J Robot Surg 2024; 18:285. [PMID: 39012421 PMCID: PMC11252211 DOI: 10.1007/s11701-024-02006-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Accepted: 06/01/2024] [Indexed: 07/17/2024]
Abstract
OBJECTIVE To investigate whether the panoramic view offered by robot-assisted laparoscopic pyeloplasty (RALP) reduces the likelihood of missing a crossing vessel compared to open pyeloplasty in cases where initial pyeloplasty fails. METHODS A single institution redo-pyeloplasty database was reviewed for children treated between January 2012 to July 2023. Clinical history, imaging and operative details were reviewed to identify the etiology for the redo procedure. RESULTS Cohort consisted of 45 patients undergoing a redo RALP during the study period. 29 of 45 patients had an initial open surgical approach, whereas 16 had an initial RALP. 10 patients were noted to have a missed crossing vessel on redo pyeloplasty - 9 had an initial open approach whereas 1 had an initial RALP (p<0.0001). CONCLUSIONS RALP may reduce the risk of missing a crossing vessel due to the panoramic view of the surgical field intrinsic to an intraperitoneal RALP approach.

Abstract
Congenital hydronephrosis can be classified and managed based on the Urinary Tract Dilation consensus scoring system. Ureteropelvic junction obstruction is one of the most common causes of hydronephrosis in the pediatric population. Although most cases can be managed conservatively with follow-up and serial imaging, some patients need surgical repair because of renal function deterioration, infections, or symptoms. Additional research to create predictive algorithms or develop noninvasive biomarkers for renal deterioration is necessary to better identify surgical candidates. The robotic-assisted approach for pyeloplasty is becoming increasingly widespread and associated with shorter hospital stay, high success rates, and low complication rates.

Abstract
PURPOSE Review the experience of redo laparoscopic pyeloplasty (RLP) in patients with recurrent ureteropelvic junction obstruction (UPJO) in comparison to primary laparoscopic pyeloplasty (PLP) and redo open pyeloplasty (ROP), and determine the feasibility and effectiveness of RLP for recurrent UPJO in children. METHODS We retrospectively reviewed the clinical data of patients treated with transperitoneal PLP, RLP, and ROP for UPJO from December 2015 to December 2022. The Propensity score matching (PSM) was used to balance confounding variables. RLP patients were 1:4 matched with PLP and 1:3 matched with ROP. The primary outcomes were failure and post-operative complications. Complications were classified according to the Clavien-Dindo grading system. RESULTS The study included ten patients who underwent RLP, 43 patients who underwent ROP, and 412 patients who underwent PLP. The follow-up time ranged from 6 to 36 months in the RLP group, 12 to 60 months in the PLP group, and 24 to 54 months in the ROP group. In the RLP group, no failure but three post-operative complications (Clavien grade II) were observed during the follow-up. Compared with the PLP group, the older age, higher weight, larger pre-operative anteroposterior diameter (APD) and APD/cortical thickness (P/C ratio), longer operation time, and post-operative length of stay (LOS) in the RLP group (P < 0.05). After PSM, longer operation time and post-operative LOS were observed in the RLP group (P < 0.05). Compared with the ROP group, the older age, higher weight, and longer post-operative LOS in the RLP group (P < 0.05). After PSM, longer post-operative LOS was observed in the ROP group (P < 0.05). The failure and complication rates were comparable between RLP and PLP or RLP and ROP (P > 0.05). CONCLUSIONS Our result demonstrated that RLP performed as well as PLP except for a longer operation time. Compared with ROP, RLP has the advantages of a clearer surgical view, sufficient exposure, clearer anatomical landmark position, and minor trauma with a comparable clinical outcome. On experienced hands, RLP for recurrent UPJO after is a safe and effective procedure and should be considered an excellent alternative to the more commonly recommended ROP in select patients.

Personalized application of machine learning algorithms to identify pediatric patients at risk for recurrent ureteropelvic junction obstruction after dismembered pyeloplasty. World J Urol 2021; 40:593-599. [PMID: 34773476 DOI: 10.1007/s00345-021-03879-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 11/02/2021] [Indexed: 11/27/2022] Open
Abstract
PURPOSE To develop a model that predicts whether a child will develop a recurrent obstruction after pyeloplasty, determine their survival risk score, and expected time to re-intervention using machine learning (ML). METHODS We reviewed patients undergoing pyeloplasty from 2008 to 2020 at our institution, including all children and adolescents younger than 18 years. We developed a two-stage machine learning model from 34 clinical fields, which included patient characteristics, ultrasound findings, and anatomical variation. We fit and trained with a logistic lasso model for binary cure model and subsequent survival model. Feature importance on the model was determined with post-selection inference. Performance metrics included area under the receiver-operating-characteristic (AUROC), concordance, and leave-one-out cross validation. RESULTS A total of 543 patients were identified, with a median preoperative and postoperative anteroposterior diameter of 23 and 10 mm, respectively. 39 of 232 patients included in the survival model required re-intervention. The cure and survival models performed well with a leave-one-out cross validation AUROC and concordance of 0.86 and 0.78, respectively. Post-selective inference showed that larger anteroposterior diameter at the second post-op follow-up, and anatomical variation in the form of concurrent anomalies were significant model features predicting negative outcomes. The model can be used at https://sickkidsurology.shinyapps.io/PyeloplastyReOpRisk/ . CONCLUSION Our ML-based model performed well in predicting the risk of and time to re-intervention after pyeloplasty. The implementation of this ML-based approach is novel in pediatric urology and will likely help achieve personalized risk stratification for patients undergoing pyeloplasty. Further real-world validation is warranted.

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
PURPOSE The purpose of the study was to assess the outcomes of salvage procedures after failed pediatric pyeloplasty. Recurrent ureteropelvic junction obstruction treatment is a difficult course. The salvage surgery is more challenging in the pediatric population. We aimed to assess the outcomes of salvage procedures after failed pediatric pyeloplasty to determine the most efficient surgical intervention. METHODS 40 children with 41 renal units who have been treated for recurrent ureteropelvic junction obstruction after pyeloplasty were analyzed retrospectively. The outcomes of all initial and sequent interventions were assessed including redo pyeloplasty, endopyelotomy and balloon dilatation. RESULTS Children's mean age at initial intervention for failed pyeloplasty was 45.9 (± 46.4) months. Our mean follow-up time after the initial intervention was 46.9 (± 46.6) months. The success rate of our initial treatment methods was 48.7% (20/41). Although redo pyeloplasty was the most successful intervention (83.3%) than DJS placement (45.5%), endopyelotomy (50%) and balloon dilatation (30.8%), the statistical difference was not significant in the initial operations. The overall success rates of redo pyeloplasty, double-J stent placement, endopyelotomy and balloon dilatation were 78.9%, 46.1%, 38.8% and 29.4%, respectively (p < 0.05). CONCLUSIONS Redo pyeloplasty provides the best improvement in recurrent ureteropelvic junction obstruction in children. In selected patients, minimal invasive methods such as endopyelotomy and balloon dilatation offer alternative treatment.

Abstract
INTRODUCTION Laparoscopic pyeloplasty (LP) has been widely used in the treatment of pediatric ureteropelvic junction obstruction (UPJO). However, no prior reports with a large pediatric series have focused on the analysis of complications and impact factors of the outcomes. We hypothesized there were risk factors of higher Clavien grade postoperative complications. OBJECTIVE To analyze the characteristics of complications and risk factors of high Clavien grade postoperative complications. PATIENTS AND METHODS All children with UPJO treated with primary transperitoneal LP between July 2016 and July 2018 were retrospectively reviewed. The Clavien complication grades in groups with different weight, intraoperative complication (drainage methods), anteroposterior pelvic diameters (APPD), side, gender, title of surgeon, preoperative presentation and obstruction reason were compared. RESULTS Of the 279 children, intraoperative complications in which the placement of double-J stents was not accomplished and conversion to open surgery (Satava grade II) occurred in 17 (6.09%) and 2 (0.72%) patients, respectively. A total of 270 patients (277 kidneys) were included in the analysis of postoperative complications. Postoperative complications occurred in 51 (18.89%) patients. The most frequent postoperative incident was febrile UTI in 27 patients. Of the 13 patients who required reoperations, 6 patients had kidney restenosis and were considered as failure of surgery. All complications with an exact onset time occurred within 10 months after surgery. In the univariate and multivariate analysis, weight <10 kg and having intraoperative complication with nephrostomy tube were risk factors of higher Clavien postoperative complication grade (P<0.05). DISCUSSION Patients who were <10 kg in weight and having intraoperative complication with nephrostomy tube had a greater risk of a higher Clavien grade postoperative complication. To reduce high Clavien grade postoperative complications, asymptomatic patients under 10 kg in weight and having intraoperative complication with nephrostomy tube need close monitoring. In the 26 patients who had an exact time of the postoperative complications, the longest time we found was 10 months. Thus, we recommend the follow-up time required to observe postoperative complications in patients should be at least 10 months after surgery. CONCLUSIONS LP has been proven to be safe and effective in children with a low rate of complications. Weight <10 kg and having intraoperative complications with nephrostomy tube were risk factors of higher Clavien grade postoperative complications. Children with low weight and intraoperative complications need more attention in terms of the occurrence of complications.

Searching for the Least Invasive Management of Pelvi-Ureteric Junction Obstruction in Children: A Critical Literature Review of Comparative Outcomes. Front Pediatr 2020; 8:252. [PMID: 32582587 PMCID: PMC7280432 DOI: 10.3389/fped.2020.00252] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Accepted: 04/22/2020] [Indexed: 01/22/2023] Open
Abstract
Introduction: To review the published evidence on the minimally invasive pyeloplasty techniques available currently with particular emphasis on the comparative data about the various minimally invasive alternatives to treat pelvi-ureteric junction obstruction and gauge if one should be favored under certain circumstances. Materials and Methods: Non-systematic review of literature on open and minimally invasive pyeloplasty including various kinds of laparoscopic procedures, the robotic-assisted laparoscopic pyeloplasty, and endourological procedures. Results: Any particular minimally invasive pyeloplasty procedure seems feasible in experienced hands, irrespective of age including infants. Comparative data suggest that the robotic-assisted procedure has gained wider acceptance mainly because it is ergonomically more suited to surgeon well-being and facilitates advanced skills with dexterity thanks to 7 degrees of freedom. However, costs remain the major drawback of robotic surgery. In young children and infants, instead, open surgery can be performed via a relatively small incision and quicker time frame. Conclusions: The best approach for pyeloplasty is still a matter of debate. The robotic approach has gained increasing acceptance over the last years with major advantages of the surgeon well-being and ergonomics and the ease of suturing. Evidence, however, may favor the use of open surgery in infancy.

Abstract
Background Multiple surgical treatment options are available for the treatment of ureteropelvic junction obstruction (UPJO). The aim of this study is to compare the most frequently used technics in a comprehensive network approach. Methods A systematic literature search of the EMBASE, MEDLINE and COCHRANE libraries was conducted in January 2018. Publications were included that evaluated at least two of the following surgical techniques: open pyeloplasty (OP), endopyelotomy (EP), laparoscopic (LP) and robot assisted pyeloplasty (RP). Main outcomes were operative success, complications, urinary leakage, re-operation, transfusion rate, operating time, and length of stay. Network meta-analyses with random effects models simultaneously assessed effectiveness of all surgical techniques. Results A total of 26 studies including 3143 patients were analyzed. Compared with RP, EP and LP showed lower operative success rates (EP: OR = 0.09, 95%CI:0.05–0.19; p < 0.001; LP: OR = 0.51, 95%CI:0.31–0.84; p = 0.008). Compared with OP, LP and RP had lower risk for complications (LP: OR = 0.62; 95%CI:0.41–0.95; p = 0.027; RP: OR = 0.41; 95%CI:0.22–0.79; p = 0.007). Compared with RP, no significant differences were detected for urinary leakage or re-operation, transfusion rates. Compared with EP, RP yielded longer operating time (mean = 102.87 min, 95%CI:41.79 min–163.95 min, p = < 0.001). Further significant differences in operating times were detected when comparing LP to EP (mean = 115.13 min, 95%CI:65.63 min–164.63 min, p = < 0.001) and OP to EP (mean = 91.96 min, 95%CI:32.33 min–151.58 min, p = 0.003). Conclusions Multiple surgical techniques are available for treatment of UPJO. RP has the highest rates of operative success and as well as LP lower complication rates than OP. Although surgical outcomes are worse for EP, its operating time is shorter than OP, RP, and LP. Surgeons should consider these findings when selecting the optimal treatment method for individual patients.

Abstract
Retroperitoneal laparoscopic pyeloplasty (RLP) is 1 method for treating ureteropelvic junction obstruction (UPJO) in children, but reports are more common in children than in infants younger than 2 years old. The purpose of this study was to evaluate the clinical value of RLP for infants with UPJO.From January 2015 to December 2017, a retrospective analysis of 22 infants aged 2 to 24 (11.95 ± 6.00) months with UPJO who were treated with RLP in our hospital was performed. During the same period, 14 infants who underwent conventional transperitoneal laparoscopic pyeloplasty (TLP) were compared with those who underwent RLP. Postoperative recovery and complications, including bleeding, infection, urinary leakage and anastomotic stenosis, postoperative resumption of oral feeding, postoperative hospitalization time and surgical success rate were evaluated. Drainage and function were assessed with isotope scan at 6 months and later during the yearly follow-up and by intravenous urography (IVU) and mercaptoacetyltriglycine (MAG3) renography.Both groups underwent successful surgery. The operative time in the RLP group was 88 to 205 (120.59 ± 24.59) min, and there was no significant difference compared with the TLP group (P = .767). The estimated intraoperative blood loss was 2 to 10 (3.75 ± 1.59) ml, which was not significantly different between the 2 groups (P = .386). In the RLP group, the mean postoperative resumption of oral feeding was faster than that in the TLP group (3.55 ± 0.74 vs 5.50 ± 0.85 hour, P < .001), and the postoperative hospitalization time was shorter in the TLP group than in the RLP group (6.59 ± 0.50 vs 7.07 ± 0.47 day, P = .007 < .05). Follow-up lasted from 6 months to 3 years, and there was a significant reduction in postoperative hydronephrosis in both groups (P < .05, respectively).RLP is a safe procedure for infants. This procedure is associated with relatively little trauma, a quick recovery and good cosmetic effects. RLP also has the advantages of relatively little interference with the abdominal cavity and sufficient operating space; thus, this technique is worth promoting.

Is secondary robotic pyeloplasty safe and effective as primary robotic pyeloplasty? A systematic review and meta-analysis. J Robot Surg 2019; 14:241-248. [PMID: 31280462 DOI: 10.1007/s11701-019-00997-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Accepted: 07/02/2019] [Indexed: 12/14/2022]
Abstract
Robot-assisted laparoscopic pyeloplasty (RLP) has excellent surgical safety and efficacy in primary pyeloplasty. In recent, the application of robotics has explored to more complex surgical conditions such as failed pyeloplasty. This meta-analysis aimed to evaluate the surgical and clinical outcomes of secondary RLP compared with primary RLP. Following PRISMA guidelines, we carried out an extensive literature search in the PubMed, Web of Science, Cochrane Library, Scopus, and Google Scholar to extract the published articles comparing primary vs. secondary RLP up to April 2019. Interested surgical and clinical outcomes were extracted from each study and then used RevMan 5.3 Software for meta-analysis comparison. Furthermore, the quality of each study was assessed using the Modified Newcastle-Ottawa Scale for cohort studies. Our search has yielded seven studies that met our inclusion criteria. These studies contained 613 vs. 107 patients in primary vs. secondary RLP, respectively. Using random effect model, the analysis showed no statistical difference between the groups in the presence of a crossing vessel, complications, length of hospital stays (LOS), and follow-up period. However, the operative time, estimated blood loss (EBL), and recurrence rate were significantly higher in the secondary RLP compared with primary RLP (p = 0.004), (p = 0.01), and (p = 0.04), respectively. Our results indicate that secondary RLP is associated with significantly increased operative time and EBL and higher recurrence rates compared with primary RLP. We believe that our findings might help surgeon's decision making in patient selection and consultation during redo pyeloplasty surgical planning.

Abstract
Objective To report the outcomes and complications of open dismembered Anderson-Hynes pyeloplasty with miniature incision in treating children's ureteropelvic junction obstruction. Methods Between March 2007 and April 2011, 109 children with a mean age of 2 years and 8 months old with ureteropelvic junction obstruction underwent open dismembered pyeloplasty. Clinical manifestations, radiographic assessments, incision size, surgery time, hospital stay, and complication rate were recorded. All patients had a documented ureteropelvic junction obstruction (having T1/2 more than 20 min in diethylenetriaminepentaacetic acid [DTPA] scan) with symptomatic stenosis or decreased kidney function (differential function <40%). Pyeloplasty was done by a retroperitoneal flank approach with miniature incision without pelvis reduction. One surgeon did all the surgeries. Success rate and complications were assessed in a 3-year follow-up. Results Mean surgery time was 52 min (47–60 min). Incision size was 18–28 mm. Mean hospital stay was 3 days (2–8 days). The surgery was successful in 98.2% of patients with a mean follow-up time of 36 months (success was defined as disappearance of symptoms, if present, with improved ultrasound imaging results or Reno graphic parameters). The complication rate was 7.33%, including urinary leakage, double-J urethral stent dislocation and infection. Conclusion Open dismembered pyeloplasty is a safe, technically feasible and effective therapy in treatment of children's ureteropelvic junction obstruction. It takes a short time to do, requires a small incision and has few complications and a short recovery period.

[PMID: 28384296 PMCID: PMC5383307 DOI: 10.1371/journal.pone.0175213] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2016] [Accepted: 03/22/2017] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVE Our objective was to evaluate quality of conduct and reporting of published systematic reviews and meta-analyses in paediatric surgery. We also aimed to identify characteristics predictive of review quality. BACKGROUND Systematic reviews summarise evidence by combining sources, but are potentially prone to bias. To counter this, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was published to aid in reporting. Similarly, the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) measurement tool was designed to appraise methodology. The paediatric surgical literature has seen an increasing number of reviews over the past decade, but quality has not been evaluated. METHODS Adhering to PRISMA guidelines, we performed a systematic review with a priori design to identify systematic reviews and meta-analyses of interventions in paediatric surgery. From 01/2010 to 06/2016, we searched: MEDLINE, EMBASE, Cochrane, Centre for Reviews and Dissemination, Web of Science, Google Scholar, reference lists and journals. Two reviewers independently selected studies and extracted data. We assessed conduct and reporting using AMSTAR and PRISMA. Scores were calculated as the sum of reported items. We also extracted author, journal and article characteristics, and used them in exploratory analysis to determine which variables predict quality. RESULTS 112 articles fulfilled eligibility criteria (53 systematic reviews; 59 meta-analyses). Overall, 68% AMSTAR and 56.8% PRISMA items were reported adequately. Poorest scores were identified with regards a priori design, inclusion of structured summaries, including the grey literature, citing excluded articles and evaluating bias. 13 reviews were pre-registered and 6 in PRISMA-endorsing journals. The following predicted quality in univariate analysis:, word count, Cochrane review, journal h-index, impact factor, journal endorses PRISMA, PRISMA adherence suggested in author guidance, article mentions PRISMA, review includes comparison of interventions and review registration. The latter three variables were significant in multivariate regression. CONCLUSIONS There are gaps in the conduct and reporting of systematic reviews in paediatric surgery. More endorsement by journals of the PRISMA guideline may improve review quality, and the dissemination of reliable evidence to paediatric clinicians.

Front Pediatr 2016; 4:72. [PMID: 27458574 PMCID: PMC4937023 DOI: 10.3389/fped.2016.00072] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2016] [Accepted: 06/30/2016] [Indexed: 12/28/2022] Open
Abstract
PURPOSE The aim of this study is to analyze results of retrograde endopyelotomy with cutting balloon for treatment of ureteropelvic junction obstruction (UPJO) in infants. METHODS We routinely treat patients with UPJO under 18 months of age with retrograde high-pressure balloon dilatation of the pelviureteric junction (PUJ). During the procedure, in these cases where narrowing at the PUJ persists, endopyelotomy with cutting balloon is performed. Endopyelotomy is performed over guidewire with 5-mm Cutting Balloon™ under fluoroscopic control. Double-J stents is left in situ for 4 weeks. We retrospectively analyzed the postoperative, clinical, and radiological outcome infants treated with cutting balloon endopyelotomy between 2007 and 2015. RESULTS Sixteen patients required cutting balloon endopyelotomy to achieve complete resolution of narrowing of the waist observed during high-pressure balloon dilatation of the PUJ. Mean operative time was 35 ± 21 min (mean ± SD) and hospital stay was <24 h in all patients. Complete resolution of the narrowing at the PUJ under fluoroscopy was achieved in all cases, with no perioperative complications. One patient presented with urinary tract infection, postoperatively (Clavien grade II). Preoperatively, all cases had grade IV SFU hydronephrosis with parenchymal thinning. During follow-up, resolution of the hydronephrosis was observed in 11 patients (grade I SFU). In four infants, there was an improvement of the hydronephrosis (grade II SFU) and the renogram curve. In one case, an open pyeloplasty was required due to persistent hydronephrosis and obstructive curve. CONCLUSION We believe that endopyelotomy with cutting balloon could be a valid and safe option in minimally invasive management of UPJO in infants.
