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.

Salvage radical prostatectomy as management of locally recurrent prostate cancer: outcomes and complications.

PURPOSE: Management of prostate cancer following radiation therapy remains challenging, especially for younger men or those with life expectancy greater than 10 years. We outline the efficacy, safety and adequacy of radical prostatectomy for the treatment of radiorecurrent localized prostate cancer. METHODS: A systematic review was performed in September 2012 searching MEDLINE articles from 1980 to 2012 on salvage radical prostatectomy. We excluded unpublished data and non-English-language articles. RESULTS: The ideal candidate for salvage radical prostatectomy (SRP) has a life expectancy greater than 10 years, a PSA < 10 ng/ml and whose initial clinical staging was T1 or T2. A prostate biopsy and imaging studies to rule out metastatic disease should be performed prior to SRP. Salvage RP has a high complication rate, but this appears to be decreasing over time. Urinary continence rates range from 36 to 81%, whereas erectile function following SRP was generally poor with less than 30% of men regaining adequate erectile function. Men with good erectile function prior to SRP fared better than those with pre-operative erectile dysfunction. Biochemical recurrence-free probability at 5 years ranged from 37 to 55% and the estimated cancer-specific survival at 10 years ranged from 70 to 83%. Minimally invasive SRP is feasible and early outcomes suggest that this approach is not inferior to open surgery. CONCLUSION: SRP offers a potentially curative option with proven long-term disease-free survival in appropriately selected patients. Given the morbidity of this procedure, judicious patient selection and referral to providers experienced with salvage surgery may optimize patient outcomes.

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.

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.

Nomograms to predict patency after microsurgical vasectomy reversal.

PURPOSE: After undergoing vasectomy up to 6% of men will elect to undergo vasectomy reversal. For these men paternity can be achieved with vasectomy reversal or surgical sperm retrieval coupled with assisted reproduction. Nevertheless, it remains difficult for surgeons to accurately counsel men on the chance of patency after vasectomy reversal. MATERIALS AND METHODS: A retrospective review was conducted of 548 patients who underwent microsurgical vasectomy reversal. Surgery was considered successful if sperm concentration was 100,000 or more sperm per ml, total count was 100,000 or more sperm per ejaculate, motile sperm were present and there was no evidence of subsequent failure. A multivariate logistic regression model was constructed to calculate the probability of having a successful vasectomy reversal and nomograms for patency were generated from this model. RESULTS: A total of 548 patients met the inclusion criteria for this study. Mean followup was 1.8 ± 0.10 years. Mean patient age was 43.4 ± 0.3 years and mean duration of obstruction was 10.4 ± 0.2 years. Two nomograms to predict patency were generated, one for preoperative counseling and a second for postoperative counseling. The factors with the largest effect on patency were average testicular volume and obstruction duration. The factor with the least effect was the presence of sperm granuloma. The concordance index for the preoperative and the postoperative nomograms was 0.64 and 0.66, respectively. CONCLUSIONS: To our knowledge this represents the first use of nomograms to predict the likelihood of patency after microsurgical vasectomy reversal. These nomograms may prove useful to guide further treatment decisions.

Older age is associated with similar improvements in semen parameters and testosterone after subinguinal microsurgical varicocelectomy.

PURPOSE: It is generally accepted that men with clinically palpable varicocele are at high risk for a progressive decrease in fertility and testosterone levels with time. Varicocelectomy is thought to improve testicular function or at least halt the accelerated decrease in testicular function associated with varicocele. Substantial controversy exists as to whether varicocelectomy is effective in older men, possibly due to irreversible testicular damage or limited potential for recovery from varicocele induced damage. MATERIALS AND METHODS: We retrospectively reviewed the records of men who underwent microsurgical subinguinal varicocelectomy, as done by a single surgeon. Demographics, patient questionnaires, operative notes, charts, testosterone and semen analysis were reviewed. Patients were divided into 3 groups based on age at surgery, including less than 30, 30 to 39 and 40 years or greater. RESULTS: A total of 272 men met study inclusion criteria. In all 3 age groups we noted similar testosterone and baseline semen analysis parameters. There were significant increases in sperm concentration and total sperm count in all age groups. When analysis was restricted to men with baseline testosterone 400 ng/dl or less, there was a mean 110, 133 and 136 ng/dl increase in 21 men who were 40 years old or older, in 30 who were 30 to 39 years old and in 21 who were younger than 30 years, respectively. CONCLUSIONS: Microsurgical varicocelectomy resulted in significant increases in sperm concentration, total sperm count and testosterone in all age groups studied, including men in the fifth and sixth decades of life. Microsurgical varicocelectomy should be offered to older men for infertility and/or hypogonadism.

Varicocele as a risk factor for androgen deficiency and effect of repair.

OBJECTIVE: • To determine whether men with varicoceles have lower testosterone levels than those without and to ascertain if testosterone levels increase after varicocelectomy. PATIENTS AND METHODS: • We measured preoperative testosterone levels in 325 men with palpable varicoceles and in 510 men with vasectomy reversal without varicoceles who served as a comparison group. • The testosterone levels between groups were compared by age. Of the men with varicoceles, 200 had data on both pre- and postoperative testosterone levels, which were compared to assess postoperative changes. RESULTS: • Men with varicocele had significantly lower testosterone levels than the comparison group, with mean (sd) levels of 416 (156) vs 469 (192) ng/dL (P < 0.001). This difference persisted when analysed by age. • The testosterone levels significantly increased after repair from 358 (126) to 454 (168) ng/dL (P < 0.001). • Of the 70% of patients with postoperative improvement in testosterone levels, the mean (sd) increase in testosterone was 178 (142) ng/dL. The percentage change in testosterone levels was: 30% had no increase, 41% increased by ≤ 50%, 19% increased between by 51-100%, and 10% increased by >100%. • There was no association between change in testosterone level and age, laterality of varicocele, or varicocele grade. CONCLUSIONS: • Men with varicoceles had significantly lower testosterone levels than the comparison group of men with vasectomy reversal. • Microsurgical varicocele ligation resulted in a significant increase in serum testosterone levels in more than two-thirds of men. • These findings suggest that varicocele is a significant risk factor for androgen deficiency and that repair may increase testosterone levels in men with varicocele and low testosterone levels.

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.

The emerging role of robotics in adrenal surgery.

Robotic surgery is being performed more frequently for a variety of urologic procedures. Since the first robotic adrenalectomy less than a decade ago, this modality has gained increased acceptance in the urologic community and has been employed with increased frequency in minimally invasive centers. This review evaluates the current literature on robotic adrenalectomy, its indications, as well as its advantages and limitations compared with other forms of surgical management of adrenal pathology.

Laparoscopic radical nephrectomy for renal masses 7 centimeters or larger.

OBJECTIVE: To report our operative experience and oncologic outcomes for the laparoscopic management of large renal tumors. METHODS: All laparoscopic and hand-assisted laparoscopic radical nephrectomies performed at our institution were reviewed. Thirty patients with tumors >or=7cm and a pathologic diagnosis of renal cell carcinoma were included. RESULTS: Mean operative time was 175.7+/-24.5 minutes, and mean estimated blood loss was 275.5+/-165.8 mL. No case required conversion to open radical nephrectomy. The mean hospital stay was 2.4+/-1.6 days. Four patients (13%) had minor complications. Of the 30 tumors, 18 were pathologic stage T2, 9 were stage T3a, 2 were stage T3b, and one was stage T4. At a mean follow-up of 30 months (range, 10 to 70), 22 patients (73%) were alive without evidence of recurrence, and 5 patients (17%) were alive with disease. One patient (3%) died of complications related to renal cell carcinoma, and 2 patients (7%) died from other causes. Overall survival was 90%, cancer-specific survival was 97%, and recurrence-free survival was 80%. CONCLUSION: Laparoscopic radical nephrectomy for large tumors is a technically challenging operation. However, in experienced hands, it is a reasonable therapeutic option for the management of larger RCC neoplasms.

Laparoscopic adrenalectomy for large adrenal masses.

Open adrenalectomy has been the gold-standard therapy for adrenal neoplasms. Minimally invasive treatments, however, have assumed a more central role in the management of these lesions. The traditional benefits of laparoscopy, including reduced blood loss, shorter hospital duration, and improved convalescence, extend to adrenal disease without compromising the oncologic efficacy of the surgery. Contemporary series suggest that minimally invasive surgery is also a reasonable therapeutic modality for larger adrenal masses. Laparoscopic adrenalectomy for these large masses is a technically demanding procedure that should be undertaken by experienced laparoscopic surgeons familiar with retroperitoneal anatomy and adept with vascular techniques in the event of an open conversion. Oncologic outcomes collectively suggest that in the setting of adequate surgical resection, recurrence patterns relate more to disease-process biology than surgical approach. Neither size criteria, suspicion of malignancy, nor locally invasive disease should be considered an absolute contraindication to laparoscopic adrenalectomy.

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.

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.

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.

Laparoendoscopic single-site radical nephrectomy for large renal masses.

PURPOSE: To report our operative experience and short-term outcomes for the laparoendoscopic single-site (LESS) management of large renal tumors and tumors of advanced stage. PATIENTS AND METHODS: Ten consecutive patients underwent LESS-radical nephrectomy (RN) for large (≥ 7 cm) and/or locally advanced tumors (>T(2)). Intraoperative, postoperative, and short-term follow-up data were analyzed. RESULTS: Median surgical time was 146 minutes (range 73-164 min), and median estimated blood loss was 100 mL (range 25-400 mL). No procedure needed conversion to open RN or hand-assisted laparoscopic RN. The median hospital stay was 47 hours (range 42 hours-12 days). One (10%) patient had a minor complication (postoperative fever treated with antibiotics) and one (10%) patient had a major complication (small bowel obstruction necessitating reoperation). Of the 10 tumors, 2 were pathologic stage T(1b), 4 were pathologic stage T(2), and 4 were stage T(3a). At a median follow-up of 12.3 months (range 1-16 mos), six (60%) patients were alive without evidence of recurrence, and 4 (40%) patients were alive with disease. Of those four patients, all four had known metastatic disease before surgery. CONCLUSION: LESS-RN for large or advanced stage renal masses is a technically challenging operation. In experienced hands, however, it is a safe and feasible therapeutic option for the management of these tumors.

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.
