Abstract
Context Minimally invasive management (laparoscopic/robot assisted) is currently the standard of care for managing pelvi ureteric junction obstruction (PUJO). Open techniques of management of PUJO are well described in literature. However, there appears to be relative lack of description of minimally invasive techniques in the literature. Objective This article is aimed at describing in detail, with images, the various techniques and modifications in laparoscopic or robot-assisted management of PUJO. Evidence Acquisition A review of literature on PubMed was performed and all articles which detailed any technique of minimally invasive pyeloplasty were included. Evidence Synthesis The various techniques of minimally invasive pyeloplasty as well as the authors' techniques are compiled and described in detail with intraoperative images. Conclusions Operative techniques of minimally invasive pyeloplasty are not well described in literature. We have attempted to present a comprehensive resource of different techniques of minimally invasive pyeloplasty and the clinical scenarios in which they may be appropriate. This should prove to be a useful reference to the practicing urologist. Patient Summary In this paper, we have compiled the various surgical techniques of treating obstruction at the PUJ of the kidney along with intraoperative photograph.

The application of artificial technology in pediatric pyeloplasty the efficacy analysis of robotic-assisted laparoscopic pyeloplasty in the treatment of ureteropelvic junction obstruction. Front Pediatr 2023; 11:1209359. [PMID: 37780043 PMCID: PMC10540863 DOI: 10.3389/fped.2023.1209359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 08/08/2023] [Indexed: 10/03/2023] Open
Abstract
Objective To investigate the clinical effect of the da Vinci robotic-assisted laparoscopic pyeloureteroplasty (RALP) in treating pediatric ureteropelvic junction obstruction (UPJO). Methods We retrospectively analyzed clinical data from 32 children with UPJO who suffered from RALP in our hospital from October 2020 to February 2023, compared with those treated with common laparoscopy at the same time. After the establishment of the robotic arm, a mesenteric approach was performed after entering the abdominal cavity to focus on the lesion site. The dilated renal pelvis was then cut and the stenotic ureter was removed; the anastomosis and the incision were sutured by layer. Results A total of 62 children (44 boys and 20 girls) with a median age of 14 months (ranging from 3 to 38 months) were included. All 62 cases had hydronephrosis caused by unilateral UPJO, and the surgery was successfully completed without conversion to open. All intraoperative blood losses amounted to less than 10 ml. In the RALP group, the average operative duration was 131.28 min (ranging from 108 to 180 min). The average catheter time was 3.66 days (ranging from 2 to 7 days). The average hematuria time was 3.84 days (ranging from 2 to 6 days). The average postoperative hospital stay was 7.8 days (ranging from 6 to 12 days). The average hospitalization costs were 59,048.31 yuan (ranging from 50,484 to 69,977 yuan). The double-J tube was removed 1 month after surgery. Only one patient suffered from complications, developing a urinary tract infection 4 weeks after surgery, and was cured with the administration of oral cefaclor anti-inflammatory drugs for 3 days. All patients were followed up for 2-28 months, with a median follow-up time of 12 months. The thickness of the renal cortex was increased after surgery [(1.95 ± 0.24) vs. (4.82 ± 0.50)] cm, and the isotope renograms revealed a definite recovery of the split renal function [(28.32 ± 1.95) vs. (37.01 ± 2.71)]%. Conclusion The robotic-assisted laparoscopic pyeloureteroplasty (RALP) in the treatment of children with upper ureteral obstruction has overall clinical efficiency. With technological advancements and an increased number of experienced surgeons, robotic surgery may become a new trend in surgery.

Laparoscopic versus robot-assisted pyeloplasty in infants and young children. Asian J Surg 2023; 46:868-873. [PMID: 36192267 DOI: 10.1016/j.asjsur.2022.09.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 03/22/2022] [Accepted: 09/11/2022] [Indexed: 02/08/2023] Open
Abstract
OBJECTIVE To compare the characteristics of conventional laparoscopic pyeloplasty (LP) and robotic-assisted laparoscopic pyeloplasty (RALP) in infants and young children with ureteropelvic junction obstruction (UPJO). METHODS We performed a retrospective study of patients (age: 0-36 months) who underwent dismembered pyeloplasty (Anderson-Hynes) with the fourth-generation RALP or traditional LP between April 2020 and December 2020. RESULTS A total of 33 patients with UPJO were enrolled: 12 underwent RALP (9 left side; 3 right side) and 21 underwent LP (18 left side; 3 right side). In the RALP group, the median patient age was 17 months (range: 5-36 months). In the LP group, the median patient age was 9 months (range: 2-36 months) (P = 0.182). The mean operation times were 120.25 ± 37.54 min (RALP) and 156.10 ± 51.11 min (LP) (P = 0.042), and the mean lengths of hospital stay were 6.42 ± 1.62 days (RALP) and 8.19 ± 2.25 days (LP) (P = 0.023). Removal of the drainage tube was performed after 3.08 ± 0.69 days (RALP) and after 4.76 ± 1.81 days (LP) (P = 0.001). The postoperative pain showed no significant difference. The mean hospitalization costs were 61464.75 ± 2800.53 yuan (RALP) and 22169.52 ± 3442.15 yuan (LP) (P < 0.001). The mean follow-up time was 10-18 months. Significant improvements in the anteroposterior diameter and parenchymal thickness were observed after surgery. Conversion to laparotomy was not performed. No short-term complications occurred during postoperative hospitalization and follow-up. CONCLUSION RALP has the advantages of less trauma and faster recovery. It can be safely and effectively performed in infants and young children, and its effectiveness is similar to that of traditional LP.

Abstract
INTRODUCTION Single-port robot-assisted laparoscopic surgery is a breakthrough in the field of minimally invasive surgery. However, it is currently only applicable to older children due to the limitation of operating space. Here, we report a case of single-port robot-assisted laparoscopic pyeloplasty (RALP) using the da Vinci Xi® surgical system in a 7-months infant. METHODS A 7-month-old infant with ureteropelvic junction obstruction (UPJO) underwent single-port RALP conducted using the da Vinci Xi® System. Retrospective perioperative, immediate postoperative outcomes and 9 months follow up were investigated. RESULTS Surgery progressed smoothly without additional operative port placement or open procedure. The total operative time was 160 min, including 90 min of console time. And estimated blood loss was 5 ml. No intraoperative and postoperative complications were found. Postoperative follow-up showed good efficacy, and the incision seemed to be traceless. CONCLUSION Single-port RALP using da Vinci Xi® System in infants is feasible and safe. It showed excellent efficacy in treating UPJO as shown in the short-term follow-up. Subsequent cohorts with more infant patients and long-term follow-up will be required to further validation.

Abstract
Background The aim of this study is to compare the results of laparoscopic pyeloplasty and robot-assisted laparoscopic pyeloplasty in patients with ureteropelvic junction obstruction. Methods Between March 2008 and May 2019, the patients who underwent retroperitoneal laparoscopic or robotic-assisted laparoscopic pyeloplasty in our institution were retrospectively reviewed. Results Thirteen patients underwent laparoscopically, and 12 patients underwent robotic surgery. The significant difference was found in median operative time between laparoscopic group (296 minutes) and robotic group (199 minutes) (P = 0.001). The median time for drain removal in laparoscopic group was longer than robotic group (3 vs. 2 days, respectively, P = 0.029). Conclusion Laparoscopic and robot-assisted laparoscopic pyeloplasty is safe and excellent success rates in patients with ureteropelvic junction obstruction. However, our experience study suggested that robotic surgery improves a total operative time, decreases drain removal time and less intraoperative blood loss than laparoscopic approach.

Abstract
OBJECTIVE This study aimed to compare the effects of various trocar placements in robot-assisted and laparoscopic pyeloplasty involving children diagnosed with obstruction of the ureteropelvic junction (OUPJ). METHODS We retrospectively collected the data on 74 patients under 14 years of age who had been diagnosed with OUPJ; these patients underwent either robot-assisted or laparoscopic pyeloplasty in our hospital between January 2015 and November 2021. There were four groups, as follows: •Laparoscopic multiport pyeloplasty (LMPY),•Laparoscopic single-port pyeloplasty (LSPY),•Robotic-assisted multiport pyeloplasty (RMPY),•Robotic-assisted single-port-plus-one pyeloplasty (RSPY).Patients' characteristics as well as their perioperative and follow-up data were collected and evaluated. RESULTS There was no significant difference in the data regarding patients' characteristics. These data included the grade of hydronephrosis according to the Society of Fetal Urology (SFU grade), anterior and posterior diameter of the renal pelvis and ureter (APDRPU), and the differential degree of renal function (DRF) at following time points: preoperative, postoperative, and comparison of preoperative and postoperative. There was no difference among these groups. During surgery, the time of trocar placement, urethroplasty time, and total operative time in the robotic groups (RMPY and RSPY) were longer than those in the laparoscopic groups (LMPY and LSPY). However, the ratio of the urethroplasty time and full operative time (UT/WT) in the robotic groups (RMPY and RSPY) was lower than that in the laparoscopic groups (LMPY and LSPY) (P = 0.0075). Also, the volume of blood loss was lower in the robotic groups (RMPY and RSPY) than that in the laparoscopic groups (LMPY and LSPY), although there was no statistical difference (P = 0.11). There were, however, significant differences in hospitalization days (P < 0.0001) and parents' cosmetic satisfaction scores (P < 0.001). There were no differences in fasting time, the length of time that a ureteral catheter remained in place, or the number of postoperative complications. CONCLUSION Our study shows that both robotic multiple-port and single-port-plus-one approaches are comparable, with laparoscopic multiple-port and single-port approaches equally effective in resolving OUPJ in children. Robotic and single-port-plus-one approaches may be associated with some advantages in hospitalization time and cosmetic outcomes; therefore, these approaches may be useful in urologic surgery that requires precise suturing, especially in pediatric patients.

Abstract
INTRODUCTION Robot-assisted laparoscopic pyeloplasty (RALP) is a safe and efficacious option for repair of UPJO. We hypothesize that redo-RALP is technically more difficult but has comparable outcomes to primary RALP. METHODS An IRB-approved single institutional registry was utilized to identify all patients undergoing primary or redo RALP from 2012 to 2019. Redo RALP consisted of pyeloplasty and ureterocalicostomy (RALUC). Peri-operative and post-operative details and outcomes were aggregated. Successful reconstruction was defined as resolution of symptoms, improved hydronephrosis and no need for additional procedures. RESULTS From 399 patients who underwent UPJO repair at our center, a total of 306 with a median age of 4.9 years at surgery and a median follow-up of 18.5 months were included: 276 primary and 30 redo (21 RALP and 9 RALUC). Redo group had significantly longer procedure time and length of stay compared to the primary group. However, no significant difference was noted in the post-operative complications, need for additional endoscopic procedures or redo reconstruction, and success between the two groups. Multivariate analysis showed that when controlled for age, gender, 30-days post-operative complication and anatomy of obstruction, redo as compared to primary reconstruction did not have a significant effect on success. DISCUSSION This study is the largest controlled cohort in the pediatric population comparing redo RALP with an established control group -primary RALP. This retrospective chart review possesses the biases innate to any retrospective study. The low number of re-operative cases as well as low rate of failure in redo RALP further complicates identification of statistically significant predictors of outcomes following redo RALP. CONCLUSION Redo RALP is an efficient and safe approach for reconstruction of recurrent UPJO, with low complication rate and high success rate, comparable to primary RALP.

Abstract
BACKGROUND Pelvi-ureteric junction obstruction (PUJO) is one of the common causes of obstructive uropathy dealt by urologists around the globe. The management of PUJO requires surgical intervention and pelvi-ureteral anastomosis is most time-consuming step in surgery and suturing plays a critical role for the good outcome of the surgery. OBJECTIVE To assess the outcomes of continuous or interrupted suturing in open pyeloplasties done for PUJ obstruction. MATERIALS AND METHODS This comparative study was conducted in the department of Urology in a tertiary care hospital of eastern India. A total of 60 patients with pelviureteric junction obstruction were included as per inclusion and exclusion criteria and divided into two groups depending upon whether continuous (Group A) or interrupted (Group B) suturing was done. Both groups were compared for mean operative time, mean suturing time, duration of post-operative drainage, mean drain output, post-operative hospital stay, postoperative GFR and improvement in GFR. RESULTS Out of 60 patients continuous and interrupted suturing was done in 30 patients in both arms. Out of 60 cases there were 46 (76.66%) males and 14 (23.33%) females with a M:F ratio of 1:0.30. The mean age in group A and group B was found to be 30.06 ± 8.28 and 27.63 ± 6.07, respectively. Mean operative time, mean suturing time, duration of post-operative drainage, mean drain output and postoperative hospital stay were found to be higher in interrupted suture group and the difference was found to be statistically highly significant (p < 0.0001). The complication rates and recurrence rates were found comparable in both the cases with no statistically significant difference (p > 0.05). CONCLUSION Continuous suturing technique for pyeloplasty is preferable as it is found to have a lower mean operative time, mean suturing time, duration of post-operative drainage, mean drain output and postoperative hospital stay.

Pyeloplasty is a safe and effective surgical approach for low functioning kidneys with ureteropelvic junction obstruction. J Pediatr Urol 2021; 17:233.e1-233.e7. [PMID: 33526368 DOI: 10.1016/j.jpurol.2020.12.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 12/10/2020] [Accepted: 12/17/2020] [Indexed: 02/05/2023]
Abstract
INTRODUCTION Indications for treatment of ureteropelvic junction obstruction (UPJO) include symptomatic obstruction, urinary tract infections, presence of an obstructive pattern on functional renal scan and/or worsening differential renal function (DRF). This paper aims to determine the relationship between preoperative DRF and surgical outcomes after pyeloplasty. We hypothesized that low preoperative DRF is not an independent predictor of pyeloplasty failure. METHODS A retrospective chart review was performed to identify all patients undergoing pyeloplasty for UPJO between 2008 and 2019. Patients were included only if they had at least one preoperative functional scan and a minimum of one renal ultrasound post-operatively. Patients were divided into three groups based on DRF for analysis: Group 1- 0-10%, Group 2 - >10-≤20%, Group 3 - >20%. Baseline, intraoperative and postoperative characteristics, including success and complications were compared. Additional sensitivity analyses were performed comparing patients with ≤20%, and >20% function, ≤30%, and >30% function as well as an analysis of patients undergoing only minimally invasive reconstruction. RESULTS Three hundred and sixty-four patients met inclusion criteria. We identified 8 patients in Group 1, 24 patients in Group 2 and 332 patients in Group 3. Mean procedure time was longest for the ≤10% function group (237.9 vs 206.4 vs 189.1; p = 0.01). We found no difference in 30-day post-operative complications, overall success rate or the need for additional procedures among the three groups. For patients in Group 1, we noted variation in the post-procedure DRF with a range of -2.8 to +47% change. In this group, none of patients with low DRF underwent nephrectomy. Multivariate logistic regression did not identify renal function as a predictor of operative success OR 1.00 (95% CI: 0.97-1.03) (p-value: 0.88). DISCUSSION The results of the present study suggest that low DRF alone is not associated with worse outcomes and shows no difference in the failure rate. The incidence and type of complications were not increased for the lower functioning groups. The main limitation of this study would be its retrospective nature and single-institution experience. Furthermore, post-operative functional studies were not available for all patients, limiting the ability to draw conclusions on the change in DRF after surgery. CONCLUSIONS In a large cohort, preoperative DRF was not predictive of pyeloplasty success rate. DRF ≤10% was not associated with higher incidence of complications or failure rate. The DRF alone should not dictate the management options available for patients with UPJO.

Abstract
Background Three-dimensional (3D) image reconstruction technology is widely used in surgical operations for its intuitive visualization. Pyeloplasty requiresprecise cutting and suturing. The reconstruction technology can accurately determine the location and scope of the stenosis at the junction of the renal pelvis and ureter and the relationship with the surrounding vasculature. The purpose of this article is to retrospective evaluate the application value of image reconstruction technology in pyeloplasty based on high-resolution 3D CT images. Methods A total of 20 patients with renal pelvic ureteral junction obstruction admitted to our hospital from August 2019 to August 2020 were selected. In this group, left pyeloplasty was performed in 8 patients and right pyeloplasty in 12 patients. In terms of conditions, there was 1 case with secondary pyeloplasty, 6 cases of patients with kidney stones, 2 cases with renal ectopic blood vessels, 1 case with renal prolapse, 1 case with horseshoe kidney, and 1 case with ureteral polyps. There were 12 males and 8 females, with an average age of 34.65±10.67 years and an average body mass index (BMI) of 22.48±3.03 kg/m2. In all patients, 3D CT reconstruction technology was used to guide the formulation of robot-assisted laparoscopic pyeloplasty plans; verify the consistency between the actual operation and the preoperative planning; and observe the operation time, blood loss, postoperative exhaust time, indwelling drainage tube time, and follow-up for comorbidities. Results The operation was successful in all 20 patients. The actual operation was 100% consistent with the preoperative planning, the operative time was 160.80±63.26 min, the intraoperative blood loss was 47±30.45 mL, the postoperative exhaust time was 1.15±0.37 days, the drainage tube indwelling time was 4.35±1.50 days, and the average follow-up time was 7.95±3.41 months. There were no complications. Conclusions Three-dimensional image reconstruction technology based on high-resolution CT has high clinical application value in the treatment of ureteropelvic junction obstruction (UPJO), which simplifies the operation process and shortens the operation time, and is a valuable tool for auxiliary surgeons in devising the operation plan.

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

Abstract
PURPOSE This study aimed to report a multi-institutional retrospective case series of outcomes after robot-assisted laparoscopic pyeloplasty (RALP) in pediatric patients with complex pelvi-ureteric junction obstruction (PUJO). METHODS All patients undergoing complex RALP over the last 5 years were included. RALP was defined complex in the following cases of PUJO: anatomic variations including ectopic, malrotated, horseshoe, or duplex kidney and recurrent PUJO after failed open pyeloplasty. RESULTS Forty-eight patients underwent complex RALP in four European centers in the study period and included 18 girls and 30 boys with a median age of 8 years (range 5-12). The PUJO was associated with anatomic variations in 35/48 (72.9%), whereas a recurrent PUJO was present in 13/48 (27.1%). A dismembered Anderson-Hynes pyeloplasty was performed in all patients. The median operative time including docking was 178.5 min (range 117-255) and the median anastomotic time was 64.8 min (range 50-76). All patients were discharged on 2nd postoperative day (POD). The median follow-up was 18.2 months (range 14-43). The overall success rate was 95.8% (46/48). Early postoperative complications (< 30th POD) included urinary tract infections (UTIs) and stent-related irritative symptoms in 4/48 (8.3%) [II Clavien], whereas late complications (> 30th POD) included recurrence of PUJO in 2/48 (4.2%), who needed re-operation [IIIb Clavien]. CONCLUSIONS RALP was safe, feasible, and with good mid-term outcome in complex PUJO. An accurate pre-operative planning, a standardized technique, and an experienced surgical robotic team represented key points to manage successfully such complex cases.

Abstract
PURPOSE The aim of this randomized controlled trial (RCT) is to compare the outcomes of conventional laparoscopic pyeloplasty (LP) versus robotic-assisted laparoscopic pyeloplasty (RALP) in the treatment of ureteropelvic junction obstruction (UPJO) in children. METHODS A total of 53 patients with UPJO were randomized as LP (Group 1, n: 27) and RALP (Group 2, n: 26). Redo cases and patients with anatomical abnormalities were excluded. Urinary ultrasound was performed at postoperative 3, 6 and 12 months; whereas, diuretic renal scintigraphy was performed at 1 year. Failure was defined as progressive hydronephrosis on ultrasound, decline in renal function, or symptom relapse. All parameters were statistically compared. RESULTS The mean age of the patients was 55.53 ± 57.25 months. There were no statistical differences between the groups in terms of patient gender, body mass index, laterality, preoperative renal function, renal pelvis antero-posterior diameter and presence of crossing vessel. Mean total operative time in LP group was longer than RALP (139 min vs 105 min, respectively, p = 0.001). The hospital stay was similar between the two groups. After a mean follow-up of 12.43 ± 5.34 months, the complication and success rates were found comparable. Only two patients required re-do pyeloplasty in LP group. The mean total cost of RALP procedure was approximately four times higher than LP. CONCLUSIONS This is the first RCT comparing LP and RALP in pediatric population. Both LP and RALP are safe and effective in children with comparable success and complication rates. Operative time was longer for LP; whereas, total cost was higher for RALP.

Abstract
Introduction Antegrade placement of double J stents in laparoscopy is considered a challenging and time-consuming process due to limitations regarding stent flexibility. Aim To describe the method we used to facilitate the antegrade placement of intracorporeal stents in laparoscopic upper urinary tract (LUUT) surgery and report its results. Material and methods Data obtained from 42 consecutive patients who had stents placed antegradely in laparoscopic pyeloplasty or in laparoscopic ureterolithotomy for middle-upper ureteral stones were retrospectively evaluated. The mean age of the patients was 30.1 ±18.6 (10 months–68 years) and 13 patients were in the paediatric age group. All patients in the paediatric age group underwent laparoscopic pyeloplasty. Results The mean operative time for the 42 total cases, of which 32 underwent laparoscopic dismembered pyeloplasty and 10 laparoscopic ureterolithotomy, was 126.9 ±33.5 (70–200) min and the intraoperative stent placement time was calculated as 2.61 ±0.8 (1.5–5) min. The patients, who had a mean hospitalization time of 2.8 ±0.9 (2–5) months, required no additional interventions and no complications were encountered intraoperatively. In the patient series that had a mean follow-up time of 17.4 ±11.3 (1–35), it was determined only in 1 patient that the distal tip of the stent had not been in the bladder. Conclusions The described modified antegrade stent placement technique is a practical method that is safe for all LUUT cases in both paediatric and adult age groups and it has been shown to produce successful outcomes and to be time-saving.

Abstract
BACKGROUND Single-site laparoscopy is increasingly popular for straightforward operations like appendectomy. Due to limited triangulation and maneuverability, single-site cholecystectomy is riskier and more difficult. Robotics offer to make it easier and safer. METHODS Twenty children and adolescents underwent robotic-assisted single-site cholecystectomy at a large academic children's hospital. Patients were not randomized; patients were offered the option of robotic-assisted single-site (SSR) or standard four-incision laparoscopic (LAP) cholecystectomy. Demographics and perioperative details were compared with those of a comparable cohort who underwent LAP during the same period. RESULTS The two groups were similar in physical characteristics and indications for operation. The robotic operations took longer but both groups received similar PRN doses of parenteral opiates. Patients in the SSR group were all discharged on the first postoperative day. There were no major complications in either group but a slightly higher incidence of minor wound complications in the SSR group. CONCLUSION Robotic-assisted single-site cholecystectomy appears to be a safe alternative to standard laparoscopy with a similar postoperative pain profile, short postoperative lengths of stay, and, for some, a superior cosmetic result. Nevertheless, it comes with longer set-up and operative times, a higher incidence of minor wound complications, an unknown but possibly higher risk of incisional hernia, and higher costs.

Abstract
INTRODUCTION Minimally invasive pyeloplasty (MIP) for ureteropelvic junction (UPJ) obstruction in children has gained popularity over the past decade as an alternative to open surgery. The present study aimed to identify the factors affecting complication rates of MIP in children, and to compare the outcomes of laparoscopic (LP) and robotic-assisted laparoscopic pyeloplasty (RALP). MATERIALS AND METHODS The perioperative data of 783 pediatric patients (<18 years old) from 15 academic centers who underwent either LP or RALP with an Anderson Hynes dismembered pyeloplasty technique were retrospectively evaluated. Redo cases and patients with anatomic renal abnormalities were excluded. Demographics and operative data, including procedural factors, were collected. Complications were classified according to the Satava and modified Clavien systems. Failure was defined as any of the following: obstructive parameters on diuretic renal scintigraphy, decline in renal function, progressive hydronephrosis, or symptom relapse. Univariate and multivariate analysis were applied to identify factors affecting the complication rates. All parameters were compared between LP and RALP. RESULTS A total of 575 children met the inclusion criteria. Laparoscopy, increased operative time, prolonged hospital stay, ureteral stenting technique, and time required for stenting were factors influencing complication rates on univariate analysis. None of those factors remained significant on multivariate analysis. Mean follow-up was 12.8 ± 9.8 months for RALP and 45.2 ± 33.8 months for LP (P = 0.001). Hospital stay and time for stenting were shorter for robotic pyeloplasty (P < 0.05 for both). Success rates were similar between RALP and LP (99.5% vs 97.3%, P = 0.11). The intraoperative complication rate was comparable between RALP and LP (3.8% vs 7.4%, P = 0.06). However, the postoperative complication rate was significantly higher in the LP group (3.2% for RALP and 7.7% for LP, P = 0.02). All complications were of no greater severity than Satava Grade IIa and Clavien Grade IIIb. DISCUSSION This was the largest multicenter series of LP and RALP in the pediatric population. Limitations of the study included the retrospective design and lack of surgical experience as a confounder. CONCLUSIONS Both minimally invasive approaches that were studied were safe and highly effective in treating UPJ obstruction in children in many centers globally. However, shorter hospitalization time and lower postoperative complication rates with RALP were noted. The aims of the study were met.
