The need for specialized training for adults with congenital urologic conditions: differences in opinion among specialties

Introduction: The aim of this study was to survey pediatric urology fellowship directors (PFD) and adult reconstruction fellowship directors (AFD) to assess who they believe has sufficient training to care for adults with congenital urologic conditions (ACUC). Material and methods: An online survey was created to assess attitudes towards specific training to care for ACUC. The survey was administered to 27 PFD and 26 AFD [16 from genitourinary reconstructive surgery (GURS) and 10 from female pelvic medicine and reconstructive surgery (FPMRS)]. Both groups were asked if specific training is warranted, and if general urologists, pediatric urologists or adult reconstructive urologists were sufficiently trained to care for ACUC. Results: A total of 26 (96%) PFD and 10 (39%) AFD completed the survey. All PFD were fellowship trained in pediatrics. Of the AFD, 5 were GURS trained, 4 were FPMRS trained and 1 was not fellowship trained. The majority (65% PFD, 90% AFD) believed specific training is warranted. Few believed general urologists have sufficient training (8% PFD, 20% AFD). Most PFD believed pediatric urologists have sufficient training (85%), but a minority believed those with adult reconstructive training do (40%). Conversely, a minority of AFD believed that pediatric urologists have sufficient training (40%), while those with adult reconstructive training do (FPMRS: 67%, GURS: 60%). Conclusions: Both pediatric and adult reconstructive urologists believe specific training to care for adults with congenital urologic conditions is warranted. Neither group considers the other to be ideally suited to care for this co

Current opinions regarding care of the mature pediatric urology patient

Introduction With continued improvements in pediatric urology care of patients with complex congenital genitourinary conditions, many survive into adulthood. This fact has created a challenging situation of transitioning from pediatric to adult care. Establishing long-term follow-up with appropriate specialists is a critical part of a successful transition to adulthood for this population. Objective This study sought to elucidate current practices and opinions regarding the management of adult complex genitourinary patients by pediatric urologists, in order to determine if a consensus for adult care exists. Study design An anonymous, 15-question online survey was created to address practice patterns and opinions regarding the transition of care of complex genitourinary patients. An invitation to participate was distributed via email to 200 pediatric urologists who were members of the American Urological Association. Complex genitourinary patients were defined broadly as those with a history of: spina bifida, bladder exstrophy, cloacal exstrophy, cloacal anomalies, posterior urethral valves or disorders of sex development. Fisher's exact test was used for analysis. Results The response rate was 31.0% (62/200). Two-thirds (67.7%) cared for adults with complex genitourinary conditions. Overall, 51.6% of pediatric urologists felt that general urologists best follow adult patients, but only 6.5% recommended this for patients with prior complex genitourinary reconstruction (P < 0.001). Instead, the majority (80.6%) felt that a pediatric or adult urologist with an interest and training in adolescent/transitional urology who routinely performs such procedures would provide optimal care. Follow-up by a primary care physician alone was not recommended. Recommendations did not change if patients had developmental delay or lived independently (P = 0.47 and P = 0.72, respectively). Overall, 69.4% would refer mature complex genitourinary patients to a urologist with interest and training in adolescent/transitional urology, if one was available. However, only 45.2% had such an individual available in their practice (P < 0.001). Discussion In the present study, the opinions of pediatric urologists regarding optimal providers of long-term follow-up for mature complex genitourinary patients were presented. While the results may not represent the views of the entire pediatric urology community, responses from motivated individuals with a particular interest in transition care may be especially valuable. Although the present study did not outline a mechanism for improving transitional care, it offered valuable information on prevailing opinions in this area. Finally, the opinions of mostly North American Pediatric Urologists were presented, which may not apply to other healthcare settings. Conclusions Pediatric urologists appeared to be virtually unanimous in recommending that urologists provide the most appropriate long-term follow-up of patients with congenital genitourinary conditions. Specifically, 80% recommended that patients with prior complex surgical reconstruction be followed by a urologist with specific interest, training and experience in the area of transitional urology. The data suggest that this may be an unmet need of these specialists and may signify the need for specific training in the care of such patients

Epidural Analgesia Decreases Narcotic Requirements in Low Level Spina Bifida Patients Undergoing Urologic Laparotomy for Neurogenic Bladder and Bowel

Purpose Concern of anatomical anomalies and worsening neurologic symptoms has prevented widespread use of epidural catheters in patients with low level spina bifida (LLSB). We hypothesize that thoracic epidural placement in the T9-T10 interspace is safe and decreases narcotic requirements in LLSB patients following major open lower urinary tract reconstruction (LUTR). Materials and Methods We reviewed consecutive LLSB patients who had LUTR and epidurals for post-operative pain control. Controls were LLSB patients who received single shot transversus abdominis plane (TAP) blocks with similar procedures. Complications from epidural placement, including changes in motor and sensory status were recorded. Opioid consumption was calculated utilizing equivalent IV morphine doses. Mean and maximum pain scores on post-operative day (POD) 0-3 were calculated. Results 10 LLSB patients who had lower urinary tract reconstruction and epidurals were matched to 10 LLSB patients who had lower urinary tract reconstruction and transverse abdominis plane blocks. Groups were demographically similar. All had full abdominal sensation and functional levels at or below L3. No epidural complications or changes in neurological status were noted. The epidural group had decreased opioid consumption on POD 0-3 (0.75 mg/kg vs. 1.29 mg/kg, p=0.04). Pain scores were similar or improved in the epidural group. Conclusions Thoracic epidural analgesia appears to be a safe and effective opioid sparing option to assist with post-operative pain management following lower urinary tract reconstruction in LLSB patients

Cost-effectiveness analysis of the management of distal ureteral stones in children

Objective To determine the most cost-effective approach to the management of distal ureteral stones in children given the potential for recurrent renal colic during a trial of passage versus potential stent discomfort and complications of ureteroscopy. Methods We developed a decision tree to project costs and clinical outcomes associated with observation, medical explusive therapy (MET), and ureteroscopy for the management of an index patient with a 4mm distal ureteral stone. We determined which strategy would be least costly and offer the most pain-free days within 30 days of diagnosis. We performed a one-way sensitivity analysis on the probability of successful stone passage with MET. We obtained probabilities from the literature and costs from the 2016 Pediatric Health Information System Database. Results Ureteroscopywas the costliest strategy but maximized the number of pain-free days within 30 days of diagnosis ($5,282/29 pain-free days). MET was less costly than ureteroscopybut also less effective ($615/21.8 pain-free days). Observation cost more than MET and was also less effective ($2,139/15.5 pain-free days). The one-way sensitivity analysis on the probability of successful stone passage with MET demonstrated that ureteroscopyalways has the highest net monetary benefits value and is therefore the recommended strategy given a fixed WTP. Discussion Using a rigorous decision-science approach, we found that ureteroscopy is the recommended strategy in children with small distal ureteral stones. Although it cost more than MET, it resulted in more pain-free days in the first 30 days following diagnosis given the faster resolution of the stone episode

Transitioning Young Adults with Neurogenic Bladder – Are We Asking Too Much?

Introduction Significant numbers of young adults with chronic health conditions fail to transition. Objective We aimed to evaluate how ready urologic patients who have transitioned were actually prepared for that process. Due to the cognitive impairments frequently seen with spina bifida (SB), we hypothesize that these individuals will be less prepared to transition medical care to adult providers compared to their healthy counterparts. Methods Participants included consecutive patients in the transitional SB clinic at our institution and controls (college student without obvious physical disability or interest in healthcare related fields aged 18-25). Both groups were administered the Transition Readiness Assessment Questionnaire (TRAQ) over a nine-month period. Five TRAQ domains assess 20 skills necessary to transition. Likert scale responses range from 1 “No, I do not know how” to 5 “Yes, I always do this when I need to” (which we considered appropriate for transitioned patients). Demographics and the number of daily medications taken were collected. Patients and healthy controls were compared using 1) total and domain TRAQ scores, 2) the proportion of non-transitioned skills (“1”) and 3) fully transitioned skills (“5”). Non-parametric statistics were used. Results 43 unique SB patients (30.8% shunted, 46.5% female) and 100 controls were enrolled. SB patients were older than controls (21 vs 20 years, p<0.001). There was no gender difference between groups (p=0.33). Transitioned patients and college students were fully transitioned only in the “Talking with Providers” domain ( Figure ). College students performed significantly better than patients in the domains of “Appointment Keeping” (p=0.04) and “Tracking Health Issues” (p=0.02). Transitioned patients were less likely to be interested in learning how to perform skills in the domains of “Appointment Keeping” and “Tracking Health Issues” (p<0.001 for both domains). Discussion We describe the transition readiness of young adults with SB compared to healthy controls and other youths with chronic health conditions. Limitations include the small sample size, potentially limiting generalizability, as well as cross-sectional nature. Conclusion “Transitioned” patients with SB had lower TRAQ scores in some domains compared to healthy college students, who themselves had scores indicating that they were not fully ready for transition. Increased attention to transition readiness in people with SB is necessary, as even healthy young adults struggle with these tasks and are poorly prepared for transition

The ability of a limited metabolic assessment to identify pediatric stone formers with metabolic abnormalities

Introduction American Urological Association guidelines recommend a urinary metabolic evaluation after the first stone event in all pediatric stone patients. Prior studies identified hypercalciuria and urine hypovolemia as the most common abnormalities in children with urolithiasis. Recent data suggest that hypocitraturia is most prevalent. It was hypothesized that a limited evaluation would detect the majority of clinically significant metabolic abnormalities in pediatric stone formers. Material and methods A retrospective analysis of all children (<18 years of age) with renal/ureteral calculi evaluated at the study institution from 2005 to 2015 was performed. Children with ≥ one 24-h urinary metabolic profile after a clinical visit for renal/ureteral calculi were included. Those with bladder stones and those with undercollection or overcollection or missing urinary creatinine were excluded. Demographics and data from the first urinary metabolic profile and stone analyses were collected. The sensitivity, specificity, and positive and negative predictive value (NPV) of a limited urinary metabolic evaluation consisting of four parameters (24-h calcium, citrate, and oxalate and low urinary volume) were compared to a complete urinary metabolic profile. The number and type of metabolic abnormalities that would have been missed with this limited evaluation weredetermined. Results Of 410 patients, 21 were excluded for age ≥18 years, 13 for bladder stones, 248 for overcollections, 38 for undercollections, and 10 for missing creatinine. This left 80 patients for inclusion: median age 11.4 years, 60% female, and 96.3% white. Of the entire cohort, 69.6% had hypocitraturia, 52.5% had low urine volume, and 22.5% had hypercalciuria. Sensitivity was 87.5%. Specificity could not be calculated because no patients had a normal complete metabolic evaluation. The NPV was zero, and the positive predictive value was 100%, but these are artifacts resulting from the absence of patients with a normal complete metabolic evaluation. Of the 80 patients, 10 had at least one abnormality missed by a limited metabolic evaluation (Table 1). The missed abnormalities were high pH (n = 6), abnormal 24-h phosphorus (low in 1 patient and high in 1 patient), low 24-h magnesium (n = 3), low 24-h potassium (n = 3), and high 24-h sodium (n = 4). Discussion A limited urinary metabolic evaluation would have detected the vast majority of clinically significant metabolic abnormalities in the study sample. Approximately two-thirds of the study patients submitted inadequate 24-h urine specimens. Conclusions A simplified approach to metabolic evaluation in first-time stone formers with a stone analysis available was proposed. This streamlined approach could simplify the metabolic evaluation and reduce health care costs

Initial collection of an inadequate 24-hour urine sample in children does not predict subsequent inadequate collections

Introduction Approximately half of adult stone formers submit specimens that are either under or over collections as determined by 24-h creatinine/kg. Previously identified predictors of inadequate collection in adults include female sex, older age, higher body mass index (BMI), vitamin D supplementation, and weekday collection. Objective The objective of this study is to determine risk factors for inadequate 24-h urinary specimen collection in the pediatric population. Study design A retrospective analysis of all children (<18 years of age) with renal and/or ureteral calculi evaluated at the study tertiary care pediatric center from 2005 to 2015 was performed. Those who had at least one 24-h urinary metabolic profile after a clinical visit for kidney and/or ureteral stones were included; children with bladder stones were excluded. Adequate collections had a urine creatinine of 10–15 mg/kg/24 h. A bivariate analysis of potential factors associated with inadequate collection of the initial urinary metabolic profile, including child demographics, parental socio-economic factors, history of stone surgery, and weekday vs. weekend urine collection, was performed. A mixed-effects logistic regression, controlling for correlation of specimens from the same patient, was also performed to determine whether an initial inadequate collection predicted a subsequent inadequate collection. Results Of 367 patients, 80 had an adequate collection (21.9%): median age, 13 years (interquartile range, 8–16); 61.1% female; 93.5% white; 19.5% obese; and 13.0% overweight. No parental or child factors were associated with inadequate collection (Summary Table). Of inadequate collections, more than 80% were over collections. In the 175 patients with more than one 24-h urinary specimen collection, the effect of an initial inadequate collection on subsequent inadequate collections was not significant after controlling for the correlation of samples from the same patient (p = 0.8). Discussion Any parental or child factors associated with the collection of inadequate 24-h urine specimens in children were not found. An initial inadequate collection does not predict subsequent inadequate collections. It was surprising that >80% of the inadequate collections were over collections rather than under collections. Possible explanations are that children collected urine samples for longer than the 24-h period or that stone-forming children produce more creatinine per 24-h period than healthy children due to hyperfiltration. Conclusion Inadequate collections are very common, and the risk factors for them are unclear. A repeat collection would be suggested if the first is inadequate. Further studies must be planned to explore barriers to accurate specimen collection using qualitative research methodology

Long-term outcomes of catheterizable continent urinary channels: what do you use, where you put it and does it matter?

Introduction Appendicovesicostomy (APV) and Monti ileovesicostomy (Monti) are commonly used catheterizable channels with similar outcomes on short-term follow-up. Their relative long-term results have not been previously published. Objective Our goal was to assess long-term durability of APV and Monti channels in a large patient cohort. Study design In this retrospective cohort study, we retrospectively reviewed consecutive patients ≤21 years old undergoing APV and Monti surgery at our institution (1990–2013). We collected data on demographics, channel type, location, continence and stomal and subfascial revisions. Kaplan–Meier survival and Cox proportional hazards analysis were used. Results Of 510 patients meeting inclusion criteria, 214 patients had an APV and 296 had a Monti (50.5% spiral Monti). Median age at surgery was 7.4 years for APV (median follow-up: 5.7 years) and 8.7 years for Monti (follow-up: 7.7 years). Stomal stenosis, overall stomal revisions and channel continence were similar for APV and Monti (p ≥ 0.26). Fourteen APVs (6.5%) had subfascial revisions compared to 49 Montis (16.6%, p = 0.001). On survival analysis, subfascial revision risk at 10 years for APV was 8.6%, Monti channels excluding spiral umbilical Monti: 15.5% and spiral umbilical Monti: 32.3% (p < 0.0001, Figure). On multivariate regression, Monti was 2.09 times more likely than APV to undergo revision (p = 0.03). The spiral Monti to the umbilicus, in particular, was 4.23 times more likely than APV to undergo revision (p < 0.001). Concomitant surgery, gender, age and surgery date were not significant predictors of subfascial revision (p ≥ 0.17). Stomal location was significant only for spiral Montis. Discussion Our study has several limitations. Although controlling for surgery date was a limited way of adjusting for changing surgical techniques, residual confounding by surgical technique is unlikely, as channel implantation technique was typically unrelated to channel type. We did not include complications managed conservatively or endoscopically. In addition, while we did not capture patients who were lost to follow-up, we attempted to control for this through survival analysis. Conclusions We demonstrate, durable long-term results with the APV and Monti techniques. The risk of channel complications continues over the channel's lifetime, with no difference in stomal complications between channels. At 10 years after initial surgery, Monti channels were twice as likely to undergo a subfascial revision (1 in 6) than APV (1 in 12). The risk is even higher in for the spiral umbilical Monti (1 in 3)

Comparison of Intraoperative and Early Postoperative Outcomes of Caudal Versus Dorsal Penile Nerve Blocks for Outpatient Penile Surgeries

Objective To compare intraoperative and 1-hour postoperative outcomes in caudal versus dorsal penile nerve block (DPNB) patients undergoing penile surgeries. Material and Methods We performed a retrospective cohort study of males 3. Secondary outcomes were intraoperative/post-anesthesia care unit (PACU) narcotics, pre-incision anesthesia time, adjusted operating room charges and complications. We performed bivariate and multivariable analyses controlling for demographic/procedure characteristics and clustering by surgeon. Results Of 738 patients, (mean age 2.1 years) 74.1% had a caudal. DPNB patients were more likely to have a maximum pain score >3 (19.5% vs. 8.1%, p 3 (95% CI 1.7- 4.4, p<0.0001) and 5.2 times the odds of intraoperative/PACU narcotic administration (95% CI 3.3-8.1, p<0.0001). In multivariable analyses, caudal patients had longer pre-incision anesthesia time (27.9 ± 7.4 vs. 19.5 ± 6.6 minutes, p<0.0001) and higher adjusted operating room charges ($12,760 ± 4077 vs.$9,402 ± 3741, p=0.01). Conclusion Caudal blocks may offer a small advantage in the immediate postoperative period although cost-effectiveness is unproven
