Preoperative and Intraoperative Urine Cultures and Its Association With Postoperative Infection After Ureteroneocystostomy. Urology 2024; 183:176-184. [PMID: 37774848 DOI: 10.1016/j.urology.2023.09.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 09/05/2023] [Accepted: 09/12/2023] [Indexed: 10/01/2023]
Abstract
OBJECTIVE To unveil this association, we hypothesize that preoperative and intraoperative urinary tract infection (UTI) will be correlated with postoperative UTI and sepsis occurrence. PATIENTS AND METHODS The 2020 National Surgical Quality Improvement Program Pediatric (NSQIP-P) data was analyzed for patients undergoing ureteroneocystostomy (UNC) for vesicoureteral reflux (VUR). Patients that underwent UNC for treatment of VUR with urine culture obtained within 2weeks preoperatively or on the day of surgery were identified. The patients were divided into 3 groups: no bacterial growth, bacterial growth with UTI, and bacterial growth polymicrobial growth. Patient demographics and preoperative variables were evaluated. RESULTS The postoperative urinary tract infection rate of the three groups were 2.0%, 9.2%, and 9.9% for group A, B, C, respectively (P < .001). Postoperative sepsis was noted to be 0.5%, 1.3%, and 3.6% for group A, B, C (P < .01). Additionally, there was a difference between mean operative time (P < .001), mean length of stay (P = .03), and mean days from operation to discharge (P < .01). On adjusted analysis, both groups B and C had higher rates of UTI compared to group A. Group C was also seen to have greater rates of sepsis on adjusted analysis. CONCLUSION The association found between preoperative UTI with less than 2 species of microorganisms (group B) and postoperative UTI indicates that UTI treatment and antibiotic prophylaxis should be considered when undergoing UNC for VUR. The results of this study may lead to more careful consideration of the use of preoperative and intraoperative urine culture as well as treatment of UTI in pediatric patients with VUR undergoing UNC.

[PMID: 34364812 DOI: 10.1016/j.jpurol.2021.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 07/06/2021] [Accepted: 07/09/2021] [Indexed: 11/15/2022]
Abstract
BACKGROUND Ureteral remodeling (tapering or tailoring) is often performed alongside ureteroneocystostomy (ureteric reimplantation) procedures despite limited evidence on its role in promoting reflux resolution. OBJECTIVES To investigate the efficacy of ureteroneocystostomy in the absence of adjuvant ureteral remodeling for promoting reflux resolution in grade III-V vesicoureteral reflux. STUDY DESIGN A retrospective analysis identified pediatric patients who underwent open or robotic assisted ureteroneocystostomy (OUN and RAUN, respectively) without ureteral remodeling (tailoring or tapering) at a single tertiary care center. The primary endpoint of reflux resolution was defined as no reflux on latest follow up postoperative voiding cystourethrogram (VCUG). Ureteral dilation was analyzed using the ureteral diameter ratio (UDR), which normalized for image characteristics. Inclusion criteria was as follows: grade III-V reflux, accessible postoperative VCUG scan, RAUN after June 2013 following technique optimization, and no other structural urologic abnormality or associated neurogenic bladder. RESULTS A total of 68 ureters were analyzed (Grade III = 28, Grade IV = 27, Grade V = 13, OUN = 23, RAUN = 45). Complete reflux resolution was achieved postoperatively in 96% (27/28) of grade III, 100% (27/27) of grade IV and 100% (13/13) grade V cases, for a combined resolution rate of 99%. In the one failed case, the preoperative UDR was in the second quartile and postoperatively, reflux diminished from grade III to grade I. Notably, no cases with UDRs in the largest quartile required tapering/tailoring for complete reflux resolution. DISCUSSION Ureteral tapering and tailoring were unnecessary to achieve reflux resolution in grade III-V VUR by both OUN and RAUN. Additionally, the unsuccessful case was classified as grade III with a UDR value in the second quartile, suggesting that high grade reflux (IV-V) can be repaired without tapering with equal success rates to that of grade III VUR repair, which is classically not tapered. Tapering was unnecessary for complete reflux resolution in the cases with the largest ureteral diameter ratios (UDR). These findings are limited by the single center retrospective nature of the study. CONCLUSIONS This study demonstrates that vesicoureteral reimplantation for resolution of grade III-V reflux is successful in the absence of ureteral remodeling techniques.

Abstract
Introduction Vesicoureteral Reflux (VUR) is characterized by a retrograde flow of urine from the bladder into the ureters and kidneys. It is one of the most common urinary tract anomalies and the major cause of urinary tract infection (UTI) in the first years of life. If not properly diagnosed and treated can lead to recurrent UTI, renal scar and, in severe cases, to end stage renal disease. Despite recent advances in scientific and technological knowledge, evaluation and treatment of VUR is still controversial and there is still considerable heterogeneity in evaluation methods and therapeutic approaches. The aim of the present consensus is to give a practical orientation on how to evaluate and treat VUR. Methods The board of Pediatric Urology of the Brazilian Society of Urology joined a group of experts and reviewed all important issues on Vesicoureteral Reflux evaluation and treatment and elaborated a draft of the document. On November 2017 the panel met to review, discuss and write a consensus document. Results and Discussion Vesicoureteral Reflux is a common and challenging problem in children. Children presenting with Vesicoureteral Reflux require careful evaluation and treatment to avoid future urinary tract infections and kidney scars. The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies.

Proprietary non-animal stabilized hyaluronic acid/dextranomer gel (NASHA/Dx) for endoscopic treatment of grade IV vesicoureteral reflux: Long-term observational study. J Pediatr Urol 2020; 16:328.e1-328.e9.

Abstract
BACKGROUND Since 1993, children aged >1 year with persistent grade III-V vesicoureteral reflux (VUR) and febrile urinary tract infections (UTIs) attending Uppsala University Hospital have undergone endoscopic injection with proprietary non-animal stabilized hyaluronic acid/dextranomer gel (NASHA/Dx; Deflux®). OBJECTIVE Investigate long-term incidence of UTI, bladder dysfunction, ureteral reimplantation and overall clinical findings following endoscopic injection of NASHA/Dx. STUDY DESIGN Children with grade IV VUR diagnosed by voiding cystourethrogram (VCUG) and dilating VUR persisting for >1 year were included in this study. 15-25 years after endoscopic treatment, patients' hospital charts were studied. Information on bladder function and UTIs was obtained via questionnaire, 8-18 years after endoscopic treatment. RESULTS 185 patients (69 boys, 116 girls) were included in the study; 237 grade IV VUR ureters were treated. All study patients were diagnosed with VUR after a febrile UTI (i.e. pyelonephritis). According to the last voiding cystourethrogram, 69% of ureters showed a positive response (VUR grade 0-I), 7% had VUR grade II and 23% had VUR grade ≥ III. 46 patients (25%) required ureteral reimplantation during follow-up. Among patients treated during the second 5-year period compared with the first (1998-2003 versus 1993-1998), there was a significant decrease in the rate of ureteral reimplantation (31% vs 16%; p = 0.0365). This difference may be attributable to developments over time in the injection technique. UTIs occurred in 30 patients (21% of the evaluable population): 28 females and 2 males. Febrile UTIs were reported in 14 patients (10%), all females. Forty-nine patients (34%) had bladder problems (e.g. underactivity, overactivity, incontinence). Five patients underwent ureteral reimplantation 'late', 6-10 years after the last endoscopic injection. In one male patient, calcification around the NASHA/Dx implantation site was observed during routine examination 2 years after endoscopic treatment; no intervention was required. No safety issues were observed in the remaining 97% of the study population. CONCLUSIONS This study represents the longest published follow-up of Grade IV VUR patients undergoing endoscopic treatment. Three-quarters of patients did not need ureteral reimplantation. Optimal injection technique and higher injection volume were associated with a reduced ureteral reimplantation rate. Treatment with NASHA/Dx was durable and well tolerated: long-term risks of UTI, bladder dysfunction and recurrent VUR were low.

Abstract
Urinary tract infection is a bacterial infection that commonly occurs in children. Vesicoureteral reflux is a major underlying precursor condition of urinary tract infection, and an important disorder in the field of pediatric urology. Vesicoureteral reflux is sometimes diagnosed postnatally in infants with fetal hydronephrosis diagnosed antenatally. Opinions vary regarding the diagnosis and treatment of vesicoureteral reflux, and diagnostic procedures remain debatable. In terms of medical interventions, options include either follow‐up observation in the hope of possible spontaneous resolution of vesicoureteral reflux with growth/development or provision of continuous antibiotic prophylaxis based on patient characteristics (age, presence/absence of febrile urinary tract infection, lower urinary tract dysfunction and constipation). Furthermore, there are various surgical procedures with different indications and rationales. These guidelines, formulated and issued by the Japanese Society of Pediatric Urology to assist medical management of pediatric vesicoureteral reflux, cover the following: epidemiology, clinical practice algorithm for vesicoureteral reflux, syndromes (dysuria with vesicoureteral reflux, and bladder and rectal dysfunction with vesicoureteral reflux), diagnosis, treatment (medical and surgical), secondary vesicoureteral reflux, long‐term prognosis and reflux nephropathy. They also provide the definition of bladder and bowel dysfunction, previously unavailable despite their close association with vesicoureteral reflux, and show the usefulness of diagnostic tests, continuous antibiotic prophylaxis and surgical intervention using site markings.

Abstract
OBJECTIVE To determine the long-term safety and efficacy of ureteric reimplantation with psoas bladder hitch (PBH) in patients aged <12 months with unilateral obstructive megaureter (OM). PATIENTS AND METHODS We retrospectively compared a group of patients aged <12 months (study group) with an group of patients aged ≥12 months (comparison group), who underwent PBH for OM between September 2007 and April 2017, in terms of preoperative patient characteristics, intra- and peri-operative results, and postoperative results. RESULTS The study group comprised seven infants, five boys and two girls. The median (range) age at the time of PBH was 3 (2-8) months; OM was detected by ultrasonography during the fetal period. The left side was affected in four infants and the right side in three. Four infants had primary OM (POM). In all three infants who had ectopic OM in the complete double renal pelvis and ureter, the OM involved the ureter from the upper half of the kidney. The median (range) follow-up period after PBH was 45 (33-129) months. Comparison of the two groups showed no significant difference in terms of surgical time (P = 0.948) and length of hospital stay (P = 0.125). In both groups, hydroureteronephrosis improved postoperatively in all patients. There was no significant difference between the two groups in terms of postoperative complications, such as vesico-ureteric reflux, febrile urinary tract infection and deterioration of ipsilateral renal function. Notably, no patient underwent reoperation in either group. CONCLUSION Psoas bladder hitch for unilateral OM including POM appears to be safe and effective in the long term for patients aged <12 months and for those aged ≥12 months. Although not routinely recommended, PBH appears to be a viable option for selected infants with POM.

Abstract
Purpose: To report our initial experience with a modified ureteral orthotopic reimplantation technique under pneumovesicum and compare the outcomes vs. those obtained with the Cohen technique under pneumovesicum for the correction of primary obstructive megaureter (POM) or vesicoureteral reflux(VUR) in pediatric patients. Methods: A total of 46 patients (38 POM and 8 VUR; mean age: 16.24 months) treated with modified ureteral orthotopic reimplantation (OR) and 43 patients (34 POM and 9 VUR; mean age: 22.98 months) treated with Cohen reimplantation (CR) under pneumovesicum were included. We compared the results perioperatively and during follow-up. Results: The mean operative time was significantly shorter in the OR group (OR: 86.86 and 108.18 vs. CR: 95.14 and 124.29 min for unilateral and bilateral cases, respectively). The mean postoperative hospital stay (OR: 5.02 vs. CR: 5.07 days), blood loss (OR: 3.67 vs. CR: 3.84 ml), and follow-up time (OR: 23.17 vs. CR: 23.37 months) did not exhibit significant differences between the two groups. One patient converted to open surgery in the CR group, whereas there was no conversion in the OR group. Postoperative febrile urinary tract infection occurred in two cases in each group. Both infections were controlled using antibiotics. All patients in both groups showed improved hydroureteronephrosis, and all patients with VUR showed reflux resolution post-surgery. Conclusions: Our modified ureteral orthotopic reimplantation technique under pneumovesicum can be safely and effectively performed, achieving a high success rate that is equivalent to that obtained through the Cohen technique under pneumovesicum. Moreover, it involves a simpler procedure and shorter operation time.

Abstract
Deep infiltrating endometriosis (DIE) is the most severe form of endometriosis. It causes chronic pelvic pain, severe dysmenorrhea, deep dyspareunia, dyschezia, and dysuria, markedly impairing the quality of life of women of reproductive age. A number of randomized controlled trials on surgical and medical treatments to reduce the pain associated with endometriosis have been reported, but few have focused on this in DIE. DIE causes not only pain but also functional invasion to the urinary organs and bowel, such as hydronephrosis and bowel stenosis. In addition to DIE resection, surgical treatment involves adhesion separation as well as resection and reconstruction of the urinary organs and bowel; high-level skills are required. The severity of DIE should be evaluated preoperatively as accurately as possible. Using ENZIAN in conjunction with the AFS (The revised American Fertility Society classification of endometriosis) classification makes a more detailed assessment of DIE possible. The operative procedures used for laparoscopic resection of urinary DIE and reconstruction of the urinary organs are chosen based on the type of lesion (intrinsic/extrinsic) and length of stenosis. In addition to ureteroneocystostomy, the psoas bladder hitch and Boari bladder flap procedures are applied when necessary to extend the urinary tract. Bowel resection for bowel endometriosis is classified into classic segmental resection and conservative approaches (shaving/discoid). When these procedures are employed, it is advisable to work in consultation with urologists and gastroenterologists and to inform the patients of the associated risks and outcomes. Furthermore, postoperative medication is essential because it is difficult to conduct repeated surgeries.

Abstract
Introduction: The aim is to compare the outcome of open versus laparoscopic Lich-Gregoir technique in patients with vesicoureteral reflux. We report a retrospective multicenter comparative study between open and laparoscopic extra-vesical ureteral reimplantation (EVUR) following Lich-Gregoir (LG) technique for the correction of Vesico-Ureteral Reflux (VUR). Materials and Methods: Between January 2007 and December 2015, 96 patients with VUR (69 females and 27 males) and deterioration of the renal function, underwent EVUR following LG technique. Fifty patients (16 males and 34 females) were operated by open surgery (group A). The mean age was 4.22 years-old, (14-147 months). Laparoscopic approach (group B) was performed in 46 patients (11 males and 35 females). The mean age was 4.19 years-old (15-110 months). We compared the results in relation to degree of VUR, operative time, hospital stay, post-operative pain medications, recovery time, complications, successful rate, recurrence, and follow-up. Statistical analysis was done used Chi square test for categorical variables and the Student t-test for continuous variables. P < 0.05 was considered significant. Results: In both groups no correlation was identified between age or weight and operative time, length of stay or total analgesia used. The mean operative time for group A was 63.2 and 125.4 min for unilateral and bilateral VUR, respectively, and for the group B was 127.90 and 184.5 min, respectively. There was no conversion in the laparoscopic group. Perioperative mucosal perforation of the bladder occurred in 6 patients of group A and 4 patients of group B and was immediately repaired. One patient had to be reoperated for leakage in group B. The mean duration of Morphine, IV and PO analgesia was shorter in group B. The mean hospital stay was 5.46 days for group A and 1.54 days for Group B. The success rate was 98% in group A and 97, 8% in group B. The mean follow-up was 3.67 years for the open and 1.54 years for the laparoscopic group. Transitory voiding dysfunction occurred in bilateral EVUR in one case in each group. Conclusion: Laparoscopic or Open approach for the correction of VUR following Lich-Gregoir technique is effective in unilateral and bilateral VUR with similar results. Laparoscopic approach reduces significantly (p < 0.05 in each item) post-operative pain medication, hospital stay, and allows for a faster return to normal activity.

Abstract
INTRODUCTION/BACKGROUND The choice between endoscopic injection (EI) and ureteroneocystotomy (UNC) for surgical correction of vesicoureteral reflux (VUR) is controversial. OBJECTIVE To compare postoperative outcomes of EI vs UNC. STUDY DESIGN This study reviewed linked inpatient (SID), ambulatory surgery (SASD), and emergency department (SEDD) data from five states in the United States (2007-10) to identify pediatric patients with primary VUR undergoing EI or UNC as an initial surgical intervention. Unplanned readmissions, additional procedures, and emergency room (ER) visits were extracted. Statistical analysis was performed using multivariate logistic regression using generalized estimating equation (GEE) to adjust for hospital-level clustering. RESULTS The study identified 2556 UNC and 1997 EI procedures. Compared with patients undergoing EI, those who underwent UNC were more likely to be younger (4.6 vs 6.0 years, P < 0.001), male (30 vs 20%, P < 0.001), and publicly insured (34 vs 29%, P < 0.001). As shown in Summary Figure, compared with EI, UNC patients had lower rates of additional anti-reflux procedures within 12 months (25 (1.0) vs 121 (6.1%), P < 0.001), but a higher rate of 30-day and 90-day readmissions and ER visits. On multivariate analysis, patients treated by UNC remained at higher odds of being readmitted (OR = 4.45; 2.69 in 30 days; 90 days, P < 0.001) and to have postoperative ER visits (OR = 3.33; 2.26 in 30 days; 90 days, P < 0.001); however, EI had significantly higher odds of repeat anti-reflux procedures in the subsequent year (OR = 7.12, P < 0.001). DISCUSSIONS Endoscopic injection constituted nearly half of initial anti-reflux procedures in children. However, patients treated with UNC had significantly lower odds of requiring re-treatment in the first year relative to those treated with EI. By contrast, patients treated with UNC had more than twice the odds of being readmitted or visiting an ER postoperatively. Although the available data were amongst the largest and most well validated, the major limitation was the retrospective nature of the administrative database. The practice setting may not be generalizable to states not included in the analysis. CONCLUSIONS Postoperative readmissions and ER visits were uncommon after any surgical intervention for VUR, but were more common among children undergoing UNC. The EI patients had a more than seven-fold increased risk of surgical re-treatment within 1 year.

Abstract
BACKGROUND Vesicoureteral reflux is a risk factor for progressive renal damage. In addition to long-term antibiotic prophylaxis and open surgical re-implantation, endoscopic sub-mucosal intra-ureteral injection of implant material is a therapeutic alternative that gained a world-wide preference. OBJECTIVE The aim of this study was to determine the effectiveness and safety of the implant material, dextranomer/hyaluronic acid, in a cohort of Saudi children with vesicoureteral reflux. METHODS In this case-series study, 61 patients with vesicoureteral reflux, who were 7 months to 10 years old (mean age 2.6 years), underwent sub-mucosal intra-ureteral injection of dextranomer/hyaluronic acid at our institutions in the period from October 2003 to October 2013. The operative protocol was the same in all institutions. Dextranomer/hyaluronic acid was injected submucosally within the intramural ureter (modified STING). Renal ultrasonography was performed to detect the presence of hydronephrosis. At 6 weeks' fluoroscopic voiding cystourethrograms were used to evaluate the success of the technique. Data were analysed by SPSS version 19 using Pearson Chi square, Fisher's Exact and Cramér's V test. RESULTS Reflux was corrected in 44 patients out of 61 (72.13%) and in 60 (75.00%) out of 80 ureteric units. Statistically, there was no significant difference (p>0.05) in success rate of the technique according to gender, age group and unilateral vs. bilateral cases. The success rate was significantly (p=0.025) higher in the lower grades (I-III) (87.50%) compared to grade IV (73.53%) and grade V (50.00%). No complications related to the technique were reported. The technique had failed in 17 patients (27.87%) or 20 ureters (25.00%). These cases underwent open surgery. CONCLUSION Sub-mucosal intra-ureteral implantation with dextranomer/hyaluronic acid by the modified STING technique is a simple, safe and effective outpatient procedure for vesicoureteral reflux.

Abstract
PURPOSE The advent of online task distribution has opened a new avenue for efficiently gathering community perspectives needed for utility estimation. Methodological consensus for estimating pediatric utilities is lacking, with disagreement over whom to sample, what perspective to use (patient vs parent) and whether instrument induced anchoring bias is significant. We evaluated what methodological factors potentially impact utility estimates for vesicoureteral reflux. MATERIALS AND METHODS Cross-sectional surveys using a time trade-off instrument were conducted via the Amazon Mechanical Turk® (https://www.mturk.com) online interface. Respondents were randomized to answer questions from child, parent or dyad perspectives on the utility of a vesicoureteral reflux health state and 1 of 3 "warm-up" scenarios (paralysis, common cold, none) before a vesicoureteral reflux scenario. Utility estimates and potential predictors were fitted to a generalized linear model to determine what factors most impacted utilities. RESULTS A total of 1,627 responses were obtained. Mean respondent age was 34.9 years. Of the respondents 48% were female, 38% were married and 44% had children. Utility values were uninfluenced by child/personal vesicoureteral reflux/urinary tract infection history, income or race. Utilities were affected by perspective and were higher in the child group (34% lower in parent vs child, p <0.001, and 13% lower in dyad vs child, p <0.001). Vesicoureteral reflux utility was not significantly affected by the presence or type of time trade-off warm-up scenario (p = 0.17). CONCLUSIONS Time trade-off perspective affects utilities when estimated via an online interface. However, utilities are unaffected by the presence, type or absence of warm-up scenarios. These findings could have significant methodological implications for future utility elicitations regarding other pediatric conditions.

Abstract
Introduction: Ureteral endometriosis is a rare disease affecting women of childbearing age which presents with nonspecific symptoms and it may result in severe morbidity. The aim of this study was to review evidence about incidence, pathogenesis, clinical presentation, diagnosis, and management of ureteral endometriosis. Materials and Methods: PubMed Central database was searched to identify studies reporting cases of ureteral endometriosis. “Ureter” or “Ureteral” and “Endometriosis” were used as key words. Database was searched for articles published since 1996, in English without restrictions regarding the study design. Results: From 420 studies obtained through database search, 104 articles were finally included in this review, including a total of 1384 patients with ureteral endometriosis. Data regarding age, location, pathological findings, and interventions were extracted. Mean patients' age was 38.6 years, whereas the therapeutic arsenal included hormonal, endoscopic, and/or surgical treatment. Conclusions: Ureteral endometriosis represents a diagnostic and therapeutic challenge for the clinicians and high clinical suspicion is needed to identify it.

Abstract
BACKGROUND Open trigonoplasty antireflux operation has been associated with promising results. However, its success in controlling reflux has not been evaluated in the long term. METHODS All patients who underwent trigonoplasty for vesicoureteral reflux by one surgeon from 2004 to 2014 were included. Preoperative evaluations included direct radionuclide cystography (DRNC) or voiding cystourethrography, urine analysis and culture and abdominal sonography. Urodynamic study and cystoscopy was performed in selected patients. Trigonoplasty was done by a modified Gil-Verent method. The latest available patients' DRNCs were used to judge for reflux relapse. RESULTS Ninety-one patients, 142 refluxing units; median (range) age, 10.5 (1-45) years; M/F, (11/80) were followed for 18 to 135 months. Reflux resolution rate was 73.6% for patients and 75.4% for refluxing units. Relapse was associated with reflux grade (67% in grade V), ureteral orifice appearance (40% in golf hole/stadium), and patients with a history of pyelonephritis. Multivariable model based on the above variables had less than 10% sensitivity in predicting relapse. CONCLUSIONS Trigonoplasty success rate can decrease with long-term follow-up.

Abstract
INTRODUCTION Although cross-trigonal ureteral reimplantation (Cohen) is a commonly used technique in children, it represents a non-physiological transfer of the ureteral orifices and may prove challenging with regard to endoscopic ureteral operations in later life. In 1964, Mathisen described an alternative method of ureteral reimplantation with lateralization of the neohiatus, creating an orthotopic course of the submucosal ureter. We have evaluated success and complication rates of both techniques that were applied sequentially at our departments. METHODS Forty-eight consecutive patients (83 ureters, 24 males/24 females) following Mathisen reimplantation were compared with 53 consecutive patients (98 ureters, 30 males/23 females) following Cohen reimplantation. Inclusion criteria were primary vesicoureteral reflux (VUR) and no previous intervention. Reflux grades (Mathisen 58 ureters/69.9% VUR ≥ III; Cohen 66 ureters/66.7% VUR ≥ III) and the occurence of other complicating factors (ureteroceles, megaureters, posterior urethral valves) in both groups were comparable. RESULTS After Cohen's reimplantation there were no immediate complications requiring intervention; during follow-up (mean 28.2 months) three patients (5.6%) suffered febrile urinary tract infections (UTIs), of which one (1.8%) was diagnosed with a persisting VUR. Persistent hydronephroses (≥II SFU) were recorded in six patients (13.2%). After reimplantation using Mathisen's technique, two patients (4.1%) suffered significant intravesical bleeding; during follow-up (mean 23.06 months) four patients (8.3%) suffered febrile UTIs, and seven patients (14.5%) were diagnosed with persisting VUR after a mean follow-up of 10.8 months. The patients with persistent VUR had more commonly high-grade (IV and V) VUR initially, compared to the whole group. Two patients (4.1%) had persistent hydronephroses (≥II SFU). Mathisen's technique for ureteral reimplantation yielded a significantly (p = 0.0256 patients, p = 0.006 ureterorenal units) lower success rate (85.5% patients, 89.2% ureterorenal units) in comparison with Cohen's technique (98.2% patients, 99% ureterorenal units). Although there was no intervention for obstruction, persistent hydronephrosis was more common in the Cohen group (13.2% vs. 4.1%, n.s.). CONCLUSIONS Despite the advantages of an orthotopic ureteral orifice close to the bladder neck, as achieved by Mathisen's reimplantation, cross-trigonal ureteral reimplantation proved more reliable for VUR correction. As regards optimizing the results, patient selection for either technique could prove essential. Nevertheless, as regards the difficulties with ectopic ureteral orifices in the Cohen technique in the long-term follow-up, the concept of anatomic, orthotopic ureteral reimplantation should be pursued and the technique should be further refined.

Abstract
Vesicoureteral reflux (VUR) represents one of the most significant risk factors for acute pyelonephritis in children. Endoscopic treatment of VUR dates back to 1981 when Matouschek first described injection of the ureteral orifice in an attempt to correct VUR. In addition, also Politano and colleagues and McDonald described successful correction of reflux using endoscopic techniques. After these reports subureteral Teflon injection (STING) came to be appreciated as a viable new way to less invasively correct one of the most common pediatric urologic problems. The technique is technically easy to perform and is usually performed as an outpatient procedure. It is performed in general anesthesia in children and may require repeat injections, particularly in patients with high-grade reflux. As for endoscopic technique, a main problem existed. The success in children with high grade reflux was less than reported for open or laparoscopic reimplant techniques. However, in the past 10 years, newer products have become available that are changing the indications for endoscopic correction. In these review, we analyzed the papers published in the literature on this topic to give to the readers an updated overview about the results of endoscopic treatment of VUR after 30-years of his first description.

Abstract
BACKGROUND Laparoscopic ureteral reimplantation is a feasible method for treating ureteral pathology with good preliminary results in the literature. In this study, we review medium term results for laparoscopic ureteral reimplantation and discuss current developments of this procedure. METHODS Medline and Embase databases were searched using relevant key terms to identify reports of paediatric laparoscopic extravesical ureteral reimplantation (LEVUR). Literature reviews, case reports, series of <3 children and adult studies (age >20 years) were excluded. RESULTS Five studies were assessed, overall, 69 LEVUR were performed in children. Despite different surgical technique, in all case the technique was respected. Patient demographics, preoperative symptoms, radiological imaging, complications, and postoperative outcomes were analyzed. Median success rate was 96%. Complications were reported in five cases. CONCLUSIONS This study is limited by the data given in the individual series: varied criteria used for patient selection and outcome as well as inconsistent pre- and post-operative imaging data precluded a meta-analysis. But it demonstrates that the laparoscopic ureteral reimplantation is an effective procedure with good medium-term results. We believe that in well selected patients this procedure will become an established treatment option.

Abstract
INTRODUCTION Open ureteroneocystostomy (UNC) is the gold standard for surgical correction of vesicoureteral reflux (VUR). Beyond single-center reports, there are few published data on outcomes of minimally-invasive (MIS) UNC. Our objective was to compare postoperative outcomes of open and MIS UNC using national, population-level data. METHOD We reviewed the 1998-2012 Nationwide Inpatient Sample to identify pediatric (≤18 years) VUR patients who underwent either open or MIS UNC. Demographics, National Surgical Quality Improvement Program (NSQIP) complications, length of stay (LOS), and cost data were extracted. Statistical analysis was performed using weighted, hierarchical multivariate logistic regression (complications) and negative binomial regression (LOS, cost). RESULTS We identified 780 MIS and 75,976 open UNC admissions. Compared with patients undergoing open UNC, patients who underwent MIS UNC were likely to be older (6.2 versus 4.8 years, p < 0.001), publically insured (43 versus 26%, p < 0.001), and treated in recent years (90 versus 46% after 2005, p < 0.001). MIS admissions were associated with a significantly shorter length of stay (1.0 versus 1.8 days, p < 0.001) and higher cost ($9230 versus $6,304, p = 0.002). After adjusting for patient-level confounders (age, gender, insurance, treatment year, and comorbidity), and hospital-level factors (region, bedsize, and teaching status), MIS UNC was associated with a significantly higher rate of postoperative urinary complications such as UTIs, urinary retention, and renal injury (OR 3.1, p = 0.02), shorter LOS (RR 0.8, p = 0.02), and higher cost (RR 1.4, p = 0.008). DISCUSSION Strengths of this study are its large cohort size, long time horizon, national estimation, and cost data. Most prior studies are case-series limited to the size of the institutional cohort. Our analysis of 76,756 operative encounters revealed that open UNC continues to be performed at far greater frequency than MIS UNC, outpacing the latter modality by nearly 100:1. Children treated with MIS UNC had three times greater odds of developing postoperative urinary complications, and MIS UNC patients incurred average costs per admission that were nearly 1.5 times higher than those of children who underwent open UNC. These children were also likely to be older, publically insured, and treated in more recent years. On the other hand, patients treated with MIS UNC required substantially shorter postoperative hospitalization, with an average LOS roughly half that of open UNC cases. Limitations include the retrospective nature of the administrative database, lack of detailed patient-level data, and no available long-term postoperative outcomes. Compared with open surgery, MIS UNC was associated with shorter LOS but higher costs and possibly higher urinary complication rates.

Abstract
AIM Our retrospective study compared the results of three surgical procedures for correction of pediatric vesicoureteral reflux (VUR): open Cohen, laparoscopic Lich-Gregoir reimplantation (LEVUR), and endoscopic subureteric injection (STING) procedure. METHODS We analyzed 90 patients (50 girls, 40 boys, average age 4.86 years) operated in two centers of pediatric surgery for VUR. Exclusion criteria were Grade 1 VUR, Grade 5 VUR with megaureters requiring ureteral tapering, secondary VUR, and patients already operated for VUR. Thirty patients underwent Cohen, 30 LEVUR, and 30 STING procedure. Follow-up included renal ultrasonography and voiding cystourethrography 6 months postoperatively. The statistical analysis was performed using χ(2) Pearson and Fisher tests. RESULTS Operative time was shorter using STING either for unilateral or bilateral correction (P = .001). Hospitalization was statistically shorter using STING and LEVUR compared to Cohen (P = .001). The pain scores were worse after Cohen (P = .001). Analgesic requirements were higher after Cohen (P = .001). Reflux persistence was higher after STING (10 cases versus 5 Cohen and 4 LEVUR). Cohen presented more complications compared to LEVUR and STING (P = .001). Intraoperative costs were higher for STING procedure (P = .001), while hospitalization costs were significantly higher for Cohen procedure (P = .001). CONCLUSIONS In children affected by VUR, open Cohen and LEVUR reported a higher success rate than STING procedure. However, Cohen procedure had a very long and painful hospital stay, more complications, more analgesic requirements compared to STING and LEVUR. Comparing the three techniques, it seems that LEVUR presents a high success rate similar to the Cohen procedure, but in addition, it presents the same advantages of STING procedure with no postoperative pain and a lower postoperative morbidity.

Abstract
INTRODUCTION Laparoscopy in pediatric patients offers more benefits than was earlier presumed and these widely reported benefits significantly outweigh any concerns regarding the technical difficulties. Laparoscopic correction of vesicoureteral reflux aims to duplicate the excellent results of open surgery while at the same time reducing perioperative morbidity and analgesic requirements, improving cosmesis and shortening hospital stay. OBJECTIVE To share our experience of laparoscopic extravesical detrusorraphy, highlight our technical modification of intraoperative minimal "atraumatic" ureteric handling of the ureter, which we hypothesize may decrease ureteral complications, and report our results. STUDY DESIGN This was a retrospective chart review of 76 toilet-trained children (98 refluxing units), in the age group of 3-16 years, with Grade I-IV reflux, who underwent laparoscopic detrusorraphy from June 2006 to January 2014. A ureteric catheter is inserted into the refluxing ureter and is tied to the Foleys to drain into a common bag. A three port technique is used. During ureteral dissection, a vascular sling in the form of a Rumel loop is used for atraumatic handling of the ureter. A detrusor tunnel is created with hook electrocautery. A stay suture is later passed through the abdominal wall and slings around the dissected ureter, which helps in holding the ureter approximated against the mucosal trough during detrusorraphy. Detrusor fibers are approximated with 5-0 Vicryl. No drain is placed and the Foley and ureteric catheter(s) are removed after 24 h. Intravenous ketorolac is given every 6 h for the first 24 h. Oral paracetamol is used for analgesia after the first 24 h. Adequate bladder emptying is ensured by assessment of post void residual urine before discharge. Renal USG alone is performed 2 weeks post operatively and repeated after 3 months along with a VCUG (voiding cystourethrography). Success was defined as absence of reflux in the follow-up VCUG done at 3 months. RESULTS Mean operative time was 102 ± 26.5 min for unilateral detrusorraphy and 165 ± 18 min for bilateral extravesical detrusorraphy. The mean duration of hospital stay was 1.5 ± 1.7 days. There was one case of urinary retention that was managed with temporary recatheterization. There were no cases of ureteral ischemia, obstruction, hematuria or bladder spasms. Surgery was successful in 97.9% of the refluxing units (96/98). In two patients with grade IV reflux, there was downgrading to grade II on VCUG done at 3 months' follow-up. The reflux resolved at 8 and 14 months' follow-up, respectively. DISCUSSION Our technique of atraumatic handling of the ureter, initially with the help of a vascular sling and later with the help of a stay suture passed percutaneously through the abdominal wall, resulted in no ureteric injuries. The postoperative morbidity of this procedure is low because the bladder is not opened, the ureter is not transected, no new UVJ is created and there is no need for placement of a drain. The risk of postoperative bowel adhesions is low as the ureter is dissected out through a narrow peritoneal window, which is again extraperitonealized at the end of the procedure (see figure). The postoperative complications of gross hematuria and bladder spasms, which may be especially encountered in patients undergoing laparoscopic Cohen's, were not seen in our case series. CONCLUSION Laparoscopic extravesical detrusorraphy provides a minimally invasive treatment option for treatment of unilateral/bilateral grade I-IV vesicoureteral reflux. The postoperative morbidity is low and the success rate is favorable. Our technical modification of a "vascular sling" around the ureter facilitates atraumatic ureteric handling, which may reduce distal ureteral complications like ureteral ischemia and obstruction.

Abstract
OBJECTIVES To compare the outcomes of the Politano-Leadbetter and Cohen techniques in laparoscopic pneumovesicum approach for ureteral reimplantation. METHODS We retrospectively reviewed the medical records of 24 patients who underwent transvesicoscopic ureteral reimplantation during the period from 2007 to 2014. The patients were treated with either the Cohen or Politano-Leadbetter technique. Operative duration, duration of hospital stay, and success and complication rates were compared. RESULTS Operative duration was 1 h longer for the Politano-Leadbetter technique than for the Cohen technique (P < 0.05). Foley catheters were removed 2-3 days after the procedures. The mean hospital stay was 3.6 days. Reflux completely resolved in 21 patients (35 ureters, 94.6%), but not in two patients (2 ureters). There was no difference in the success rate or durations of catheterization or hospital stay between patients treated with the Politano-Leadbetter technique and those treated with the Cohen technique. CONCLUSIONS The Politano-Leadbetter and Cohen techniques are both reliable for transvesicoscopic ureteral reimplantation. Despite a longer operative time, because of the higher surgical complexity, the Politano-Leadbetter ureteral reimplantation offers important physiological advantages over other techniques.

Abstract
We aimed to study the safety and efficacy of the cystoscopy-assisted nonrefluxing ureteral reimplantation technique using submucosal tunneling during laparoscopic ureteroneocystostomy (UNC) with a psoas hitch in patients with distal ureter stricture after gynecologic surgery. We reviewed six female patients who underwent gynecological surgeries. All patients showed persistent postoperative distal ureter stricture or obstruction. These patients underwent laparoscopic nonrefluxing UNC with a psoas hitch using a submucosal tunneling technique combined with cystoscopy at our institute. They had corrective surgery at an average of 13.3 weeks after ureteral injury. The short-term success was confirmed either by voiding cystourethrography (VCU) or by diuretic isotope renal scan (MAG-3) conducted 3 months after the operation. None of the patients showed evidence of postoperative stricture at the reimplanted site and reflux on either MAG-3 renal scan or VCU. None of the patients showed major or minor complications during follow-up. It is safe and feasible to perform the laparoscopic nonrefluxing UNC with a psoas hitch using a submucosal tunneling technique combined with cystoscopy for ureteral stricture.

Abstract
Urinary tract infections (UTIs) represent an important cause of febrile illness in young children and can lead to renal scarring and kidney failure. However, diagnosis and treatment of recurrent UTI in children is an area of some controversy. Guidelines from the American Academy of Pediatrics, National Institute for Health and Clinical Excellence and European Society of Paediatric Radiology differ from each other in terms of the diagnostic algorithm to be followed. Treatment of vesicoureteral reflux and antibiotic prophylaxis for prevention of recurrent UTI are also areas of considerable debate. In this review, we collate and appraise recently published literature in order to formulate evidence-based guidance for the diagnosis and treatment of recurrent UTI in children.

Abstract
Approaches to the management of children with urinary tract infection (UTI), vesicoureteral reflux (VUR), and renal scars have been challenged and have become controversial over the past decade. It is difficult to determine when, how, and which patients will benefit from the diagnosis and management of this condition. Therefore, the issues of diagnostic imaging, observation, follow-up, and intervention tend to be decided more on a case-by-case basis, rather than by using an algorithm. Over the past few years, there have been advances in the identification of risk factors that predispose patients with UTI to present with VUR, to develop recurrent UTIs and renal scars, to have deteriorating renal function, to show VUR improvement and/or spontaneous resolution, and to be candidates for and benefit from early surgical intervention.

Abstract
BACKGROUND Traditional pediatric ureteral reimplantation involved blindly passing a clamp behind the bladder to guide the ureter into a new hiatal opening, potentially resulting in an intraperitoneal ureter. CASE A 44-year-old woman with previous ureteral reimplantation underwent gynecologic laparoscopy. Two fibrous bands attached a segment of small bowel to the abdominal wall. One band was transected and ligated. Postoperative suspicion that the bands represented ureter prompted computed tomography imaging, showing high-grade ureteral obstruction. Retrograde pyelogram revealed urinary extravasation and no continuity with the ureter. Reoperation with ureteroneocystotomy confirmed the bands were ureter coursing through bowel, consistent with injury during ureteral reimplantation. CONCLUSION Review of previous surgeries, a high index of suspicion, and prompt urologic consultation are recommended to identify and repair ureter injuries in abnormal anatomy cases.

Abstract
INTRODUCTION Vesico-ureteral reflux (VUR) is a common congenital anomaly of the urinary tract in the pediatric population, existing controversy regarding its management. Patients selected for treatment options are offered, from endoscopic injection of substances sub-ureteral to ureteral reimplantation surgery. OBJECTIVE To evaluate the use of the laparoscopic surgical technique for the treatment of vesico-ureteral reflux, with an analysis of the procedure, results and complications. MATERIAL AND METHODS We evaluated a series of 50 ureteral units in 42 patients, who undergoing laparoscopic transperitoneal ureteral reimplant, using the classic technique of Lich-Gregoir detrusorrafia. RESULTS The mean operative time was 74 min. There were no intraoperative nor immediate postoperative. At longer follow-up VUR was cured in all cases. CONCLUSIONS Laparoscopic surgery is an effective alternative in the surgical treatment of vesico-ureteral reflux, with results comparable to open surgery techniques and over sub-ureteral injection techniques.

Abstract
Endoscopic treatment is a minimally invasive treatment for managing patients with vesicoureteral reflux (VUR). Although several bulking agents have been used for endoscopic treatment, dextranomer/hyaluronic acid is the only bulking agent currently approved by the U.S. Food and Drug Administration for treating VUR. Endoscopic treatment of VUR has gained great popularity owing to several obvious benefits, including short operative time, short hospital stay, minimal invasiveness, high efficacy, low complication rate, and reduced cost. Initially, the success rates of endoscopic treatment have been lower than that of open antireflux surgery. However, because injection techniques have been developed, a recent study showed higher success rates of endoscopic treatment than open surgery in the treatment of patients with intermediate- and high-grade VUR. Despite the controversy surrounding its effectiveness, endoscopic treatment is considered a valuable treatment option and viable alternative to long-term antibiotic prophylaxis.

Abstract
BACKGROUND/OBJECTIVE As renal transplantation may increase survival rates and improve quality of life for children with end-stage renal disease, we investigated the long-term outcomes and prognostic factors of pediatric renal transplantation. METHODS A retrospective study was conducted to review 25 pediatric renal transplantations, either from live or deceased donors, in our hospital from 1995 to 2008. The cumulative graft survival rate was calculated using the Kaplan-Meier method. Log rank tests were employed to identify categorical prognostic factors for graft survival of the pediatric renal transplantations, and Cox regression analysis for numeric factors. RESULTS The mean age of our study subjects was 11.63±3.76 years, and the mean follow-up period was 49.24±33.72 months. The 12-month and 36-month graft survival rates were 92% and 82.14%, respectively. The rejection-free survival rates were 88% and 72.88% in the first and third years, respectively. All of the patients were alive during the follow-up period. Acute rejection (p=0.0175) and male sex (p=0.0384) were found to be significant factors for graft survival. CONCLUSION For pediatric patients, we found that renal transplantation is now a safe and effective surgical procedure for children with end-stage renal disease. Acute rejection and male gender were identified as prognostic factors for poor graft survival.

Abstract
Hypertension affects about 65 million individuals in the United States. In adult patients, primary aldosteronism and renovascular causes are described as most prevalent. Vesicoureteral reflux as a cause of hypertension, while commonly described in pediatric populations, is less prevalent in the adult population especially in the absence of proteinuria. We present the case of a 31-year-old female presenting with early onset hypertension. Workup for renovascular hypertension was unrevealing. She was found to have right-sided vesicoureteral reflux with a unilateral scarred kidney. Patient underwent a nephrectomy with marked improvement in blood pressure control.

Abstract
Vesicoureteral reflux (VUR) affects around 1% of all children. It carries an increased risk of febrile urinary-tract infections (UTIs) and is associated with impaired renal function. Antibiotic prophylaxis is an established approach to managing the condition, but it does not protect against UTI and encourages bacterial resistance. Ureteral re-implantation (open surgery) is a relatively traumatic procedure typically requiring hospitalization, and there is a risk of significant post-treatment complications. Endoscopic treatment with NASHA/Dx gel (Deflux®) is minimally invasive, well tolerated and provides cure rates approaching those of open surgery: 80-90% in several studies. It has also been shown to be effective in a variety of 'complicated' cases. Thus, endoscopic treatment is generally preferable to open surgery and long-term antibiotic prophylaxis. Non-treatment of VUR is being discussed as an alternative option, although this mainly appears suitable for children with low-grade reflux and normal kidneys. A new approach to managing VUR may be considered, with treatment decisions based not only on the grade of reflux but also on factors such as age, sex, renal scarring and bladder dysfunction. Open surgery would be reserved only for use in the 10-15% of children not responding to endoscopic treatment and those with severe ureteral anomalies.

Abstract
PURPOSE We investigated associated urodynamic abnormalities in toilet trained children with vesicoureteral reflux. MATERIALS AND METHODS A total of 298 toilet trained children with primary vesicoureteral reflux underwent urodynamic evaluation. Urodynamic parameters were reviewed and correlated with age, gender, presence of lower urinary tract symptoms and reflux severity. RESULTS Symptomatic lower urinary tract symptoms were present in 111 children (37.2%, group 1). Children with lower urinary tract symptoms had significantly decreased severity of vesicoureteral reflux compared to children without these symptoms (187 patients, group 2). The majority of the patients had normal early bladder compliance regardless of presence of lower urinary tract symptoms or reflux grade. On the other hand, decreased late bladder compliance was more common in group 1 vs group 2. Ratio of cystometric bladder capacity to expected bladder capacity was higher in group 2. Detrusor overactivity was observed in 28.5% of the children, and the incidence was significantly higher in group 1 vs group 2, and in mild vs moderate or severe reflux. Dysfunctional voiding from bladder sphincter dyscoordination was seen in 32% of children 2.5 to 4 years old with vesicoureteral reflux and lower urinary tract symptoms, compared to 8% in children 5 to 16 years old. CONCLUSIONS The presence of lower urinary tract symptoms in children with vesicoureteral reflux correlated well with some urodynamic findings suggestive of overactive bladder and negatively correlated with reflux severity. In contrast, dysfunctional voiding was more common in younger children with reflux and lower urinary tract symptoms. These findings suggest that treatment of voiding dysfunction should be directed toward the specific type of abnormality in children with vesicoureteral reflux.

Abstract
OBJECTIVES Endoscopic injection of non-animal-stabilized hyaluronic acid/dextranomer gel is an increasingly recognized treatment option for vesicoureteral reflux. The procedure is minor compared with open surgery and, when successful, avoids the need for long-term antibiotic prophylaxis. We present data from 3 years of using non-animal-stabilized hyaluronic acid/dextranomer gel to treat children with vesicoureteral reflux. METHODS Pediatric patients aged 16 years with uncomplicated primary vesicoureteral reflux were recruited for endoscopic treatment with non-animal-stabilized hyaluronic acid/dextranomer gel. A follow-up voiding cystourethrogram was scheduled at 2 weeks after treatment, and vesicoureteral reflux resolution was defined as grade 0. Repeat non-animal-stabilized hyaluronic acid/dextranomer gel treatment was offered to patients with persistent vesicoureteral reflux. RESULTS Of 178 patients treated, 12 were lost to follow-up or yet to undergo post-treatment voiding cystourethrogram. The 166 remaining patients (efficacy population) had a mean age of 4.21 years (range: 0-16), and the median reflux grade was 3 (range: 1-5). Vesicoureteral reflux was resolved in 81.9% of patients and 86.4% of ureters after initial endoscopic treatment with non-animal-stabilized hyaluronic acid/dextranomer gel. The overall reflux resolution rate for patients increased to 89.6% after a second treatment in 19 patients, and 90.2% after a third treatment in 1 patient. No adverse events were reported. Five patients underwent open ureteral reimplantation after failed endoscopic injections. CONCLUSIONS Endoscopic treatment with non-animal-stabilized hyaluronic acid/dextranomer gel is effective in a high proportion of children with vesicoureteral reflux and, in our opinion, should be considered as a first-line treatment option.

Abstract
OBJECTIVE Laparoscopic ureteral reimplantation is a feasible method for treating ureteral pathology with good preliminary results in the literature. In this study, we review our medium-term results for laparoscopic ureteral reimplantation and discuss current developments of this procedure. MATERIALS AND METHODS Twenty-four laparoscopic ureteral reimplantations were performed between August 2003 and December 2008 for ureteral strictures or ureteral injuries. The mean age was 53.5 years (8 men, 16 women). Patient demographics, preoperative symptoms, radiological imaging, complications, and postoperative outcomes were analyzed. Ten patients underwent vesicopsoas-hitch, nine patients had a vesicopsoas-hitch combined with Boari-flap, and five had Lich-Gregoir extravesical ureteral reimplantations. Success was defined as relief of obstruction on postoperative imaging studies, as well as symptomatic relief. RESULTS Laparoscopic ureteral reimplantations were successfully performed in all patients. The mean operative time was 215 min (131-351). Mean estimated blood loss was 283 ml (50-550). One patient had an intraoperative bowel injury which was managed laparoscopically during the same procedure. There were two postoperative complications; two prolonged ileus and one deep venous thrombosis (DVT). Mean hospital stay was 8.7 days. Average time to return to normal activity was 2.6 weeks. Postoperative radiological imaging studies showed good drainage, without hydronephrosis, in 23 patients (success rate 95.8 %) at a median follow up interval of 35 months. CONCLUSIONS Laparoscopic ureteral reimplantation is an effective procedure with good medium-term results. We believe that this procedure will become an established treatment option.

Abstract
Endoscopic subureteric injection of tissue-augmenting substances has become an alternative to long-term antibiotic prophylaxis and open surgery, in the treatment of children with vesicoureteric reflux (VUR). Successful elimination of reflux in about 80% of patients after a single injection (and in 90% after a repeat) has been achieved using non-degradable substances. young girl with grade III VUR and breakthrough infections would definitely need to undergo antireflux procedure. Endoscopic treatment would be an ideal procedure as it is a one-day surgery, with over 80% success rate, low morbidity and no long-term complications. Moreover, this form of surgery is appealing to, as well as the choice of the majority of parents.

Abstract
BACKGROUND To validate its safety and efficacy, we evaluated our preliminary results of the three-port minilaparoscopic nerve-sparing extravesical ureteral reimplantation for patients with vesicoureteral reflux (VUR). METHODS Between July 2005 and February 2007, 9 consecutive patients (4 girls and 5 boys) with a mean age of 3.4 years (range, 7 months to 5 years) underwent a minilaparoscopic nerve sparing extravesical ureteral reimplantation for VUR. A 30-degree 3-mm telescope and two 3-mm trocars were used for the reimplantation. Minimal handling and dissection of the ureter and ureterovescial junction was adhered to spare the nerves. RESULTS A total of 14 ureters were reimplanted (4 unilateral and 5 bilateral). Mean follow-up period was 8.7 months. The mean operative time was 170 minutes in unilateral reimplantations and 218 minutes in the bilateral one. There was no intraoperative complication. All patients resumed oral intake in the first postoperative morning. The Foley catheters were removed within 24-36 hours after surgery. None of them had urinary retention after catheter removal. Voiding cystourethrography was done 3-4 months after surgery. A complete resolution of reflux was identified in 11 of 14 units, a downgrading of reflux in 2 of 14 units, and ureterovesical junction stenosis in 1 of 14. Open reimplantation was done for the ureter with postoperative ureterovesical junction stenosis. CONCLUSIONS The three-port minilaparoscopic nerve-sparing extravesical ureteral reimplantation was a safe, effective techinique for the treatment of VUR.

Abstract
Long term controlled studies in children with vesicoureteral reflux (VUR) largely conducted in developed societies, challenge the validity of established management principles.The backflow of urine into the upper tracts is not a disease by itself, but part of a clinical spectrum which is heterogeneous and has low risk and high risk categories. Management, medical, endoscopic or surgical have to take into consideration the risk to the child not only from the reflux but also from renal dysplasia and voiding dysfunction which are important risk factors for end stage renal disease (ESRD) and perpetuation of VUR respectively. Social factors, parental choices and access to medical treatment are also important in choosing therapy.

Abstract
Significant controversy exists regarding vesicoureteral reflux (VUR) management, due to lack of sufficient prospective studies. The rationale for surgical management is that VUR can cause recurrent episodes of pyelonephritis and long-term renal damage. Several surgical techniques have been introduced during the past decades. Open anti-reflux operations have high success rate, exceeding 95%, and long durability. The goal of this article is to review the Gil-Vernet trigonoplasty technique, which is a simple and highly successful technique but has not gained the attention it deserves. The mainstay of this technique is approximation of medial aspects of ureteral orifices to midline by one mattress suture. A unique advantage of Gil-Vernet trigonoplasty is its bilateral nature, which results in prevention from contralateral new reflux. Regarding not altering the normal course of the ureter in Gil-Vernet procedure, later catheterization of and retrograde access to the ureter can be performed normally. There is no report of ureterovesical junction obstruction following Gil-Vernet procedure. Gil-Vernet trigonoplasty can be performed without inserting a bladder catheter and drain on an outpatient setting. Several exclusive advantages of Gil-Vernet trigonoplasty make it necessary to reconsider the technique role in VUR management.

Abstract
In addition to conventional open surgery and endoscopic techniques, laparoscopic correction of vesicoureteric reflux, sometimes even robot-assisted, is becoming an alternative surgical treatment modality for this condition in a number of centres around the world. At least for a subgroup of patients laparoscopists are trying to develop new techniques in an effort to combine the best of both worlds: the minimal invasiveness of the STING and the same lasting effectiveness as in open surgery. The efficacy and potential advantages or disadvantages of these techniques are still under investigation. The different laparoscopic techniques and available data are presented.

Abstract
OBJECTIVE Vesicoureteral reflux (VUR) can be treated with open surgery, antibiotic therapy or endoscopic injection. A goal in children is to reduce the incidence of febrile urinary tract infections (UTIs). The present long-term observational study investigated outcomes and experiences of endoscopic treatment with stabilized non-animal hyaluronic acid/dextranomer, NASHA/Dx. PATIENTS AND METHODS Children treated with NASHA/Dx between 1993 and 1998 were sent a questionnaire by mail in 2005. Patients included in the study (n=231) had VUR grade III-V before treatment and grade 0-II afterwards. Patients completed 21 questions, with parental assistance if required. The questionnaire assessed clinical outcome, and the attitudes of both patients and their parents to their experiences of treatment with NASHA/Dx gel. Patients reporting UTI after treatment were contacted and their records analyzed. RESULTS Questionnaires were completed by 179 eligible patients. Most (72%) received a single injection of NASHA/Dx gel, and all experienced febrile UTI before treatment. After treatment, 45 patients (25%) experienced UTI; 25 of these reported fever. Patient records and telephone interviews revealed no evidence of febrile UTI in 19 cases; febrile UTI was confirmed in six cases, an incidence of 3.4%. When asked about the worst aspect of VUR treatment, 9% indicated treatment with NASHA/Dx compared to 19% for medication and 72% for voiding cystourethrogram (VCUG); parent-rated responses were 19%, 24% and 57%, respectively. CONCLUSIONS Endoscopic treatment with NASHA/Dx gel was associated with a low number of febrile UTIs following treatment, viewed positively and considered less bothersome than medication or VCUG. These findings support this treatment as a primary intervention for VUR.

Abstract
INTRODUCTION In bilateral VUR, Cohen cross-trigonal ureteric reimplantation is a popular but also controversial surgical approach. We present our own experience in a retrospective analysis. PATIENTS AND METHODS Between 1990 and 2005, 41 children (26 girls, 15 boys) with bilateral reflux [92 renal units (RU)] underwent ureteric reimplantation. The mean age was 4.5 (0.3-12) years. Eight patients had ureteral duplication (six unilateral, two bilateral); 12 of 41 patients had no intraoperative ureteral stenting. Seven patients had prior surgery for VUR. A successful result was defined as absence of VUR, significant UVJ obstruction, or voiding dysfunction throughout the follow-up. RESULTS The mean follow-up was 7.8 (0.5-15) years. Eight patients (19.5%) had 13 complications. One patient had an intraoperative small bowel lesion (2%). Six patients (14.6%) had UTI. Four patients (9.8%) showed transient UVJ obstruction. Three required a temporary percutaneous nephrostomy. Two of these patients had no intraoperative ureteral stenting. Recurrence of VUR was found in 2 patients (4.8%) and 2/92 RU (2.2%), respectively. Complications were more frequent in high-grade VUR, ureter duplex, or unstented ureteral reimplantation. Prior surgery for VUR did not influence the postoperative outcome. Postoperative voiding disorders were not observed. CONCLUSIONS Two unilateral recurrences of VUR were observed, requiring a reoperation in one patient. A reoperation for UVJ obstruction was not necessary. Related to 92 RU the surgical success rate was 97.8%. Intraoperative ureteral stenting has to be considered with respect to the current discussion of shortening inpatient procedures. In our experience, the perioperative risk was elevated in patients with high-grade VUR or ureteral duplication.

Abstract
PURPOSE We describe a novel technique of extracorporeal tailoring for megaureter to perform laparoscopic extravesical transperitoneal ureteral reimplantation. We present our initial results with this procedure. MATERIALS AND METHODS Three cases of megaureter were operated on laparoscopically. The 3-port technique was used (all 5 mm in 2 cases, and 2, 5 mm and 1, 10 mm in 1). The colon was reflected medially to expose the retroperitoneal course of the ureter. The ureter was gently dissected circumferentially down to the bladder. It was ligated close to the bladder and divided proximal to it. The free ureteral end was delivered out through the ipsilateral 5 mm port. The lower end was tailored over an 8Fr feeding tube. A 6Fr Double-J stent was placed. Later the whole assembly was carefully replaced in the abdomen. A Lich-Gregoir type extravesical reimplantation was done. RESULTS Mean operating time was 220 minutes (range 210 to 240), which included 15 to 20 minutes to exteriorize the ureter, complete extracorporeal tailoring and replace the stented ureter in the abdomen. Mean blood loss was 40 ml. Cystourethrogram at 3 months did not demonstrate any reflux. Renal scan showed preserved renal function in all 3 cases, with prompt drainage in 2 and delayed drainage in 1. At a mean followup of 12 months all 3 patients were asymptomatic. CONCLUSIONS Extracorporeal tailoring for obstructing megaureter is an easy and safe procedure that makes laparoscopic ureteral reimplantation simpler and quicker to perform.

The procedure is minor compared with open surgery and, when successful, avoids the need for long-term antibiotic prophylaxis. We present data from our first 18 months using nonanimal stabilized hyaluronic acid/dextranomer gel to treat children with vesicoureteral reflux. PATIENTS AND METHODS Pediatric patients aged < or = 15 years with uncomplicated primary vesicoureteral reflux were recruited for endoscopic treatment with nonanimal stabilized hyaluronic acid/dextranomer gel. A follow-up voiding cystourethrogram was scheduled at > or = 2 weeks after treatment, and vesicoureteral reflux resolution was defined as grade 0. Repeat nonanimal stabilized hyaluronic acid/dextranomer gel treatment was offered to patients with persistent vesicoureteral reflux. RESULTS Of 120 patients treated, 6 were lost to follow-up, and 7 were yet to undergo posttreatment voiding cystourethrogram. The 107 remaining patients (efficacy population) had a mean age of 4.1 years (range: 0.5-15.0), and the median reflux grade was 2 (range: 1-5). The mean time to follow-up voiding cystourethrogram was 9.7 weeks (range: 2-26). Vesicoureteral reflux was resolved in 82.2% of patients and 86.9% of ureters after initial endoscopic treatment with nonanimal stabilized hyaluronic acid/dextranomer gel. The overall reflux resolution rate for patients increased to 90.7% after a second treatment in 14 patients. Two patients reported postoperative flank pain, although this was mild and transient in nature. No other adverse events were reported. No patients underwent open surgery for vesicoureteral reflux. CONCLUSIONS Endoscopic treatment with nonanimal stabilized hyaluronic acid/dextranomer gel is effective in a high proportion of children with vesicoureteral reflux and, in our opinion, may be considered as a first-line treatment option.
