Risk Assessment for BK Virus-Associated Hemorrhagic Cystitis After Pediatric Hematopoietic Stem Cell Transplant: A Single-Center Retrospective Cross-Sectional Study.

Objectives: BK virus-associated hemorrhagic cystitis is a common complication of allogeneic hematopoietic stem cell transplant. It is known to be associated with cyclophosphamide therapy and the intensity of the conditioning regimen as well as infection with the BK virus. Data are limited for BK virus-associated hemorrhagic cystitis in pediatric recipients of allogeneic hematopoietic stem cell transplant.

The role of RENAL, PADUA and C-index scoring systems in predicting the results of partial nephrectomy without ischemia.

Objective: To evaluate the feasibility and renoprotective effect of off-clamp partial nephrectomy (PN) by renal scoring systems.

Methods: After approval of the local ethics committee, the radiological and clinical data of patients with renal masses who underwent PN between January 2012 and January 2017 were evaluated in two university hospitals. Total 132 patients who underwent open surgery and off-clamp technique were included.

Microdissection testicular sperm extraction (micro-TESE): Predictive value of preoperative hormonal levels and pathology in non-obstructive azoospermia.

The aim of this study was to evaluate the predictive value of preoperative hormonal levels and pathology, as well as the outcome of microsurgical testicular sperm extraction in patients with non-obstructive azoospermia (NOA), presenting to our clinic for treatment of infertility. The records of 145 men with NOA who underwent microdissection testicular sperm extraction (micro-TESE) between March 2013 and November 2016 were studied. The patient's age, testicular volume, hormonal profile for follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (TT), and testicular pathology were recorded.

Safety and efficacy of photoselective vaporization of the prostate using the 180-W GreenLight XPS laser system in patients taking oral anticoagulants.

Objective To evaluate the safety and efficacy of the 180-W GreenLight XPS laser system for the treatment of benign prostatic hyperplasia in patients taking oral anticoagulants. Methods All consecutive patients admitted for lower urinary tract symptoms associated with benign prostatic hyperplasia from November 2012 to October 2016 and who underwent photoselective vaporization of the prostate with the 180-W GreenLight XPS laser were included in the study. The perioperative outcomes examined were the operating time, laser time, energy usage, and duration of postoperative catheterization.

Computed tomography based evaluation of prostatic fiducial marker migration between the periods of insertion and simulation.

Objective: The aim of this study was to determine whether significant fiducial marker migration occurs between the periods of prostatic marker insertion and computed tomography (CT) performed for radiotherapy planning and if a waiting period is necessary.

Material And Methods: Thirty-nine patients with prostate adenocarcinoma underwent fiducial marker insertion before radiotherapy between June 2013 and December 2015. Three markers were inserted by one radiologist under the guidance of transrectal ultrasonography.

Bilateral recurrent external obturator muscle hematoma: An unusual cause of pelvic pain in hemophilia.

Following joint hemorrhages, intramuscular hemorrhages are the second most prevalent bleeding pattern in hemophiliac patients. Hematomas of the iliopsoas muscle are a well-known complication of hemophilia; however, obturator muscle hematomas are rare. We herein report a case of spontaneous bleeding of the bilateral external obturator muscles, which occured three times within a period of 9 months in a hemophilia patient with factor VIII inhibitors.

Effect of obesity on International Prostate Symptom Score and prostate volume.

Aim: The aim of this study was to investigate the relationship between obesity and lower urinary tract symptoms and prostate volume in patients who underwent prostate biopsies.

Materials And Methods: Between December 2008 and November 2009, transrectal ultrasound-guided prostate biopsy was performed on patients who had elevated prostate-specific antigen levels or abnormal digital rectal examination findings. A total of 211 patients were included in this study.

Safety, efficacy and outcomes of the new GreenLight XPS 180W laser system compared to the GreenLight HPS 120W system for the treatment of benign prostatic hyperplasia in a prospective nonrandomized single-centre study.

Introduction: We compare and evaluate the safety, efficacy, and short-term outcomes of the new GreenLight XPS 180W (GL-XPS) laser system with the former generation GreenLight HPS 120W (GL-HPS) system for the treatment of benign prostatic hyperplasia (BPH) in a prospective nonrandomized single-centre study.

Methods: From May 2012 to June 2013, 161 consecutive patients with lower urinary tract symptoms secondary to BPH were included: 88 patients were treated with the GL-HPS system and 73 were treated with the GL-XPS system. The perioperative variables International Prostate Symptom Score (IPSS), quality of life (QOL), and maximum flow rate (Qmax) were recorded at baseline, at one month and 6 months.

Spontaneous rupture of the ureter.

Spontaneous rupture of the ureter is a very rare condition and usually results from ureteral obstruction by a calculus. Only theoretical mechanisms have been proposed and no possible explanation has yet been reported in the literature. Intravenous contrast-enhanced computed tomography is the most informative study with high sensitivity.

Primary perivascular epithelioid cell tumour (PEComa) of the prostate.

Perivascular epithelioid cell tumours (PEComas) are a family of rare mesenchymal tumours arising in various anatomic locations. PEComas are defined by the presence of perivascular epithelioid cells that coexpress muscle and melanotic markers, especially HMB-45. They have unpredictable biological behaviour and are mostly benign, but some tumours can become unresectable or metastatic.

The effect of garlic powder on human urinary cytokine excretion.

Purpose: To evaluate the effects of orally administered dehydrated garlic powder on cytokine excretion in the urinary tract.

Materials And Methods: A total of 60 healthy volunteers, randomized into 3 groups, were given a single oral dose of 1 g or 3 g of dehydrated garlic powder or placebo. Urine samples were obtained 6.

Emphysematous cystitis: The role of CT imaging and appropriate treatment.

Emphysematous cystitis is a relatively rare disease characterized by the presence of gas in the bladder wall and/or lumen. The primary risk factor is diabetes mellitus. Emphysematous cystitis should be considered in cases of urinary tract infections in diabetic patients with unusual presentations.

An unusual cause of hematospermia: Primary adenocarcinoma of the seminal vesicle.

Adenocarcinoma of the seminal vesicles is one of the rare causes of hematospermia. Primary seminal vesicle adenocarcinoma is extremely rare and difficult to diagnose due to frequent invasion of adenocarcinomas of the surrounding organs, especially the prostate. In the present study, a case of a primary seminal vesicle adenocarcinoma will be discussed in the light of the current literature.

Acute urinary retention due to cystic echinococcosis: A case report.

Urinary hydatidosis is very rare and represents 2% to 4% of all cases of cystic echinococcosis. We present a case of a 21-year-old man with symptoms of frequency, urinary retention and reduced force in urinary stream due to cystic echinococcosis. Anti-Echinococcus granulosus antibodies were determined by echinococcosis western blotting, and pelvic computed tomography revealed a 11 × 14 × 10-cm retrovesical homogeneous cystic mass.

Immunohistochemical and electron microscopic examination of Cajal cells in ureteropelvic junction obstruction.

Objective: We examine the ultrastructural configurations of Cajal cells by electron microscopy, as well as the quantitative changes occurring in Cajal cells by light microscopy.

Methods: In total, 35 patients with ureteropelvic junction (UPJ) obstruction and 7 patients without obstruction were compared immunohistochemically with c-kit (CD117) to quantify the number of cells. On electron microscopic examination, 7 patients with UPJ obstruction and 3 patients without obstruction were compared to evaluate the changes which occurred in the ultrastructural configuration of the Cajal cells.
