ABSTRACT
Objective:To explore the application value of enhanced recovery after surgery (ERAS) in laparoscopic radical resection of bladder cancer and ileal bladder surgery under modular operation procedures.Methods:A retrospective selection of 42 cases of laparoscopic radical radical resection of bladder cancer and ileal bladder surgery performed by the Department of Urology, General Hospital of Southern Theater Command from January 2017 to December 2019 were divided into two groups according to the different management methods adopted during the perioperative period: ERAS management group and conventional management group, each with 21 cases. Among them, patients in the ERAS management group were managed by ERAS during the perioperative period, and patients in the conventional management group were managed by conventional management during the perioperative period. The postoperative hospital stay, first exhaust time, first defecation time, first time to get out of bed, first liquid food time, postoperative visual analogue scale (VAS) score, as well as transferrin, upper arm circumference, body mass index, plasma albumin, total protein, and total protein were compared between the two groups of patients after surgery. The measurement data conforming to the normal distribution were expressed as mean±standard deviation ( Mean± SD), and the in dependent t-test was used for comparison between groups; the measurement data of non-normal distribution were expressed as the median (interquartile range) [ M( P25, P75)], the independent sample Mann-Whitney U test was used for comparison between groups; the Chi-square test was used for comparison of enumeration data between groups. Results:The postoperative hospital stay in the ERAS group was (8.9±1.8) d, the first exhaust time was (33.4±3.2) h, the first defecation time was (60.3±7.8) h, the first time to get out of bed was (23.1±6.7) h, the first liquid food time was (82.7±18.5) h and postoperative VAS was (1.3±0.6), that were significantly reduced compared with the conventional treatment group [(12.3±2.3) d, (51.4±5.2) h, (73.0±8.1) h, (34.7±8.2) h, (109.7±21.6) h, (3.6±0.8)], the difference were statistically significant ( P<0.05). In the ERAS group, the decreased value of transferrin was [0.8 (-0.4, 2.2) g/L], the decreased value of body mass index was[1.61±0.73], the decreased value of plasma albumin was [3.5±1.5 g/L], the decrease value of total protein was[10.1±5.6 g/L] and the decrease value of prealbumin was [90.5±11.3 mg/L] were significantly lower than those of the conventional management group[(1.9(0.9, 3.6) g/L, (2.32±1.05) kg/m 2, (9.6±2.0) g/L, (16.3±4.9) g/L, (131.3±7.4) g/L], and the difference were statistically significant ( P<0.05). Conclusion:Modular laparoscopic precision resection of bladder cancer and ERAS concept after ileal bladder surgery is beneficial to shorten the hospital stay, reduce postoperative pain, have less impact on the patient′s body loss and immune function, and can speed up the patient′s postoperative recovery.
ABSTRACT
Objective:Bioinformatics was used to analyze the gene expression profile of renal chromophobe cell carcinoma (RCCC) to find out the key genes of RCCC.Methods:Chromophobe renal cell carcinoma gene chip data GSE15641 and GSE11151 were downloaded from the GEO database. Using R software packages such as " Affy" and " limma" in R software to screen differentially expressed genes, combining with David and STRING online bioinformatics tools to analyze the regulatory network of differentially expressed genes and construct protein-protein interaction (PPI) network, the Hub gene was screened through the Cytohubba plug-in of Cytoscape software.Results:A total of 261 differentially expressed genes were screened, including 194 down-regulated genes and 67 up-regulated genes. Gene enrichment (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to explore their biological functions. In GO enrichment analysis, biological processes were mainly enriched in cell secretion, gluconeogenesis and cell proliferation regulation; in cell composition, they were mainly enriched in exosomes, plasma membranes and their components; in molecular function, they were mainly enriched in heparin binding; in KEGG pathway analysis, they were mainly enriched in metabolic pathway, antibody biosynthesis pathway and renin angiotensin system pathway. PPI network was constructed by using online bioinformatics tools. The top 10 Hub genes were screened by using cytohubba plug-in in Cytoscape software, which were pipecolic acid and sarcosine oxidase (PIPOX), hydroxyacid oxidase 2 (HAO2), kynurenine 3-monooxygenase (KMO), solute carrier family 2 member 2 (SLC2A2), formimidoyltransferase cyclodeaminase (FTCD), angiogenin (ANG), APOBEC1 complementation factor (A1CF), aldehyde dehydrogenase 8 family member A1 (ALDH8A1), vitamin D binding protein (GC), histidine rich glycoprotein (HRG).Conclusions:Bioinformatics analysis of differentially expressed genes in renal chromophobe cell carcinoma can effectively explore the interaction information of these differentially expressed genes, and provide new ideas for the treatment of renal chromophobe cell carcinoma.
ABSTRACT
Objective:To determine the efficacy and safety of sacral neuromodulation (SNM) in incomplete spinal cord injured (SCI) subjects affected by neurogenic lower urinary tract symptoms.Methods:Clinical data of 36 patients with incomplete spinal cord injury who underwent SNM from February 2015 to April 2019 were retrospectively analyzed and were divided into group NUR (16 cases neurogenic urinary retention group) and group NOAB (20 cases of neurogenic bladder overactive group). If at least 50% clinical improvement occurred, the patient would undergo a permanent SNM procedure. The patients were evaluated by using bladder diary, postvoid residual volume measurement, frequency of clean catheterization and urodynamic parameters before and during the test, and after the permanent SNM.Results:Among the 36 patients, 21 cases (58.3%) were tested effectively and received permanent stimulator implantation, 7(19.4%) in NUR group and 14(38.9%) in NOAB group. The residual urine volume of bladder, the average number of catheterization and the average number of urination in NUR group were improved in different degrees. After operation, the symptoms of frequent urination, urgency of urination and incontinence in NOAB group were relieved to varying degrees. During the follow-up, 2 patients with urinary retention failed the treatment. After the Ⅰ phase of the contralateral S3, the curative effect was recovered. A patient were infected after operation, and the wound healed after removal of the infection.Conclusions:The SNM is safe and effective in the treatment of neurogenic lower urinary tract symptoms in some incomplete spinal cord injury patients, and is helpful to protect renal function in patients with spinal cord injury. SNM can not improve all symptoms at times, but the SNM can be considered in patients with ineffective or intolerant traditional treatment.

ABSTRACT
<p><b>OBJECTIVE</b>To evaluate safety and efficacy of conversion of calcineurin inhibitors (CNI) to sirolimus (SRL) therapy for treatment of new-onset diabetes after kidney transplantation (NODAT).</p><p><b>METHODS</b>Of 321 kidney transplant recipients, 34 patients who developed NODAT (10.59%) were divided into 3 groups to receive continued CNI therapy at a reduced dose (group A, 14 cases), sirolimus conversion therapy (group B, 12 cases), or oral hypoglycemic drugs (group C, 12 cases). All the patients had dietary and exercise therapies, and insulin injections were given in patients with postprandial (2 h) blood glucose over 14.0 mmol/L. The patients were followed up regularly for 5 years.</p><p><b>RESULTS</b>The mean blood glucose level was 13.02∓1.74 mol/L upon the diagnosis of NODAT in the 34 patients without significant differences between the 3 groups. At 6 months of therapy, fasting plasma glucose levels in the 3 groups decreased to 8.05 ∓2.45, 7.45∓2.44, and 9.30∓3.89 mmol/L, repsectively; at 12 months, blood glucose became normal in both groups A and B, but the patients in group A needed a greater daily insulin dose (P<0.05). In group B, the mean serum creatinine level was 165.1∓61.82 mmol/L at the conversion and lowered to 150∓53.05 mmol/L at 5 years (P<0.05), which were similar to those in group A at the two time points (152∓43.05 and 145.88∓53.05 mmol/L, respectively; P>0.05). In group C, creatinine level further increased after medication with oral hypoglycemic drugs. At 5 years, the patient and graft survival rates were 100% and 75% in group A, respectively, similar to those in group B (83.4% and 68%, respectively; P>0.05); group C showed lower patient and graft survival rates than groups B and C.</p><p><b>CONCLUSION</b>Conversion from CNI to SLR therapy can significantly the metabolism of patients with NODAT without increasing the risk of acute graft rejection.</p>

Objective To assess the effect of alprostadil on accelerating early recovery of renal transplant patients with delayed graft function.Methods A randomized control clinical trial was designed in renal recipients with delayed graft function(DGF)who were administered with 50μg alprostadil each day after the operation.The effects of alprostadil were compared with the control group which included 14 recipients with DGF to determine the influences of alprostadil on urine,serum creatinine(SCr).Under Doppler ultrasound,the renal blood flow resistance-indexes(RI)were measured.The rates of acute renal graft rejection(AR)were also calculated in both groups,and the 1year patient/graft survival rates were compared between the two groups.Results Urine was significantly higher in alprostadil-treated group than in control group(P ＜ 0.05).On the contrary,SCr and RI were significantly lower in alprostadil-treated group than in control group(P ＜ 0.05).No significant differences were found between the two groups in AR rate(6.25％ vs 7.14％)and the 1-year patient/graft survival rates(P ＞ 0.05).Conclusion The application of alprostadil in renal recipients with DGF had beneficial effects on accelerating recovery of renal graft function.
ABSTRACT
Objective To analyze the effect of antibiotic treatment on prostate specific antigen (PSA) derivations in patients with and without prostate cancer and to further determine if the changes of PSA values after antibiotic treatment could help to exclude inflammation in the differential diagnosis of an abnormal PSA.MethodsA total of 100 patients with lower urinary tract symptoms,a PSA level of 4 to 10 μg/L,free PSA/total PSA (fPSA/tPSA) ratio ＜ 0.25,and a negative digital rectal examination and transrectal ultrasonography were enrolled in this study.All patients received 500 mg of ciprofloxacin twice a day for 3 weeks.Free and total PSA values were measured before and after antibiotic treatment.All the patients were then scheduled for 12-core prostate biopsy.Results The mean tPSA value was (6.5 ± 1.2) and (5.1 ± 1.2) μg/L respectively before and after antibiotic treatment ( P ＜ 0.01 ).Ninety-one patients (91.0％) showed tPSA reduction after antibiotic therapy,of which 13 ( 14.3％ ) had prostate cancer on biopsy.In 17 cases (18.7％) post-treatment tPSA was less than 4 μg/L.Three of the 17 cases (17.6％)had prostate cancer on biopsy.In 6 of the 100 men post-treatment tPSA was between 4 and 10 μg/L and the fPSA/tPSA ratio was above 0.25.One of these cases had prostate cancer on biopsy.Seven cases had a ＞50％ reduction in PSA levels with no positive biopsy results.Although mean total PSA and PSAD decreased after treatment in both groups,the reductions within these parameters were not significantly different between patients with and without prostate cancer (P ＞ 0.05).Furthermore,no differences emerged in terms of the changes of other PSA derivations including fPSA and fPSA/tPSA ( P ＞ 0.05 ).ConclusionsThe PSA levels may change with long-term antibiotic treatment in patients with elevated PSA values.A decrease in PSA after antibiotic treatment does not rule out the presence of prostate cancer even if PSA decreases to a normal level.But a ＞ 50％ reduction in PSA levels may be associated with a decreasing risk of prostate cancer,which may allow a postponement of prostate biopsy in selected patients.
ABSTRACT
OBJECTIVE: Complication incidence of urinary fistula which frequently occurs following renal transplantation is 3%-10%. Thus, poor processing may cause loss of transplanted kidney. This study was designed to retrospectively analyze urinary fistula following renal transplantation and to summarize the processing experience. METHODS: A total of 27 out of 1 203 patients with urinary fistula following renal transplantation (16 males and female 11 and mean age of 43 years) were collected from Guangzhou General Hospital of Guangzhou Military Command of Chinese PLA from December 2000 to March 2009. Totally, 26 patients accepted donor kidney from corpse, and 1 from living body. All patients were treated with expectant treatment (n=17) including inserting 18Fr Foley catheter alone and draining from the native drainage channel of operative site (n=12) and inserting a ureteral stent (single-J) by cystoscope retrograde approach and inserting 18Fr Foley catheter into the bladder (n=5); exploring operation (n=10) including anastomosing ureter and bladder and placing ureteral stent (n=5) and anastomosing ureter and ureter of recipient and placing ureteral stent (n=5); pedicled omentum grafts to cover and surround stoma after suturing (n=6). RESULTS: Only 1 case was failed because kidney vain was injured in the second operation and the kidney was resected. Another 26 cases were cured. Within the 3 month to 7 years follow-up, the urinary fistulas did not relapse, no stegnosis or hydronephrosis, no urinary tract infection and renal function were normal. CONCLUSION: Rapid diagnosis and treatment for urinary fistulas after renal transplantation is imperative. First mostly patients may be cured by expectant treatment. If not then perform exploratory operation. Using peclicled omentum grafts to cover and surround stoma after suturing for complex urinary fistulas can raise achievement ratio of operation.
ABSTRACT
Objective To summarize the success of congenital penile curvature. Methods 401 cases of con-genital penile curvature,whose average age is 2. 5 years ,ranging from 1 year to 26 years old. Of all cases ,383 patients who have both hypespadias and penile cun, ature, only 18 patients are congenital penile curvatures. 295 paitents are slight curvature,85 patients are moderate curvature and 21 patients are severe curvature. Curvature correction was per-formed on a case-by-case basis by solution fibric trabs of ventrial urethra and surrounding,skin de-gloving, ff necessa-ry,dorsal plication,and confirmed by Gittes test. Results . Curvature correction was possible by mobilization of ure-thra after penile degloviag,only a few need dorsal plieation. Followup for 6 months to 2 years,396 patients are success at once. The others after a second surgery had 100% success. Conclusions Solution fibrie trabs of ventrial urethra and surrounding, skin de-gloving, if necessary,dorsal plication ,is the first choice to repair of the congenital penile cur-vature and have good results.
ABSTRACT
Objective To determine whether an increased number of transrectal biopsy cores improves the accuracy of biopsy Gleason score. Methods This study reviewed a total of 86 patients who were diagnosed as prostate cancer by transrectal needle biopsy and subsequently underwent radical prostatectomy (RP) without neoadjuvant therapy.The rate of grading concordance between biopsy and RP specimens was analyzed by dividing these patients into 2 groups according to the biopsy cores:group A,46 patients who underwent transrectai biopsy sampling of 6 cores,and group B,40 patients who underwent biopsy sampling of 13 cores. Results The concordance between prostate biopsy and radical prostatectomy Gleason score was 65.0%and 34.8% for 13 core and 6 core biopsy,respectirely (P＜0.05).Furthermore,these findings tended to be more prominent as the biopsy Gleason score was lower.Multivariate analysis identified the number of biopsy cores and percent of positive biopsy cores as independent predictors of accurate Gleason grading regardless of other parameters examined in this study. Conclusion Extended needle biopsy may increases the accuracy of biopsy Gleason score for assessing final prostate cancer grade.
