Ultrasonically Guided Percutaneous Nephrostomy

Scandinavian Journal of Urology and Nephrology, 1990
Ultrasonically guided percutaneous nephrostomy was planned in 98 patients with a total of 128 nephrostomies. The success rate was over 90%. The catheters were maintained from a 1/2 day to 150 days with a median duration of 13 days. 26% of the patients had the catheter replaced, mainly because of displacement.

Percutaneous Nephrostomy and Ureteral Injury

Journal of Urology, 1981
The courses of 6 patients with various forms or ureteral injury and disruption herein illustrate the value and worth of percutaneous nephrostomy drainage and study. The nature and degree of injury are ascertained, and sepsis and obstruction are managed without formal anesthesia or surgical intervention, leading to ultimate repair in a planned and ...

A New Method for Percutaneous Nephrostomy

Radiology, 1976
A new method of percutaneous nephrostomy using techniques to place a No. 12 French balloon catheter in the renal collecting system is described. Case reports demonstrate tumor palliation and temporary drainage to improve the very ill prior to definitive surgery.

Percutaneous Nephrostomy

2016
Percutaneous nephrostomy is a minimally invasive method for the external drainage of the upper urinary tracts, performed under ultrasonographic or fluoroscopic guidance. The purpose of the method is, first, to decrease the pressure and distension of the pyelocaliceal system, together with gaining an antegrade access to the upper urinary tract to ...

Do's and don't's of percutaneous nephrostomy

Academic Radiology, 1999
Percutaneous nephrostomy procedures generally are safe. The associated mortality rate is approximately 0.04%, and the incidence of important complications is 5% (2-4). To minimize complications, certain precautions always should be followed. First, radiologists should perform a preprocedural evaluation of the patient, with correction of marked ...

Percutaneous Nephrostomy with Immediate Dilation

Journal of Urology, 1981
Percutaneous nephrostomy may serve as an alternative to an open operation for urinary diversion. Difficulties with poor drainage and premature catheter dislodgement have prompted the development of a technique for dilation of the needle tract and placement of a large, self-retaining catheter at the time of the initial puncture.

Percutaneous nephrostomy in infants and children

American Journal of Roentgenology, 1983
Percutaneous nephrostomy drainage was established in 28 children, predominantly for ureteric obstruction. Infection was the most frequent presenting feature (nine patients) followed by renal failure (six) and a combination of the two (four). A sonographically guided antegrade examination was first performed with a 22-gauge needle.

Introducer Needle for Percutaneous Nephrostomy

Urologic Clinics of North America, 1990
A new introducer needle that prevents tracking facilitates rapid and predictable entry into the chosen posterior calix with minimal use of fluoroscopy for lithotripsy or renal drainage. This device should make it possible for urologists and radiologists to acquire rapidly the skill to access the kidney in virtually all patients.
