An Analysis on Sensor Locations of the Human Body for Wearable Fall Detection Devices: Principles and Practice.

Wearable devices for fall detection have received attention in academia and industry, because falls are very dangerous, especially for elderly people, and if immediate aid is not provided, it may result in death. However, some predictive devices are not easily worn by elderly people. In this work, a huge dataset, including 2520 tests, is employed to determine the best sensor placement location on the body and to reduce the number of sensor nodes for device ergonomics.

Intrarenal Surgery vs Percutaneous Nephrolithotomy in the Management of Lower Pole Stones Greater than 2 cm.

Purpose: To compare the efficacy of RIRS and PNL in lower pole stones ≥ 2 cm. Materials and and Methods: A total of 109 patients who underwent PNL or RIRS for solitary lower pole stone between April 2009 and December 2012, were retrospectively analyzed. Lower pole stone was diagnosed with CT scan.

Diagnostic significance of biopsies in renal masses.

Introduction: We investigated the reliability and mapping of percutaneous needle core biopsies in the kidney in histopathological diagnosis of renal masses particularly for those with suspicious radiologic appearance in an attempt to prevent unnecessary nephrectomies.

Material And Methods: Overall, 96 cases were included in our study that underwent radical nephrectomy or partial nephrectomy due to renal mass between November 2007 - March 2010. Ex-vivo biopsies 1 cm apart were obtained from the peripheral region of the mass.

What is the best radiological method to predict the actual weight of the prostate?

Aim: We compared the weight of the prostate specimen extracted after radical prostatectomy with preoperatively estimated weights of the prostate by different imaging techniques.

Materials And Methods: Prostate weights were estimated by transabdominal ultrasonography (TAUS), transrectal ultrasonography (TRUS), and computed tomography (CT) preoperatively before radical prostatectomy. Prostatectomy specimens were weighed postoperatively and the actual prostate weights were calculated.

Is there a correlation between intravaginal ejaculatory latency time and enuresis? An exploratory study.

Introduction: Premature ejaculation (PE) is the most common male sexual dysfunction. Monosymptomatic enuresis (ME) is nocturnal bed wetting, without any daytime symptoms. Recent clinical studies report an association between lifelong PE and ME.

The incidence of postoperative ileus in patients who underwent robotic assisted radical prostatectomy.

Introduction: Our aim was to examine the incidence and risk factors of postoperative ileus among patients who underwent robot-assisted radical prostatectomy (RARP).

Material And Methods: We retrospectively reviewed 239 patients who underwent RARP transperitoneally between February 2009 and December 2011. Patients switched to open surgery were excluded.

Detecting falls with wearable sensors using machine learning techniques.

Falls are a serious public health problem and possibly life threatening for people in fall risk groups. We develop an automated fall detection system with wearable motion sensor units fitted to the subjects' body at six different positions. Each unit comprises three tri-axial devices (accelerometer, gyroscope, and magnetometer/compass).

Robot-assisted laparoscopic nerve-sparing radical cystoprostatectomy with bilateral extended lymph node dissection and intracorporeal studer pouch construction: outcomes of first 12 cases.

Purpose: We report our initial experience with robot-assisted laparoscopic neurovascular bundle (NVB) sparing radical cystoprostatectomy (RALRC), bilateral extended lymph node dissection (BELND) with intracorporeal Studer pouch construction for invasive bladder cancer.

Patients And Methods: After initially performing >50 cases of robot-assisted laparoscopic radical prostatectomies (RALRP), between December 2009 and April 2010, we performed 12 RALRC procedures with BELND. Bilateral (n=10) and unilateral (n=1) intrafascial NVB preservation was performed in 11 patients; nonnerve-sparing RALRC was performed in 1 patient.

The incidence and management of pleural injuries occurring during open nephrectomy.

Objective: To evaluate the incidence, management, and risk factors of pleural injuries occurring during open nephrectomy.

Methods: Between June 2004/and June 2008, 165 patients (167 renal units) underwent open simple (n = 37, 22.2%), partial (n = 39, 23.

Incorporation of anterior rectus fascial sling into radical retropubic prostatectomy improves postoperative continence.

Aim: To determine the impact of rectus fascial sling suspension at the time of radical retropubic prostatectomy (RRP) on postoperative continence status.

Patients And Methods: A total of 86 patients underwent RRP for clinically localized prostate cancer. Out of 86 patients, a rectus fascial sling procedure was incorporated into RRP in 40 randomly selected patients (group 1).

Testis sparing surgery for sequential bilateral testicular tumors.

Objective: We present our experience in performing testis sparing surgery (TSS) to treat sequential bilateral testicular tumors.

Material And Methods: We performed TSS on two patients with bilateral sequential testicular tumors.

Results: A 43-year-old patient (Case 1) and a 33-year-old patient (Case 2) had previous inguinal orchiectomy for seminoma.

Ileal ureteral replacement in a man with Studer pouch.

Use of a bowel segment for ureteral replacement is a reliable and a feasible procedure with satisfactory results. We present a patient with a complete left ureteral necrosis due to infection; with an abscess formation in the retroperitoneum after a radical cystoprostatectomy and Studer pouch operation.

Factors affecting urethral stricture development after radical retropubic prostatectomy.

Objective: We determined the factors that can cause urethral stricture after radical retropubic prostatectomy.

Materials And Methods: A total of 56 patients underwent radical retropubic prostatectomy for clinically localized prostate cancer between June 2004 and July 2006. The patients were invited for cystography and removal of the urethral catheter at the 7th postoperative day if no extravasation was seen.
