Abstract Introduction: In the past, positron emission tomography (PET) has played a relatively limited role in prostate cancer imaging. However, in recent years, several new PET tracers have emerged, offering potential improvements in diagnostic performance for both the detection of prostate cancer metastases at initial staging and the localization of recurrent disease.
Materials and methods: We reviewed the literature for prostate cancer PET tracers that are either being used for patient management or being evaluated in clinical research trials. For each tracer, we compiled clinically relevant background information and evidence supporting clinical use, with the intention of providing… More >

Abstract Introduction: Abdominal wall hematoma (AWH) is a self-resolving, yet common complication from the insertion of trocars during laparoscopic surgery. Particularly, its appearance may increase patient anxiety and may reduce overall surgical satisfaction.
Materials and methods: In a retrospective study analyzing data from 724 robot-assisted radical prostatectomy cases (RARP), trocar insertion sites were examined on postoperative day 7 with Foley removal for AWH. AWH was defined by a sizable collection of blood below the skin as a result of the surgery. The AccuVein AV400 system was utilized to generate real-time images of venous structures beneath the skin. Comparative… More >

Abstract Introduction: Primary ureteroscopy for nephrolithiasis is often completed without prior ureteral stenting. However, failure can occur due to inability to access the stone, requiring ureteral stenting for passive dilation and a second procedure. This typically results in increased morbidity due to a prolonged period of ureteral stenting and subsequent stent-related symptoms. Patient counseling preoperatively is important to discuss the risk of failure.
Materials and methods: We reviewed all primary ureteroscopies for nephrolithiasis performed by four urologists at our institution from November 2007 to November 2016. Univariate analysis was performed to compare groups with Chi-squared analysis, Fisher’s exact… More >

Abstract Introduction: Minimally invasive nephroureterectomy (MINU) and open nephroureterectomy (ONU) have similar oncological outcomes for treatment of upper tract urothelial carcinoma (UTUC). We investigated perioperative outcomes and predictors of complications associated with MINU and ONU.
Material and methods: Using the National Surgical Quality Improvement Program (NSQIP) database, 912 patients were identified that underwent radical nephroureterectomy for UTUC between 2005 and 2013. Logistic regression and contingency table methods used preoperative covariates to predict rates of major (Clavien-Dindo grade ≥ 3) and 16 common perioperative complications. Additional comparisons between treatment groups were performed using unpaired t-tests, Wilcoxon rank-sum tests, or… More >

Abstract Introduction: Hospital-related costs of renal cancer surgery have been described, but the societal costs of surgery-related lost productivity are poorly understood. We estimated the societal cost of renal cancer surgery by assessing surgery-related time off work (TOW) taken by patients and their caretakers.
Materials and methods: A total of 413 subjects who underwent partial or radical nephrectomy enrolled in an IRB-approved prospective study received an occupational survey assessing employment status, work physicality, income, surgery-related TOW, and caretaker assistance. We excluded subjects with incomplete occupational information or metastatic disease. We estimated potential wages lost using individual income and… More >

Abstract Introduction: To evaluate the effect of urine pH on tumor recurrence rates in patients undergoing surveillance after initial diagnosis of non-muscle invasive bladder cancer (NMIBC).
Materials and methods: All patients diagnosed with NMIBC at a tertiary referral center from January 2004 to March 2015 were reviewed. Our primary outcome was time to first recurrence after transurethral resection of bladder tumor (TURBT). Patients were analyzed according to the average urine pH of all urinalysis data over the surveillance period from TURBT to first recurrence. Kaplan-Meier survival analysis was used to determine differences in median time to recurrence. Cox… More >

Abstract Introduction: Since the advent of prostate-specific antigen (PSA) screening there has been a decreased incidence of lymph node positive disease (LND). Nevertheless, because of possible upgrading, LND is frequently performed with preoperative Gleason 6 prostate cancer. We utilized the Surveillance Epidemiology and End Results (SEER) database to evaluate the frequency of LND and preoperative variables for node positivity in contemporary patients with preoperative Gleason 6 disease.
Materials and methods: SEER-18 registries database was queried for all patients diagnosed with prostate cancer between the years 2010 and 2014. Patients were excluded that had unknown histology or unknown preoperative… More >

Abstract Transitional cell carcinoma is the most common type of bladder cancer in the United States. This case report discusses the finding of primary bladder carcinoid tumor (also called well-differentiated neuroendocrine tumor) in a woman with gross hematuria. With only 15-20 reported cases, primary bladder carcinoid is rare and the approach to treatment is unclear. There have been two muscle-invasive cases reported which required more extensive treatment plans. The patient presented in this case underwent complete transurethral resection of the tumor with the recommendation of surveillance cystoscopy every 3 months. More >

Abstract With the increasing use of minimally invasive technologies for the treatment of benign prostatic enlargement/lower urinary tract symptoms, clinicians must become familiar with the various treatment effects and complications. Here we present a case of treatment defect after transurethral convective radiofrequency-induced water vapor thermal ablation (REZUM) radiographically identified as a prostatic abscess without consideration that the finding may have represented an anticipated treatment defect. This likely led to an unnecessary surgical procedure. This entity should be recognized by urologists and radiologists alike to avoid such interventions in the future. More >

Abstract Introduction: To compare endourology versus pediatric urology exposure to pediatric stone cases during fellowship, comfortability in treating pediatric stone cases, and access to pediatric surgical equipment.
Materials and methods: A survey was distributed to all pediatric urology fellowship programs and the Endourological Society. Age was stratified into < 12 months old, 12 months - 4 years, 5 - 12 years, and 13 - 18 years. Exposure and comfortability performing extracorporeal shock wave lithotripsy (SWL), ureteroscopy (URS), and percutaneous nephrolithotomy (PCNL) were assessed across age groups. Exposure was assessed as “yes/no” and comfortability was scaled from 1-5 (“would… More >
