A narrative clinical trials review in the realm of focal therapy for localized prostate cancer.

Background And Objective: The role of focal therapy in the treatment of localized prostate cancer is evolving. However, despite accumulating evidence, current guidelines and regulatory bodies refrain from endorsing focal therapy outside of clinical trials. Our goal was the to review the focal therapy realm for ongoing clinical trials and high impact recently published trials.

Trends in the use of immediate postoperative intravesical chemotherapy following transurethral resection of bladder tumors.

Purpose: The use of immediate postoperative intravesical chemotherapy (IVC) following transurethral resection of bladder tumor (TURBT) has been shown to reduce the rate of recurrence of nonmuscle invasive bladder cancer. Historically, utilization of IVC following TURBT has been low. We sought to determine the rate of immediate postoperative IVC following TURBT, as well as assess factors that may influence its use.

Prostate cancer and solid organ transplantation: patient management and outcomes.

Objective: To analyse the management and outcomes of individuals diagnosed with prostate cancer either before or after organ transplantation, as the impact of organ transplantation and associated immunosuppression on the incidence, progression, and mortality of prostate cancer remains an area of substantial clinical interest and uncertainty.

Patients And Methods: We conducted a retrospective analysis of patients from two tertiary care centres who had solid organ transplantation and were diagnosed with prostate cancer before or after organ transplantation. Data collected included demographics and clinical information.

The impact of metabolic syndrome on short term radical cystectomy complications.

Purpose: Radical cystectomy is a highly morbid procedure with short term perioperative complications rates cited to be as high as 60%. Short term perioperative complications have been demonstrated to be more frequent in underweight and overweight patients. We sought to evaluate the impact of metabolic syndrome on surgical outcomes.

Necrotizing granulomatous epididymo-orchitis post intravesical BCG administration after brachytherapy for prostate cancer.

Urothelial carcinoma of the bladder remains a challenging disease to treat. Intravesical instillation of BCG has demonstrated tremendous efficacy in preventing recurrence. BCG related necrotizing granulomatous epididymo-orchitis is rare and has not been previously linked to brachytherapy for adenocarcinoma of the prostate.

Robotic or open superficial inguinal lymph node dissection as staging procedures for clinically node negative high risk penile cancer.

Objective: To evaluate perioperative and oncologic outcomes of a cohort of clinically node negative high-risk penile cancer patients undergoing robotic assisted inguinal lymph node dissection (RAIL) compared to patients undergoing open superficial inguinal lymph node dissection (OSILND).

Patients And Methods: We retrospectively reviewed the clinical characteristics and outcomes of clinically node negative high-risk penile cancer patients undergoing RAIL at MDACC from 2013-2019. We sought to compare this to a contemporary open cohort of clinically node negative patients treated from 1999 to 2019 at MDACC and Moffit Cancer Center (MCC) with an OSILND.

Bloodless surgery in urologic oncology: A review of hematologic, anesthetic, and surgical considerations.

The urologic oncology patient who refuses blood transfusion can present unique challenges in perioperative blood management. Since blood loss and associated transfusion can be expected in many complex urologic oncology surgeries, a multidisciplinary approach may be required for optimal outcomes. Through collaboration with the hematologist, anesthesiologist, and urologist, various techniques can be employed in the perioperative phases to minimize blood loss and the need for transfusion.

Risk factors and survival outcomes for upstaging after inguinal lymph node dissection for cN1 penile squamous cell carcinoma.

Objectives: To identify incidence and risk factors for upstaging from cN1 to pN2/N3 at inguinal lymphadenectomy (ILND) for penile cancer (pSCC). Our secondary objective is to assess survival outcomes and associations for cN1 patients undergoing ILND.

Subjects/patients And Methods: Patients with pT≥1cN1cM0 pSCC who underwent bilateral ILND and had complete data were identified in a multi-institutional international cohort from 8 referral centers in 7 countries diagnosed from 1980 to 2017.

Patterns of Recurrence following Inguinal Lymph Node Dissection for Penile Cancer: Optimizing Surveillance Strategies.

Purpose: Our primary objective is to detail the incidence, site, and timing of penile squamous cell carcinoma (pSCC) recurrence after inguinal lymph node dissection (ILND).

Materials And Methods: We performed a retrospective analysis of 551 patients who underwent ILND for pSCC from 2000 to 2017. The primary outcome was pSCC recurrence after ILND.

Renal schwannoma: A case report and literature review of a rare and benign entity mimicking an invasive renal neoplasm.

Schwannomas of the kidney are rare with only a handful of cases reported in literature. We present a case of a large Schwannoma of the right kidney causing mass effect with imaging characteristics thought to represent renal cell carcinoma. On imaging, these masses present similarly to solid renal masses and are therefore indistinguishable without tissue diagnosis.

Reliability of Serum Tumor Marker Measurement to Diagnose Recurrence in Patients with Clinical Stage I Nonseminomatous Germ Cell Tumors Undergoing Active Surveillance: A Systematic Review.

Purpose: Men with nonseminomatous germ cell tumors of the testicle without evidence of residual disease after radical orchiectomy (clinical stage I) are increasingly managed with active surveillance. The guideline-recommended cornerstones of surveillance are conventional serum tumor markers and computerized tomography. The reliability of serum tumor markers as a tool to diagnose early recurrence of clinical stage I nonseminomatous germ cell tumors is unclear.

Prostatic artery embolization for bladder outlet obstruction in the setting of prior posterior urethroplasty.

This case presents a patient with a remote history of complex posterior urethral repair related to a prior motorcycle accident who presented to the urology clinic in urinary retention with associated lower urinary tract symptoms. Due to his altered anatomy, traditional outlet procedures were deferred due to significant reported risks of post treatment urinary incontinence. Decision was made to proceed with prostatic artery embolization, and at follow up he reported resolution of his urinary retention and significant symptomatic improvement in his voiding without development of urinary incontinence.

Acupuncture for Analgesia During Transurethral Resection of Bladder Tumor.

Acupuncture has been widely studied, and theories regarding its analgesic mechanism of action have been proposed. It has been used for procedural analgesia; however, no reports of its use in urologic surgery have been reported. In this case report, we demonstrate how acupuncture can be used as an alternative to general anesthesia for transurethral resection of bladder tumor (TURBT).

Rare urologic tumors.

Purpose Of Review: Management of genitourinary malignancy is likely to encompass a large portion of most of the urologist's practice. The challenge for the modern urologist is not only in understanding the management of commonly seen genitourinary malignancies, but also in recognizing unusual variants and their differences in management. This is evermore important as new technologies have refined the ability to identify rare entities.

Sterols of the green-pigmented, freshwater raphidophyte, Gonyostomum semen, from Scandinavian lakes.

Sterols are a class of membrane-reinforcing, ringed lipids which have a long history of examination in algae as a means of deriving chemotaxonomic relationships and as potential lipidic biomarkers. The Raphidophyceae represent a class of harmful, bloom-forming, marine and freshwater algae. To date, there have been four published examinations of their sterol composition, focusing primarily on brown-pigmented, marine species within the genera, Chattonella, Fibrocapsa, and Heterosigma.
