Background And Objectives: Operating room costs contribute significantly to the overall expenditure for inpatient care. We evaluated a simple way to reduce urology operating room costs by limiting the loss from unused disposable items.
Methods: Baseline data were collected on opened and unused disposable items.
Introduction: Reduction of opioids is an important goal in the care of patients undergoing radical cystectomy (RC). Liposomal bupivacaine (LB) has been shown to be a safe and effective pain reliever in the immediate postoperative period and has been reported to reduce postoperative opioid requirements. Since the liposomal formulation is predicated on slow systemic absorption, the amount of bupivacaine administered is notably higher than that typically used with standard bupivacaine (SB) formulations.

Gross hematuria after this procedure has been reported to be mild and transient. This report highlights a case of refractory transfusion-dependent hematuria after the PUL procedure in addition to its management with selective prostatic arterial embolization (PAE).

Methods: We conducted an observational study examining the prostatic urethra anatomy.
We present a case of cytomegalovirus (CMV) native kidney nephritis and prostatitis in a CMV D+/R- kidney transplant recipient who had completed six months of CMV prophylaxis four weeks prior to the diagnosis of genitourinary CMV disease. The patient had a history of benign prostatic hypertrophy and urinary retention that required self-catheterization to relieve high post-voiding residual volumes. At 7 months post-transplant, he was found to have a urinary tract infection, moderate hydronephrosis of the transplanted kidney, and severe hydroureteronephrosis of the native left kidney and ureter, and underwent native left nephrectomy and transurethral resection of the prostate.

The Enhanced Recovery After Surgery (ERAS) protocol has been applied to RC showing decreased hospital stay without increased morbidity. To evaluate the specific causes of hospital readmissions in RC patients treated before and after adoption of an ERAS protocol at our institution.

Classification is generally based on the organ of origin in the urinary tract and the termination of the fistula in the segment of the gastrointestinal tract. Surgery is often necessary.

Materials And Methods: We identified all urethral catheter consults obtained by urology residents at three tertiary care hospitals from October 2009 through October 2010. Only consults for inability to place urethral catheter by the referring team were included; hematuria or clot retention were excluded.
Introduction: There is currently a great deal of interest in the possible use of focal therapies for prostate cancer, since such treatments offer the prospect for control or cure of the primary disease with minimal side effects. Many forms of thermal therapy have been proposed for focal ablation of prostate cancer, including laser, high intensity ultrasound and cryotherapy. This review will demonstrate the important roles that magnetic resonance imaging (MRI) guidance can offer to such focal ablation, focusing on the use of high intensity ultrasonic applicators as an example of one promising technique.
View Article and Find Full Text PDFObjectives: The aims of this study were to evaluate in a canine model applicators designed for ablation of human benign prostatic hyperplasia (BPH) in vivo under magnetic resonance imaging (MRI) guidance, including magnetic resonance thermal imaging (MRTI), determine the ability of MRI techniques to visualize ablative changes in prostate, and evaluate the acute and longer term histologic appearances of prostate tissue ablated during these studies.
Materials And Methods: An MRI-compatible transurethral device incorporating a tubular transducer array with dual 120° sectors was used to ablate canine prostate tissue in vivo, in zones similar to regions of human BPH (enlarged transition zones). Magnetic resonance thermal imaging was used for monitoring of ablation in a 3-T environment, and postablation MRIs were performed to determine the visibility of ablated regions.
Aim: To review current data available on use of prostate specific antigen for screening healthy men for prostate cancer.
Methods: Literature was reviewed and the guidelines from, American cancer Society, American Urologic Association was reviewed.
Results: Current screening protocols lead to over diagnosis of prostate cancer.

A patient with benign prostatic hyperplasia presented with chronic lower urinary tract symptoms despite prior surgery and continued medical therapy. Using a magnetic resonance imaging-guided transperineal approach, two cryoprobes were placed into the transition zone of the prostate gland, and two cryoablation freeze-thaw cycles were performed. At 10 weeks after treatment, the frequency of nocturia had decreased from once every 1.
View Article and Find Full Text PDFObjectives: • To investigate the Prostatic Urethral Lift (PUL) procedure, a novel, minimally invasive treatment for symptomatic benign prostatic hyperplasia (BPH), which aims to mechanically open the prostatic urethra without ablation or resection. • To demonstrate the safety and feasibility of this procedure and to make an initial assessment of effectiveness.
Patients And Methods: • The PULprocedure was performed on 19 men in Australia.
Background: Tyrosine kinase inhibitors (TKI) have dramatically changed the management paradigm of advanced renal cell carcinoma (RCC) and are increasingly being used preoperatively to achieve cytoreduction.
Objective: To review our case series of post-TKI surgical procedures to add to the current perioperative efficacy and complication profile.
Materials And Methods: Between October 2006 and February 2010, 14 cytoreductive nephrectomies, radical nephrectomies, and metastectomies were performed after neoadjuvant sunitinib or sorafenib for advanced RCC.

Major clinical issues in bladder cancer include the identification of prediction markers and novel therapeutic targets for invasive bladder cancer. In the current study, we describe the isolation and characterization of a tumor-initiating cell (T-IC) subpopulation in primary human bladder cancer, based on the expression of markers similar to that of normal bladder basal cells (Lineage-CD44(+)CK5(+)CK20(-)). The bladder T-IC subpopulation was defined functionally by its enriched ability to induce xenograft tumors in vivo that recapitulated the heterogeneity of the original tumor.

Background: A 76-year-old man who underwent cystoprostatectomy with ileal conduit urinary diversion for muscle-invasive bladder cancer presented to his urologist 4 years later with episodes of spontaneous gross hematuria filling his ostomy bag with fresh clots.
Investigations: Physical examination, urine culture, urine cytology, peripheral smear, complete blood count, loopogram, CT-intravenous pyelogram, loop endoscopy, bilateral ureteroscopy, liver function tests, CT angiography, (99m)Tc-tagged red cell scan, hepatitis panel, measurement of transjugular wedge pressure, transjugular liver biopsy with pathologic analysis and re-evaluation of CT angiogram.
Diagnosis: Hematuria secondary to portal hypertension.
Purpose: Identification of patients most likely to benefit from salvage radiotherapy (RT) using postoperative (postop) prostate-specific antigen (PSA) kinetics.
Methods And Materials: From 1984 to 2004, 81 patients who fit the following criteria formed the study population: undetectable PSA after radical prostatectomy (RP); pathologically negative nodes; biochemical relapse defined as a persistently detectable PSA; salvage RT; and two or more postop PSAs available before salvage RT. Salvage RT included the whole pelvic nodes in 55 patients and 4 months of total androgen suppression in 56 patients.
