Robotic-Assisted Bladder Neck Procedures for Incontinence in Pediatric Patients

Robot-assisted reconstructive surgery of lower urinary tract in children: a narrative review on technical aspects and current literature

Background and Objective

Robotic approach is used widely for paediatric upper tract urinary reconstruction. This is a narrative review looking at the current status of robotic approach in lower urinary tract reconstruction. The aim of this article is to highlight the important technical aspects of commonly performed robotic lower urinary tract reconstructive surgeries and review the current literature.

Methods

MEDLINE database search was conducted using MeSH terms and Boolean operators from Jan 2000 to Jun 2022. Abstracts were screened to exclude those in languages other than English as also articles pertaining to (I) upper urinary tract surgery, (II) only laparoscopic surgery (not robot-assisted) and (III) non-urological topics. Selected articles were then reviewed and search expanded to include their references with a focus on advanced lower urinary tract reconstruction.

Key Content and Findings

The technical aspects of robotic ureteric reimplantation, continent catheterisable channel and autoaugmentation are discussed in detail. The early outcomes are comparable to open surgery. The true advantage of robotic approach becomes apparent when performing lower urinary tract reconstruction, where space in the pelvis is limited and access is challenging. Only a few centres are currently performing bladder neck surgery and bladder augmentation.

Conclusions

Robotic lower urinary tract reconstruction in children is feasible and safe. Robotic approach offers better access, especially in the limited space within the pelvis. It reduces blood loss and post-operative pain allowing early recovery and discharge. Long-term follow-up with increasing experience could further validate these early observations.

Pediatric robotic urologic procedures: Indications and outcomes

Introduction

Robotic-assisted laparoscopic surgery (RALS) has revolutionized minimally invasive surgery in pediatric urology. The robotic platform allows surgeons to maintain the benefits of laparoscopic surgery while having enhanced three-dimensional view, dexterity, range of motion, and control of high-resolution cameras. In this review, we summarize the indications and recent outcomes for various pediatric urologic RALS procedures to illustrate the current state of robotics in pediatric urology.

Methods

We systematically searched the PubMed and EMBASE databases. We extrapolated and summarized recent evidence on RALS in pediatric urology patients, with an emphasis on indications and outcomes, with regard to the following procedures and search terms: pyeloplasty, kidney stone surgery, partial nephrectomy, nephroureterectomy, ureteral reimplantation, appendico-vesicostomy, augmentation cystoplasty, bladder neck reconstruction, and Malone antegrade continence enema. Additional Medical Subject Headings terms used to augment the search included "Treatment Outcome" and "Robotic Surgical Procedures."

Results

Increasing usage of RALS has shown many benefits in perioperative and postoperative outcomes. In addition, there is growing evidence that robotic procedures in pediatric urology result in similar or better surgical outcomes when compared to the standard of care.

Conclusions

RALS has shown considerable effectiveness in pediatric urologic procedures and may achieve surgical outcomes comparable to the standard approaches of open or laparoscopic surgery. However, larger case series and prospective randomized controlled trials are still necessary to validate the reported outcomes, in addition to cost analyses and studies on the surgical learning curve. We believe that the continuous evolution of robotic platforms will allow for enhanced care and quality of life for pediatric urology patients.

Robotically Assisted Surgery in Children—A Perspective

The introduction of robotically assisted surgery was a milestone for minimally invasive surgery in the 21st century. Currently, there are two CE-approved robotically assisted surgery systems for use and development in pediatrics. Specifically, tremor filtration and optimal visualization are approaches which can have enormous benefits for procedures in small bodies. Robotically assisted surgery in children might have advantages compared to laparoscopic or open approaches. This review focuses on the research literature regarding robotically assisted surgery that has been published within the past decade. A literature search was conducted to identify studies comparing robotically assisted surgery with laparoscopic and open approaches. While reported applications in urology were the most cited, three other fields (gynecology, general surgery, and “others”) were also identified. In total, 36 of the publications reviewed suggested that robotically assisted surgery was a good alternative for pediatric procedures. After several years of experience of this surgery, a strong learning curve was evident in the literature. However, some authors have highlighted limitations, such as high cost and a limited spectrum of small-sized instruments. The recent introduction of reusable 3 mm instruments to the market might help to overcome these limitations. In the future, it can be anticipated that there will be a broader range of applications for robotically assisted surgery in selected pediatric surgeries, especially as surgical skills continue to improve and further system innovations emerge.

Robotics in Pediatric Urology: Evolution and the Future

Almost 30 years have passed since the inception of minimally invasive surgery in urology and specifically in pediatric urology. Laparoscopy has now become an essential tool in the pediatric urologic armamentarium. The application of robot-assisted surgery in pediatrics has allowed for widespread utilization for common reconstructive procedures such as pyeloplasty and ureteral reimplantation. Understanding the implementation, technical considerations, and outcomes are critical for continued success and adoption. This has allowed for increased use in more complex urologic procedures such as redo pyeloplasty, dismembered ureteral reimplantation, catheterizable channel creation, and bladder augmentation.
