ABSTRACT
Objective To explore the efficacy of debridement combined with antibiotic-loaded artificial bone in the treatment of clavicular osteomyelitis.Methods The data of 45 patients with clavicle osteomyelitis admitted to Luoyang Orthopedic Hospital(Henan Orthopedic Hospital)in Henan Province from January 2012 to June 2022 were retrospectively analyzed.They were divided into treatment group(n = 24)treated with debridement combined with antibiotic-loaded artificial bone,and control group(n = 21)treated with debridement.We compared the operation time,the duration of drainage tube placement,wound healing time,white blood cells(WBC),C-reactive protein(CRP),and erythrocyte sedimentation rate(ESR)in the two groups.Preoperative visual analog scores(VAS)and VAS 1 month after operation,and preoperative Constant-Murley score(CMS)and CMS 12 months after operation were observed.Infections,recurrence and complications in the two groups were recorded in the follow-up.Results All the 45 patients completed the surgery successfully and were followed up for 13 to 35 months,with an average of(23.53±5.11)months.The operation time and the duration of drainage tube place-ment of the treatment group were longer than those of the control group(P<0.05),and there was no significant difference in the wound healing time(P>0.05);preoperative and 14-day postoperative WBC,CRP,and ESR,VAS 1 month after operation,and CMS 12 months after operation were all significantly improved in the two groups.The differences were all statistically significant(P<0.05),and the CMS of the treatment group was higher than that of the control group(P<0.05).During the follow-up,there were less cases of infection recurrence in the treatment group when compared with that in the control group(2/24,8.33%vs.5/21,23.81%).There were 2 cases of aseptic exudation in the treatment group.There were 1 case of bone defect in the treatment group and 5 in the control group,all of which had healed after the second-stage iliac implantation,and the rest did not have the complication of aseptic exudation,bone defects and pathologic fracture.Conclusion Debridement and antibiotic-loaded artificial bone can effectively control the infection and preserve the shape and function of the clavicle,with a low recurrence rate of postoperative infection,simple surgical operation,and no serious complications.It is wor-thy of clinical promotion.
ABSTRACT
Objective To assess the gender-related differences of upper tract urothelial carcinoma and analyze the causes of the gender-related differences.Methods We retrospectively studied 942 patients underwent radical nephroureterectomy for upper tract urothelial carcinoma between January 2000 and December 2014 in our hospital.The mean age of the entire cohort was 64.5 years,with 424 males (45.0％)and518 females (55.0％).Compared with male patients,female patients tended to had a history of aristolochic acids exposure (5.2％ vs.11.1％,P =0.001),infrequent smoking (29.7％ vs.5.2％,P ＜0.001) and showed poorer renal function (P =0.023).We reviewed clinicopathologic data from these patients and used univariate analysis to determine the gender-related differences.The Kaplan-Meier method was adopted to investigate the gender differences of cancer specific survival,bladder recurrence-free survival and contralateral upper tract recurrence-free survival of patients.Results When compared with males,females were less likely to have high-stage disease (33.7％ vs.24.9％,P =0.003).The mean follow-up for the entire cohort was 70.2 months (4-193 months).The cancer specific survival rate (x2 =14.116,P ＜0.001)and the contralateral upper urinary tract recurrence rate(x2 =7.362,P =0.007)in females were both higher than those in males.The 5-year cancer specific survival rates were 72.0％ in the males and 83.5％ in females,respectively.In addition,the 5-year contralateral UTUC-free survival rates were 98.6％ in the males and 92.9％ in females.Conclusions Female patients in our cohort were more common and they were more likely to be exposed to aristolochic acids.Females were less likely to have high-stage disease but had significantly worse contralateral upper tract recurrence-free survival.
ABSTRACT
Objective:To evaluate the clinical effect of retroperitoneoscopic renal pedicle lymphatic disconnection via extra-adipose capsule in the management of chyluria and to discuss the management of its complications.Methods:From August 2013 to June 2008,five patients with chyluria were admitted. All the patients were female,aged from 26 to 73 years,and disease course from 1 to 10 years.All the five patients had complained of intermittently voiding milky urine with varying degrees of weight loss,and fa-tigue,of whom two presented with flank pain and one with anemia.Their urine chyle tests were con-firmed to be positive.Preoperative cystoscopy found that chyluria was from the left side in 3 cases,and from the right side in 2 cases.Their proteinuria ranged from +to ++++.All the cases had been treated with the modified procedure by which lymphatic ligation was performed to hilar vessels and proximalureter via extra-adiposecapsule without disconnection of perirenal fat tissues.The operation time,intraoperative blood loss,postoperative intestinal function recovery,catheter time,drainage tube removal time and com-plications during operation were collected.Results:All the five cases were performed successfully.The operation time ranged from 75 to 170 minutes,mean (126.0 ±39.6)minutes,with the intraoperative blood loss 20 to 60 mL,mean (38.0 ±16.4)mL,and the postoperative intestinal function recovery time 1 to 3 days,mean (1.9 ±0.4)days.The catheter time was 1 to 4 days,mean (2.1 ±0.3)days and the drainage tube removal time ranged from 3 to 15 days,mean (9.3 ±1.8)days.Postoperatively lym-phorrhagia was found in two cases.No renal vessels injury occurred during operation.Chyluria of all the patients disappeared on the operation day with negative chyluria test after surgery.Furthermore,urine test revealed that proteinuria was totally negative.No recurrence was detected in our patients in the 9 to 31 months’follow-up.Conclusion:This modified procedure does not have to disconnect perirenal fat tissues and nephropexy during operation.It was characterized with shorter operation time,definitive effect and fewer complications.
ABSTRACT
Objective To report a ileal ureteric replacement surgery for bilateral long segment ureter injury.Methods Data from a patient suffered bilateral long segment uretercic stenosis was reviewed.A 32-year-old female,who underwent radical surgery of cervical cancer and postoperative radiotherapy 1 year ago,complained intermittent low back pain for 11 months and was found renal function abnormality for 3 months.Ultrasound showed bilateral hydronephrosis,and the CT urography showed bilateral middle-lower ureteral stenosis.Preoperative diagnosis was bilateral hydronephrosis with bilateral ureteral obstruction.The patient underwent bilateral ileal ureteric replacement under general anesthesia.Results The surgical procedure was successful and the postoperative recovery was favorable.The operation time was 180 min,and blood loss was 100 ml.The abdominal cavity drainage tube was removed 8 days and the urinary catheter was removed 9 days postoperatively.During 8 months' follow up,the patient showed resolved flank pain with stable serum creatinine.No complication was reported.The CTU 2 months postoperatively showed the hydronephrosis was relieved with normal functioning kidneys.Conclusion Bilateral ileal ureteric replacement surgery might be an effective procedure and viable option for bilateral long segment ureteric injuries.
