Characterizing digital access in pediatric urology.

BACKGROUND: Virtual medicine has the potential to improve access for underserved populations by facilitating timely remote evaluation. However, challenges in the real-world implementation of this technology may paradoxically exacerbate health disparities. We sought to characterize families' digital access and how social determinants of health may impact virtual medicine access within pediatric urology. We hypothesized that disadvantaged socioeconomic status would be a barrier to virtual medicine access. STUDY DESIGN: A digital access screening tool was prospectively developed and launched in July 2021. Schedulers are prompted to complete this optional screening questionnaire at the time of patient intake, for video or in-person encounters. The parent is screened for access to a device and reliable internet or cellular data that could be used to participate in a video visit. These represented the primary study outcomes. A modality preference for an in-person visit, video visit, or no preference was also recorded. Patient demographics were retrospectively evaluated, and socioeconomic status was estimated using the Distressed Communities Index generated for each patient's zip code. For each zip code, the Distressed Communities Index produces a normalized, comparative distress score ranging from 0 ("prosperous") to 100 ("distressed"). RESULTS: 3885 patients were included, with median age of 5 years (IQR 1-11). Almost 74% were male, 71.3% were White, 20.9% had public insurance, and 2.9% required an interpreter. The median distress score was 14.2 (IQR 7.2-27.5). Screening revealed that 136 families (3.5%) lacked digital access. On multivariable logistic regression analysis, insurance type (p = 0.0020) and distress score (p = 0.0125) were significant predictors of digital access (Summary Table). Those patients who lacked access to a device (p < 0.0001) or reliable internet/cellular data (p < 0.0001) were more likely to prefer an in-person visit. DISCUSSION: Family screening revealed that there is a small but significant proportion of families who lack digital access, and this cohort disproportionately represents underserved communities with higher distress scores, likely reflecting lower socioeconomic status. Those families without digital access were more likely to prefer an in-person visit. Improved identification of these socially complex "at-risk" patients can assist in the development of more inclusive health care strategies. CONCLUSIONS: Despite the chance for virtual medicine to expand access for underserved populations, lack of digital tools may hinder its potential impact on health disparities in pediatric urology. Ongoing digital access screening and further studies are needed to design interventions tailored to the specific needs of our patients, allowing for more equitable pediatric urological care.

Urology Residency Training in Medically Underserved Areas Through the Integration of a Federally Qualified Health Center Rotation.

OBJECTIVE: To identify workforce related barriers to urologic care in Medically Underserved Areas (MUA) and Health Professional Shortage Areas (HPSA). Federally Qualified Health Centers (FQHC) are community-based organizations that aim to close gaps, but little is known about exposure to underserved areas during residency training. METHODS: The objective of this study was to characterize the experiences of urology residents who participated in a rotation within a FQHC. The study consisted of: (1) 12-item post-rotation self-assessment (2) review of career paths of former graduates who completed the rotation, and (3) retrospective review of patients treated at FQHC from 2016 to 2018. RESULTS: There were a total of 1735 patient visits, 97 were for cystoscopy, 76.36% of patients had Medicaid or no insurance. There were 1092 unique patients seen and 281 (25.73%) were referred for surgery. A majority of residents (100%) stated they had a better appreciation of treating patients in underserved areas. A majority of residents (71.6%) of residents said they were more likely to practice in an underserved area after residency. Among former graduates who rotated through the clinic, 100% (n = 4) were practicing in a MUA or HPSA. CONCLUSION: The integration of an FQHC during urology residency training was associated with highly favorable satisfaction by trainees. Given persistent workforce related shortages in urology, these findings support exposure to medically underserved areas during training.

Comparison of long-term outcomes in a 10-year experience of robotic cystectomy vs. open cystectomy.

To compare the outcomes of robotic-assisted (RARC) vs. open radical cystectomy (ORC) at a single academic institution. We retrospectively identified patients undergoing radical cystectomy for urothelial carcinoma of the bladder at our institution from 2007 to 2017. Data collected included age, sex, Body Mass Index (BMI), Charlson Age-Adjusted Comorbidity Index (CCI), final pathologic stage, surgical margins, lymph-node yield, estimated blood loss (EBL), 90-day complication rate, and length of stay (LOS). We evaluated overall survival (OS) and recurrence-free survival (RFS). Multivariable Cox proportional hazard models were used to adjust for covariates. We identified 232 patients (73 RARC, 159 ORC) who underwent radical cystectomy. Patients who underwent RARC were older (71.8 vs. 67.5, p < 0.05) and had higher CCI scores (6.2 vs. 5.3, p < 0.05). In comparing perioperative outcomes, RARC patients had lower EBL (500 vs. 850, p < 0.01), lower blood transfusion rate (p < 0.01), and lower lymph-node yield (12 vs. 20, p < 0.01), and higher ICU admission rate (29% vs. 16% p < 0.01). There was no difference in BMI (p = 0.93), sex (p = 0.28), final pathological stage (p = 0.35), positive surgical margins (p = 0.47), complications (p = 0.58), or LOS (p = 0.34). Kaplan-Meier analysis showed no difference in OS (p = 0.26) or RFS (p = 0.86). There was no difference in restricted mean survival time for OS (53 vs. 56 months, p = 0.81) or for RFS (65 vs. 64 months, p = 0.90). Cox multivariate regression models showed that surgical approach does not have a significant impact on OS (p = 0.46) or RFS (p = 0.35). Our study indicates that in our 10-year experience, patients undergoing there was no difference between RARC and ORC patients with respect to OS and RFS despite being older and having more comorbidities. Our work supports the importance of patient selection to optimize outcomes.

Anxiety, distress, and pain in pediatric urodynamics.

AIMS: No one has assessed urodynamic studies (UDS) to determine those steps that elicit the greatest anxiety, distress, and pain in children. We sought to systematically evaluate a child's UDS experience to mollify these reactions. METHODS: Prospective study involving children aged ≥5 undergoing UDS over a 6-month period (from 10 December 2018 to 22 May 2019). Upon arrival, patients completed a visual analog scale for anxiety (VAS-A, 0-10) about the upcoming procedure. A research assistant assessed the patient's behavior during each major step of UDS using a validated brief behavioral distress scale. Nursing staff also obtained patients' pain ratings (0-10) for these key elements. Immediately after UDS, each child completed a posttest VAS-A along with a survey about the UDS experience. RESULTS: A total of 76 UDS were observed; almost half included sphincter needle electromyography (EMG). Mean patient VAS-A scores were 2.3 before UDS, compared to 0.8 afterward (P < .001). The highest proportion of distressful behaviors were observed during EMG needle (31%) and urethral catheter (29%) insertion, in agreement with the highest mean pain scores of 3.2 and 2.7, respectively. Fifty-four percent of children reported not being completely aware of what was going to happen before the procedure and 50% of those patients exhibited at least one interfering or potentially interfering behavior. Similarly, 60% of children with no prior history of UDS exhibited at least one interfering or potentially interfering behavior. CONCLUSIONS: EMG needle and urethral catheter placement, initial urodynamic testing and not knowing what to expect were associated with greater pain and distress during pediatric UDS.

Association of Human Development Index with global bladder, kidney, prostate and testis cancer incidence and mortality.

OBJECTIVES: To describe contemporary worldwide age-standardized incidence and mortality rates for bladder, kidney, prostate and testis cancer and their association with development. MATERIALS AND METHODS: We obtained gender-specific, age-standardized incidence and mortality rates for 184 countries and 16 major world regions from the GLOBOCAN 2012 database. We compared the mortality-to-incidence ratios (MIRs) at national and regional levels in males and females, and assessed the association with socio-economic development using the 2014 United Nations Human Development Index (HDI). RESULTS: Age-standardized incidence rates were 2.9 (bladder) to 7.4 (testis) times higher for genitourinary malignancies in more developed countries compared with less developed countries. Age-standardized mortality rates were 1.5-2.2 times higher in more vs less developed countries for prostate, bladder and kidney cancer, with no variation in mortality rates observed in testis cancer. There was a strong inverse relationship between HDI and MIR in testis (regression coefficient 1.65, R2 = 0.78), prostate (regression coefficient -1.56, R2 = 0.85), kidney (regression coefficient -1.34, R2 = 0.74), and bladder cancer (regression coefficient -1.01, R2 = 0.80). CONCLUSION: While incidence and mortality rates for genitourinary cancers vary widely throughout the world, the MIR is highest in less developed countries for all four major genitourinary malignancies. Further research is needed to understand whether differences in comorbidities, exposures, time to diagnosis, access to healthcare, diagnostic techniques or treatment options explain the observed inequalities in genitourinary cancer outcomes.

Adverse pathologic characteristics in the small renal mass: implications for active surveillance.

INTRODUCTION: Evidence has demonstrated that tumor size is related to adverse oncologic outcomes in small renal tumors (≤ 4 cm). We evaluated the association of adverse pathologic features (APF) with tumor size and survival in patients with a small renal mass (SRM). MATERIALS AND METHODS: We retrospectively reviewed the pathologic characteristics of 380 surgically resected SRMs from a single institution. APFs included lymphovascular invasion, coagulative necrosis, sarcomatoid/rhabdoid features, papillary type II histology, and perinephric fat/renal sinus invasion. The number and type of APFs were compared with tumor size. Survival analysis was performed using the Kaplan-Meier method. RESULTS: There were 244 (64.2%) males and 136 (35.8%) females. The median age was 61 years, and median tumor size was 2.7 cm. The median follow up time was 65 months. A significant association was found between tumor size and presence of APFs (p = 0.018). At least 1 APF could be found in 22%, 32%, 36%, and 49% of tumors ≤ 1 cm, 1 cm-2 cm, 2 cm-3 cm, and 3 cm-4 cm, respectively. There were no differences in overall survival or recurrence free survival when compared by tumor size at diagnosis (p = 0.22 and 0.15 respectively). Compared to patients with ≤ 1 APFs, disease specific survival was worse for patients with ≥ 2 APFs (p < 0.002). CONCLUSION: Our data support that aggressive tumor biology in a SRM is associated with greater size. In patients with a SRM, the decision to pursue active surveillance and the trigger for intervention should take tumor size and APFs into consideration as this may have future oncologic implications.

Negative Multiparametric Magnetic Resonance Imaging of the Prostate Predicts Absence of Clinically Significant Prostate Cancer on 12-Core Template Prostate Biopsy.

OBJECTIVE: To determine the negative predictive value of multiparametric magnetic resonance imaging (mpMRI), we evaluated the frequency of prostate cancer detection by 12-core template mapping biopsy in men whose mpMRI showed no suspicious regions. METHODS: Six hundred seventy patients underwent mpMRI followed by transrectal ultrasound (TRUS)-guided systematic prostate biopsy from December 2012 to June 2016. Of this cohort, 100 patients had a negative mpMRI. mpMRI imaging sequences included T2-weighted and diffusion-weighted imaging, and dynamic contrast enhancement sequences. RESULTS: The mean age, prostate-specific antigen, and prostate volume of the 100 men included were 64.3 years, 7.2 ng/mL, and 71 mL, respectively. Overall cancer detection was 27% (27 of 100). Prostate cancer was detected in 26.3% (10 of 38) of patients who were biopsy-naïve, 12.1% (4 of 33) of patients who had a prior negative biopsy, and in 44.8% (13 of 29) of patients previously on active surveillance; Gleason grade ≥7 was detected in 3% of patients overall (3 of 100). The negative predictive value of a negative mpMRI was 73% for all prostate cancer and 97% for Gleason ≥7 prostate cancer. CONCLUSION: There is an approximately 3% chance of detecting clinically significant prostate cancer with systematic TRUS-guided biopsy in patients with no suspicious findings on mpMRI. This information should help guide recommendations to patients about undergoing systematic TRUS-guided biopsy when mpMRI is negative.

What's in a Number? Examining the Effect of a Dedicated Research Year on H-Index and Fellowship Decision-making.

OBJECTIVE: To assess the effect of a dedicated research year on the h-indices of residents and the pursuit of fellowship within a heterogeneous group of urology programs. We previously demonstrated that urology residents with a dedicated research year produce more than 2 times the number of publications than their counterparts in 5-year programs. However, we did not give consideration to the impact of these publications. MATERIALS AND METHODS: We obtained information on the publication output and pursuit of fellowship of graduates from the New York Section urology residency programs from 2009 to 2013. Data on peer-reviewed publications were obtained by PubMed query and h-index was documented from the Scopus database. RESULTS: During the 5-year study period, 148 individuals (116 M, 32 F) graduated from New York Section urology programs. The mean h-index was 4.6 for residents in 5-year programs compared with 8.1 for those in 6-year programs (P < .001). Residents with a dedicated research year were more likely to pursue fellowship training (79.3% vs 58.8%, P = .023) with no difference in the pursuit of accredited fellowship programs. Those residents who went on to fellowship training had a significantly higher h-index (6.2 vs 3.6, P = .001). CONCLUSION: Urology residents with a dedicated research year have almost 2 times the h-indices of their counterparts. Residents who pursue fellowship training also have higher h-indices. Residents who completed a dedicated research year were more likely to pursue fellowship training, although the accreditation status of these programs was variable.

The Difference a Year Can Make: Academic Productivity of Residents in 5 vs 6-Year Urology Programs.

OBJECTIVE: To evaluate the effect of a dedicated research year on academic productivity in a heterogeneous group of urology programs. METHODS: We obtained information on publication output for the past 5 years, from 2009 to 2013, of urology graduates from all 15 New York Section residency programs (n = 148). We recorded resident sex; whether the program has a dedicated year of research; number of residents per year; total number of publications per resident noting first, second, and third or greater authorship; and whether residents pursued fellowship training. RESULTS: Overall, the median number of total publications was 3 for residents in 5-year programs compared with 7 in 6-year programs (P = .0007). This difference remained significant when evaluating the number of publications per year as well as the number of first and third or greater authorship. Programs with 3 residents per year had significantly more publications than those with 1 or 2, regardless of research time. Graduates of 5-year programs were less likely than their 6-year counterparts to pursue fellowship training. There was a significantly higher publication output for those residents who went on to fellowship training. On multivariate analysis, 5- or 6-year program, the number of residents per year and pursuit of fellowship training remained statistically significant predictors of total publication number. CONCLUSION: Urology residents with a dedicated year of research produce more than 2 times the number of publications than their counterparts in 5-year programs. This dedicated research time and greater publication output were both indicative of the pursuit of fellowship training.

Three testicles in one hemiscrotum: an unusual presentation of polyorchidism.

Polyorchidism, or more than one testicle in a hemiscrotum, is a relatively rare phenomenon. It is often associated with several other conditions, including inguinal hernia, testicular maldescent, testicular torsion, hydrocele or hypospadias. In this report, we describe a patient who presented with three testicles in one hemiscrotum, which is a highly unusual presentation for an already uncommon condition. We also review the relevant literature as it relates to the need for surveillance due to the increased risk for malignancy.

Perivascular epithelioid cell tumour of the bladder.

A 39-year-old woman presented with a long history of pelvic pain and urinary urgency. Prior workup by her primary care doctor had been negative. The patient's gynaecologist ultimately referred her to a urologist following an ultrasound that revealed a possible bladder mass. MRI of the abdomen and pelvis demonstrated a 4 cm soft tissue lesion arising from the bladder. Cystoscopy showed an atypical mass on the anterior bladder wall, and pathological examination of the TURBT (transurethral resection of the bladder tumour) specimen revealed a perivascular epithelioid cell tumour (PEComa) with involvement of the detrusor muscle. The patient underwent a robotically assisted laparoscopic partial cystectomy. Final pathology confirmed a PEComa with negative margins. The patient had an uncomplicated postoperative course and is doing well following surgery. A surveillance cystoscopy at 6 months showed no evidence of recurrence. This case underscores the variability of clinical presentation of PEComas while proposing an appropriate method of surgical management.

Patient perception of transvaginal mesh and the media.

OBJECTIVE: To assess the penetration of media-based information on transvaginal mesh (TVM) in our patient population and to determine whether exposure affects patient opinion. Since the 2011 Federal Drug Administration communication on TVM, many advertisements from legal practices have been directed toward patients. MATERIALS AND METHODS: An 18-item survey was administered to female patients at 2 sites from August 2012 to April 2013. Patients presenting with new diagnoses of pelvic organ prolapse or stress urinary incontinence or patients who reported prior mesh surgery were excluded. RESULTS: Ninety-nine questionnaires were completed. Sixty-six of the patients (67%) were aware of TVM; and of these, 38 (58%) cited advertisements as the initial source of information. Only 12% were aware of the Food and Drug Administration's communication. Regarding opinion of TVM, 9% chose "it is a safe product," 9% "safety depends on factors related to patient," 4.5% "not a safe product," 1.5% "safety depends on the doctor," 68% "I don't know," and 4.5% marked 2 selections. Only 12% indicated knowing the difference in the use of TVM for pelvic organ prolapse vs stress urinary incontinence. When asked what influenced their opinion of TVM the most; responses were as follows: advertisement (33.3%), medical professional (22.7%), friends or family who underwent TVM procedure (12.1%), media article (6.1%), and "not sure" (25.8%). CONCLUSION: Advertisements of TVM lawsuits had a high penetration into our patient population but did not produce an overtly negative response in our sample. Clinicians should be aware of the impact of these advertisements on patient opinion and counsel patients accordingly with unbiased and scientifically accurate information.

Paratesticular fibrous pseudotumour.

A 38-year-old man presented with a 2-year history of an enlarging scrotal nodule. Scrotal ultrasound revealed two soft tissue masses separate from the testicle in the right scrotum measuring 1.7 and 0.8 cm. The patient underwent excision of the scrotal nodules, revealing firm, white tissue with a smooth, nodular surface. On histology, the lesions appeared fibrous with scattered capillaries and areas of inflammatory infiltrate consistent with paratesticular fibrous pseudotumour. On a follow-up ultrasound at 6 months, he had no evidence of recurrence.

Recurrent nephrolithiasis associated with atazanavir use.

A 64-year-old man with HIV on antiretroviral therapy (including atazanavir, a protease inhibitor) presented with left flank pain, nausea and vomiting. A kidney stone was suspected, and a CT scan demonstrated left hydronephrosis but failed to demonstrate nephrolithiasis or extrinsic compression. The patient had a ureteral stent placed which relieved his symptoms. A few months later, he underwent left ureteroscopy and a large ureteral calculus was found. The stone was removed and analysis showed 43% atazanavir and 57% calcium oxalate. Several months later, the patient developed flank pain on the opposite side. A renal ultrasound suggested right-sided nephrolithiasis and he subsequently underwent ureteroscopy with laser lithotripsy of two stones. Stone analysis showed that they were composed of 100% atazanavir. This case highlights the fact that patients treated with protease inhibitors remain at risk for developing nephrolithiasis. Ultrasonography can be a useful diagnostic tool in the setting of these radiolucent calculi.

An animal explant model for the study of human cutaneous squamous cell carcinoma.

We established a human tissue explant model to facilitate study of cutaneous squamous cell carcinoma. We accomplished this by implanting debulked SCC, from surgical discard, into nude rats. Human SCC remained viable and continued to proliferate for at least 4 weeks and showed evidence of neovascularization. At 4 weeks, SCC implants showed a trend toward increased PCNA positive cells compared to fresh SCC cells/mm(2) tissue) supporting continued proliferation throughout engraftment. Von Willebrand's Factor (VWF) positive cells were found within implants and likely represented rat vessel neovascularization. Human Langerhans' (Langerin+) cells, but no T cells (CD3+, CD8+, FoxP3+), macrophages (CD163), or NK cells (NKp46), were present in SCC implants at 4 weeks. These findings support the possibility that LCs fail to migrate from cutaneous SCC and thus contribute to lack of effective antitumor response. Our findings also provide a novel model system for further study of primary cutaneous SCC.

Renal metastasis of an ovarian granulosa cell tumour inducing growth of a cystic nephroma.

A 44-year-old woman presented with a large pelvic mass. Pathology revealed a granulosa cell tumour of the left ovary. The patient was followed after surgery with inhibin B levels and interval imaging. Six years later, she began to experience severe back pain. A vertebral biopsy was positive for metastatic granulosa cell tumour. She underwent radiation to the spine. Inhibin B levels began to rise and, several months later, a CT scan showed a large heterogeneous mass essentially replacing the left kidney. She underwent an open left radical nephrectomy. Pathology revealed a 12 cm cystic nephroma with a 5 cm nodule of metastatic granulosa cell tumour. Immunohistochemistry demonstrated that the mass was inhibin and oestrogen receptor positive. This is a novel presentation of these coexisting pathologies. This unique case sheds light on the possibility of induction of cystic nephroma by the altered hormonal environment created by a granulosa cell tumour metastasis.

Ultrasonography in prostate cancer: current roles and potential applications in radiorecurrent disease.

The use of ultrasound technology for prostate cancer imaging has evolved over many years. In order to fully appreciate today's application of prostate ultrasound in the primary diagnostic setting as well as for radiorecurrent prostate cancer, it is helpful to understand the progression of this technology from its inception. This review begins with a brief history of the development of ultrasonography for the prostate. This is followed by a summary of the data evaluating ultrasound in the primary diagnosis of prostate cancer. Its application in the post-treatment setting is then addressed. Finally, several emerging technologies are discussed, including contrast-enhanced ultrasound, elastography and HistoScanning. These new modalities may hold promise for identifying incompletely ablated prostate tissue following radiation therapy or other ablative techniques.

Varicocelectomy is associated with increases in serum testosterone independent of clinical grade.

OBJECTIVE: To determine whether the varicocele grade is related to the degree of improvement in serum testosterone levels after varicocelectomy. MATERIALS AND METHODS: We performed a retrospective review of men with a total serum testosterone level <400 ng/dL who had undergone microsurgical subinguinal varicocelectomy for infertility and/or hypogonadism. All men had clinically palpable left varicoceles and preoperative and postoperative total serum testosterone levels available. For patients with bilateral varicoceles, the greatest grade on either side was used to stratify the patients. The men with an isolated, left-side, grade I varicocele were not offered varicocelectomy. The changes in the testosterone levels were evaluated, with the results expressed as the mean ± standard error. P ≤.05 was considered statistically significant. RESULTS: A total of 59 patients had undergone bilateral varicocelectomy and 19 unilateral varicocelectomy. Overall, an increase in testosterone was seen in 65 of the 78 men (83%) in the present study. The mean follow-up was 7 months. The mean serum testosterone level increased from 308.4 to 417.5 ng/dL, with a mean increase of 109.1 ± 12.8 ng/dL (n = 78). The improvements in the serum testosterone levels were seen regardless of the clinical grade. CONCLUSION: Microsurgical varicocelectomy resulted in significant increases in the serum testosterone level, independent of the varicocele grade.
