[PMID: 39054235 DOI: 10.1016/j.jpurol.2024.07.010] [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: 02/29/2024] [Revised: 05/19/2024] [Accepted: 07/11/2024] [Indexed: 07/27/2024]
Abstract
Laparoscopic ureteral reimplantation has gained increasing popularity in treating pediatric primary vesicoureteral reflux (VUR) and obstructive megaureter (OM). However, it is technically challenging with a relatively low success rate compared to open surgery. Here we designed a hybrid technique which incorporates laparoscopic surgery and pneumovesical ureteral reimplantation. From 2023 February to 2024 February, five boys and four girls underwent the hybrid reimplantation smoothly. There were seven children with VUR and two with OM. Patient age ranged from eight months to ten years. The mean time was 201.5 min (range 155-240 min) for unilateral operation and 260 min for bilateral operation. Follow-up ranged from 6.4 to 18.7 months. All patients remained asymptomatic, with voiding cystourethrogram showing cure or urinary ultrasonography showing significant improvement. In conclusion, the hybrid laparoscopic ureteral reimplantation appeared to be a simple and effective minimally invasive surgery for treating primary VUR and OM in children.

Abstract
OBJECTIVE To evaluate the outcomes of children with vesicoureteral reflux (VUR) and obstructive megaureter (OM) utilizing various laparoscopic and robot-assisted approaches. MATERIALS AND METHODS Retrospective review of all pediatric laparoscopic and robot-assisted cases for lower ureter pathology was performed between 2016-2022 in 13 academic centers worldwide. Five surgical approaches were assessed: LEUR, LVCUR, LDECUR, RALUR, and RADECUR. RESULTS One thousand three hundred forty-three patients (490 boys and 853 girls) with a median age of 30 months (IQR 12-63) were treated at 13 centers. Nine hundred and eight patients (68%) underwent reimplantation due to VUR (unilateral in 818 and bilateral in 90 patients). Four hundred thirty-five (32%) had a surgery due to ureterovesical junction (UVJ) obstruction. Mean length of follow-up was 14 months (IQR 8-33). Median operative time was 202 minutes (IQR 142-220) in the robotic arm compared to 240 minutes (IQR 160-267) in the laparoscopic (P = .45). Intracorporeal excisional tapering was performed in 118 (8%) of the patients. Six patients in the OM group required additional surgery due to progressive obstruction. In the VUR group, 84% underwent voiding cystourethrography postoperatively. 5.6% showed residual reflux. Grade 1-2 Clavien-Dindo complications occurred in 10 patients (0.7%) and 6 (0.4%) in the laparoscopic and robotic arm, respectively. Grade 3 complications occurred in 17 (1.2%) and 8 (0.5%) in both arms, respectively. Surgical success was achieved in 96% of patients. CONCLUSION Laparoscopic and robot-assisted laparoscopic approaches are simple, safe, and effective for treating all grades of VUR and OM. Robot-assisted approach is beneficial in terms of operative time, intracorporeal suturing, and lower complications rate.

Abstract
BACKGROUND The selection of best surgical approach for treatment of vesico-ureteral reflux (VUR) in the pediatric population remains debated. This study aimed to report the results of a multicenter survey about the current trends in surgical management of pediatric VUR. METHODS An online questionnaire-based survey was performed, with participation of six international institutions. All children (age <18 years) affected by primary III-V grade VUR, who were operated over the last 5 years, were included. The incidence of each VUR intervention, patients' demographics and outcomes were analyzed. RESULTS A total of 552 patients (331 girls), with a median age of 4.6 years (range 0.5-17.6), were included. Deflux® injection (STING) was the most common technique (70.1%). The multicenter success rate after single treatment was significantly lower after STING (74.4%) compared with the other treatments (P=0.001). Persistent VUR rate was significantly higher after STING (10.8%) compared with the other treatments (P=0.03). Choosing endoscopy over surgery mean reducing Clavien Dindo grade 2 complications by 5% but increasing redo procedure rate by 7%. STING was the most cost-effective option. CONCLUSIONS This survey confirmed that the choice of the technique remains based on surgeon's preference. Deflux® injection currently represents the first line therapy for primary VUR in children and the role of surgical ureteral reimplantation is significantly reduced. STING reported acceptable success rate, less postoperative complications and lower costs but higher failure and re-operation rates and related costs compared with the other surgical approaches. The adoption of laparoscopy and robotics over open reimplantation remains still limited.

Comparative study of open, laparoscopic and endoscopic treatments of intermediate grade vesicoureteral reflux in children. Surg Endosc 2022; 37:2682-2687. [PMID: 36414870 DOI: 10.1007/s00464-021-08985-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 12/31/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Low-grade vesicoureteral-reflux (VUR) are rather treated by endoscopic injection, whereas open or laparoscopic procedures are mainly performed for high-grade VURs. Management of intermediate grades is controversial and no study focused on grade III to date. This study aims to compare the results of open, laparoscopic, and endoscopic approaches in children with grade III VUR. METHODS A multicenter comparative retrospective study included children with grade III VUR operated for febrile urinary tract infections (UTIs) from 2007 to 2016. Children without UTI, with reflux of other grades, neurological bladder, duplex system, posterior urethral valves, and bladder exstrophy were excluded. Success was defined as no recurrence of febrile UTI and was presented as event-free survival curves. RESULTS Out of 806 children operated of VUR, 171 met the inclusion criteria (114 females). Seventy-seven children (45%) underwent an open Cohen procedure, 35 (21%) a laparoscopic Lich-Gregoir and 59 (34%) a submucosal endoscopic injection according to the centers' preference. The mean follow-up was 64 months (24-132). Groups were not different for age, sex, and circumcision status. Compared to Cohen procedure, recurrences of febrile UTI were more frequent after laparoscopic treatment (p = 0,02, 8/35) and endoscopic treatment (p = 0.001, 16/59). Redosurgery was also more frequent after laparoscopy (n = 2) and endoscopic injection (n = 14) than after open surgery (n = 0, p < 0.001). CONCLUSION Recurrent febrile UTIs and redosurgery are more frequent after endoscopic and laparoscopic procedures in grade III VUR than open reimplantation. Whether the lower morbidity of laparoscopic or endoscopic approaches balances the risk of recurrent febrile UTI remains to be determined for intermediate grade reflux.

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.

Abstract
Currently, minimally invasive surgery (MIS) includes conventional laparo-thoracoscopic surgery and robot-assisted surgery (RAS) or robotic surgery. Robotic surgery is performed with robotic devices, for example the Da Vinci system from Intuitive Surgical, which has a miniaturized camera capable of image magnification, a three-dimensional image of the surgical field, and the instruments are articulated with 7 degrees of freedom of movement, and the surgeon operates in a sitting position at a surgical console near the patient. Robotic surgery has gained an enormous surge in use on adults, but it has been slowly accepted for children, although it offers important advantages in complex surgeries. The areas of application of robotic surgery in the pediatric population include urological, general surgery, thoracic, oncological, and otorhinolaryngology, the largest application has been in urological surgery. There is evidence that robotic surgery in children is safe and it is important to offer its benefits. Intraoperative complications are rare, and the frequency of postoperative complications ranges from 0–15%. Recommendations for the implementation of a pediatric robotic surgery program are included. The future will be fascinating with upcoming advancements in robotic surgical systems, the use of artificial intelligence, and digital surgery.

Abstract
Vesicoureteral reflux (VUR) is associated with increased risks of urinary tract infection, renal scarring and reflux nephropathy. We review advancements over the last two decades in our understanding and management of VUR. Over time, the condition may resolve spontaneously but it can persist for many years and bladder/bowel dysfunction is often involved. Some factors that increase the likelihood of persistence (e.g., high grade) also increase the risk of renal scarring. Voiding cystourethrography (VCUG) is generally considered the definitive method for diagnosing VUR, and helpful in determining the need for treatment. However, this procedure causes distress and radiation exposure. Therefore, strategies to reduce clinicians' reliance upon VCUG (e.g., after a VUR treatment procedure) have been developed. There are several options for managing patients with VUR. Observation is suitable only for patients at low risk of renal injury. Antibiotic prophylaxis can reduce the incidence of UTIs, but drawbacks such as antibiotic resistance and incomplete adherence mean that this option is not viable for long-term use. Long-term studies of endoscopic injection have helped us understand factors influencing use and the effectiveness of this procedure. Ureteral reimplantation is still performed commonly, and robot-assisted laparoscopic methods are gaining popularity. Over the last 20 years, there has been a shift toward more conservative management of VUR with an individualized, risk-based approach. For continued treatment improvement, better identification of children at risk of renal scarring, robust evidence regarding the available interventions, and an improved VUR grading system are needed.

Abstract
Application of laparoscopy in pediatric urology has evolved over more than 30 years coming from a merely diagnostic use for non-palpable testes to "interventional" laparoscopy to extirpative surgery and finally to the era of reconstructive pediatric laparoscopic urology, when in 1995 Peters described the first laparoscopic pyeloplasty in a child. Laparoscopic surgery in pediatric urology became implemented increasingly in the twenty-first century with now present-day applications including the complete variety of all kind of indications for surgery for pediatric urological pathology. This article aims to provide a comprehensive overview of current indications, techniques, and outcomes of laparoscopic transperitoneal surgery of the upper as well as of the lower urinary tract for urological pathology in the pediatric patient population.
