Case presentation and review of renal autotransplantation for nutcracker syndrome.

Nutcracker Syndrome (NCS) is characterized by entrapment of the left renal vein, leading hematuria, flank pain, and proteinuria. We evaluated the efficacy of renal autotransplantation as a curative treatment for NCS through a review and case report. 55 patients from 18 studies were analyzed, with a combined 91% success rate of symptom resolution or improvement post-autotransplantation. In our case report, a 25-year-old man with severe NCS received laparoscopic nephrectomy and autotransplant, resulting in symptom resolution at 3.1 years follow up. Further research should confirm these findings and refine patient selection criteria and surgical techniques.

Potential energy surfaces and dynamic properties via ab initio composite and density functional approaches.

Vibrational spectroscopy enables critical insight into the structural and dynamic properties of molecules. Presently, the majority of theoretical approaches to spectroscopy employ wavefunction-based ab initio or density functional methods that rely on the harmonic approximation. This approximation breaks down for large molecules with strongly anharmonic bonds or for molecules with large internuclear separations. An alternative to these methods involves generating molecular anharmonic potential energy surfaces (potentials) and using them to extrapolate the vibrational frequencies. This study examines the efficacy of density functional theory (DFT) and the correlation consistent Composite Approach (ccCA) in generating anharmonic frequencies from potentials of small main group molecules. Vibrational self-consistent field Theory (VSCF) and post-VSCF methods were used to calculate the fundamental frequencies of these molecules from their potentials. Functional choice, basis set selection, and mode-coupling are also examined as factors in influencing accuracy. The absolute deviations for the calculated frequencies using potentials at the ccCA level of theory were lower than the potentials at the DFT level. With DFT resulting in bending modes that are better described than those of ccCA, a multilevel DFT:ccCA approach where DFT potentials are used for single vibrational mode potentials and ccCA is used for vibrational mode-mode couplings can be utilized for larger polyatomic systems. The frequencies obtained with this multilevel approach using VCIPSI-PT2 were closer to experimental frequencies than the scaled harmonic frequencies, indicating the success of utilizing post-VSCF methods to generate more accurate representations of computed infrared spectra.

Who Progresses to Third-Line Therapies for Overactive Bladder? Trends From the AQUA Registry.

INTRODUCTION: Overactive bladder (OAB) patients who do not achieve satisfactory results with second-line OAB medications should be offered third-line therapies (percutaneous tibial nerve stimulation, sacral neuromodulation, onabotulinumtoxinA bladder injection [BTX-A]). We aimed to determine which clinical factors affect progression from second- to third-line OAB therapy. METHODS: Between 2014 and 2020, the AUA Quality Registry was queried for adult patients with idiopathic OAB. For the primary outcome, patient and provider factors associated with increased odds of progression from second- to third-line therapy were assessed. Secondary outcomes included median time for progression to third-line therapy and third-line therapy utilization across subgroups. RESULTS: A total of 641,122 patients met inclusion criteria and were included in analysis. Of these, only 7487 (1.2%) received third-line therapy after receiving second-line therapy. On multivariate analysis, patients aged 65 to 79, women, White race, history of dual anticholinergic and ß3 agonist therapy, metropolitan area, government insurance, and single specialty practice had the greatest odds of progressing to third-line therapy. Black and Asian race, male gender, and rural setting had lower odds of progressing to third-line therapy. BTX-A was the most common therapy overall (40% BTX-A, 32% sacral neuromodulation, 28% percutaneous tibial nerve stimulation). The median time of progression from second- to third-line therapy was 15.4 months (IQR 5.9, 32.4). Patients < 50 years old and women progressed fastest to third-line therapy. CONCLUSIONS: Very few patients received third-line therapies, and the time to progression from second- to third-line therapies is > 1 year. The study findings highlight a potential need to improve third-line therapy implementation.

Factors Influencing Medication Selection for Management of Overactive Bladder: Trends and Insights From AUA Quality Registry.

OBJECTIVE: To determine how a patient's demographics, including insurance type, race/ethnicity, gender, and age, may impact the choice of medication prescribed for overactive bladder (OAB). METHODS: We queried the AUA Quality Registry for adults between 2014 and 2020 with a diagnosis of OAB for >1year, excluding neurogenic causes. Variables included age, race/ethnicity, gender, insurance type, medication first prescribed, year of prescription, provider metropolitan status, and provider practice type. Primary outcome was which factors were associated with increased odds of beta-3 prescription as first medication choice. RESULTS: We found 1,453,566 patients with OAB, 641,122 (44.1%) with complete data. Of these, 112,021 (17.5%) were prescribed medication. On multivariate analysis, patients with Medicaid, Medicare, and other/self-pay insurance were less likely to receive a beta-3 vs an anticholinergic compared to private or military insurance. Compared to white patients, Asian, Black, and other races were less likely to receive a beta-3, as were patients outside of metropolitan areas. Age >50, prescriptions after 2014, and nonacademic settings were associated with increased odds of beta-3 prescription. There was no difference between genders. CONCLUSION: Many nonclinical factors, including insurance type and race, may affect which medication is first prescribed for OAB. This is useful for practicing urologists and may help lower barriers to beta-3 prescription through policy change and advocacy.

Voided volume may not impact stone outcomes: Review of a large institutional nephrolithiasis cohort.

Background: Urologic guidelines universally recommend increasing fluid intake for kidney stone prevention. Increased voided volume is thought to help reduce stone recurrence and severity, but supporting evidence is limited. Patients and Methods: Nephrolithiasis outcomes and 24-h urine data for patients from the Registry for Stones of the Kidney and Ureter (ReSKU), a registry of nephrolithiasis patients collected between 2015 and 2020, were retrospectively analysed. Outcome was stone events, either an office visit where a patient reports symptomatic passage of stones or surgery for stone removal. Results: We identified 450 stone patients with 24-h urine and kidney stone outcome data. There was no significant difference in 24-h voided volume between patients with one stone event and patients with two or more stone events. On multivariable logistic regression, after controlling for age, gender, BMI, and 24-h sodium and creatinine per kilogram, no significant associations were found between voided volume and stone events. There was a statistically significant negative correlation noted between voided volume and stone events in calcium oxalate dihydrate stone formers (Spearman R = -0.42, p = 0.04), but not others. Conclusions: Twenty-four-hour voided volume was not associated with stone events in a large institutional cohort, and subset analysis reveals that some stone formers may benefit more from increased voided volume than others; identifying such patients represents a novel precision medicine opportunity.

A Novel Standardized Morbidity and Mortality Process to Promote Discourse, Improve Education, and Facilitate Practice Change: The M-PROVE Model.

INTRODUCTION: The morbidity and mortality conference is essential to medical education and quality improvement. Ideally, the conference is inclusive, judgment-free, and focused on practice improvement. In reality, it may not meet these goals. We reimagined the process by standardizing presentations and creating an oversight committee to improve the perceived value of the conference and identify opportunities for improvement. This study evaluates the subjective impact of the redesigned process at our institution and provides a blueprint for our reproducible model. METHODS: We created a faculty and resident committee to review all submitted cases, implemented a standardized presentation template and moderating structure, and tracked quality improvement measures from proposed improvement initiatives. Attitudes toward the conference, including perceived quality/relevance, identification of potential systems changes, inclusiveness, and educational value, were assessed among faculty and trainees using pre- and postintervention Likert-style surveys. RESULTS: Of 45 eligible department members, 41 (91%) completed the preintervention and 36 (80%) completed the postintervention survey. We found a statistically significant improvement in all questions between pre- and postintervention surveys except on the question about the conference environment being nonthreatening, which also improved but was not statistically significant. The overall average answer improved on the postintervention survey compared to the preintervention survey (3.36 vs 4.20, P < .001). These trends were similar regardless of attendee role and gender. CONCLUSIONS: Redesigning and standardizing the morbidity and mortality conference with greater attention to education, inclusion, systems change, and quality improvement improves the attitudes of conference attendees and increases the perceived value of the conference.

Herpes simplex virus-2 associated with a large fungating penile mass.

A 48-year-old male with HIV/AIDS presented with an enlarging nodular lesion on the base of his penis. Histology revealed changes consistent with chronic viral infection and culture grew herpes simplex virus 2 (HSV-2). The lesion was refractory to valacyclovir and intralesional (IL) cidofovir therapy. Urology excised the mass and the defect was repaired primarily with good cosmetic result. Post-operative pathology confirmed HSV-2 despite the unusual appearance of the lesion consisting of nodular mass without gross ulceration.

Traumatic testicular rupture: Multimodality imaging with intraoperative correlate.

Traumatic testicular rupture is a rare yet serious condition most commonly seen in penetrating trauma victims (e.g. gunshot wounds or motorcycle collisions) that requires immediate surgical management given its potential complications of hypogonadism and infertility. While ultrasound is the most established modality for diagnosing testicular rupture, trauma patients are usually first evaluated with a trauma protocol computed tomography (CT) exam including the chest, abdomen, and pelvis upon presentation, so it is important to recognize CT findings of testicular injury. We present a novel case in which the suspicion for testicular injury was initially raised based upon CT findings of scrotal hematoma/fluid. These findings were then further characterized with ultrasound and confirmed at surgery. In this case, we provide intraoperative imaging that corresponds clearly to findings seen on both CT and ultrasound.

Older and wiser? Changes in unprofessional content on urologists' social media after transition from residency to practice.

OBJECTIVE: To characterize changes in the frequency and nature of unprofessional content on urologists' Facebook accounts during the transition from residency to practice. METHODS: Facebook was queried with the names of all 2015 US urology graduates 1 year after completion of residency. We identified unprofessional and potentially objectionable content on the public Facebook accounts using a rubric based on professionalism guidelines by the American Urological Association, the American Medical Association and the Accreditation Council for Graduate Medical Education. Comparisons of unprofessional content were made with data from this cohort collected at the completion of residency. To assess how professional identities were reflected on social media, we determined which urologists self-identified as a urologist on Facebook and any changes in their unprofessional content. RESULTS: Of 281 urologists, 198 (70%) had publicly identifiable Facebook accounts. Of these, 85 (43%) contained any unprofessional or potentially objectionable content, including 35 (18%) with explicitly unprofessional content. Examples included images of and references to intoxication, explicit profanity, and offensive comments about patients. Of the 201 Facebook accounts that had been publicly identifiable at the completion of residency, most profiles (182, 91%) had remained public; of the 19 that were no longer public, about half had previously contained unprofessional content. Similarly, of the 80 urologists without public profiles 1 year previously, most (64, 80%) had remained unidentifiable on Facebook; of the 16 accounts that had since become publicly identifiable, half had unprofessional content. Among the urologists on Facebook overall, 11 (6%) had posted new unprofessional or potentially objectionable content since entering practice. Comparing this cohort in practice vs at the completion of residency, there were no significant differences in how many urologists had public Facebook accounts (70% vs 71%) or whose accounts had concerning content (43% vs 40%). The presence of unprofessional content at the completion of residency strongly predicted having unprofessional content later in practice. More urologists overall self-identified as being a urologist on Facebook, and a larger proportion of these profiles also displayed unprofessional content (53% vs 47% 1 year previously). CONCLUSION: Most urologists maintained public Facebook accounts after the transition to practice, and about half of these contained unprofessional or potentially objectionable content. Amidst their increasing self-identification as urologists on social media, the majority of practising urologists had posted concerning content, which could have an impact on their professional identities and public perceptions of the specialty.

Acquired hemophilia presenting as gross hematuria following kidney stone - a case report and review of the literature

ABSTRACT A rare condition in itself, acquired hemophilia A, seldom presents as isolated gross hematuria. It is a serious condition with a high mortality rate and thus clinical suspicion followed by prompt diagnosis is imperative (1). In fact, only 8 cases of such presentation of this condition have been reported thus far in the literature. Of these, none describe the initial presentation of hematuria with the inciting event of a kidney stone. We present a case of a 67-year-old man with signs and symptoms of nephrolithiasis accompanied by profuse hematuria, who was subsequently found to have developed expression of factor VIII inhibitor leading to acquired hemophilia A.
