Sacral bladder denervation for treatment of detrusor hyperreflexia and autonomic dysreflexia

2001

Objectives. Detrusor hyperreflexia after spinal cord injury may cause urinary incontinence and chronic renal failure. In patients refractory to conservative treatment and not eligible for ventral sacral root stimulation for electrically induced micturition, we investigated the therapeutic value of sacral bladder denervation as a stand-alone procedure. Methods. Nine patients (8 men and 1 woman) between 21 and 58 years old (mean 30.2) with traumatic suprasacral spinal cord lesions underwent sacral bladder denervation for treatment of detrusor hyperreflexia and/or autonomic dysreflexia. Results. Detrusor hyperreflexia and autonomic dysreflexia were eliminated in all cases. Bladder capacity inc…

Dislodgement in Long-Term Patients with Nephrostomy Tube: Risk Factors and Comparative Analysis Between Two Catheter Designs

2020

Objective: To determine possible risk factors for accidental nephrostomy tube dislodgement and compare two different tube types in this context in patients with chronic catheters. Materials and Met...

Major urinary dysfunction after mesorectal excision for rectal carcinoma

2004

Abstract Background Urinary dysfunction may occur after mesorectal excision and pelvic autonomic nerve preservation (PANP) in patients with rectal carcinoma. The aim of this prospective study was to identify factors predictive of long-term urinary catheterization. Methods Two hundred and ten patients without significant urological problems underwent resection of rectal cancer with mesorectal excision. The number of patients with complete, partial or no identification of the nerves was documented and correlated with possible predictive factors for postoperative major urinary dysfunction. Results Eight patients (3·8 per cent) required long-term urinary catheterization: two after complete PANP…

Simplified Orthotopic Ileocecal Pouch (Mainz Pouch) for Bladder Substitution

2003

Objective To report operative modifications that render construction of the orthotopic Mainz pouch more simple, namely formation of the pouch using absorbable staples and utilization of the ileocecal valve as an antireflux mechanism. Patients and methods Between January 2001 and May 2002 out of 92 cystectomy cases, 21 patients (20 males and 1 female) underwent a simplified orthotopic Mainz pouch. The ureters were implanted via Wallace or Nesbit technique in the supravalvular portion of the ileocecal valve. The mean (range) age was 58 (43 - 74) years and the mean follow-up is 11.6 months (range 1 - 27). Results No staple-related complications were encountered. Four renal units (8.8 %) were d…

Predictors of clinical events occurring during hospital stay among elderly patients admitted to medical wards in Italy.

2016

Abstract Background Clinical events occurring during hospital stay are independent predictors of prolonged hospitalization, in-hospital mortality and readmission among elderly patients admitted to medical wards. Purpose To identify predictors of intercurrent clinical events (ICE) during hospital stay among the main demographic, functional and clinical characteristics assessed at hospital admission in a multicenter sample of elderly inpatients in Italy. Methods This observational prospective cohort study was conducted in 66 internal and geriatric medicine hospital wards in 2010. It enrolled 1267 inpatients aged 65 years or older living at home before hospitalization. Multivariable Poisson re…

Study of three urethral pressure recording devices: Theoretical considerations

1978

Using a bladder-urethra model, 2 perfusion catheters (open side and open tip) were compared to the balloon catheter. The most accurate results were obtained using the balloon catheter. Based on the law of continuity and Bernouilli's law, the disadvantage of the open side catheter is due to the inconstant diameter of the sum of the side holes. Therefore, the measured pressure is not necessarily identical to the real pressure. The open tip catheter measures the opening pressure and the recorded pressure does not necessarily reflect the pressure at the site of the tip hole. The balloon catheter has elastic and plastic characteristics. Optimum results were obtained only with prestretch of the b…

Predictive factors for Enterococcus faecalis in complicated community‐acquired urinary tract infections in older patients

2019

AIM Risk factors for complicated community acquired Enterococcus faecalis urinary tract infection (UTI) in older patients are not well known. METHODS We identified the predictive factors for E. faecalis on a cohort of 659 older patients admitted to hospital with complicated UTI. We also examined the adequacy of empirical antimicrobial therapy and outcomes in E. faecalis UTI. Multivariable logistic regression was used to identify predictors of E. faecalis UTI. RESULTS A total of 87 (13.2%) patients had E. faecalis UTI; of these 63.2% were men, their mean age was 82.3 years and they had a great number of comorbidities. Severe sepsis or septic shock was present in 50.5%, and bacteremia was pre…

Predictive variables of spontaneous micturition recovery after acute urinary retention in men with benign prostatic enlargement: An observational pro…

2017

Objective: Acute urinary retention (AUR) is the sudden and painful inability to urinate spontaneously. AUR is one of the most significant complications of benign prostatic enlargement. The management of AUR is based on transurethral catheterization. Subsequent therapy is uncertain, but AUR seems to benefit from the use of alpha-blockers. The aim of this study was to evaluate the variables that could predict which patients would recover spontaneous micturition after trial without catheter. Methods: The present prospective observational study included men with AUR in an Italian tertiary care institute in 2016. Patients were catheterized and treated orally with fluoroquinolones, alpha-blockers…

A High Throughput, Minimally Invasive, Ultrasound Guided Model for the Study of Catheter Associated Urinary Tract Infections and Device Encrustation …

2014

Purpose Catheter associated urinary tract infections are one of the most common health care associated infections. The condition is frequently complicated by encrustation, which blocks the catheter lumen. Preclinical research is limited by the lack of relevant high throughput and cost-effective animal models. Current models are restricted to female mice, associated with major transurethral loss of catheter materials during micturition, highly invasive and complex. We present an ultrasound guided, minimally invasive model that enables catheter associated urinary tract infection and catheter encrustation studies in each mouse gender. Materials and Methods Catheter segments (4 mm) were implant…
