- Abstract
Introduction: While not entirely understood, nocturnal enuresis (NE) has been considered pathophysiologically distinct from other non-neurogenic voiding disorders. We believe that a significant component of the pathology is due to bladder overactivity. Intravesical Onabotulinumtoxin A (OBTA) injections are utilized in overactive bladder management. We hypothesized that OBTA injections would be efficacious for NE management in pediatric patients with symptoms refractory to conventional therapies., Materials and Methods: A retrospective cohort analysis of patients <18-years-old with primary NE who underwent OBTA injections was performed. Injections were performed by a single surgeon at a single tertiary referral center per standardized protocol. Treatment response was defined as no improvement, greater than 50 % improvement in nightly accidents, or complete resolution of accidents. The primary outcome was treatment success, defined as greater than 50 % improvement in nightly accidents or complete resolution. Secondary outcomes included treatment response duration and complication data. Descriptive and bivariate statistics were performed as indicated. A Kaplan Meier analysis was performed to assess failure free survival following OBTA injection., Results: Fifty patients met inclusion criteria for this analysis. All patients had trialed at least one lifestyle modification, a bowel regimen, and at least two medications with symptom persistence. The median post-procedure follow-up time was 9.5 months (range 2-82). Improvement in incontinence symptoms compared to pre-operative baseline was seen in 94.0 % of patients, with 58.0 % demonstrating complete resolution of incontinence through most recent follow up. There was no difference in improvement rates or resolution rates in male vs female gender. The median failure free survival identified on Kaplan Meier analysis was 12.5 months (Figure 1) Minor post-operative complications (4 urinary tract infections; 1 retentive episode necessitating catheterization) were identified in five patients. There were no major post-operative complications., Discussion: Efficacy of OBTA injections was high, with treatment success demonstrated in 94 % of patients and failure free survival of 12.5 months. This procedure also demonstrated a favorable safety profile, with few minor post-operative complications identified. These results indicate that this procedure may be a beneficial therapeutic option for patients with NE refractory to multiple lines of conventional therapy. This study is limited by its retrospective design with short median follow up and potential for recall bias. It is strengthened by its large sample size and novelty., Conclusions: To our knowledge, this is the first analysis of the efficacy of OBTA injections for management of primary NE. A follow up clinical trial is essential to further understand this association., Competing Interests: Conflict of interest The authors have no conflicts of interest to disclose., (Copyright © 2024 Journal of Pediatric Urology Company.

- 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., Competing Interests: Conflict of interest We have no conflicts of interest to disclose., (Copyright © 2022 Journal of Pediatric Urology Company.

- Abstract
Purpose: Pediatric testicular torsion is a urological emergency that requires timely intervention. In 2015, quality metrics for testicular torsion were implemented in the U.S. News & World Report "Best Children's Hospitals" rankings. Our study examines and compares testicular salvage surgery rates before and after the institution of national quality metrics from a multi-institutional database., Materials and Methods: The Pediatric Health Information System® was surveyed for all testicular torsion encounters using ICD (International Classification of Diseases), Ninth and Tenth Revisions coding from 52 hospitals between January 2010 and December 2019. Patients <1 year and ≥18 years of age were excluded. Only hospitals that reported outcomes before and after quality scoring were included. Testicular salvage surgery was defined as patients having undergone orchiopexy without concomitant orchiectomy. Age, race, distance from hospital, household income and insurance status were compared., Results: A total of 890 patients (551 pre-metric and 339 post-metric) from 38 hospitals were included. The testicular salvage surgery rate was 12.5% higher in the post-metric cohort (70.9% versus 58.4%). Hospital compliance to testicular torsion quality metrics increased from 62% in 2015 to 98% in 2019. Mean age, race, distance to hospital, household income, insurance status and use of ultrasound were not statistically different between pre- and post-metric cohorts., Conclusions: Since the implementation of quality metrics, salvage surgery rates for testicular torsion increased to 70.9%, an improvement of 12.5% when compared to pre-metric outcomes. Patient factors were similar between the 2 groups. Multi-institutional prospective data are needed to validate this database study and evaluate overall testicular salvage rate.

- Abstract
Introduction: We describe the effect of a state mandated opioid consent on opioid utilization and multimodal pain use for major pediatric genitourinary surgeries., Methods: All patients who underwent an inpatient pediatric genitourinary surgery at the Children's Hospital of Pittsburgh between August 2015 and February 2020 were identified. Inpatient and outpatient multimodal pain control utilization were assessed. Delayed prescriptions or emergency department visits within 30 days were identified and when applicable referenced against National Surgical Quality Improvement Program data., Results: After accounting for a 6-month transition period following policy implementation, 462 major pediatric genitourinary procedures were identified. The frequency of discharge opiate prescriptions decreased from 68.4% prior to the transition period to 10.7% afterward(p<0.001). Morphine milligram equivalents per prescription decreased from 75(IQR 45-150) to 45(IQR 22.5-75)(p<0.001). The rate of delayed non-opioid analgesic prescriptions (6.6% vs 7.4%), delayed opioid prescriptions (1.5% vs 0.3%), or emergency department visits (11.8% vs 12.6%)(p = 0.809) remained unchanged. Data agreed with National Surgical Quality Improvement Program data in 98.5% of cases. After excluding one surgeon who departed after the transition period, regional block utilization did not change from 61/115(53%) to 147/320(45.9%)(p = 0.425)., Conclusions: A state mandated opioid consent safely reduced opioid utilization for most major pediatric genitourinary surgeries., Level of Evidence: Level III., Competing Interests: Declarations of Competing Interest None, (Copyright © 2021 Elsevier Inc.

- Abstract
Disorders of sex development (DSD) are a group of congenital conditions associated with anomalous development of internal and external genital organs. Ovotesticular disorder of sex development (OT-DSD) is a condition in which a child is born with both testicular tissue (that possesses variable fertility potential within seminiferous tubules) and ovarian tissue (with primordial follicles). These tissues may be co-existent in the same gonad (ovotestis) or independently in separate gonads. Here, we report the clinical case of a 21-month-old boy that we met during a humanitarian surgical mission performed at Hospital Dr. Francisco Moscoso Puello, Santo Domingo, Dominican Republic. The child was referred for management of hypospadias, cryptorchidism, and symptomatic right inguinal and umbilical hernias. With further chromosomal evaluation, the diagnosis of SRY-negative OT-DSD was made, and shared decision-making was used to determine the timing of gender assignment, reconstruction, and the child's long-term care team. OT-DSD is an uncommon condition with unclear causes. Once a DSD condition is suspected at birth, a complete investigation should be performed, encompassing a descriptive examination, a basic electrolyte and hormonal profile, genetic assessment, and pelvic ultrasound. Consultation with a multidisciplinary team is warranted, including pediatric urology or pediatric surgery with urologic training, endocrinology, genetics, psychology, pathology, and the patient's pediatrician at minimum before surgical reconstruction. It is crucial to involve the patient and their family with shared decision-making before surgery or gender assignment., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, De Jesus Escano et al.)

- Abstract
Purpose: Postoperative opioids are overprescribed in the United States. In November 2016 the State of Pennsylvania required an opioid consent for minors. Our hypothesis is that this mandate decreased postoperative opioid prescriptions in our division., Materials and Methods: All patients who received a urological outpatient or minor emergency procedure from August 2015 to August 2019 were identified. Surgeries performed within 6 months after mandate implementation were excluded to account for the transition period. Perioperative data including case type were extracted by a clinical data warehouse from preexisting fields within the health record. The frequencies of postoperative prescriptions, delayed prescriptions and emergency department encounters were assessed. A multivariable logistic regression to identify predictors of opioid prescription at discharge was performed., Results: A total of 4,349 patients were analyzed. The frequency of postsurgical opioid prescriptions decreased from 45.3% to 2.6% (p <0.001). The median morphine milligram equivalent decreased by 22.5 among children prescribed an opioid (p <0.001). Rates of an emergency department visits (3% vs 2.7%) or delayed nonopioid prescriptions (0.8% vs 1.2%) within 30 days of discharge were unchanged (p >0.05). Fewer patients received a delayed opioid prescription after mandate implementation (0.03% vs 0.5%, p <0.001). Female patients were less likely (OR 0.309, 95% CI 0.195-0.491; p <0.001) to receive opioids prior to but not after the mandate (OR 0.309, 95% CI 0.544-2.035; p=0.122). Increasing age was predictive of receiving an opioid before (OR 1.187, 95% CI 1.157-1.218; p <0.001) and after (OR 1.241, 95% CI 1.186-1.299; p <0.001) the mandate., Conclusions: A state mandated opioid consent for minors greatly reduced post-urological surgery opioid prescription rates without increasing rates of readmission or delayed prescriptions.

- 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., (Copyright © 2020 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

- Abstract
Introduction: Botulinum toxin A (BTX-A) is currently used as a fourth-line therapeutic option for interstitial cystitis/bladder pain syndrome (IC/BPS) management. The purpose of this study was to determine if BTX-A injection can mitigate pain and if injection location (i.e. trigone-including versus trigone-sparing injection template) impacts treatment efficacy and/or treatment complications profile., Materials and Methods: Female IC/BPS patients refractory to conservative management strategies were prospectively enrolled and asked to complete a baseline history and physical exam, post-void residual (PVR) urine volume determination, O'Leary Sant (OLS) questionnaire, and Pelvic Pain and Urgency/Frequency Symptom Scale (PUF) questionnaire. Participants were randomly assigned to one of two treatment groups and received either: 1) a trigone-including BTX-A injection template or 2) a trigone-sparing injection template. Following therapy, patients were examined in clinic at 30 and 90 day post-treatment with symptom re-assessment via repeat questionnaires and for evidence of post-procedural complications., Results: Compared to baseline, patients in both treatment groups experienced significant improvement in OLS and PUF scores at both 30 and 90 days post-treatment with BTX-A, regardless of which injection template was used (p < 0.05). Complications resulting from BTX-A were minimal (most commonly urinary tract infection (UTI) and urinary retention) and not significantly different between the treatment groups (p > 0.05). No distant spread of BTX-A was observed in any patient in either treatment group., Conclusions: BTX-A treatment using either a trigone-sparing or trigone-including injection template resulted in significant, but not location-dependent, improvement in IC/BPS symptom scores at 30 and 90 day points post-procedure with no significant difference in post-treatment complication profiles.

- Abstract
Objective: To characterize national trends in procedural management of renal trauma., Background: Management of renal trauma has evolved to favor a more conservative approach. For patients requiring intervention, there is a paucity of information to characterize the nature of procedural therapy administered., Methods: A retrospective cross-sectional analysis was performed using data contained within the National Trauma Data Bank. The National Trauma Data Bank is a voluntary data repository managed by the American College of Surgeons, containing data regarding trauma admissions at 747 level I to V trauma centers throughout the United States and Canada. Participants included any patient with renal trauma requiring intervention from 2002 to 2012. They were identified according to International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes, with codes 866.00 through 866.03 for blunt renal trauma, and codes 866.10 through 866.13 for penetrating trauma. Cases were separated into those requiring nephrectomy, renorrhaphy, or endovascular repair based on ICD-9 procedure code. The number of cases performed each year and yearly trends as measured by linear regression., Results: A total of 4296 cases were reported during the study period. Of these cases, 2635 involved blunt trauma and 1661 involved penetrating injury. There was a significant increase in the percentage of cases managed by endovascular means for both blunt and penetrating trauma (R = 0.92, P < 0.01; and R = 0.86, P < 0.01, respectively). This was primarily at the expense of nephrectomy, with cases showing significant decline in both groups., Conclusions: National trends for procedural management of renal trauma are toward less invasive interventions. These trends suggest favorable change towards renal preservation and decreased morbidity, potentially facilitated, in part, by improved radiographic staging and endovascular techniques, and also increased provider awareness of the safety and value of conservative management.

- Abstract
The acontractile bladder (AcB) is a urodynamic-based diagnosis wherein the bladder is unable to demonstrate any contraction during a pressure flow study. Although it is often grouped with underactive bladder, it is a unique phenomenon and should be investigated independently. The purpose of the present review was to examine the current literature on AcB regarding its pathology, diagnosis, current management guidelines, and future developments. We performed a review of the PubMed database, classifying the evidence for AcB pathology, diagnosis, treatment, and potential future treatments. Over the 67 years covered in our review period, 42 studies were identified that met our criteria. Studies were largely poor quality and mainly consisted of retrospective review or animal models. The underlying pathology of AcB is variable with both neurological and myogenic aetiologies. Treatment is largely tailored for renal preservation and reduction of infection. Although future developments may allow more functional restorative treatments, current treatments mainly focus on bladder drainage. AcB is a unique and understudied bladder phenomenon. Treatment is largely based on symptoms and presentation. While cellular therapy and neuromodulation may hold promise, further research is needed into the underlying neuro-urological pathophysiology of this disease so that we may better develop future treatments., (© 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.)

- Abstract
Purpose: Performance of minimally-invasive surgery (MIS) is increasing relative to open surgery. We sought to compare the contemporary rates of short-term complications of open versus laparoscopic renal and ureteral surgery in pediatric patients., Materials and Methods: A retrospective cross-sectional analysis of the National Surgical Quality Improvement Program Pediatrics database was performed of all cases in 2014 identified using CPT procedure codes for nephrectomy, partial nephrectomy (PN), ureteroneocystostomy (UNC), and pyeloplasty, and reviewed for postoperative complications. Univariate analysis was performed to determine 30-day complications, with comparison between open and MIS approaches. Receiver operator curve (ROC) analysis was performed to determine differences in body surface area (BSA) and age for open versus MIS., Results: Review identified 207 nephrectomies, 72 PN, 920 UNC, and 625 pyeloplasties. MIS was associated with older age and larger BSA except for cases of UNC. Apart from PN, operative durations were longer with MIS. However, only PN was associated with significantly longer length of hospital stay (LOS). There was no difference in incidence of all other 30-day complications. When evaluating BSA via ROC, the area under the curve (AUC) was found to be 0.730 and was significant. Children with a BSA greater than 0.408 m
2 were more likely to have MIS (sensitivity, 66.9%; specificity, 69.3%). Regarding age, the AUC was 0.732. Children older than 637.5 days were more likely to have MIS (sensitivity, 72.8%; specificity, 63.3%)., Conclusions: Pediatric MIS is associated with longer operative time for nephrectomy, but shorter LOS following PN. Surgical approach was not associated with difference in short-term complications., Competing Interests: CONFLICTS OF INTEREST: The authors have nothing to disclose.- Published

- Abstract
Objective: To compare opioid requirements before and after cystectomy for end-stage Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) using a statewide tracking system., Methods: Narcotic prescriptions were captured using the North Carolina Controlled Substance Reporting System for patients at a single institute undergoing cystectomy with urinary diversion (CWUD) for refractory, end-stage IC/BPS between 2010 and 2017. Values were documented for the year before and the year after surgery (excluding 30 days postoperatively to account for surgical pain) and converted to morphine equivalents (ME). Values were compared using Student t test., Results: Following CWUD, there was a mean decrease in opioid receipt per patient of 6535 ME/year (P = .321). 8/26 (31%) had not filled any opiate prescriptions for the preceding 3 months at time of manuscript writing., Conclusion: In certain patients with end-stage, refractory IC/BPS, CWUD can help reduce opioid requirements., (Copyright © 2017 Elsevier Inc.

- Abstract
3D printing is an evolving technology that enables the creation of unique organic and inorganic structures with high precision. In urology, the technology has demonstrated potential uses in both patient and clinician education as well as in clinical practice. The four major techniques used for 3D printing are inkjet printing, extrusion printing, laser sintering, and stereolithography. Each of these techniques can be applied to the production of models for education and surgical planning, prosthetic construction, and tissue bioengineering. Bioengineering is potentially the most important application of 3D printing, as the ability to produce functional organic constructs might, in the future, enable urologists to replicate and replace abnormal tissues with neo-organs, improving patient survival and quality of life.

Introduction: Reports of robot-assisted pyeloplasty have increased. However, it is unclear if this change is due to increased diagnosis of adult ureteropelvic junction obstruction, a shift in management based on presumed efficacy, a desire to maximize robot use or some combination thereof. Therefore, we acquired and analyzed data on a national scale to determine the incidence of interventions to correct ureteropelvic junction obstruction in adults and to characterize trends in procedure selection., Methods: Patients older than 18 years with ICD-9 procedure codes 55.87 (pyeloplasty) and 55.11 (endopyelotomy) were included in the study, with attention to those designated laparoscopic robotic assistance (17.42). Data were collected for the period from January 2000 through December 2012, and weighted to a national average using Nationwide Inpatient Sample guidelines., Results: A total of 47,992 pyeloplasties were identified. Pyeloplasty rates exhibited a significant increase during this period [F(1,11)=41.38, p <0.01] and endopyelotomy rates exhibited a significant decrease [F(1,11)=64.7, p <0.01]. A higher percentage of pyeloplasties were performed robotically in 2012 vs 2009 (54% vs 44%, p <0.010)., Conclusions: Rates of pyeloplasty appear to be increasing at the expense of endopyelotomy. The percentage of pyeloplasty cases performed robotically is increasing but it is unclear if this is due to superior results or a need for increased robot use.

- Abstract
Introduction: Domestically the estimated annual cost of medical malpractice is $55.6 billion. As surgical providers in a high risk subspecialty, urologists are at particularly high risk. Interventions for nephrolithiasis are especially common in practice, and understanding the risks associated with high volume procedures is critical for quality improvement and cost containment., Methods: Using the Westlaw legal database we identified all legal briefs with the search terms "medical malpractice" and "kidney stone" or "nephrolithiasis" for dates between January 2000 and December 2015. Each case was evaluated for alleged cause of malpractice, resulting injury and indemnity payments., Results: The initial search yielded 55 cases, which was decreased to 29 after exclusions. Most cases (15, 52%) were decided in favor of the defendant, while the remaining suits led to indemnity payments, including 6 cases that were settled and 8 with verdicts for the plaintiff. Of named defendants 75% were urologists. The mean settlement amount was $158,400 while the mean indemnity payment for verdicts decided in favor of the plaintiff was $124,400. The most commonly alleged breach of duty was negligent performance in surgery (15 cases), followed by negligent postoperative care (6 cases), and failure to diagnose and treat (5 cases). The most commonly claimed damage was death (13 cases)., Conclusions: Malpractice cases related to the management of nephrolithiasis most commonly involve allegations of negligent performance in surgery, negligent postoperative care, or failure to diagnose or treat. Urologists account for 75% of named defendants and should be aware of factors that increase the risk of litigation.

- Abstract
Objective: To determine the trend in surgical management of male stress urinary incontinence (SUI) in the context of the rate of radical prostatectomy (RP) as reported by a national database. Traditionally, the artificial urinary sphincter (AUS) has been the gold standard, but the male sling represents a newer and popular alternative. Refinements in prostate surgery may reduce the incidence and degree of subsequent SUI., Materials and Methods: A retrospective cross-sectional analysis was performed using the National Inpatient Survey database, which captures discharge data from inpatient and overnight admissions. Cases were identified by their International Classification of Diseases, Ninth Revision procedure codes. We queried the codes 58.93 (implantation of AUS), 59.4 (suprapubic sling operation), 59.5 (retropubic urethral suspension), and 59.6 (paraurethral suspension). We also queried 60.5 (RP) for comparison. Data were collected from January 2000 to December 2012 and weighted to a national average using National Inpatient Survey guidelines., Results: A total of 32,416 anti-incontinence operations (20,790 AUS and 11,625 sling procedures) were performed over the study period. There was a significant downward trend in the total number of incontinence procedures (F(1,11) = 6.15, P = .03). However, when stratifying the data by procedure type, only AUS placement demonstrated a significant decline (F(1,11) = 21.70, P <.01), whereas sling procedures significantly increased (F(1,11) = 12.95, P <.01). There was no significant change in the annual incidence of RP., Conclusion: Inpatient surgery for male SUI is decreasing overall. Placement of the AUS declined significantly, whereas sling placement became more common. Future study will determine the etiology of these trends., (Copyright © 2017 Elsevier Inc.

- Abstract
Objective: To analyze the trend in inpatient vs outpatient performance of anterior urethroplasty and examine outcomes using data from the National Surgical Quality Improvement Program database., Methods: A retrospective cross sectional analysis was performed using the National Surgical Quality Improvement Program database. Cases of single-stage anterior urethroplasty from 2006 to 2013 were identified using the International Classification of Diseases, Ninth Revision, procedure code 53410. Univariate analysis was performed to compare 30-day complication rates for inpatient and outpatient cases. A linear regression model was created for all years with greater than 50 reported cases., Results: A total of 326 anterior urethroplasties were reported; 222 (68.1%) were inpatient procedures, and 104 (31.9%) were outpatient procedures. The most common complication, urinary tract infection, was consistent between inpatient (2.7%) and outpatient (2.9%) procedures. The rate of wound dehiscence was significantly higher among outpatient cases (1.92% vs 0%, P = .03). There were no significant differences in the rates of wound infection, bleeding, graft failure, deep vein thrombosis, pneumonia, or sepsis. The linear regression model shows a significant increase in outpatient procedures (R
2 = 0.91) and equivalent decrease in inpatient procedures (R2 = 0.91) for the last 3 years of the study period. Resident involvement was associated with a decreased rate of reoperation (0% vs 8.3% P <.001)., Conclusion: There has been a shift in the performance of anterior urethroplasty toward outpatient management. Overall, complication rates appear low. Future research is necessary to determine how to decrease overall cost of single-stage urethroplasty without compromising quality of care., (Copyright © 2016 Elsevier Inc.

- Abstract
Purpose: Renal function following percutaneous nephrolithotomy has long been a concern to urologists, especially in the setting of multi-tract access. We determined whether the risk of renal injury after multi-tract percutaneous nephrolithotomy was greater than after a single access approach., Materials and Methods: We retrospectively reviewed the records of 307 consecutive patients treated with percutaneous nephrolithotomy from 2011 to 2012 at Wake Forest Health. Perioperative (99m)Tc-mercaptoacetyltriglycine nuclear renogram parameters along with serum creatinine values were assessed within 1 year of the procedure. Patients were stratified by single access vs multi-access (2 or more)., Results: We identified 110 cases in which renography was done before and after percutaneous nephrolithotomy. A total of 74 patients (67.3%) underwent single access percutaneous nephrolithotomy while 36 (32.7%) underwent multi-access percutaneous nephrolithotomy. Serum creatinine did not significantly differ between the 2 cohorts postoperatively (p = 0.09). There was a significant 2.28% decrease in renal function based on mercaptoacetyltriglycine nuclear renogram results after percutaneous nephrolithotomy of the affected kidney in patients with multiple accesses (p <0.01). This relationship was not observed when patients were stratified by multiple comorbidities associated with nephrolithiasis., Conclusions: Multi-access percutaneous nephrolithotomy is associated with a small reduction in the function of the targeted kidney compared to a single access approach., (Copyright © 2016 American Urological Association Education and Research, Inc.

- Abstract
Purpose: The relationship between erectile dysfunction and endothelial dysfunction has been described and is associated with adverse cardiac events. Endothelial dysfunction is believed to precede erectile dysfunction. Our objective was to characterize the prevalence of subjective erectile dysfunction, endothelial dysfunction and commonly related comorbidities in a population of men undergoing wellness screening., Materials and Methods: A total of 205 men presented for wellness screening. They underwent testing for endothelial dysfunction via peripheral arterial tonometry and completed a health screening questionnaire. Reactive hyperemia index scores were generated by peripheral arterial tonometry testing. A reactive hyperemia index score of 1.67 or less defined endothelial dysfunction. The Student t-test and Fisher exact test were performed for continuous and categorical variables, respectively. The association of endothelial dysfunction, erectile dysfunction and various comorbidities was calculated using univariate and multivariable analyses., Results: Of 205 men 47 reported subjective erectile dysfunction. Median age was 44 years old. The mean reactive hyperemia index in patients with erectile dysfunction was significantly lower than in patients without erectile dysfunction (1.63 vs 1.87, p = 0.001). Endothelial dysfunction was more common in men with than without erectile dysfunction (55% vs 36%, p = 0.027). Multivariable analysis revealed that men with erectile dysfunction and obesity were twofold more likely to have concomitant endothelial dysfunction (OR 2.45, 95% CI 1.13-4.24, p = 0.02 and OR 2.08, 95% CI 1.16-3.75, p = 0.01, respectively)., Conclusions: Among middle-aged men presenting for wellness screening erectile dysfunction and obesity independently predicted endothelial dysfunction, a known risk factor for long-term adverse cardiac events., (Copyright © 2016 American Urological Association Education and Research, Inc.

- Abstract
Our objective was to evaluate the efficacy of daily enemas for the treatment of overactive bladder (OAB) in children. This study was a prospective, controlled trial of 60 children with nonneurogenic OAB. The control patients (40) were treated with standard therapies, including timed voiding, constipation treatment with osmotic laxatives, anticholinergics, and biofeedback physical therapy, whereas the treatment patients (20) received only daily enemas and osmotic laxatives. On assessment of improvement of OAB symptoms, only 30% of the traditionally treated patients' parents reported resolution of symptoms at 3 months, whereas 85% of enema patients did. At the onset of the study, the average pediatric voiding dysfunction score of all patients was 14, whereas on follow-up, the average scores for traditionally treated patients and enema-treated patients were 12 and 4, respectively. This study demonstrated that daily enema therapy is superior to traditional methods for the treatment of OAB.

- Abstract
Background: The litigious nature of the American medical environment is a major concern for physicians, with an estimated annual cost of $10 billion., Objective: The purpose of this study is to identify causes of litigation in cases of testicular torsion and what factors contribute to verdicts or settlements resulting in indemnity payments., Methods: Publicly available jury verdict reports were retrieved from the Westlaw legal database (Thomson Reuters, New York, NY). In order to identify pertinent cases, we used the search terms "medical malpractice" and "testicular torsion" with date ranging from 2000 to 2013. Jury verdicts, depositions, and narrative summaries were evaluated for their medical basis, alleged malpractice, findings, and indemnity payment(s) (if any)., Results: Fifty-two cases were identified that were relevant to this study. Fifty-one percent of relevant cases were found in favor of the defendant physician, with the remaining 49% involving an indemnity payment (13% of which were settled). The most commonly sued medical providers were emergency physicians (48% of defendants), with urologists being second most common and making up 23% of the defendant pool. Emergency physicians were significantly more likely to make indemnity payments than urologists., Conclusion: Testicular torsion is a delicate condition and requires expertise in evaluation and treatment. When emergency physicians choose not to consult an urologist for possible torsion, they leave themselves open to litigation risk. When an urologist is involved in torsion litigation, they are rarely unsuccessful in their defense. Finally, ultrasound is no guarantee for success against litigation., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Colaco M and Evans R
- Abstract
Interstitial cystitis (IC) is a heterogeneous chronic disease of unknown etiology that impacts a very large number of women. Symptoms are highly variable: patients may suffer from pelvic pain that is exacerbated by bladder filling, and can be associated with a variety of lower urinary tract symptoms including frequency and urgency. Given the varying presentations and severities of corresponding treatment must be tailored to each specific patient. Current American Urological Association (AUA) guidelines separate the IC treatment recommendations into six tiers of increasing invasive therapies. These treatment guidelines begin with education and lifestyle modifications and progress through levels of physical, pharmacological, and ultimately surgical therapies for those that fail the less invasive therapies. The purpose of this review is to outline the recommendations for the treatment of IC and the evidence from which these recommendations arise. Furthermore, we examine the most up to date literature so that we may recognize future directions in the treatment of IC.

- Abstract
Objectives: To review the scientific and clinical literature to assess the basis for the use of biomaterials in stress urinary incontinence (SUI) and pelvic organ prolapse (POP). Pelvic floor diseases (PFDS), such as SUI and POP, are common and vexing disorders. While synthetic mesh-based repairs have long been considered an option for PFD treatment, and their efficacy established in randomised clinical trials, safety of its use has recently been called into question., Materials and Methods: Using the PubMed, MEDLINE and Medical Subject Headings (MeSH) databases, we performed a critical review of English-language publications that contained the following keywords: 'pelvic organ prolapse', 'stress urinary incontinence', 'mesh', 'biomaterial', 'collagen', 'elastin' and 'extracellular matrix'. After reviewing for relevance for mesh use in the pelvis by two independent reviewers with a third available in the case of disagreement, a total of 60 articles were included in the present review., Results: We found that many of the potential causes of PFDs are due to altered metabolism of patient extracellular matrix (specifically collagen, elastin, and their respective enzymes) and as such, repairs using native tissue may suffer from the same abnormalities leading to a subsequent lack of repair integrity. However, mesh use is not without its unique risks. Several publications have suggested that biomaterials may undergo alteration after implantation, but these findings have not been demonstrated in the normal milieu., Conclusion: While the decision for the use of synthetic mesh is scientifically sound, its benefits and risks must be discussed with the patient in an informed decision-making process., (© 2014 The Authors.

- Abstract
Introduction: Medical malpractice and prostate cancer screening are important issues in the current landscape of health care. We identified factors contributing to litigation in the diagnosis of prostate cancer., Methods: We used the Westlaw® database to search for jury verdict reports using the term medical malpractice combined with prostate cancer with dates ranging from January 2000 to December 2013. Each case was examined for trial year, patient age, prostate specific antigen at alleged breach of duty and at diagnosis, defendant specialty, alleged cause of malpractice, whether there was metastasis, the outcome of cases that went to trial or were otherwise settled, and the plaintiff award., Results: The initial search produced 256 results, which was narrowed to 106 cases. Of these cases 64.1% went to trial, including 66.2% that were decided for the defendant. The mean out of court settlement was $945,000, significantly lower than the mean plaintiff verdict award of $2.1 million (p = 0.0009). Primary care physicians (74.1%) were the most commonly named defendants, followed by urologists (19.6%). The most common cause was failure to perform an initial prostate specific antigen test (26.8%), followed by failure to follow elevated prostate specific antigen (22.3%)., Conclusions: Causes of malpractice revolved mostly around prostate specific antigen testing. Primary care physicians and urologists must continue to educate patients to minimize malpractice claims made in this setting. It will be important to follow data to see trends following recent guidelines.

- Abstract
Interstitial cystitis and bladder pain syndrome (IC/BPS) are terms used to describe a heterogeneous chronic pelvic and bladder pain disorder. Despite its significant prevalence, the disease etiology is not well understood and providing diagnosis and treatment can be challenging. In our study, published recently in the Journal of Urology (Colaco et al., 2014), we describe the use of microarrays as a tool to characterize IC/BPS and to determine if there are clinical factors that correlate with gene expression. This data-in-brief article describes the methodology for that study, including data analysis, in further detail. Deposited data can be found in the Gene Expression Omnibus (GEO) database: GSE57560.

- Abstract
Introduction: Erectile dysfunction (ED) is a common problem with significant impact on patient quality of life. Penile prosthesis implantation provides an effective treatment for ED but as an invasive procedure carries with it an increased risk of medicolegal liability., Aim: To investigate factors associated with malpractice litigation surrounding penile prosthesis implantation., Methods: The Westlaw legal database was used to perform an advanced search for case reports using the term "medical malpractice" in combination with "penile" or "penis" and "prosthesis" or "implant" with dates between the January 1990 and December 2013., Main Outcome Measures: Each report was examined for trial information including patient demographics, device model and indications, alleged breach of duty, alleged damages, progression to trial, case outcome, and plaintiff award(s)., Results: The initial search yielded 76 cases that were narrowed to 40 after exclusions. There were 23 (57.5%) cases that were found in favor of the defendant, while 17 (42.5%) cases led to indemnity payment to the plaintiff including two cases (5.0%) that were settled out of court and 15 (37.5%) favoring the plaintiff in front of a jury. The mean settlement received was $335,500 compared with the mean indemnity award of $831,050 for verdicts decided in favor of the plaintiff (P = 0.68). The most common breach of duty was error in surgical decision making, present in 20 cases (48.8%). Informed consent was an issue in 13 filings (31.7%), and postoperative infection was seen in 13 cases (31.7%). In cases that identified the type of implant used, 58.3% were malleable implants, and 41.7% were inflatable devices., Conclusions: The main issues involved in malpractice litigation for penile prosthesis implants included surgical performance, informed consent, and postoperative management. Urologists must be aware of these potential issues in order to minimize their malpractice liability., (© 2014 International Society for Sexual Medicine.)

- Abstract
Purpose: Interstitial cystitis and bladder pain syndrome are terms used to describe a heterogeneous chronic pelvic and bladder pain disorder. Despite its significant prevalence, our understanding of disease etiology is poor. We molecularly characterized interstitial cystitis/bladder pain syndrome and determined whether there are clinical factors that correlate with gene expression., Materials and Methods: Bladder biopsies from female subjects with interstitial cystitis/bladder pain syndrome and female controls without signs of the disease were collected and divided into those with normal and low anesthetized bladder capacity, respectively. Samples then underwent RNA extraction and microarray assay. Data generated by these assays were analyzed using Omics Explorer (Qlucore, Lund, Sweden), GeneSifter® Analysis Edition 4.0 and Ingenuity® Pathway Analysis to determine similarity among samples within and between groups, and measure differentially expressed transcripts unique to each phenotype., Results: A total of 16 subjects were included in study. Principal component analysis and unsupervised hierarchical clustering showed clear separation between gene expression in tissues from subjects with low compared to normal bladder capacity. Gene expression in tissue from patients with interstitial cystitis/bladder pain syndrome who had normal bladder capacity did not significantly differ from that in controls without interstitial cystitis/bladder pain syndrome. Pairwise analysis revealed that pathways related to inflammatory and immune response were most involved., Conclusions: Microarray analysis provides insight into the potential pathological condition underlying interstitial cystitis/bladder pain syndrome. This pilot study shows that patients with this disorder who have low compared to normal bladder capacity have significantly different molecular characteristics, which may reflect a difference in disease pathophysiology., (Copyright © 2014 American Urological Association Education and Research, Inc.

- Abstract
Purpose of Review: In light of all the recent controversy regarding the use of synthetic mesh for pelvic organ prolapse, we did a retrospective review of the evidence-based outcomes and complications for its use., Recent Findings: A total of 18 of the most recent studies in the last 5 years were selected. Studies selected were prospective randomized or quasi-randomized controlled trials that included surgical operations for pelvic organ prolapse for this review. Additionally, Cochrane review and meta-analysis of outcomes and complication were also analyzed. In terms of outcomes, the definition of successful surgery is currently being debated. Synthetic mesh provides superior anatomical and subjective cure rates compared with native tissue repair. Success rates varied greatly depending on the nature of prolapse and surgical approach. Furthermore, recurrence rates for mesh-based surgery are significantly lower than that for native tissue repair. The main unique complication of mesh is exposure and was reported in a mean of 11.4% of patients, with 6.8% of patients requiring surgical partial excision of mesh., Summary: Mesh significantly improves anatomical outcomes with sacrocolpopexy and vaginal repair. Mesh does create the unique complication which can be reduced with training and proper patient selection. Further development of better materials is vital rather than reverting to tissue-based repair. Ultimately, the decision to use mesh should be based upon a patient's personal goals and preferences after an informed conversation with her physician.

- Abstract
Purpose: The litigious nature of the medical-legal environment is a major concern for American physicians with an estimated cost of $10 billion. In this study we identify the causes of litigation in cases of radical prostatectomy as well as the factors that contribute to verdicts or settlements resulting in indemnity payments., Materials and Methods: Publicly available verdict reports were recorded using the Westlaw® legal database. To identify pertinent cases we used the search terms "medical malpractice" and "prostate" or "prostatectomy" with dates ranging from 2000 to 2013. Cases were evaluated for alleged cause of malpractice, resulting injury, findings and indemnity payment (if any)., Results: The database search yielded 222 cases, with 25 being relevant to radical prostatectomy. Of these cases 24.0% were settled out of court and the remaining 76.0% went to trial. Of those cases that went to trial 20.8% saw patients awarded damages. There was no significant difference in awards between verdict and settlement. Overall 36.0% of patients claimed that they did not receive proper informed consent and 16.0% claimed that the surgery was not the proper standard of care. Thirteen of the cases claimed negligence in the performance of the surgery with the bulk of these claims being the result of rectal perforation., Conclusions: The main issues that arise in radical prostatectomy malpractice litigation are those of informed consent and clinical performance. Comprehensive preoperative counseling, when combined with proper surgical technique, may minimize the impact of litigation., (Copyright © 2014 American Urological Association Education and Research, Inc.

- Abstract
Objective: Environmental tobacco smoke (ETS) is known to cause significant morbidity across a wide variety of organ systems. The purpose of this study was to examine the relationship of ETS exposure with pediatric urinary dysfunction., Patients and Methods: Participants were drawn from a university-based pediatric urology practice throughout the first half of 2011. All patients who presented with a chief complaint of urinary dysfunction were approached to participate (N = 184). Exclusion criteria eliminated all but 71 subjects. Of these, 68 subjects and their parents completed age-appropriate questionnaires on ETS exposure and symptom severity. Data were analyzed using descriptive statistics and relationship between exposure and outcome was evaluated via Spearman correlation analysis., Results: A total of 68 children with no known etiology for their urinary dysfunction were evaluated for symptom severity and ETS exposure. Participants demonstrated a significant positive correlation (rho = 0.592 for those 4-10 years; rho = 0.415 for those 11-17 years) between ETS exposure and severity of their urinary symptoms., Conclusions: These data indicate a positive relationship between ETS exposure and urinary dysfunction among children with no other obvious etiology for their symptoms. Physicians should inform parents of the potential dangers of childhood ETS exposure, including the possible relationship with urinary dysfunction., (Copyright © 2013 Journal of Pediatric Urology Company.

Bladder instillation therapy refers to the direct introduction of medication into the bladder and is a common treatment modality for patients with interstitial cystitis/bladder pain syndrome (IC/BPS) who have failed conservative and oral therapies. The current American Urological Association (AUA) recommendations list three medications as options for IC/BPS instillation therapy: dimethyl sulfoxide, heparin, and lidocaine. The purpose of this review is to examine the evidence behind the recommendations for these medications. We also examine several historical or experimental therapies that do not hold recommendations but are still used on rare occasion. Finally, we discuss our bladder instillation strategies as well as potential future research and development in intravesicular therapy.

- Abstract
Purpose: Scholarly productivity in the form of research contributions is important for appointment and promotion in academic urology. Some believe that this production may require significant funding. We evaluated the relationship between National Institutes of Health (NIH) funding, academic rank and research productivity, as measured by the h-index, an objective indicator of research impact on a field., Materials and Methods: A total of 361 faculty members from the top 20 NIH funded academic urology departments were examined for research productivity, as measured by the h-index and calculated from the Scopus database (http://www.info.sciverse.com/scopus). Research productivity was compared to individual funding totals, the terminal degree and academic rank., Results: NIH funded faculty members had statistically higher research productivity than nonfunded colleagues. Research productivity increased with increasing NIH funding. Departmental NIH funding correlated poorly with the mean department h-index. Successive academic rank was associated with increasing research productivity. Full professors had higher NIH funding awards than their junior NIH funded colleagues., Conclusions: There is an association among the h-index, NIH funding and academic rank. The h-index is a reliable method of assessing the impact of scholarly contributions toward the discourse in academic urology. It may be used as an adjunct for evaluating the scholarly productivity of academic urologists., (Copyright © 2013 American Urological Association Education and Research, Inc.

- Abstract
Objective: Dysfunctional voiding (DV) is an extremely common pediatric complaint. The goal of this study was to examine the relationship between DV and childhood temperament., Methods: Information about the voiding behaviors and temperaments of 50 children was examined using a case-control model. Caregivers were asked to fill out the Children's Behavior Questionnaire in order to rate their child on the dimensions of surgency, negative affect, and effortful control. The relationship between DV and these dimensions was then evaluated., Results: Males with DV were found to have lower effortful control than males with normal voiding habits. Females with DV did not demonstrate a difference in effortful control, but did demonstrate a higher rate of surgency., Conclusions: The results suggest that temperament does have an association with DV. These findings are in line with temperamental associations with other externalizing trouble behaviors and may inform potential treatment strategies for DV.

- Abstract
Robotic surgery is an important new tool in many surgical procedures, and training curriculums must adapt to this new technology. Robotic surgical simulators have been developed as a means of providing training without the inherent risks of actual surgery. The purpose of this study is to evaluate the construct validity of the RoSS surgical simulator by correlating simulator performance with amount of time in training and to create a performance model in which time in training is a parameter. A total of eight residents with varying amounts of training were given access to the RoSS surgical simulator and were evaluated on performance of a simulated surgical task. This data was then used to create Akaike information criteria to compare goodness of fit. Participants were also given a questionnaire as to their experience with the simulator and their feelings about the use of simulators in training. Training time and performance within the simulator were shown to have a linear relationship. Correlations were high, with R (2) values of 0.95, 0.94, and 0.86 for each of the three performance metrics. Likelihood ratios were similarly high at 4.25 × 10(9), 10,950, and 362. Participant opinion showed that residents feel that robotic training is an important part of their education and that the simulator is an effective supplement. The RoSS surgical simulator accurately corresponds to training level and is a valid evaluation tool of training experience. These findings are encouraging for the use of robotic simulators in surgical training.

- Abstract
Purpose: The National Institutes of Health, American Medical Association, and United States Department of Health and Human Services recommend that patient education materials be written at a fourth to sixth grade reading level to facilitate comprehension. We examined and compared the readability and difficulty of online patient education materials from the American Urological Association and academic urology departments in the Northeastern United States., Materials and Methods: We assessed the online patient education materials for difficulty level with 10 commonly used readability assessment tools, including the Flesch Reading Ease Score, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, Gunning Frequency of Gobbledygook, New Dale-Chall Test, Coleman-Liau index, New Fog Count, Raygor Readability Estimate, FORCAST test and Fry score., Results: Most patient education materials on the websites of these programs were written at or above the eleventh grade reading level., Conclusions: Urological online patient education materials are written above the recommended reading level. They may need to be simplified to facilitate better patient understanding of urological topics., (Copyright © 2013 American Urological Association Education and Research, Inc.

- Abstract
Background: Toilet training is an important marker of physical and psychosocial development, but the best strategy for implementing training is still unknown. The purpose of this study is to compare dysfunctional voiding outcomes for 2 common toilet training strategies: parent-oriented training and child-oriented training., Materials and Methods: This study was completed using a case-control design, with participants between the ages of 4 and 12 years. All participants were asked to complete questionnaires related to demographics and toilet training method. Results were then analyzed between cases and controls., Results: In all, 215 patients with a mean age 7.76 years participated in this study. Cases and controls showed no significant difference for demographic measures and socioeconomic status. Furthermore, there was no significant difference in dysfunctional voiding between toilet training methods., Conclusion: Toilet training method does not seem to have any long-term effect on dysfunctional voiding. As such, clinicians should advise parents that both methods are acceptable.

- Abstract
Metaplastic changes in the urothelium of the upper urinary tract are relatively infrequent. Metaplasia may present as either squamous or less often glandular differentiation. The process may be associated with chronic inflammation or associated chronic infections. There may be malignant transformation to either squamous cell carcinoma or adenocarcinoma. The demarcation of the metaplastic process in the minor calyces has not been well documented to date. We report the case of a 74-year-old female patient who presented with a history of chronic renal disease and acute pyohydronephrosis. The patient underwent a nephroureterectomy which revealed keratinizing desquamative squamous metaplasia throughout the renal pelvis and upper urinary tract with abrupt termination of metaplasia at the junction of the renal pelvis and the minor calyx (pyramidal zone). Immunohistochemical evaluation documents metaplastic urothelium stained positive for CK5, before converting sharply to simple cuboidal epithelium in the minor calyx (pyramidal zones) which stained positive CK7. At the junction of the metaplastic components and low cuboidal lined minor calyceal surfaces, the underlying stroma showed loss of ureteral muscularis mucosa with transition to renal parenchymal type stroma. We believe that this observation is unique and potentially relevant to the etiology and pathophysiology of pelviceal metaplasia.
