Occult Renal Cell Carcinoma Manifesting as Nasal Mass and Epistaxis

Sher Singh YadavJanak SinghVishwas BahetiRajeev Mathur

Metastasis of renal cell carcinoma (RCC) to the nasal cavity and paranasal sinuses is rare, with fewer than 50 cases described in the literature. Nasal metastasis as the initial presentation of RCC is even rarer. Metastases to the nasal cavity usually represent advanced disease with poor outcome. The authors report a case of metastatic RCC presenting with right nasal cavity mass and epistaxis, followed by a brief review of the relevant literature.

Ureteral Metastasis as the Presenting Manifestation of Pancreatic Carcinoma

Onkar SinghNand Kishore ArvindShilpi GuptaQutub Ali

We recently cared for a patient with adenocarcinoma of the pancreas who presented with ureteral metastasis followed by hydroureteronephrosis long before the appearance of any symptoms related to the primary lesion. The entity is extremely rare; only seven similar cases are on record in the scientific literature. No recent review exists on this topic. This encouraged us to present our case along with the previous cases of adenocarcinoma of the pancreas with ureteral metastasis that have been reported.

Laparoscopic Nephrectomy for Pyonephrosis During Pregnancy: Case Report and Review of the Literature

Onkar SinghNand Kishore ArvindShilpi Singh GuptaSurbhi SahayKutub AliAnand Dharaskar

The maternal and fetal complications of pyonephrosis during pregnancy can be devastating, thus the call for urgent but safe intervention. Laparoscopic nephrectomy has been used safely and effectively in nonpregnant patients with pyonephrotic kidney. We report on a case of a 28-year-old pregnant woman with pyonephrotic kidney that we believe to be the first such case managed by transperitoneal laparoscopic nephrectomy. A review of the reported cases of laparoscopic nephrectomy for different indications and by different approaches during pregnancy is also presented.

Ureteral Polyp Managed by Endoscopic Techniques

Tal CohenMark MemoJohn GraffShyam Patnaik

Fibroepithelial polyps (FEPs) are rare benign tumors of mesodermal origin. They are found in the ureters 85% of the time, with the remainder located in the renal pelvis and occasionally the bladder. FEPs can present as flank pain, lower abdominal pain, and/or gross hematuria. Previous literature reports management of these benign lesions using open surgical techniques, laparoscopic techniques, and endoscopic management. In this article, the authors present their pure endoscopic management of a large ureteral polyp and a review of the current literature outlining the etiology, clinical presentations, and management techniques for FEP of the ureter.

Breast Cancer Clinical and Translational Research: Analogies and Implications for Prostate Cancer

Androgen-Independent Prostate Cancer

Lea BaerSilvia C Formenti

Breast and prostate cancer, respectively, are the most common cancers in women and in men in the United States. The management of locally advanced prostate cancer involves a multidisciplinary approach, bearing similarity to the therapeutic approach to breast cancer. Better understanding of the molecular biology of these cancers and the identification of the role played by the cancer stem cells and the tumor microenvironment may translate into better clinical decision making regarding risk classification and treatment allocation. A systematic assessment is presented of the many parallel evolutions in defining and treating high-risk breast cancer as they pertain to prostate cancer. [Rev Urol. 2007;9(suppl 2):S28-S39]

Pathologic Guidelines for Orthotopic Urinary Diversion in Women With Bladder Cancer: A Review of the Literature

Therapeutic Challenges

John P SteinVannita Simma-ChangSimon D Wu

Orthotopic lower urinary tract reconstruction to the native intact urethra following radical cystectomy for bladder cancer was slower to gain clinical acceptance for women than for men. Until the 1990s, little was known about the natural history of urethral involvement by urothelial carcinoma in women with primary bladder cancer. The increasing availability of pathologic data to define the incidence of and risks for urethral involvement in women sparked an increasing interest in orthotopic diversion in female patients. Pathologic guidelines have been suggested to identify women suitable for orthotopic diversion. Preoperative involvement of the bladder neck is a significant risk factor for secondary tumor of the urethra, but is not an absolute contraindication, as long as full-thickness, intraoperative frozen-section analysis demonstrates no tumor involvement of the proximal urethra. Although less common, anterior vaginal wall tumor involvement may be a significant risk factor for urethral tumor involvement. Other pathologic parameters, including tumor multifocality, carcinoma in situ of the bladder, and tumor grade and stage, do not seem to be absolute contraindications. Long-term follow-up is critical for all patients. Women undergoing orthotopic reconstruction, if appropriately selected, should be assured of an oncologically sound operation and good function with their neobladder. [Rev Urol. 2006;8(2):54-60]

Clinical Experience With Gene Therapy for the Treatment of Prostate Cancer

New Directions in the Management of Advanced Prostate Cancer

Simon J HallMatthew A Stanizzi

Localized prostate cancer can be treated effectively with radical prostatectomy or radiation therapy. The treatment options for metastatic prostate cancer are limited to hormonal therapy; hormone-refractory cancer is treated with taxane-based chemotherapy, which provides only a modest survival benefit. New treatments are needed. The gene for the initiation of prostate cancer has not been identified; however, gene therapy can involve tumor injection of a gene to kill cells, systemic gene delivery to target and kill metastases, or local gene expression intended to generate a systemic response. This review will provide an overview of the various strategies of cancer gene therapy, focusing on those that have gone to clinical trial, detailing clinical experience in prostate cancer patients.

Nephrolithometric Scoring Systems to Predict Outcomes of Percutaneous Nephrolithotomy

Management Update

Simone L VernezZhamshid OkhunovPiruz MotamediniaVincent BirdZeph OkekeArthur Smith

Currently, there is no single agreement upon an ideal predictive model that characterizes the complexity of renal stones and predicts surgical outcomes following percutaneous nephrolithotomy (PCNL). New predictive tools have recently emerged to systematically and quantitatively assess kidney stone complexity to predict outcomes following PCNL: the Guy’s Stone Score, the CROES nomogram, S.T.O.N.E. nephrolithometry, and S-ReSC score. An ideal scoring system should include variables that both influence surgical planning and are predictive of postoperative outcomes. This review discusses the strengths, weaknesses, and commonalities of each of the above scoring systems. Additionally, we propose future directions for the development and analysis of surgical treatment for stone disease, namely, the importance of assessing radiation exposure and patient quality of life when counseling patients on treatment options.

Nocturia: Evaluation and Current Management Strategies

Management Update

Roger R DmochowskiW Stuart ReynoldsAlan J WeinCasey G KowalikJoshua A CohnSophia DelpeMelissa R KaufmanDoug F Milam

Nocturia is a complex condition that not only significantly affects quality of life, but may be an indicator of systemic disease. Initial assessment includes a detailed history and physical examination and completion of a frequency volume chart to help identify underlying causes, such as sleep disorders, bladder storage disorders, and polyuria. Treatment with alpha-blockers or antimuscarinic medications may help if the underlying cause is determined to be benign prostatic hyperplasia or overactive bladder, respectively. Treatment options for nocturnal polyuria have been limited to behavioral therapy and off-label use of timed diuretics and desmopressin. Desmopressin acetate nasal spray (Noctiva™, Avadel Pharmaceuticals, Chesterfield, MO) was approved by the US Food and Drug Administration in 2017 for the treatment of nocturia due to nocturnal polyuria in adults who awaken at least twice nightly and has shown efficacy in reducing nocturnal voids by $50% in up to 49% of patients in clinical trials.

Leydig Cell Hyperplasia Revealed by Gynecomastia

Case Review

Mohamed Jamal El FassiMoulay Hassan FarihMohamed Fadl TaziSoufiane Mellas

Leydig cell tumors are rare and represent 1% to 3% of all tumors of the testis. Leydig cell tumors affect males at any age, but there are 2 peak periods of incidence: between 5 and 10 years and between 25 and 35 years. Their main clinical presentation is a testicular mass associated with endocrinal manifestations that are variable according to age and appearance of the tumor. Our patient, a 17-year-old adolescent, presented with an isolated and painless hypertrophy of the right mammary gland. Clinical examination found gynecomastia and no testicular mass. Hormonal levels and tumor markers were normal. Testicular sonography showed an ovular and homogeneous right intratesticular mass 6 mm in diameter. We treated the patient with an inguinal right orchidectomy. The anatomopathological study found a nodule of Leydig cell hyperplasia. The patient recovered without recurrence at 8-month follow-up. The patient opted for mammoplasty 2 months after his orchidectomy rather than wait for the spontaneous gradual regression of his gynecomastia, which requires at least 1 year. Leydig cell hyperplasia manifests in the adult by signs of hypogonadism, most frequently gynecomastia. Although many teams prefer total orchidectomy because of the diagnostic difficulty associated with malignant forms, simple subcapsular orchidectomy should become the first-line treatment, provided it be subsequently followed by close surveillance, as it preserves maximum fertility, and these tumors usually resolve favorably.

Venous Thromboembolism in Urologic Surgery: Prophylaxis, Diagnosis, and Treatment

Treatment Update

Kevin R RiceStephen A BrassellDavid G McLeod

Venous thromboembolism (VTE) represents one of the most common and potentially devastating complications of urologic surgery. With VTE’s rapid onset of symptoms, association with a precipitous clinical course, and high mortality rate, all urologists should be well versed in appropriate prophylaxis, prompt diagnosis, and expeditious treatment. A MEDLINE® search was performed for articles that examined the incidence, diagnosis, and treatment of VTE in urologic surgery. Additional articles were reviewed based on cited references. There is a paucity of prospective studies on VTE in the urologic literature with most recommendations for urologic surgery patients being extrapolated from other surgical disciplines. Retrospective studies place VTE incidence rates in major urologic surgeries among the highest reported—highlighting the importance of thromboprophylaxis. Conversely, VTE was rarely reported in association with endoscopic and laparoscopic procedures making mechanical thromboprophylaxis sufficient. Recent literature reveals delayed VTE occurring after hospital discharge to be a persistent threat despite inpatient preoperative prophylaxis. Computed tomographic angiography has emerged as the test of choice for diagnosing pulmonary embolism, whereas lower extremity duplex sonography is recommended for diagnosing deep venous thrombosis. Traditional angiography is rarely used. Treatment of VTE involves therapeutic anticoagulation for various lengths of time based on presence and reversibility of patient risk factors as well as number of events. Perioperative thromboprophylaxis should be considered in all major urologic surgeries. Urologists should be familiar with incidence rates, recommended prophylaxis, appropriate diagnosis, and treatment recommendations for VTE to minimize morbidity and mortality. The limited number of prospective, randomized, controlled trials evaluating the use of thromboprophylaxis in urologic surgery demonstrates the need for further research.

Implementation of a Centralized, Cost-effective Call Center in a Large Urology Community Practice

Original Research

Gary M KirshStephen F KappaChris McClainKrista WallacePaul CinquinaDon LawsonMary M SmithEarl WalzBrooke Edwards

Call centers provide front-line care and service to patients. This study compared call-answering efficiency and costs between the implementation of an internal, centralized call center (January to July 2019) and previously outsourced call-center services (January to July 2018) for a large urology community practice. Retrospective review of call metrics and cost data was performed. Internal call-center leadership, training, and culture was examined through survey of staff and management. A total of 299,028 calls with an average of 5751 calls per week were answered during the study periods. The Average Speed of Answer (ASA) was 1:42 (min:s) for the outsourced call center and 0:14 for the internal call center (P < 0.001), with 70% of outsourced calls answered under 2 minutes compared with 99% of calls for the internal call center (P < 0.001). The Average Handle Time (AHT) for each outsourced call was 5:32 versus 3:41 for the internal call center (P < 0.001). The total operating expenses were 7.7% lower for the internal call center. Surveys revealed the importance of engaged leadership and staff training with feedback, simplified work algorithms, and expanded clinical roles. We found that internal, centralized call centers may provide a call-answering solution with greater efficiency and lower total operating expense versus an outsourced call center for large surgical practices. A culture that emphasizes continuous improvement and empowers call-center staff with expanded clinical roles may ultimately enhance patient communication and service.
