[Percutaneous nephrostomy under echographic guidance. Apropos of 31 cases]
Insights
Percutaneous nephrostomy (P.C.N.) placement was successful in all 31 patients. While minor complications occurred, major issues like hemorrhage and septicemia were rare, indicating P.C.N. is a viable option for urinary tract obstruction.
Area of Science:
- Urology
- Interventional Radiology
Background:
- Percutaneous nephrostomy (P.C.N.) is a key interventional radiology procedure.
- Indications include upper urinary tract obstruction and ureteral fistulas.
Purpose of the Study:
- To evaluate the efficacy and safety of P.C.N. under combined ultrasound and fluoroscopic guidance.
- To detail the indications and potential complications of P.C.N.
Main Methods:
- 31 P.C.N. procedures were performed using real-time ultrasound and fluoroscopic guidance.
- Complications were documented and categorized as major or minor.
Main Results:
- No failures in nephrostomy tube placement were observed.
- 13 complications occurred in 9 patients: 3 major (1 hemorrhage, 2 septicemia) and 10 minor (tube displacement).
- P.C.N. facilitates ureteral antegrade catheterization.
Conclusions:
- P.C.N. is an effective procedure for managing upper urinary tract obstruction and ureteral fistulas.
- The complication rate is acceptable, with major complications being infrequent.
- P.C.N. has significant applications in interventional uro-radiology.
Abstract:
31 percutaneous nephrostomies (P.C.N.) were realised under a combination of real time ultrasound and fluoroscopic guidance. No failure in placement of the nephrostomy tube was noted. 13 complications were noted in 9 patients: 3 were major, consisted in 1 severe hemorrhage and 2 septicemia and 10 were minor, mainly caused by secondary displacement of the tube. Three indications of P.C.N. are related to upper urinary tract obstruction: 1) Overdistension and fever or pain associated with poor patient's condition. 2) Short-term obstructions. 3) Diagnosis of the nature or location of the obstruction when other techniques don't provide the solution, and/or evaluation of renal function. The drainage of some ureteral fistules represent the fourth indication. P.C.N. allows ureteral antegrad catheterization and its applications. Results are discussed and present or future applications of interventional uro-radiology are related.
