Abstract
PURPOSE OF REVIEW To review and describe the recent evolution of surgery for the various types of pediatric megaureter. RECENT FINDINGS Megaureter management first relies on determining the underlying cause, whether by obstruction, reflux, or a combination, and then setting appropriate surgical indications because many cases do not require surgery as shown by observation studies. Endoscopic balloon dilation has been on the rise as a major treatment option for obstructive megaureter, while refluxing megaureters can also be treated by laparoscopic and robotic techniques, whether extravesically or transvesicoscopically. During ureteral reimplantation, tapering is sometimes necessary to address the enlarged ureter, but there are also considerations for not tapering or for tapering alternatives. Endoscopic and minimally invasive surgeries for megaureter have been the predominant focus of recent megaureter literature. These techniques still need collaborative prospective studies to better define which surgeries are best for patients needing megaureter interventions.

J Clin Med 2023; 12:5686. [PMID: 37685751 PMCID: PMC10488379 DOI: 10.3390/jcm12175686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 08/04/2023] [Accepted: 08/29/2023] [Indexed: 09/10/2023] Open
Abstract
BACKGROUND The minimally invasive implementations of the established open methods for the correction of primary vesicoureteral reflux have proven to be successful in terms of feasibility and safety. The aim of this study was to investigate to what extent pediatric patients benefit from vesicoscopic operations. METHODS Between 2010 and 2022, 224 children (359 ureters) underwent ureteral reimplantation for vesicoureteral reflux in our clinic. Children, operated on according to the COHEN technique, underwent an open approach in 39 cases, whereas 151 patients were operated on vesicoscopically. A total of thirty-four children have received a ureteral reimplantation according to the LEADBETTER-POLITANO technique: twenty-nine openly and five vesicoscopically. The open and vesicoscopic groups were compared with regards to perioperative data and postoperative course. RESULTS The mean operating time was significantly shorter for open than for the vesicoscopic procedures in the COHEN group (99 vs. 149 min, p < 0.001). Similarly, a comparison of ureteral reimplantations, according to LEADBETTER-POLITANO, favored the open procedure, although this was not significant (161 vs. 196 min, p = 0.135). There was no significant difference in the recurrence rate of all the groups. All procedures remained within the accepted range with a success rate of at least 96%. In the postoperative course, a significantly shorter hospital stay (4.1 vs. 7.9 days, p < 0.001 for COHEN-patients; 5.6 vs. 9.2 days for LEADBETTER-POLITANO-patients), as well as a significantly lower need for continuous analgesic administration, was observed for the vesicoscopic approaches of both methods (0.8 days in both vesicoscopic groups vs. 3.7 resp. 3.8 days in open groups, p < 0.001). In addition, the time of bladder drainage was significantly shorter in open techniques (7.2 vs. 1.9 days, p < 0.001 for COHEN-patients; 3 vs. 8.7 days for LEADBETTER-POLITANO-patients). CONCLUSIONS For almost all underlying causes, the surgical treatment of vesicoureteral reflux can be performed vesicoscopically, even if bilateral, in one session. Patients benefit significantly from the use of minimally invasive surgery in the postoperative course with faster mobilization, less need for analgesics, a shorter bladder drainage and a reduced hospital stay, compared with its open counterparts.

J Laparoendosc Adv Surg Tech A 2023; 33:417-421.

Abstract
Purpose: Transvesicoscopic ureteral reimplantation (TVUR) for vesicoureteral reflux (VUR) is a technically demanding operation. The technical difficulty is further increased by previous failed endoscopic injection, which causes intense fibrosis around the ureter. In this study, we compared primary TVUR with TVUR after previous failed endoscopic injection for VUR. Materials and Methods: The records of all children undergoing TVUR by a single surgeon over a 4-year period were analyzed. The children were divided into group 1 (primary TVUR, n = 50) and group 2 (TVUR after previous failed endoscopic treatment of Dextranomer/Hyaluronic Acid, n = 7). Demographic, clinical, radiologic, operative and follow-up data were compared between the two groups. The results were analyzed by statistical software; Mann-Whitney test and Fisher's exact test were used where appropriate, and P < .05 was considered significant. Results: Both the groups were comparable with respect to age and mean VUR grade. The mean VUR grade was significantly higher in group 1 and mean operative time per ureter was significantly more for group 2 than group 1. The postoperative hospital stay, success of TVUR, and complications were not significantly different between the groups. Conclusions: To our knowledge, this is the first report of its kind. TVUR after previous failed endoscopic injection could be done safely with good success, but with longer operative time than primary TVUR even in expert hands. Hence, previous failed endoscopic injection is not a contraindication to TVUR.

Abstract
We herein report an extremely rare case of urodynia caused by bladder wall adhesion to the anterior abdominal wall after vesicoscopic ureteral reimplantation for vesicoureteral reflux with resolution of the urodynia by laparoscopic adhesiotomy. A 13-year-old girl who had undergone vesicoscopic cross-trigonal ureteral reimplantation for bilateral grade IV vesicoureteral reflux subsequently experienced severe urodynia for 5 years until her self-report to the attending physician. Magnetic resonance imaging suggested that bladder wall adhesion to the anterior abdominal wall may have caused the urodynia. Therefore, laparoscopic adhesiotomy of the bladder was performed. Notably, her urodynia disappeared immediately after surgery.

Abstract
BACKGROUND New technology attracts necessary concerns regarding safety and effectiveness, including the risk and circumstances of conversions. This study analyses our 11-year experience of conversions from a dedicated pediatric robot-assisted laparoscopic surgery service. METHODS Consecutive patients were evaluated from a prospective database for the period March 2006 to May 2017. Descriptive and quantitative data for conversions were analysed. Variables were investigated including year of surgery, patient age, operation type, surgeon, and experience. RESULTS A total of 539 children underwent 601 procedures. There were 45 different types of procedures. Mean (± SD) age was 7.0 ± 5.2 years, and youngest 4 weeks old. There were 31 conversions (5.8%). Conversion rates were significantly higher in younger children, with rates of 10.0%, 6.1% and 4.2% for age groups 0-2, 2-6, and 6-18 years respectively (p = 0.01). There was a significant difference in conversion rates amongst procedures (p<0.001). Intravesical (9/26, 34.6%), liver cyst (2/8, 25.0%) and choledochal cyst (8/60, 13.3%) procedures were the highest. The most frequent reason for conversion was anesthetic related issues caused by dilated intestine and/or inadequate muscle relaxation (16/31, 52%). Three conversions were attributable to mechanical failures, none attributed to intraoperative complication. CONCLUSIONS Conversion rates are low even in the learning phase and comparable favourably to conventional laparoscopy, supporting the safety and effectiveness of robot-assisted technology for advanced laparoscopy in children. The importance of optimization of surgical conditions cannot be overemphasised.

Abstract
BACKGROUND There are many reports on the application of minimally invasive technology in the correction of children's VUJO, but there is no report on the treatment of children's VUJO by the TU-LESS Lich-Gregoir method. We aimed to comparatively analyze the therapeutic outcomes of transvesicoscopic ureteral reimplantation Cohen procedure (TUR-C) and TU-LESS surgery Lich-Gregoir procedure (TU-LESS-LG) in pediatric VUJO. METHODS The data of 49 children with VUJO admitted from January 2016 to January 2020 were retrospectively analyzed. Based on different surgical methods, they were divided into the TUR-C group (23 cases) and the TU-LESS-LG group (26 cases). The demographic characteristics, perioperative characteristics, postoperative complications, the recovery of renal function, and the improvement of hydronephrosis were compared between the two groups. RESULTS There were no statistical differences in demographic characteristics and preoperative data between the two groups. The TU-LESS-LG group was superior to the TUR-C in terms of average operation time and postoperative hospital stay. There was no statistical difference between the two groups in terms of postoperative complications, postoperative recovery of renal function, and improvement of hydronephrosis. CONCLUSION The two surgical methods can achieve a similar curative effect in the treatment of VUJO. The TU-LESS-LG has more advantages in operation time, postoperative hospital stays, the wider age selection range of cases, megaureter tapering, and cosmetic incision, but the operation is more difficult.

Abstract
For the treatment of vesicoureteral reflux, the introduction of vesicoscopic procedures offers new perspectives for improving patient comfort and quality. Our aim was to examine whether minimally invasive vesicoscopic cross-trigonal ureteral reimplantation (VCUR) would meet expectations. Between 2012 and 2021, 99 girls and 35 boys with high-grade vesicoureteral reflux (VUR) underwent VCUR. For two boys, we failed to establish the pneumovesicum, leading to conversion to open surgery. The mean age was 4.5 years, ranging from 10 months to 18 years. VCUR was successfully performed in 132 patients, including 75 patients with bilateral VUR and 12 children with double ureters with unilateral or bilateral VUR, corresponding to a total of 229 operated ureters. The mean time of operation was 151 min for all patients. There were no perioperative complications, with the exception of three cases of pneumoperitoneum without consequences. Postoperatively, we recognized three cases of acute hydronephrosis, two of them required transient drainage. Three patients developed extravasation of urine after the postoperative removal of the transurethral catheter, rapidly resolved by new drainage. In two patients, we combined VCUR with laparoscopic heminephrectomy and opposite laparoscopic nephrectomy, respectively. Overall, mean postoperative hospital stay was 4.2 days. We observed recurrent VUR in seven ureters, resulting in a success rate for VCUR of 96.9%. These results demonstrate the feasibility of VCUR and its potential to displace open surgery with high safety and wide applicability.

Abstract
Background: Maintenance of the body posture and precise repetitive movements during minimally invasive surgeries predispose the surgeons to the risk of musculoskeletal disorders (MSDs). The present study was designed to estimate the ergonomic risk of MSDs in a single surgeon while performing vesicoscopic ureteric reimplantation. Materials and Methods: All children with primary vesicoureteric reflux (VUR) undergoing vesicoscopic ureteric reimplantation through the laparoscopic (Group 1) or robotic (Group 2) approaches from July 2015 to October 2019 were included. Data, including age at the time of surgery, gender, the severity of VUR (grade), number of ureters involved (unilateral or bilateral), and procedural details, were recorded. Rapid Entire Body Assessment (REBA) tool was used for the ergonomic risk assessment of each procedure. The REBA scores were graded as negligible (1), low (2-3), medium (4-7), high (8-10), and very high (11 or more). The risk index was considered as normal (1 or less) and high (>1). The ergonomic risk associated with both approaches was compared. Results: A total of 16 patients (Male:Female = 9:7) were included in the present study. Groups 1 and 2 had 11 and 5 patients, respectively. The average (range) age of the children belonging to Group 1 was significantly lesser than Group 2 (3 versus 7.5 years; P = .0004). The average duration of surgery was significantly longer in Groups 1 versus 2 (P = .03). The average REBA scores associated with the laparoscopic and robotic approaches were 13 and 5, respectively (P = .0006). The risk indices in both approaches were 3.25 and 1.25, respectively. Conclusion: In a limited cohort of patients, we observed an overall high risk of MSD to the surgeon while performing vesicoscopic ureteric reimplantation. The associated ergonomic risk was significantly less with the robotic (medium risk category) versus laparoscopic approach (very high risk category).

Peadiatric transvesicoscopic dismembered ureteric reimplantation for ectopic upper ureter in duplication anomalies. J Pediatr Urol 2021; 17:412.e1-412.e5.

Abstract
INTRODUCTION Ectopic upper pole ureters in duplex kidneys can be managed surgically by ipsilateral distal ureteroureterostomy or reimplantation of both ipsilateral ureters when upper pole shows reasonable function. OBJECTIVE This study aimed to evaluate the clinical outcomes of transvesicoscopic dismembered upper ureteric reimplantation for patients with ectopic upper pole ureters in duplication anomalies. PATIENTS AND METHODS Between July 2015 and January 2019, laparoscopic transvesicoscopic ureteral reimplantation was performed in 20 patients with ectopic upper pole ureters. An incision was made in the bladder wall at 1.0 cm proximal to the lower ureteral orifice of affected side. The upper pole ureter was recognized, and the terminal portion of the upper ureter was ligated and cut. Then the proximal portion of the upper ureter was mobilized, a transverse submucosal tunnel was created and upper ureteric reimplantation was performed with 6/0 absorbable sutures. Patients were followed up with renal ultrasonography and voiding cystourethrogram for clinical outcomes and hydronephrosis trends. RESULTS Median (range) age at surgery was 22.5 (10-53) months. All of the 20 operations were successful, and none required conversion to an extravesical approach or open surgery. Four patients presented with worsening upper pole hydroureteronephrosis but recovered three to six months postoperatively. Resolution of symptoms and improving hydroureteronephrosis were achieved in all patients and VUR of the upper and lower ureters was not detected at postoperative follow-up. DISCUSSION To our knowledge, dismembered reimplantation of upper pole ureters has been reported only in a small series through extravesical technique. In our study, we performed intravesicoscopic upper ureter Cohen reimplantation for duplex system ureteral ectopia. Compared with the extravesical approach, the transvesicoscopic approach leave most of the pelvic structures intact and the creation of a submucosal tunnel for prevention of ureteral reflux is more reliable; in addition, this approach avoids any manipulation of the lower pole ureter compared to ipsilateral ureteroureterostomy. But this method does not seem applicable to children under 6 months of age because of the small bladder capacity. CONCLUSIONS The laparoscopic intravesical technique of dismembered ureteral reimplantation was safe and feasible in our cases and may be an alternative surgical treatment for ectopic upper pole ureters in duplication anomalies.

Abstract
OBJECTIVE When considering treatment for vesico ureteric reflux via inimally invasive surgery there is a dilemma to choose between laparoscopic extravesical (LEVUR) and transvesicoscopic (TVUR) ureteric reimplantation. In this systematic review and meta-analysis we have analyzed the articles on LEVUR and TVUR and compared the outcomes. METHODS We searched the databases to identify all papers pertaining to TVUR and LEVUR in the pediatric population. Duplicate publications, review articles, incomplete articles and robotic assistance were excluded. Systematic review was performed to identify patient data, reflux grades, laterality, duration of surgery, time to discharge, success rate and complications. Meta-analysis of heterogeneity was reported with I 2 statistics. Once heterogeneity was found low, the pooled outcomes were compared with students t test and Fishers exact test, wherever appropriate. RESULTS After screening a total of 45 articles, 23 articles were included (13 articles on TVUR and 10 articles on LEVUR). The I 2 statistics for TVUR and LEVUR showed low heterogeneity with I 2 of 0% (95% C.I 0-37%) and 25% (95% C.I 0-64%) respectively. With low heterogeneity both were suitable to be considered to have been conducted under similar conditions with possibility of using fixed effect model. The percentage of Grade 5 VUR was significantly higher (p = 0.001; X 2) in TVUR (11.9%) compared to LEVUR (2.2%). The proportion of bilateral reimplantation was significantly higher (p = 0.001; X 2) in TVUR compared to LEVUR (summary table). The success rate of LEVUR was significantly higher at 96.7% compared to TVUR at 93.7% (p = 0.007 X 2). Unilateral/Bilateral TVUR took significantly longer duration of surgery (155/194 min vs 107/161 min) compared to LEVUR (p = 0.001; Fishers). The mean (s.d) time to discharge was longer at 3.2 (1.6) days for TVUR compared to 1.6 (0.4) days for LEVUR (p = 0.001; Fishers). The complication rate was comparable, 7.35% for TVUR and 5.35% for LEVUR (p = 0.167; X 2). DISCUSSION In this meta-analysis we found that LEVUR had shorter operating time, higher success, and shorter hospital stay compared to TVUR. A probable explanation could be higher number unilateral VURs and lower number of grade 5 VUR cases in LEVUR group. Both the techniques had comparable overall complication rate: LEVUR had more post-operative urinary retention while TVUR had more port-related problems.

Abstract
Robotic surgery has been slow to be fully accepted in the world of pediatric urology largely because of its initial application directed towards adult use and because of the inherent high cost associated with it. However, as previously shown, it has now become the gold standard for adolescent pyeloplasty in The United States. As the adoption of robotic surgery in children has become more widespread, its use has been applied to a broader spectrum of procedures with similar success rates to standard laparoscopy. These procedures include nephrectomy, heminephrectomy, ureteral reimplantation, and ureteroureterostomy. However, it has also shown feasibility and comparable success when compared to open surgery in procedures that were previously deemed too complex to be done by standard laparoscopy. For example, bladder neck reconstruction with Mitrofanoff and Malone procedure as well as bladder augmentation. This review objective is to provide an overview of robotic surgery in pediatric urology, with a focus on the more common cases such as pyeloplasty and reimplantation as well as more complex bladder reconstruction procedures.

Abstract
Background: As a relatively new approach, popularity of pneumovesicoscopic surgery is increasing, but slower than expected due to complex nature of the procedure with efforts to overcome the difficult steps of the procedure. Bladder fixation is one of the crucial steps of the procedure. In this study, we present a novel and simple T-bar technique to overcome this difficulty. Methods: We retrospectively evaluated 24 consecutive patients (39 ureters) who underwent pneumovesicoscopic surgery with fixation of the bladder wall between December 2017 and September 2019. Results: Fixation by transabdominal suture (TS) was performed in 3 patients, while fixation by thread loops with needle in 3 and T-bar device in 18. Tearing of the bladder wall was encountered in 2 patients in TS, in 2 patients with thread loop groups, but none in the T-bar group. Conversion to open surgery was necessary in 3 patients in the T-bar group, but only 1 was related with the fixation technique. Conclusions: T-bar technique is an inexpensive and simple solution providing stable and reliable bladder wall and working port fixation during pneumovesicoscopy.

Abstract
Purpose We introduce our novel procedure for transvesicoscopic ureteral reimplantation using the Politano-Leadbetter technique (TVUR-PL). We describe the detailed surgical procedure and report operative outcomes. Materials and Methods We report a retrospective analysis of operative outcomes of TVUR-PL performed in children with vesicoureteral reflux (VUR) from January 2017 to July 2018. The analyzed operative outcomes included patient demographics, operative times, intra- and postoperative complications, indwelling duration of urethral Foley catheter, hospital length of stay, and treatment success. Results A total of 47 patients (17 males, 30 females) underwent TVUR-PL during the study period, including 18 unilateral and 29 bilateral cases (76 ureters). All operations were successfully completed without open conversion. The median operative time was 121 minutes for unilateral cases and 178 minutes for bilateral cases. The median duration of placement of a urethral Foley catheter was 2 days. There were no intra- or postoperative complications. Only one patient (1/47 patients, 2.1%), who had no postoperative VUR on voiding cystourethrography, experienced febrile urinary tract infection during the follow-up period. Conclusions Our novel TVUR-PL technique is a safe and effective minimally invasive surgical treatment option for children with VUR. The main advantage of our new operation is that it allows us to maintain the natural direction of the ureter after surgery.
