Asian J Surg 2024:S1015-9584(24)00602-X. [PMID: 38614849 DOI: 10.1016/j.asjsur.2024.03.175] [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: 04/26/2023] [Revised: 11/08/2023] [Accepted: 03/28/2024] [Indexed: 04/15/2024] Open
Abstract
OBJECTIVE To investigate the feasibility of single-port (SP) robotic pyeloplasty by comparing perioperative outcomes with those of multiport (MP) robotic pyeloplasty. MATERIALS AND METHODS We reviewed the data from patients who underwent robot-assisted pyeloplasty for ureteropelvic junction obstruction (UPJO) at a single tertiary institution between March 2016 and May 2022. Radiographic and symptomatic improvements were assessed 3 months postoperatively. Propensity score matching was performed for age, sex, body mass index, and hydronephrosis grade. RESULTS Of the 15 S P-pyeloplasty and 28 MP-pyeloplasty cases, 14 from each group were matched using 1:1 matching. The SP group had shorter console and operative times without significant differences. Blood loss was lower in the SP group than in the MP group (p = 0.019). The length of hospital stay, opioid use on the operative day, and pain score at discharge did not differ between the two groups. The mean cost for surgery was higher in the SP group than in the MP group (p < 0.001). The mean cost of hospitalization was comparable between the two groups (p = 0.083). The cosmetic numerical rating scale scores were significantly higher in the SP group (p = 0.014). Symptoms improved in all patients, and the radiographic improvement rates were 92.9% in the SP group and 100% in the MP group. CONCLUSION SP-pyeloplasty showed cosmetic benefits, lower blood loss, operative time, and console time compared with MP-pyeloplasty. In patients who underwent surgery for UPJO for the first time, SP surgery can show comparable outcomes when compared to MP surgery.

Abstract
Objective This study was conducted to explore the risk factors for the prognosis and recurrence of ureteropelvic junction obstruction (UPJO). Methods The correlation of these variables with the prognosis and recurrence risks was analyzed by binary and multivariate logistic regression. Besides, a nomogram was constructed based on the multivariate logistic regression calculation. After the model was verified by the C-statistic, the ROC curve was plotted to evaluate the sensitivity of the model. Finally, the decision curve analysis (DCA) was conducted to estimate the clinical benefits and losses of intervention measures under a series of risk thresholds. Results Preoperative automated peritoneal dialysis (APD), preoperative urinary tract infection (UTI), preoperative renal parenchymal thickness (RPT), Mayo adhesive probability (MAP) score, and surgeon proficiency were the high-risk factors for the prognosis and recurrence of UPJO. In addition, a nomogram was constructed based on the above 5 variables. The area under the curve (AUC) was 0.8831 after self cross-validation, which validated that the specificity of the model was favorable. Conclusion The column chart constructed by five factors has good predictive ability for the prognosis and recurrence of UPJO, which may provide more reasonable guidance for the clinical diagnosis and treatment of this disease.

Abstract
To explore the learning curve of robot-assisted laparoscopic pyeloplasty (RALP) in children. The clinical data, surgical information, and postoperative complications of consecutive cases of RALP performed by the same surgeon in Shanghai Children's Hospital from January 2014 to July 2020 were retrospectively analyzed; the surgeon is a senior pediatric urologists who is proficient in laparoscopic pyeloplasty; the data consist of console time (CT), suture method when anastomosing ureteropelvic junction (UPJ), number of stitches (N), anastomosis time per stitch (tn), the average suture time per stitch (T) = (suture time of first stitch (t1) + second stitch (t2) + … + tn)/N, postoperative complications, and surgical outcome. The learning curve was depicted by cumulative sum method (CUSUM) and validated by cumulative method (CUM). Of the 88 cases, 64 cases were included in present study. Median CT was 104 (83-117) min, mean T was 109 ± 17 s. There were ten cases of Clavien-Dindo Grade I complication and two cases of Clavien-Dindo Grade IIIb complication. The median follow-up time was 237 (87-627) days. The learning curve of CT has three stages, with inflection points at 11th and 57th case, and T has two stages, with inflection points at 19th case. There was a statistically significant difference between the console time and length of stay on both sides of the inflection point (P < 0.05), but there was no statistically significant difference in age, gender, etiology, clinical manifestation, surgical outcome, and complication (P > 0.05). For a senior pediatric urologists who is proficient in laparoscopic pyeloplasty, the learning curve of RALP can be divided into three stages, preliminary exploration stage, mastery stage, and proficiency stage. It takes about 11 cases to achieve the mastery stage, and it takes about 57 cases to achieve the proficiency stage. The learning curve focused on the suture technique of the surgeon is divided into two stages, and after a learning period of 19 cases, it will reach the proficiency stage of suturing UPJ.

Abstract
Robotic pyeloplasty has become a technique of choice for pyelo-ureteral junction syndrome treatment in children. Less invasive than open surgery, robotic pyeloplasty also has a lower learning curve than laparoscopic pyeloplasty. This is how a new generation of surgeons without previous laparoscopic pyeloplasty experience has begun training in robotics. To assess the robotic assisted pyeloplasty learning curve for a pediatric surgeon only trained in open pyeloplasty, and to investigate if that mode of practice is safe and effective. Data were collected from all children operated on for pyelo-ureteral junction syndrome by the same surgeon in our center between 2015 and 2021. Cases were divided into 4 groups of 14 consecutive procedures to analyze the learning curve. Fifty-six patients were operated on, with a median (IQR) age, weight, and hospital stay of 9 years and 1 month old (3.5), 29 kg (17.3), and 3 days (2), respectively. The mean ± SD operative times were 146.5 ± 39.3, 123.2 ± 48.1, 103.1 ± 29.5, and 141.7 ± 25.0 min, with a unique significant difference between groups 1 and 3 (p = 0.007**). Only two intraoperative and nine postoperative complications were observed. The surgery was successful in 98% cases. Our study shows that a significant improvement in surgical time could be achieved in the first 30 cases, safely and efficiently even without previous laparoscopic pyeloplasty experience.Level of evidence: III.

Abstract
Pyeloplasty is considered the gold standard for the management of ureteropelvic junction obstruction in cases of flank pain, recurrent stone formation or infection, and deteriorating renal function. Over the last two decades, minimally invasive techniques such as robotic (RALP) and laparoscopic pyeloplasty (LP) have become increasingly popular and have been moderately replacing the open approach. This paper aims to provide a comprehensive up-to-date review on safety, efficacy and outcomes regarding robotic repair of UPJO compared to the conventional laparoscopic procedure. RALP represents a viable and innovative alternative to conventional LP with a comparable success and complication rate both in adult and in paediatric fields. The robotic approach seems to add further technical advantages when compared to conventional LP but sustains a higher costs. Currently, the choice to adopt one of the different minimally invasive approaches depends on the surgeon's preference or experience, and on institutional availability.
