Co-existing obstructed and refluxing lower moiety megaureter in a female without incontinence: a perplexing myriad in a duplex system with ectopic lower moiety ureter

Ectopic ureter is a rare congenital anomaly that predominantly affects females and typically manifests as urinary incontinence due to atypical ureteral openings in structures such as the vagina or cervix. This condition is estimated to occur in approximately 1 in 4000-10,000 female births. An exceptional variant, the intrasphincteric ectopic ureter, poses significant diagnostic challenges due to its atypical presentation, as it may cause dynamic obstruction and reflux phenomena without resulting in incontinence. A 28-year-old female presented with severe left flank pain, fever, and chills persisting for 10 days. Her medical history included intermittent dull, aching left flank pain over 7 years, exacerbated during voiding, but no urinary incontinence. Physical examination revealed marked tenderness in the left flank, and laboratory investigations showed elevated leukocyte count and normal serum creatinine levels. Computed tomography urography revealed a left duplex moiety with upper moiety infected hydronephrosis, necessitating percutaneous nephrostomy placement. Subsequent nephrostogram and micturating cystourethrogram identified a grossly dilated and tortuous upper moiety ureter with intrasphincteric ectopic ureteral opening, confirming the diagnosis of obstructed and refluxing megaureter. Following infection resolution, the patient underwent laparoscopic extravesical non-refluxing reimplantation of the upper moiety ectopic ureter with DJ stenting. The postoperative course was uneventful, and the patient reported no flank pain or fever upon stent removal. Periodic evaluations showed no increase in hydronephrosis, indicating a successful intervention. This case underscores the diagnostic complexity of intrasphincteric ectopic ureter, a rare anomaly presenting with obstructed and refluxing megaureter without incontinence. Heightened clinical vigilance and comprehensive radiological evaluation are imperative for timely diagnosis and intervention. Preservation of continence further complicates the clinical picture, necessitating early intervention to prevent renal function deterioration and improve long-term outcomes.

Robot-assisted redo ureteral reimplantation in adults after failed primary surgery: technique and outcomes from two centers.

The aim of this study was to report our technical experience and mid-term outcomes of robot-assisted redo ureteral reimplantation in adults following failed primary ureteral reimplantation. Twelve patients underwent robot-assisted redo ureteral reimplantation from December 2020 to May 2022 at double centers. Surgical procedures included anti-reflux dismembered submucosal tunnel reimplantation, anti-reflux dismembered nipple reimplantation, and anti-reflux non-dismembered submucosal tunnel reimplantation. The perioperative variables were prospectively collected, and the outcomes were assessed. Twelve patients underwent 13 robot-assisted redo ureteral reimplantations. Anastomotic stenosis was the primary cause of redo surgery, accounting for 83.3% of cases. Additionally, 83.3% of patients had received balloon dilation, stent placement, and other urological treatments after primary surgery. All patients successfully underwent robot-assisted redo ureteral reimplantation without conversion to open or laparoscopic surgery. All patients underwent anti-reflux technique, with 9 patients undergoing submucosal tunnel reimplantation (75%) and 3 nipple reimplantation (25%). Psoas hitch was required in eight patients (66.7%). The mean operative time was 129.3±29.0 minutes. The median postoperative hospitalization time was 3.0 (IQR, 3.0, 3.0) days. At a mean follow-up of 15.7±5.9 months, all patients achieved complete success with no severe complication. Two patients (16.7%) still experienced vesicoureteral reflux related symptoms postoperatively, which improved compared to preoperatively. Robotic redo ureteral reimplantation is safe and effective. The success of redo surgery is attributed to preoperative nephrostomy, clearing the fibrous scar surrounding the ureter, appropriate selection of anti-reflux technique, and psoas hitch when needed.

A comparative study on the efficacy of laparoscopic ureteroureterostomy versus single ureteral bladder reimplantation in treating pediatric complete renal duplication.

To explore the therapeutic value of laparoscopic ureteroureterostomy compared to single ureteral bladder reimplantation in the treatment of pediatric complete renal duplication. This retrospective study included 80 pediatric patients with complete renal duplication who underwent surgical treatment at the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022. Patients were divided into two groups based on the surgical approach: the laparoscopic ureteroureterostomy group (LUU group, n = 45) and the single ureteral bladder reimplantation group (UR group, n = 35). The two groups were compared in terms of operative time, intraoperative blood loss, number of stent placements, postoperative length of hospital stay, changes in ante-posterior diameter (APD) of the affected upper kidney pelvis before and after surgery, changes in upper ureteral diameter (UD), changes in upper renal cortex thickness (RCT) and variations in renal function. The LUU group demonstrated significantly shorter operative time (t = 3.480, P = 0.004), less intraoperative blood loss (t = -2.465, P = 0.0196), and reduced postoperative length of stay (t = 2.308, P = 0.027) compared to the UR group. There was no significant difference between the two groups regarding the number of stent placements (x2 = 0.762, P = 0.383). The UR group had four cases of long-term complications (two cases of anastomotic stricture, one case of vesicoureteral reflux, and one case of recurrent urinary tract infection), while the LUU group experienced one case of long-term complication (one case of anastomotic stricture), with no significant difference between groups (x2 = 1.493, P = 0.222). Both groups showed significant improvement in preoperative and postoperative APD, UD, RCT and affected side differential renal function (DRF). However, the differences in improvement values for upper kidney pelvis APD (ΔAPD; t = -0.032, P = 0.962), upper RCT (ΔRCT; t = -0.042, P = 0.957), ureteral diameter (ΔUD; t = 1.832, P = 0.079), and differential renal function (ΔDRF; Z = 1.895, P = 0.073) were not statistically significant. Both LUU and UR procedures are safe and effective in treating pediatric complete renal duplication. Compared to UR, LUU results in shorter operative time, less intraoperative blood loss, and reduced postoperative length of stay, while also causing less damage to the bladder.

Repeated ureterocystoneoimplantation in a 13-year child with recurrent vesicoureteral reflux in both segments of a doubled kidney

Introduction. Doubling of the urinary tract is a common developmental anomaly (0.8–1.0%). With complete doubling, vesicoureteral reflux (VUR) is detected in 66-72%, mainly in the lower segment. The aim of the work is to optimize the surgical treatment of VUR with doubling of the urinary tract by endoluminal plasty of the ureteral mouths and reimplantation of the ureter. Materials and methods. In a 13-year child, a laparoscopic longitudinal intravesical ureterocystoneoimplantation technique was used in conditions of ureteral length deficiency and a proximal intervertebral anastomosis was applied. Results. With the doubling of the urinary tract, a number of patients experience a recurrence of VUR, which determines the need for repeated reconstructive surgery. We present a clinical case of successful surgical treatment of recurrent VUR in both segments of a doubled kidney in a 13-year child. In the treatment, the technique of laparoscopic longitudinal intravesical ureterocystoneoimplantation was successfully applied in conditions of ureteral length deficiency and a proximal intervertebral anastomosis was applied. Conclusion. The performed surgical intervention meets the requirements of efficiency and safety and can be used in conditions of ureteral length deficiency in patients with recurrent VUR after previously performed reconstructive operations.

095. A Rare Case Report: A 10-Years-Old Girl with Ectopic Ureter and Ectopic Hypoplasia Kidney

Background: The urinary tract system develops from an embryological structure in the dorsal part of the embryo, the intermediate mesoderm, which develops between the 4th and 10th week of gestation. During the embryogenesis process, disturbed metanephric mesenchyme can cause congenital abnormalities of the kidneys and urinary tract (CAKUT), one of which is ectopic abnormalities. Ectopic ureter and ectopic kidney had an incidence of 1:2000 and 1:3000 worldwide, respectively. Additionally, this rare case will be even more uncommon with the presence of a hypoplasia kidney. These anomalies contribute to impaired urinary drainage. Case: A 10-year-old girl was referred to the surgical department at Dr. Kariadi Hospital due to continuous urinary incontinence. She can urinate regularly via the urethra, but constantly has vaginal leaks. Previously, she had physiotherapy at the regional hospital but there was no improvement. Contrast-enhanced computed tomography revealed an ectopic kidney image accompanied by right kidney hypoplasia and a cyst on the upper pole of the right kidney measuring ± 0.89 x 0.86 cm. Then, urethrocystoscopy and colposcopy also showed the right ureteral orifice on the superior wall of the vagina, ± 2 cm from the vaginal introitus with the left ureteral orifice in a normal position. The patient underwent ureteral reimplantation, and her symptoms successfully resolved, leading to a favourable prognosis. Conclusion: Complete ectopic ureter and ectopic hypoplasia kidney are rare congenital anomalies that require early recognition and careful management in pediatric patients.

Is There a Consensus on the Management of Primary Obstructive Megaureter?

To analyze the results of a survey regarding the opinion of experts in diagnosis and management of primary obstructive megaureter (POM) and to determine if their current therapeutic strategy matches with the British Association of Pediatric Urologist recommendations, published in 2014. FromFebruary 1 to June 30, 2023, an online-based survey was distributed through the eUROGEN network and some pediatric urology societies. The questionnaire was carried out using google forms and consisted of 14 questions. Additionally, a literature review of the most recent articles was performed. One hundred three medical professionals completed the survey, 98 (96.1%) were pediatric urologists. 67.3% of respondents agreed with starting continuous antibiotic prophylaxis in all patients with POM. The diagnosis of obstruction is mostly made based on a combination of findings which include initial DRF <40%, drop of DRF of >5% on serial scans and worsening of dilation at follow-up ultrasound (63.7%). When specifically asked if initial DRF <40% as a solely finding without symptoms or massive dilatation was considered as an indication for early surgery, only 12 (11.9%) considered it so. Regarding ureteral reimplantation under the age of 1, 46 (45.1%) were confident in this procedure. Among temporizing interventions, high-pressure endoscopic balloon dilatation was the most popular. Current trends in the diagnosis and management of POM may challenge some of the British Association of Pediatric Urologist recommendations, especially in regards initial DRF <40% as a solely indication of surgery and the most popular temporizing procedures. It may be time to elaborate a new updated consensus and decide a common updated approach for all patients with POM.

Isolated laparoscopic extra-vesical ureteric reimplantation (I-LEVUR) for upper moiety ectopic ureter without lower moiety vesicoureteric reflux.

To evaluate the feasibility and outcomes of isolated laparoscopic extra-vesical ureteric reimplantation (I-LEVUR) for upper moiety ectopic ureter in patients with non-refluxing lower moiety ureter and avoid reimplanting normal lower moiety orifice. Between 2013 and 2024, 12 patients (8 females, 4 males) with ectopic ureter associated with a duplex system underwent I-LEVUR. Preoperative assessment included ultrasonography, voiding cystourethrography (VCUG), and magnetic resonance urography (MRU)/retrograde pyelogram (RGP). The procedure involved laparoscopic extravesical approach dissecting only the ectopic ureter in lower most part, preserving vascularity, and performing an isolated reimplantation without manipulating lower moiety ureter. Twelve patients, with a median age of 2.8years, underwent I-LEVUR. The mean operative time was 127.5min. No intraoperative complications occurred. Postoperative follow-up (median: 78.5months) showed no cases of ureteral obstruction or significant complications. Urinary continence improved in all patients. Two patients developed mild vesicoureteral reflux, managed conservatively, and one patient had minor urine leak which resolved spontaneously. I-LEVUR is a viable and effective alternative to traditional en bloc reimplantation for upper moiety ectopic ureter. It preserves the normal ureteric orifice, reduces surgical trauma, and offers excellent outcomes in terms of renal function and urinary continence. Further studies with larger cohorts, control group of common sheath reimplantation, randomization, robust statistical validation and longer follow-up are recommended.

Management of Ureteral Stricture Disease After Radiation Therapy for Pelvic Malignancies: A Retrospective, Multi-Institutional Analysis.

A radiation-induced ureteral stricture (RIUS) is a challenging condition in urologic surgery, and the optimal surgical strategy is still a matter of debate. The aim of this study was to report post-operative outcomes of minimally invasive management of this condition from a multi-institutional cohort. Data of patients with diagnoses of RIUS at five referral robotic centers between January 2017 and December 2022 were retrospectively analyzed. Pre-, intra- and post-operative variables were collected. Recurrence was defined as the presence of flank pain combined with imaging findings for obstruction, and requiring further management. Univariate and multivariate logistic regression models were built to identify predictors of ureteral stricture recurrence. Fifty-three patients with a diagnosis of an RIUS were included. Primary pelvic malignancy was mostly cervical (42%). In 72% of cases (mostly mid-proximal and short strictures) endourological management was attempted, which was deemed successful in 74% of patients at stent removal. The endourology success rate at a median follow-up of 12 months was 59%. Twenty-five patients (47%) were scheduled for robotic surgery. The reconstructive techniques most often performed were end-to-end anastomosis (44%) and ureteral reimplantation (52%). Three low-grade Clavien-Dindo post-operative complications (12%) occurred. Robotic surgery was successful in all cases except one. Considering the entire cohort, eight patients (15%) developed recurrence at a median follow-up of 5 months. All patients with recurrence were managed by permanent drainage. A statistically significant improvement in eGFR with respect to baseline was found at a median follow-up of 12 months (p = 0.007). The univariate logistic regression model identified ureteral stricture length >2 cm (OR 6.4, 95% C.I. 1.1-36.9, p = 0.04) and concomitant chemotherapy (OR 8.9, 95% C.I. 1.6-49.9, p = 0.01) as predictors of recurrence. At multivariate analysis concomitant chemotherapy was confirmed as an independent predictor of recurrence (OR 7.8, 95% C.I. 1.3-49.0, p = 0.03). Endourological management of an RIUS is reasonable for short and mid-proximal ureteral strictures, while robotics is required in almost all the remaining cases. Up to 15% of recurrence develops within 6 months. Re-do reconstructive surgery is rarely performed, even in referral centers.

Endoscopic injection vs anti-reflux surgery for moderate- and high-grade vesicoureteral reflux in children: a cost-effectiveness international study

Even if vesicoureteral reflux is a common condition in children, there are no guidelines about the best therapeutic approach. This study aims to compare the results of endoscopic injection and ureteral reimplantation in children with grade III, IV and V VUR. A multicenter retrospective study included children with grade III, IV and V VUR treated from 2003 to 2018 at three Departments of Pediatric Surgery. Patients were divided into Group A (endoscopic injections) and Group B (anti-reflux surgery), B1 (open, OUR), B2 (laparoscopic, LUR) and B3 (robot-assisted laparoscopic RALUR). Follow-up was at least 5 years. 400 patients were included, 232 (58%) in group A and 168 (42%) in group B. Mean age at surgery was 38.6 months [3.1–218.7]. Mean follow-up was 177.8 months [60–240]. Group A had shorter operative time than group B (P < 0.01); lower analgesic requirement (p < 0.05), shorter hospital stay (P < 0.05) and lower overall costs (p < 0.05), but higher postoperative PNPs (p < 0.01), lower success rate (p < 0.01) and higher redo-surgery percentage (p < 0.01). No differences in terms of postoperative complications, success rate and mean radiation exposure between the two groups. Endoscopy is associated with shorter operative time, shorter hospitalization and lower cost, also in case of multiple injections. Recurrence rate after surgery is lower meaning lower rate of re-hospitalization and radiation exposure for children.

Primary vesicoureteral reflux.

Primary vesicoureteral reflux (VUR) is one of the most common urological abnormalities in infants and children. The association of VUR, urinary tract infection (UTI) and renal parenchymal damage is well established. The most serious complications of VUR-associated reflux nephropathy are hypertension and proteinuria with chronic kidney disease. Over the past two decades, our understanding of the natural history of VUR has improved, which has helped to identify patients at increased risk of both VUR and VUR-associated renal injury. The main goals in the treatment of paediatric patients with VUR are the prevention of recurrent UTIs and minimizing the risk of renal scarring and long-term renal impairment. Currently, there are four options for managing primary VUR in infants and children: surveillance or intermittent treatment of UTIs with management of bladder and bowel dysfunction; continuous antibiotic prophylaxis; endoscopic subureteral injection of tissue-augmenting substances; and ureteral reimplantation via open, laparoscopic or robotic-assisted surgery. Current debates regarding key aspects of management include when to perform diagnostic imaging and how to best identify the paediatric patients that will benefit from continuous antibiotic prophylaxis or surgical intervention, including endoscopic injection therapy and minimally invasive ureteral reimplantation. Evolving technologies, such as artificial intelligence, have the potential to assist clinicians in the decision-making process and in the individualization of diagnostic imaging and treatment of infants and children with VUR in the future.

A Case of Chronic Back Pain: Revealing Complete Ureteral Duplicity in an Adult Woman

Ureteral duplication is a rare congenital anomaly, often diagnosed incidentally, characterized by the presence of two distinct ureters draining a single kidney. This condition can lead to complications such as vesicoureteral reflux or upper pole obstruction, often due to ectopic ureteral insertion or ureterocele. We report the case of a 40-year-old woman presenting with left-sided chronic low-back pain. Imaging studies, including ultrasound and CT urography, revealed bilateral ureteral duplication with significant left ureterohydronephrosis due to dysplasia and ectopic insertion of the upper ureter. Radiological imaging, especially CT urography, is essential for diagnosing ureteral duplication and identifying its complications. Timely imaging and intervention are critical for preserving renal function, with treatment options depending on the extent of renal impairment. These may include partial or total ureteronephrectomy or ureteral reimplantation.

Transvesicoscopic Cohen Ureteric Reimplantation for Vesicoureteral Reflux in Children: A Pilot Study

Abstract Background Cohen’s pneumovesicoscopic reimplantation technique (CPRT) is a minimally invasive procedure that resembles the surgical steps of the open cross-trigonal reimplantation technique with a similar success rate and the inherent benefits of a minimally invasive approach, like less need for analgesia and less morbidity. Aim of the Work to evaluate the efficacy and safety of CPRT in 20 pediatric patients with primary VUR presented to 2 pediatric surgery departments, in 2 tertiary centers. Patients and Methods a prospective interventional study on 20 children (13 girls, 7 boys, age ranged from 4 to 12 years) with primary vesicoureteral reflux (VUR), grades II-IV (6 bilateral, 9 RT and 5 LT) underwent a CPRT. Suprapubic ports were placed: a 5-mm camera port and two 3- mm working ports. After the ureter(s) have been dissected transvesically a submucosal tunnel is made for ureteric reimplantation to be carried out using 5/0 absorbable sutures. After the procedure, the urethral catheter was taken out two days later, and the patients were released on day three. Clinical evaluation, renal ultrasonography, and voiding cystourethrogram were used to Follow-up the patients. Results 198.5 min was the average operating time (range 90 – 240 min). Two cases developed postoperative complications (mild suprapubic emphysema-perivesical hematoma) managed conservatively. One case needed conversion to open technique because of intraoperative complications (port displacement- perivesical air leakage). All patients had renal US and VCUG between 3 and 6 months after surgery. All low-grade reflux patients (grade II &amp; III) had their hydronephrosis disappear on postoperative US (13 out of 26 refluxing units), while persistence of grade I VUR on VCUG was in two cases (2 units). Conclusion Technically feasible, Cohen’s pneumovesicoscopic reimplantation technique can be carried out safely and effectively in children. It is advisable to select the patients carefully in the primary phase of this technique. Some technical modifications are suggested to overcome the technical obstacles faced, helping us to master this promising technique.

A Systematic Review of Ureteral Reimplantation Techniques in Endometriosis: Laparoscopic Versus Robotic-Assisted Approach.

Introduction: Endometriosis, characterized by the presence of endometrial tissue outside the uterus, includes deep endometriosis (DE), which can affect the urinary tract. Ureteral endometriosis (UE) is a rare but significant manifestation that can lead to ureteral obstruction, hydronephrosis, and potential kidney loss. This systematic review evaluates the effectiveness and outcomes of laparoscopic versus robotic-assisted ureteral reimplantation techniques in patients with UE. Materials and Methods: A systematic literature search was conducted following PRISMA guidelines across PubMed, MEDLINE, Embase, Web of Science, and the Cochrane Library, from inception to July 2024. Studies included patients with UE who underwent ureteral reimplantation using laparoscopic or robotic-assisted techniques. Data on patient demographics, surgical technique, duration of surgery, complications, follow-up duration, and clinical outcomes were extracted and analyzed. Results: Twelve studies met the inclusion criteria, comprising 225 patients in the laparoscopic group and 24 in the robotic-assisted group. Lich-Gregoir ureteral reimplantation, with or without a psoas hitch, was the predominant technique used. The average surgery duration was 271.1 min for the laparoscopic group and 310.4 min for the robotic-assisted group. Recurrence rates for UE were 2.95% for laparoscopic and 5.9% for robotic-assisted procedures. The robotic-assisted group had a significantly shorter hospital stay (6.7 days vs. 9.1 days, p < 0.01). Postoperative complication rates were comparable between the two techniques (p = 0.422). Conclusions: Both laparoscopic and robotic-assisted techniques for ureteral reimplantation in UE are safe and effective, with the choice of technique guided by surgeon expertise and specific clinical scenarios. However, the limited number of robotic cases introduces a bias, despite statistical significance.

Endoscopic balloon dilatation of primary obstructive megaureter: An effective first line management in children

This study evaluates outcomes of endoscopic balloon dilatation (EBD) in the management of primary obstructive megaureter (POM) in children. Retrospective data between 2013 and 2023 from two tertiary paediatric surgical centres in the UK were reviewed. Pre and post-operative clinical and imaging parameters of children managed with EBD were assessed. Failure of procedure was defined as requiring further intervention due to persistent/recurrent symptoms, upper tract dilatation and/or obstruction on MAG3 over the follow up period. 55 children with 61 renal units were evaluated. Median age at treatment was 18 months with a median follow up of 24 months. There was significant reduction in upper tract ultrasound measurements following balloon dilatation but there was no significant difference between the pre and post-operative renal function on MAG3. No significance difference was demonstrated when the outcomes of cutting and non-cutting balloons were compared. No significant difference was shown when outcomes after EBD were compared between infants vs older children as well as ureteric dilatation less than or over 25mm (p=0.841). 87% were successfully treated with a single dilatation and this increased to 95% after second dilatation. The remaining 5% had ureteric re-implantation. Although a retrospective study, the patient population is relatively large. 87% success rate shown after EBD is comparable to similar studies. It has been suggested that children less than 12months and those with severe ureteric dilatation (>25mm) may not be suitable for EBD. No significant difference was demonstrated when the outcomes of these categories of children were compared to other children with POM. All of the patients that had repeat balloon dilatation required no further intervention, a finding that has so far not been well evaluated in available literature. This study demonstrates 87% success rate after single EBD in children with POM and this outcome increased to 95% following a second dilatation. EBD is shown to be an effective definitive surgical management option of POM. It can be safely offered as first line management in all patient groups and repeated if no initial response.

Robot-Assisted Extravesical Ureteral Reimplantation (REVUR) in Pediatric Patients: A New Standard of Treatment for Patients with VUR-A Narrative Review.

Robot-assisted extravesical ureteral reimplantation (REVUR) was described for the first time in 2004. Since then, the surgical approach of vesicoureteral reflux (VUR) has changed dramatically. The benefits of this technique are great when compared to the laparoscopic or traditional open approaches. A literature search of PubMed was performed to identify articles covering any aspect of REVUR in the pediatric population. A total of 108 papers published over the period 2004-2024 were collected. Of these, 40 studies were considered valuable in terms of obtaining a complete overview of the REVUR technique. This review aimed to describe the current state of the art of REVUR and define it as the new standard technique for surgical management of selected patients with VUR.

The Effectiveness of the Surgical Correction of Vesicoureteral Reflux on Febrile Urinary Tract Infections after a Kidney Transplant: A Single-Center Retrospective Study.

Background/Objectives: Vesicoureteral reflux (VUR) is considered one of the major causes of post-renal transplant febrile urinary tract infections (UTI), leading to impaired renal function and the premature loss of the renal graft. We aimed to evaluate whether surgical VUR correction, such as open redo ureteric reimplantation, could be an option for treatment and provide better outcomes in post-transplant care for patients with UTI compared to their pre-VUR correction clinical state. Methods: Our study presents a retrospective analysis of 10 kidney transplant recipients with febrile UTI at the Renal Transplant Service of a Brazilian public hospital from 2010 to 2020. We selected patients who primarily underwent a surgical correction of post-transplant VUR, which was corrected by extravesical reimplantation without a stent in all patients by the same professional surgeon. Results: From 710 patients who received kidney transplants, 10 patients (1.4%) suffered from febrile UTI post-transplant and underwent surgical correction for VUR. Despite the study's limitations, such as its retrospective nature and limited sample size, the efficacy of open extravesical ureteral reimplantation in reducing post-operative febrile UTI in renal transplant patients was observed. Conclusions: As febrile UTI can contribute significantly to patient mortality after kidney transplantation and VUR emerges as a major cause of post-transplant febrile UTI, it is essential to treat it and consider the surgical outcome. This study emphasizes the timely detection and effective treatment of VUR via extravesical techniques to reduce febrile UTI occurrences post-transplant and it contributes insights into the role of surgical interventions in addressing VUR-related complications post-kidney transplantation.

Asymmetrical primary vesicoureteral reflux: Which is the best surgical strategy?

No report has been published regarding the recommended surgical treatment in patients presenting with symptomatic primary asymmetrical vesicoureteral reflux (VUR): high grade on one side and low grade on the contralateral side. The aim of this study was to evaluate the effectiveness and outcome of combined Lich-Gregoir extravesical reimplantation and subureteric Deflux® injection, of high grade and low grade VUR respectively. Non-inferiority to bilateral cross-trigonal reimplantation was investigated in terms of surgical complications, number of post-operative fUTIs and need for re-intervention. A monocentric retrospective study was undertaken of all consecutive children with primary asymmetrical VUR on MCUG treated over an 18-year period (2004-2022). Surgery was indicated following an episode of febrile urinary tract infection despite appropriate non-operative management. Demographic and clinical such as length of hospital stay for pain management, use of urinary Foley catheter and complications were analyzed. A total of 80 children met the study criteria: 40 patients underwent bilateral cross-trigonal re-implantation (Group 1) and 40 patients the combined Lich-Gregoir extra vesical reimplantation and Deflux® sub ureteric injection (Group 2). Complication and success rates were comparable in the two groups. The median hospital stay was significantly shorter for Group 2, with 50% of patients who were discharged on day 1. Moreover, the data showed a significant lesser need in number and length of bladder catheter and ureteral stents in Group 2. The technique proposed overcome the inconveniences of the other procedures that are commonly used in bilateral RVU: difficulty in retrograde catheterization or ureteroscopy after bilateral cross-trigonal reimplantation, the risk of transient bladder dysfunction after bilateral extravesical reimplantation and the low rate of success for high grade reflux of the sub ureteric Deflux® injection. The main limitation of the study lies in its retrospective nature and in the relatively short median follow-up. The combined Lich-Gregoir extra-vesical ureteral reimplantation and sub-ureteric Deflux® injection for the treatment of primary asymmetrical VUR is an effective alternative to the gold standard cross-trigonal ureteral reimplantation. Moreover, the position of the ureteric orifice is not modified in the eventuality of endourological procedures into adulthood.
