Parental Status among Successful Applicants to Urology Residency.

INTRODUCTION: In this study we assessed academic and demographic factors, including parental status, associated with men and women entering urology residency. METHODS: An anonymous, Internet based survey was created, asking about academic and demographic characteristics at the time of residency application. The survey was e-mailed to 1,184 urology residents and fellows on 3 occasions. E-mail addresses were obtained through the AUA (American Urological Association) website, PubMed® or familiar contacts. Subjects were excluded from analysis if they had completed training, trained outside of the United States or if they had nonworking e-mail addresses. Chi-squared testing and logistic regression analysis were performed. RESULTS: A total of 215 responses were suitable for analysis (150 men, 65 women). There were no significant differences between successful male and female applicants in age, relationship status, AOA (Alpha Omega Alpha Honor Society) membership, publication status or medical school ranking. Successful male applicants were significantly more likely to have children than female applicants at residency application (18% vs 3.1%, OR 6.91, p=0.0038). Significance persisted on multivariable analysis after adjusting for age and relationship status (OR 6.75, p=0.0185). CONCLUSIONS: Despite similar demographics and academic achievements, successful female applicants to urology residency are less likely to have children upon residency application. Given the challenges women face in childbearing later in their careers, efforts should be considered to foster an academic and professional environment that enables them to have children earlier if they so choose.

Male and female aphallia associated with severe urinary tract dysplasia.

INTRODUCTION: Aphallia is exceedingly rare (1/30 million births). Previous reports have provided limited detail on associated urinary tract findings. OBJECTIVE: We reviewed urinary tract anomalies in two boys with aphallia (patients 1 and 2) and a girl with urinary tract dysplasia, a similar external appearance and lack of corporal tissue (patient 3), also consistent with aphallia. CASE REPORTS (FIGURE): Patients 1 and 2 both had a 46XY karyotype, bilateral descended testes in well-formed scrotums, and posterior skin tags containing rudimentary urethras. Patient 1 had a focal area of urethral narrowing; a posterior bladder diverticulum, which drained a ureter; bilateral grade 5 vesicoureteral reflux, with a right partial renal duplication; and hydronephrosis of all moieties. Patient 2 had posterior urethral valves and a bladder diverticulum. Right ureterovesical junction obstruction required a tapered reimplant and later conversion to right-to-left transureteroureterostomy. Patient 3 had a 46XX karyotype and fused, well-formed labia majora. A posterior skin tag was associated with a stenotic urogenital sinus, beyond which were a vagina posteriorly and a right refluxing ureter anteriorly. The left ureter was absent, and a miniscule pouch represented a maldeveloped or absent bladder. Laparoscopy revealed ovaries and normal Müllerian structures. Bilateral renal dysplasia necessitated renal transplant and the creation of an ileocecal neobladder and Mitrofanoff channel. Corporal tissue was diminutive or absent in all. DISCUSSION: We see from these three patients that corporal tissue absence can occur in both male and female patients. We propose that the term aphallia can apply to both sexes, as it is the absence of corporal tissue that defines this condition. This is the only report to include and characterize findings in both male and female aphallia patients. Labioscrotal folds develop with a smooth appearance, and, posteriorly, a urethral orifice or Urogenital (UG) sinus with skin tag may be seen. Obstruction at the level of the urethra was common. Severe urinary tract dysplasia was seen in all, a finding not consistently seen or characterized in previous reports. CONCLUSION: In girls with severe urinary tract dysplasia and characteristic genital ambiguity, aphallia should be considered. Co-occurrence of aphallia and severe urinary tract dysplasia warrants further urinary tract imaging in all aphallia patients, including voiding cystourethrography, renal bladder ultrasound, and serum creatinine level. Urinary tract reconstruction may be performed without hampering future penile reconstruction, due to modern phallic reconstructive techniques.

Standardized education and parental awareness are lacking for testicular torsion.

INTRODUCTION: Testicular torsion leads to orchiectomy in 30-50% of cases, which may cause psychological upset and parental guilt over a potentially avertable outcome. Presentation delay is an important modifiable cause of orchiectomy; yet, families are not routinely educated about torsion or its urgency. The present study assessed parental knowledge regarding acute scrotal pain. MATERIALS AND METHODS: An anonymous survey was distributed to parents in Urology and ENT offices, asking about their children's gender and scrotal pain history, urgency of response to a child's acute scrotal pain, and familiarity with testicular torsion. RESULTS: Surveys of 479 urology and 59 ENT parents were analyzed. The results between the two were not statistically different. Among the urology parents, 34% had heard of testicular twisting/torsion, most commonly through friends, relatives or knowing someone with torsion (35%); only 17% were informed by pediatricians (Summary Figure). Parents presenting for a child's scrotal pain were significantly more likely to have heard of torsion (69%) than those presenting for other reasons (30%, OR 5.24, P < 0.0001). Only 13% of parents of boys had spoken with their children about torsion. Roughly three quarters of them would seek emergent medical attention - by day (75%) or night (82%) - for acute scrotal pain. However, urgency was no more likely among those who knew about torsion. DISCUSSION: This was the first study to assess parental knowledge of the emergent nature of acute scrotal pain in a non-urgent setting, and most closely approximating their level of knowledge at the time of pain onset. It also assessed parents' hypothetical responses to the scenario, which was markedly different than documented presentation times, highlighting a potential area for improvement in presentation times. Potential limitations included lack of respondent demographic data, potential sampling bias of a population with greater healthcare knowledge or involvement, and assessment of parents only. CONCLUSIONS: Parental knowledge of testicular torsion was lacking, suggesting both ineffective education in the well-child setting and inappropriately timed education during or after pain occurrence. Awareness was most commonly anecdotal or taught unreliably, as even familiar parents were no more likely to seek emergent attention. Therefore, standardized, effective parental education on testicular torsion and the need for prompt presentation is needed, as is improvement in the quality of information taught in the healthcare setting. Further assessment of knowledge among preadolescent and adolescent boys regarding testicular torsion is warranted. It is hopeful that pre-hospital delay may be minimized and greater rates of testicular salvageability may be achieved through these efforts.

Inpatients hypospadias care: trends and outcomes from the American nationwide inpatient sample.

PURPOSE: Hypospadias is the most common congenital penile anomaly. Information about current utilization patterns of inpatient hypospadias repair as well as complication rates remain poorly evaluated. MATERIALS AND METHODS: The Nationwide Inpatient Sample was used to identify all patients undergoing inpatient hypospadias repair between 1998 and 2010. Patient and hospital characteristics were attained and outcomes of interest included intra- and immediate postoperative complications. Utilization was evaluated temporally and also according to patient and hospital characteristics. Predictors of complications and excess length of stay were evaluated by logistic regression models. RESULTS: A weighted 10,201 patients underwent inpatient hypospadias repair between 1998 and 2010. Half were infants (52.2%), and were operated in urban and teaching hospitals. Trend analyses demonstrated a decline in incidence of inpatient hypospadias repair (estimated annual percentage change, -6.80%; range, -0.51% to -12.69%; p=0.037). Postoperative complication rate was 4.9% and most commonly wound-related. Hospital volume was inversely related to complication rates. Specifically, higher hospital volume (>31 cases annually) was the only variable associated with decreased postoperative complications. CONCLUSIONS: Inpatient hypospadias repair have substantially decreased since the late 1990's. Older age groups and presumably more complex procedures constitute most of the inpatient procedures nowadays.

Bladder ganglioneuroma in a 5-year-old girl presenting with a urinary tract infection and hematuria: case report and review of the literature.

Ganglioneuromas are rare benign tumors arising from neural crest cells of the autonomic nervous system. These tumors may rarely localize to the bladder, and few cases have been reported in the adult literature. To date, however, bladder ganglioneuromas have not been reported in the pediatric literature. We report the case of a 5-year-old girl who presented with hematuria and a urinary tract infection and on workup was found to have a large bladder mass. Transurethral resection and pathologic examination revealed the mass to be a ganglioneuroma. The case is presented followed by a brief review of the literature.

Split-cuff nipple technique of ureteral reimplantation in children with thick-walled bladders due to posterior urethral valves.

OBJECTIVE: To describe a novel technique of ureteral reimplantation in patients with thick-walled bladders, which addresses the technical challenges and high failure rates seen in this population. METHODS: From 1997 to 2012, 45 megaureters were reimplanted in 26 children aged 2-11 years. Key surgical modifications included ureteral trough creation within the detrusor, formation of a distal ureteral split-cuff nipple, reliance on transureteroureterostomy (TUU) when the bladder would not support the reimplantation of 2 ureters, performance of psoas vesicopexy, and judicious utilization of ureteral stump augmentation in patients undergoing TUU. Follow-up ranged from 1 to 12 years. RESULTS: Seven patients underwent unilateral and 4 underwent bilateral ureteral reimplantation; TUU was performed in 15. Psoas vesicopexy was performed in 22 patients. Voiding cystourethrography showed no reflux in all children who underwent vesicopexy. Reflux resolved in 6 of 8 bilaterally reimplanted ureters; 2 of 8 had improved reflux that later resolved with Deflux injection. No ureters obstructed. Hydronephrosis improved in 32 of 45 renal units and remained stable in 13. Seven patients continue to develop bacteriuria. Five have developed renal failure. CONCLUSION: In our experience, a long ureteral trough combined with a split-cuff nipple technique for reimplanting megaureters into thick-walled bladders yields improved results over conventional submucosal tunneling, effectively eliminating or improving reflux and preventing obstruction. TUU and psoas vesicopexy proved useful adjuncts in creating adequate intravesical trough length. The risk for continued bacteriuria and renal failure due to limited renal reserve, however, remain notable in this group.

The impact of hospital volume, residency, and fellowship training on perioperative outcomes after radical prostatectomy.

OBJECTIVES: Although high-volume hospitals have been associated with improved outcomes for radical prostatectomy (RP), the association of residency or fellowship teaching institutions or both and this volume-outcome relationship remains poorly described. We examine the effect of teaching status and hospital volume on perioperative RP outcomes. METHODS AND MATERIALS: Within the Nationwide Inpatient Sample, we focused on RPs performed between 2003 and 2007. We tested the rates of prolonged length of stay beyond the median of 3 days, in-hospital mortality, and intraoperative and postoperative complications, stratified according to teaching status. Multivariable logistic regression analyses further adjusted for confounding factors. RESULTS: Overall, 47,100 eligible RPs were identified. Of these, 19,193 cases were performed at non-teaching institutions, 24,006 at residency teaching institutions, and 3,901 at fellowship teaching institutions. Relative to patients treated at non-teaching institutions, patients treated at fellowship teaching institutions were healthier and more likely to hold private insurance. In multivariable analyses, patients treated at residency (OR = 0.92, P = 0.015) and fellowship (OR = 0.82, P = 0.011) teaching institutions were less likely to experience a postoperative complication than patients treated at non-teaching institutions. Patients treated at residency (OR = 0.73, P<0.001) and fellowship (OR = 0.91, P = 0.045) teaching institutions were less likely to experience a prolonged length of stay. CONCLUSIONS: More favorable postoperative complication profile and shorter length of stay should be expected at residency and fellowship teaching institutions following RP. Moreover, postoperative complication rates were lower at fellowship teaching than at residency teaching institutions, despite adjustment for potential confounders.

Radical cystectomy in the elderly: national trends and disparities in perioperative outcomes and quality of care.

INTRODUCTION: To examine national trends of radical cystectomy (RC) for urothelial carcinoma of urinary bladder in octogenarian patients and to assess the rates of adverse outcomes. MATERIALS AND METHODS: Within the Nationwide Inpatient Sample (NIS), we focused on RCs performed between 1998 and 2007. Age was stratified as <80 versus ≥80 years. Propensity-based matched analyses were used to account for treatment selection biases. Generalized linear regression analyses were fitted to predict adverse perioperative events according to age. RESULTS: Of 12,274 RC patients, 1,605 were ≥80 years (13.1%). The RC rates in octogenarians increased significantly from 9.9% in 1998 to 13.7% in 2007. Most elderly patients were treated at low-/intermediate-volume hospitals (81.7%) and nonacademic centers (60.6%). After propensity score matching, the inpatient mortality rate was higher in octogenarians (4.6 vs. 2.6%, p < 0.001). In multivariable analyses, octogenarians were at increased risk of blood transfusions (OR: 1.30) and postoperative complications (OR: 1.22). CONCLUSIONS: Most octogenarians undergoing RC are treated at low-/intermediate-volume hospitals and at nonacademic centers. The inpatient hospital mortality is about twice as high in these patients, and adverse perioperative outcomes are more frequent. Such patients may benefit from RC at high-volume and/or academic centers to maximally reduce adverse perioperative outcomes.

Complete endoscopic management of a retained bullet in the bladder.

A 25-year-old male gunshot victim presented at our institution with gross hematuria following Foley catheter insertion. Computed tomography and cystogram did not show a bladder perforation, but were notable for a left ischial fracture and the presence of a bullet within the bladder. After failed attempts at retrieving the bullet with a resectoscope and loop, as well as a cystoscope and stone crusher, a 26 French nephroscope was inserted transurethrally, and the bullet was successfully engaged and removed using a Perc NCircle (Cook Medical, Bloomington, IN) grasper. The extra-peritoneal injury was managed conservatively with catheter drainage. To our knowledge, this represents the first case of successful transurethral management of a retained intravesical bullet. Such an approach may benefit patients with retained intravesical bullets or other challenging intravesical foreign bodies and may be helpful in select circumstances to spare patients from more extensive surgeries.

History of recurrent urinary tract infection is not predictive of abnormality on voiding cystourethrogram.

PURPOSE: The American Academy of Pediatrics recently recommended against routine voiding cystourethrograms (VCUGs) in children 2 to 24 months with initial febrile UTI, raising concern for delayed diagnosis and increased risk of UTI-related renal damage from vesicoureteral reflux (VUR). We assessed factors potentially associated with higher likelihood of abnormal VCUG, including UTI recurrence, which could allow for more judicious test utilization. METHODS: We retrospectively reviewed all initial VCUGs performed at Children's Hospital of Michigan between January and June, 2010. History of recurrent UTI was ascertained by evidence of two or more prior positive cultures or history of "recurrent UTI" on VCUG requisition. Outcomes assessed included rates of VUR or any urologic abnormality on VCUG. RESULTS: Two hundred and sixty-two patients met inclusion criteria. VUR was detected in 21.3 %, urologic abnormality including VUR in 27.4 %. Degree of bladder distension, department of referring physician, study indication, positive documented urine culture, and history of recurrent UTI or UTI and other abnormality were all not associated with increased likelihood of VUR or any urologic abnormality on VCUG. CONCLUSION: VUR and VCUG abnormality are no more likely when performed after recurrent UTI or for UTI plus other abnormality. This reasons against postponing VCUG until after UTI recurrence, as positive findings are no more likely in this setting.

Radiation safety knowledge and practices among urology residents and fellows: results of a nationwide survey.

INTRODUCTION: Reliance upon fluoroscopy within urology is increasing, with urologists key in determining radiation exposure to patients, themselves, and other healthcare personnel. However, education in occupational radiation safety is nonstandardized, often lacking. Consequently, residents and practicing urologists risk overexposure. We assessed occupational radiation safety attitudes and practices of training urologists. METHODS: A confidential, anonymous, internet-based survey on workplace radiation safety practices was distributed to residents and fellows via program directors identified from the American College of Graduate Medical Education and the American Osteopathic Association. Items explored included sources of education on occupational radiation exposure, knowledge of occupational dose limits, exposure frequency, and protective item utilization. Investigators were blinded to responses. RESULTS: Overall, 165 trainees responded, almost all of whom reported at least weekly workplace radiation exposure. Compliance with body and thyroid shields was high at 99% and 73%, respectively. Almost no one used lead-lined glasses and gloves; three-quarters cited lack of availability. The principle of keeping radiation doses As Low As Reasonably Achievable (ALARA) was widely practiced (88%). However, 70% of respondents never used dosimeters, while 56% never had one issued. Only 53% felt adequately trained in radiation safety; this number was 30% among those pregnant during training. Fewer than half (46%) correctly identified the maximum acceptable annual physician exposure. Departmental education in radiation safety improved knowledge, protective practices, monitoring, and satisfaction with education in radiation exposure. CONCLUSIONS: Our findings show that protective equipment usage and occupational radiation monitoring for the training urologist are insufficient. Despite frequent exposure, resident education in radiation safety was found lacking. Efforts should be made to address these deficiencies on a local and national level.

Absence of prostatic growth in large cohort of adult female patients with congenital adrenal hyperplasia.

PURPOSE: In girls with congenital adrenal hyperplasia the degree to which excess androgen exposure leads to the development of prostatic tissue is largely uncharacterized, except in rare case reports of prostatic growth and adenocarcinoma. Such growth yields concern for future malignant degeneration. MATERIALS AND METHODS: Chart review identified 43 adult women with congenital adrenal hyperplasia who had been longitudinally followed from birth, of whom 11 were available for history and physical examination, laboratory testing for androgen metabolites, and pelvic magnetic resonance imaging. RESULTS: Periurethral thickening was noted on digital rectal examination in 1 patient with increased 17-hydroxyprogesterone and tissue analogous to prostatic tissue was impalpable in the remaining 10. Prostate specific antigen was 0.2 ng/ml in another patient with notably increased testosterone, androstenedione, dihydrotestosterone and 17-hydroxyprogesterone, and was less than 0.1 ng/ml in the remaining patients. Magnetic resonance imaging revealed an absence of definitive prostatic tissue in all 11 patients despite evidence of genitourinary masculinization in all. Of the 11 women 7 had marked androgen excess. CONCLUSIONS: Despite androgen excess and genitourinary masculinization in patients with congenital adrenal hyperplasia, as well as case reports citing evidence of prostatic tissue and adenocarcinoma in these women, our study successfully documents the absence of notable prostatic growth in these patients. A better understanding of the timing and factors involved in prostatic growth would aid in identifying the degree to which adult women with congenital adrenal hyperplasia are at risk for adverse sequelae of Skene gland growth.

National trends and disparities in the use of minimally invasive adult pyeloplasty.

PURPOSE: Minimally invasive pyeloplasty might have several advantages compared to open pyeloplasty in the management of ureteropelvic junction obstruction. Nonetheless, minimally invasive pyeloplasty appears to be underused in North America. We examined specific patient and hospital characteristics that may be associated with these disparities. MATERIALS AND METHODS: The Nationwide Inpatient Sample was used to identify a national estimate of 29,456 patients with ureteropelvic junction obstruction treated with minimally invasive pyeloplasty (laparoscopic or robotic) and open pyeloplasty between 1998 and 2009. The rates of use of minimally invasive and open pyeloplasty were assessed according to year of surgery, and patient and hospital characteristics. The determinants of minimally invasive pyeloplasty were evaluated using logistic regression models adjusted for clustering. RESULTS: Overall 15.3% of patients underwent minimally invasive pyeloplasty between 1998 and 2009. The use of minimally invasive pyeloplasty increased remarkably during the study period from 2.4% to 55.3%, a 23-fold increase. On multivariable logistic regression analysis African-American race (OR 0.584, p = 0.015) and other insurance status (including uninsured patients, OR 0.613, p = 0.013) were associated with a lower rate of minimally invasive pyeloplasty. Patients treated at teaching (OR 1.788, p = 0.003) and/or urban (OR 4.819, p <0.001) institutions were significantly more likely to undergo minimally invasive pyeloplasty. CONCLUSIONS: In the last decade there has been a dramatic increase in the use of minimally invasive pyeloplasty in the United States and in 2009 a slight majority underwent minimally invasive pyeloplasty. Nonetheless, treatment disparities exist. African-American patients with other insurance status (including those uninsured) treated at nonteaching, rural hospitals were less likely to undergo minimally invasive pyeloplasty. Efforts should be made to understand these treatment disparities and broaden the availability of minimally invasive pyeloplasty.
