Manual Dexterity Predictors of Artificial Urinary Sphincter Success.

OBJECTIVE: To determine better in-office measures for artificial urinary sphincter outcomes, we investigated the ability of preoperative timed peg-transfer, pinch strength, grip strength, and Disabilities of the Arm Shoulder and Hand Outcome questionnaire in predicting postoperative satisfaction, confidence, and ease of use of artificial urinary sphincter placement for stress urinary incontinence. MATERIALS AND METHODS: A timed 9-hole peg test, pinch and grip strength assessment, and upper extremity questionnaire were administered during the preoperative visit before sphincter placement. In addition to standard preoperative workup, short-form International Consultation of Incontinence Questionnaire and physician handshake were recorded. Activation occurred 6 weeks after surgery along with assessment of adequacy of pump placement. Three months from surgery a repeat incontinence questionnaire and a survey measuring satisfaction, difficulty of use, and confidence were given. Correlation between preoperative assessment variables and the postoperative questionnaire was assessed. RESULTS: Thirty-nine patients were included. Average age and body mass index were 68.8 years and 28.8 kg/m2, respectively. Prior prostatectomy accounted for 92.3% of patients, and 46.2% had prior pelvic radiation. Postoperatively, 59.0% of patients were very satisfied; 64.1% of patients reported no difficulty of use; 53.8% felt confidence within 1 day; and 66.7% had much better bladder control. Average pad improvement count was 5.3. Pinch test was associated with satisfaction (P = .011) while peg test was associated with confidence (P = .049). Handshake and upper extremity questionnaire were not significant. CONCLUSION: The pinch and 9-hole peg transfer tests are cost-effective and easily performed adjuncts that could be used during artificial urinary sphincter evaluation for patients with unclear manual functional status.

How Effective Was the 2014 AUA Cryptorchidism Guideline? A Multi-institutional Evaluation.

INTRODUCTION: In 2014, the AUA published guidelines regarding the evaluation of cryptorchidism. This multi-institutional study aims to determine if these guidelines reduced the age of referral and the utilization of ultrasound in boys with cryptorchidism. We hypothesize that delayed referral continues, and utilization of ultrasound remains unchanged. METHODS: A retrospective review of boys referred for the evaluation of cryptorchidism was performed at 4 academic institutions, collecting data for 1 year prior (2013) and 2 nonconsecutive years following guideline creation (2015 and 2019). Across these time frames, we compared median ages at evaluation and surgery, and rates of patient comorbidities, orchiopexy, and preevaluation ultrasound. RESULTS: A total of 3,293 patients were included. The median age at initial pediatric urology evaluation in all cohorts was 39 months (IQR: 14-92 months). Following publication of the AUA Guidelines, there was no difference (P = .08) in the median age at first evaluation by a pediatric urologist between 2013 and 2015, and an increase (P = .03) between 2013 and 2019. Overall, 21.2% of patients received an ultrasound evaluation prior to referral, with no significant difference between 2013 and 2015 (P = .9) or 2019 (P = .5) cohorts. CONCLUSIONS: Our data suggest that, despite publication of the AUA Guidelines on evaluation and treatment of cryptorchidism, there has been no reduction in the age of urological evaluation or the utilization of imaging in boys with undescended testis. Finding alternative avenues to disseminate these evidence-based recommendations to referring providers and exploring barriers to guideline adherence is necessary to improve care for patients with cryptorchidism.

Exploring Factors Associated with Decisions about Feminizing Genitoplasty in Differences of Sex Development.

STUDY OBJECTIVE: Infants with genital development considered atypical for assigned female sex may undergo feminizing genitoplasty (clitoroplasty and/or vaginoplasty) in early life. We sought to identify factors associated with parent/caregiver decisions regarding genitoplasty for their children with genital virilization. DESIGN: Longitudinal, observational study SETTING: Twelve pediatric centers in the United States with multidisciplinary differences/disorders of sex development clinics, 2015-2020 PARTICIPANTS: Children under 2 years old with genital appearance atypical for female sex of rearing and their parents/caregivers INTERVENTIONS/OUTCOME MEASURES: Data on the child's diagnosis and anatomic characteristics before surgery were extracted from the medical record. Parents/caregivers completed questionnaires on psychosocial distress, experience of uncertainty, cosmetic appearance of their child's genitalia, and demographic characteristics. Urologists rated cosmetic appearance. For 58 patients from the study cohort with genital virilization being raised as girls or gender-neutral, we compared these data across 3 groups based on the child's subsequent surgical intervention: (i) no surgery (n = 5), (ii) vaginoplasty without clitoroplasty (V-only) (n = 15), and (iii) vaginoplasty and clitoroplasty (V+C) (n = 38). RESULTS: Fathers' and urologists' ratings of genital appearance were more favorable in the no-surgery group than in the V-only and V+C groups. Clitorophallic length was greater in the V+C group compared with the V-only group, with substantial overlap between groups. Mothers' depressive and anxious symptoms were lower in the no-surgery group compared with the V-only and V+C groups. CONCLUSIONS: Surgical decisions were associated with fathers' and urologists' ratings of genital appearance, the child's anatomic characteristics, and mothers' depressive and anxious symptoms. Further research on surgical decision-making is needed to inform counseling practices.

Role of the androgen, estrogen, and progesterone receptors in adherent perinephric fat in robotic partial nephrectomy.

To determine whether androgen, estrogen, and/or progesterone signaling play a role in the pathophysiology of adherent perinephric fat (APF). We prospectively recruited patients undergoing robotic assisted partial nephrectomy during 2015-2017. The operating surgeon documented the presence or absence of APF. For those with clear cell renal cell carcinoma (ccRCC), representative sections of tumor and perinephric fat were immunohistochemically stained with monoclonal antibody to estrogen α, progesterone, and androgen receptors. Patient characteristics, operative data, and hormone receptor presence were compared between those with and without APF. Of 51 patients total, 18 (35.3%) and 33 (64.7%) patients did and did not have APF, respectively. APF was associated with history of diabetes mellitus (61.1% vs 24.2%, p = 0.009) and larger tumors (4.0 cm vs 3.0 cm, p = 0.017) but not with age, gender, BMI, Charleston comorbidity index, smoking, or preoperative estimated glomerular filtration rate. APF was not significantly associated with length of operation, positive margins, or 30-day postoperative complications but incurred higher estimated blood loss (236.5 mL vs 209.2 mL, p = 0.049). Thirty-two had ccRCC and completed hormone receptor staining. The majority of tumors and perinephric fat were negative for estrogen and progesterone while positive for androgen receptor expression. There was no difference in hormone receptor expression in either tumor or perinephric fat when classified by presence or absence of APF (p > 0.05). APF is more commonly present in patients with diabetes or larger tumors but was not associated with differential sex hormone receptor expression in ccRCC.

Antibiotic Duration After Urethroplasty: An Attempt at Improving Antibiotic Stewardship.

OBJECTIVE: To evaluate if decreasing postop abx prophylaxis affects UTI and wound infection rates in patients following urethroplasty. METHODS: A retrospective review of patients who underwent urethroplasty from 9/2017 - 3/2020 by a single surgeon was performed. All patients received urine culture specific perioperative IV abx prior to urethroplasty and kept a urethral catheter for 3 weeks postop. Patients undergoing a urethroplasty from 9/2017 to 12/2018 received extended postop abx prophylaxis for 3 weeks until catheter removal (Group 1). Patients from 12/2018 to 3/2020 received abx for 3 days around catheter removal (Group 2). UTIs, abx complications, and wound infections between groups were evaluated. UTIs were defined as a positive urine culture or reported lower urinary tract symptoms/fevers treated with empiric abx. RESULTS: 120 patients underwent urethroplasty. Group 1 consisted of 60 patients with mean age of 51.9 years and mean stricture length of 3.6 cm. Group 2 had 60 patients with mean age of 53.1 years and mean stricture length of 3.8 cm. 10 patients had UTIs after urethroplasty. There was no significant difference in UTI (6.7% vs 11.7%; P = 0.529) or wound infection rates (3.3% vs 1.7%;' P = 1.000) between the two groups. CONCLUSION: Extended postoperative antibiotic prophylaxis does not appear to significantly affect UTI or wound infection rates following urethroplasty. The retrospective nature of the study has limitations, however, this is the first comparison of two different antibiotic administration protocols to our knowledge.

Contemporary Pure Laparoscopic vs Robot-Assisted Laparoscopic Radical Nephrectomy: Is the Transition Worth It?

Introduction: The proportion of robotic procedures continues to rise. The literature reinforces that robotic procedures take longer and are often more costly. We compared cost and perioperative outcomes of laparoscopic radical nephrectomy (LRN) and robot-assisted radical nephrectomy (RARN) at our high-volume center. Materials and Methods: We retrospectively reviewed our 2012-2015 data repository for patients undergoing RARN and LRN for a renal mass. Perioperative and oncologic outcomes were compared. We performed a multivariate analysis of operative time, estimated blood loss, length of stay (LOS), and overall and major 90-day complication rates while controlling for demographic data, Charlson comorbidity index (CCI), tumor size, and surgeon factors. We compared fixed, variable, and distinct procedural costs. Results: We identified 99 LRN and 95 RARN cases. There was no difference in demographic data, tumor size, preoperative renal function, and malignant histology. LRN patients had more comorbidities (49.5% vs 27.3% CCI 2+, p = 0.018). The mean preoperative glomerular filtration rate was higher in the robotic cohort (84.8 vs 75.1, p = 0.48). Mean operative time was 32.7 minutes longer (p = 0.002) and estimated blood loss 145 mL higher (p = 0.007) for the RARN cohort. There was no difference in mean LOS. Major and all 90-day complication rates were no different. The mean procedural cost for RARN was higher by $464 when controlling for operative time (p < 0.001). Fixed costs were not statistically different. Variable costs for RARN were estimated to be $2,310 higher (p = 0.045). Conclusions: Even with cost-conscious, experienced renal surgeons, RARN is associated with a longer procedure, higher supply costs, and higher hospitalization costs. There was no difference in positive surgical margin and complications. There were fewer 30-day readmissions for the RARN cohort, which may represent under-recognized cost savings. With fewer LRN cases in the United States each year, discussion to address cost is warranted. Without better outcomes for robotic surgery, a change in reimbursement to cover costs is unlikely to happen.

Post-operative complications following masculinizing genitoplasty in moderate to severe genital atypia: results from a multicenter, observational prospective cohort study.

INTRODUCTION: Differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. A phenotype of severe genital atypia in patients raised as male is a relatively rare occurrence and standards for management are lacking. Decision making for early surgical planning in these rare cases includes, but is not limited to, degree of atypia, location of testes, and presence of Mϋllerian remnants. In this study we describe surgical approaches and short-term outcomes for masculinizing genitoplasty in moderate to severe genital atypia in young patients raised male, for whom parents opted for early surgery. METHODS: This NIH-sponsored study is an ongoing, observational, multicenter investigation assessing medical, surgical and psychological outcomes in children and their parents affected by atypical genitalia due to DSD. Participants were prospectively enrolled from 12 children's hospitals across the United States that specialize in DSD care. Criteria for child enrollment were a Quigley score of 3-6 in those with a 46, XY or 45,X/46, XY chromosome complement, age <3 years with no previous genitoplasty; patients were included independent of whether genitoplasty was performed. Cosmesis was graded according to a 4-point Likert scale and complications per the Clavian-Dindo classification. RESULTS: Of the 31 participants, 30 underwent hypospadias repair and 1 patient did not undergo a genitoplasty procedure. The majority of participants (22) received a staged hypospadias repair. Seventeen complications were identified in 12 of the 31 children (41%) at 12 months of follow up. Glans dehiscence and urethrocutaneous fistula were the most common complications. Orchiopexy was performed in 14 (44%) and streak gonads were removed in 4 (13%) participants. Both parents and surgeons reported improved cosmesis after surgery when compared to baseline. CONCLUSION: Genitoplasty was chosen by parents for the majority of children eligible for study. No single surgical approach for masculinizing moderate to severe genital ambiguity in young patients with 46, XY or 45,X/46, XY DSD was adopted by all surgeons. Complications occurred in 41% of those who underwent genitoplasty for severe hypospadias. Overall, appearance of the genitals, as determined by parents and surgeons, improved following genitoplasty. Outcomes of early genitoplasty are needed to guide families when making decisions about such procedures for their young children.

Racial Comparison of Patients Undergoing Minimally Invasive Partial Nephrectomy for Renal Masses at a Large Volume Tertiary Center.

Introduction and Objective: African American (AA) race has been identified to have a higher incidence of chronic kidney disease (CKD) and worse renal cancer survival compared with Caucasian Americans (CA), irrespective of tumor size, pathologic type, and surgical procedure. We aimed to compare the outcomes between CA and AA patients undergoing minimally invasive partial nephrectomy (PN) at our high-volume center. Materials and Methods: We queried our PN data repository from 2007 to 2017. We identified 981 cases of PN (robotic n = 943 and laparoscopic n = 38), of which there were 852 CA and 129 AA patients. We compared age, sex, body mass index (BMI), operative time, estimated blood loss (EBL), nephrometry score, tumor size, pre- and postoperative estimated glomerular filtration rate (eGFR), length of stay, Charlson Comorbidity Index (CCI), tumor characteristics, and 30-day complication rate. We then estimated the overall survival and disease-specific survival. Results: Age, BMI, operative time, EBL, nephrometry score, tumor size, CCI, length of stay, and sex were not statistically different. The mean preoperative eGFR was higher in the AA cohort (91.4 mL/min/1.73 m2 vs 86.1 mL/min/1.73 m2, p = 0.007); however, at 1 year, there was no mean difference (76.8 mL/min/1.73 m2 vs 74.5 mL/min/1.73 m2, p = 0.428). There was a higher percentage of Fuhrman Grade 3/4 in the AA cohort (33.3% vs 22.5%, p = 0.044). The AA cohort had a 2.66 × higher incidence of papillary renal cell carcinoma (RCC) (34.9% vs 13.1%, p < 0.001) and unclassified RCC (3.9% vs 0.4%, p = 0.001). There was no difference in tumor stage (p = 0.260) or incidence of benign histology (15.3% vs 11.6%, p = 0.278). There were no differences in 30-day complications (p = 0.330). The median follow-up was 43.2 months. By using Kaplan-Meier curves, there was no observed difference in overall survival (p = 0.752) or disease-free survival (p = 0.403). Conclusions: Our cohort of AA and CA patients with intermediate follow-up showed no worse outcomes for CKD or survival when undergoing laparoscopic or robotic PN. For low-stage renal cancer, there was no difference in overall survival and disease-free survival at a median follow-up of 43.2 months among AA patients, despite having higher grade tumors and a higher percentage of unclassified RCC. Our cohort of AA patients did have a higher incidence of papillary RCC. The equivalent overall survival and disease-free survival could be due to the earlier discovery of lower stage renal masses incidentally identified on imaging studies performed equally for other reasons in both AA and CA patients.

Distress Trajectories for Parents of Children With DSD: A Growth Mixture Model.

OBJECTIVE: This study identifies trajectories of parent depressive symptoms after having a child born with genital atypia due to a disorder/difference of sex development (DSD) or congenital adrenal hyperplasia (CAH) and across the first year postgenitoplasty (for parents who opted for surgery) or postbaseline (for parents who elected against surgery for their child). Hypotheses for four trajectory classes were guided by parent distress patterns previously identified among other medical conditions. METHODS: Participants included 70 mothers and 50 fathers of 71 children diagnosed with a DSD or CAH with reported moderate to high genital atypia. Parents were recruited from 11 US DSD specialty clinics within 2 years of the child's birth and prior to genitoplasty. A growth mixture model (GMM) was conducted to identify classes of parent depressive symptoms over time. RESULTS: The best fitting model was a five-class linear GMM with freely estimated intercept variance. The classes identified were termed "Resilient," "Recovery," "Chronic," "Escalating," and "Elevated Partial Recovery." Four classes have previously been identified for other pediatric illnesses; however, a fifth class was also identified. The majority of parents were classified in the "Resilient" class (67.6%). CONCLUSIONS: This study provides new knowledge about the trajectories of depressive symptoms for parents of children with DSD. Future studies are needed to identify developmental, medical, or familial predictors of these trajectories.

Positive Surgical Margins After Robot-Assisted Partial Nephrectomy Predict Long-Term Oncologic Outcomes for Clinically Localized Renal Masses.

Introduction: For patients with clinically localized renal masses, positive surgical margins (PSMs) after robotic partial nephrectomy (RPN) have been associated with a higher risk of disease recurrence, although some studies have challenged this conclusion. Owing to inconsistent reports and a lack of long-term robotic data, the clinical impact of PSM after RPN remains uncertain. We evaluate long-term (>6 years) survival outcomes after RPN in patients with clinically localized disease with respect to surgical margin status. Methods: We conducted a retrospective review of patients who underwent RPN for clinically localized renal masses from June 2007 to December 2012 at Washington University School of Medicine. Disease recurrence and overall survival (OS) were stratified on the presence or absence of PSM. The cohort was analyzed to identify patient- and tumor-specific characteristics associated with PSM. Results: We identified 374 RPNs performed from 2007 to 2012 with a mean follow-up time of 77.7 months (SD 32.2 months). PSM was identified in 12 (3.2%) patients. Patients with PSM were at 14-fold increased risk for recurrence with no difference in OS (p < 0.001, p = 0.130, respectively). Patients with PSM had higher incidence of chronic obstructive pulmonary disease (COPD) (25% vs 6.4%) and greater blood loss (425 mL vs 203 mL). Conclusion: With an extended follow-up period of 77 months after RPN, we found that PSM substantially increased the risk of recurrence without impacting OS. Our finding that PSM may occur more frequently in older patients with COPD must be confirmed in larger studies.

Illness Uncertainty Longitudinally Predicts Distress Among Caregivers of Children Born With DSD.

OBJECTIVE: A subset of parents of children with disorders/differences of sex development (DSD) including ambiguous genitalia experience clinically elevated levels of anxious and depressive symptoms. Research indicates that uncertainty about their child's DSD is associated with parent psychosocial distress; however, previous studies have been cross-sectional or correlational in nature. The current study is the first to examine the longitudinal trajectory of the relationship between caregiver-perceived uncertainty about their child's DSD and caregiver anxious and depressive symptoms across the first 12 months following genital surgery in young children, or if surgery was not performed, the first 12 months following study entry. METHODS: One hundred and thirteen caregivers (Mage = 32.12; 57.5% mothers; 72.6% Caucasian) of children (N = 70; Mage = 9.81 months; 65.7% female) with DSD were recruited from 12 DSD specialty clinics in the United States. Caregivers completed psychosocial measures at baseline, 6 and 12 months following genitoplasty, or study entry if parents elected not to have surgery for their child. RESULTS: Caregiver illness uncertainty and both anxious and depressive symptoms were highest at baseline and decreased over time (ps < .05). Caregiver illness uncertainty predicted symptoms of anxious and depressive symptoms across all time points (ps < .05). CONCLUSIONS: Caregivers' perceptions of uncertainty about their child's DSD are highest soon after diagnosis, and uncertainty continues to predict both anxious and depressive symptoms across time. Thus, the initial diagnostic period is a critical time for psychological assessment and intervention, with parent illness uncertainty being an important clinical target.

Utility of a Pigtail Cope Loop Catheter for Bladder Drainage in Treating a Large/Persistent Urethrovesical Anastomotic Leak Following Radical Prostatectomy.

Background: A large or persistent urethrovesical anastomotic leakage after a laparoscopic or robot-assisted laparoscopic radical prostatectomy (RALRP) although infrequent can be a difficult complication to treat. We describe a simple technique to facilitate resolution of a urethrovesical anastomotic leak by exchanging the in-place bladder Foley catheter for a pigtail drainage catheter. Case Presentation: Between 2014 and 2019, we had three patients who had a large/persistent urine leak after a radical prostatectomy (one laparoscopic and two robot assisted). All three patients had a wide bladder neck requiring bladder neck reconstruction with ureteral orifices close to the anastomosis. The bladder Foley catheter was exchanged to a pigtail Cope loop catheter™ (14F) or an Origin™ self-retaining drainage catheter (16F) under flexible cystoscopic guidance over a guidewire. Placement of a Cope loop bladder catheter stopped anastomotic leakage expeditiously with no need for further intervention. At minimum 3 months follow-up none had bladder neck stricture with 0-1 pad urinary incontinence. Conclusion: Drainage of the bladder through the use of a loop pigtail nephrostomy catheter can be useful in rapidly resolving a large persistent urethrovesical anastomotic leak.

Post-operative complications following feminizing genitoplasty in moderate to severe genital atypia: Results from a multicenter, observational prospective cohort study.

Disorders/differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. While there remains controversy around the traditionally binary concept of sex, most patients with DSD are reared either male or female depending on their genetic sex, gonadal sex, genital phenotype and status of their internal genital tract. This study uses prospective data from 12 institutions across the United States that specialize in DSD care. We focused on patients raised female. Eligible patients had moderate to severe genital atypia (defined as Prader score >2), were ≤2 years of age at entry, and had no prior genitoplasty. The aim of this study is to describe early post operative complications for young patients undergoing modern approaches to feminizing genitoplasty. Of the 91 participants in the cohort, 57 (62%) were reared female. The majority had congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (n = 52), 1 had ovo-testicular syndrome, 2 had mixed gonadal dysgenesis and 2 had partial androgen insensitivity syndrome (PAIS). Of the 50 participants who received early genitoplasty, 43 (86%) had follow-up at 6-12 months post-surgery. Thirty-two participants (64%) received a clitoroplasty, 31 (62%) partial urogenital mobilization and 4 (8%) total urogenital sinus mobilization. Eighteen percent (9/50) experienced post-surgical complications with 7 (14%) being rated as Clavien-Dindo grade III. Both parents and surgeons reported improved satisfaction with genital appearance of participants following surgery compared to baseline. This information on post-operative complications associated with contemporary approaches to feminizing genitoplasty performed in young children will help guide families when making decisions about whether or not to proceed with surgery for female patients with moderate to severe genital atypia.

Pediatric cystoscopy of male urethral strictures: an accurate and useful preoperative surgical decision making tool.

INTRODUCTION: To evaluate flexible pediatric cystoscopy (FPC) as an adjunctive procedure to retrograde urethrography (RUG) and voiding cystourethrography (VCUG) in the preoperative setting for male urethral strictures. Since imaging interpretation of stricture length and caliber can be difficult at times, we sought to evaluate diagnostic utility of FPC to predict reconstructive surgery. MATERIALS AND METHODS: Reconstructive urology databases at Washington University and Columbia University were queried from 2010-2017. A total of 185 anterior urethroplasty patients met inclusion criteria. All surgeries were performed by a single surgeon. There were 102 patients that underwent preoperative FPC (7.5 Fr in diameter). Surgical urethroplasty techniques employed were: ventral or dorsal onlay buccal mucosa graft, fasciocutaneous penile skin flap, excision and primary anastomosis or augmented anastomotic. We analyzed the RUG, VCUG, FPC, and intraoperative details of the urethral strictures by univariate and multivariate statistics. RESULTS: Mean patient age was 47.2 (+/-16.5) years. Of the patients who underwent FPC, 42.2% were narrower than the FPC, and 57.8% were wider. Intraoperative stricture length better correlated with FPC findings compared to RUG/ VCUG (r = 0.834 versus r = 0.766) (p < 0.001). Moreover, inability to pass the FPC through the stricture correlated with the need to perform urethral stricture excision or complete reconstruction of the urethral plate (p = 0.005), rather than onlay urethroplasty. CONCLUSION: Preoperative FPC is a useful adjunctive tool in the evaluation of urethral strictures. FPC facilitates stricture assessment by accurately correlating with intraoperative stricture length and predicting the need to excise or graft during reconstruction.

Predictors of Psychosocial Distress in Parents of Young Children with Disorders of Sex Development.

PURPOSE: We evaluated demographic, financial and support predictors of distress for parents of young children with disorders of sex development including atypical genital development, and characterized early parental experiences. This work extends our previous findings to identify those parents at risk for distress. MATERIALS AND METHODS: Participants included mothers (76) and fathers (63) of a child (78) diagnosed with disorders of sex development characterized by moderate to severe genital atypia. Parents completed a demographic questionnaire, measures of anxious and depressive symptoms, quality of life, illness uncertainty and posttraumatic stress symptoms, and rated their satisfaction with the appearance of their child's genitalia. RESULTS: Depressive and posttraumatic stress symptoms of caregivers were comparable to standardized norms while levels of anxious symptoms were below norms. A subset of parents reported clinically elevated symptoms. Overall 26% of parents reported anxious symptoms, 24% reported depressive symptoms and 17% reported posttraumatic stress symptoms. Levels of illness uncertainty were lower than those of parents of children with other chronic illnesses. Differences by parent sex emerged, with mothers reporting greater distress. Lower income, increased medical care and travel expenses, and having no other children were related to increased psychosocial distress. CONCLUSIONS: Early psychosocial screening is recommended for parents of children with disorders of sex development. Clinicians should be aware that financial burden and lack of previous parenting experience are risk factors for distress.

Clustering of Patients with Interstitial Cystitis/Bladder Pain Syndrome and Chronic Prostatitis/Chronic Pelvic Pain Syndrome.

PURPOSE: We performed clustering analysis of patient symptoms to discover common patient subtypes in females and males with interstitial cystitis/bladder pain syndrome or chronic prostatitis/chronic pelvic pain syndrome. MATERIALS AND METHODS: The clinical variables included in k-means clustering were urological pain severity, urinary urgency, frequency and nonurological pain, each on a 0 to 10 numerical rating scale, and a yes or no response to each of the 6 UPOINT (Urological Treatment Program for Chronic Prostatitis) domains, including the urinary, psychosocial, organ specific, infection, neurological/systemic and skeletal muscle tenderness domains. RESULTS: Included in study were 211 patients seeking care of interstitial cystitis/bladder pain syndrome or chronic prostatitis/chronic pelvic pain syndrome. The k-means clustering algorithm identified 3 clusters of patients with interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome, including 1) a mild pelvic symptom cluster in about 30% of patients, 2) a severe pelvic symptom cluster in about 40% and 3) a systemic symptom cluster in about 30%. Patients in the systemic cluster were younger by about 5 to 7 years and more likely to be female. They had the most severe urinary symptoms (urgency, frequency and painful bladder filling), and the most severe pelvic and nonpelvic pain. They were also more likely to have chronic overlapping pain conditions, psychosocial issues (depression, anxiety and somatic symptoms) and poorer quality of life than patients in the 2 other pelvic clusters. They were not less likely to have Hunner lesions in the bladder. CONCLUSIONS: Symptom based clustering identified 3 clusters of patients with interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome. These patient subtypes had different pelvic and systemic presentations. Patients in the systemic cluster may benefit from interdisciplinary therapies. Future studies are needed to elucidate differences in pathophysiology among these clusters.

Comparing Off-clamp and On-clamp Robot-assisted Partial Nephrectomy: A Prospective Randomized Trial.

OBJECTIVE: To determine whether performing robot-assisted partial nephrectomy without warm ischemia "off-clamp" results in favorable postoperative renal functional outcomes compared with the on-clamp method. METHODS: We conducted a prospective trial of 80 patients who underwent robot-assisted partial nephrectomy. They were randomized in a 1:1 ratio to undergo the procedure with renal artery clamping or without clamping. The groups were compared across demographics, operative information, perioperative outcomes, and postoperative renal function. We assessed renal function by estimated glomerular filtration rate and renal scintigraphy both preoperatively and at 3 months postoperatively. RESULTS: Patients in the on-clamp and off-clamp groups were similar in age, gender, body mass index, comorbidities, clinical tumor size, nephrometry score, and laterality. Off-clamp procedures were lengthier at an average 178.0 minutes vs 156.0 minutes for on-clamp (P = .011). Estimated blood loss, rates of pelvicalyceal repair, postoperative complications, and positive margins were not different. At a median 3-month follow-up, no significant differences were seen in change in postoperative estimated glomerular filtration rate or percent split renal function between both groups. CONCLUSION: In this prospective study, off-clamp robot-assisted partial nephrectomy resulted in similar perioperative outcomes compared with the on-clamp technique. No benefit was demonstrated in the preservation of renal function. Urologists may safely employ either an on-clamp or off-clamp strategy depending on surgeon preference and patient-specific factors including baseline renal insufficiency, multiple masses, or solitary kidney.

Unplanned 30-Day Encounters After Ureterorenoscopy for Urolithiasis.

OBJECTIVE: To identify avoidable predictors of postureteroscopy (URS) unplanned encounters and to minimize 30-day encounters. MATERIALS AND METHODS: We performed retrospective chart review and telephone surveys on patients who underwent URS for urolithiasis between January and June 2016. Univariate and multivariable analyses evaluated for potential predictors of unplanned encounters. RESULTS: Of 157 patients, there were 44 (28.0%) unplanned patient-initiated clinical phone calls, 23 (14.6%) emergency department (ED) visits, and 8 (5.1%) readmissions, with pain being the most common complaint during the encounters. Factors associated with a higher rate of phone calls include first-time stone procedure (36.6% vs 20.9%, p = 0.029), outpatient status (30.3% vs 0%, p = 0.021), intraoperative stent placement (31.2% vs 0%, p = 0.006), and stent removal at home (58.8% vs 28.8%, p = 0.014). Factors associated with increased rate of ED visits were first-time stone procedure (22.5% vs 8.1%, p = 0.011) and ureteral access sheath (UAS) usage (29.6% vs 11.8%, p = 0.018). Factors associated with a higher rate of readmissions were lower body mass index (23.9 vs 29.7, p = 0.013), bilateral procedure (20.0% vs 2.9%, p = 0.010), and UAS usage (14.8% vs 3.1%, p = 0.032). Stone burden, operative time, Charlson comorbidity index, and preoperative urinary tract infection were not significantly associated with postoperative encounters. CONCLUSIONS: Pain, first-time stone treatment, presence of a ureteral stent, outpatient status, bilateral procedures, and UAS usage were common reasons for postoperative encounters after URS. Appropriate perioperative patient education and counseling and adequate pain management may minimize these encounters and improve treatment quality and patient satisfaction.

Superior metastasis-free survival for patients with high-risk prostate cancer treated with definitive radiation therapy compared to radical prostatectomy: A propensity score-matched analysis.

PURPOSE: For high-risk prostate cancer (HR-PCa) in men with a life expectancy of at least 10 years, the National Comprehensive Cancer Network recommends radiation therapy (RT) plus androgen deprivation therapy (ADT) with category 1 evidence or radical prostatectomy (RP) as an acceptable initial therapy. Randomized evidence regarding which therapy is optimal for disease control is lacking for men with HR-PCa. We performed a propensity-score-matched comparison of outcomes for men with localized HR-PCa treated with primary RT or RP. METHODS AND MATERIALS: The medical records of patients with localized HR-PCa who were treated at our institution between 2002 and 2011 were reviewed. Patient and disease characteristics, treatment details, and outcomes were collected. A combination of nearest-neighbor propensity score matching on age, Adult Comorbidity Evaluation-27 comorbidity index, prostate-specific antigen, biopsy Gleason scores, and clinical T-stage as well as exact matching on prostate-specific antigen, biopsy Gleason scores, and clinical T-stage was performed. Outcomes were measured from diagnosis. Multivariate Cox proportional hazards regression was used to compare metastasis-free and overall survival. RESULTS: A total of 246 patients were identified with 62 propensity-score-matched pairs. ADT was administered to 6.5% and 80.6% of patients receiving RP and RT, respectively. Five-year rates of metastasis for RP and RT were 33% and 8.9%, respectively (P = .003). Overall survival was not different. Delay of salvage therapy was longer for patients undergoing primary RT (P < .001). Findings were similar when only those patients who did not receive ADT were compared. CONCLUSIONS: At our institution, treatment with primary RT resulted in superior metastasis-free survival over RP. This was not accompanied by an improvement in OS.

Psychological Adjustment of Parents of Children Born with Atypical Genitalia 1 Year after Genitoplasty.

PURPOSE: We examined the psychological adjustment of parents of children born with moderate to severe genital atypia 12 months after their child underwent genitoplasty. MATERIALS AND METHODS: Parents were recruited longitudinally from a multicenter collaboration of 10 pediatric hospitals with specialty care for children with disorders/differences of sex development and/or congenital adrenal hyperplasia. Parents completed measures of depressive and anxious symptoms, illness uncertainty, quality of life, posttraumatic stress and decisional regret. RESULTS: Compared to levels of distress at baseline (before genitoplasty) and 6 months after genitoplasty, data from 25 mothers and 20 fathers indicated significant improvements in all psychological distress variables. However, a subset of parents continued endorsing clinically relevant distress. Some level of decisional regret was endorsed by 28% of parents, although the specific decision that caused regret was not specified. CONCLUSIONS: Overall the majority of parents were coping well 1 year after their child underwent genitoplasty. Level of decisional regret was related to having a bachelor's level of education, increased levels of illness uncertainty preoperatively and persistent illness uncertainty at 12 months after genitoplasty but was unrelated to postoperative complications.
