Event Description

As reported in the literature article, "urologist directed percutaneous nephrostomy tube placement," a cook cope-loop nephrostomy set became occluded after placement.The authors report the following: "a retrospective review of 100 consecutively placed nephrostomy tubes in 18 patients (53 women and 29 women) was done.All nephrostomy tubes were placed by house staff under the supervision of a single attending urologist.Varied nephrostomy tubes were used to gain experience with a range of drainage systems."patients were placed in the prone position with the knees flexed and all pressure points padded for nephrostomy tube insertion.Percutaneous access was routinely obtained with a 17.5 gauge angiomed 3-part initial puncture needle under ultrasonic guidance with a 3.5 mhz transducer.Preliminary ultrasonic imaging identified adjacent bowel and other internal organs.Knowledge of the approximate distance from the skin to the collecting system helped estimate needle puncture depth and, in addition, malrotated kidneys and renal hilar vessels were appreciated.Ultrasonic visualization of the puncture needle was maintained during insertion.Appropriate placement of the tip of the puncture needle also was confirmed by the efflux of urine and/or injection of radiocontrast material into the collecting system."a floppy j-tipped guide wire was placed into the collecting system and down the ureter when possible.Fascial dilation developed an appropriately sized tract.The nephrostomy tube then was placed over the guide wire into the collecting system.Contrast medium was injected under fluoroscopic imaging to define the anatomy, confirm proper nephrostomy tube placement and exclude any associated injuries.All tubes were secured directly to the skin with 2-zero nylon sutures and simple 4x4 gauze dressings.An additional fixation point with tape was placed approximately 20cm.From the insertion site to help prevent twisting and kinking of the tube before connection to a closed gravity collection device.When cope tubes were used the tip was coiled in the renal pelvis with the pull-string.Balloon retention catheters were inflated with dilute contrast medium to confirm position.Immediate and delayed complications associated with nephrostomy tube placement were identified, and a detailed clinical assessment was done." ¿nephrostomy tubes (100) were placed in 29 women and 53 men.A range of different nephrostomy tube alternatives was used during the review period, reflecting a desire on our part to identify superior methods of nephrostomy access to limit procedure related and delayed drainage complications.We used 47 single j, 28 cook-cope, 11 rush nephrostomy, 9 foley urinary, 3 malecot and 1 rubber robinson urinary catheters and 1 argyle chest tube.¿ "complications related to the nephrostomy tubes were assessed as being either early (involved in catheter placement and becoming clinically apparent within 24 hours) or late (becoming apparent more than 24 hours after insertion).A total of 27 complications was noted in 14 patients." "nephrostomy tube occlusion occurred in 3, 10f single j catheters, 1 10f cope tube and 2 foley catheters (16f and 18f).Occlusion appeared to be directly related to the viscosity of drainage, with purulent material being present in 5 of the 6 cases." cited: mahaffey, k.G., bolton, d.M., stoller, m.L.(1994).Urologist directed percutaneous nephrostomy tube placement.The journal of urology, 152, 1973-1976.Https://doi.Org/10.1016/s0022-5347(17)32282-6.
