To quantify how surgeons translate two-dimensional (2D) CT or MRI data to a three-dimensional (3D) model and evaluate if 3D printed models improve tumor localization.

To describe utilization patterns of ureteral stent placement during ESWL.

Nocturnal polyuria (NP), the most common etiology of nocturia, can be caused by various medical conditions, including cardiovascular disease, obstructive sleep apnea, renal tubular dysfunction, as well as medications (e.g. diuretics) and/or behavioral patterns. NP in the absence of underlying medical conditions has been described as nocturnal polyuria syndrome (NPS) and is thought be the result of impaired circadian release of endogenous arginine vasopressin (AVP). Desmopressin, a synthetic AVP analog, has been shown to be an effective replacement therapy in adults with nocturia due to NP.

Acute pancreatitis a common diagnosis. Although extremely rare, extravasated pancreatic fluid has the potential to third-space into the peritoneal cavity or retroperitoneal space. We report the case of a 33-year old male with idiopathic subacute pancreatitis who developed acute scrotal pain and swelling. Computer tomography (CT) of the abdomen/pelvis revealed tracking of peritoneal fluid into the scrotum consistent with a pancreatic hydrocele, confirmed by ultrasound. He was taken to the operating room for exploration and evacuation of the scrotal hydrocele.

An otherwise healthy 25-year-old woman diagnosed with a renal neoplasm on work-up of new onset hypertension was referred to Urology clinic for further evaluation and management. The patient initially presented to her primary care provider three weeks prior for a well visit and was diagnosed with stage 2 hypertension with a blood pressure of 172/117 mmHg and heart rate of 87 beats per minute. She endorsed history of intermittent headaches, but denied palpitations, diaphoresis, anxiety, or visual changes.

Nocturnal polyuria (NP), the most common etiology of nocturia, is a bothersome condition characterized by overproduction of urine at night.1,2 NP may result from abnormalities in the normal circadian variation in endogenous arginine vasopressin (AVP) secretion,3 and it can also be associated with various medical conditions, including congestive heart failure, diabetes mellitus, obstructive sleep apnea, peripheral edema, excessive night-time fluid intake, as well as “normal” aging.4 There is a strong need to manage this burdensome condition by identifying the causative factors and associated comorbidities.

Superior Mesenteric Artery Syndrome (SMAS) is a rare condition of external duodenal compression in the angle between the superior mesenteric artery and aorta. We report a case of SMAS following augmentation cystoplasty in a young patient.

Sepsis following transrectal prostate biopsy occurs in 2-5% of cases and the risk is increasing. We performed a comprehensive literature search for the cost of post-prostate biopsy sepsis to define the potential cost savings of reducing infectious complications. Reporting of cost is varied and presents a challenge to interpretation. Length of hospitalization ranged from 1.1-14 days and the percent admitted to an ICU ranged from 1.1-25%. The estimated cost of sepsis post-prostate biopsy, adjusted for inflation, ranged from $8,672-$19,100.

To assess surgical outcomes of penile prosthesis implantation in transgender men who underwent phalloplasty.

To evaluate the presenting complications of patients to reconstructive urologists after masculinizing gender affirming genital reconstructive surgery (GRS) performed elsewhere.

A 70 year old female was referred to the outpatient department of our institute with complaints of fatigue, bilateral flank pain and loss of appetite for the past 1 month. She also complained of shortness of breath and decreased urine output for the past 7 days. Previous surgical and medical history of the patient was unremarkable. She was thin built and undernourished with a BMI of 17kg/m2. On examination, the patient had bilateral pedal edema and fine crackles on respiratory examination. The cardiovascular examination of the patient was essentially normal.

To investigate trends in stress urinary incontinence (SUI) surgery before and after the 2011 FDA notification and the 2014 AUGS/SUFU position statement.

To evaluate the impact of resident involvement in robot assisted laparascopic prostatectomy (RALP) on oncologic, functional, and intraoperative outcomes, both short and long term.

A 69-year-old man with a history of rheumatoid arthritis and pulmonary fibrosis presented with an incidentally discovered 11.5 cm left renal mass with a level 3 inferior vena cava (IVC) tumor thrombus, including involvement of the left adrenal and lumbar veins. The thrombus was highly vascularized as shown in Figure 1A-C. Preoperative evaluation was negative for metastatic disease and the serum creatinine (SCr) level was 1.55 mg/dL, correlating with an estimated glomerular filtration rate (eGFR) of 46 mL/min/1.73m2.

We reviewed the literature for the biologic, prognostic, and predictive significance of circulating prostate cancer tumor cells (CTCs), and circulating tumor DNA (ctDNA) in the blood of metastatic castration resistant prostate cancer patients (mCRPC). CTCs demonstrate robust prognostic value independent of PSA in predicting overall survival. The CTC androgen receptor variant receptor 7 (AR-V7) phenotype predicts resistance to androgen receptor synthesis inhibitors and sensitivity to taxane based chemotherapy in mCRPC patients who are candidates for second line therapy.

To report outcomes, complications, and risk factors of a population cohort undergoing Male-to-Female (MtF) gender affirmation surgery via penile-inversion vaginoplasty by a single surgeon at a large academic institution. As gender dysphoria awareness increases among the medical community, so does the population of patients seeking gender-affirmation surgery.

To determine if combined administration of LIMK2 and JNK inhibitors in a rat model of ED induced by cavernosal nerve (CN) injury could restore erectile function by suppressing both cavernosal apoptosis and fibrosis via rectification of molecular pathways related to the structural alterations.

To investigate the influence of type of anticoagulation - direct oral anticoagulants (DOAC) vs. vitamin K antagonists (VKA) – on length of hospital stay (LOS) and hospitalisation rates in patients with visible haematuria, as visible haematuria in anticoagulated patients can be distressing, difficult to control and even life-threatening.

To address the incidence and potential risk factors of port site metastasis (PSM) in patients who underwent laparoscopic radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC).

To evaluate programmed death ligand 1 (PD-L1) staining fidelity between the primary tumor and associated lymph node metastases in bladder cancer. To secondarily evaluate whether neoadjuvant chemotherapy (NAC) affects this relationship.
