The impact of audiovisual information on parental anxiety levels prior to hypospadias surgery: A prospective single center cohort study.

BACKGROUND: Most parents have anxiety before a pediatric surgical procedure. Parental anxiety may impair the parents' ability to cope with new or stressful situations while their children are undergoing surgery. By effectively improving the education of parents regarding the diagnosis, treatment, and potential complications of hypospadias and surgical repair, it might be feasible to reduce their anxiety during this process. OBJECTIVE: To determine whether structured audiovisual information would reduce parents' anxiety levels compared to classic verbal information. MATERIAL AND METHODS: The diagnosis was made and, treatment options were explained, and State-Trait Anxiety Inventory Form - State Anxiety (STAI-I) forms were filled out by parents at the first consultation. In the second consultation, parents were divided into structured audio-visual-information (Group-1) and classic verbal information (Group-2) groups. Following these consultations, all parents in both groups filled out STAI-I again. Parents filled out the forms for the last time on the postoperative-14th-day and the results were compared. RESULTS: A total of 124 (51.2%) parents were informed with structured-audiovisual-informational material and 118 parents (48.8%) were informed with classic verbal information. First STAI-I scores were 57.65 ± 5.17 and 56.91 ± 5.28 for Group-1 and Group-2, respectively, and there was no difference between the groups (p = 0.709). The STAI-I scores after the second consultation were 44.82 ± 5.65 and 49.42 ± 2.81 for Group-1 and Group-2, respectively. Parental anxiety decreased in both groups following the second consultation. Notably, a statistically significant superiority was found between the groups in favor of Group-1 (p = 0.001). DISCUSSION: Parents whose children will undergo hypospadias surgery experience significant anxiety. We observed that informing patients adequately and in appropriate language using a suitable method was associated with less anxiety. Preoperative parental anxiety is influenced by several variables, including parent age, parent gender, child age, lack of knowledge, and concerns over complications or pain. Although we are unable to alter the factors of child age and parent gender, we can impact parents' concerns regarding postoperative pain and anesthesia by enhancing their comprehension of the procedure via providing them of sufficient and accurate information. CONCLUSION: Providing parents with structured audio-visual information about the preoperative and postoperative period before hypospadias surgery is associated with lower parental anxiety levels. Supplying structured audiovisual information regarding the preoperative and postoperative periods can help parents have an improved comprehension of the procedure and minimize their anxiety.

Urinary stone in infants; should vitamin D prophylaxis be stopped?

BACKGROUND: This study investigated the effect of the discontinuation of vitamin D supplementation on kidney stone formation in children under 2 years of age. METHODS: This study involved a retrospective analysis of two patient groups. The first group comprised postoperative patients who were stone-free, while the second group consisted of asymptomatic patients with kidney stones. The patients who discontinued vitamin D supplementation and those who continued were compared in terms of stone formation and stone size progression. The data collected included patient characteristics, stone size measurements, and laboratory results. RESULTS: The findings showed that the discontinuation of vitamin D supplementation was not associated with kidney stone formation or the progression of stone size in either group. For patients who were stone-free on ultrasonography 1 month after the operation, according to the 12-month ultrasonography evaluation, in the group that discontinued vitamin D, 42 (78%) patients had no stones, 6 (11%) patients had stones larger than 3 mm, and 6 (11%) patients had microlithiasis. However, in the group that continued vitamin D, 49 (72%) patients were stone-free, 10 (15%) patients had stones larger than 3 mm, and 9 (13%) patients had microlithiasis. There was no difference between the groups in terms of stone status at 12 months (p = 0.76). For patients with asymptomatic kidney stones, the initial stone sizes were similar between the groups (p = 0.74). During the 6th month of ultrasound, the changes in stone size were 1.76 ± 1.81 mm and 1.79 ± 1.75 mm for the two groups, respectively (p = 0.9). During the 12-month ultrasound measurement, the changes in stone size were 1.98 ± 2.93 mm and 2.60 ± 2.48 mm for the two groups, respectively (p = 0.09). CONCLUSIONS: We believe that more research is needed to make definitive recommendations regarding vitamin D prophylaxis in infants with kidney stones. Although the first objective of our study is not conclusively proven with the current findings, we recommend continued vitamin D prophylaxis in infants with urolithiasis.

European Association of Urology/European Society for Paediatric Urology Guidelines on Paediatric Urology: Summary of the 2024 Updates.

BACKGROUND AND OBJECTIVE: We present an overview of the 2024 updates for the European Association of Urology (EAU)/European Society for Paediatric Urology (ESPU) guidelines on paediatric urology to offer evidence-based standards for perioperative management, minimally invasive surgery (MIS), hydrocele, congenital lower urinary tract obstruction (CLUTO), trauma/emergencies, and fertility preservation. METHODS: A broad literature search was performed for each condition. Recommendations were developed and rated as strong or weak on the basis of the quality of the evidence, the benefit/harm ratio, and potential patient preferences. KEY FINDINGS AND LIMITATIONS: Recommendations for perioperative management include points related to fasting, premedication, antibiotic prophylaxis, pain control, and thromboprophylaxis in patients requiring general anaesthesia. MIS use is increasing in paediatric urology, with no major differences observed among different MIS approaches. For hydrocele, observation is the initial approach recommended. For persistent cases, treatment varies according to the type of hydrocele. CLUTO cases should be managed in tertiary centres with multidisciplinary expertise in prenatal and postnatal management. Neonatal valve ablation remains the mainstay of treatment, but associated bladder dysfunction requires continuous treatment. Among urological traumas and emergencies, renal trauma is still an important cause of morbidity and mortality. Conservative management has become the standard approach in haemodynamically stable children. Ischaemic priapism is a medical emergency and requires stepwise management. Initial management of nonischaemic priapism is conservative. Fertility preservation in prepubertal children and adolescents has become an increasingly relevant issue owing to the ever-increasing number of cancer survivors receiving gonadotoxic therapies. A major limitation is the scarcity of relevant literature. CONCLUSIONS AND CLINICAL IMPLICATIONS: This summary of the 2024 EAU/ESPU guidelines provides updated guidance for evidence-based management of some paediatric urological conditions. PATIENT SUMMARY: We provide a summary of the updated European Association of Urology/European Society for Paediatric Urology guidelines on paediatric urology. There are recommendations on steps to take before and immediately after surgery, management of hydrocele, congenital lower urinary tract obstruction, and urological trauma/emergencies, as well as preservation of fertility. Recommendations are based on a comprehensive review of recent studies.

Risk factors for recurrence in pediatric urinary stone disease.

BACKGROUND: Children's urinary system stones may develop from environmental, metabolic, anatomical, and other causes. Our objective is to determine the recurrence and prognosis, demographic, clinical, and etiological characteristics of children with urolithiasis. METHODS: Medical records of patients were evaluated retrospectively. Patients' demographic data and medical history, serum/urine biochemical and metabolic analysis, blood gas analysis, stone analysis, imaging findings, and medical/surgical treatments were recorded. RESULTS: The study included 364 patients (male 187). Median age at diagnosis was 2.83 (IQR 0.83-8.08) years. The most common complaints were urinary tract infection (23%) and urine discoloration (12%). Sixty-two percent had a family history of stone disease. At least one metabolic disorder was found in 120 (88%) of 137 patients having all metabolic analyses: hypercalciuria was found in 45%, hypocitraturia in 39%, and hyperoxaluria in 37%. Anatomical abnormalities were detected in 18% of patients. Of 58 stones analyzed, 65.5% were calcium and 20.6% were cystine stones. Stone recurrence rate was 15% (55/364). Older age (> 5 years), family history of stone disease, stone size (≥ 5 mm), and urinary system anatomical abnormalities were significantly associated with stone recurrence (p = 0.027, p = 0.031, p < 0.001, and p < 0.001, respectively). In adjusted logistic regression analysis, stone size ≥ 5 mm (OR 4.85, 95% CI 2.53-9.3), presence of urinary system anatomical abnormalities (OR 2.89, 95% CI 1.44-5.78), and family history of stone disease (OR 2.41, 95% CI 1.19-4.86) had increased recurrence rate. CONCLUSIONS: All children with urolithiasis should be evaluated for factors affecting stone recurrence. Children at higher risk of recurrence need to be followed carefully.

Update and Summary of the European Association of Urology/European Society of Paediatric Urology Paediatric Guidelines on Vesicoureteral Reflux in Children.

BACKGROUND AND OBJECTIVE: The prescriptive literature on vesicoureteral reflux (VUR) is still limited and thus the level of evidence is generally low. The aim of these guidelines is to provide a practical approach to the treatment of VUR that is based on risk analysis and selective indications for both diagnostic tests and interventions. We provide a 2023 update on the chapter on VUR in children from the European Association of Urology (EAU) and European Society for Paediatric Urology (ESPU) guidelines. METHODS: A structured literature review was performed for all relevant publications published from the last update up to March 2022. KEY FINDINGS AND LIMITATIONS: The most important updates are as follows. Bladder and bowel dysfunction (BBD) is common in toilet-trained children presenting with urinary tract infection (UTI) with or without primary VUR and increases the risk of febrile UTI and focal uptake defects on a radionuclide scan. Continuous antibiotic prophylaxis (CAP) may not be required in every VUR patient. Although the literature does not provide any reliable information on CAP duration in VUR patients, a practical approach would be to consider CAP until there is no further BBD. Recommendations for children with febrile UTI and high-grade VUR include initial medical treatment, with surgical care reserved for CAP noncompliance, breakthrough febrile UTIs despite CAP, and symptomatic VUR that persists during long-term follow-up. Comparison of laparoscopic extravesical versus transvesicoscopic ureteral reimplantation demonstrated that both are good option in terms of resolution and complication rates. Extravesical surgery is the most common approach used for robotic reimplantation, with a wide range of variations and success rates. CONCLUSIONS AND CLINICAL IMPLICATIONS: This summary of the updated 2023 EAU/ESPU guidelines provides practical considerations for the management and diagnostic evaluation of VUR in children. ADVANCING PRACTICE: For children with VUR, it is important to treat BBD if present. A practical approach regarding the duration of CAP is to consider administration until BBD resolution. PATIENT SUMMARY: We provide a summary and update of guidelines on the diagnosis and management of urinary reflux (where urine flows back up through the urinary tract) in children. Treatment of bladder and bowel dysfunction is critical, as this is common in toilet-trained children presenting with urinary tract infection.

Endoscopic dilatation/incision of primary obstructive megaureter. A systematic review. On behalf of the EAU paediatric urology guidelines panel.

INTRODUCTION: Historically, ureteral reimplantation (UR) has been the gold standard for treatment of primary obstructive megaureter (POM) with declining renal function, worsening obstruction, or recurrent urinary tract infections. In infants, open surgery with reimplantation of a grossly dilated ureter into a small bladder, can be technically challenging with significant morbidity. Therefore, less invasive endoscopic management such as dilatation or incision of the ureter-vesical junction, has emerged as an alternative to reimplantation during the last decades. OBJECTIVE: To systematically evaluate the effectivity, safety, and potential benefits of endoscopic treatment (dilatation with or without balloon or incision) of POM in comparison to UR. STUDY DESIGN: A systematic review was conducted. Randomized controlled trials (RCTs), nonrandomized comparative studies (NRSs), and single-arm case series including a minimum of 20 participants and a mean follow-up more than 12 months were eligible for inclusion. RESULTS: Of 504 articles identified, 8 articles including 338 patients were eligible for inclusion (0 RCTs, 1 NRSs, and 7 case series). Age at time of surgery was minimum 15 days to a maximum of 192 months. Indications for endoscopic treatment (ET) included patients with loss of split renal function (>10%) and worsening of hydroureteronephrosis. The studies analysed reported a success rate ranging from 35% to 97%. Success was defined as stabilization of differential renal function without further procedures. A post-operative complication rate of 23-60% was reported (mostly transient haematuria, urinary tract infections and stent migration or intolerance). In 14% of the cases salvage UR following initial ET, was performed due to relapse of symptomatic POM. CONCLUSION: Endoscopic treatment for persistent or progressive POM in children is a minimally invasive alternative to UR with a long-term modest success rate. Additionally, it can be performed within a wide age span, with equal success rate and complication rates.

Long Term Follow-Up Of Patients With Nonrefluxing Hydronephrosis.

BACKGOUND: The aim of this study is to examine the long-term prognosis of children with ureteropelvic junction obstruction-like hydronephrosis (UPJO-like HN). PATIENTS AND METHODS: The files of children with hydronephrosis (HN) were analyzed retrospectively. Patients with vesicoureteral reflux (VUR) and other genitourinary anomalies were excluded. The final status of the HN, the need for surgery, and urinary tract infection (UTI) frequency were evaluated. RESULTS: The study included 219 patients with 302 renal units (RU) with HN. Surgery rate was higher in RUs with larger kidney size and parenchymal thinning (p:<0.001 for both). Hydronephrosis resolved in 113 (40.2%) RUs, improved in 66 (23.3%), unchanged in 100 (35.5%) and worsened in 4 (1.4%). The frequency of recovery and improvement was found to be less in RUs with severe HN, large kidney size, and thin parenchyma. The UTI frequency was higher in severe HN group (12.2% vs 30.6% p:<0.001). CONCLUSIONS: Children with mild HN had an excellent prognosis. Although the majority of the patients with high-grade HN had also a good prognosis, it seems important to closely follow up patients with severe HN, increased kidney size, and accompanying parenchymal thinning. Clinicians should be aware of the increased frequency of UTIs in children with severe HN.

Functional recoverability post-pyeloplasty in children with ureteropelvic junction obstruction and poorly functioning kidneys: Systematic review.

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.

Expanding the HPSE2 Genotypic Spectrum in Urofacial Syndrome, A Disease Featuring a Peripheral Neuropathy of the Urinary Bladder.

Urofacial (also called Ochoa) syndrome (UFS) is an autosomal recessive congenital disorder of the urinary bladder featuring voiding dysfunction and a grimace upon smiling. Biallelic variants in HPSE2, coding for the secreted protein heparanase-2, are described in around half of families genetically studied. Hpse2 mutant mice have aberrant bladder nerves. We sought to expand the genotypic spectrum of UFS and make insights into its pathobiology. Sanger sequencing, next generation sequencing and microarray analysis were performed in four previously unreported families with urinary tract disease and grimacing. In one, the proband had kidney failure and was homozygous for the previously described pathogenic variant c.429T>A, p.(Tyr143*). Three other families each carried a different novel HPSE2 variant. One had homozygous triplication of exons 8 and 9; another had homozygous deletion of exon 4; and another carried a novel c.419C>G variant encoding the missense p.Pro140Arg in trans with c.1099-1G>A, a previously reported pathogenic splice variant. Expressing the missense heparanase-2 variant in vitro showed that it was secreted as normal, suggesting that 140Arg has aberrant functionality after secretion. Bladder autonomic neurons emanate from pelvic ganglia where resident neural cell bodies derive from migrating neural crest cells. We demonstrated that, in normal human embryos, neuronal precursors near the developing hindgut and lower urinary tract were positive for both heparanase-2 and leucine rich repeats and immunoglobulin like domains 2 (LRIG2). Indeed, biallelic variants of LRIG2 have been implicated in rare UFS families. The study expands the genotypic spectrum in HPSE2 in UFS and supports a developmental neuronal pathobiology.

Could urinary nerve growth factor and bladder wall thickness predict the treatment outcome of children with overactive bladder?

ABSTRACT Objective: Bladder wall thickness (BWTh) measurements and Nerve Growth Factor (NGF) /creatinine (Cr) values, as noninvasive tools, were found to predict daytime voiding problems in children with overactive bladder (OAB). The goal of this research was to examine if bladder wall thickness together with urine NGF/Cr could be a clinical utility in treatment outcome of OAB in children. Patients and Methods: A total of 60 children with OAB, (Group 1; n=40) and healthy normal controls (Group 2; n=20), aged 6-14 years old were involved in this prospective study. Children were evaluated with detailed history and physical examination, including neurologic examination, and were asked to complete a self-reported questionnaire and a 3-day bladder diary with the aid of their parents. Uroflowmetry was performed in all cases. Urinary nerve growth factor levels were measured by the ELISA and BWTh was measured trans-abdominally by one uro-radiologist specialized in pediatric ultrasonography. Urinary NGF levels were normalized by urinary creatinine levels and compared among all subgroups. Children with OAB received urotherapy as first line treatment at least for three months. 18 children refractory to urotherapy received anticholinergic therapy defined as group 3. Results: The median age of the study group was 10 (range 6 to 16). After urotherapy, 22 children had similar BWTh and NGF/Cr values compared to controls. (2.75 ± 1.15; 2.40 ± 1.00 mm; p=0.86 and 1.02 ± 0.10; 0.78 ± 0.15; p=0.12, respectively). After anticholinergic treatment, BWTh levels (2.25 ± 0.90; 2.40 ± 1.00 mm; p=0.94) and NGF/Cr values (0.95 ± 0.10; 0.78 ± 0.15; p=0.42, respectively) had no significantly difference compared to controls (Group 2). In receiver operating characteristic analysis, bladder wall thickness was found to have sensitivity of 85% and specificity of 84.2% (3,20 AUC, 913; 95 %) and NGF/Cr had sensitivity of 90% and specificity of 92.1% (1,595; AUC, 947; 95 %) in predicting treatment outcome in children with OAB. Conclusions: Bladder wall thickness measurements and NGF/Cr values, as noninvasive tools, could guide outcomes in the treatment of children with overactive bladder.

CONCLUSIONS: Bladder wall thickness measurements and NGF/Cr values, as noninvasive tools, could guide outcomes in the treatment of children with overactive bladder.

Predicting ESWL success by determination of Hounsfield unit on non-contrast CT is clinically irrelevant in children.

The necessity of determining stone density by non-contrast computerized tomography (NCCT) before extracorporeal shock wave lithotripsy (ESWL) is a controversial topic due to the radiation exposure. We aimed to investigate whether stone density is helpful in predicting the success of ESWL in pediatric patients or not. In this retrospective study, database of a single center was used to identify 232 children aged between 2 and 16 years. Patients with abnormal renal anatomy, distal obstruction, a known cystine stone disease, a previous history of an intervention regarding stone, and an insufficient follow-up period (< 3 months) were excluded from the study. A total of 209 patients were included in the study (94 with NCCT, 115 without NCCT). Groups were compared in terms of stone size, stone location, and stone-free rate at 3 months after a single ESWL session. The mean age was 6.17 ± 3.27 years and 120 (57.4%) of the patients were male and 89 (42.6%) were female. Mean stone size was 11.7 mm in NCCT group and 12.3 mm in non-NCCT group (p 0.128). The complete stone clearance rate in NCCT and non-NCCT group at 3 months after ESWL was 57.4% (54/94) and 54.7% (63/115), respectively, and there was no statistically significant difference (p 0.316). In conclusion, unnecessary NCCT use should be avoided before ESWL considering the similar success rates after ESWL and the risk of exposure to radiation.

Can lockdown and homeschooling change the outcome of urotherapy for lower urinary tract dysfunction in children?

OBJECTIVE: Lower urinary tract dysfunction (LUTD) are still important for both children and pediatric urologists. Urotherapy is recommended in LUTD treatment management. In our country, all citizens under the age of 20 were banned from going out of their homes due to Covid-19 and the homeschooling system has been adopted The aim of this study is to investigate the effect of lockdown and homeschooling on the effectiveness of urotherapy used for LUTD treatment. METHODS: 83 patients were included in the study group. Besides 306 patients were determined as the control group (pre-Covid). The patients in the study group and the control group were compared in terms of improvement in Dysfunctional voiding and incontinence scoring system (DVISS), quality of life scores, bladder diary, Bristol stool scale, and treatment responses at 3rd and 6th months. RESULTS: The study group and control group were compared in terms of DVISS, voiding frequency and incontinence in the voiding diary, quality of life score, and Bristol stool scale at admission visit and the group characteristics were similar. During the 6th month visit, the mean DVISS of the study group was found to be significantly lower (7.12 ± 3.48; 8.58 ± 4.06 respectively (p 0.002)). Daily voiding frequency was similar in the study group and the control group during the 2nd and 3rd visit. The study group's mean number of daily incontinence was significantly lower at visit 3 (0.57 ± 0.9; 0.94 ± 0.27, respectively (p 0.02).After six months of treatment, 13.3% of the study group patients had a complete response, 44.6% had a partial response, whereas 42.2% non-responders. In the control group, the response rates were as 5.9%, 39.2% and 54.9% respectively (p 0.02). CONCLUSIONS: LUTD is still very common in pediatric urology. Standard urotherapy is widely used in treatment management. According to our results, the success of standard urotherapy increases with lockdown and homeschooling. We have shown that the success of standard urotherapy can be improved by regulating environmental conditions. In terms of LUTD management, environmental conditions can be regulated to provide a better quality of life and a better cure in a more economical way.

Clinical practice in vesicoureteral reflux with respect to EAU guidelines: A multicenter study.

PURPOSE: We designed a multicenter, retrospective study to investigate the current trends in initial management of reflux with respect to European Association of Urology (EAU) Guidelines in Urology clinics of our country. MATERIALS AND METHODS: The study group consisted of 1988 renal units (RU) of 1345 patients treated surgically due to vesicoureteral reflux (VUR) (between years 2003 and 2017) in nine different institutions. Patients were divided into two groups according to time of initial treatment and also grouped according to risk factors by "EAU guidelines on VUR." RESULTS: In this series, 1426 RUs were treated initially conservatively and 562 RUs were initially treated with surgery. In initially surgically treated group, success rates of surgery decreased significantly in low and moderate risk groups after 2013 (P = .046, P = .0001, respectively), while success rates were not significantly different in high risk group (P = .46). While 26.6% of patients in low risk group were initially surgically treated before 2013, this rate has increased to 34.6% after 2013, but the difference was not statistically significant (P = .096). However, performing surgery as the initial treatment approach increased significantly in both moderate and high risk groups (P = .000 and P = .0001, respectively) after 2013. Overall success rates of endoscopic treatments and ureteroneocystostomy (UNC) operations were 65% and 92.9% before 2013 and 60% and 78.5% after 2013, respectively. Thus, the overall success rate for surgery was 72.6%. There was significant difference between success rates of UNC operations before and after 2013 (P = .000), while the difference was not significant in the injection group (P = .076). CONCLUSION: Current trends in management of reflux in our country do not yet follow the EAU guidelines on VUR in low and moderate risk groups despite these reliable and accepted guidelines were expected to influence our daily approach.

Effect of continuous antibiotic prophylaxis in children with postoperative JJ stents: A prospective randomized study.

OBJECTIVE: We aimed to investigate the effectiveness of continuous antibiotic prophylaxis (CAP) in patients with JJ stent and tried to identify the group that could specifically benefit from CAP by a prospective randomized study. METHODS: A prospective, randomized, controlled, non-blind, non-placebo study was performed in a single center.A total of 105 patients who underwent surgery with JJ stent (PNL, URS, pyeloplasty, UNC) were randomized into two groups. 53 patients in Group A received CAP and 52 patients in Group B were controlled without CAP, during the presence of a JJ stent. Patients with external stents, nephrostomy tubes, indwelling long-term urethral catheters were excluded. History of preoperative use of CAP and lower urinary tract symptoms were noted. Trimethoprim/sulfamethoxazole (TMP/SMX) was used as the initial choice of antibiotic however if there was a history of antibiotic resistance in previous urinary cultures, Nitrofurantoin was administrated. Urinary cultures were obtained before surgery and before stent extraction. JJ stents were sent to culture. Symptomatic febrile urinary tract infections with positive urine cultures (105 CFU on a clean catch or 103with urethral catheterization) were compared between groups. DISCUSSION: Our study has some limitations; the study is the single-center, we did not follow-up of patients in terms of scar, there were low number of uncircumcised patients, multiple types of surgical procedures were performed. JJ stent is a frequently used instrument in children. Unfortunately, any randomized prospective on antibiotics administration while using a JJ stent is not available in the current literature. We hope our research will contribute to the existing literature and cause a significant change in clinical practice. RESULTS: The mean age among all patients was 4.8 ± 3.9 years. The mean length of time jj stents stayed inside was 16.34 ± 6.45 days in group A and 15.29 ± 7.71 days in group B. The incidence of febrile urinary tract infections with CAP was significantly reduced (3.8% vs. 19% (p 0.015)). Multivariate regression analysis revealed that a positive history for preop febrile urinary tract infections and/or LUTS has a significantly higher association with the incidence of febrile urinary tract infecitons. CONCLUSIONS: CAP in the presence of JJ stents reduced the incidence of febrile urinary tract infections in a short period, especially in children with the previous history of febrile urinary tract infections and lower urinary tract symptoms.

The effects of primary and recurrent pediatric urological surgeries on parental anxiety levels.

INTRODUCTION: Invasive diagnostic and therapeutic procedures in pediatric urology may generally cause distress and pain in children. As a result, it may have a negative effect on adult and child behaviors. The anxiety, depression levels or distress and fear status caused by recurrent diseases or repetitive medical interventions in adult patients or the parents of pediatric patients have been investigated previously. OBJECTIVE: To the best of our knowledge, we have not found a study evaluating the effects of primary or recurrent pediatric urological operations on parental anxiety. Our main aim was to compare the effects of primary and repetitive pediatric urological surgeries on the anxiety levels of both mothers and fathers. We also aimed to investigate the effects of other factors related to parents and children on parental anxiety. DESIGN: A total of 163 patients under 14 years old who had undergone primary or recurrent pediatric urological operations and also their parents were included in a prospective, cross-sectional study. Demographic and clinical data of the patients and their parents were recorded. Before the surgeries, the Children's Fear Scale was applied to all patients over 3 years old and the State-Trait Anxiety Inventory was applied to all parents. The participants were divided into two main groups: primary surgery group (n:84) and recurrent surgery group (n:79). A subgroup analysis was performed according to surgery type (day surgery, minor surgery and major surgery). RESULTS: We found that repetitive surgeries, higher fear scores of children, parents' being younger, having low education level, not having enough information about the surgeries and presence of someone in the immediate vicinity who previously experienced the same surgery increased parental anxiety levels. Day surgeries did not affect fathers' state anxiety levels as much as minor and major surgeries, whereas mothers' state anxiety levels were higher than fathers' regardless of the surgery type. Children's fear level was not affected by child age, gender, surgery type or previous history of surgery. DISCUSSION: The majority of studies in the literature show no significant difference in terms of pain and fear levels in pediatric patients undergoing repeated diagnostic interventions but there are contradictory results about parental anxiety levels. There is also a lack of studies on the effects of recurrent surgeries. CONCLUSION: According to our findings, repetitive surgeries and presence of someone who previously experienced the same surgery are the most significant predictive factors increasing parental anxiety levels.

Concealed Penis after Circumcision: Is It Beneficial in Lowering Uropathogenic Colonization in Penile Skin and Preventing Recurrence of Febrile Urinary Tract Infections?

PURPOSE: To  discuss  whether  concealed  penis  after  circumcision  lowers  perimeatal  urethral  and  glanular  sulcus  uropathogenic  bacterial  colonization  in  healthy  boys  with  no  urinary  tract  problems  and  prevents  attacks  of  febrile  urinary  tract  infections  in  non-healthy  boys  with  defined  urinary  tract  abnormalities.  Materials and Methods:  This  case-control  study  was  conducted  in  Ibn-i  Sina  Hospital  and  retrospectively  collected  data  of   471 boys  were  analyzed.  All  patients  were  scanned  for  any  urinary  tract  abnormality  and  those  with  any  defined  abnormalities  were  classified  as  non-healthy  group. (123 patients)  Non-healthy  patients  were  divided  into  two  subgroups  as  concealed  (n:31)  and  non-concealed  (n:92)  penis  after  circumcision.  Healthy  patients  with  no  urinary  problems  were  divided  into  three  groups  as  circumcised  without  concealed  penis  (n:144),  with  concealed  penis  after  circumcision  (n:104)  and  uncircumcised  control  group  (n:100).  Bacterial  cultures  were  obtained  from  both  periurethral  meatal  and  glanular  sulcus  areas  by  adhering  strictly  to  the  rules  of  obtaining  bacterial  culture  to  avoid  false-positive  or  negative  culture  results.  Also  only  uropathogenic  bacterias  were  evaluated,  irrelevant  results  were  excluded.     Results:  Mean  age  was  similar  in  healthy  population.  Comparison  of  three  groups  showed  that  there  was  a  significant  difference  in  both  cultures.(P = .026 for periurethral meatal region, P = .039 for glanular sulcus region)  In  post  hoc  analysis,  non-concealed  group  had  a  lower  rate  of  culture  positivity  in  both  areas  compared  to  other  groups.    Mean  age  was  also  similar  in  non-healthy  population.  Mean  follow-up  period  was  18.2  months.  Patients  with  concealed  penis  after  circumcision  had  a  significantly  higher  number  of  febrile  UTI  attacks  (20 attacks in 8 patients vs 7 attacks in 5 patients)  compared  to  non-concealed  group. (P = .019)  All  febrile  UTI  attacks  except  one  in  this  group  occurred  below  the  age  of  12  months. A  total  of  10 patients  in  both  healthy  and  non-healthy  groups  had  postoperative  hemorrhage  after  circumcision  and  only  1  patient  had  a  wound  infection.          Conclusion:  Concealed  penis  after  circumcision  does  not  lower  perimeatal  urethral  and  glanular  sulcus  uropathogenic  bacterial  colonization  in  healthy  patients  and does not  protect  unhealthy  patients  from  febrile  urinary  tract  infection  attacks.  If  circumcision  is  planned,  concealed  penis  should  be  avoided  and  also  parents  should  be  informed  about  the  possible  risks  due  to  concealed  penis  before  the  procedure,  particularly  in  patients  with  urinary  tract  abnormalities.

Prospective Evaluation of Predictors of Testis Atrophy After Surgery for Testis Torsion in Children.

OBJECTIVE: To prospectively correlate pain duration, red scrotal skin, ultrasound appearance of testis, and intraoperative testis color to future testis atrophy after acute testicular torsion. METHODS: Patients 2 months-18 years old with unilateral acute scrotum were consecutively enrolled in a National Institutes of Health transcutaneous near-infrared spectroscopy study, with a subgroup analysis of the true torsion group. Presence or absence of red scrotal skin, pain duration, testicular heterogeneity on preoperative ultrasound, and intraoperative testis color based on a novel visual chart 5 minutes after detorsion were recorded. All testes underwent orchiopexy regardless of appearance. Percent volume difference between normal and torsed testicles on follow-up ultrasound was compared between patients with and without risk factors. RESULTS: Thirty of 56 patients who had surgical detorsion underwent scrotal ultrasound at a mean of 117 days after surgery. A color of black or hemorrhagic 5 minutes after detorsion, pain duration >12 hours, and heterogeneous parenchyma on preoperative ultrasound were associated with significant testis volume loss in follow-up compared with normal testis. All patients with a black or hemorrhagic testis had >80% volume loss. Erythematous scrotal skin was not significantly associated with smaller affected testis volume in follow-up. CONCLUSION: Based on the high atrophy rate, orchiectomy can be considered for testes that are black or hemorrhagic 5 minutes after detorsion. Pain duration >12 hours and parenchymal heterogeneity on preoperative ultrasound were also associated with testis atrophy. Red scrotal skin was not a reliable predictor of atrophy and should not delay exploration.
