Abstract
Introduction Dismembered laparoscopic pyeloplasty (LP) is a well-accepted treatment modality for ureteropelvic junction obstruction (UPJO) in children. However, its efficacy and safety in infants, particularly neonates, remain uncertain. To address this significant knowledge gap, we aimed to compare outcomes between a cohort of neonates and infants undergoing LP vs. open pyeloplasty (OP) at less than 6 months and 6 weeks of age. Material and methods We conducted a retrospective analysis of data from patients who underwent primary pyeloplasty at our institution between 2000 and 2022. Only patients aged 6 months or less at the time of surgery were included, excluding redo-procedures or conversions. Ethical approval was obtained, and data were assessed for redo-pyeloplasty and postoperative complications, classified according to the Clavien-Madadi classification. A standard postoperative assessment was performed 6 weeks postoperatively. This included an isotope scan and a routine ultrasound up to the year 2020. Results A total of 91 eligible patients were identified, of which 49 underwent LP and 42 underwent OP. Patients receiving LP had a median age of 11.4 (1-25.4) weeks, compared to 13.8 (0.5-25.9) weeks for those receiving OP (p > 0.31). Both groups in our main cohort had an age range of 0-6 months at the time of surgery. Nineteen patients were younger than 6 weeks at the time of surgery. The mean operating time was longer for LP (161 ± 43 min) than that for OP (109 ± 32 min, p < 0.001). However, the mean operating time was not longer in the patient group receiving LP at ≤6 weeks (145 ± 21.6) compared to that in our main cohort receiving LP. There was no significant difference in the length of stay between the groups. Four patients after LP required emergency nephrostomy compared to one patient after OP. The rate of revision pyeloplasty in our main cohort aged 0-6 months at surgery was 8% in the patient group receiving LP and 14% in the patient group receiving OP (not significant). Three revisions after LP were due to persistent UPJO, and one was due to stent migration. Only one patient requiring revision pyeloplasty was less than 6 weeks old. Conclusion To our knowledge, this is one of the largest collectives of laparoscopic pyeloplasty performed in infants, and it is the youngest cohort published to date. Based on our experience, LP in neonates and infants under 6 months appears to be as effective as open surgery.

Abstract
Anticipating and addressing unexpected intraoperative events and anatomies are some of the most challenging aspects of pediatric urologic practice; uncontrolled hemorrhage is one of the most anxiety provoking and precarious. The increasing application of the robotic platform in pediatric urology adds another layer of complexity as surgeons are not immediately at the patient's bedside. Should hemorrhage occur in robotic cases, clear communication and seamless coordination between members of the operating room team are paramount to optimize patient safety and minimize errors. This is especially important in pediatric cases for which the margin of error is narrow. Non-technical skills, including leadership, decision-making, situational awareness, stress management, and team-communication, become increasingly critical. While many programs have focused on robotic training, few prepare the operating room team and surgical trainees to manage these unforeseen, emergent intraoperative scenarios. This review discusses the role of a multidisciplinary, in situ robot-to-open conversion simulation program in addressing this educational gap, ways to approach establishing these programs, and potential barriers.

Abstract
INTRODUCTION Ureteropelvic junction obstruction (UPJO) is the most common cause of congenital hydronephrosis. Techniques such as laparoscopic pyeloplasty (LP) have gained in popularity over recent years. Although some retrospective studies have compared minimally invasive reconstructive techniques with open surgery for treatment of UPJO in infants, results remain controversial due to the small sample size in most of these studies. OBJECTIVE To verify whether the benefits of minimally invasive pyeloplasty (MIP) observed in adults and children over 2 years of age also apply to infants. METHODS A systematic review of the literature was performed according to PRISMA recommendations. We searched databases of MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. We excluded studies in which patient cohorts were outside the age range between 1 and 23 months of age (infants). Studies should evaluate at least one of the following outcomes: average hospital stay, operative time, follow-up time, complications, post-surgical catheter use, success rate and reintervention rate. The quality of the evidence was assessed with the ROBINS-I tool. RESULTS In total, 13 studies were selected. 3494 patients were included in the meta-analysis, of whom 3054 underwent OP, while the remaining 440 were part of the group undergoing MIP. The mean difference in hospital days was -1.16 lower the MIP group (95 % CI; -1.78, -0.53; p = 0.0003). Also, our analysis showed a significantly shorter surgical time in the group who underwent OP, with a mean operative time of 119.92 min, compared to 137.63 min in the MIP group (95 % CI; -31.76, -6.27; p = 0.003). No statistically significant between-group differences were found respect to follow-up time, complications, post-surgical catheter use, success rate and reintervention rate. CONCLUSION This systematic review with meta-analysis has shown that laparoscopic/robotic pyeloplasty in infants is a safe technique with similar success rates to open surgery. Nonetheless, randomized clinical trials with longer follow-up are needed to consolidate these results with more robust scientific evidence.

Abstract
PURPOSE OF REVIEW This review aims to provide an in-depth exploration of the recent advancements in robot-assisted laparoscopic pyeloplasty (RALP) and its evolving landscape in the context of infant pyeloplasty, complex genitourinary (GU) anatomy, recurrent ureteropelvic junction (UPJ) obstruction, cost considerations, and the learning curve. RECENT FINDINGS Recent literature highlights the safety and efficacy of RALP in treating the infant population, patients with complex GU anomalies, and recurrent UPJO which were all traditionally managed using the open approach. Cost considerations are evolving, with the potential for RALP to have a lesser financial burden. In addition, the learning curve for RALP is diminishing due to robust training programs and advances in research. RALP has become the gold standard in the treatment of UPJO in pediatric urology at many children's hospitals. Surgeon comfort and research in this space allow safe and successful reconstruction in the most challenging of cases.

Abstract
Background To compare the perioperative outcomes and success rates of minimally invasive pyeloplasty (MIP), including laparoscopic and robotic-assisted laparoscopic pyeloplasty, with open pyeloplasty (OP) in infants. Materials and Methods In September 2022, a systematic search of PubMed, EMBASE, and the Cochrane Library databases was undertaken. The systematic review and meta-analysis were conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, with the study registered prospectively in the PROSPERO database (CRD42022359475). Results Eleven studies were included. Dichotomous and continuous variables were presented as odds ratios (OR) and standard mean differences (SMD), respectively, with their 95% confidence intervals (CI). Compared to OP, a longer operation time and shorter length of stay were associated with MIP (SMD: 0.96,95% CI: 0.30 to 1.62, p = 0.004, and SMD: -1.12, 95% CI: -1.82 to -0.43, p = 0.002, respectively). No significant differences were found between the MIP and OP in terms of overall postoperative complications (OR:0.84, 95% CI: 0.52 to 1.35, p = 0.47), minor complications (OR: 0.76, 95% CI: 0.40 to 1.42, p = 0.39), or major complications (OR: 1.10, 95% CI: 0.49 to 2.50, p = 0.81). In addition, a lower stent placement rate was related to MIP (OR: 0.09, 95% CI: 0.02 to 0.47, p = 0.004). There was no statistical difference for success rate between the MIP and OP (OR: 1.35, 95% CI: 0.59 to 3.07, p = 0.47). Finally, the results of subgroup analysis were consistent with the above. Conclusions Our meta-analysis demonstrates that MIP is a feasible and safe alternative to OP for infants, presenting comparable perioperative outcomes and similar success rates, albeit requiring longer operation times. However, it is essential to consider the limitations of our study, including the inclusion of studies with small sample sizes and the combination of both prospective and retrospective research designs.

Abstract
Robotic pyeloplasty has become a natural progression from the development of open, then laparoscopic procedures to treat pediatric patients with ureteropelvic junction obstruction (UPJO). Robotic-assisted pyeloplasty (RALP) is now considered a new gold standard in pediatric MIS. A systematic review of the literature retrieved from PubMed and published in the last 10 years (2012-2022) was performed. This review underlines that in all children except the smallest infants, where the open procedure has benefits in terms of duration of general anesthetic and there are limitations in the size of instruments, robotic pyeloplasty is becoming the preferred procedure to perform in patients with UPJO. Results for the robotic approach are extremely promising, with shorter operative times than laparoscopy and equal success rates, length of stay and complications. In case of redo pyeloplasty, RALP is easier to perform than other open or MIS procedures. By 2009, robotic surgery became the most used modality to treat all UPJO and continues to grow in popularity. Robot-assisted laparoscopic pyeloplasty in children is safe and effective with excellent outcomes, even in redo pyeloplasty or challenging anatomical cases. Moreover, robotic approach shortens the learning curve for junior surgeons, who can readily achieve levels of expertise comparable to senior practitioners. However, there are still concerns regarding the cost associated with this procedure. Further high-quality prospective observational studies and clinical trials, as well as new technologies specific for the pediatric population, are advisable for RALP to reach the level of gold standard.

Abstract
As robotic-assisted (RAL) surgery expanded to treat pediatric congenital disease, infant anatomy and physiology posed unique challenges that prompted adaptations to the technology and surgical technique, which are compiled and reviewed in this manuscript. From the beginning, collaboration with anesthesia is critical for a safe, efficient case including placement of an endotracheal tube rather than a laryngeal mask (LMA) and placement of a nasogastric tube and/or rectal tube to relieve distended stomach or bowel, respectively. Furthermore, end-tidal CO2 (EtCO2 ) is important for monitoring and predicting the effects of pneumoperitoneum on caridiovascular physiology, incranial pressure, and risk of acidosis and hypercarbia. Positioning can further exacerbate these effects and affect intra-abdominal working space. For infant robotic pyeloplasty and heminephrectomy, a "beanbag" is commonly used for stabilization in the lateral decubitus position. We advise against the use of a "baby bump" because it brings the bowels and vasculature more anterior than expected. Pnuemoperitoneum pressure of 8-10 mmHg during port placement maximizes safety, but thereafter, the pneumoperitoneum pressure can be minimized to 6-8 mmHg during the procedure without compromising the visual field. Port sites should be marked after insufflation, followed by the open Hasson technique for peritoneal access and port placement under direct vision with intussusception of the trocars to avoid vascular or bowel injury. Additional tips can be obtained through this manuscript, immersive fellowships, and mini-fellowships. Ulitmately, infant robotic surgery has the potential to benefit many children but is presently limited by the lack of pediatric-specific robotic technology and its associated costs.

Abstract
The uptake of robot-assisted surgery has continuously grown since its advent in the 1990s. While robot-assisted surgery is well-established in adult surgery, the rate of uptake in paediatric surgical centres has been slower. The advantages of a robot-assisted system, such as improved visibility, dexterity, and ergonomics, could make it a superior choice over the traditional laparoscopic approach. However, its implementation in the paediatric surgery arena has been limited primarily due to the unavailability of appropriately sized instruments as per paediatric body habitus, therefore, requiring more technologically advanced systems. The Versius surgical robotic system is a new modular platform that offers several benefits such as articulated instruments which pass through conventional 5 mm ports, compact arms for easier manoeuvrability and patient access, the ability to mimic conventional port placements, and adaptive machine learning concepts. Prior to its introduction to paediatric surgery, it needs to go through a careful pre-clinical and clinical research program.

Abstract
BACKGROUND Since the development of minimally invasive surgery (MIS), laparoscopic and robotic approaches have been widely adopted. However, little has been published detailing the learning curve of MIS, especially in infants. OBJECTIVE To quantify the learning curve of laparoscopic (LP) and robot-assisted laparoscopic pyeloplasty (RAL-P) for treatment of uretero-pelvic junction obstruction (UPJO) in infants evidenced by number of cases, operative time, success and complications. PATIENTS AND METHODS Between 2009 and 2017, we retrospectively reviewed pyeloplasty cases for treatment of UPJO in infants at three academic institutions. The primary outcome was success. Secondary outcomes were UPJO recurrence, complications, and operative time as a surrogate of skill acquisition. Continuous variables were analyzed by t test, Welch-test, and one-way ANOVA. Non-continuous variables were analyzed by Chi-squared test or Fisher's exact test. Learning curves (LC) were studied by r-to-z transformation and CUSUM. RESULTS Thirty-nine OP, 26 LP, and 39 RAL-P had mean operative times (OT) of 106, 121, and 151 min, respectively. LCs showed plateau in OT after 18 and 13 cases for LP and RAL-P, respectively. RAL-P showed a second phase of further improvements after 37 cases. At 16 months follow-up, there were similar rates of success and complications between the three groups. CONCLUSIONS Despite different duration of learning phases, proficiency was achieved in both LP and RAL-P as evidenced by stabilization of operative time and similar success rates and complications to OP. Before and after achievement of proficiency, LP and RAL-P can be safely learned and implemented for treatment of UPJO in infants.

Abstract
INTRODUCTION The historical gold standard treatment for ureteropelvic junction obstruction (UPJO) was the open Anderson-Hynes dismembered pyeloplasty (OP). Minimally invasive surgery (MIS) procedures, including laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP), have been reported to achieve better outcomes (i.e., decreased morbidity, reduced postoperative pain, superior esthetic results, and shortened length of hospital stay, LOS), with a success rate similar to OP. The main limitation of the MIS approach is the age and weight of patients, limiting these procedures to children >1 year. This study aims to evaluate the feasibility and benefits of MIS pyeloplasty compared to OP to surgically treat UPJO in children <1 year of age. MATERIALS AND METHODS A systematic review was independently performed by two authors. Papers comparing both techniques (MIS pyeloplasty vs. OP) in infants were included in the meta-analysis. Data (mean ± DS or percentage) were analyzed using Rev.Man 5.4 A p < 0.05 was considered significant. RESULTS Nine studies (eight retrospective and one prospective) meet the inclusion criteria. A total of 3,145 pyeloplasties have been included, with 2,859 (90.9%) OP and 286 (9.1%) MIS. Age at operation was 4.9 ± 1.4 months in OP vs. 5.8 ± 2.2 months in MIS, p = ns. Weight at surgery was 6.4 ± 1.4 kg in OP vs. 6.9 ± 1.4 kg in MIS, p = ns. Operative time was 129.4 ± 24.1 min for OP vs. 144.0 ± 32.3 min for MIS, p < 0.001. LOS was 3.2 ± 1.9 days for OP vs. 2.2 ± 0.9 days for MIS, p < 0.01. Postoperative complications were present in 10.0 ± 12.9% of OP vs. 10.9 ± 11.6% in MIS, p = ns. Failure of surgery was 5.2 ± 3.5% for OP vs. 4.2 ± 3.3% for MIS, p = ns. CONCLUSION The development of miniaturized instruments and technical modifications has made MIS feasible and safe in infants and small children. MIS presented a longer operative time than OP. However, MIS seemed effective for treating UPJO in infants, showing shortened LOS compared to OP. No differences have been reported with regard to the incidence of postoperative complications and failure of pyeloplasty. Given the low quality of evidence of the meta-analysis according to the GRADE methodology, we would suggest limiting MIS procedures in infants to only those high-volume centers with experienced surgeons.

Abstract
INTRODUCTION To perform a systematic review and meta-analysis of outcomes of robotic-assisted laparoscopic pyeloplasty for UPJ obstruction in children. EVIDENCE ACQUISITION A systematic review of the English-language literature on surgical techniques and perioperative outcomes of robotic-assisted laparoscopic pyeloplasty for UPJ obstruction in children was performed without time filters using the MEDLINE (via PubMed), EMBASE, and Cochrane databases in July 2020 according to the PRISMA statement recommendations. EVIDENCE SYNTHESIS Overall, 58 studies were selected for qualitative analysis, 46 of which were included in the meta-analysis. Nearly all studies included were observational and retrospective, either cohort or case-control. The quality of evidence was assessed using Modified Newcastle Ottawa Scoring, with the majority of studies scoring medium or high quality. The mean success rate was 95.4% (CI 91.0-99.3%), over a wide age range. There was a noticeable heterogeneity in reported follow up length and definitions of success rate. The majority of studies reported length of stay of ~1 day. The mean overall complication rate was 12%. For studies that reported complication rate by grade, the mean low Clavien grade (grade 2 or less) complication rate was 9.3% and the mean high Clavien grade (grade 3 or more) complication rate was 6.5%. CONCLUSIONS Robotic assisted surgery is technically feasible and has been shown to achieve very favorable outcomes for pyeloplasty in children. The evidence however is mostly retrospective and from single sites, which introduces potential biases. Further research is needed to further elucidate RALP benefits compared to the open and laparoscopic approach. As a RCT may not be practical in this space, perhaps a prospective multi-institutional design with a uniform reporting system of pediatric RALP is the next step to define its benefits and limits.

Abstract
OBJECTIVE While there are several reports confirming the safety and efficacy of laparoscopic pyeloplasty (LP) and robot-assisted laparoscopic pyeloplasty (RALP) in children there have been none comparing LP and RALP specifically in infants. In this meta-analysis, we have compared the outcomes of LP and RALP in infants. METHODS Pubmed (Medline), Publon, Index Medicus and Embase were searched using the search terms: pyeloplasty (laparoscopic OR robot-assisted) AND (infant), to identify all papers pertaining to LP and RALP. Systematic review was performed to identify information regarding number of patients/renal units, age, body weight, operating time, hospital stay, success and complications. Meta-analysis of heterogeneity was reported with I2statistics. Once heterogeneity was found low, the pooled outcomes were compared with student's t test and Fishers exact test, wherever appropriate. RESULTS After screening a total of 267 articles, 18 articles were included (10 articles on LP, 7 on RALP, 1 reporting both), comprising 323 renal units for LP and 173 renal units for RALP. With low heterogeneity (I2: 0%) both groups were considered to have been conducted under similar conditions for fixed effect model. There was no significant difference between the success rates of LP or RALP (97.5% vs 94.8%; p = 0.21). The mean age at operation was significantly lower for LP (5.6 ± 1.8 months) than RALP (7.2 ± 1.2 months, P = 0.0001). The duration of surgery was 137 ± 45 min for LP while significantly higher at 179 ± 49 min for RALP (p = 0.0001). The mean (s.d) time to discharge was 2.0 (1.9) days for LP while 1.3 (0.4) days for RALP. The overall complication rate was significantly higher (summary table) for RALP than LP (p = 0.03), mainly due to more port-site hernias in RALP. DISCUSSION In the present study, we found that the success of LP and RALP in infants was similar. RALP in infants had longer duration of surgery, similar hospital stay and higher Clavien-3 complications than LP. While several studies have reported favorable outcomes for RALP over LP in children, this was not the case in infants. The smaller workspace, in an infant, can significantly limit the mobility of robotic instruments and increase the chance of port-site conflicts or trocar collisions. The use of larger robotic ports and instruments in the small space of infant abdomen might have been responsible for higher complications in RALP, including significantly larger number of port-site hernias. This meta-analysis represents the early experience of most RALP in infants, and it is possible that with experience RALP outcomes in infants also will catch up with LP. Miniaturization of robotic instruments might render RALP the future standard of care for pyeloplasty in infants.

Abstract
BACKGROUND Since its first description, multiple reports proved efficacy and safety of the robotic platform. Further progress has been made allowing for the application of robotic surgery to smaller patients, including infants. Despite the early favorable results, the use of robot surgery in infants is still controversial and more studies are needed to confirm its benefits. OBJECTIVE To our knowledge, we present the largest single-institution case series of robot-assisted laparoscopic pyeloplasty (RAL-P) in infants, aiming to contribute to the current literature with a guide for key technical steps and safety tips for infant RAL-P. DESIGN, SETTING, AND PARTICIPANTS We performed a retrospective review of a prospectively maintained database. The study protocol was approved by the institutional review board. SURGICAL PROCEDURE Only infants (≤12 mo of age) with a diagnosis of congenital ureteropelvic junction obstruction (UPJO) undergoing primary robotic dismembered pyeloplasty were included in the study. MEASUREMENTS We critically reviewed the clinical outcomes, described the main steps of the operation, and shared tips for a safe approach. RESULTS AND LIMITATIONS From January 2012 to August 2019, 44 infants underwent RAL-P for UPJO--33 (75%) males and 11 (25%) females. All robotic cases were completed successfully, with no laparotomic conversions. The median age and weight were 4 (1-12) mo and 6.8 (3.8-10.5) kg, respectively. The mean operative time was 142 (±25) min. The mean estimated blood loss was 7 (±3.6) ml, and no intraoperative complications occurred. The mean length of hospital stay (LOS) was 1.4 (±0.7) d. Seven (15.6%) patients had postoperative complications-one (2%) ileus (Clavien-Dindo grade [CDG] I), four (9%) urinary tract infections (CDG II), and two (4.5%) port-site hernias (CDG III). At a median follow-up of 19 mo, the success rate was 100%. CONCLUSIONS Given the successful outcomes, benefits of decreased LOS, and improved cosmesis, RAL-P is an appealing management option for UPJO in infants. Market release of new systems, further miniaturization of instruments, and more affordable costs will hopefully be shedding light on more complex applications. PATIENT SUMMARY Infants (≤12 mo of age) diagnosed with ureteropelvic junction obstruction undergoing primary robotic dismembered pyeloplasty were selected and included in this study. No intraoperative complications or conversion to an open approach occurred. Seven patients (16%) developed postoperative complications-one (2%) postoperative ileus, four (9%) urinary tract infections, and two (4.5%) port-site hernias. At a median follow-up of 19 (7-66) mo, the success rate was 100%.

Abstract
The novel technology of robotic-assisted surgery (RAS) has been utilized in children for the past two decades with several potential clinical benefits including reduction of postoperative pain, shortened hospital length of stay, and improved cosmetic outcomes. While associated costs and the limitations regarding instruments for smaller pediatric patients remain relevant issues, surgeon comfort related to ergonomic design in combination with enhanced three-dimensional high-fidelity imaging and tissue handling compared to traditional minimally invasive approached may offer improved surgical and postoperative outcomes. Given that the demand for this innovative technology will likely continue to expand in the field of pediatric surgery, pediatric anesthesiologists will be called upon to provide anesthetic care to patients exposed to this novel surgical technology with its unique features, intraoperative requirements, and potential complications. The current manuscript provides a narrative review of robotic-assisted surgery and discusses important anesthetic considerations and potential complications of these techniques.

Abstract
Robot-assisted laparoscopic surgery (RALS) has recently been described in children < 1 year old. However, little data exist on robotic utilization in infants ≤ 6 months old, likely due to concerns for limited intraabdominal space and decreased distance between ports in this cohort. We hypothesized that the robotic approach can be successfully used for infants ≤ 6 months old. A prospectively collected database of patients undergoing urologic robotic surgery at our institution was reviewed. Patients ≤ 6 months and ≥ 4 kg were included. Patient demographics, intraoperative details, hospital length of stay, and complications were reviewed. Descriptive statistics were performed. Twelve patients ≤ 6 months old underwent urologic robotic surgery by three surgeons at our institution (2013-2019): pyeloplasty (6), ureteroureterostomy (4), heminephrectomy (1), and nephrectomy (1). Median age at surgery was 4.75 months (IQR 4, 6). Median weight was 7.09 kg (IQR 6.33, 7.78). Median console time was 105 min (IQR 86, 123). For all procedures, 8-mm robotic arm ports were used. No procedures were converted to open. Median post-operative hospital stay was 24 h (IQR). Febrile UTI was the only complication occurring within 30 days of surgery (n = 4, 33%; 7-20 days, Clavien grade 2). For those undergoing pyeloplasty or ureteroureterostomy (n = 10), postoperative ultrasound showed improved (n = 9) or stable hydronephrosis (n = 1). At a median follow-up of 19.73 months (IQR 4.27, 38.32), no patient required an unplanned secondary intervention. Robotic upper urinary tract surgery is feasible and safe in patients ≤ 6 months of age and can be performed successfully with the same technique as for older children.

Abstract
Objective: To investigate the outcomes of minimally invasive approach to infants with ureteropelvic junction (UPJ) obstruction by comparing the two surgical modalities of robot-assisted laparoscopic pyeloplasty (RALP) and laparoscopic pyeloplasty (LP). Methods: We conducted a retrospective review of all consecutive infants aged ≤12 months who underwent either LP or RALP in a single institution over the period of 2008-Jul 2020. We included primary pyeloplasty cases that were performed by or under the supervision of the same surgeon. Results: Forty-six infants (LP = 22; RALP = 24) were included with medians of age and body weight at 6 months (2-12months) and 8.0 kg (5.4-10 kg), respectively. There was no difference between the two groups in the patients' demographics and pre-operative characteristics. All infants underwent LP or RALP successfully without conversion to open surgery. None had intraoperative complications. Operative time (OT) was 242 min (SD = 59) in LP, compared with 225 min (SD = 39) of RALP (p = 0.25). Linear regression analysis showed a significant trend of decrease in OT with increasing case experience of RALP(p = 0.005). No difference was noted in the post-operative analgesic requirement. RALP was associated with a shorter hospital length of stay than LP (3 vs. 3.8 days; p = 0.009). 4/22(18%) LP and 3/24(13%) RALP developed post-operative complications (p = 0.59), mostly minor and stent-related. The success rates were 20/22 (91%) in LP and 23/24 (96%) in RALP (p = 0.49). Conclusions: Pyeloplasty by minimally invasive approach is safe and effective in the infant population. RALP may have superiority over LP in infants with its faster recovery and a more manageable learning curve to acquire the skills.

Abstract
Robotic surgery is gaining wider utility in adults; however, few reports have addressed the applicability of robotic surgery for renal tumors in children. The aim of this report is to share our experience in an 8-year-old child with metanephric stromal tumor. To our knowledge, besides being a rare tumor, this is the youngest case reported in the literature whose kidney tumor has been successfully removed with robotic partial nephrectomy. There is a worldwide tendency to perform minimal invasive surgery for kidney tumors. In the presence of an experienced team and proper conditions, we believe that robotic partial nephrectomy will be the preferred option in future.

Abstract
INTRODUCTION Robotic pediatric urologic surgery has gained wide-spread adoption over the last decade. This article describes our experience in instituting the first pediatric urologic robotic surgery program in Canada. We evaluated the feasibility and safety of instituting pediatric robot-assisted urologic surgery and report our early outcomes for robot-assisted pyeloplasty (RAP) and ureteric reimplantation (RUR). METHODS We prospectively evaluated all patients undergoing RAP and RUR by a single surgeon from June 2013 to March 2019. Demographic and clinical data were prospectively collected and included sex, age, and preoperative grade of hydronephrosis or reflux. Descriptive statistics were performed, and comparisons were made using Student's t-tests where appropriate. Success was defined as resolution or significant improvement of hydronephrosis following RAP and absence of recurrent urinary tract infection (UTI) and/or persistent vesicoureteric reflux (VUR) following RUR. Complications were described using the Clavien-Dindo system. RESULTS A total of 52 RAPs and 24 RURs were performed with a minimum of six months followup. Forty-five RAP patients met criteria for success, while diagnostic imaging of success in the form of MAG-3 Lasix renograms was documented in the remaining seven for an overall success of 100%. Sixteen RUR patients met criteria for success and seven showed resolution of VUR on imaging following their first UTI, for an overall success rate of 96%. Operative times progressively improved from 204±35 minutes to 121±15 minutes in the RAP group and from 224±52 to 132±39 minutes in the RUR group. In the RAP cohort, one Clavien grade II and four Clavien grade III complications were noted, while three Clavien grade III complications were noted in the RUR cohort. CONCLUSIONS Despite limited case volumes, robotic pediatric urologic surgery can be integrated into the Canadian healthcare system with success rates comparable to reported literature. However, compared to open surgery, RAP, and especially RUR, warrant further study to ensure lack of significant complications noted in our study.

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
Introduction: Although laparoscopic urachal excision in children has been well reported, there are limited data on a robot-assisted surgery (RAS) approach. The hidden incision endoscopic surgery (HIdES) technique is an established method of eliminating visible scars following a number of RAS urologic procedures. We report our experience of using a robotic approach to treat urachal anomalies in children, and we present the first description of utilizing the HIdES port configuration for this procedure. Materials and Methods: We retrospectively reviewed pediatric patients who underwent resection of a urachal remnant at our institution from 2013 to 2018. Surgical techniques were either the traditional open approach (OA) or RAS. HIdES trocar placement configuration was employed in all robotic cases. Patient demographics, perioperative data, pathology reports, and outcomes were abstracted and compared. Results: Twenty-three patients underwent a urachal remnant resection in the study period (RAS: 14 patients vs OA: 9 patients). RAS patients were older (8.5 vs 2.0 years, p = 0.031) and weighed more than OA patients (36.1 vs 13.9 kg, p = 0.063). Median operative time for RAS was longer than OA operative time (136 vs 33 minutes, p < 0.01). Fewer RAS patients were outpatient compared with OA (7.1% vs 66.7%, p < 0.01), but with a median length of stay of 1 day (0-1 day). Two patients (14.3%) in the RAS group experienced postoperative complications within 1 week of the procedure compared with 1 (11.1%) in the OA group. There was no significant difference in blood loss, postoperative narcotic requirements, or duration of follow-up between both groups. Conclusion: RAS is a safe and feasible alternative to open surgery for urachal anomalies. Complete excision can be achieved by using HIdES port configuration, allowing for excellent cosmetic outcomes that are superior to traditional surgical scars without limitation to essential surgical ergonomics.

J Pediatr Urol 2020; 16:109.e1-109.e6. [PMID: 31806424 DOI: 10.1016/j.jpurol.2019.10.023] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Accepted: 10/24/2019] [Indexed: 01/10/2023]
Abstract
INTRODUCTION To investigate the influence of the body weight on peri- and postoperative outcome in a series of pediatric patients with a diagnosis of uretero-pelvic junction obstruction (UPJO) treated with robot-assisted laparoscopic pyeloplasty (RALP) at a single tertiary referral center. OBJECTIVE In this study, outcomes of RALP in children divided according to the weight are evaluated. STUDY DESIGN Sixty-one consecutive patients treated with RALP from January 2016 to May 2019 were recorded retrospectively and divided according to their weight: group A < 15 kg, group B ≥ 15 kg and were included in this study. Eligible criteria for surgery were symptomatic UPJO, worsening of hydronephrosis, or obstructive pattern at renogram. Success criteria were the reduction of the hydronephrosis at imaging and the absence of flank pain. All procedures were performed by one expert robotic surgeon. RESULTS 18 patients were included in group A (median weight 12 kg) and 43 patients in group B (median weight 33 kg). The median (IQR) operative was 95 (90-120) for group A compared to 90 (85-110) of control group. No significant difference has been found (P = 0.93). We registered one (5.6%) Clavien 3b complication (omental hernia after removal of the drainage requiring surgical correction) and two (4.7%) Clavien 2 complication in group B (urinary infections). No difference has been found in the length of hospital stay, length of catheterization, and duration of procedure between the groups (P > 0.05). At a median follow-up of 23 months (IQR 9-27 vs 9-33), the success rate was comparable between the two groups (94.4% vs 97.7%; P = 0.51). Relapse was recorded in one child per group and both required nephrostomy placement. DISCUSSION Our study tried to fill the gaps in the evidence on the feasibility of RALP in low-weight children reporting favorable peri-operative and long-term outcomes; however, this study shows some intrinsic limitations. The relatively small numbers of patients in the <15 kg may have underpowered the comparison with heavier patients. Moreover, only two patients were <10 kg so that no definitive conclusions on the safety and feasibility of RALP in this cohort of patients can be drawn. CONCLUSION RALP in children <15 kg was feasible and effective to treat UPJO with superimposable results to heavier counterparts. In our experience, the need for a different trocar placement and limited space in patients <15 kg did not affect peri-operative and functional outcomes.

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. [PMID: 31955989 DOI: 10.1016/j.jpedsurg.2019.12.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 11/22/2019] [Accepted: 12/23/2019] [Indexed: 11/24/2022]
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
INTRODUCTION Robotic surgery has been increasingly used in fashioning various surgical anastomoses. Our aim was to collect and analyze outcomes related to anastomoses performed using a robotic approach and compare them with those done using laparoscopic or open approaches through meta-analysis. METHODS A systematic review was conducted for articles comparing robotic with laparoscopic and/or open operations (colectomy, low anterior resection, gastrectomy, Roux-en-Y gastric bypass (RYGB), pancreaticoduodenectomy, radical cystectomy, pyeloplasty, radical prostatectomy, renal transplant) published up to June 2019 searching Medline, Scopus, Google Scholar, Clinical Trials and the Cochrane Central Register of Controlled Trials. Studies containing information about outcomes related to hand-sewn anastomoses were included for meta-analysis. Studies with stapled anastomoses or without relevant information about the anastomotic technique were excluded. We also excluded studies in which the anastomoses were performed extracorporeally in laparoscopic or robotic operations. RESULTS We included 83 studies referring to the aforementioned operations (4 randomized controlled and 79 non-randomized, 10 prospective and 69 retrospective) apart from colectomy and low anterior resection. Anastomoses done using robotic instruments provided similar results to those done using laparoscopic or open approach in regards to anastomotic leak or stricture. However, there were lower rates of stenosis in robotic than in laparoscopic RYGB (p=0.01) and in robotic than in open radical prostatectomy (p<0.00001). Moreover, all anastomoses needed more time to be performed using the robotic rather than the open approach in renal transplant (p≤0.001). CONCLUSION Robotic anastomoses provide equal outcomes with laparoscopic and open ones in most operations, with a few notable exceptions.

Robot-assisted laparoscopic pyeloplasty in infants and children: is it superior to conventional laparoscopy? World J Urol 2019; 38:1827-1833. [PMID: 31506749 DOI: 10.1007/s00345-019-02943-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Accepted: 08/30/2019] [Indexed: 12/11/2022] Open
Abstract
INTRODUCTION Open pyeloplasty (OP) has been the first-line treatment for ureteropelvic junction obstruction (UPJO) since it was first described by Anderson and Hynes. The use of minimally invasive surgery (MIS) to treat UPJO in the pediatric population has increased in recent years, due to decreased morbidity and shorter recovery times. Recently, robot-assisted laparoscopic pyeloplasty (RALP) has seen a steady expansion. Unlike laparoscopic pyeloplasty (LP), RALP comes with a more manageable learning curve aided by specialized technological advantages such as high-resolution three-dimensional view, tremor filtration with motion scaling, and highly dexterous wrist-like instruments. With this review, we aim to highlight the trend toward robotic pyeloplasty over laparoscopy and current available evidence on outcomes. METHODS We systematically searched the PubMed and EMBASE databases, and we critically reviewed the available literature on the use of laparoscopy and robotic technology in pediatric patients with UPJO. RESULTS Overall, we selected 19 original articles and 5 meta-analyses. The available literature showed that the robotic approach to the UPJO allowed for decreased operative times, shorter length of hospital stay, lower complication rates, with success rates comparable to LP. Conflicting results persist regarding robotic platform and equipment costs. CONCLUSION While laparoscopy requires advanced skills for complex reconstructive procedures, such as pyeloplasty, robot-assisted surgery offers the valuable potential of making MIS more accessible to these types of procedure. Robotic technology has contributed to shortening the learning curve by acting as a bridge between open and endoscopic approach. There is still a strong need for higher quality evidence in the form of prospective observational studies and clinical trials, as well as further cost-effectiveness analyses. As robotic surgical technology spreads, future systems will be developed, offering smaller and more flexible tools, allowing enhanced applications on pediatric patients.

Considerations regarding pain management and anesthesiological aspects in pediatric patients undergoing minimally invasive surgery: robotic vs laparoscopic-thoracoscopic approach. J Robot Surg 2019; 14:423-430.

Abstract
In the last decade, the applicability of robotic surgery has been demonstrated in many interventions, expanding the indications of minimally invasive surgery also to pediatrics. The aim of the study is to evaluate postoperative pain to demonstrate better control following robotic procedures compared to thoraco-laparoscopic surgery. An observational, retrospective, multicentre study was performed involving 204 children undergoing robot-assisted surgery and thoraco/laparoscopic surgery at the Istituto Giannina Gaslini in Genoa and the Siena University Hospital (2013-2017): 83 children underwent robotic-assisted surgery and 121 thoracic-laparoscopic surgery. Personal data and type of intervention were assessed, dividing the patients into four categories: thoracic, gastrointestinal, hepatobiliary and urological surgeries. We analyzed the anesthetic risk according to ASA classification by type of intervention, the type of anesthesia used, the anesthetic drugs used during surgery and in the postoperative period. Both the problems that occurred during the procedures and the number of interventions converted into open during robotic surgery and laparoscopic thoracic surgery were analyzed. Pain was measured on the 1st, 2nd and 3rd day (FLACC or NRS scales). By comparing the two groups (robotics-non-robotics), the analysis shows that postoperative pain does not change with the chosen approach, but always maintains very low values, typical of minimally invasive surgery. The pain score is significantly higher in patients undergoing thoracic surgery, either robotic or thoracoscopic, compared to those undergoing gastrointestinal surgery (P corrected according to Bonferroni: 0.0006) and those undergoing urological intervention (P corrected according to Bonferroni: 0.04). In conclusion, no significant change in the intensity of postoperative pain between the two groups was found, while it is seen that the pain in patients undergoing thoracic interventions (robotic/thoracoscopic) is more intense than that reported for other types of interventions.

Abstract
BACKGROUND Although shown to be safe in infancy, robotic-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction obstruction (UPJO) is most commonly performed in older children and adolescents. OBJECTIVE This study examined a contemporary RALP experience at a single tertiary pediatric center and compared outcomes in infants aged ≤1 year with an older cohort. METHODS AND DESIGN All RALP procedures were entered into an Institutional Review Board-approved data registry from 2012 to 2016. Patients were retrospectively grouped according to age. The primary outcome was success rate. Secondary outcomes included complications and length of hospital stay. Failure was defined as the need for secondary surgical intervention for UPJO or worsening urinary tract dilation on imaging. Statistical analysis was performed using SPSS version 20. Mann-Whitney U testing was used for comparison. RESULTS A total of 138 patients underwent RALP during 2012-2016, with a median age of 6 years (IQR 1, 13.25) and a male:female ratio of approximately 2:1. Of these, 34 (24.6%) were aged ≤1 year. Of all patients, 60 (43.5%) presented with a history of prenatal hydronephrosis, and 32% had a crossing vessel causing obstruction. An indwelling stent was placed in antegrade fashion in 71% of cases, and 18% had a percutaneously placed externalized stent. There were six (4%) failures requiring reoperation. Multivariate and comparative analysis demonstrated that the infant cohort utilized less morphine equivalents and more often had a percutaneous stent placed compared to the older cohort. Of the complications that occurred, 60% were minor (Clavien grades 1 and 2) and 40% were Clavien grade 3 in the infant cohort, and 70.1% and 29.9% in the older cohort, respectively. No studied criteria predicted failure in either cohort. CONCLUSION This study presented one of the largest contemporary series of consecutive pediatric RALPs, and showed an overall success rate of 96%. There were no significant differences in length of hospital stay, and complications or failure rates in infants compared to older children. This study substantiated the ongoing trend towards the adaptation of robotic-assisted surgery for the entire pediatric patient population.

Abstract
PURPOSE Robot-assisted laparoscopic pyeloplasty (RALP) and laparoscopic pyeloplasty (LP) are both minimally invasive surgical options to correct ureteropelvic junction obstruction in children. There are limited data reporting surgeons' experience of switching from LP to RALP and comparing the outcomes of the two procedures. METHODS We conducted a retrospective study on 63 consecutive children who underwent either LP or RALP by the same surgeon in a tertiary center from January 2008 to November 2016. LP had been the standard practice until January 2014 when it was replaced by RALP in short transition. RESULTS Thirty-seven LP and 26 RALP were successfully performed in children aged 2 months to 16 years. There was no difference between the two groups in age, body weight, laterality, clinical presentations, preoperative imagings, primary/reoperative repairs. The overall success rates were 34/37 (91.9%) and 25/26 (96.2%) for LP and RALP, respectively (P > .05). RALP was associated with shorter length of stay (3.1 days versus 4.0 days; P = .03). Surgeon-in-training participation was greater in RALP group (P < .001). There was no difference in operative time, complication rates, and analgesic requirement between the two groups. CONCLUSIONS Surgeons proficient in LP can adapt quickly to RALP, achieving comparable outcomes. Robotic technology may facilitate training on minimally invasive pyeloplasty.

Abstract
INTRODUCTION Over the last decade the literature, including a multidisciplinary consensus statement, has supported a paradigm shift in management of urinary tract dilation, yet the impact on practice patterns has not been well documented. OBJECTIVE This study aims to elucidate specific practice patterns for treatment of prenatal unilateral urinary tract dilation and to assess surgical intervention patterns for ureteropelvic junction obstruction. STUDY DESIGN An online survey was distributed to 234 pediatric urologists through the Society of Pediatric Urology. The survey was composed of five clinical case scenarios addressing evaluation and management of unilateral urinary tract dilation. RESULTS The response rate was 71% (n = 168). Circumcision status, gender, and grade were significant factors in recommending prophylactic antibiotics for newborn urinary tract dilation. Prophylactic antibiotic use in the uncircumcised male and female was twice that of a circumcised male for grade 3 (Table). This difference was minimized for grade 4. Use of VCUG was high for circumcised males with grade 3 or 4 (Table). The choice of minimally invasive surgery for ureteropelvic junction repair increased with age from 19% for a 5-month-old, 49% for a 2-year-old, and 85% for a 10-year-old. Notably, 44% of respondents would observe a 10-year-old with intermittent obstruction. Retrograde pyelography was recommended in conjunction with repair in 65% of respondents. Antegrade stent placement was the most common choice (38-47%) for urinary diversion after pyeloplasty. Regarding postoperative imaging, only 5% opted for routine renal scan whereas most would perform renal ultrasound alone. DISCUSSION Practice patterns seen for use of prophylactic antibiotics are in agreement with the literature, which promotes selective use in those at highest risk for urinary tract infections. Interestingly, use of aggressive screening was not concordant with this literature. Several studies have indicated an increased usage of robotic pyeloplasty; however, results indicate that minimally invasive surgery is not preferred in those younger than 6 months. Study limitations include use of clinical case scenarios as opposed to actual clinical practice. CONCLUSION Practice patterns for prophylactic antibiotic use for neonatal urinary tract dilation are dependent on gender, circumcision status, and grade. The use of minimally invasive surgery for ureteropelvic junction repair increased with patient age, with 50% preferring this modality at 2 years.

Abstract
Ureteropelvic junction obstruction is a common condition encountered by the pediatric urologist, and treated with pyeloplasty when indicated. Recent technological advancements and a shift across all surgical fields to embrace minimally invasive surgery have led to increased utilization of minimally invasive pyeloplasty. Conventional laparoscopy is a reasonable choice, but its use is limited by the technical challenges of precise suturing in a confined space and the associated considerable learning curve. Robotic technology has simplified the minimally invasive approach to pyeloplasty, offering enhanced visualization and improved dexterity with a fairly short learning curve. As utilization of robotic pyeloplasty continues to increase, we sought to critically assess the literature on this approach. We begin with a review of the technical aspects of robot-assisted laparoscopic pyeloplasty including tips for surgical proficiency and patient safety. Outcomes and complications from the contemporary literature are reviewed, as well as special considerations in the pediatric population including infant pyeloplasty, cost concerns, training, and postoperative diversion/drainage.

Abstract
The inaugural robot-assisted urological procedure in a child was performed in 2002. This study aims to catalogue the impact of this technology by utilizing bibliographic data as a surrogate measure for global diffusion activity and to appraise the quality of evidence in this field. A systematic literature search was performed to retrieve all reported cases of paediatric robot-assisted urological surgery published between 2003 and 2016. The status of scientific community acceptance was determined using a newly developed analysis model named progressive scholarly acceptance. A total of 151 publications were identified that reported 3688 procedures in 3372 patients. The most reported procedures were pyeloplasty (n = 1923) and ureteral reimplantation (n = 1120). There were 16 countries and 48 institutions represented in the literature. On average, the total case volume reported in the literature more than doubled each year (mean value increase 236.6% per annum). The level of evidence for original studies remains limited to case reports, case series and retrospective comparative studies. Progressive Scholarly Acceptance charts indicate that robot-assisted techniques for pyeloplasty or ureteral reimplantation are yet to be accepted by the scientific community. Global adoption trends for robotic surgery in paediatric urology have been progressive but remain low volume. Pyeloplasty and ureteral reimplantation are dominant applications. Robot-assisted techniques for these procedures are not supported by high quality evidence at present. Next-generation robots are forecast to be smaller, cheaper, more advanced and customized for paediatric patients. Ongoing critical evaluation must occur simultaneously with expected technology evolution.

Abstract
PURPOSE The purpose of this study is twofold: first, to describe the non-narcotic pathway (NNP) for the management of postoperative pain after robotic pyeloplasty (RP); second, to compare perioperative outcomes for children undergoing RP whose postoperative pain was managed with and without the NNP. PATIENTS AND METHODS A retrospective review was performed on 96 consecutive patients from October 2011 to December 2015 who underwent RP by three primary surgeons at a single pediatric institution. Children managed with an NNP received alternating doses of scheduled intravenous acetaminophen and ketorolac every 3 hours throughout the postoperative course. Perioperative outcomes were compared after grouping patients according to the type of postoperative pain management pathway. Continuous variables were compared using the Mann-Whitney U test, and categorical variables were compared using the two-tailed chi-squared test. RESULTS A total of 49 (51.0%) patients were managed with the NNP, and 47 (49.0%) patients were managed without the NNP. A larger proportion of patients in the NNP did not receive postoperative narcotic medications (71.4% vs 25.5%; p < 0.001). Patients in the NNP were administered less narcotics (median 0.000 mg vs 0.041 mg morphine equivalents/kg/day; p < 0.001) and had a shorter length of stay (median 1.0 day vs 2.0 days; p < 0.001). There was no significant difference in the proportion of patients with postoperative complications (p = 0.958) or surgical success (p = 0.958). CONCLUSIONS An NNP following pediatric RP is a viable and effective analgesic regimen that is associated with less narcotic use. It may also facilitate a shorter hospital stay. The majority of patients managed with this pathway had adequate pain control without being subject to the potential adverse effects of narcotic medications.

Abstract
The laparoscopic approach to the pyeloplasty procedure has proven to be safe and effective in the pediatric population. Multiple studies have revealed outcomes comparable to the open approach. However, a major drawback to laparoscopy is the technical challenge of precise suturing in the small working space in children. The advantages of robotic surgery when compared to conventional laparoscopy have been well established and include motion scaling, enhanced magnification, 3-dimensional stereoscopic vision, and improved instrument dexterity. As a result, surgeons with limited laparoscopic experience are able to more readily acquire robotic surgical skills. Limitations of the robotic platform include its high costs for acquisition and maintenance, as well as the need for additional robotic surgical training. In this article, we review the current status of the robot-assisted laparoscopic pyeloplasty, including a brief history, comparative outcomes, cost considerations, and training.

Abstract
BACKGROUND A few studies have compared robotic-assisted laparoscopic pyeloplasty (RALP) with open pyeloplasty (OP) in children, but no previous study includes a long-term follow-up of renal function and hydronephrosis in combination with a thorough prospective follow-up of the RALP patients of at least 2 years. OBJECTIVE To analyze perioperative results and long-term outcome of children with obstruction of the ureteropelvic junction, operated on with RALP compared to OP. PATIENTS AND METHODS Children ≤15 years operated on with RALP or OP from 2000 through 2013 were reviewed. Patient demographics, perioperative data, postoperative complications, and long-term outcome were evaluated. The outcome was based on pre- and postoperative examination of renal function, hydronephrosis and flank pain. RESULTS 129 pyeloplasties (84 OP, 39 RALP, 6 reoperations) on 123 patients were included. RALP had significantly longer operative time and shorter postoperative hospital stay, compared to OP. No difference was found in postoperative need of morphine or complication rates. Mean follow-up for RALP with ultrasound was 29 and 25 months with renal scan, compared to 34 and 28 months, respectively, for OP. The success rate for flank pain was 96 and 94 %, for hydronephrosis 93 and 95 %, and renal function 94 and 92 %, for RALP and OP, respectively. CONCLUSIONS RALP is a safe method, with advantages compared to OP, and with the same success rate. This study supports the use of RALP in children.

Abstract
PURPOSE The aim of this study is to analyze results of retrograde endopyelotomy with cutting balloon for treatment of ureteropelvic junction obstruction (UPJO) in infants. METHODS We routinely treat patients with UPJO under 18 months of age with retrograde high-pressure balloon dilatation of the pelviureteric junction (PUJ). During the procedure, in these cases where narrowing at the PUJ persists, endopyelotomy with cutting balloon is performed. Endopyelotomy is performed over guidewire with 5-mm Cutting Balloon™ under fluoroscopic control. Double-J stents is left in situ for 4 weeks. We retrospectively analyzed the postoperative, clinical, and radiological outcome infants treated with cutting balloon endopyelotomy between 2007 and 2015. RESULTS Sixteen patients required cutting balloon endopyelotomy to achieve complete resolution of narrowing of the waist observed during high-pressure balloon dilatation of the PUJ. Mean operative time was 35 ± 21 min (mean ± SD) and hospital stay was <24 h in all patients. Complete resolution of the narrowing at the PUJ under fluoroscopy was achieved in all cases, with no perioperative complications. One patient presented with urinary tract infection, postoperatively (Clavien grade II). Preoperatively, all cases had grade IV SFU hydronephrosis with parenchymal thinning. During follow-up, resolution of the hydronephrosis was observed in 11 patients (grade I SFU). In four infants, there was an improvement of the hydronephrosis (grade II SFU) and the renogram curve. In one case, an open pyeloplasty was required due to persistent hydronephrosis and obstructive curve. CONCLUSION We believe that endopyelotomy with cutting balloon could be a valid and safe option in minimally invasive management of UPJO in infants.

Abstract
OBJECTIVE This manuscript is mainly to systemically review the published reports that compared the efficacy and safety of robotic-assisted (RP) versus open pyeloplasty (OP) in children with ureteropelvic junction obstruction (UPJO). METHODS We did a systemic search in the PubMed(®) for all randomized controlled trials or comparative studies that compared the surgical results of robotic versus open pyeloplasty in children with UPJO. Two of the authors (Hsu and Chang) independently did the literature search, quality assessment, and data extraction. The obtained data were analyzed with Cochrane Collaboration Review Manager (RevMan(®), version 5.3). The end points of the analysis and review included age, operative time, hospital stay, costs, complications, and success rate. RESULTS In total, seven comparative trials and three studies using national database met the criteria that comprised 20,691 (RP:OP = 1956:18,735) patients in the meta-analysis. Most studies reported median value of patient age, operative time, and hospital stay. Only a small proportion of studies could be included for meta-analysis. The enrolled trials revealed that RP was more frequently performed in older children, required longer operative time, and shorter hospital stay. The postoperative success rate was comparable (RR = 0.99, 95 CI 0.94-1.04). Comparing with OP, there was a significant higher complication rate (RR = 1.29, 95 CI 1.10-1.51) and higher costs in the RP group. CONCLUSION Robotic-assisted pyeloplasty may be a promising alternative minimal invasive surgery for UPJO in children if the higher complication rates and higher costs in the RP can be overcome in the near future.

Robot-assisted laparoscopic pyeloplasty: Multi-institutional experience in infants. J Pediatr Urol 2015; 11:139.e1-5.

Abstract
INTRODUCTION Robot-assisted laparoscopic pyeloplasty (RALP) has been gaining acceptance among pediatric urologists. Over 300 have been described in the literature, but few studies have evaluated the role of RALP in infants alone. OBJECTIVE We sought to examine the operative experience and outcomes of RALP in a cohort of infants treated at multiple institutions across the United States. Our primary aim was to describe the safety and efficacy of RALP within this cohort. We recognize the challenges of performing minimally invasive surgery in small patients. In our paper, we address some technical considerations for the infant population. STUDY DESIGN This multi-centered observational study collected data on subjects one year of age or less who underwent RALP between April 2006 and July 2012 at five institutions. The primary outcome was resolution of hydronephrosis, and secondary outcomes included surgical time and complications. RESULTS A total of 60 patients (62 procedures) underwent RALP by six surgeons during the study period. All surgeons had > 5 years of experience beyond fellowship training. Mean surgical age was 7.3 months (SD ± 1.7 mo), 56 patients (95%) were diagnosed prenatally, and 59 patients (95%) had follow up imaging. Of these patients, 91% showed resolution or improvement of hydronephrosis. Two patients had recurrent obstruction and required additional surgery. Mean surgical time was 3 hours 52 minutes (SD ± 43 minutes). Seven (11%) patients reported intra-operative or immediate post-operative complications. DISCUSSION This series found a 91% success rate for reduction or resolution of hydronephrosis, and an 11% complication rate. This is equivalent to modern series comparing open pyeloplasty to pure laparoscopic and robotic-assisted laparoscopic pyeloplasty, which report success rates ranging from 70-96%, and complication rates ranging from 0-24% for open pyeloplasty. We lacked a standardized technique amongst institutions. This was not surprising since there are not established technical benchmarks for this surgery. However, we specified multiple technical considerations for this unique patient population. CONCLUSION The advantages of using robot-assistance to perform pyeloplasty in infants remain to be defined. This study cannot make that assessment due to small sample size. Nonetheless, this cohort is the largest robotic pyeloplasty series in infants to date. Seeing an excellent success rate and a low complication rate in this infant cohort is encouraging.

Perioperative effects of caudal and transversus abdominis plane (TAP) blocks for children undergoing urologic robot-assisted laparoscopic surgery. J Pediatr Urol 2015; 11:121.e1-7.

Abstract
INTRODUCTION Regional anesthesia is often used in combination with general anesthesia for pediatric surgery, however, it is unknown if adjunctive regional blocks are beneficial to children undergoing urologic laparoscopic or robot-assisted laparoscopic (RAL) procedures. OBJECTIVE To compare perioperative outcomes in children with adjunctive caudal blocks, transversus abdominis plane (TAP) blocks, or no regional anesthesia for common RAL surgical procedures in pediatric urology. STUDY DESIGN Inclusion in this retrospective study was limited to children who underwent RAL renal or ureteral/bladder procedures and received a standardized regimen of scheduled intravenous ketorolac and oral acetaminophen for acute postoperative pain control, with opioids as needed (PRN). Perioperative outcomes were compared between patients with an adjunctive caudal block (n = 25), bilateral TAP blocks (n = 44), or no regional anesthesia (n = 51). RESULTS Children with a preoperative caudal block received less intraoperative opioids than children with TAP blocks or no regional anesthesia (p < 0.001). This difference was observed both for renal procedures (p < 0.01) and ureteral/bladder procedures (p = 0.01). Patients with caudal blocks were also the least likely to require postoperative antiemetics (p = 0.03). There were no significant differences between groups in postoperative opioid use, maximum pain scores within 6 and 24 hours postoperatively, or length of hospital stay (LOS). No complications attributable to regional blocks were identified by chart review. DISCUSSION Use of adjunctive caudal blocks for pediatric RAL renal or ureteral/bladder surgical procedures may reduce need for alternate analgesic and/or anesthetic agents intraoperatively, as well as decrease postoperative nausea and vomiting. These findings may be related, since nausea and vomiting are common side effects of opioids and inhalational anesthetics. Consideration of the potential impact of caudal blocks on general anesthetic requirements is timely in light of concerns regarding the risk of anesthetic neurotoxicity in young patients. There was no evidence of improved postoperative pain control or shorter LOS for children who received regional anesthesia. It is unknown if regional blocks would have a greater impact in the absence of scheduled pain medications, which all patients in our study received. Limitations of this study include its retrospective nature and moderate sample size. Future randomized controlled trials are necessary to provide a more definitive understanding of regional anesthesia's role in minimizing pediatric surgical and anesthetic morbidity. CONCLUSION Administration of caudal blocks should be considered for children of suitable age undergoing RAL surgery involving either the upper or lower urinary tract.

Abstract
Robotic pyeloplasty is now commonly performed for children with ureteropelvic junction obstruction. Because surgical robotics is a tool that facilitates pyeloplasty and other reconstructive urologic operations, the indications for robotic-assisted laparoscopic pyeloplasty are the same as those for an open pyeloplasty but offer distinct advantages with respect to visualization, range of motion, and ease of laparoscopic suturing. In this review, the authors discuss the operative approach for robotic pyeloplasty in children and the extensions of the basic techniques to challenging clinical scenarios.
