy of CMV pneumonia after renal transplantation by dynamic monitoring the copies of HCMV-DNA in recipients could have a good effect, and the 1 year renal graft survival rate could be higher.
ABSTRACT
Objective To summarize the experience of diagnosis and surgical treatment of long distance ureteral stenosis after kidney transplantation. Methods Eleven cases of ureteral stenosis following renal transplantation were analyzed. Ureteral stenosis happened between 2-6 months after transplantation. The clinical manifestations were as follows: serum creatinine and weight elevated,urine decreased, graft area swelling. All cases were diagnosed using ultrasound, MRU or CTU. The ureteral obstruction length was 3-7 cm. In 5 patients a Boari flap technique was used, and the native ureter for pyelo-ureterostomy was used in 2 patients. Four patients were subjected to surgical operation using the native ureter for uretero-ureterostomy. Results All of the surgical treatments were successful and no operation-related complications occurred. The operation time was 2. 5 to 4 h.After reconstruction of ureter-bladder anastomosis, the urine was increased, the serum creatinine decreased to 75-156μmol/L, and uronephrosis disappeared or alleviated. The follow-up lasting 8 to 62 months showed no recurrence in all the cases. Conclusion For such cases, ultrasound should be routinely used for the possibility of stenosis. CTU or MRU is important to know the obstruction length and position. For the patients with long distance ureteral stenosis after kidney transplantation,surgical correction is the first choice.
ABSTRACT
Objective To evaluate early diagnosis and preemptive therapy of human cytomegalovirus infection in renal transplant recipients. Methods We selected 165 renal transplant recipients who underwent transplantation from January 2007 to January 2009 and adhered to follow-up as research subjects. The samples of blood and urine were collected before transplantation, every 1 week from 2 to 8 weeks and every 2 weeks from 9 to 24 weeks after transplantation. The viral load of blood and urine was detected by fluorescence quantitative polymerase chain reaction (FQ-PCR). Once HCMV DNA load was more than 103 copies/ml, preemptive therapy was done immediately by ganciclovir. Results All the samples of blood and urine were negative before operation. HCMV DNA load could be detected in the concentrated urine at the second week and the peak of HCMV DNA loadoccurred from the sixth to eighth week after operation. At the same detection time, the number ofpositive recipients in the concentrated urine was more than in blood. In 30 cases HCMV DNA load was detected in the blood and the positive rate was 18.18%. In 64 cases HCMV DNA load was detected in the concentrated urine and the positive rate was 38.79%. The positive rate of the concentrated urine was significantly higher than in blood (P＜0.05). In 30 cases positive for HCMV DNA in the blood and urine, ganciclovir was given and the viral load was decreased gradually. But 8 recipients developed into CMV pneumonia and were cured through the comprehensive treatment. The clearance time of HCMV DNA in the concentrated urine was 10.2 ± 3.4 days. Thirty-four cases that were only positive for HCMV DNA in the urine were also treated by ganciclovir and no case developed into CMV pneumonia. The clearance time of HCMV DNA was 5.5 ± 2.1 days, and the clearance time was shortened as compared with that in those positive for HCMV DNA in the blood and urine (P＜0.05). Conclusion FQ-PCR can detect HCMV DNA in the concentrated urine in advance and increase the positive rate. Once the sample of the concentrated urine is positive, preemptive therapy has a good effect.

ABSTRACT
Objective To investigate the relationship between chronic prostatitis and the coagulase-negative staphylococci (CNS),and to study the diagnostic value and clinical significance of CNS in expressed prostatic secretion (EPS). Methods Overall,428 patients with chronic prostatitis were included in this study.Their mean age was 31 years (range,18 to 46 years).The mean cause was 6 months (range,3 to 32 months).The mean NIH-CPSI score was 23.2.Bacterial culture and antimicrobial agent sensitivity test were applied to samples from the 428 patients.The samples were taken with 4 tubes from the lower urinary tract segmented by Meares-Stamey method. Results Bacteria were found in 248 patients (57.94%) out of 428 ones.Gram-positive bacteria were found in 195 cases(78.63%).In the 195 cases,staphylococci were found in 160 cases(64.25%,160/248).CNS were found in 89 cases(35.89%,89/248),most of which were epidermidis staphylococci 81 cases(32.66%).The next were saprophytic staphylococci 3 cases and hemolytic staphylococci 2 cases.There was no correlation between NIH-CPSI score and bacterial culture results.The sensitivity test results showed the rate of drug resistance of CNS from EPS was high for ?-lactamases,quinolones and aminoglycosides(51.9% to 100%). Conclusions The results suggest that CNS is a main kind of pathogen of chronic prostatitis,so considerable attention should be paid to it.In addition,it is of significant importance to apply bacterial culture and sensitivity test in EPS to the diagnosis and treatment of chronic prostatitis.
