ABSTRACT

Background: Percutaneous nephrostomy was first used in 1955, as a urinary diversion method, and became more commonplace in the nineteen-seventies as a means of access for endourological procedures. Today, the primary indication for this procedure is still obstructive uropathy, observing a rate of complications of 30-50% when there is dilation. However, there is a group of patients in whom the indication to perform the procedure is not obstruction, with conditions such as extracorporeal shock wave lithotripsy, endourological procedures, or treatment of emphysematous pyelonephritis, although no specific studies have been conducted to study incidence in that sub-group.
Objective: To describe the frequency of early complications in percutaneous nephrostomies performed in patients without hydronephrosis.
Method: A retrospective, observational, descriptive study of the general frequency of early complications of percutaneous nephrostomies in patients without hydronephrosis. We will present a description of independent variables by age group, gender, and medical indication warranting the procedure. We will describe the different complications observed (dependent variables) and their relationship with the medical indication. All the results will be expressed in absolute and relative frequency due to the type of study.
Results: The absolute frequency of presentation of complications was nine cases in 17 (52%), of which the primary complication was dissection in four cases (44.4%) and the main indications associated with complication were emphysematous pyelonephritis and uretheral fistula (100%).
Conclusion: In general, the study shows high frequency of complications in this sub-group of patients; however, they were all mild and had no clinical repercussions, which shows that it is a safe study despite its technical difficulty.
