Objective To investigate the causes of postoperative severe infection and other complications of percutaneous nephrolithotomy,and to study the principles of prevention and treatment.Methods Five hundred and sixty three cases of patients underwent percutaneous nephrolithotomy from September 2008 to December 2011 in our hospital,after operation,22 patients were found with serious infection.Data of these 22 cases were analyzed retrospectively according to the causes of the infection,corresponding prevention and treatment.Results The occurrence rate of severe postoperative infection was 3.9％ ( 22/563 ) in this group.The condition of 21 patients improved through adjusting antibiotics and taking other necessary measures in time;the condition of 1 case of septic shock patient was under control by giving anti-infective and anti-shock treatment measures.Conclusion Percutaneous nephrolithotomy is a safe and effective minimally invasive surgery,with a certain incidence of postoperative infection which should be timely and effectively controlled.

Objective To discuss the prevention and management of complications of transurethral electrovaporization of the prostate(TUVP).Methods A total of 820 patients underwent TUVP from June 1998 to August 2005.A Wolf electrovaporization system and a F_(24) 12? resectoscope were used.After the seminal colliculus was identified for making a reference plane,the prostatic tissues were removed untill the surgical envelope,and the bladder neck and the apex of prostate were surgically shaped.Results Complications occurred in 124 patients(15.1%,124/820).There were 17 cases of intraoperative complications(2.0%),including massive haemorrhage in 6 patients(0.7%),presymptoms of transurethral resection syndrome in 6 patients(0.7%),and perforation on the juncture of the bladder and the prostate in 5 patients(0.6%).There were 107 cases of postoperative complications(13.0%), including urethral stricture in 18 patients(2.2%),spasm of the bladder in 32 patients(3.9%),secondary hemorrhage in 3 patients(0.4%),retrograde ejaculation in 11 patients(1.3%),temporary incontinence in 13 patients(1.6%),infection of the urinary tract in 24 patients(2.9%),and acute pulmonary thromboembolism in 6 patients(0.7%). Conclusions Preoperative precautions and clear intraoperative exposure are essential to prevent the incidence of complications of TUVP.

Objective To discuss the causes and management of the complications of the transurethral electrovaporization of prostate(TVP) to improve the effect.Methods All 820 cases took TVP.3～6 months follow-up was taken to investigate the complications and their disposal.Results No patient died,6 cases had massive haemorrhage during operation,6 cases had presymptom of TUR syndrome,5 cases had perforation of juncture of bladder and prostate,6 cases had acute pulmonary thromboembolism(PTE) after TVP,32 cases had spasm of bladder,18 cases had urethral stricture,3 caess had postoperative bleed,11 cases had retrograde ejaculation,13 cases had temporary incontinence,24 cases had infection of urinary tract.Conclusion Pre-operational precautions are essential,the complications of TVP may be decreased by accurate operation and reliable management of infection.

Objective To investigate the expressions of survivin and bcl-2 and their relationships in transitional cell carcinoma of the bladder.Methods The expressions of survivin and bcl-2 in 40 cases of transitional cell carcinoma of the bladder were detected with streptavidin-biotin peroxidase(SP) method,with 15 cases of normal bladder specimens as controls.Results Survivin was expressed in 25 of 40(58.149%) cases of bladder carcinoma tissues,and normal bladder specimens did not express survivin(P

Objective:To analyze the effect of levonorgestrel releasing intrauterine system ( Mirena) on endometrium in the pa-tients with anovulatory uterine bleeding. Methods:Totally 67 cases of anovulatory uterine hemorrhage were treated with Mirena. The menstrual blood volume, uterine endometrial thickness, hemoglobin, endometrial ET content and complications were recorded before and after the treatment. Results:After the 12-month treatment, the menstrual blood volume and endometrial thickness were significant-ly decreased, and hemoglobin was significantly increased (P<0. 01). The percentage of abnormal uterine bleeding was significantly decreased, the ET content in endometrium was significantly decreased (P<0.05), and the ET content was decreased significantly with the prolongation of the treatment time. The complication rate was reduced from 50. 74% to 7. 46%. Conclusion:Mirena is nota-bly effective in the treatment of the patients with anovulatory uterine bleeding.

Objective To retrospec the efficacy of percutaneous nephrolithotomy on treatment of urinary tract stones in solitary kidney.Methods From June 2008 to April 2011,percutaneous nephrolithotomy technique was used to treat 20 cases of urinary tract stones,with kidney stone or cast form staghorn calculi in 4 cases,single pelvis,calyceal stones 10 cases,6 cases of upper ureteral calculi;Fourteen cases used the standard channel F24;6 cases used F16 Micro Channel.Among the 20 patients,16 cases performed stage Ⅰ single channel surgery;2 cases performed dual-channel surgery in Ⅰ stage;2 patients with severe infection performed stage Ⅱ single channel surgery.Results The average duration of the operation was 66mins.The stone clearance rate was 88.36％ on average(18/20),without laceration or bleeding of pelvis or renal calyces mucosa or any other complications.Postoperative indwelling nephrostomy tubes were removed 6 -7 days later,without complications found during the follow-up period.For the 6 cases with preoperative renal dysfunction before surgery,the levels of blood Cr decreased at 2 weeks after surgery.Conclusion Compared to open surgery,percutaneous nephrolithotomy is safe and effective with small wound in treatment of solitary kidney with invasive upper urinary tract calculi.

Objective To investigate the protective effects of G CSF on lungs of rats with acute cholangitis and changes in blood TNF and TXA 2/PGI 2 by treating the rats with G CSF. Methods Seventy two Wistar rats were randomized into the control, infected and treated groups. We established the model of cholangitis in the rats with injection of E. coli 25922 into the bile duct. The animals in the treated group were pretreated with G CSF 500 ng/day bid) for 5 days before the E. coli injection. The levels of blood TNF and TXA 2/PGI 2 were measured at the 3rd, 6th and 12th h after the injection. Meanwhile, the morphological changes in lungs of the rats were observed. Results The morphological changes in lungs were milder and levels of blood TNF and TXA 2/PGI 2 were significantly lower in the treated group than in the infected one (P

OBJECTIVE:To provide reference for rational use of human serum albumin for surgical inpatients. METHODS:The utilization of human serum albumin for surgical inpatients in a hospital during Jan.-Mar. 2014 was analyzed and evaluated by UHC Guidelines for the Use of Album,Nonprotein Colloid,and Crystalloid Solutions(2010 edition)and European Immune Globu-lin and Albumin Use Recommendation. RESULTS:Among the 556 patients,totally 895 human serum albumin application were con-ducted,mainly involving development of gastrointestinal surgery(29.7%),hepatobiliary surgery(25.9%)and cardiothoracic sur-gery(13.1%). The main reasons were correcting hypoalbuminemia(62.9%),followed by albumin supplemented during major sur-gery(7.9%)and alleviating ascites in patients with cirrhosis(4.4%);only 95 applications(10.6%)were considered appropriate. The most prevalent inappropriate reason was for correcting hypoalbuminemia. CONCLUSIONS:Human serum albumin in the surgi-cal inpatients in the hospital shows a large amount,and low consistent rate between indications and guidelines. The rational stan-dardized utilization of human serum albumin should be strengthened.

Objective To investigate the relationship between the incidence of dysphagia and the location of brain lesions in patients with acute stroke.Methods Swallowing function was assessed by Watin drinking water test within 48 hours after admission in 226 cases with acute stroke.The location of the brain lesions was identified by CT and / or MRI.According to the US National Institutes of Health Stroke Scale (NIHSS),evaluation of nerve functions was evaluated within 24 hours after admission in stroke patients.Results The incidence of dysphagia was 50.4％ (114 /226) in 226 patients in acute stage.The degree of neurological deficit of stroke patients on admission was significantly correlated with the occurrence of dysphagia (x2 =13.35,P=0.02).The incidence of dysphagia caused by lesions in internal carotid artery trunk (hemisphere in combination with basal ganglia/internal capsule) was more common in anterior circulating territory(internal carotid artery system),dysphagia with internal carotid arterg(ICA) trunk occlusion (hemisphere in combination with basal ganglia/internal capsule) was more common than that caused by cortex branches occlusion (hemisphere-cortex) or penetrating ICA injuries (basal ganglia/internal capsule) and cortex branches occlusion (hemisphere-cortex),respectively(x2 =8.228,P＜0.05).The incidences of dysphagia induced by brain lesions of different cortex lobes had no statistic differences(x2 =0.312,P＞0.05).In posterior circulating territory (vertebro-basilar system),the incidence of swallowing disorders was significantly higher in brain stem group than in the thalamus and cerebellum (x2 =27.292,P＜0.001).The incidence of the dysphagia caused by lesions in cerebral hemispheres,combined basal ganglia / internal capsule and brain stem lesions were significantly higher than those caused by other lesions(x2 =35.639,P＜0.000).Conclusions Brain lesions of hemisphere combined basal ganglia/internal capsule and brain stem are significantly associated with the occurrence of dysphagia after acute stroke.
