Abstract Introduction: The Clavien-Dindo (CD) and Comprehensive Complication Index (CCI) are two grading systems that annotate adverse events following surgical procedures. We compare these two classification systems in a cohort of patients undergoing radical nephroureterectomy (RNU).
Materials and methods: The charts of 110 consecutive RNU patients were reviewed for complications occurring within 30 days of surgery. Grading by the CD classification system and values for CCI were calculated. Bivariate and multivariate analysis identified associations between perioperative variables and complications, as well as relationship to hospital length of stay.
Results: Sixty-seven men and 43 women with a median age of… More >

Abstract Introduction: During their lives, 1 in 8 men will be diagnosed with prostate cancer. Several drugs have been shown to decrease prostate cancer risk, but have not been widely used in prostate cancer prevention because of concerns about side-effects and cost-effectiveness. Statins are indicated for prevention of cardiovascular disease, have an excellent benefit to risk profile, and some studies suggest that statins may reduce the risk of prostate cancer.
Materials and methods: We performed a systematic search of Medline (Ovid), EMBASE (Ovid), and PubMed. This search informed a narrative review of the biological rationale for why statins… More >

Abstract Introduction: Early biochemical recurrence after prostate cancer surgery is associated with higher risk of aggressive disease and cancer specific death. Many new tests are being developed that will predict the presence of indicators of aggressive disease like early biochemical recurrence. Since recurrence occurs in less than 10% of patients treated for prostate cancer, validation of such tests will require expensive testing on large patient groups. Moreover, clinical application of the validated test requires that each new patient be tested. In this report we introduce a two-stage classifier system that minimizes the number of patients that must… More >

Abstract Introduction: To evaluate safety and excellent cosmetic outcome with laparoendoscopic single-site surgery (LESS). In this study, we compared the usefulness and efficacy of LESS versus conventional laparoscopic surgery for the treatment of urachal remnants.
Materials and methods: We retrospectively reviewed the medical records of 20 consecutive patients who underwent either conventional laparoscopic surgery or LESS from January 2007 to February 2015 at Kansai Medical University Hospital. Ten patients underwent surgery using the standard laparoscopic 3-port technique, and 10 patients underwent LESS. The patients included 12 males and 8 females (mean age, 24.5 years; range, 10-68 years). The… More >

Abstract Introduction: Multiple sclerosis (MS) is the commonest progressive neurological disease affecting young people. With advancing disease, management of neurogenic detrusor overactivity (NDO) based on antimuscarinics may prove inadequate and if based on botulinum toxin, may necessitate clean intermittent self-catheterization. The aim of the study was to evaluate the effectiveness of combined mirabegron and desmopressin administration in the treatment of NDO in patients with MS.
Materials and methods: Sixty patients diagnosed with MS and NDO were evaluated. All had received treatment with solifenacin 10 mg/daily for 3 months and were displeased with the results. Patients were divided in… More >

Abstract Introduction: To assess the outcome of same-session bilateral tubeless percutaneous nephrolithotomy (BPCNL) in supine and prone positions and to compare them to unilateral tubeless PCNL (UPCNL).
Materials and methods: Consecutive PCNL patients treated at two institutions between 2006-2016 were analyzed. Tubeless BPCNL was performed when indicated.
Results: Fifty-eight patients underwent BPCNLs [30 supine (SBPCNL) and 28 prone (PBPCNL)], while 1395 patients underwent UPCNLs. Demographics and baseline data were similar for all groups (p > 0.05). SBPCNL had a longer operating time (124 ± 38 minutes versus 105 ± 36 minutes; p = 0.49) and a significantly longer hospital… More >

Abstract Introduction: Costs of radiologic imaging are rising. The goal of this study is to examine the utilization practices of pediatric urologists who have access to in-office ultrasound imaging when managing children with primary hydronephrosis.
Materials and methods: A retrospective cross sectional study was performed of children ≤ 5 years old with an isolated diagnosis of hydronephrosis. Ultrasound utilization was evaluated by tallying the number of ultrasounds obtained during the time each child was followed. Imaging frequency was determined from orders given by each overseeing physician. Ultrasounds were performed at either the practitioner's clinic or at outside radiology… More >

Abstract Fibrous pseudotumors are rare benign lesions that originate within the paratesticular tissues. Local excision is the preferred method of treatment of these tumors over radical orchiectomy, however a definitive diagnosis must be made beforehand given the similarity of these tumors to malignant entities. We present a case of fibrous pseudotumor of the tunica vaginalis and cauda epididymis. A diagnosis of fibrous pseudotumor could not be established despite the use of intraoperative frozen section, therefore necessitating radical orchiectomy. More >

Abstract Gross hematuria is a common urologic problem which often requires surgical intervention. While generally a safe procedure, clot evacuation can have serious complications. Here we describe the case of an 85-year-old male who developed extensive subcutaneous emphysema following a small extraperitoneal bladder perforation during a clot evacuation. While our patient did well with expectant management, subcutaneous emphysema can lead to serious complications and any endourologic procedure should be stopped once crepitus is noted. More >

Abstract A 64-year-old man presented with a 2 week history of progressive phimosis and painful ulcer on his penile meatus. He underwent penile preserving excision, and subsequent pathological examination confirmed T-cell non-Hodgkin lymphoma with immunohistochemical features of large cell transformation of mycosis fungoides. The penis was further treated with local external beam radiotherapy consisting of 27 Gy in 15 fractions and systemic mini-CHOP chemotherapy. An organ-preserving tissue response has since been achieved. This case is the first of its kind in the literature and firmly highlights the role of multidisciplinary management for this rare malignancy. More >
