[Disinfection of endoscopic equipment]

All the endoscopy equipment are generally thermo sensitive requires a sensitive high-level disinfection instead of sterilization. Disinfection techniques are classified into three levels of action: low, intermediate and high. This later should cover the most resistant types of microorganisms namely spores. This disinfection should follow good practices, thus we have audited some units and we have established an inventory of current practice with respect to such disinfection standards. We evaluated 12 units that use endoscopy equipment by using a questionnaire that has been established taking into account the 5M Ichikawa diagram. However, our study showed that currently the endoscopy equipment is not disinfected according to standards due to negligence or technical shortage. In this assessment, some weaknesses were identified in the current practice of such disinfection. These weaknesses affect several levels: the methodology, personnel, material, equipment and the environment. The endoscopy equipment requires rigorous disinfection and must comply with good practices. We should deploy the necessary of human and material resources to disinfect these devices and contribute to fight against nosocomial infections

[Place of percutaneous nephrolithotomy in the treatment of kidney stones]

This is a minimally invasive surgical technique, which has its place as a first intention treatment of urolithiasis. Our object is to insist on the importance of this technique within the therapeutic arsenal of renal lithasis. This is a retrospective study of 300 cases of percutaneous nephrolithotomiers practiced in 270 patients in our department through a period of 23 years [1985-2008]: It concerned includes x 157 males and 113 females, the average age is 46 years old [17 years-75] - The calulus was pelvic in 188 cases [62.7%], lawer calyceal in 52 cases [17.3%] and a staghorn in 40 cases [13,3%]. All our patients were treated by the sawe technique. Our success rate was of 68,7%, the complications concerned zo cases that is a rate of 6.7%, without any deaths. The operation duration average was 188 minutes, and the postoperative hospitalisation period was seven days. The percutaneous ne phrolithotomy restes a recommended firts intention in the treatment of complex calculus in association with the complementary extracorporal lithority. The classical surgery has its place in the percutaneous nephrolithotomi failure cases, the residual calculus are the prerogative of extractor poreal lithoripsy
