Urinary Drainage

Extra-Anatomic Urinary Drainage for Urinary Obstruction

Long-term drainage of the urinary tracts of patients with impassable ureteric strictures remains a major challenge to the urologist. Until the mid 1970’s the only viable, minimally invasive treatment was a permanent nephrostomy with all its sequelae, loss of quality of life, risk of tube dislocation, infection, and recurrent obstruction (Marberger, 2006). For decades, researchers experimented w...

Access, Stents, and Urinary Drainage

Ureteral access is necessary in many endourological procedures including ureteroscopy and ureteral stenting. Technologies such as ureteral access sheaths, balloon dilators, and coaxial dilators may be helpful in facilitating ureteral access in difficult cases. This chapter describes a stenting technique that relies on fluoroscopic guidance once the initial guidewire is placed and the cystoscope...

The mythical danger of rapid urinary drainage.

Renal Physiology Control of Urinary Drainage and Voiding

Urine differs greatly in ion and solute composition from plasma and contains harmful and noxious substances that must be stored for hours and then eliminatedwhen it is socially convenient to do so. The urinary tract that handles this output is composed of a series of pressurizable muscular compartments separated by sphincteric structures. With neural input, these structures coordinate the deliv...

Best practice for patient self-cleaning of urinary drainage bags.

The best practice for cleansing urinary drainage bags (leg and bed) in a hospital setting can be translated for use by clients for self-care within the home setting. Common household bleach containing 5.25% sodium hypochlorite, diluted in a 1:10 ratio with tap water, is a safe and effective method to reduce colony-forming units per milliliter (CFU/ml) to a study-defined acceptable range of 100 ...
