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.

The role of circumcision in preventing urinary tract infections in children with antenatal hydronephrosis: Systematic review and meta-analysis. J Pediatr Urol 2023; 19:766-777. [PMID: 37563014 DOI: 10.1016/j.jpurol.2023.07.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 07/20/2023] [Accepted: 07/24/2023] [Indexed: 08/12/2023]
Abstract
INTRODUCTION Circumcision has been reported to reduce the risk of urinary tract infections (UTIs) in boys with antenatal hydronephrosis (HN). Our aim was to compare the incidence of UTIs in circumcised vs. uncircumcised boys with antenatal HN by conducting a systematic review and meta-analysis. STUDY DESIGN A comprehensive search was performed until December 2022. Comparative studies were evaluated according to Cochrane collaboration recommendations. Assessed measures included: UTIs, continuous antibiotic prophylaxis (CAP) use, renal outcomes, and circumcision complications. Odds ratios (OR) and mean difference with 95% confidence interval (CI) were extrapolated from available data. Random-effects meta-analysis were performed. RESULTS Twenty-three studies describing 9093 boys with antenatal HN were identified, including 4677 uncircumcised and 4416 circumcised boys. Overall effect estimates demonstrate that circumcised boys have significantly reduced odds of developing any UTI [OR 0.26, 95%CI 0.21, 0.32; p < 0.001]]. In addition, there a significantly reduced odds of developing UTI when circumcised and on CAP [OR 0.19, 95% CI 0.13, 0.30; p < 0.001]. When stratifying by etiology, circumcision reduced the odds of UTI in boys with isolated HN [OR 0.33, 95% CI 0.16, 0.68; p = 0.003], vesicoureteral reflux [OR 0.23, 95% CI 0.13, 0.42; P < 0.00001], or with posterior urethral valves [OR 0.29, 95% CI 0.13, 0.64; p = 0.002]. DISCUSSION Circumcision reduces the incidence of UTIs in boys with antenatal HN. This review is limited by the varied definitions of UTIs and inconsistent reporting on HN etiology, renal outcomes, and circumcision complications. CONCLUSIONS Circumcision should be considered in boys with antenatal HN to prevent the risk of developing UTI. Further research is warranted to individualize the prophylactic role of circumcision for patients with HN.

Ureteral stent extraction strings in children: Stratifying the risk of post operative urinary tract infection. J Pediatr Urol 2023; 19:515.e1-515.e5. [PMID: 37321933 DOI: 10.1016/j.jpurol.2023.05.017] [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: 01/16/2023] [Revised: 05/01/2023] [Accepted: 05/27/2023] [Indexed: 06/17/2023]
Abstract
INTRODUCTION Ureteral stents facilitate recovery and avoid external drains in pediatric ureteral reconstruction. Extraction strings avoid the need for a secondary cystoscopy and anesthetic. Due to concerns regarding febrile UTIs in children with extraction strings, we retrospectively assessed the relative risk of UTI in children with extraction strings. OBJECTIVE Our hypothesis was that stents with extraction strings do not increase the risk of UTI after pediatric ureteral reconstruction. METHODS Records of all children undergoing pyeloplasty and ureteroureterostomy (UU) from 2014 to 2021 were reviewed. The incidences of UTI, fever, and hospitalization were recorded. RESULTS 245 patients mean age 6.4 years (163M:82F) underwent pyeloplasty (n = 221) or UU (n = 24). 42% (n = 103) received prophylaxis. Of these, 15% developed UTI versus 5% of those not receiving prophylaxis (p < 0.05). 42 females had prior history of UTI, compared to 20 males (p < 0.05). 49 patients had an extraction string. Stents with extraction strings were removed on average 0.6 months post-op while others underwent cystoscopic removal on average 1.26 months post-op (p < 0.05). 9 (18.4%) required hospitalization for febrile UTI while the stent with extraction string was in place, while only 13 (6.6%) of those without extraction string did (p < 0.02). Of the 9 children with a febrile UTI in the extraction string group, 6 had history of prior UTI (46.1%), compared to only 3 (8.3%) without a prior UTI (p < 0.05). With no prior UTI, there was no difference in UTI risk between those with (3, 8.3%) and without (8, 6.4%) extraction string (p = 0.71). Females with prior UTI and extraction string were more likely to develop UTI than those with prior UTI and no extraction string (p = 0.01). There were not enough males with history of UTI to analyze alone. There were 5 (10%) stent dislodgements in the extraction string group, 2 required further intervention with cystoscopy or percutaneous drainage. DISCUSSION Extraction strings provide the assurance of drainage while avoiding the need for a second general anesthetic procedure. There is not an increased risk of UTI with extraction string in those without prior history of UTI, but we no longer routinely leave extraction strings if there is history of UTI. CONCLUSION Children, particularly females, with prior history of UTI have a significantly increased risk of febrile UTIs associated with the use of extraction strings. Prophylaxis does not seem to reduce this risk. Patients with no prior UTI had no higher risk of UTI with extraction string use for pyeloplasty or UU.

Abstract
Background: Urinary tract infection (UTI) represents one of the most common infectious diseases and a major cause of antibiotic prescription in children. To prevent recurrent infections and long-term complications, low-dose continuous antibiotic prophylaxis (CAP) has been used. However, the efficacy of CAP is controversial. The aim of this document was to develop updated guidelines on the efficacy and safety of CAP to prevent pediatric UTIs. Methods: A panel of experts on pediatric infectious diseases, pediatric nephrology, pediatric urology, and primary care was asked clinical questions concerning the role of CAP in preventing UTIs in children. Overall, 15 clinical questions were addressed, and the search strategy included accessing electronic databases and a manual search of gray literature published in the last 25 years. After data extraction and narrative synthesis of results, recommendations were developed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Results: The use of CAP is not recommended in children with a previous UTI, with recurrent UTIs, with vesicoureteral reflux (VUR) of any grade, with isolated hydronephrosis, and with neurogenic bladder. CAP is suggested in children with significant obstructive uropathies until surgical correction. Close surveillance based on early diagnosis of UTI episodes and prompt antibiotic therapy is proposed for conditions in which CAP is not recommended. Conclusions: Our systematic review shows that CAP plays a limited role in preventing recurrences of UTI in children and has no effect on its complications. On the other hand, the emergence of new antimicrobial resistances is a proven risk.

Abstract
INTRODUCTION Urinary tract infection (UTI) is more prevalent in boys with antenatal hydronephrosis (ANH). Circumcision is known to lessen the risk of UTI. This study was performed to examine the associations between circumcision and UTI among patients with ANH. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards were followed for conducting this systematic review and meta-analysis. PubMed, ScienceDirect, EMBASE, and Cochrane Library databases were searched through August 4th, 2022 to identify eligible studies. The risk of bias was measured using the Newcastle-Ottawa Scale (NOS). Review manager 5.4 was used for all analysis. RESULTS A total of 21 studies involving 8,968 patients with ANH were included in the meta-analysis. The incidences of UTI were 18.1% in the uncircumcised group and 4.9% in the circumcised group. From analysis, circumcision had significant protective effect against UTI with pooled OR of 0.28 (95% CI 0.23-0.32). The significant protective effects were also found in subgroup analysis of hydronephrosis etiology, including vesicoureteral reflux (pooled OR of 0.24; 95% CI 0.17-0.32), obstructive hydronephrosis (pooled OR of 0.34; 95% CI 0.21-0.53), and posterior urethral valve (pooled OR of 0.28; 95% CI 0.16-0.52). CONCLUSION Our meta-analysis showed that circumcision was associated with a decreased incidence of UTI in children with ANH. This benefit was consistent irrespective of the underlying cause of hydronephrosis.

Retrograde stent with external string for pediatric robotic pyeloplasty: does it reduce cost and complications? J Robot Surg 2023; 17:185-189. [PMID: 35488080 DOI: 10.1007/s11701-022-01411-y] [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: 02/03/2022] [Accepted: 03/27/2022] [Indexed: 10/18/2022]
Abstract
Robotic-assisted pyeloplasty (RAP) is a mainstay in the treatment of ureteropelvic junction obstruction (UPJO) in children. At our institution, to limit planned operating rooms visits we have placed a ureteral stent with an external string (SWES) immediately prior to RAP. In this study, we sought to quantify the operative time, complications, and costs associated with this approach compared to the traditional approach, requiring subsequent stent removal in the operating room. We hypothesized the SWES cohort would have decreased cost, yet with similar operative time and complications. We retrospectively collected all RAPs performed at our institution using the SWES approach (Aug 2012-July 2017). We excluded those with a redo pyeloplasty, and/or a percutaneous nephrostomy tube for post-operative drainage. We collected 30-day costs linked to the patients' MRN using the Pediatric Health Information System (PHIS) database. We compared 30-day healthare costs for all patients following RAP. We compared our SWES group to a national cohort of all pediatric RAP during the same time period. Lastly, we sent an anonymous, electronic survey to urologists of all PHIS institutions to identify the predominant postoperative drainage, nationally. Within our institution, we reviewed all those treated with SWES (n = 85) (Table 1). The median 30-day cost was $10,548 among those with SWES (Table 2). This was significantly less than the overall, national cohort of all pediatric RAP during the same period ($14,119, p < 0.001). There was a 15.5 % rate of unplanned return to the hospital in the SWES group. Of those unplanned returns, 8.2 % (7/85) had unplanned return for a procedure (3 for unplanned stent removal, 2 for nephrostomy tube for persistent obstruction, 1 for omental hernia, and 1 for stent replacement). With a 42.5 % (37/87) response rate, our nationwide survey found 84.6 % primarily leave stents WITHOUT a string, 7.7 % left nephrostomy tubes, and 7.7 % stents with strings. During pediatric RAP, placement of a SWES takes little time, carries a risk of unplanned visit to the operating room, saves the patient a certain, second anesthetic for stent removal, and amounts to a cost savings of approximately 25 %.

Febrile urinary tract infection after Double-J stent removal is associated with restenosis after laparoscopic pyeloplasty: A propensity score matched analysis of 503 children. J Pediatr Urol 2022; 19:200.e1-200.e7. [PMID: 36599720 DOI: 10.1016/j.jpurol.2022.12.008] [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: 08/26/2022] [Revised: 12/02/2022] [Accepted: 12/17/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE To analyze the association between the febrile urinary tract infection (fUTI) after Double-J (DJ) stents removal and restenosis after laparoscopic pyeloplasty (LP). STUDY DESIGN We retrospectively reviewed the clinical data of patients who were treated with transperitoneal LP for ureteropelvic junction obstruction from 2016 to 2020. Patients were divided into two groups according to whether they developed fUTI after DJ stent removal within 48 h. The 1:3 Propensity Score Matched (PSM) method was used to balance confounding variables. RESULTS 503 patients were included in the study. 28 (5.57%) patients developed fUTI after DJ stent removal. Compared with the non-fUTI group, age was younger, and weight was lower (P < 0.05) in the fUTI group. Restenosis occurred in 11 (2.2%) patients, of which six patients developed fUTI after DJ stent removal. The revision surgery rate in the fUTI group was significantly higher than in the non-fUTI group (21.4% vs. 1.1%, P < 0.01). After PSM, the results remained consistent. For 492 patients without restenosis, 22 patients developed fUTI. Compared with the non-fUTI group, the larger anteroposterior diameter (APD) and higher APD/cortical thickness (P/C) ratio were observed in the fUTI group at three months and six months postoperatively (P < 0.05), but the difference vanished at 12 months and 24 months after surgery (Figure). DISCUSSION FUTI after DJ stent removal is not uncommon after LP, and surgeons are often concerned about the possibility of restenosis. In the present study, although our results demonstrated a significant association between them, restenosis patients comprise only about 20% of fUTI patients. Based on our clinical observations, fUTI is often developed in children from 1 to 6 years of age, and the younger patients may be afraid of voiding because of the postoperative pain after DJ stent removal. Besides, intraoperative manipulation of DJ stent removal may lead to transient edema in the anastomotic site, causing the fUTI. For patients who develop fUTI after DJ stent removal but without persistent symptoms, the transient worsening of hydronephrosis during the early postoperative period may not impact long-term outcomes (As shown in Figure). Additional follow-up is needed to prevent the deterioration of renal function. CONCLUSIONS Our result demonstrated that fUTI after DJ stent removal is associated with restenosis after LP. For fUTI patients without restenosis, APD and P/C ratio exhibited transient worsening at three months and six months postoperatively, decreasing gradually during follow-up. Patients who develop fUTI after DJ stent removal should be monitored.

Abstract
OBJECTIVES Ureteral stents are commonly used during pyeloplasty to ensure drainage and anastomotic healing. Antibiotic prophylaxis is often used due to concerns for urinary tract infection (UTI). Although many surgeons prescribe prophylactic antibiotics following pyeloplasty, practices vary widely due to lack of clear evidence-based guidelines. We hypothesize that the rate of stent UTI does not significantly vary between children who receive antibiotics and those who do not. METHODS We reviewed the medical records of 741 patients undergoing pyeloplasty between January 2010 and July 2018 across seven institutions. Exclusion criteria were: age older than 22 years, no stent placed, externalized stents used, and incomplete records. Surgical approach, age, antibiotic use, stent duration, Foley duration, and urine culture results were recorded. Patients were categorized into two groups, those younger than four years of age and those four years and older as proxy for likely diaper use. Univariate logistic regression was conducted to identify variables associated with UTI. Multivariable backward stepwise logistic regression was used to identify the best model with Akaike information criterion as model selection criteria. The selected model was used to calculate odds ratios and 95% confidence intervals summarizing the association between prophylactic antibiotics and stent UTI while controlling for age, gender, and intra-operative urine cultures. RESULTS 672 patients were included; 338 received antibiotic prophylaxis and 334 did not. These groups differed in mean age (3.91 vs. 6.91 years, P < .001), mean stent duration (38.5 vs. 35.32 days, P < .001), and surgical approach (53.25% vs. 32.04% open vs. laparoscopic, P < .001). The incidence of stent UTI was low overall (7.59%) and similar in both groups: 31/338 (9.17%) in the prophylaxis group and 20/334 (5.99%) in the non-prophylaxis group (P = .119). Although female gender, likely diaper use, and positive intra-operative urine culture were each associated with significantly higher odds of stent UTI, prophylactic antibiotic use was not associated with significant reduction in stent UTI in any of these groups. Surgical approach, stent duration, and Foley duration were not associated with stent UTI. CONCLUSION Incidence of stent UTI is low overall following pyeloplasty. Prophylactic antibiotics are not associated with lower rates of stent UTI following pyeloplasty even after controlling for risk factors of female gender, likely diaper use, and positive intra-operative urine culture. Routine administration of prophylactic antibiotics after pyeloplasty does not appear to be beneficial, and may be best reserved for those with multiple risk factors for UTI.
