J Pediatr Surg 2024; 59:1170-1176. [PMID: 38158254 DOI: 10.1016/j.jpedsurg.2023.11.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 11/19/2023] [Accepted: 11/22/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Standard protocol for post-pyeloplasty monitoring in children and natural course of hydronephrosis resolution have not been well defined. We aimed to analyze critical time intervals and risk factors in the long-term clinical outcomes of children who were operated for ureteropelvic junction obstruction. METHODS Files of patients who underwent open dismembered pyeloplasty between January 2000 and December 2012 and had a ≥10 years follow-up were retrospectively reviewed. Changes in SFU hydronephrosis grade, pelvis anteroposterior diameter (APD), renal parenchymal thickness, split renal functions (SRF) on MAG-3 scan as well as development of hypertension and proteinuria were noted. Complete resolution was defined as SFU grade 0-1 or APD≤10 mm or ≥50 % APD decrease. RESULTS Overall, 223 patients (161 boys, 72.1 %) with a median age of 9 (range 1-185) months underwent unilateral pyeloplasty, whereas 14 patients (13 boys, 92.8 %) with a median age of 4 (range 2-39) months underwent bilateral pyeloplasty. Median follow-up was 13 (range 10-22) years. Complete resolution was observed in 190 patients (85.2 %). None of the cases required re-do pyeloplasty. Regarding unilateral cases, postoperative changes in hydronephrosis reached a plateau at the 60th month. Also, there was no significant difference regarding SRF between the 12th month and the 60th month (p > 0.05). Hypertension developed after a median period of 12 years in 13 (5.4 %) of the patients, while proteinuria developed in four (1.6 %) patients. Bilateral disease (HR: 2.518, p = 0.034) was found to be a significant determinant for development of hypertension and/or proteinuria. CONCLUSIONS Our results indicated that ultrasonographic findings stabilized after the 60th month postoperatively, and SRF remained stable between the postoperative 12th and the 60th months. The risk of developing hypertension and/or proteinuria was 2.5 times greater in bilateral cases. LEVEL OF EVIDENCE Level II.

Abstract
OBJECTIVE To evaluate the efficacy and safety of robot-assisted laparoscopic pyeloplasty (RALP) and describe the short and long-term outcomes of pediatric RALP. METHODS We retrospectively reviewed all patients ..±21 years old who underwent primary RALP from 7/2007 through 12/2019. Patients were excluded from postoperative analysis if follow-up data after stent removal was not available. The primary outcome was surgical success, defined as radiographic improvement of hydronephrosis without need for reoperation. Secondary outcomes were time to reoperation and 90-day complication rate. RESULTS A total of 356 patients underwent primary repair of ureteropelvic junction obstruction during the study period; 29.ßpatients were limited to intraoperative data due to lack of follow-up imaging. Radiographic improvement at latest follow-up was seen in 308/327 (94.2%). Ten of 327 patients (3.1%) underwent reoperation: 7 were identified within 1 year of RALP and 3 were identified over 1 year after RALP. The median time to reoperation was 13.0 months (IQR 9.3-21.7). We defined long-term as>3 years after pyeloplasty. Over one-third (122/327, 37.3%) of the cohort had>3 years of follow-up, none of whom developed evidence of recurrent obstruction requiring reoperation beyond 3 years. Complications occurred within 90 days of surgery in 20/327 (6.1%). CONCLUSION This largest single-institution series confirms short- and long-term surgical effectiveness and safety of RALP. Our data also indicate that most patients who needed reoperation were identified within 1 year, and reoperation more than 3 years after RALP is rare.

Functional recoverability post-pyeloplasty in children with ureteropelvic junction obstruction and poorly functioning kidneys: Systematic review. J Pediatr Urol 2022; 18:616-628. [PMID: 35970740 DOI: 10.1016/j.jpurol.2022.07.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 07/12/2022] [Accepted: 07/15/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND The management of poorly functioning kidneys (PFK) associated with ureteropelvic junction obstruction (UPJO) is controversial. There is contradictory information about how to best manage these cases: pyeloplasty or nephrectomy? OBJECTIVE To systematically summarize the available evidence concerning the effects of pyeloplasty on the differential renal function of PFK in children with unilateral UPJO, highlighting the ongoing challenges in their definition, management, and long-term follow-up. In addition, we aim to verify potential predictors of renal functional recoverability that could help clinicians choose candidates for pyeloplasty. METHODS We searched several databases including PubMed, Embase, and Cochrane Library CENTRAL until August 20, 2021, according to the PRISMA guidelines. The following concepts were searched: pediatric, ureteropelvic junction obstruction, UPJO, pyeloplasty, recovery, split renal function, and differential renal function. We enrolled studies where the PFK was defined as preoperative differential renal function (DRF) ≤30% by renal scintigraphy. Potential predictors of renal functional recoverability were assessed and compared among studies. The quality of the included studies was evaluated using a modified version of the Newcastle-Ottawa scale (NOS). RESULTS 1499 citations perceived as relevant to screening were retrieved. After screening, 20 studies were included, comprising a total of 625 cases. The number of patients in each study varied between 5 and 84, while the average post-surgical follow-up duration ranged between 3 months and 180 months. The most significant preoperative predictive factor for postoperative functional recoverability was the baseline DRF, especially when antenatally diagnosed. The quality was considered average in a significant portion of included studies. CONCLUSION A significant proportion of PFK showed an increase of DRF post-pyeloplasty. However, no consistent predictive factors for functional recoverability have yet been determined apart from preoperative DRF. Until further evidence appears, pyeloplasty should be considered a valid option in the armamentarium of UPJO management in PFK.

Ultrasonographic stabilization of hydronephrosis after pyeloplasty: Key determinant of postoperative follow-up? J Pediatr Urol 2022; 18:662.e1-662.e7. [PMID: 36085189 DOI: 10.1016/j.jpurol.2022.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 07/18/2022] [Accepted: 08/09/2022] [Indexed: 12/14/2022]
Abstract
INTRODUCTION Although more than 1500 pediatric pyeloplasties are performed in the United States per year, there is a lack of consensus on the adequate imaging modality and timing of follow-up after surgery. OBJECTIVE The aim of this study is to evaluate if ultrasonographic stabilization in the grade of hydronephrosis after pyeloplasty is an adequate parameter to define the optimal length of follow-up after surgery and to detect failed procedures. Secondarily, we want to analyze clinical variables that could impact ultrasonographic stabilization. STUDY DESIGN This is a retrospective chart review of patients who underwent pyeloplasty between 2012 and 2020. Patients were included if they were ≤21 years-old at the time of surgery, had pre and postoperative renal-ultrasounds, had ≥3 months of postoperative follow-up, and had met the criteria for ultrasonographic stabilization after surgery. Ultrasonographic stabilization was defined as 2 consecutive ultrasounds after pyeloplasty, a minimum of 1-month apart, with the same degree of hydronephrosis according to the Society for Fetal Urology (SFU) grading system. Data concerning clinical, surgical, and postoperative variables were collected. RESULTS A total of 143 pyeloplasties met the inclusion criteria. Median age at surgery was 10.5 months with a median post-operative follow-up time of 29 months. Ultrasonographic stabilization was achieved in a mean time of 14.5 months post-operatively. Compared to the preoperative US SFU grade, at ultrasonographic stabilization 127 (88.9%) patients had an improvement of ≥1 grades of hydronephrosis. There were 9 pyeloplasty failures that were diagnosed and surgically corrected in a median of 7.5 months after the initial surgery. No clinical or surgical variables were associated with time to achieve ultrasonographic stabilization. DISCUSSION There is great variability in the length of follow-up after pyeloplasty, ranging from 3-months to 7-years. In our cohort, the bast majority of patients had achieved ultrasonographic stabilization and displayed improvement in their initial grade of hydronephrosis by 14.5 months after surgery. Timeframe in which surgical failures were diagnosed and corrected. There were not clinical or surgical variables associated to time to achieve stabilization. Similar results have been reported in the literature; however, most of them have evaluated as their main outcome resolution and not stabilization of hydronephrosis. CONCLUSION Ultrasonographic stabilization is a suitable and non-invasive parameter for determining the length of follow-up after unilateral pyeloplasty, as it is an adequate timeframe for identifying failed pyeloplasties, observing improvement or stabilization of hydronephrosis, and performing any additional procedure required after the primary repair.

Abstract
BACKGROUND Pediatric bronchial asthma signifies a frequent chronic inflammatory airway disorder influencing many children. Despite its irrefutable importance, its exact pathogenesis is not completely elucidated. AIM OF THE STUDY The study aimed to investigate the correlation between mitophagy machinery proteins, ER stress biomarkers and total polyamine and their role in disease progression via targeting NF-κB mechanisms. METHODS Sixty children with atopic bronchial asthma were enrolled in the study, they were allocated into 2 equal groups (mild/moderate and severe atopic asthmatic groups). Thirty age-matched healthy control subjects were also included in the study to represent the control group. Phosphatase and tensin homolog (PTEN)-induced kinase-1 (PINK-1) and Parkin messenger RNA (mRNA) expressions were assessed by (RT-PCR) technique. Levels of inositol requiring enzyme 1α (IRE1α), total polyamines, interleukin 6 & 8 (IL-6, IL-8) and nuclear factor kappa B (NF-κB) were assessed by enzyme-linked immunosorbent assay. Oxidative stress (OS) biomarkers were also measured. RESULTS PINK-1 and PARK mRNA expressions were significantly upregulated in asthmatic patients. Likewise, the level of IRE1α, total polyamines, inflammatory cytokines, and OS biomarkers were significantly elevated in asthmatic groups comparing to control group with the highest levels noticed in severe atopic asthmatic group. CONCLUSION the study documented a correlation between mitophagy machinery proteins, ER stress biomarkers and total polyamines that may pave a new platform to understand pediatric asthma pathogenesis and could be used as reliable biomarkers to evaluate disease progression.

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
BACKGROUND Dismembered pyeloplasty is considered the gold standard treatment for ureteropelvic junction obstruction (UPJO). Although the frequency and timing of follow up imaging after pyeloplasty is variable, renal ultrasound (RUS) is commonly utilized. With minimal training, point-of-care ultrasound (POCUS) can be easily performed by a urologist during a post-operative visit. OBJECTIVE Our hypothesis is that POCUS is an accurate, time-saving, and cost-effective alternative to a complete retroperitoneal ultrasound (CRUS) performed by the Radiology Department after pyeloplasty. STUDY DESIGN The clinical records of all children who underwent pyeloplasty (by any method) over a 12 month period at our institution were retrospectively reviewed. The exact timing and method (POCUS vs. CRUS) of follow up imaging was surgeon-dependent. Statistical analysis was performed to compare the time and cost of POCUS vs. CRUS. The clinical course of each patient who had each type of imaging was assessed. RESULTS A total 45 patients were included in this analysis. Over a mean follow up period of 29 months, a total of 73 CRUS and 67 POCUS were performed. Each CRUS on average added 2 h to each patient's healthcare encounter. Had the 73 CRUS been performed as POCUS instead, this would have corresponded to $83,751 less charges to payers. There was no difference in the rate of the detection of worsening, stable, or improved hydronephrosis (HN) between either modality (p > 0.05). The recommended follow up time for observed HN was no different between CRUS and POCUS (p > 0.05). Children with worsening HN on POCUS underwent functional studies without confirmatory CRUS. Interestingly, two patients had metachronous, contralateral UPJO discovered during post-operative imaging. These were both discovered by POCUS. Nineteen (42%) patients who had attended at least one post-operative visit were eventually loss to follow-up. This occurred exclusively in those who did not have worsening ultrasound (p < 0.01). There was no difference in the loss to follow-up after POCUS (8) or CRUS (12) (p > 0.05). CONCLUSIONS POCUS performed by a urologist is an accurate assessment of HN after pyeloplasty with time and cost savings to compared to a CRUS performed by a radiologist. POCUS is not associated with any difference in rate of detection of worsening HN or rate of loss to follow up.

Abstract
A 25-year-old man with a history of left ureteropelvic junction (UPJ) obstruction that was corrected surgically at the age of 16 presented with a chief complaint of syncope. He was found to have severe hypertension with evidence of end organ damage on laboratory evaluation. His blood pressure was controlled with intravenous and oral antihypertensives with improvement in end organ dysfunction. Workup for secondary causes of hypertension implicated failed left-sided pyeloplasty with resultant hydronephrosis as the aetiology. The patient was transitioned to an oral antihypertensive regimen and discharged with urological surgery follow-up. Blood pressure control was maintained with oral antihypertensives and a low-salt diet; however, evidence of chronic kidney disease persisted. This case highlights the importance of close follow-up and adequate transition of care in patients with UPJ obstruction who transitioned to adulthood.

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.
