RESUMO

We report a rare case of a 56-year-old Ukrainian female with inflammatory breast cancer (IBC) who underwent neoadjuvant chemoradiation and left radical mastectomy with her clinical course complicated by disease recurrence with bone and bladder metastases 2.5 years after her initial diagnosis. We highlight the presentation and diagnosis of genitourinary involvement of metastatic IBC, which has not previously been described in the literature.

RESUMO

We sought to evaluate the impact of Oxycodone prescriptions on short-term patient outcomes and long-term Oxycodone use following inflatable penile prosthesis (IPP) placement. We queried the TriNetX research database for all adult patients undergoing IPP. Cohorts included opioid naïve patients prescribed postoperative Oxycodone against propensity score-matched patients without a prescription. We compared return visits to the emergency department (ED) within 14 and 90 days of surgery, a diagnosis of opioid abuse or dependence disorder 6 months or later after surgery and persistent Oxycodone use 9-15 months after surgery. After matching, there were 2433 patients in each group. There was an increase in 90-day ED visits based on receipt of Oxycodone (6.8% of patients vs 5.0%, risk ratio (RR) 1.4 95% confidence interval (CI) [1.1, 1.7]). Groups had similar 14-day ED visits (3.7% of patients vs 2.9%, RR 1.3, 95% CI [0.95, 1.7]). Patients prescribed Oxycodone (5.1% of patients vs 2.7%, RR 1.9, 95% CI [1.4, 2.6]) were more likely to have persistent Oxycodone use at 9-15 months. There were low instances of diagnosis of opioid dependence or abuse for both groups limiting comparison. Oxycodone prescription after IPP has risks of persistent use and withholding Oxycodone does not appear to increase postoperative healthcare utilization.

RESUMO

Background: Artificial urinary sphincters (AUS) are the gold standard treatment for patients with stress urinary incontinence. However, risk factors for implant infection, complication, or re-intervention (removal, repair, replacement) are incompletely understood. We sought to understand the impact of various patient factors on the risk of device failure by leveraging a large, multi-national research database. Methods: We queried the TriNetX database for all adult patients undergoing AUS. We evaluated the impact of age, body mass index, race, ethnicity, diabetes (DM), smoking history, history of radiation therapy (RT), history of radical prostatectomy (RP) and history of urethroplasty on select clinical outcomes. Our primary outcome was the need for re-intervention defined by current procedural terminology (CPT) codes. Secondary outcomes included overall device complication rate and infection rate defined by international classification of diseases (ICD) codes. Analytics were performed on TriNetX which calculated risk ratios (RR) and Kaplan-Meier (KM) survival. We evaluated our outcomes first on the entire population and then repeated analyses for each individual comparison cohort using the remaining demographic variables to perform propensity score matching (PSM). Results: The overall rates of AUS re-intervention, complication and infection were 23.4%, 24.1% and 6.4%, respectively. KM analysis showed median AUS survival (no need for re-intervention) at 10.6 years and projected 20-year survival probability at 31.3%. Patients with a history of smoking or urethroplasty were at higher risk of AUS complication and re-intervention. Patients with DM or a history of RT were at higher risk of AUS infection. Patients with a history of RT were at higher risk of AUS complication. All risk factors besides race showed a difference in device removal itself. Conclusions: To our knowledge, this represents the largest series to follow patients with an AUS. About one-quarter of AUS patients needed re-intervention. Multiple demographics place patients at increased risk of re-intervention, infection, or complication. These results can help guide patient selection and counseling with the goal of reducing complications.

RESUMO

Background and Objective: Stress urinary incontinence (SUI) can occur due to a variety of etiologies. For male patients specifically, SUI is typically thought of as iatrogenic secondary to intrinsic sphincter deficiency occurring after prostate surgery. Given the noted negative impact that SUI can have on a man's quality of life, multiple treatment options have been developed to improve symptoms. However, there is no "One-Size-Fits-All" approach to management of male SUI. In this narrative review, we sought to highlight some of the various procedures and devices available to treat men with bothersome SUI. Methods: This narrative review gathered primary resources through Medline search, and secondary resources by cross-referencing citations used in articles of interest. We started our investigation by searching for previous systematic reviews on male SUI and treatments for male SUI. Furthermore, we reviewed societal guidelines, such as the American Urological Association and Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction guidelines and the recently published European Urological Association guidelines. Our review focused on English-language full-length manuscripts when available. Key Content and Findings: We present multiple surgical options for men with SUI. This review focuses on surgical options including 5 fixed male slings, 3 adjustable male slings, 4 artificial urinary sphincters (AUS), and an adjustable balloon device. This review includes treatment options from across the globe, although not all included devices are available in the United States. Conclusions: A great variety of treatment options exist for men with SUI, although not all Federal Drug Administration (FDA) approved. Shared decision making is paramount to generate the greatest satisfaction for patients.

RESUMO

We report a rare case of a 56-year-old male with a history of hypertension who initially presented to the emergency department with abdominal pain and was radiologically diagnosed with left xanthogranulomatous pyelonephritis (XGP) in a non-functioning kidney with a staghorn calculus. Pathological evaluation of his kidney revealed squamous cell carcinoma (SCC) of the renal pelvis with invasion into the renal parenchyma. We highlight the presentation, diagnosis, and management of this rare condition.

RESUMO

OBJECTIVE: To understand whether patients taking sodium-glucose co-transporter 2 inhibitors (SGLT2i) would be at a similar risk of genitourinary device infection or failure as patients not taking these medications. METHODS: We queried the TriNetX database for all adult male patients undergoing artificial urinary sphincter (AUS) or inflatable penile prosthesis (IPP) and compared patients taking SGLT2i against those not. Cohorts and outcomes were defined using current procedural terminology and International Classification of Diseases (ICD-10) codes. We used Age, body mass index, diabetes, smoking history and history of prostatectomy to generate propensity score matching. Our primary outcome was need for reintervention after implantation based on current procedural terminology codes. Secondary outcomes included infection rate and overall complication rate based on ICD-10 codes. Analytics were performed via TriNetX which calculated risk ratios. RESULTS: Analyses were run on November 28, 2022. After propensity score matching, there were 319 and 83 patients in each IPP and AUS cohort and comorbidity profiles were similar. Patients with an IPP on an SGLT2i were at a lower risk of overall complication (10.6% vs 16.1%, RR 0.66, P = .049). There was similar rates for AUS and risk of complication and for either implant on risk of infection or reintervention. CONCLUSION: Patients taking SGLT2is may be safely offered urologic implants. Patients taking an SGLT2 had a lower risk of complication for IPP, and there were similar rates of infection and reintervention for both IPP and AUS.

RESUMO

INTRODUCTION: Hemorrhagic cystitis (HC) is a morbid condition for patients and can be challenging for urologists to manage. There are many potential contributing etiologies and the severity of bleeding can be variable. It is important to consider each clinical scenario when formulating management strategies in order to provide the highest quality of care to patients. We provide a review of the literature including diagnosis and treatment options. MATERIALS AND METHODS: We performed a literature search on PubMed using the following keywords: hemorrhagic cystitis, cystitis, gross hematuria, intractable hematuria. We considered all available published articles with no specific inclusion or exclusion criteria for the purposes of this review. RESULTS: We reviewed a total of 41 articles and identified a broad differential diagnosis for intractable hemorrhagic cystitis including infection, chemical exposure, malignancy, nephropathy, trauma, radiation therapy, and idiopathic etiology. Depending on the severity of bleeding, many treatments have been described. These range from conservative strategies (bladder fulguration and continuous irrigation) to more extreme and morbid therapies (intravesical instillations, embolization, and urinary diversion). CONCLUSION: Hemorrhagic cystitis is a relatively common and can be a difficult condition to manage for urologists. It is important to understand the etiology and available treatments options in order to best treat our patients. We provide a comprehensive and thorough review of the literature and propose a stepwise treatment approach.

RESUMO

INTRODUCTION: Urinary Tract Infection (UTI) has been cited as the primary cause of morbidity in patients with history of spinal cord injury (SCI). Despite the significance of recurrent UTI (rUTI) in this population, the causative physiologic and patient characteristics are not well described. We sought to assess associations between demographic, clinical and urodynamic variables and rUTI. MATERIALS AND METHODS: The records of 136 individuals with SCI who perform clean intermittent catheterization (CIC) were retrospectively reviewed. All had a video urodynamics study (VUDS) available for analysis. Individuals were divided into non-recurrent (< 3/year) or rUTI (≥ 3/year) groups. Differences between the cohorts were analyzed. Multivariable logistic regression was performed to determine associations between various demographic, clinical, and VUDS variables and rUTI. RESULTS: Self-reported rUTI were noted in 58 of 136 individuals. Of 124 individuals with urinary culture results, African American race (43.3% vs. 22.3%) and 'Other' race (13.3% vs. 8.5%) made up larger proportions in the rUTI group. Female gender (OR 4.96, 95% CI [1.44-17.13]) and African American race (OR 5.16, 95% CI [1.80-14.79]) were increasingly associated with rUTI on multivariable logistic regression. Shorter interval since injury was also significantly associated with recurrent infections with each year since injury indicating diminished likelihood (OR 0.91, 95% CI [0.82-0.99]). There were no significant differences in VUDS variables between groups and none were significant on regression as potential determinants of rUTI. CONCLUSIONS: Patient race, gender, and time since SCI appear to have significant associations with rUTI in individuals with SCI using CIC. However, VUDS variables were not found to be significantly associated with rUTI.

RESUMO

Purpose: Prostate cancer primarily arises from the glandular epithelium. Histomophometric techniques have been used to assess the glandular epithelium in automated detection and classification pipelines; however, they are often rigid in their implementation, and their performance suffers on large datasets where variation in staining, imaging, and preparation is difficult to control. The purpose of this study is to quantify performance of a pixelwise segmentation algorithm that was trained using different combinations of weak and strong stroma, epithelium, and lumen labels in a prostate histology dataset. Approach: We have combined weakly labeled datasets generated using simple morphometric techniques and high-quality labeled datasets from human observers in prostate biopsy cores to train a convolutional neural network for use in whole mount prostate labeling pipelines. With trained networks, we characterize pixelwise segmentation of stromal, epithelium, and lumen (SEL) regions on both biopsy core and whole-mount H&E-stained tissue. Results: We provide evidence that by simply training a deep learning algorithm on weakly labeled data generated from rigid morphometric methods, we can improve the robustness of classification over the morphometric methods used to train the classifier. Conclusions: We show that not only does our approach of combining weak and strong labels for training the CNN improve qualitative SEL labeling within tissue but also the deep learning generated labels are superior for cancer classification in a higher-order algorithm over the morphometrically derived labels it was trained on.

RESUMO

Prostate cancer is the most common noncutaneous cancer in men in the United States. The current paradigm for screening and diagnosis is imperfect, with relatively low specificity, high cost, and high morbidity. This study aims to generate new image contrasts by learning a distribution of unique image signatures associated with prostate cancer. In total, 48 patients were prospectively recruited for this institutional review board-approved study. Patients underwent multiparametric magnetic resonance imaging 2 weeks before surgery. Postsurgical tissues were annotated by a pathologist and aligned to the in vivo imaging. Radiomic profiles were generated by linearly combining 4 image contrasts (T2, apparent diffusion coefficient [ADC] 0-1000, ADC 50-2000, and dynamic contrast-enhanced) segmented using global thresholds. The distribution of radiomic profiles in high-grade cancer, low-grade cancer, and normal tissues was recorded, and the generated probability values were applied to a naive test set. The resulting Gleason probability maps were stable regardless of training cohort, functioned independent of prostate zone, and outperformed conventional clinical imaging (area under the curve [AUC] = 0.79). Extensive overlap was seen in the most common image signatures associated with high- and low-grade cancer, indicating that low- and high-grade tumors present similarly on conventional imaging.

RESUMO

BACKGROUND: Human papillomavirus is a common sexually transmitted infection that may affect the oropharynx, genitalia, or anus. Some strains of this virus may cause bulky growths around the anus known as giant anal condylomas. These can become large, disfiguring, and may cause bleeding, as well as difficulty with defecation and hygiene. Surgical management is usually necessary for large condylomas, whereas office-based procedures are common for smaller lesions. It is unclear why some develop large anal margin tumors, whereas others develop limited disease. The aim of the present study was to evaluate for risk factors that may play a role in the development of extensive disease warranting operative management. MATERIALS AND METHODS: A retrospective chart review of patients seen within the Anal Dysplasia Clinic at the Medical College of Wisconsin was undertaken. Clinic encounters for patients with anogenital condyloma were abstracted for demographic information, operative interventions, Human Immunodeficiency Virus status, and smoking history to determine risk factors that predicted operative intervention for giant anal condylomas. RESULTS: A total of 239 patients met inclusion criteria; 211 (88.3%) were male and 28 (11.7%) were female. Racial makeup of the cohort included 49% Caucasian, 38.9% African-American, 9.2% Hispanic, and 2.9% were identified as another ethnicity. One hundred forty-three patients (60.1%) were current or past smokers. One hundred ninety-eight (82.8%) patients tested positive for human immunodeficiency virus (HIV), whereas 41 (17.2%) were negative. Multiple linear regression identified only African-American race as predictive of greater disease burden. CONCLUSIONS: African-American race was associated with increased size of anal condyloma. As the size of anal condylomas increase, management shifts from topical treatments to operative intervention. This is the first study to correlate race with burden of disease in the general population.
