OBJECTIVE: To study the clinical features of vesicoureteral reflux (VUR) in children with neurogenic bladder (NB), and to provide a reference for its early diagnosis and treatment. METHODS: Clinical data were collected from 26 children with NB and urinary tract infection who were admitted to the Department of Pediatric Nephrology from January 2014 to December 2019. According to the presence or absence of VUR, the children were divided into a VUR group with 11 children and a non-VUR group with 15 children. Clinical features were compared between the two groups. RESULTS: Compared with the non-VUR group, the VUR group had a significantly higher proportion of children with non- CONCLUSIONS When NB children have the clinical manifestations of non-

OBJECTIVES: Urinary tract infection (UTI) is the most common infection complication after kidney transplantation, and the reports of the incidence vary greatly among different centers. This study aims to explore the risk factors for UTI after kidney transplantation with the donation from brain death (DBD) and the impact on graft function, thus to provide theoretical basis for comprehensive prevention and treatment of UTI after kidney transplantation. METHODS: The clinical and laboratory data of DBD kidney transplantation from January 2017 to December 2018 in Xiangya Hospital, Central South University were collected and retrospectively analyzed. Patients were assigned into an UTI group and a non-UTI group. The base line characteristics, post-transplant complications, and graft function were compared between the 2 groups. Multivariate logistic regression was used to analyze the risk factors for UTI. RESULTS: A total of 212 DBD kidney transplant recipients were enrolled in this study. UTI occurred in 44 (20.75%) patients after transplantation. The female, the time of indwelling catheter, and postoperative urinary fistula were independent risk factors for UTI after DBD kidney transplantation. A total of 19 strains of gram-positive bacteria, 12 strains of gram-negative bacteria , and 10 strains of fungi were isolated from the urine of 44 UTI patients. The UTI after kidney transplantation significantly increased time of hospital stay ( CONCLUSIONS UTI after DBD kidney transplantation transplantation affects the renal function at 3 months and increases the patient's economic burden.

PURPOSE: Urosepsis in adults comprises approximately 25% of all sepsis cases, and is due to complicated urinary tract infections in most cases. However, its mechanism is not fully clarified. Urosepsis is a very complicated disease with no effective strategy for early diagnosis and treatment. This study aimed to identify possible target-related proteins involved in urosepsis using proteomics and establish possible networks using bioinformatics. METHODS: Fifty patients admitted to the Urology Unit of Lanzhou General PLA (Lanzhou, China), from October 2012 to October 2015, were enrolled in this study. The patients were further divided into shock and matched-pair non-shock groups. 2-DE technique, mass spectrometry and database search were used to detect differentially expressed proteins in serum from the two groups. RESULTS: Six proteins were found at higher levels in the shock group compared with non-shock individuals, including serum amyloid A-1 protein (SAA1), apolipoprotein L1 (APOL1), ceruloplasmin (CP), haptoglobin (HP), antithrombin-III (SERPINC1) and prothrombin (F2), while three proteins showed lower levels, including serotransferrin (TF), transthyretin (TTR) and alpha-2-macroglobulin (A2M). CONCLUSION Nine proteins were differentially expressed between uroseptic patients (non-shock groups) and severe uroseptic patients (shock groups), compared with non-shock groups, serum SAA1, APOL1,CP, HP, SERPINC1and F2 at higher levels, while TF, TTR and A2M at lower levels in shock groups.these proteins were mainly involved in platelet activation, signaling and aggregation, acute phase protein pathway, lipid homeostasis, and iron ion transport, deserve further research as potential candidates for early diagnosis and treatment. (The conclusion seems too simple and vague, please re-write it. You may focus at what proteins have been expressed and introduce more detail about its significance.).

Objective: To compare thulium laser vaporization of the prostate (TLVP) and transurethral resection of the prostate (TURP) in the treatment of benign prostate hyperplasia (BPH) analyze the risk factors for postoperative urethral stricture. METHODS: From June 2015 to June 2016, 210 BPH patients in our hospital underwent TURP (n = 126) or TLVP (n = 84). We followed up the patients for 6 months, compared the effects of the two surgical strategies and analyzed the risk factors for postoperative urethral stricture by multivariate logistic regression analysis. RESULTS: Compared with TURP, TLVP achieved significantly shorter time of operation (［78.6 ± 27.5］ vs ［53.2 ± 21.6］ min, P <0.01), postoperative bladder irrigation (［31.5 ± 2.9］ vs ［26.1 ± 3.7］ h, P <0.01), urethral catheterization (［5.3 ± 1.7］ vs ［3.7 ± 1.5］ d, P <0.01) and postoperative hospitalization (［7.9 ± 2.1］ vs ［5.5 ± 1.4］ d, P <0.01) as well as lower urinary leukocyte count at 6 months after surgery (［32.1 ± 12.6］ vs ［24.9 ± 11.7］ /μl, P <0.01) and incidence rate of postoperative complications (11.9% ［15/126］ vs 3.6% ［3/84］, P <0.05), particularly that of urethral stricture (7.9% ［10/126］ vs 1.2% ［1/84］, P <0.05). Logistic regression analysis showed that the preoperative urinary leukocyte count, postoperative urethral catheterization time, and surgical method were independent risk factors for postoperative urethral stricture. CONCLUSIONS TLVP, in comparison with TURP, has the advantages of definite effect, fast recovery, high safety and low incidence of postoperative urethral stricture. The main risk factors for postoperative urethral stricture include preoperative urinary tract infection, postoperative urethral catheterization time and surgical method.

Objective: To explore the feasibility and effectiveness of "one-puncture one-needle" transrectal ultrasound (TRUS)-guided prostate biopsy in the prevention of postoperative infections. METHODS: We retrospectively analyzed the clinical data about "one-puncture one-needle" (the observation group) and "one-person one-needle" (the control group) TRUS-guided prostate biopsy performed in the Second People's Hospital of Guangdong Province from January 2005 to December 2015, and compared the incidence rates of puncture-related infection between the two strategies. By "one-puncture one-needle", one needle was used for one biopsy puncture, while by "one-person one-needle", one needle was used for all biopsy punctures in one patient and the needle was sterilized with iodophor after each puncture. RESULTS: Totally, 120 patients received 6+1-core or 12+1-core "one-person one-needle" and 466 underwent 12+1-core "one-puncture one-needle" TRUS-guided prostate biopsy. There were no statistically significant differences between the two groups of patients in age, the prostate volume, the serum PSA level, or the detection rate of prostate cancer (P >0.05). Compared with the control group, the observation group showed remarkably lower incidence rates of puncture-related urinary tract infection (7.5% vs 0.9%, P <0.05), fever (5.0% vs 1.1%, P <0.05), bacteriuria (2.5% vs 0.2%, P <0.05), and total infections (16.7% vs 2.6%, P<0.05) postoperatively. Two cases of bacteremia or sepsis were found in each of the groups, with no significant difference between the two. CONCLUSIONS "One-puncture one-needle" TRUS-guided prostate biopsy can effectively prevent puncture-related infections.

Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

To evaluate the efficacy and safety of modified pedicle subtraction osteotomy for treatment of thoracolumbar old fracture with kyphosis.
 Methods: From January 2003 to January 2013, 58 patients of thoracolumbar kyphosis, who underwent modified pedicle subtraction osteotomy, were reviewed. Among them, 45 cases underwent initial operation and 13 cases underwent revision surgery. Preoperative and postoperative kyphotic Cobb's angle, score of back pain, as well as the incidence of complication were accessed by using visual analogue scale (VAS) and Oswestry disability index (ODI).
 Results: Mean follow-up duration was 42 months (range, 24-60 months). Average operative time was 258 min (range, 190-430 min), while average bleeding was 950 mL (range, 600-1 600 mL). All the patients were significantly improved in function and self-image, and achieved kyphosis correction with 17.9°± 4.3°. VAS of low back pain was decreased by 3.1±0.6; ODI was dropped by 25.3%±5.5%. 3 patients (5.2%) suffered anterior thigh numbness and got recovery after 3 months of follow-up. Complications happened in 19 patients, including 12 with cerebrospinal fluid leak, 4 with superficial wound infection, and 3 with urinary tract infection. All these complications were managed properly and none of them underwent reoperation.
 Conclusion: Modified pedicle subtraction osteotomy is a safe and effective technique for the treatment of old fracture with kyphosis.

PURPOSE: We aimed to analyze the characteristics of urinary retention (UR) in female inpatients managed with medical treatments. MATERIALS AND METHODS: We retrospectively analyzed the medical records of female inpatients referred to the department of urology for UR at our institution from January 2009, to December 2014. UR was defined as a difficulty in self-voiding despite a sufficient urine volume or >300-mL postvoid residual. The data included patients' age, body mass index (BMI), ambulatory status, medical and surgical history, classes of taking drugs, and urinary tract infection. RESULTS: A total of 182 women were included as retention group, mean age of 72.64±12.94 years and BMI of 22.94±3.10 kg/m2. In the chi-square analysis, cardiovascular disorders (p=0.000), diabetes mellitus (p=0.008), metastatic malignancy (p=0.008), chronic renal disorders (p=0.028) were found significantly. In the multiple logistic regression analysis, cardiovascular disorders (p=0.002; odds ratio [OR], 0.491), metastatic malignancy (p=0.013; OR, 2.616) were found to increase the risk of UR. The most common surgical history was anti-incontinence surgery (7.2%). In term of medication use, the most prescribed agents were nonsteroidal anti-inflammatory drugs (NSAIDs) (53.8%). The patients taking multiple drugs with antimuscarinic effects except of NSAIDs, narcotics and diuretics were 48 (26.4%). Urinary tract infection was identified in 43 patients (23.6%). CONCLUSIONS: UR in females managed with medical treatments could be occurred occasionally. We think that thorough attentions are needed for UR to patients with cardiovascular disorders including diabetes mellitus, metastatic malignancy, chronic renal disorders urinary tract infection, and more careful interests when managing with drugs with antimuscarinic effects.

PURPOSE: To evaluate the medium-term efficacy and safety of transobturator four-arm polypropylene mesh in the treatment of high-stage anterior vaginal wall prolapse and concomitant stress urinary incontinence (SUI). MATERIALS AND METHODS: Between September 2010 and August 2013, a prospective single-center trial was performed to evaluate women with stage> or =3 anterior vaginal wall prolapse with or without SUI who presented to Labbafinejad Hospital, Teheran, Iran, and underwent anterior vaginal wall repair with polypropylene mesh. Pre- and postoperative evaluation included history; physical examination using the Pelvic Organ Prolapse Quantification system and cough stress test, both before and after reduction of prolapsed structures; Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ); urinalysis and culture; and a postvoid residual assessment. Complications were reported at a mean of 2 years of follow-up. RESULTS: A total of 71 patients underwent cystocele repair with the transobturator four-arm polypropylene mesh. Seven of the patients were lost to follow-up. There were no perioperative complications. The anatomical success rate was 87.5%. The subjective success rate was 92.1%. The PFDI and PFIQ were significantly improved after surgery (p<0.001). Among those with the simultaneous complaint of SUI, 82% were cured without any additional procedure. Three patients (4.6%) experienced vaginal mesh extrusion. Two patients (3.1%) reported worsening of dyspareunia after surgery. CONCLUSIONS: The four arms polypropylene mesh is an effective device for simultaneous correction of anterior vaginal wall prolapse and SUI with a low complication rate at a medium-term follow-up. The majority of the subgroup with concomitant SUI were cured without a second simultaneous procedure.

PURPOSE: Complications after prostate biopsy have increased and various causes have been reported. Growing evidence of increasing quinolone resistance is of particular concern. In the current retrospective study, we evaluated the incidence of infectious complications after prostate biopsy and identified the risk factors. MATERIALS AND METHODS: The study population included 1,195 patients who underwent a prostate biopsy between January 2007 and December 2012 at Chung-Ang University Hospital. Cases of febrile UTI that occurred within 7 days were investigated. Clinical information included age, prostate-specific antigen, prostate volume, hypertension, diabetes, body mass index, and biopsy done in the quinolone-resistance era. Patients received quinolone (250 mg intravenously) before and after the procedure, and quinolone (250 mg) was orally administered twice daily for 3 days. We used univariate and multivariate analysis to investigate the predictive factors for febrile UTI. RESULTS: Febrile UTI developed in 39 cases (3.1%). Core numbers increased from 2007 (8 cores) to 2012 (12 cores) and quinolone-resistant bacteria began to appear in 2010 (quinolone-resistance era). In the univariate analysis, core number> or =12 (p=0.024), body mass index (BMI)>25 kg/m2 (p=0.004), and biopsy done in the quinolone-resistance era (p=0.014) were significant factors. However, in the multivariate analysis adjusted for core number, the results were not significant, with the exception of BMI>25 kg/m2 (p=0.011) and biopsy during the quinolone-resistance era (p=0.035), which were significantly associated with febrile UTI. CONCLUSIONS: Quinolone resistance is the main cause of postbiopsy infections in our center. We suggest that further evaluation is required to validate similar trends. Novel strategies to find alternative prophylactic agents are also necessary.
