Abstract Introduction: To compare renal function changes after radical nephroureterectomy (RNU) in patients with upper tract urothelial carcinoma (UTUC) based on the presence of preoperative hydronephrosis.
Materials and methods: Clinicopathologic data of 208 patients with UTUC treated surgically from 1998 to 2013 were compiled. Patients with bilateral disease, less than 1 month follow up, missing hydronephrosis data, or who underwent nephron-sparing approaches were excluded. Estimated glomerular filtration rate (eGFR) was calculated preoperatively, at first follow up (within 3 months) and at last follow up using the Modification of Diet in Renal Disease equation. Events were defined as new-onset… More >

Abstract Introduction: Infectious complications are common after radical cystectomy (RC), and allogeneic blood transfusions may increase infection risk by an immunosuppressive effect. While it has been suggested that perioperative blood transfusion (PBT) may be associated with adverse oncologic outcomes after RC, no large analyses have assessed whether PBT increases the risk of perioperative infection after RC.
Materials and methods: We used the Nationwide Inpatient Sample (1998 to 2011) to study the rate of PBT during RC for bladder cancer and identify infectious complications. We compared rates of infectious complications in patients who did and did not receive PBT… More >

Abstract Introduction: To assess 30-day morbidity and mortality following partial nephrectomy (PN) and radical nephrectomy (RN) with relation to the administration of perioperative blood transfusions (PBT).
Materials and methods: The National Surgical Quality Improvement Program was queried for patients with malignant renal tumors (International Classification of Diseases Ninth Revision codes 189-189.2) who underwent RN (Current Procedure Terminology codes 50220, 50225, 50230, 50234, 50236, 50545, 50546, 50548) or PN (50240, 50543) between 2005-2013. Patients were stratified by transfusion status and assessed for postoperative outcomes both separately and in composite, including morbidity, mortality, infectious complications, and pulmonary complications. Univariate and… More >

Abstract Introduction: Holmium laser ablation of the prostate (HoLAP) is a surgical approach for treatment of benign prostatic hyperplasia (BPH). Limited evidence suggests laser ablation/vaporization is inferior to enucleation with respect to reoperation rates. Our objective was to determine if properly performed laser ablation results in outcomes similar to enucleation.
Materials and methods: A total of 198 patients with moderate to severe lower urinary tract symptoms and/or acute urinary retention had holmium laser enucleation of the prostate (HoLEP) or HoLAP between 2008 and 2014. Patients with metastatic prostate cancer, prior pelvic radiation, or bladder cancer involving the bladder… More >

Abstract Introduction: The European Association of Urology (EAU) and the American Urological Association (AUA) guidelines recommend percutaneous nephrolithotomy (PCNL) as the first-line treatment of renal stones greater than 20 mm, however multistage retrograde intrarenal stone surgery (RIRS) is reported to have high stone-free rates (SFR), fewer complications and a rapid learning curve. This study presents our experience of RIRS in the management of 2 cm-4 cm renal stones.
Materials and methods: A retrospective study was performed of all patients who underwent RIRS for 2 cm-4 cm renal stones over a period of 22 months. The demographics of 71… More >

Abstract Introduction: To determine the contemporary practice patterns of academic emergency department (ED) providers in the United States for an episode of acute renal colic.
Materials and methods: A 30-question survey was developed to assess ED providers' clinical decision making for an index patient with acute renal colic. The survey population was all attending and resident physicians affiliated with an American emergency medicine residency program with an institutional profile available on the Society for Academic Emergency Medicine (156 programs; 95% of programs in the United States). The survey was conducted in October 2014. A response rate of 8.1%… More >

Abstract We describe the case of a 50-year-old male with achondroplastic dwarfism who presents with a renal mass in his left kidney concerning for renal cell carcinoma. The patient successfully underwent a robotic partial nephrectomy, which revealed a T1a renal cell carcinoma. The tumor was excised successfully without any intraoperative complications demonstrating that a robotic partial nephrectomy is technically both safe and effective in patients with achondroplastic dwarfism.

Abstract Urothelial carcinoma is the 2^nd most common cancer of the urinary tract and accounts for the majority of cases of bladder cancer. Metastases are not infrequently encountered, increasing with disease stage and are most commonly seen in the bones and lungs. Many other sites have been described including the omentum, liver, and ovaries. An extremely rare site of metastatic disease however is within the vagina. Here we present a case of a probable vaginal “drop metastasis” from previously treated urothelial carcinoma in the ureter and bladder. More >

Abstract Extramammary Paget’s disease (EMPD) is a rare intraepithelial adenocarcinoma arising from apocrine glands. We describe an innovative surgical technique to manage extensive cutaneous malignancies in a notoriously challenging location. The patient is a 78-year-old male who presented with “jock itch” on his left groin refractory to topical treatment. A shave biopsy of the lesion demonstrated non-invasive EMPD which yielded a urology consult. Rather than the standard wide local excision (WLE), which can lead to positive margins, progression, and recurrence, we used a modified the Mohs technique and staged the procedure, providing excellent oncologic and cosmetic More >

Abstract Subcapsular hematoma is an uncommon complication after ureteroscopy and laser lithotripsy. We report on a 38-year-old male with an 8 mm lower pole stone who underwent a left ureteroscopy and laser lithotripsy. The stone was successfully fragmented. Several hours after being discharged home, the patient returned complaining of back pain and hematuria. He was hemodynamically stable. Laboratory exams were normal. ACT study showed a crescent renal subcapsular hematoma surrounding the left kidney. The patient was admitted to the ward for conservative treatment. No additional intervention was necessary. Most subcapsular hematomas tend to resolve spontaneously. More >

Abstract Abiraterone acetate (AA) is a selective irreversible inhibitor of CYP 17, a key enzyme in androgen biosynthesis. The efficacy and safety of AA in improving survival and quality of life in metastatic castration resistant prostate cancer (mCRPC) has been demonstrated in two landmark clinical trials (COU-AA-301 and COU-AA-302). This article will review the rationale, pharmacology, clinical indications and contraindications, administration, and adverse effects of AA administration in mCRPC. More >
