Choosing the nephrostomy size after percutaneous nephrolithotomy.
Summary of "Choosing the nephrostomy size after percutaneous nephrolithotomy."
To evaluate the effect of nephrostomy tube size on perioperative outcomes of percutaneous nephrolithtotmy (PCNL).
Forty-five well-matched patients with normal renal function were prospectively divided in two nonrandomized groups after uneventful PCNL (to receive either a 22-Fr, group 1 (n = 24 pts), or a 12-Fr nephrostomy tube, group 2 (n = 21 pts)). In all a balloon nephrostomy catheter with detachable funnel (Rüsch Teleflex, Germany) was used. A Visual Analogue Scale (VAS) for measuring the pain was administered 8 and 24 h after the procedure. Postoperative analgesics use (Ketoralac Tromethamine 30 mg), pre- and postoperative Hb, renal function and urinary leaks were registered.
Groups were comparable as demographics and stone characteristics. VAS pain score was significantly higher in group 1 (4.25 vs. 3.2, P < 0.001) only 8 h postoperatively. No significant difference was found in the VAS pain score 24 h p.o. Similarly, analgesics use (1.6 vs. 1.1, P = 0.05), sHb (1.42 vs. 1.21, P = 0.055) and hospital stay (3.8 vs. 3.6, P = 0.63) were not significant between the two groups of patients.
A small bore nephrostomy catheter may reduce pain in the immediate postoperative time. It does not affect blood loss and hospital stay so it can safely be used instead of a large size nephrostomy tube, after uneventful percutaneous procedures.

Medical and Biotech [MESH] Definitions
The insertion of a catheter through the skin and body wall into the kidney pelvis, mainly to provide urine drainage where the ureter is not functional. It is used also to remove or dissolve renal calculi and to diagnose ureteral obstruction.
Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.
Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation. In addition to standard surgical removal, it can be performed by percutaneous diskectomy (DISKECTOMY, PERCUTANEOUS) or by laparoscopic diskectomy, the former being the more common.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
The process of choosing employees for specific types of employment. The concept includes recruitment.
PURPOSE: To explore the relationships between nephrostomy tube (NT) size and outcome of percutaneous nephrolithotomy (PCNL). METHODS: The Clinical Research Office of the Endourological Society (CROES)...
PURPOSE: Traditionally the placement of a nephrostomy tube at the conclusion of percutaneous nephrolithotomy is considered the standard of care. However, the need for nephrostomy tube placement has be...
This study was conducted to compare nephrostomy-free percutaneous nephrolithotomy (PCNL) with early nephrostomy tube removal (after 1 day). A prospective study started from January 2008 through Decem...
OBJECTIVES. (1) To evaluate the safety and efficacy of supine percutaneous nephrostomy, nephrolithotomy, and combined percutaneous nephrolithotomy and ureteroscopic lithotripsy. (2) To describe the sk...
The study is unique in terms of defining the safety of totally tubeless percutaneous nephrolithotomy (PNL). Furthermore, the authors state that the tubeless group has an advantage of less pain. Howeve...
The investigators are trying to determine whether placement of a nephrostomy tube prior to definitive stone surgery and under ultrasonic or fluoroscopic guidance will reduce complications...
The purpose of this study is to determine whether continuous intravenous ketorolac infusion reduces pain in patients who are having percutaneous nephrolithotomy for kidney stone disease.
Patients with large or otherwise complex renal calculi are commonly treated by percutaneous nephrolithotomy (PNL; PERC). PERC requires the creation of an approximately 10 mm channel throu...
The investigators main hypothesis is that the stone free rate will be much higher (95%) in patients treated with PCNL than patients treated with ESWL where stone free rate is (60%) to dete...
Percutaneous nephrolithotomy (PNL), in conjunction with intracorporeal lithotripsy, allows for the rapid removal of any kidney stone regardless of size. Currently, the choice of intracorp...
