Abstract
PURPOSE This study aims to compare the outcomes of extravesical (EVUR) and intravesical (IVUR) ureteric reimplantation for primary vesicoureteral reflux (VUR) via systematic review and meta-analysis. METHODS Literature review from Medline, Embase, and Cochrane since inception to March 2022 was performed. Meta-analysis was conducted on eligible randomized controlled trials (RCT) and observational cohort studies (OCS) comparing outcomes between EVUR and IVUR. RESULTS Twelve studies were included, comprising 577 patients (778 ureters) operated by EVUR and 395 patients (635 ureters) by IVUR. Pre-operative VUR grade, postoperative VUR persistence and hydronephrosis was not statistically significant. EVUR had shorter operative time [mean differences (MD) -22.91 min; 95% confidence interval (CI), -44.53 to -1.30, P = 0.04] and hospital stay (MD -2.09 days; 95% CI, -2.82 to -1.36, P < 0.00001) compared to IVUR. Bilateral EVUR had higher risk of postoperative acute urinary retention (ARU) (8.1%) compared to bilateral IVUR (1.7%) (OR = 4.40; 95% CI, 1.33-14.58, P = 0.02). No patient undergoing unilateral EVUR or IVUR experienced ARU. CONCLUSION Both EVUR and IVUR are equally effective in correcting primary VUR. Operative time and hospital stay are shorter after EVUR compared to IVUR. However, bilateral EVUR is associated with higher risk of postoperative ARU.

J Pediatr Urol 2020; 16:449-455. [PMID: 32423705 DOI: 10.1016/j.jpurol.2020.04.024] [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: 02/16/2020] [Revised: 04/18/2020] [Accepted: 04/21/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Anti-reflux surgery success has been well-documented in the literature. Little data exists about the characterization of the child's symptoms regarding pain, bladder spasms, and hematuria following these procedures. These symptoms may affect the choice of surgery for families and providers. OBJECTIVE To characterize parent's perception of recovery from surgery and preparedness for recovery from surgery. We hypothesized that parents of children undergoing open intravesical reimplantation (Open) would report a higher incidence of bladder spasms and hematuria compared to children undergoing robotic extravesical reimplantation (RALR) or endoscopic treatment (DxHA). STUDY DESIGN A 20-question survey was developed to assess perception of recovery preparedness, pain, and symptoms. Parents completed the survey at a follow-up visit occurring 3-6 weeks post-discharge. Chi-square and t-test or their non-parametric equivalents were used for between-group comparisons. RESULTS Participating were three institutions and eleven surgeons. Eighty-four parents completed the survey a median of 33 days (IQR 27-40) post-surgery. More parents reported bladder spasms and hematuria in the Open group vs RALR and DxHA. Although there was no difference in maximum bladder spasm pain, duration of pain medication for spasms was longer with Open vs RALR. Most parents (87%) reported they were prepared for their child's symptoms after surgery. Approximately one-quarter of parents whose child underwent Open (33%) or RALR (36%) reported the bladder spasms were more painful than expected, and almost half of parents whose child underwent Open (49%) reported hematuria was worse than expected. DISCUSSION We found that Open had significantly worse parental reports of bladder spasms, pain medication usage, and severity of hematuria than RALR and DxHA. Although most parents said they were prepared for their child's recovery, many reported the symptoms were worse than expected. These contradictions may reflect a need for improved physician to parent communication when discussing anti-reflux surgery.

Open versus robot-assisted laparoscopic ureteral reimplantation: Hospital charges analysis and outcomes at a single institution. J Pediatr Surg 2020:S0022-3468(19)30901-7.

Abstract
PURPOSE Robot-assisted laparoscopic extravesical ureteral reimplantation has previously been described as a viable minimally invasive option to open surgery. However, concerns for robotic surgery have been raised owing to assumed higher costs and heterogeneous clinical outcomes. We hypothesized that similar hospital charges and clinical outcomes occur when comparing open and robotic cases in matched cohorts. MATERIALS AND METHODS Open and robotic reimplantation cases from 2013 to 2015 for primary vesicoureteral reflux were matched by age using 1:1 nearest neighbor matching. The matched cohorts were analyzed and compared for their direct itemized hospital charges per surgical case, complications, and clinical outcomes. RESULTS There were 38 patients in each group after age-matching the 135 patients. Operating room charges were higher for the robotic group compared to the open group (p=0.002), whereas pharmacy and laboratory costs were lower for the robotic group. However, there were no significant differences in total overall charges between the open and robotic groups with cystoscopy or without cystoscopy (p=0.345, p=0.533), since the median hospital stay length was shorter for the robotic group (p<0.001). Clinical success rates were identical for the two groups (open 94.8% vs robotic 94.8%). There were also no significant differences in number of complications between the two cohorts. CONCLUSIONS This is the first age-matched study comparing hospital charges and clinical outcomes of pediatric open and robotic reimplantation. While operating room charges were higher for the robotic cohort, lower hospitalization charges led to comparable overall hospital charges, as well as equivalent clinical outcomes for both cohorts. LEVEL OF STUDY Level III (Retrospective comparative study) TYPE OF STUDY: Retrospective Study.

Abstract
BACKGROUND Duplication of ureters is a common anatomic abnormality and occurs in 0.7% to 1% of the general population. In this article we focus on the safety of using of kidneys with complete ureteral duplication, provided no hydronephrosis or ureterocele was present in the donor. METHODS From 1998 to March 2018 there were 1965 kidneys transplanted at our institution, including 27 kidneys with duplicated ureter, which corresponds to incidence of 1.4%. Patients' medical records, surgery protocols, and Poltransplant registries were searched for urinary complications. RESULTS In the double ureter group, urologic complications occurred in 4 patients (15.4%). Similarly, severe urinary complications developed in 4 patients from the control group (17.4%). CONCLUSIONS Transplantation of kidneys with duplicated ureters appears to be a safe and feasible procedure.

Abstract
INTRODUCTION Historically, patients with unilateral high-grade vesicoureteral reflux (VUR) and contralateral low-grade or resolved VUR have been treated with bilateral intravesical ureteral reimplantation, which requires postoperative admission. If the high-grade VUR side is treated alone, then the contralateral side is at risk of developing recurrent or worsening VUR. Bilateral subureteric injection of dextronomer/hyaluronic acid (DHA) is another option that can be performed as an outpatient therapy, but a single injection is less effective for high-grade VUR. OBJECTIVE The safety and efficacy of an outpatient combination of open extravesical ureteral reimplantation (EVUR) and contralateral DHA injection were investigated. STUDY DESIGN A retrospective review of children who had concomitant EVUR and subureteric injection of DHA between January 2005 and December 2015 was performed. Exclusion criteria were diagnosis other than VUR, repeat procedures, and patients with no follow-up. Patient characteristics, postsurgical complications, and follow-up imaging were evaluated. Febrile urinary tract infection (fUTI) was defined as ≥50,000 Colony Forming Units (CFU) of an organism from clean-catch or catheterized urine and temperature ≥ 101.5 F. Clinical success is defined as no fUTI for 1 year after the initial operation. Univariate analyses were used to identify risk factors for treatment failure. RESULTS A total of 117 patients met inclusion criteria. Mean age at surgery was 6.0 years, and 85% were female. The mean pre-operative grade of VUR was 3.3 on the EVUR side and 0.6 on the contralateral side (42% resolved before treatment). Median follow-up was 12.2 months (interquartile range, 3.1-25.4). Sixteen patients (14%) had documented fUTI within 1 year, with a clinical success rate of 86%. Of these, five had a postoperative imaging showing resolution of VUR, increasing overall success to 91%. Postoperative fUTI was more common in patients with pre-operative bowel and bladder dysfunction (BBD) (P = 0.003), but this was not associated with a higher reoperation rate (P = 0.168). There were 11 total complications, with three grade 3 complications. DISCUSSION This study is the first to report safety and outcomes of EVUR and contralateral DHA injection for patients with high-grade VUR with contralateral low-grade or resolved VUR. It was shown that it is an effective and safe treatment that can be performed as an outpatient therapy. Limitations to this study include the retrospective design and the clinical definition of success that is used in a cohort of patients from across the mountain west region without routine postoperative voiding cystourethrogram. CONCLUSION Extravesical ureteral reimplantation and contralateral DHA injection can safely be performed as an outpatient therapy and are effective in the treatment of higher grade VUR with contralateral low-grade or resolved VUR. Treatment failure is more likely in patients with BBD.

Abstract
OBJECTIVE Acquiring surgical skills requires regular practice. Medical evidence supports that these skills can be learned outside the operating room (OR). The aim of the current study was to describe the first laparoscopic simulator for ureteral reimplantation (LAP-SPUR) following Lich- Gregoir technique. MATERIALS AND METHODS LAP-SPUR was manufactured using reusable and disposable materials. The technique can be summarized in the following five steps: (1) a transperitoneal approach; (2) extra-vesical ureteral dissection; (3) detrusor division until exposing the mucosa; (4) reimplanting ureter into the new tunnel; and (5) reapproximation and suturing of the detrusor. LAP-SPUR was evaluated through a survey answered by urologists and surgeons. A 5-point Likert scale was employed for most items and the medians test was chosen to compare the response among physicians according to the number of laparoscopic surgical procedures performed per week (≤2 versus >2) and the experience in ureteral reimplantation of the respondent as a dichotomous variable (0 versus ≥1 repairs). RESULTS Thirty-four surveys were answered. The simulator was reported to: have a very high level of realism by the experts; be a reproducible procedure with similar anatomical structures and working space to pediatric patients by the non-experts; be extremely useful, easy and ergonomic for laparoscopic training outside the OR; be lightweight and portable for straightforward transportation; be inexpensive; and be reusable and have low maintenance requirements. It was found to provide a secure environment for trainees, to enhance cognitive knowledge acquisitions, and to increase technical performance. Only tissue handling was non-significant when groups were compared. CONCLUSION Augmenting surgical dexterity using LAP-SPUR offered great promise because maneuvers could be rehearsed over and over until they were mastered. Of the urologists and surgeons who were evaluated, 100% reported lack of training at their institutions; therefore, all of them would definitely benefit by practicing with LAP-SPUR to enhance technical skill acquirement. Further development and validation are still needed to assess its true benefits.

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 and Objective: Multiple options exist for the surgical management of vesicoureteral reflux (VUR). We report on our 10-year experience using the inguinal approach to extravesical ureteral reimplantation (EVR). Materials and Methods: Patient characteristics of age, gender, and reflux grade were obtained and outcomes of operative time, hospital stay, and radiographic resolution were assessed. Results: 71 girls and 20 boys with a mean age of 74 months (range 14-164) underwent inguinal EVR via a 3.5-cm inguinal mini-incision. Mean follow up was 10.9 months (range 0.4-69.7). Average grade of reflux was 2.80. Average operative time was 91 minutes (range 51-268). The procedure was successful in 87 of 91 patients (95.6%). The 3 cases of reflux that persisted were all grade 1 and managed expectantly. Contralateral reflux developed in 9 cases, all of which resolved after treatment with either Deflux or ureteral reimplant. There were 4 case of urinary retention that resolved after a brief period of CIC or indwelling catheterization. There were no cases of ureteral obstruction. Most patients were discharged on post-operative day 1 (85/91) and no hospitalization extended beyond 3 days. Conclusions: The inguinal approach to extravesical ureteral reimplantation should be considered as a potentially minimally invasive alternative to endoscopic and robotic treatment of VUR with a success rate more comparable to traditional open approaches. We feel it is the method of choice in cases of unilateral VUR requiring surgical correction.

Abstract
INTRODUCTION Primary obstructive ureter (POM) is an upper urinary tract malformation in children. Transvesicoscopic ureteral reimplantation is increasingly being used as the first choice to correct POM, replacing the open extravesical approach. Although several procedures have been reported, there is no universally accepted technique for endoscopic ureteral reimplantation. OBJECTIVE To report on several modifications of the Glenn-Anderson ureteral advancement technique to make it suitable for a laparoscopic pneumovesical approach to treatment of POM. PATIENTS AND METHODS From February 2006 to December 2013, 63 children with POM, 45 male and 18 female (median age 4.2 years; range 2 months-14 years), underwent modified transvesicoscopic ureteral implantation surgery. The technique was modified by repositioning of the hiatus proximally to afford greater "tunnel" length, and use of a trough rather than a tunnel, avoiding the challenges of more adherent mucosa in the trigone. Ureter diameter was followed over a 12-month period post surgery. Voiding cystourethrography (VCUG), intravenous urogram (IVU), or radionuclide imaging were conducted in patients who still had ureteral dilation at 6 months and 12 months after surgery. RESULTS The procedure was successfully performed in 62/63 patients. The mean operating time was 105 min. Twelve months after surgery 90% of ureters were considered cured and 10% were considered improved. In patients who showed improvement ureters, the ureter diameter was significantly reduced from preoperative measurements as early as 1 month post surgery. DISCUSSION The Glenn-Anderson technique advances the ureteral orifice distal to the trigone near the bladder neck and allows relatively easy access to the upper urinary tract. However, the submucosal tunnel produced is relatively short, and the surgery is not recommended for patients with a small trigone or megaureter because of anatomical considerations. This study made two major modifications to the traditional Glenn-Anderson procedure: (1) the bladder wall was incised superiorolaterally to move the hiatus proximally along the course of the ureter and the detrusor muscle was sutured to the seromuscular layer of the ureter, and (2) a mucosal groove rather than tunnel was used for advancement from the ureteral hiatus to the bladder neck. This approach preserves conventional endourologic access to the upper tracts; however, the stabilizing distal stitch does leave the suture line in proximity to the mucosal suture line, a theoretical disadvantage from the standpoint of ureterovesical fistula. CONCLUSIONS These preliminary results indicate that this modified transvesicoscopic ureteral implantation is an effective procedure with minimal morbidity.

Abstract
PURPOSE To describe the surgical procedure of intravesical detrusorrhaphy, a modified technique of ureteral reimplantation, and report our initial experience. METHODS From October 2007 to March 2012, 55 children with vesicoureteral reflux (VUR) and 13 children with obstructive megaureter (OM) underwent intravesical detrusorrhaphy. All surgical procedures were performed via an open intravesical approach. The ureter was mobilized, and the bladder mucosa was separated from the detrusor in a cephalad direction. The separated detrusor was incised vertically and repaired underneath the mobilized ureter to create the submucosal tunnel. The ureteral orifice was anastomosed to its orthotopic position. RESULTS Of 31 patients treated with bilateral intravesical detrusorrhaphy, no patient had postoperative urinary retention. Follow-up voiding cystourethrography was performed in 45 patients with 72 reimplanted ureters. VUR was resolved in 41 patients (91.1%) with 68 ureters (94.4%). Among 13 patients with 14 ureters treated for OM, hydroureteronephorosis improved in 11 patients (84.6%) with 12 ureters (85.7%). CONCLUSIONS Intravesical detrusorrhaphy is modified technique of ureteral reimplantation, which recreates the neo-ureteric orifice in the orthotopic position and does not produce postoperative urinary retention in bilateral cases. Intravesical detrusorrhaphy is safe and effective in treating patients with VUR or OM.

Abstract
Vesicoureteral reflux is a major problem in childhood affecting 1% of all children. There are various surgical methods for vesicoureteral reflux treatment. Current study evaluates effectiveness and success rate of the Lich-gregoir procedure in treatment of the vesicoureteral reflux. In a descriptive-analytical study, 32 children with 47 reflux unit underwent Lich-gregoir anti-reflux procedure in Imam Reza and Amir-al-Momenin Hospitals, Tabriz between March 2008 and August 2011. Surgery outcome and success rate, sonographic findings and complications rate were recorded in follow-up. Patients mean age was 5.85 +/- 3.81 years. 28.1% were male and 71.9% were female. Reflux was unilateral in 53.1% and bilateral in 46.9%. Vesicoureteral reflux grade I to V was in one, 1, 13, 22 and ten patients, respectively. Voiding Cystourethrogram (VCUG) findings were abnormal in all cases before operation. Surgery success rate in first 6 months was 95.7% and was 100% in 8 months after operation. Hydronephrosis disappeared after operation in all cases. Complication occurred in 2 cases (6.25%) with bilateral reflux including urinary intention and lymphocele. Lich-gregoir anti-reflux procedure technique is accompanied with higher success rate, low complication and hydronephrosis improvement and is an appropriate treatment for vesicoureteral reflux in children.

Abstract
The current management of vesicoureteral reflux (VUR) remains controversial. Recent well thought-out randomized studies on VUR in children have led to a debate on diagnostic and therapeutic algorithms. Individual parameters, such as age, gender, clinical course, renal function and scars, dysfunctional elimination syndrome and last but not least the compliance of the parents have gained in importance. Regarding recent data this article gives a summary of diagnostic steps and therapeutic management of VUR.

Abstract
INTRODUCTION Minimally invasive surgery implies a percutaneous or endoscopic approach rather than an incision, regardless of size. However, open approaches to various procedures using a mini-incision should assume the same appellation. We report our experience with extravesical ureteral reimplant (EVR) performed through an inguinal mini-incision. MATERIALS AND METHODS Patient characteristics of age, gender, and reflux grade were obtained, and outcomes of recurrent urinary tract infection, time of surgery, time of hospitalization and radiographic resolution were assessed. The technique involved a 2 cm incision made in the lowest inguinal skin crease, standard hernia exposure, opening of the floor of the inguinal canal to isolate the ureter, detrussorhaphy. RESULTS 30 girls and 15 boys with a mean age of 64 months (range 20-180), and mean followup of 18 months (range 3-36) underwent unilateral inguinal mini-incision EVR. Reflux grades represented were 7, 13, 18, 5, and 2 for Grades I through V respectively. Common sheath reimplantations were performed in twelve duplicated systems, and tapering performed in three patients. The average time of surgery was 75 min. All but 2 patients were discharged within 24 h; postoperative imaging was normal in all cases. Three patients had febrile UTIs following discontinuation of prophylactic antibiotics. CONCLUSION The inguinal approach to EVR is safe, effective, efficient, and well-tolerated. Through several maneuvers learned as the experience with EVR grew, we present a realizable approach to minimally invasive ureteral reimplantation with application in most pediatric urologic practice.

Abstract
Regional analgesia is firmly established in modern pediatric anesthetic practice and its popularity continues to grow. In our department continuous epidural anesthesia (CEA) is a frequently used technique of pain management following major reconstructive procedures of the lower urinary tract. The aim of this study was to investigate the efficacy, safety, and potential benefits of CEA over standard analgesics.We retrospectively reviewed the records of 21 infants who underwent single-stage bladder exstrophy repair in our department. In 15 children an epidural catheter was placed preoperatively for CEA; 6 patients treated without CEA served as controls. Total doses of narcotics and analgesics, length of intensive care unit (ICU) stay and ventilatory assistance, time to first bowel activity, anticholinergic requirements, and CEA-related side effects were documented and compared for both groups.Children given epidural anesthesia required six- to tenfold lower doses of morphine intra- and postoperatively compared to those without CEA; ventilatory support upon completion of surgery was remarkably shorter (59 versus 210 min) in the CEA group as well as ICU stay (1.1 versus 1.8 days). The total consumption of anticholinergics was twice as high as in patients without CEA. There were no relevant CEA-related complications.Being a retrospective audit of practice in our institution with a small number of patients, our results are in line with previously published data on CEA in pediatric patients. CEA has been shown to significantly reduce the need for anesthetics and morphine and allows early extubation with all subsequent advantages for a speedy recovery post surgery. Thus, the technique is to be recommended as a safe and efficacious method for pain management following major reconstructive surgery in pediatric urology. Importantly, this type of anesthesia should be performed only by experienced anesthesiologists in institutions where appropriate equipment, staff, and monitoring are available.

Surgical Reimplantation for the Correction of Vesicoureteral Reflux following Failed Endoscopic Injection. Adv Urol 2011; 2011:352716.

Abstract
Purpose. In recent years, endoscopic injection became the procedure of choice for the correction of vesicoureteral reflux in the majority of the centers. Unfortunately, endoscopic treatment is not always successful and sometimes requires more than one trial to achieve similar results to that of an open reimplantation surgery. Our aim of this study is to evaluate the feasibility and success rate of open ureteral reimplantation following failed endoscopic procedure. Patients and Methods. During 2004-2010, we evaluated 16 patients with persistent vesicoureteral reflux (grades II-IV) following failed endoscopic treatment. All patients underwent open ureteral reimplantation. All patients were followed with an ultrasound 6 weeks following surgery and every 6 months thereafter for an average of 22 months. Voiding cystography was performed at 3 months after surgery. Results. During unilateral open ureteral reimplantation, the implanted deposit from previous procedures was either excised, drained, or incorporated into the neotunnel with the ureter. Vesicoureteral reflux was resolved in all patients with 100% success rate. No new hydronephrosis or signs of obstruction developed in any of the patients. qDMSA renal scan was available in 8 patients showing improvement of function in 5 and stable function in 3, and no new scars were identified. Conclusions. Open ureteral reimplantation is an excellent choice for the correction of failed endoscopic treatment in children with vesicoureteral reflux.

Abstract
The pathophysiology, evaluation and therapy of vesicoureteral reflux (VUR) were newly illuminated over the past years through different clinical studies and basic research. Our understanding of vesicoureteral reflux and the therapeutic spectrum of its treatment should therefore consistently undergo critical revision. The Swedish Reflux Study set up three different therapy options for small children with dilated VUR: antibiotic prophylaxis, endoscopic reflux correction and surveillance were prospectively analysed in a randomized fashion. The results are discussed in this work and completed with a statement about open operative reflux therapy.

Abstract
BACKGROUND Diclofenac is commonly used for acute pain in children, but is not licensed for this indication in all age groups. OBJECTIVES 1) Assess the efficacy of diclofenac for acute pain in children. 2) Assess the safety of diclofenac for short-term use in children. 3) Identify gaps in the evidence to direct future research. SEARCH STRATEGY Seventeen databases indexing clinical trial reports were searched in February 2005 (with an update search as part of this first review in May 2008). A hand search of Paediatric Anaesthesia was undertaken and summaries obtained of adverse reaction reports from the UK Yellow Card Scheme and World Health Organization (WHO) Monitoring Centre. The reference lists of included studies were also searched. SELECTION CRITERIA Any published report, in any language, involving the administration of diclofenac to a patient aged 18 years or younger for acute pain and detailing either monitoring of efficacy or safety. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study quality and extracted the data. Authors were contacted where necessary. Review Manager version 5 was used for analysis. MAIN RESULTS 1) EFFICACY: randomised controlled trials (RCTs) comparing diclofenac with placebo/any other treatment by using pain scores (assessed or reported), or need for rescue analgesia.2) SAFETY: any type of study seeking adverse events (regardless of cause). An adverse event was defined as any reported adverse or untoward happening to a patient being treated with diclofenac for acute pain.Seven publications on diclofenac efficacy and 79 on safety (74 studies plus five case reports) were included in the final analysis. Compared with placebo/no treatment, diclofenac significantly reduced need for post-operative rescue analgesia (relative risk [RR] 0.6; number needed to treat to benefit [NNT] 3.6; 95% confidence interval [CI] 2.5 to 6.3).Compared with any other non-NSAID, patients receiving diclofenac suffered less nausea or vomiting, or both (RR 0.6; NNT 7.7 [5.3 to 14.3]). There appeared to be no increase in bleeding requiring surgical intervention in patients receiving diclofenac in the peri-operative period. Serious diclofenac adverse reactions occurred in fewer than 0.24% of children treated for acute pain. The types of serious adverse reactions were similar to those reported in adults. AUTHORS' CONCLUSIONS Diclofenac is an effective analgesic for perioperative acute pain in children. It causes similar types of serious adverse reactions in children as in adults, but these are rare. More research on optimum dosing and safety in asthmatic children is required.

Abstract
OBJECTIVE The need for surgical correction of vesicoureteral reflux (VUR) is increased in duplicated systems. The aim of this study was to evaluate the outcome of the Lich-Gregoir procedure (LG) with regard to VUR persistence, contralateral de-novo VUR, hydronephrosis, preservation of split renal function, urinary tract infections (UTI) and postoperative side effects. PATIENTS AND METHODS Between 1993 and 2007, 45 children (mean age 3.2 years) underwent a unilateral common sheath LG. A combined number of at least 75 episodes of febrile UTI had occurred in 39 children prior to surgery. VUR grades I to V were present in two, nine, 16, 16 and two children, respectively. Hydronephrosis was present in 18 children. Mean split renal function was 44.03% (range 15-63%). Indications for surgery were febrile breakthrough UTI in 11 children and abscessing pyelonephritis in two. The remainder underwent surgery due to renal scars, reduced split renal function (<45%), VUR persistence and/or parental desire. RESULTS Persistent ipsilateral and de-novo contralateral VUR were detected in three children (ipsilateral in one, contralateral in one, bilateral in one), resulting in a 4.4% rate of persistent ipsilateral VUR. One year post surgery, low-grade hydronephrosis persisted in six patients without impact on split renal function. Mean split renal function remained stable at 44.06% (range 15-68%). During follow up (mean 41 months), six febrile UTIs occurred in five girls (92.4% risk reduction, P<0.00000005). Neither urinary retention nor any other side effect was observed. CONCLUSION Performed unilaterally, common sheath LG is a safe and effective technique to cure VUR, prevent febrile UTI and maintain split renal function in duplicated systems with otherwise uncomplicated anatomy.

Abstract
Taguchi technique of ureteral implantation was used in 22 kidney transplant patients (group T). Group T was compared with 25 patients who were treated using Lich-Gregoir technique (group LG). Immunosuppression, incidence of biopsy evidenced acute cellular rejection (ACR), haematuria rate and ureteral complications (stricture, reflux) were assessed in both groups. The immunosuppression used was based on cyclosporin A (63.6%), tacrolimus (27.3%) and sirolimus (8.1%) in T group. Cyclosporin A(72%), tacrolimus (20%) and sirolimus (8%) were used in LG group. No induction was used. The incidence of ACR was similar in both groups--T resp. LG was 50% resp. 52%. Haematuria after operation was on average 4.0 days in the T group and on average 3.1 in the LG group. Ureteral complications were observed in 18.2% of cases in T group and in 16% of cases in LG group. No reflux was evidenced in any group. Taguchi technique is fast and very easy to do. A slightly higher incidence of ureteralcomplications and a longer period of postoperative haematuria were observed in T group. Taguchi technique is very easily performed with a shorter operating time. We advocate it as a method of ureteral implantation on the thin-wall urinary bladder. The results were very good in these cases.
