The Use of the da Vinci SP System for Retzius-sparing Radical Prostatectomy in Cadaveric Model.

Objective: To evaluate the use of a new single-port robotic system, da Vinci SP (Intuitive Surgical, Sunnyvale, CA) in performing retzius-sparing radical prostatectomy in a cadaveric model.

Methods: A cadaver was placed in supine position on operating table. A 4-cm skin incision was made above the umbilicus for insertion of the robotic port via a GelPoint Mini Advanced Access Platform (Applied Medical, Rancho Santa Margarita, CA).

The cardiovascular risk factors in men with lower urinary tract symptoms.

Objective: It has been hypothesized that endothelial dysfunction and pelvic atherosclerosis may contribute to lower urinary tract symptoms (LUTS). We assessed the relationship between cardiovascular risk factors and LUTS severity in male patients presented to urology clinic.

Methods: It is a cross-sectional study on patients who presented between 2013 and 2015 with LUTS.

Monopolar vs. bipolar transurethral resection for non-muscle invasive bladder carcinoma: A post-hoc analysis from a randomized controlled trial.

Purpose: Traditionally, transurethral resection of bladder tumors (TURB) is performed using monopolar technique. Bipolar resection has been postulated to reduce complications. In this study we compare safety and efficacy between monopolar TURB (mTURB) and bipolar TURB (bTURB) for patients with primary non-muscle invasive bladder cancer (NMIBC).

Prostatic artery embolization in treating benign prostatic hyperplasia: a systematic review.

Introduction: We systemically reviewed the current evidence on prostatic artery embolization (PAE) in treating men with benign prostatic hyperplasia.

Methods: A systemic literature search was conducted in PubMed, EMBASE and Web of Science on 1 May 2016 without time constraints. Outcomes of interest included the changes in the International Prostate Symptom Score (IPSS), quality-of-life (QOL) score, peak urinary flow (Qmax), post-void residual urine (PVR), International Index of Erectile Function (IIEF) score, prostate volume (PV) and prostate-specific antigen (PSA) level.

Cell-free urinary microRNA-99a and microRNA-125b are diagnostic markers for the non-invasive screening of bladder cancer.

Background: Evidence implicated the diagnostic significance of microRNAs in whole urine/urine sediments in urothelial carcinoma of the bladder (UCB). However, the contaminated blood cells in patients with haematouria significantly altered the expression profiles of urinary microRNA, influencing the test accuracy.

Methods: MicroRNA profiles of the urine supernatants of UCB patients and controls without any malignancy and profiles of malignant and corresponding normal mucosa tissues from the patients were determined by microRNA microarray and compared to identify differentially expressed microRNAs.

Current management practice for bladder cancer in Hong Kong: a hospital-based cross-sectional survey.

Objectives: To examine current practice in the management of bladder cancer in Hong Kong government and private hospitals.

Design: Cross-sectional survey.

Setting: All government hospitals and the major private institutions in Hong Kong, which provide urological services.

The prevalence of lower urinary tract symptoms in a Chinese population, and the correlation with uroflowmetry and disease perception.

Objectives: To evaluate the prevalence of lower urinary tract symptoms (LUTS) in a population of Chinese men, and its correlation with uroflowmetry and disease perception.

Materials And Methods: Male volunteers above 40-year old were recruited in the community. Assessment with International Prostatic Symptom Score (IPSS), uroflowmetry, and a quiz on prostatic disease knowledge with 12 true-false-type questions were performed.

Clinical outcomes of augmentation cystoplasty in patients suffering from ketamine-related bladder contractures.

Objective: To evaluate the outcomes of augmentation cystoplasty in patients with bladder contractures secondary to chronic ketamine abuse.

Method: Patients who had received augmentation cystoplasty to treat ketamine-related bladder contractures in two hospitals in our region were reviewed retrospectively. Their history of ketamine consumption, presenting symptoms, history of treatment, surgical information and post-operative conditions were retrieved from clinical records and then summarized.

In vivo targeted contrast enhanced micro-ultrasound to measure intratumor perfusion and vascular endothelial growth factor receptor 2 expression in a mouse orthotopic bladder cancer model.

Purpose: We evaluated the feasibility of using targeted contrast enhanced micro-ultrasound imaging to assess intratumor perfusion and vascular endothelial growth factor receptor 2 expressions in a mouse orthotopic bladder cancer model.

Materials And Methods: We created an orthotopic mouse model by implanting MBT-2 murine bladder cancer cell lines in the bladder of syngeneic C3H/He mice (Jackson Laboratory, Bar Harbor, Maine). Successful tumor implantation was confirmed by transabdominal micro-ultrasound imaging on post-implantation day 11.

Pneumovesicum approach to en-bloc laparoscopic nephroureterectomy with bladder cuff excision for upper tract urothelial cancer: midterm oncological results.

Introduction: We reported the pneumovesicum (PV) approach to lower ureter and bladder cuff excision and closure. We believe that this approach bears the closest resemblance to the laparoscopic skill set of intravesical dissection and suturing. Herein, we report the midterm oncological results of the approach's use in a series of patients with upper tract urothelial cancer.

Using urine microscopy and cytology for early detection of bladder cancer in male patients with lower urinary tract symptoms.

Objectives: Irritative urinary symptoms and micro-hematuria are the common findings in bladder cancer patients. In this study, we investigated the use of urine microscopy and cytological examination for early detection of bladder cancer in patients with lower urinary tract symptoms (LUTS).

Methods: Male patients presented with LUTS to urology clinic were enrolled.

Primary bladder amyloidosis--case report of a patient with delayed upper urinary tract obstruction 3 years after the diagnosis.

Primary bladder amyloidosis is a rare disease. There are approximately 100 reported cases. The lesions can be confused with bladder neoplasm and are characterised histologically by the classical apple green birefringence under polarised light.

Optimizing orthotopic bladder tumor implantation in a syngeneic mouse model.

Purpose: We established a reliable technique for orthotopically implanting bladder tumor cells in a syngeneic mouse model.

Materials And Methods: MBT-2 murine bladder cancer cells were transurethrally implanted in the bladder of syngeneic C3H/He mice (Jackson Laboratory, Bar Harbor, Maine). Different chemical pretreatments were used before tumor implantation, including phosphate buffered saline (control), HCl, trypsin and poly-L-lysine.

Transabdominal micro-ultrasound imaging of bladder cancer in a mouse model: a validation study.

Objectives: To validate the use of transabdominal micro-ultrasound imaging (MUI) in an orthotopic murine bladder cancer model. The current in vivo imaging systems for murine bladder cancer include magnetic resonance imaging, bioluminescent and fluorescent imaging, and intravesical ultrasound.

Methods: We implanted murine bladder tumor-2 tumor cells into C3H/He female mice.

Novel approach of laparoscopic transperitoneal en bloc resection of urachal tumor and umbilectomy with a comparison of various techniques.

Urachal carcinoma is a rare cancer that accounts for less than 1% of all bladder cancers. Surgical resection remains the mainstay of treatment. With partial cystectomy, long-term survival is possible following complete resection of the tumor.

Cystinuria: a rare diagnosis that should not be missed.

Cystinuria is a rare autosomal recessive defect causing recurrent urinary tract stone formation. Morbidity from stone formation and repeated urological interventions can be reduced by early diagnosis and adequate medical treatment. In this review, we illustrate these points by discussing three patients with cystinuria and give a brief review of its management.
