RESUMO
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.

BACKGROUND/PURPOSE: Pain control is important after penile surgery, and opioid use should be minimized as able. We sought to describe our experience performing complex penile surgeries with vs without post-operative opioids. METHODS: A retrospective review of penile surgeries, including 3998 between 2009 and 2019. We identified patients <8 years who underwent outpatient penile surgery requiring either penile degloving or hypospadias repair. Patients who were or were not prescribed opioids were matched 1:1 by age and type of penile surgery. Primary outcomes of interest were pain-related encounters, delayed opioid prescription, and predictors of pain. RESULTS: 200 children were identified, 100 per group, with mean age 1.3 ± 0.8 years. 48% were penile degloving procedures, 31% hypospadias repairs with catheters, and the remaining 21% hypospadias repairs without catheters. Perioperative features were comparable between groups(p > 0.05). 59% of patients without opioids had an impromptu post-operative encounter vs 41%, and 20% had an associated pain complaint vs 9%(p = 0.026). Two patients in both groups received delayed opioid prescription(p = 1.00). The presence of a catheter (OR 2.9) and no opioid prescription (OR 2.6) were independent predictors for pain complaint. CONCLUSIONS: Patients discharged without an opioid were more likely to contact a provider postoperatively and were more likely to endorse pain complaint (number needed to treat: 9).

BACKGROUND: Testicular torsion is a surgical emergency, and time to detorsion is imperative for testicular salvage. During the COVID-19 pandemic, patients may delay emergency care due to stay-at-home orders and concern of COVID-19 exposure. OBJECTIVE: To assess whether emergency presentation for testicular torsion was delayed during the COVID-19 pandemic, and whether the rate of orchiectomy increased compared to a retrospective period. STUDY DESIGN: Patients were prospectively enrolled in a multicenter study from seven institutions in the United States and Canada. Inclusion criteria were patients two months to 18 years of age with acute testicular torsion from March through July 2020. The retrospective group included patients from January 2019 through February 2020. Statistical analysis was performed using Kruskal-Wallis tests, Chi-square tests, and logistic regression. RESULTS: A total of 221 patients were included: 84 patients in the COVID-19 cohort and 137 in the retrospective cohort. Median times from symptom onset to emergency department presentation during COVID-19 compared to the retrospective period were 17.9 h (IQR 5.5-48.0) and 7.5 h (IQR 4.0-28.0) respectively (p = 0.04). In the COVID-19 cohort, 42% of patients underwent orchiectomy compared to 29% of pre-pandemic controls (p = 0.06). During COVID-19, 46% of patients endorsed delay in presentation compared to 33% in the retrospective group (p = 0.04). DISCUSSION: We found a significantly longer time from testicular torsion symptom onset to presentation during the pandemic and a higher proportion of patients reported delaying care. Strengths of the study include the number of included patients and the multicenter prospective design during the pandemic. Limitations include a retrospective pre-pandemic comparison group. CONCLUSIONS: In a large multicenter study we found a significantly longer time from testicular torsion symptom onset to presentation during the pandemic and a significantly higher proportion of patients reported delaying care. Based on the findings of this study, more patient education is needed on the management of testicular torsion during a pandemic.

INTRODUCTION: The COVID-19 pandemic has led to an unprecedented need to re-organise and re-align priorities for all surgical specialties. Despite the current declining numbers globally, the direct effects of the pandemic on institutional practices and on personal stress and coping mechanisms remains unknown. The aims of this study were to assess the effect of the pandemic on daily scheduling and work balances, its effects on stress, and to determine compliance with guidelines and to assess whether quarantining has led to other areas of increased productivity. METHODS: A trans-Atlantic convenience sample of paediatric urologists was created in which panellists (Zoom) discussed the direct effects of the COVID-19 pandemic on individual units, as well as creating a questionnaire using a mini-Delphi method to provide current semi-quantitative data regarding practice, and adherence levels to recently published risk stratification guidelines. They also filled out a Perceived Stress Scale (PSS) questionnaire to assess contemporary pandemic stress levels. RESULTS: There was an 86% response rate from paediatric urologists. The majority of respondents reported near complete disruption to planned operations (70%), and trainee education (70%). They were also worried about the effects of altered home-lives on productivity (≤90%), as well as a lack of personal protective equipment (57%). The baseline stress rate was measured at a very high level (PSS) during the pandemic. Adherence to recent operative guidelines for urgent cases was 100%. CONCLUSION: This study represents a panel discussion of a number of practical implications for paediatric urologists, and is one of the few papers to assess more pragmatic effects and combines opinions from both sides of the Atlantic. The impact of the pandemic has been very significant for paediatric urologists and includes a decrease in the number of patients seen and operated on, decreased salary, increased self-reported stress levels, substantially increased telemedicine usage, increased free time for various activities, and good compliance with guidelines and hospital management decisions.

BACKGROUND: Indwelling ureteral stents are commonly placed in urologic surgeries where optimal urinary drainage is necessary. In the pediatric population, removing a stent without retrieval string (SWOS) requires a secondary operation and additional anesthetic exposure. Although these burdens can be mitigated through the placement of a stent with retrieval string (SWS), fears of complications may prevent widespread adoption of this practice by pediatric urologists. OBJECTIVE: The authors sought to assess the differential cost of removing SWS and SWOS. It was hypothesized that costs associated with removing SWS are significantly lower than those associated with removing SWOS, without increasing complications. STUDY DESIGN: A retrospective chart review was performed on pediatric patients undergoing common urologic surgeries with concurrent stent placement at a single tertiary referral center. Charges and healthcare costs surrounding the removal of ureteral stents were evaluated using the institution-specific ratio of cost to charges, by estimating lost wages, and by exploring differences in poststent healthcare-related events that incur additional cost. RESULTS: A total of 109 patients with a median age of 5 years (range: 6 months-20 years) were reviewed. A total of 29 patients had SWS, and 80 had SWOS. The theoretical cost of SWS removal in clinic was $400.48 compared with $2290.86 ± $119.30 for operative removal of SWOS, with mean difference of $1890.38 (P < 0.01). The mean stent duration of SWOS was 34.0 ± 13.2 days vs. 10.1 ± 4.9 days for SWS (P < 0.01). Subgroup analysis of the ureteral reconstruction group showed no difference in any complications (35% vs 27%, respectively), early dislodgment (7% vs 7%, respectively) or costly healthcare utilization (23% vs 20%, respectively) among patients with SWOS compared with those with SWS. In SWS group with early dislodgment, neither required a secondary procedure. DISCUSSION: With rising healthcare expenditures, physicians must be able to provide cost-effective treatment while not compromising safety or outcomes. Unlike prior analyses of cost related to the type of the stent used, the present study specifically reviewed costs of removing SWS versus SWOS and evaluated rates of costly complications. The study findings provide a preliminary basis for advocating the more economical use of SWS when indicated. Lack of power and heterogeneity of the groups need to be addressed in future analyses with larger, matched cohorts. CONCLUSION: Removal of SWS is more cost-effective than that of SWOS while maintaining similar safety outcomes and should be considered in certain pediatric urology cases to decrease healthcare cost. SWS should be preferred for uncomplicated ureteroscopy, but benefits are less certain in ureteral reconstruction; further studies are needed.

PURPOSE: We assessed the impact of a 2-phase Plan-Do-Study-Act cycle to decrease opioid prescriptions following pediatric urological surgery. MATERIALS AND METHODS: Parents of children undergoing outpatient urological procedures were given questionnaires to assess opioid dosing and pain scores using the Parents' Postoperative Pain Measure scale. Age, procedure and opioid prescription data were recorded, as well as volume of medication administered. During the first phase of data collection children received an opioid prescription for 10 doses. In the second phase opioid prescriptions were reduced by 50%. Nonparametric tests and Fisher exact test were used for analysis. RESULTS: Of 250 eligible children 98 (39%) with a median age of 3.0 years (IQR 7.0) participated. In the 81 patients prescribed opioids a median of 2 doses (IQR 3.6) were used in the preintervention and postintervention groups (p = 0.68). Using nonparametric statistical testing, no significant differences were found between pain scores in the 5-dose group (31 patients) and the 10-dose group (24 patients; p = 0.05 for day 1, p = 0.07 for day 2, p = 0.06 for day 3). There was no association between age and percent opioid used (p = 0.83). There were no significant differences in median pain scores or median doses among procedure types. CONCLUSIONS: In outpatient pediatric surgical practice opioid prescriptions can be decreased without increasing pain scores. Physician prescribing practices may contribute more to opioid consumption than actual pain patterns.

Hydronephrosis discovered during prenatal ultrasound will often resolve spontaneously; however, it should be evaluated in the postnatal period in a manner commensurate with its risk of renal injury. Early intervention is appropriate in cases of bladder outlet obstruction or the severely obstructed solitary kidney. In most other cases, it is both safe and reasonable to allow the possibility of spontaneous improvement with the intensity of follow-up based on the severity of the hydronephrosis. Clinical decision making should be a shared process between families and caregivers.

INTRODUCTION/OBJECTIVE: Modern radiographic advances have allowed for detailed and accurate imaging of not only urologic anatomy but also urologic function. The art of observational inference of subtle anatomic features and function from a static radiograph is being traded for new, more precise, and more expensive modalities. While the superiority of these methods cannot be denied, the total information provided in simpler tests should not be ignored. The relationship between high grade vesicoureteral reflux with the dilated calyces arranged cephalad to a dilated funnel-shaped renal pelvis on VCUG and reduced differential renal function has not been previously described, but has been anecdotally designated a "flowerpot" sign by our clinicians. We hypothesize that the appearance of a "flowerpot" kidney as described herein is an indicator of poor renal function in the setting of high grade VUR. STUDY DESIGN: IRB approval was obtained and 315 patients were identified from system-wide VCUG reports from 2004-2012 with diagnosed "high grade" or "severe" vesicoureteral reflux. Inclusion into the study required grade IV or V VUR on initial VCUG and an initial radionuclide study for determination of differential function. Patients with a solitary kidney, posterior urethral valve, multicystic dysplastic kidney, renal ectopia, or duplex collecting systems were excluded. Grade of reflux, angle of the inferior-superior calyceal axis relative to the lumbar spine, and differential uptake were recorded along with presence of the new "flowerpot" sign. Variables were analyzed using the Mann-Whitney U test to determine statistical significance. RESULTS: Fifty seven patients met inclusion criteria with 11 being designated as "flowerpot" kidneys. These "flowerpot" kidneys could be objectively differentiated from other kidneys with grade IV and/or grade V VUR both by inferior-superior calyceal axis (median angle, 52° [37-66] vs. 13° [2-37], respectively p < 0.001) and by differential renal uptake (median, 23% [5-49] vs. 45% [15-81], respectively p < 0.001). Likewise, there was no difference between either calyceal axis (median angle, 13° [3-20] vs. 13° [2-37]) or differential function (median, 48% [24-81] vs. 40% [15-66], p = 0.129) when comparing kidneys with grade IV and grade V VUR, respectively, that did not demonstrate the "flowerpot" sign. DISCUSSION/CONCLUSION: Grading of VUR is used to provide a common language for scientific discussion and determine prognosis for children with similar attributes. The dysmorphic calyceal system in the "flowerpot" kidneys supports the theory of abnormal renal blastema induction associated with abnormal differentiation of the ureteral bud. Even in the absence of urinary tract infections and/or pyelonephritis, renal abnormalities and decreased differential function can be observed on renal scintigraphy. This study also confirms the male predominance and functional similarities between grade 4 and 5 refluxing renal units. Recognizing this is a limited observational study based on imaging alone, the "flowerpot" sign is an indicator of the most severe form of grade 5 VUR but is only one factor in predicting long term overall renal prognosis. However, 14% (8/57) of our cohort had a relative uptake of less than 20% with 5 of these exhibiting the "flowerpot" sign. The "flowerpot" sign on VCUG can be used as indirect evidence of poor differential renal function and, therefore, useful in guiding parental expectations prior to formal functional imaging.

INTRODUCTION: Currently, the surgical treatment of infected penile prostheses is complete removal and either immediate salvage procedure, which carries a significant infection risk, or delayed implantation. With delayed implantation the risk of infection is lower, but the patient loses penile length and width due to corporal fibrosis. AIM: We present our experience with the use of a novel temporary synthetic high purity calcium sulfate (SHPCaSO4) component that acts as a "spacer" at the time of removal of an infected prosthesis while providing constant delivery of local antibiotic elution to the infected area. MAIN OUTCOME MEASURES: Demonstrate that the use of a novel material, SHPCaSO4, can be an innovative way to bridge the gap between removal of an infected penile implant and delayed reimplantation. METHODS: Two patients (Patient A and B) presented with pain and erythema and were found to have infected malleable penile prosthesis. Both underwent removal of all infected components, and sent for tissue culture. The SHPCaSO4 was mixed with vancomycin and tobramycin, allowed to set up for 5 minutes, and then injected into the corporal space followed by closure with 2-0 Vicryl sutures. The injected SHPCaSO4 was palpable in the penile shaft both proximally and distally, as an "intracorporal casts." RESULTS: Patients denied pain postoperatively. Delayed implantation occurred at 6 weeks for patient A. This went uneventful and a new three-piece inflatable implant was inserted. Patient B underwent salvage placement of right malleable implant at 15 weeks, and here significant corporal fibrosis was encountered. Patients have had no infection since their delayed implantation (mean follow-up 4 months). CONCLUSIONS: Data in reference to SHPCaSO4 shows that this product dissolves in approximately 4-6 weeks. This may account for the difference in the ease of delayed implantation between the two patients. Further investigation is warranted.

INTRODUCTION: African American men have a higher rate of prostate cancer mortality compared with their Caucasian American counterparts. However, it remains unclear as to whether such differences are due to biologic or socioeconomic influences. This study sought to determine if there are differences in demographic and clinical characteristics between African American and Caucasian American men in a modern cohort undergoing extended biopsy approach, and evaluated the subsequent choice of therapy in patients diagnosed with prostate cancer. METHODS: A retrospective review was performed from a consecutive series of 500 men undergoing prostate biopsy at our institution between 2003 and 2005. All patients underwent a contemporary 10-12 biopsy scheme. Demographic, clinical, and pathologic variables as well as treatment choice (those with positive biopsy) were stratified and evaluated with regard to race-African American, Caucasian American, and other (Hispanic, Asian, American Indian). RESULTS: 65% were Caucasian American, 29% African American, and 7% other. The overall positive biopsy rate was 44%. African American men were significantly younger than Caucasian American but were not younger than "other" (61.6 vs. 64.3 vs. 61.5 years). No differences were observed with regard to prostate specific antigen density (PSAD), prostate volume, or rate of abnormal digital rectal exam (DRE). The positive biopsy rate was not different between Caucasian American and African American (46% vs. 46%), but significantly lower in other men (16%). These differences were maintained on odds ratio modeling, including age-adjusted and multivariate models. Of the 223 men with positive biopsies, information on treatment choice demonstrated that African American men had a significantly higher rate of choice of XRT (OR = 2.12) and rate of avoidance of surgery (OR = 0.35) than Caucasian American men. CONCLUSIONS: In men undergoing prostate biopsy using an extended (10-12 core) biopsy scheme, no differences were observed with regard to positive biopsy rate or other clinical or biochemical parameters [except for age and prostate specific antigen (PSA) level] between African American and Caucasian American men. Of those with a positive biopsy, African American men were more likely to avoid surgery and choose XRT in our population.

PURPOSE: The effect of obesity on prostate cancer detection and behavior remains uncertain. We evaluated the impact of obesity, as measured by body mass index, in a case series of 500 consecutive men who underwent a modern 10 to 12 core biopsy approach. MATERIALS AND METHODS: We retrospectively reviewed the records of a consecutive series of 500 men who underwent transrectal ultrasound guided prostate biopsy using a 10 to 12 core biopsy scheme. Variables, including patient age, prostate specific antigen, prostate specific antigen density, digital rectal examination findings, transrectal ultrasound prostate volume and biopsy outcome, including grade, were compared to anthropometric measures, including body mass index. RESULTS: Of the men 26% were obese according to body mass index (greater than 30 kg/m(2)). A total of 223 men (45%) had a positive biopsy. Obese men were younger (62.0 vs 63.8 years), had a larger prostate (57.7 vs 47.8 cc) and were less likely to have any abnormality on digital rectal examination (19.6% vs 30.8%). Obese men were also less likely to have a positive biopsy based on chi-square analysis (38.8% vs 46.2%). On statistical modeling for the OR in nonobese vs obese men there was a trend toward lower detection based on crude and age adjusted ORs but not on multivariate OR controlling for age, prostate specific antigen and prostate volume. In addition, when examining for high grade disease (Gleason 4 + 3 or greater), no differences were observed on OR modeling. In men with negative biopsies those who were obese vs nonobese had a larger prostate volume and trended toward a higher median prostate specific antigen and age. These differences and trends were not observed in obese men with positive biopsies. CONCLUSIONS: Of men undergoing prostate biopsy using a modern extended biopsy scheme obese men were younger, had a larger prostate and were less likely to have abnormal digital rectal examinations. Although some trends toward a lower detection rate in obese men were observed, such differences were not observed on multivariate analysis, nor were any differences observed in the incidence of higher grade tumors, thus questioning the effect of obesity on prostate cancer detection and behavior in our cases series.
