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
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.

The efficacy of robotic-assisted laparoscopic pyeloplasty for pediatric ureteropelvic junction obstruction: a systematic review and meta-analysis. Pediatr Surg Int 2023; 39:265.

Abstract
To evaluate the safety and effectiveness of robotic-assisted laparoscopic pyeloplasty (RALP) for treating pediatric ureteropelvic junction obstruction through an extensive comparison of RALP, open pyeloplasty (OP) and laparoscopic pyeloplasty (LP). We conducted a comprehensive search of the following databases: PubMed, Excerpta Medica Database, Cochrane Library, Web of Science database, China National Knowledge Infrastructure, WanFang Data, and China Biology Medical Disc. Baseline data were compared, the sources of heterogeneity were assessed, and publication biases were detected. This study was registered with PROSPERO (CRD42023415667). 26 studies with 6074 cases performing pyeloplasty were included, and the overall data are comparable. Our analysis showed no significant difference in success rate and postoperative complications between RALP and OP, and RALP is associated with a shorter length of stay (LOS) (MD - 1.00 95%CI - 1.45 to - 0.55, p < 0.0001). In addition, compared to LP, RALP was associated with a shorter anastomosis time (MD - 18.35 95%CI - 29.88 to - 6.82, p = 0.002) and fewer postoperative analgesics (MD - 0.09 95% CI - 0.18 to - 0.01, p = 0.03); however, RALP has a longer operative time (OT) (MD 52.39, 95% CI 39.75-65.03, p < 0.00001) and higher cost. The heterogeneity of OT may be influenced by factors, such as age and region, while the heterogeneity of LOS primarily stems from regional differences. No significant publication bias was detected. Our meta-analysis shows that RALP can be an alternative to OP and LP with a high success rate, minimal postoperative complications, and shorter LOS. In addition, RALP contributes to reduce anastomosis time and postoperative analgesic drugs. However, further well-designed, large-scale, randomized controlled trials with additional parameters are needed to conduct a more comprehensive analysis of heterogeneity.

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
PURPOSE There is a paucity of data regarding the comparison of robotic and laparoscopic hepaticojejunostomy (HJ) for the treatment of paediatric choledochal cysts. Thus, our primary objective was a comparison of early complications namely post-operative bleeding, anastomotic leak, intestinal obstruction and the need for reoperation in both techniques. Our secondary objectives included a comparison of the mean time for surgery and HJ, conversion of procedure to open, intraoperative blood loss, late complications like cholangitis, stricture and post-operative outcomes like time to start oral feeds and length of post-operative stay. METHODS A retrospective data analysis of all children who underwent laparoscopic and robotic choledochal cyst excision with Roux-en-Y HJ from 2008 to 2021 was performed. RESULTS Ninety patients were classified into Group R (robotic HJ), n = 20 and Group L (laparoscopic HJ), n = 70. Post-operative complications were comparable amongst groups R and L (2 vs 6; p = 1 and 1 vs 2, p = 0.53, respectively). Intraoperative blood loss was significantly less in group R (54.8 ± 13.5 ml vs 64.1 ± 17.3 ml; p = 0.0280). The mean time to complete HJ was significantly less in group R (58 ± 12 min vs 71 ± 11 min; p < 0.001) while the mean time to complete surgery was significantly more in Group R (284 ± 14 min vs 195 ± 18 min; p < 0.001). CONCLUSION Our preliminary research report suggests overall comparable early complications in both groups.

Abstract
In contrast to many other countries, robot-assisted (RA) pediatric surgery is not yet very common in Germany. Although the first pediatric RA intervention was published in 2001, RA pediatric surgery is still perceived as a “new technology”. As a consequence, little is known about parents’ perception of this operation method. In this study, we analyzed parents‘ intention to let their child undergo RA and laparoscopic (LA) surgery. Two subsamples (online and at the University Medical Center Goettingen) received a questionnaire addressing attitude towards RA and LA pediatric surgery with the help of a case example. Results showed that parents had a higher intention to consent to LA surgery. Perceiving more benefits, assuming a positive attitude of the social environment, and feeling less anxiety increased intention. A mediation analysis indicated that the type of surgery affected intentions through assumed attitude of the social environment. Exploratory analyses showed that the perception of risks and anxiety reduced intention for only RA surgery. These findings should be considered in preoperational discussions with parents. Anxiety and perceived risks should especially be addressed in order to encounter hesitancy.

World J Urol 2022; 40:1049-1056.

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.

Front Pediatr 2022; 10:1052440. [PMID: 36507128 PMCID: PMC9727311 DOI: 10.3389/fped.2022.1052440] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Accepted: 10/31/2022] [Indexed: 11/24/2022] Open
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.

[PMID: 34635439 DOI: 10.1016/j.jpurol.2021.09.023] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 09/06/2021] [Accepted: 09/23/2021] [Indexed: 11/24/2022]
Abstract
INTRODUCTION Robot-assisted laparoscopic (RAL) urologic surgery is widely used in pediatric patients, though less commonly in infants. There are small series demonstrating safety and efficacy in infants, however, stratification by infant size has rarely been reported. Whether a cut-off weight, below which RAL surgery is not technically feasible, safe, or efficacious has not be determined. OBJECTIVE To assess safety and efficacy of RAL urologic procedures in infants <1 year of age, weighing ≤10 kg. STUDY DESIGN A single-institution retrospective cohort study of patients <1 year of age, and ≤10 kg undergoing RAL pyeloplasty (RALP) or RAL ipsilateral ureteroureterostomy (RALUU) between January 2011 and September 2020 was performed. Demographic, operative, and post-operative data were extracted from the medical record. Patients were stratified by post-hoc weight quartiles. Outcomes, including operative time, total OR time, estimated blood loss (EBL), post-operative length of stay (LOS), post-operative radiographic improvement, and 30-day complications were assessed by weight quartile for each procedure. The Kruskal-Wallis rank test was used to assess differences in continuous outcomes between weight quartiles and Pearson's Chi-squared test was used for categorical outcomes. RESULTS Of 696 RAL urologic surgeries performed, 101 met eligibility criteria. Median (IQR) age of patients was 7.2 (6.0-9.2) months with median weight of 8.0 (7.2-8.9) kg. The lowest weight was 5.5 kg. Procedures performed included 79 RALPs (78.2%), 22 RALUUs (21.8%). We identified 97 patients (94%) with post-operative imaging, with radiographic improvement in 92%. When stratified by weight quartile, there was no difference between groups in median operative time, total OR time, LOS, EBL, or post-operative radiographic improvement for both RALP and RALUU. Post-operative complications were assessed based on Clavien-Dindo classification with the majority of complications (9/12, 75%) in the >50th percentile weight groups. DISCUSSION To our knowledge, this is the largest published series of infant RAL urologic procedures, with similar rates of radiographic improvement and post-operative complications to prior published series. There are few prior series of RALP and RALUU in infants ≤10 kg, and we show comparable outcomes regardless of patient weight. Our study is limited by the inherent biases of retrospective studies. CONCLUSION RAL urologic surgery is technically feasible, safe, and efficacious in infants ≤10 kg, without worse outcomes as weight decrease. A cut-off weight, below which RAL surgery should not be performed has yet to be identified.

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: Comparative outcome studies investigating internal Double-J (DJ) and externalized stents have primarily been performed for open and laparoscopic pyeloplasty, with a paucity of literature surrounding outcomes in robot-assisted laparoscopic pyeloplasty (RALP). Furthermore, outcomes of a modified external stent inserted into the renal pelvis, termed cutaneous pyeloureteral (CPU) stent, remain unexamined. This study investigates outcomes of DJ and CPU stents as methods of trans-anastomotic drainage. Materials and Methods: A retrospective analysis identified pediatric patients who underwent RALP between December 2007 and January 2020 at a single tertiary center, where CPU stents were introduced in June 2012. Operative success was defined as improved or stable hydronephrosis without subsequent redo pyeloplasty. Secondary outcomes included stent reinsertion, anesthesia requirements, opioid administration, urinary tract infection (UTI), and bladder spasms. Results: A total of 103 pediatric RALP procedures were analyzed (DJ = 70, CPU = 33). Operative success (DJ = 95.7%, CPU = 100%, p = 0.55), Society for Fetal Urology (SFU) grade improvement, and length of stay were comparable. Accidental stent expulsion was only seen with CPU stents (9%; p = 0.03). Intracorporeal stent migration also occurred more frequently in CPU stents (DJ = 3%, CPU = 15%, p = 0.03). Stent reinsertion, when needed, used a DJ stent with rates of 4% and 9% for DJ and CPU stents, respectively (p = 0.38). DJ stents were removed at a later postoperative day (DJ = 45.2 ± 25.0, CPU = 8.3 ± 4.2; p < 0.001) with increased general anesthesia (DJ = 99%, CPU = 3%; p < 0.001) and intravenous (IV) opioid (DJ = 27%, CPU = 9%; p = 0.04) requirements. Finally, DJ stents had nonsignificant increased rates of UTI (DJ = 17%, CPU = 3%, p = 0.06) and bladder spasms necessitating postoperative medication (DJ = 26%, CPU = 9%, p = 0.07). Conclusions: DJ and CPU stents display equivalent success rates in pediatric RALP and similar stent reinsertion rates. Appreciable differences can inform stent selection, including higher general anesthesia requirements and IV opioid administration among DJ stents and a higher incidence of accidental stent expulsion among CPU stents. In addition, DJ stents were associated with nonsignificant increased rates of UTI and bladder spasm necessitating medication.

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
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 The transverse dorsal lumbotomy approach provides excellent exposure to the PUJ and causes minimal tissue damage. In this study, we assess the efficacy of dorsal lumbotomy in PUJ obstruction in children younger than 6 months. METHODS All children less than 6 months who were managed with the dorsal lumbotomy approach between 2009 and 2017 were reviewed prospectively. Data included: demographic data, pre/post-operative renal ultrasound scan with SFU grading and RDS, operative time, post-operative complications, and follow up results. RESULTS A total of 42 children with a mean age of 4.4 ± 1 months were included. On pre-operative RDS, all patients had an obstructive pattern and a SRF of 30.3 ± 9.3. The mean operative duration was 49 min and analgesia was minimal. Post-operative ultrasound at 6 months showed an improvement in hydronephrosis (p < 0.05) and a mean SRF of 39.3 ± 6.1 (p < 0.001). CONCLUSION Transverse dorsal lumbotomy approach is a safe and efficient alternative in patients less than 6 month.

Abstract
Objective: To present our primary experience of robotic-assisted laparoscopic pyeloplasty (RALP) for severe ureteropelvis junction obstruction (UPJO) infants under 3 months. Methods: We performed a retrospective study of 9 infants under 3 months who underwent RALP for severe UPJO between April 2017 and March 2019 in our center. The severe UPJO was defined as infants with severe hydronephrosis (Society of Fetal Urology grades III or IV, anteroposterior diameter >3 cm or split renal function <40% or T 1/2 >20 min) involving bilateral, solitary kidney, or contralateral renal hypoplasia UPJO at the same time. All clinical, perioperative, and postoperative information was collected. Results: There were four bilateral UPJO cases, two solitary kidney UPJO cases and three unilateral UPJO with contralateral renal hypoplasia cases included. One single surgeon performed RALP on all of the infants. The mean age of the infants was 1.62 ± 0.54 months. The mean operative time was 109.55 ± 10.47 min. The mean estimated blood loss was 19.29 ± 3.19 ml, and the mean length of hospital stay was 5.57 ± 0.73 days. According to the ultrasonography results, all patients had a significant recovery of renal function at 12 months after the operation. Conclusions: To maximize the protection of renal function, early RALP is a safe and feasible option for the treatment of severe UPJO in infants under 3 months.

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
Zusammenfassung
Hintergrund
Im Ausland stellt die roboterassistierte (RA-)Chirurgie und hier besonders die RA-Urologie in der Kinderchirurgie bereits eine wichtige Alternative zu konventionellen Eingriffen (offen, laparoskopisch, laparoskopisch-assistiert) dar. Für Deutschland wurden dazu erst wenige Untersuchungen publiziert.
Ziel der Arbeit (Fragestellung)
Im Sinne einer vergleichenden Serie sollten die ersten Fälle von RA-Nierenbecken-Plastiken der Kinderchirurgie der Universitätsmedizin Göttingen im Vergleich zu konventionell laparoskopisch-assistierten (LAA) vor dem Hintergrund der internationalen Literatur evaluiert werden.
Material und Methoden
Es werden retrospektiv die ersten 13 RA und 14, unter Berücksichtigung des Patientenalters ausgewählte, konventionell LAA Anderson-Hynes-Plastiken hinsichtlich Operationsdauer, Krankenhausverweildauer, Alter der Patienten, Komplikationen und Rezidiven untersucht. Laparoskopisch-assistierte Operationen werden laparoskopisch durchgeführt, lediglich die Anlage der Anastomose erfolgt über einen kleinen Flankenschnitt extrakorporal. Roboterassistierte Eingriffe verlaufen gänzlich laparoskopisch.
Ergebnisse
Für die Operationsdauer ergab sich kein signifikanter Unterschied (111,54 min vs. 117,64 min). Die Liegezeit fiel für RA-Eingriffe signifikant kürzer aus (5,85 Tage vs. 10,0 Tage). Die Altersverteilung ergab für die RA-Kohorte ein Mittel von 52,23 Monaten und für die LAA 30,29 Monate. Die Komplikationsrate betrug 15,38 % (Harntransportstörung, paralytischer Ileus und Dislokation des PDK sowie Omentumprolaps), die Rezidivrate 7,69 % für die RA Eingriffe. Für die LAA operierten Patienten und Patientinnen lagen die Werte bei 7,14 % (Dislokation der Doppel-J-Schiene nach kranial) und 14,28 %.
Diskussion
Die ersten RA-Nierenbecken-Plastiken unserer Klinik wiesen im internationalen Vergleich ähnliche Werte für Operationsdauer, Komplikations- sowie Rezidivrate auf. Es zeigten sich ein ähnliches Outcome für beide Operationsverfahren und keine signifikante Zeitersparnis durch Verwendung des OP-Roboters. Im Gegensatz dazu fiel die Krankenhausverweildauer nach RA-Eingriffen signifikant kürzer aus als nach LAA-Operationen. In der internationalen Literatur finden sich jedoch auch insgesamt kürzere Liegezeiten. Insgesamt stellen RA-Nierenbecken-Plastiken eine wertvolle Alterative zu LAA-Verfahren dar.

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.

Abstract
In the last decade, management of congenital UPJ obstruction has become progressively observational despite the lack of precise predictors of outcome. While it is clear that many children will have resolution of their hydronephrosis and healthy kidneys, it is equally clear that there are those in whom renal functional development is at risk. Surgical intervention for the young infant, under 6 months, has become relatively infrequent, yet can be necessary and poses unique challenges. This review will address the clinical evaluation of UPJO in the very young infant and approaches to determining in whom surgical intervention may be preferable, as well as surgical considerations for the small infant. There are some clinical scenarios where the need for intervention is readily apparent, such as the solitary kidney or in child with infection. In others, a careful evaluation and discussion with the family must be undertaken to identify the most appropriate course of care. Further, while minimally invasive pyeloplasty has become commonly performed, it is often withheld from those under 6 months. This review will discuss the key elements of that practice and offer a perspective of where minimally invasive pyeloplasty is of value in the small infant. The modern pediatric urologist must be aware of the various possible clinical situations that may be present with UPJO and feel comfortable in their decision-making and surgical care. Simply delaying an intervention until a child is bigger may not always be the best approach.

Abstract
PURPOSE OF REVIEW The goal of this article is to review the current role of robotic urologic surgery in the infant population across a spectrum of diseases and procedures. RECENT FINDINGS Robotic urological surgery has been performed in the infant population across a variety of conditions including ureteropelvic junction obstruction, vesicoureteral reflux, and duplicated and nonfunctional renal moieties. However, most of the durable evidence showing safety and success remains in the repair of the obstructed ureteropelvic junction. Included in this review are also strategies to address the limitations imposed by the unique physiology and anatomy of the infant. Robotic urologic surgery remains an alternative to other surgical approaches in the properly selected infant in the hands of experienced surgeons. As additional larger studies are performed, the utility of the robotic platform in this population will be clearer.

Abstract
Over the last 30 years, robotic surgery has evolved into the preferred surgical approach for many operative cases. Robotics has been associated with lower pain scales, shorter hospitalizations, and improved cosmesis (1, 2). However, its acceptance in pediatrics have been hampered by longer operative times, smaller working space, and limited fine surgical instruments. Many find these challenges even more pronounced when performing robotic surgery in infants (i.e., children <1 year old). Although the data in infants is less robust, many studies have shown benefits similar to the adult population. Specifically, multiple reports of robotic surgery in infants have shown lower postoperative analgesic use. Additionally, hospital stays are shorter, which may lead to quicker return to work for parents and guardians. Multiple reports have shown low complication rates of robotic surgery in infants. When complications have occurred, they are usually Clavien Grade 1 and 2, with occasional grade 3. Often the complications are not from the robotic technique, but are linked to other factors such as the ureteral stents (3, 4). Most importantly, the success rates of surgery are comparable to open surgery. This chapter will review indications for the most common urologic robotic surgeries performed in infants. Also, we will review reported results and complications of robotic surgery in children, with specific attention to the infant population. However, data focused only on infants is limited. Many studies have some infant patients, but their results are often mixed with all pediatric patients.

Abstract
PURPOSE RALP is rapidly becoming the new gold standard treatment for UPJO in children, who suffer from uretero-pelvic obstruction (UPJO). However, presently there is a lack of data regarding the outcomes of RALP in young infants and smaller children. This study aims to compare the outcomes of RALP in children weighing less than 10 kg and matched with an analogous cohort who underwent open pyeloplasty (OP). METHODS We prospectively compared patients who underwent RALP to a matched cohort of patients who underwent OP from our retrospectively acquired data registry. Comparative outcomes included: Demographics, success rate, complications, and length of hospital stay, postoperative pain score and failure rate. Failure was defined as the need for a secondary intervention for UPJO, or worsening hydronephrosis during follow-up. RESULTS A total of 15 patients with a median age of 8 months (range 5-11 months) and median weight 7 kg (range 5.6-9.8 kg) underwent RALP between 2016 and 2018, a matched cohort of 15 children who underwent OP similar in terms of age, weight, gender and affected side between 2014 and 2016. All children had prenatal diagnosis of hydronephrosis and underwent surgery utilizing combined general and regional (Caudal MO) anesthesia. Intrinsic obstruction was present in 13 of RALP group (86.7%) and in 14 in OP group (93.3%). Mean operative time was 67.8 + 13.4 min in RALP group, while 66.5 + 9.5 min in OP group. (p = 0.76) All but two patients in RALP group had stent inserted and required subsequent anesthesia for stent removal, while all OP children had a Salle Pyeloplasty stent inserted during the procedure and underwent removal in an ambulatory setting without the need for anesthesia. There were no failures recorded in the RALP group, while one patient in OP required a secondary intervention. Mean hospital stay was 1 day (1-2 days) for RALP and 2 days (2-3 days) for OP. There was no difference in FLACC Pain Scale in both groups. Clavien-Dindo grade I-II complications occurred in one patient from each group. Two patients from RALP underwent subsequent ureteral reimplantation due to accompanying uretero-vescical junction obstruction. CONCLUSIONS Our data suggest that RALP can be performed safely in pediatric patients weighing less than 10 kg. with similar outcomes when compared to patients undergoing an open procedure for the same pathology.

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.

Does the use of 5 mm instruments affect the outcomes of robot-assisted laparoscopic pyeloplasty in smaller working spaces? A comparative analysis of infants and older children. J Pediatr Urol 2018; 14:537.e1-537.e6. [PMID: 30007500 DOI: 10.1016/j.jpurol.2018.06.010] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2018] [Accepted: 06/24/2018] [Indexed: 12/12/2022]
Abstract
INTRODUCTION Pediatric robot-assisted laparoscopic (RAL) pyeloplasty has become a viable minimally invasive surgical option for ureteropelvic junction obstruction (UPJO) based on its efficacy and safety. However, RAL pyeloplasty in infants can be a challenging procedure because of the smaller working spaces. The use of the larger 8 mm instruments for these patients instead of the 5 mm instruments is common because of the shorter wrist lengths. OBJECTIVE We hypothesized that the use of 5 mm instruments for RAL pyeloplasty in infants with smaller working spaces will have comparable perioperative parameters and surgical outcomes in comparison with older children with larger working spaces. STUDY DESIGN We compared the perioperative parameters and surgical outcomes of RAL pyeloplasties performed by a single surgeon in infants and non-infant pediatric patients over a 2 year period. All of the procedures were performed using an 8.5 mm camera and 5 mm robotic instruments. Patient demographics, operative times, perioperative complications, hospital pain medication usage, hospital length of stay, and treatment success rates were compared between the two groups. RESULTS A total of 65 pediatric RAL pyeloplasties were included in the study (16 infants and 49 non-infants, Table). There were no significant differences in gender, laterality, proportion of re-do pyeloplasty, or preoperative hydronephrosis grade between the two groups. All procedures were performed without conversion to open surgery or significant perioperative complications. There were no differences in segmental operative times (total operative time, console time, port placement time, time for dissection to UPJO, and anastomosis time), hospital pain medication usage, and hospital length of stay between the two groups (p > 0.05 for all comparisons). The treatment success rates were 93.8% (15/16) and 100% (49/49), respectively (p = 0.08). DISCUSSION We present the first comparative study of infant and non-infant pediatric RAL pyeloplasty using 5 mm robotic instruments. An advantage of the current study is the use of a single surgeon's experience to compare RAL pyeloplasty outcomes in infants with those of older children, a group in which RAL pyeloplasty has already been shown to be efficacious and safe. Operative tips for infant RAL pyeloplasty are also provided. CONCLUSIONS RAL pyeloplasty is a safe and effective surgical modality even in infants, with comparable perioperative parameters and outcomes as those in older children. The use of 5 mm instruments in infants does not affect outcomes and offers the potential for improved cosmesis.

Abstract
Robot-assisted laparoscopic surgery (RALS) has been increasingly embraced in the fields of adult and pediatric urology, especially in North America and Europe. The advantages of a stable magnified 3-D view, tremor filtering, and motion scaling allow for precise intracorporeal exposure and suturing. Because most surgeries are performed as reconstructive rather than excision procedures, the robotic platform is particularly feasible for the field of pediatric urology. In this review, we summarize the recent viewpoints on RALS, such as pyeloplasty, ureteral reimplantation, bladder neck reconstruction, bladder neck sling, appendicovesicostomy, bladder diverticulectomy, and treatments for ureterocele or ectopic ureters, and we also critically summarize the current status of the literature. Based on our initial experience, RALS is technically feasible for pediatric patients and may be achieved with comparable surgical outcomes. RALS is also associated with reduced morbidity compared to open surgery to conventional laparoscopic surgery. This evolution will offer an alternative in the treatment pediatric patients, along with improved care and patient quality of life. Further large case series and randomized controlled trials that investigate the robotic platform's technological improvements will help to expand indications of RALS in the field of pediatric urology.

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 The adoption of robot-assisted laparoscopic (RAL) procedures in the field of urology has occurred rapidly, but is, to date, without pediatric-specific instrumentation. Surgical fog is a significant barrier to safe and efficient laparoscopy. This appears to be a significant challenge when adapting three-dimensional 8.5-mm scopes to use in pediatric RAL surgery. The objective of the present study was to compare matched controls from a prospectively collected database to procedures that were performed utilizing special equipment and a protocol to minimize surgical fog in pediatric RAL procedures. METHODS A prospectively collected database of all patients who underwent RAL pediatric urology procedures was used to compare: procedure, age, sex, American Society of Anesthesiologists score, weight, console time, number of times the camera was removed to clean the lens during a procedure, length of hospital stay, and morphine equivalents required in the postoperative period. A uniquely developed protocol was used, it consisted of humidified (95% relative humidity) and warmed CO2 gas (95 °F) insufflation via Insuflow® on a working trocar, with active smoke evacuation via PneuVIEW®XE on the opposite working trocar with a gas pass through of 3.5-5 l/min. The outcomes were compared with matched controls (Summary Fig). RESULTS The novel gas protocol was utilized in 13 procedures (five pyeloplasties, two revision pyeloplasties, three ureteroureterostomies (UU), three nephrectomies) and compared with 13 procedures (six pyeloplasties, one revision pyeloplasty, three UU, three nephrectomies) prior to the protocol development. There was no statistical difference in age (P = 0.78), sex (P = 0.11), ASA score (P = 1.00) or weight (P = 0.69). There were no open conversions, ≥Grade 2 Clavien complications, or readmissions within 30 days in either group. CONCLUSIONS This novel gas protocol yielded a statistically significant reduction in procedure time, by decreasing the number of times the camera was required to be pulled during the case by more than five occurrences, and saved approximately 35 min on average per case.

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
PURPOSE To compare the outcomes of open pyeloplasty (OP), laparoscopy-assisted extracorporeal (LEXP), and robotic-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction obstruction in pediatric patients. METHODS We retrospectively reviewed the age-matched cohort of 30 children who underwent OP, 30 who underwent LEXP, and 10 who underwent RALP at a single institution, from 1996 to 2014. Pre- and post-operative variables including success rate were compared among surgical groups. RESULTS The mean age of the patients was 120.2 months, the Society for Fetal Urology grade was 3.6, the anteroposterior diameter was 3.1 cm, and the renal relative function was 44.0%. The distribution of laterality, mean body mass index, and preoperative anteroposterior pelvic diameter on ultrasound did not differ among groups. The mean length of hospital stay was significantly shorter in the RALP group (3.2 days) than in the OP (6.6 days) and LEXP (5.8 days) groups (p<0.001). The duration of analgesics use was shorter in the RALP group (1.1 days) than in the other groups (p<0.001). During the mean follow-up period of 49.0, 20.1, and 16.6 months, the success rate was 96.7%, 89.7%, and 100% in the OP, LEXP, and RALP groups, respectively, although this difference was not statistically different (p = 0.499). In multivariate regression analysis, the presence of crossing vessels was the only factor that decreased the success rate (hazard ratio: 46.09, 95% confidence interval: 2.41-879.6, p = 0.011). CONCLUSIONS Patients who undergo RALP have a reduced hospital stay and lower use of pain medication; however, there is no difference in the success rates for OP, LP, and RALP surgeries. The presence of crossing vessels is a negative prognostic indicator for surgical outcome regardless of the surgical method.

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
INTRODUCTION Patient age and hospital volume have been shown to affect perioperative outcomes after pediatric pyeloplasty. However, there are few multicenter studies that focus on outcomes at teaching hospitals, where many of the operations are performed. OBJECTIVE The goal was to determine if surgical approach, age, case volume, or other factors influence perioperative outcomes in a large contemporary cohort. STUDY DESIGN Using the clinical database/resource manager (CDB/RM) of the University Health-System Consortium (UHC), children who underwent open, laparoscopic, or robotic pyeloplasty from 2011 to 2014 were identified at 102 academic institutions. Surgery type, age, race, gender, insurance type, geographic region, comorbidities, surgeon volume, and hospital volume were measured. Multivariable mixed-effects logistic regression analysis was used to analyze independent variables associated with complication rates, length of stay (LOS), readmission rates, and ICU admission. RESULTS A total of 2219 patients were identified. Complication rates were 2.1%, 2.2%, and 3% after open, laparoscopic, and robotic pyeloplasty, respectively. Approximately 12% of patients had underlying comorbidities. Comorbidities were associated with 3.1 times increased odds for complication (p = 0.001) and a 35% longer length of stay (p < 0.001). Age, gender, insurance type, and hospital volume had no effect on complication rates. A trend was seen towards a lower rate of complications with higher surgeon volume (p = 0.08). The mean LOS was 2.0 days in the open pyeloplasty group, 2.4 days in the laparoscopic group and 1.8 days in the robotic group. Patients who underwent robotic surgery had an estimated LOS 11% shorter than those after open surgery (p = 0.03) (Table). Patients aged 5 years and under who had robotic surgery had an estimated LOS 14% shorter than those after open surgery (p = 0.06). ICU admission and hospital readmission were not associated with any variables. DISCUSSION The study is limited by the accuracy of the data submitted by the hospitals and is subject to coding error. Complication rates remain low in all three approaches, validating their safety. Patients, including younger patients, had shorter lengths of stay after robotic surgery. The statistically significant differences between approaches were small so clinically there may not be a difference. CONCLUSIONS This large multicenter analysis demonstrates that patient comorbidity had the greatest impact upon complication rates and length of stay. Previous work showed that the benefits of laparoscopy were limited to older children. However, this large multicenter study suggests that these benefits now extend to young children with the application of robotics.

Abstract
BACKGROUND Robotic techniques are increasingly being used for reconstructive procedures in the pediatric population. OBJECTIVE The present study reported the functional and perioperative outcomes of a multi-institutional cohort of pediatric patients who underwent robotic-assisted laparoscopic Mitrofanoff appendicovesicostomy (RALMA). STUDY DESIGN Pediatric patients who underwent RALMA at five different centers were included. Positioning is shown (Summary Figure). Demographics were gathered, and intraoperative parameters included concomitant procedures, detrusor tunnel length, estimated blood loss (EBL) and operative time. Perioperative outcomes included length of hospital stay (LOS), morphine use and 30-day complications. Outcomes were reported in terms of stomal continence and surgical revisions. RESULTS Eighty-eight patients with a mean age of 10.4 ± 4.0 years were included in the analysis. Median follow-up was 29.5 months (IQR 11.8-45.0). Bladder augmentation was performed concomitantly in 15 (17%) patients, and bladder neck procedures in 34 (39%). Mean detrusor tunnel length was 3.9 ± 1.0 cm, EBL was 54 ± 70 ml, and operative time was 424 ± 120 min. Postoperatively, mean LOS was 5.2 ± 2.8 days. Patients who underwent concomitant augmentation had higher EBL and operative times (both P < 0.05). At 90 days, complications occurred in 26 patients (29.5%) with six Clavien grade ≥3 (6.8%). During follow-up, 11 (12.5%) patients required appendicovesicostomy revision. Regarding functional outcomes, 75 (85.2%) patients were initially continent. After additional procedures, 81 (92.0%) patients were continent at last follow-up. DISCUSSION Compared to previous open series, initial stomal continence rates with RALMA were acceptable, with a minority of patients requiring subsequent procedures to manage complications and achieve continence. CONCLUSION RALMA is safe and effective in a pediatric population with regard to perioperative complications and stomal continence.

Abstract
BACKGROUND Common causes of complications of laparoscopic pyeloplasty in children include anastomotic stricture, poor drainage due to high ureteropelvic anastomosis, and torsion of ureter. Herewith, we described our modified technique of paraumbilical three-port laparoscopic dismembered pyeloplasty (PTLDP) to minimize these complications. PATIENTS AND METHODS Data from 62 patients (age: 1-180 months, median: 12 months) with ureteropelvic junction obstruction (UPJO) who underwent pyeloplasty using our modified technique of PTLDP between February 2014 and September 2014 at our institution were reviewed. The key steps of our modified method involve identifying the lowest point of the renal pelvis and the lateral aspect of the ureter to guarantee a low pelviureteric and correct orientation anastomosis, and using a 4-0 silk for assistant suturing to avoid crushing of the anastomotic tissue. RESULTS All surgeries were successfully completed without conversion. Three patients required an accessory port for the anastomosis. All the patients achieved complete clinical or radiologic resolution after the operation. The mean operative time was 103.4 min, and mean estimated blood loss was 14.4 mL. Mean postoperative differential function of affected kidney was 43.0 ± 16.3 % (range 24-100 %), increased from 39.7 ± 18.0 % (range 18-100 %), preoperatively (p < 0.001). The success rate was 100 % at a mean follow-up of 18.3 ± 2.9 (range 13-25) months. CONCLUSIONS Our modified technique of PTLDP is safe and feasible and to allow high success rate for the treatment of pelviureteric junction obstruction in children.

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 Robotic technology is the newest tool in the armamentarium for minimally invasive surgery. Individual centers have reported on both the outcomes and complications associated with this technology, but the numbers in these studies remain small, and it has been difficult to extrapolate meaningful information. OBJECTIVES The intention was to evaluate a large cohort of pediatric robotic patients through a multi-center database in order to determine the frequency and types of complications associated with robotic surgery for pediatric reconstructive and ablative procedures in the United States. STUDY DESIGN After institutional review board approvals at the participating centers, data were retrospectively collected (2007-2011) by each institute and entered into a RedCap(®) database. Available demographic and complication data that were assigned Clavien grading scores were analyzed. RESULTS From a cohort of 858 patients (880 RAL procedures), Grade IIIa and Grade IIIb complications were seen in 41 (4.8%); and one patient (0.1%) had a grade IVa complication. Intraoperative visceral injuries secondary to robotic instrument exchange and traction injury were seen in four (0.5%) patients, with subsequent conversion to an open procedure. Grade I and II complications were seen in 59 (6.9%) and 70 (8.2%) patients, respectively; they were all managed conservatively. A total of 14 (1.6%) were converted to an open or pure laparoscopic procedure, of which, 12 (86%) were secondary to mechanical challenges. DISCUSSION It is believed that this study represents the largest and most comprehensive description of pediatric RAL urological complications to date. The results demonstrate a 4.7% rate of Clavien Grade IIIa and Grade IIIb complications in a total of 880 cases. While small numbers make it difficult to draw conclusions regarding the most complex reconstructive cases (bladder diverticulectomy, bladder neck revision, etc.), the data on the more commonly performed procedures, such as the RAL pyeloplasty and ureteral reimplantation, are robust and more likely represent the true complication rate for these procedures when performed by highly experienced robotic surgeons. CONCLUSION Pediatric robotic urologic procedures are technically feasible and safe. The overall 90-day complication rate is similar to reports of laparoscopic and open surgical procedures. COMPLICATIONS n (%) Life threatening (IVa): 1 (0.1%) Requiring radiologic and or surgical intervention (IIIa and IIIb): 41 (4.8%) Secondary to robotic system: 4 (0.5%) Mechanical failure leading to conversion: 14 (1.6%).

A comparative cost analysis of robotic-assisted surgery versus laparoscopic surgery and open surgery: the necessity of investing knowledgeably. Surg Endosc 2016; 30:5044-5051.

Abstract
BACKGROUND Robotic surgery has been proposed as a minimally invasive surgical technique with advantages for both surgeons and patients, but is associated with high costs (installation, use and maintenance). The Health Technology Assessment Unit of the Bambino Gesù Children's Hospital sought to investigate the economic sustainability of robotic surgery, having foreseen its impact on the hospital budget METHODS: Break-even and cost-minimization analyses were performed. A deterministic approach for sensitivity analysis was applied by varying the values of parameters between pre-defined ranges in different scenarios to see how the outcomes might differ. RESULTS The break-even analysis indicated that at least 349 annual interventions would need to be carried out to reach the break-even point. The cost-minimization analysis showed that robotic surgery was the most expensive procedure among the considered alternatives (in terms of the contribution margin). CONCLUSIONS Robotic surgery is a good clinical alternative to laparoscopic and open surgery (for many pediatric operations). However, the costs of robotic procedures are higher than the equivalent laparoscopic and open surgical interventions. Therefore, in the short run, these findings do not seem to support the decision to introduce a robotic system in our hospital.

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.

Abstract
BACKGROUND In pediatric urology, robot-assisted surgery has overcome several impediments of conventional laparoscopy. However, workspace has a major impact on surgical performance. The limited space in an infant can significantly impede the mobility of robotic instruments. There is currently no consensus on which infant can undergo robotic intervention and no parameters to help make this decision, especially for those surgeons at the start of their learning curve. OBJECTIVE We sought to evaluate our experience with infants to create an objective standard to determine which patients may be most suitable for robotic surgery. STUDY DESIGN We prospectively evaluated 45 infants (24 males, 21 females), aged 3-12 months old, who underwent a robotic intervention for either upper or lower urinary tract pathology. At the preoperative office visit the attending surgeon measured the distance between both anterior superior iliac spines (ASIS) as well as the puboxyphoid distance (PXD), regardless of whether the approach was for upper or lower tract disease. Patients' weights were also noted. During surgery, we recorded the number of robotic collisions as well as console time. All surgeries were performed utilizing the da Vinci Si Surgical System by a single surgeon. RESULTS There were no differences in ASIS, PXD, collisions or console time when stratified by gender, age or weight. When arranging by upper or lower tract approach, there was no difference in the number of collisions. There was a strong inverse relationship between both ASIS distance and PXD and the number of collisions. Additionally, there was a strong correlation between the number of collisions and console time (Fig. 1). Using a cutoff of 13 cm for the ASIS, there were significantly fewer collisions in the >13 cm group as compared to the ≤13 cm group. This was also true for the PXD using a cutoff of 15 cm: there were significantly fewer collisions in the >15 cm group as compared to the ≤15 cm group. DISCUSSION Safe proliferation of robotic technology in the infant population is, in part, dependent on careful patient selection. Our data demonstrated a reduction in instrument collisions and console time with increasing anterior superior iliac spine and puboxyphoid distances. Neither age nor weight was correlated with these measurements, the number of instrument collisions or console time. Limitations include that this is a single institution study with all infants being operated on by a single surgeon. Therefore, the findings of this study may not be generalizable to a less experienced surgeon. Yet, we believe that ASIS and PXD measurements can be used as a guide for the novice surgeon who is beginning to perform robotic-assisted surgery in infants. CONCLUSION We found that surgeon ability to perform robotic surgery in an infant is restricted by collisions when the infant has an ASIS measurement of 13 cm or less or a PXD of 15 cm or less. Objective assessment of anterior superior iliac spine and puboxyphoid distance can aid in selecting which infants can safely and efficiently undergo robotic intervention with a minimum of instrument collision, thereby minimizing operative time.

Robot-assisted laparoscopic pyeloplasty: Multi-institutional experience in infants. J Pediatr Urol 2015; 11:139.e1-5. [PMID: 26052000 DOI: 10.1016/j.jpurol.2014.11.025] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2014] [Accepted: 11/11/2014] [Indexed: 11/23/2022]
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.

Abstract
PURPOSE We evaluated the validity of robotic surgery (RS) for pediatric choledochal cyst (CC) in comparison to open surgery (OS). MATERIALS AND METHODS From January 2009 to April 2013, clinical data from 79 consecutive pediatric patients with CC, who underwent RS (n=36) or OS (n=43) performed by a single pediatric surgeon, were analyzed retrospectively. RESULTS In the RS group, the age of the patients was significantly older, compared to the OS group. Operation and anesthesia times were significantly longer in the RS group than the OS group. Fluid input rates to maintain the same urine output were significantly smaller in the RS group than the OS group. The American Society of Anesthesiologists (ASA) physical status, length of postoperative hospital stay, and the incidence of surgical complications did not differ significantly between the two groups. CONCLUSION Although early complications could not be avoided during the development of robotic surgical techniques, RS for pediatric CC showed results comparable to those for OS. We believe that RS may be a valid and alternative surgery for pediatric CC. After further development of robotic surgical systems and advancement of surgical techniques therewith, future prospective studies may reveal more positive results.
