Abstract Introduction: To characterize the relationship between tumor location and choice in selecting surgical cryoablation (SCA) versus percutaneous cryoablation (PCA) for treatment of renal masses.
Materials and methods: MEDLINE search was performed to identify studies in which cryoablation was used as therapy for renal masses. Tumor location was stratified as anterior, posterior, or lateral. Lesions were also described by endophycity (endo-, meso-, or exophytic) and polarity (upper, mid, or lower pole). Treating specialty was stratified as urology, radiology, or both. Comorbidity reporting rates were indexed for each manuscript.
Results: Thirty-seven manuscripts included 2344 lesions treated by SCA or PCA… More >

Abstract Introduction: Obese patients are at increased risk for renal stones as well as treatment failures due to increased skin-to-stone distances (SSD) and harder stone compositions. We investigated the relationships between obesometric parameters (body mass index [BMI], body fat distribution, and obesity-related hormone levels) with SSD and stone hardness.
Materials and methods: We prospectively enrolled patients undergoing stone interventions at our institution. Computed tomography (CT) scans were analyzed; adipose tissue was identified according to Hounsfield units (HU) and separated into subcutaneous (SAT) and visceral (VAT) components. The pixels were averaged at three levels to calculate fat distribution: %VAT… More >

Abstract Introduction: Perioperative blood transfusion (PBT) has been shown to contribute to cancer progression and mortality. This study sought to determine the impact of PBT during radical cystectomy on cancer-specific survival (CSS) and overall survival (OS).
Materials and methods: The Columbia University Urologic Oncology Database was reviewed for patients who underwent a radical cystectomy (RC) from 1989 to 2010 (n = 638). PBT was defined as non-autologous packed red blood cells (PRBC) received during the same hospital stay as the radical cystectomy. Clinical and pathological variables were compared between the cohorts, and survival analysis was performed using the… More >

Abstract Introduction: The aim of this study was to compare the efficacy of GreenLight 120-HPS (American Medical Systems, Minnetonka, Minnesota, USA) laser vaporization for men with obstructive benign prostatic hyperplasia (BPH) according to prostate volumes: <60 cc, 60–100 cc, and >100 cc.
Material and methods: The clinical data of 250 men with symptomatic BPH who underwent photoselective vaporization prostatectomy (PVP) by a single surgeon between July 2007 and August 2009 were retrospectively analyzed. Prostate volumes were measured by transrectal ultrasonography (TRUS). Functional evaluations were performed at 3, 6, and 12 months, with prostate-specific antigen (PSA) levels obtained at… More >

Abstract Introduction: To assess the quality of transurethral resection of bladder tumors (TURBTs) performed by "senior" and "junior" urologists for pT1 tumors in terms of detrusor muscle (DM) presence and recurrence rate at 3-month first cystoscopy (RR-FC). Non-muscle invasive bladder cancer (NMIBC) is a heterogeneous group with differing biological potentials. Tumors invading lamina propria (pT1) have an increased propensity for recurrence and progression. Accurate staging at the time of primary TURBT, including the presence of DM, is crucial to avoid understaging and unnecessary delay in definitive treatment.
Materials and methods: We analyzed our maintained bladder tumor database (TURBTs… More >

Abstract Introduction: Laparoscopic (LPN) and robotic partial nephrectomy (RPN) may offer similar advantages for nephron-sparing surgery (NSS). We evaluated the perioperative outcomes and complications of LPN versus RPN and sought to evaluate if one technique may have more favorable outcomes over another based on tumor characteristics.
Materials and methods: All patients who underwent LPN and RPN by a single surgeon were retrospectively reviewed. The surgeon almost exclusively performed LPN from February 2009 to January 2011 and RPN from January 2011 to January 2012. Patient demographics, tumor characteristics, perioperative outcomes, short-term renal functional data, and complications were reviewed. Operative… More >

Abstract Testicular cancer is the most common solid malignancy of men aged 15-40 years and metastasizes in a predictable manner via lymphatic spread. Involvement of metastatic testicular cancer to the prostate is an exceedingly rare event which has only been previously described in patients with seminomatous germ cell tumors. In this report, we present a case of a 42-year-old man who presented with metastatic testicular cancer to the prostate 8 years after his original diagnosis of a mixed germ cell left testicular tumor.

Abstract Theoptimalmethodofvesico-vaginalfstula(VVF)repair remains undetermined. Almost all previous descriptions of laparoscopic/robotic fstula repair involve utilizing a vertical cystotomy to identify the fsula. Avoidance of an intravesical approach to vesico-vaginal fstula repair may decrease patient morbidity. Patient selection, patient positioning, fstula recognition, port placement, intra-operative dissection techniques, flap formation, and repair are outlined in this video of robotic repair of vesico-vaginal fstula utilizing an extravesical approach. The extravesical robotic repair has been successfully utilized in two patients with VVF following hysterectomy. This manuscript and video demonstrates that vesico-vaginal fstulae can be repaired with a robotic assisted extravesical approach More >

Abstract Prostatic utricle (PU) stones are rare and the surgical treatment of such PU anomalies has proved challenging given their location adjacent to the posterior urethra and proximity to important fertility and continence structures. We report the case of a 58-year-old male with hypospadias, microphallus, and irritative lower urinary tract symptoms (LUTS) found to have a large PU stone. He underwent successful complete endoscopic removal of the stone via transurethral unroofing and holmium laser litholapaxy. We conclude that it is an effective alternative to other surgical techniques once size of the stone and the patient’s individual More >

Abstract Sacral neuromodulation (SNM) has become a standard treatment option for patients suffering from urinary urge incontinence, urgency-frequency, and/or nonobstructive urinary retention refractory to conservative and pharmacologic treatment. Since its initial development, the manufacturer of InterStim therapy (Medtronic, Inc., Minneapolis, MN, USA), has introduced technical modifications, while surgeons and researchers have adapted and published various innovations and alterations of the implantation technique. In this article, we feature our SNM technique including patient selection, comprehensive dialogue/evaluation, procedure details, and appropriate follow up. Although there is often great variability in patients with lower urinary tract dysfunction, we maintain More >

Abstract Partial nephrectomy (PN) has gained popularity over the past two decades as an alternative to radical nephrectomy (RN) in patients with small renal masses. Morbidity and mortality from PN have been shown to be lower than from RN, while oncologic outcomes have been shown to be equivalent for tumors < 7 cm. PN has become increasingly popular in academic centers, but the general urologic community continues to lag behind. The reason for this is not known, but may be related to the relatively high complication rate, including delayed complications associated with inadequate closure. Here we More >
