Evaluating limited biopsy templates for men with markedly elevated PSAs.

INTRODUCTION: To define the smallest prostate needle biopsy (PNB) template necessary for accurate tissue diagnosis in men with markedly elevated PSA while decreasing procedural morbidity. MATERIALS AND METHODS: We performed a chart review of 80 men presenting with a newly elevated PSA > 100 ng/mL who underwent biopsy (PNB or metastatic site). For patients who underwent a full 12-core biopsy, simulated templates of 2- to 10-cores were generated by randomly drawing subsets of biopsies from their full-template findings. Templates were iterated to randomize core location and generate theoretical smaller template outcomes. Simulated biopsy results were compared to full-template findings to determine accuracy to maximal Grade Group (GG) diagnosis. RESULTS: Amongst those that underwent PNB, 93% had GG 4 or 5 disease. Twenty-two (40%) underwent a full 12-core biopsy, 20 (37%) a 6-core biopsy, and only 8 (15%) had fewer than six biopsy cores sampled at our hospital. Simulated templates with 2-, 4-, 6-, and 8-cores correctly diagnosed prostate cancer in all patients, and accurately identified the maximal GG in 82%, 91%, 95%, and 97% of patients, respectively. The biopsy locations most likely to detect maximal GG were medial mid and base sites bilaterally. A 4-core template of these sites would have accurately detected the maximal GG in 95% of patients relative to a full 12-core template. CONCLUSIONS: In men presenting with PSA > 100 ng/mL, decreasing from a 12-core to a 4-core prostate biopsy template results in universal cancer detection and minimal under-grading while theoretically decreasing procedural morbidity and cost.

Racial Disparities in Outcomes of Women Undergoing Myomectomy.

OBJECTIVE: To assess the association of racial and socioeconomic factors with outcomes of abdominal myomectomies. METHODS: All women undergoing abdominal myomectomy in California from 2005 to 2012 were identified from the OSHPD (Office of Statewide Health Planning and Development) using appropriate International Classification of Diseases and Current Procedural Terminology codes. Demographics, comorbidities, surgical approaches, and complications occurring within 30 days of the procedure were identified. Multivariate associations were assessed with mixed effects logistic regression models. RESULTS: The cohort of 35,151 women was racially and ethnically diverse (White, 38.8%; Black, 19.9%; Hispanic, 20.3%; and Asian, 15.3%). Among all procedures, 33,906 were performed through an open abdominal approach, and 1,245 were performed using a minimally invasive approach. Proportionally, Black patients were more likely than White patients to have open procedures, and open approaches were associated with higher complication rates. Overall, 2,622 (7.5%) women suffered at least one complication. Although severe complications did not vary by race or ethnicity, Black (9.0%), Hispanic (7.9%), and Asian (7.5%) patients were more likely to suffer complications of any severity compared with White patients (6.7%, P<.001). As compared with patients with private insurance (6.4%), those with indigent payer status (Medicaid [12.1%] and self-pay [11.1%]) had higher complication rates (P<.001). Controlling for all factors, Black and Asian patients were more likely to suffer complications compared with White patients. CONCLUSION: The overall complication rate after abdominal myomectomy was 7.5%. Comorbidities, an open approach, and indigent payer status were associated with increased complication risk. Controlling for all factors, Black and Asian patients still had increased risks of complications.

Evaluation of Patient Treatment Preferences for 15 to 20 mm Kidney Stones: A Conjoint Analysis.

Introduction and Objective: Ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) are standard treatments for intermediate-size (15-20 mm) kidney stones but differ in their postoperative recovery, stone-free rates, and complication risks. We aimed to evaluate what affects patient treatment preferences. Methods: Patients with urinary stone disease completed a choice-based conjoint analysis exercise assessing four treatment attributes associated with URS and PCNL. A sensitivity analysis using a market simulator was performed, and the relative importance of each attribute was calculated. Differences in treatment preferences by demographic subgroup were assessed. Results: A total of 58 patients completed the conjoint analysis exercise. Stone-free rate was the most important treatment attribute, while the length of hospital stay and cosmesis were less important. Overall, sensitivity analysis based on market simulation scenarios predicted an almost equal preference for URS (52.4%) compared with PCNL (47.6%) for treatment of an intermediate-size stone. Older patients (>65 years old) expressed their stronger preferences for lower infection rates and shorter hospital stays, and were more likely to prefer URS (67.2%, 95% confidence interval [CI]: 52% to 82.5%) compared with younger patients (20-34 years old) (20.3%, 95% CI: 0% to 41.5%) who preferred higher procedure success rates and fewer repeat procedures. Conclusion: Conjoint analysis predicts nearly equal patient preference for URS or PCNL for the treatment of intermediate-size kidney stones. Older patients prefer the lower urinary tract infection risk and shorter hospital stay associated with URS, while younger patients prefer higher stone-free rates associated with PCNL. These results can help guide urologists in counseling patients and improve the shared decision-making process.

Predictors of Colpocleisis Outcomes in an Older Population Based Cohort.

PURPOSE: Colpocleisis is an obliterative surgical option for women with pelvic organ prolapse that is often performed in a frail population. However, because outcomes remain largely unknown we aimed to assess the durability and perioperative safety of colpocleisis in a large population based cohort. MATERIALS AND METHODS: All women undergoing colpocleisis and other pelvic organ prolapse repairs in California (2005-2011) were identified using the Office of Statewide Health Planning and Development data sets. Durability was defined as the absence of future pelvic organ prolapse repair after index repair for the duration of the data sets. Thirty-day morbidity was assessed by identifying readmissions, repeat surgeries and complications. A metric to assess frailty in large administrative databases was applied to assess the impact of frailty on outcomes. Colpocleisis outcomes were compared to other types of pelvic organ prolapse repairs by developing propensity score matched groups. RESULTS: Among the 2,707 women undergoing colpocleisis, reoperation for prolapse occurred in 47 (1.8%). At least 1 complication occurred in 11.1% of the cohort, with serious complications occurring in 2%. Frail patients were more likely to experience any complication (23.3% vs 10.3%, p <0.01) and a serious complication (5.0% vs 1.8%, p=0.02) and was the best predictor of morbidity. Colpocleisis was associated with a more durable repair (overall failure 1.8% vs 3.5%, p <0.01) with no difference in complication rates as compared to the matched cohort. CONCLUSIONS: Colpocleisis provides a more durable outcome than reconstructive pelvic organ prolapse repairs without increased perioperative morbidity. Frailty is a better predictor than age for perioperative complications after colpocleisis.

Female Urethral Stricture Management: The Initial Experience of an Female Pelvic Medicine and Reconstructive Surgery-Trained Urologist.

OBJECTIVE: Given the rarity of female urethral strictures (the cause of <1% of female lower urinary tract symptoms), most trainees have little experience diagnosing and managing the problem as they begin practice. Presented are the female urethral stricture outcomes of an attending surgeon after the completion of a female pelvic medicine and reconstructive surgery fellowship. METHODS: With institutional review board approval, a retrospective review of all cases of suspected female urethral stricture through the first 7 years of practice was completed. RESULTS: Over the study period, 13 women were treated for urethral stricture. One underwent simple meatotomy, 9 underwent vaginal wall flap (Blandy) urethroplasty, and 3 underwent urethral dilation only because they were not reconstructive candidates (1 due to severe radiation damage and 2 with panurethral strictures that included the bladder neck). Women undergoing urethral dilations (n = 3) have all required subsequent dilations, whereas those undergoing reconstructive procedures have not required further intervention (all with max flow rates greater than 17 mL/s at last follow-up [median = 35 months, range = 10-70]). CONCLUSION: Over the course of 7 years, our limited experience suggests that (a) urethral dilation is not usually successful but surgical reconstruction is, (b) preoperative urethral rest before reconstruction may reduce failure rates, (c) staging a stricture in the operating room is the best route to confirm the diagnosis, (d) de novo stress urinary incontinence seems to rarely if ever occur after female urethroplasty, and (e) postoperative follow-up with simple uroflow and postvoid residual testing suffices.

Treatment of urethral stricture disease in women: A multi-institutional collaborative project from the SUFU research network.

AIM: Female urethral stricture disease is rare and has several surgical approaches including endoscopic dilations (ENDO), urethroplasty with local vaginal tissue flap (ULT) or urethroplasty with free graft (UFG). This study aims to describe the contemporary management of female urethral stricture disease and to evaluate the outcomes of these three surgical approaches. METHODS: This is a multi-institutional, retrospective cohort study evaluating operative treatment for female urethral stricture. Surgeries were grouped into three categories: ENDO, ULT, and UFG. Time from surgery to stricture recurrence by surgery type was analyzed using a Kaplan-Meier time to event analysis. To adjust for confounders, a Cox proportional hazard model was fit for time to stricture recurrence. RESULTS: Two-hundred and ten patients met the inclusion criteria across 23 sites. Overall, 64% (n = 115/180) of women remained recurrence free at median follow-up of 14.6 months (IQR, 3-37). In unadjusted analysis, recurrence-free rates differed between surgery categories with 68% ENDO, 77% UFG and 83% ULT patients being recurrence free at 12 months. In the Cox model, recurrence rates also differed between surgery categories; women undergoing ULT and UFG having had 66% and 49% less risk of recurrence, respectively, compared to those undergoing ENDO. When comparing ULT to UFG directly, there was no significant difference of recurrence. CONCLUSION: This retrospective multi-institutional study of female urethral stricture demonstrates that patients undergoing endoscopic management have a higher risk of recurrence compared to those undergoing either urethroplasty with local flap or free graft.

Contemporary multicenter outcomes of continent cutaneous ileocecocystoplasty in the adult population over a 10-year period: A Neurogenic Bladder Research Group study.

AIMS: Evidence is sparse on the long-term outcomes of continent cutaneous ileocecocystoplasty (CCIC). We hypothesized that obesity, laparoscopic/robotic approach, and concomitant surgeries would affect morbidity after CCIC and aimed to evaluate the outcomes of CCIC in adults in a multicenter contemporary study. METHODS: We retrospectively reviewed the charts of adult patients from sites in the Neurogenic Bladder Research Group undergoing CCIC (2007-2017) who had at least 6 months of follow-up. We evaluated patient demographics, surgical details, 90-day complications, and follow-up surgeries. the Mann-Whitney U test was used to compare continuous variables and χ² and Fisher's Exact tests were used to compare categorical variables. RESULTS: We included 114 patients with a median age of 41 years. The median postoperative length of stay was 8 days. At 3 months postoperatively, major complications occurred in 18 (15.8%), and 24 patients (21.1%) were readmitted. During a median follow-up of 40 months, 48 patients (42.1%) underwent 80 additional related surgeries. Twenty-three patients (20.2%) underwent at least one channel revision, most often due to obstruction (15, 13.2%) or incontinence (4, 3.5%). Of the channel revisions, 10 (8.8%) were major and 14 (12.3%) were minor. Eleven patients (9.6%) abandoned the catheterizable channel during the follow-up period. Obesity and laparoscopic/robotic surgical approach did not affect outcomes, though concomitant surgery was associated with a higher rate of follow-up surgeries. CONCLUSIONS: In this contemporary multicenter series evaluating CCIC, we found that the short-term major complication rate was low, but many patients require follow-up surgeries, mostly related to the catheterizable channel.

Balancing the possibility of needing a future incontinence procedure versus a future urethral sling revision surgery: a tradeoff analysis for continent women undergoing pelvic organ prolapse surgery.

INTRODUCTION AND HYPOTHESIS: Although urinary incontinence surgery has potential benefits such as preventing de novo stress urinary incontinence in women undergoing pelvic organ prolapse (POP) surgery, it comes with the potential cost of overtreatment and complications. We compared future surgery rates in a population cohort of women undergoing vaginal pelvic organ prolapse surgery. METHODS: All women undergoing POP repair in California from 2005 to 2011 were identified from the Office of Statewide Health Planning and Development databases. Rates of repeat surgery in those with and without concomitant urethral sling procedures were compared. To control for confounding effects, multivariate mixed effects logistic regression models were constructed to compare each woman's individualized risk of undergoing either sling revision surgery or future incontinence surgery. RESULTS: In the cohort, 38,456 underwent a sling procedure at the time of POP repair and 42,858 did not. The future surgery rate was higher for sling-related complications in the POP + sling cohort compared with future incontinence surgery in the POP alone cohort (3.5% versus 3.0% respectively, p < 0.001). The difference persisted in multivariate modeling, where most women (60%) are at a higher risk of requiring sling revision surgery compared with needing a future primary incontinence procedure (40%). CONCLUSIONS: Women who undergo vaginal prolapse repair without an incontinence procedure are at a low risk of future incontinence surgery. Women without urinary incontinence who are considering vaginal POP surgery should be informed of the risks and benefits of including a sling procedure.

Implantation of Sacral Nerve Stimulator Without Rhizotomy for Neurogenic Bladder in Patient With Spinal Cord Injury: 2-Dimensional Operative Video.

There are approximately 12 000 new individuals with spinal cord injury (SCI) each year, and close to 200 000 individuals live with a SCI-related disability in the United States. The majority of patients with SCI have bladder dysfunction as a result of their injury, with over 75% unable to void volitionally following their injury. In patients with traumatic SCI, intermittent catheterization is commonly recommended, but a lack of adherence to clean intermittent catheterization (CIC) has been observed, with up to 50% discontinuing CIC within 5 yr of injury. The Finetech Brindley Bladder System (FBBS) is an implantable sacral nerve stimulator for improving bladder function in patients with SCI, avoiding the need for CIC. The FDA-approved implantation (Humanitarian Device Exemption H980008) of the FBBS is combined with a posterior rhizotomy to reduce reflex contraction of the bladder, improving continence. However, the posterior rhizotomy is irreversible and has unwanted effects; therefore, the current FDA-approved implantation is being studied without rhizotomy as part of a clinical trial (Investigational Device Exemption G150201) (ClinicalTrials.gov Identifier: NCT02978638). In this video, we present a case of a 66-yr-old female who presented 40-yr status post-T12 SCI, resulting in complete paraplegia and neurogenic bladder not satisfactorily controlled with CIC. We demonstrate the operative steps to complete the implantation of the device without rhizotomy in the first patient enrolled as part of the clinical trial Electrical Stimulation for Continence After SCI (NCT02978638). Appropriate IRB and patient consent were obtained.

Reoperation rates for pelvic organ prolapse repairs with biologic and synthetic grafts in a large population-based cohort.

INTRODUCTION AND HYPOTHESIS: As the long-term complications of synthetic mesh become increasingly apparent, re-evaluation of alternative graft options for pelvic organ prolapse (POP) repairs is critical. We sought to compare the long-term reoperation rates of biologic and synthetic grafts in POP repair. METHODS: Using the California Office of Statewide Health Planning and Development database, we identified all women who underwent index inpatient POP repair with either a synthetic or biologic graft between 2005 and 2011 in the state of California. ICD-9 and CPT codes were used to identify subsequent surgeries in these patients for either recurrent POP or a graft complication. RESULTS: A total of 14,192 women underwent POP repair with a biologic (14%) or synthetic graft (86%) during the study period. Women with biologic grafts had increased rates of surgery for recurrent pelvic organ prolapse (3.6% vs 2.5%, p = 0.01), whereas women with synthetic grafts had higher rates of repeat surgery for a graft complication (3.0 vs 2.0%, p = 0.02). There were no significant differences between the overall risk of repeat surgery between the groups (5.7% vs 5.6%, p = 0.79). These effects persisted in multivariate modeling. CONCLUSIONS: We demonstrate in a large population-based cohort that biologic grafts are associated with an increased rate of repeat surgery for POP recurrence whereas synthetic mesh is associated with an increased rate of repeat surgery for a graft complication. These competing risks result in an equivalent overall any-cause repeat surgery rate between the groups. These data suggest that neither type of graft should be excluded from use and encourage a personalized risk assessment.

Statewide Success of Staged Sacral Neuromodulation for the Treatment of Urinary Complaints in California (2005-2011).

PURPOSE: Sacral neuromodulation (SNS) is approved by the Food and Drug Administration as a third-line treatment for refractory overactive bladder, idiopathic urinary retention, and fecal incontinence. Prior to implantation of an implantable pulse generator, all patients undergo a trial phase to ensure symptom improvement. The published success rates of progression from the test phase to permanent implant vary widely (range, 24% to >90%). We sought to characterize success rates using a statewide registry. METHODS: Using nonpublic data, we identified SNS procedures using the California Office of Statewide Planning and Development ambulatory surgery database from 2005 to 2011. A successful trial was defined as receiving a stage 2 generator implantation after trial lead placement. Multivariable logistic regression was performed to identify factors associated with staged success. RESULTS: During the study period, 1396 patients underwent a staged SNS procedure, with 962 (69%) subsequently undergoing generator placement. Successful trial rates were 72% for overactive bladder wet, 69% for urgency/frequency, 68% for interstitial cystitis, 67% for neurogenic bladder, and 57% for urinary retention. On multivariate logistic regression, only male sex (odds ratio, 0.51) and urinary retention [odds ratio, 0.54) were significantly associated with lower odds of success, whereas age, race/ethnicity, medical insurance, and placement at an academic or high-volume institution had no association. CONCLUSIONS: The "real world" success rates for staged SNS implantation in California are less than those observed by some academic centers of excellence but better than previously reported for Medicare beneficiaries. Successful trial rates for interstitial cystitis and neurogenic voiding dysfunction are similar to refractory overactive bladder.

Twenty-Four Hour Urine Testing and Prescriptions for Urinary Stone Disease-Related Medications in Veterans.

BACKGROUND AND OBJECTIVES: Current guidelines recommend 24-hour urine testing in the evaluation and treatment of persons with high-risk urinary stone disease. However, how much clinicians use information from 24-hour urine testing to guide secondary prevention strategies is unknown. We sought to determine the degree to which clinicians initiate or continue stone disease-related medications in response to 24-hour urine testing. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We examined a national cohort of 130,489 patients with incident urinary stone disease in the Veterans Health Administration between 2007 and 2013 to determine whether prescription patterns for thiazide diuretics, alkali therapy, and allopurinol changed in response to 24-hour urine testing. RESULTS: Stone formers who completed 24-hour urine testing (n=17,303; 13%) were significantly more likely to be prescribed thiazide diuretics, alkali therapy, and allopurinol compared with those who did not complete a 24-hour urine test (n=113,186; 87%). Prescription of thiazide diuretics increased in patients with hypercalciuria (9% absolute increase if urine calcium 201-400 mg/d; 21% absolute increase if urine calcium >400 mg/d, P<0.001). Prescription of alkali therapy increased in patients with hypocitraturia (24% absolute increase if urine citrate 201-400 mg/d; 34% absolute increase if urine citrate ≤200 mg/d, P<0.001). Prescription of allopurinol increased in patients with hyperuricosuria (18% absolute increase if urine uric acid >800 mg/d, P<0.001). Patients who had visited both a urologist and a nephrologist within 6 months of 24-hour urine testing were more likely to have been prescribed stone-related medications than patients who visited one, the other, or neither. CONCLUSIONS: Clinicians adjust their treatment regimens in response to 24-hour urine testing by increasing the prescription of medications thought to reduce risk for urinary stone disease. Most patients who might benefit from targeted medications remain untreated.

Urologic Injury and Fistula After Hysterectomy for Benign Indications.

OBJECTIVE: To explore the rates and risk factors for sustaining a genitourinary injury during hysterectomy for benign indications. METHODS: In this population-based cohort study, all women who underwent hysterectomy for benign indications were identified from the Office of Statewide Health Planning and Development databases in California (2005-2011). Genitourinary injuries were further classified as identified at the time of hysterectomy, identified after the date of hysterectomy; or unidentified until a fistula developed. RESULTS: Of the 296,130 women undergoing hysterectomy for benign indications, there were 2,817 (1.0%) ureteral injuries, 2,058 (0.7%) bladder injuries and 834 (0.3%) genitourinary fistulas (80/834 of which developed after an injury repair). Diagnosis was delayed in 18.6% and 5.5% of ureteral and bladder injuries, respectively. Subsequent genitourinary fistula development was lower if the injury was identified immediately (compared with delayed) for both ureteral (0.7% vs 3.4% odds ratio [OR] 0.28; 95% CI 0.14-0.57) and bladder injuries (2.5% vs 6.5% OR 0.37; 95% CI 0.16-0.83). Indwelling ureteral stent placement alone was more successful in decreasing the risk of a second ureteral repair for immediately recognized ureteral injuries (99.0% vs 39.8% for delayed injuries). With multivariate adjustment, prolapse repair (OR 1.44, 95% CI 1.30-1.58), an incontinence procedure (OR 1.40, 95% CI 1.21-1.61), mesh augmented prolapse repair (OR 1.55, 95% CI 1.31-1.83), diagnosis of endometriosis (OR 1.46, 95% CI 1.36-1.56), and surgery at a facility in the bottom quartile of hysterectomy volume (OR 1.37, 95% CI 1.01-1.89) were all associated with an increased likelihood of a genitourinary injury. An exclusively vaginal (OR 0.56, 95% CI 0.53-0.64) or laparoscopic (OR 0.80, 95% CI 0.75-0.86) approach was associated with lower risk of a genitourinary injury as compared with an abdominal approach. CONCLUSION: Genitourinary injury occurs in 1.8% of hysterectomies for benign indications; immediate identification and repair is associated with a reduced risk of subsequent genitourinary fistula formation.

To stage or not to stage?-A cost minimization analysis of sacral neuromodulation placement strategies.

AIMS: Sacral neuromodulation (SNM) is a standard therapy for refractory overactive bladder (OAB). Traditionally, SNM placement involves placement of an S3 lead with 1-3 weeks of testing before considering a permanent implant. Given the potential risk of bacterial contamination during testing and high success rates published by some experts, we compared the costs of traditional 2-stage against single-stage SNM placement for OAB. METHODS: We performed a cost minimization analysis using published data on 2-stage SNM success rates, SNM infection rates, and direct reimbursements from Medicare for 2017. We compared the costs associated with a 2-stage vs single-stage approach. We performed sensitivity analyses of the primary variables listed above to assess where threshold values occurred and used separate models for freestanding ambulatory surgery centers (ASC) and outpatient hospital departments (OHD). RESULTS: Based on published literature, our base case assumed a 69% SNM success rate, a 5% 2-stage approach infection rate, a 1.7% single-stage approach infection rate, and removal of 50% of non-working single-stage SNMs. In both ASC ($17 613 vs $18 194) and OHD ($19 832 vs $21 181) settings, single-stage SNM placement was less costly than 2-stage placement. The minimum SNM success rates to achieve savings with a single-stage approach occur at 65.4% and 61.3% for ASC and OHD, respectively. CONCLUSIONS: Using Medicare reimbursement, single-stage SNM placement is likely to be less costly than 2-stage placement for most practitioners. The savings are tied to SNM success rates and reimbursement rates, with reduced costs up to $5014 per case in centers of excellence (≥ 90% success).

Do appreciable changes in the upper extremity motor capability to perform clean intermittent catheterization come about with time after traumatic spinal cord injury?

INTRODUCTION: Bladder dysfunction after spinal cord injury (SCI) often requires clean intermittent catheterization (CIC) or other management strategies. A common dilemma in those desiring to perform CIC independently but lacking the appropriate upper extremity (UE) motor function is the timing of reconstructive surgery. METHODS: We assessed the National Spinal Cord Injury Data Set for the years 2000-2016. Our cohort consisted of persons with cervical SCI, who underwent complete motor examination upon discharge from rehabilitation and at 1-year follow-up. Using a previously published algorithm, UE motor scores were transformed to predict a patient's ability to independently perform CIC. Improvements in the predicted ability to self-catheterize were evaluated. RESULTS: Of the 1428 individuals meeting the inclusion criteria, improvements in the predicted UE motor function necessary to independently self-catheterize were observed in 39%, 42%, and 38% of those deemed possibly able, only able with surgical assistance, or unable to self-catheterize at rehabilitation discharge, respectively. On multivariate analysis, only increasing Association Impairment Scale (AIS) classification and AIS classification improvement over the first year were associated with an increased odds of improving predicted CIC ability (odds ratio [OR] = 1.44 for AIS C and 1.97 for AIS D compared with AIS A, and OR = 1.90 for AIS classification improvement versus stable AIS classification, P < 0.05 for each). CONCLUSION: Improvements in UE motor function to independently perform CIC occur in approximately 40% of persons with cervical SCI in the first year after rehabilitation discharge. Those with incomplete injuries are more likely to improve. These findings should enhance patient bladder management counseling and guide surgeons in determining an appropriate timeline for offering reconstruction.

Percutaneous Nephroureteral Tube: A Useful Tool for Management of Intractable Hematuria.

OBJECTIVE: To describe our experience using percutaneous nephroureteral (PCNU) tube placement for the management of intractable gross hematuria. METHODS: We identified patients at our institution who underwent PCNU tube placement from August 2011 to October 2017 for management of gross hematuria who had previously failed management with manual irrigation, continuous bladder irrigation, and cystoscopy with clot evacuation. The primary outcome measured was cessation of bleeding obviating the need for further blood transfusion in a 30 day follow-up period. RESULTS: Six patients were treated with PCNU tube placement for intractable hematuria from either malignant or nonmalignant etiologies. In all patients after PCNU tube placement, hematocrit value remained stable, there were no further transfusions requirements within 30 days, and no immediate or periprocedural complications were encountered. In no instance did a PCNU become obstructed by blood clots and in all cases the bladder and both kidneys were adequately drained. CONCLUSION: In patients with hematuria refractory to conventional management techniques, the placement of a PCNU tube allows for cessation of bleeding, successfully diverts urine with no immediate complications and is not subsequent to clot obstruction of the tube. The use of PCNU tube is a viable treatment in the algorithm of intractable hematuria, specifically before resorting to more morbid and potentially irreversible treatments.

Payer Type, Race/Ethnicity, and the Timing of Surgical Management of Urinary Stone Disease.

PURPOSE: Surgery for upper tract urinary stone disease is often reserved for symptomatic patients and those whose stone does not spontaneously pass after a trial of passage. Our objective was to determine whether payer type or race/ethnicity is associated with the timeliness of kidney stone surgery. MATERIALS AND METHODS: A population-based cohort study was conducted using the California Office of Statewide Health Planning and Development dataset from 2010 to 2012. We identified patients who were discharged from an emergency department (ED) with a stone diagnosis and who subsequently underwent a stone surgery. Primary outcome was time from ED discharge to urinary stone surgery in days. Secondary outcomes included potential harms resulting from delayed stone surgery. RESULTS: Over the study period, 15,193 patients met the inclusion criteria. Median time from ED discharge to stone surgery was 28 days. On multivariable analysis patients with Medicaid, Medicare, and self-pay coverage experienced adjusted mean increases of 46%, 42%, and 60% in time to surgery, respectively, when compared with those with private insurance. In addition, patients of Black and Hispanic race/ethnicity, respectively, experienced adjusted mean increases of 36% and 20% in time to surgery relative to their White counterparts. Before a stone surgery, underinsured patients were more likely to revisit an ED three or more times, undergo two or more CT imaging studies, and receive upper urinary tract decompression. CONCLUSIONS: Underinsured and minority patients are more likely to experience a longer time to stone surgery after presenting to an ED and experience potential harm from this delay.

Rates and Risk Factors for Future Stress Urinary Incontinence Surgery after Pelvic Organ Prolapse Repair in a Large Population-based Cohort in California.

OBJECTIVES: To determine the rate and risk factors for future stress urinary incontinence (SUI) surgery in a large population-based cohort of previously continent women following pelvic organ prolapse (POP) repair without concomitant SUI treatment. METHODS: Data from the Office of Statewide Health Planning and Development were used to identify all women who underwent anterior, apical, or combined anteroapical POP repair without concomitant SUI procedures in the state of California between 2005 and 2011 with at least 1-year follow-up. Patient and surgical characteristics were explored for associations with subsequent SUI procedures. RESULTS: Of 41,689 women undergoing anterior or apical POP surgery, 1,504 (3.6%) underwent subsequent SUI surgery with a mean follow-up time of 4.1 years. Age (odds ratio [OR] 1.01), obesity (OR 1.98), use of mesh at the time of POP repair (OR 2.04), diabetes mellitus (OR 1.19), white race, and combined anteroapical repair (OR 1.30) were associated with increased odds of future SUI surgery. CONCLUSION: The rate of subsequent surgery for de novo SUI following POP repair on a population level is low. Patient and surgical characteristics may alter a woman's individual risk and should be considered in surgical planning.

Burch Colposuspension.

The Burch colposuspension has a 50-plus year history demonstrating strong long-term outcomes with minimal complications. Iterations of the procedure, including laparoscopic, robotic, and mini-incisional approaches, appear to have equal efficacy to the open procedure. Although the current use of the Burch colposuspension has waned with the growing shift toward sling surgery, it continues to have a role in the treatment of stress urinary incontinence. Specifically, a Burch procedure should be considered when vaginal access is limited, concurrent intra-abdominal surgery is planned, or mesh is contraindicated.

Crowdsourced Assessment of Ureteroscopy with Laser Lithotripsy Video Feed Does Not Correlate with Trainee Experience.

OBJECTIVES: We sought to validate the use of crowdsourced surgical video assessment in the evaluation of urology residents performing flexible ureteroscopic laser lithotripsy. METHODS: We collected video feeds from 30 intrarenal ureteroscopic laser lithotripsy cases where residents, postgraduate year (PGY) two through six, handled the ureteroscope. The video feeds were annotated to represent overall performance and to contain parts of the procedure being scored. Videos were submitted to a commercially available surgical video evaluation platform (Crowd-Sourced Assessment of Technical Skills). We used a validated ureteroscopic laser lithotripsy global assessment tool that was modified to include only those domains that could be evaluated on the captured video. Videos were evaluated by crowd workers recruited using Amazon's Mechanical Turk platform as well as five endourology-trained experts. Mean scores were calculated and intraclass correlation coefficients (ICCs) were computed for the expert domain and total scores. ICCs were estimated using a linear mixed-effects model. Spearman rank correlation coefficients were calculated as a measure of the strength of the relationships between the crowd mean and expert average scores. RESULTS: A total of 30 videos were reviewed 2488 times by 487 crowd workers and five expert endourologists. ICCs between expert raters were all below accepted levels of correlation (0.30), with the overall score having an ICC of <0.001. For individual domains, the crowd scores did not correlate with expert scores, except for the stone retrieval domain (0.60 p = 0.015). In addition, crowdsourced scores had a negative correlation with the PGY level (0.44, p = 0.019). CONCLUSIONS: There is poor agreement between experts and poor correlation between expert and crowd scores when evaluating video feeds of ureteroscopic laser lithotripsy. The use of an intraoperative video of ureteroscopy with laser lithotripsy for assessment of resident trainee skills does not appear reliable. This is further supported by the lack of correlation between crowd scores and advancing PGY level.
