Epidemiological and clinical profile of urinary tract infections in patients with percutaneous nephrostomy tubes, about 117 cases

Abstract

INTRODUCTION:

The installation of a nephrostomy is one of the elementary gestures in urology often carried out within the framework of the emergency for a vital indication. Nephrostomy carries a number of risks and complications. Among these complications, we describe the frequently reported infection that may be secondary to poor hygiene care.

Goals :

 Describe the epidemiological aspects of urinary tract infections in patients with nephrostomy catheters in the urology department of chu Ibn Rochd, determine their clinical characteristics, establish their bacteriological profile and then study the sensitivity of the bacterial strains isolated to antibiotics.

Materials and methods :

This is a retrospective work on 117 cases with nephrostomy catheters and presenting a urinary tract infection during their follow-up at the urology department of the chu ibn rochd casablanca from January 1, 2019 to December 31, 2019.

Results:

The average age of patients is 50.5 years (17–84 years). There was a male predominance with Sex ratio M / F 1.55. The main indication was acute obstructive renal failure secondary to bladder tumor in 34 patients, or 29%, followed by ARIO secondary to cervical cancer in 29 cases, or 25%. main germs Escherichia coli (32%), Proteus mirabilis (12%) and Enterobacterfecalis (7%). The sensitivity study showed alongside natural resistance, low sensitivity to Ampicillin (32%), Amoxicillin + Clavulanic acid (39%), moderate sensitivity to Quinolones 78%, nitrofurans 62% and trimethoprim 51% and a high sensitivity to aminoglycosides 92% (amikacin and gentamicin), to imipenem 96% and Colistin 98%.

Conclusion:

 This study suggests the need for the implementation of rigorous nephrostomy procedures ensuring compliance with good practices and thus limiting the risk of urinary tract infection which can endanger renal function.
