Popis: | Introduction et objectif : La NLPC est conventionnellement realisee en decubitus ventral. Cette position presente de nombreux inconvenients. Notre objectif etait d’evaluer de facon prospective le caractere sur et efficace de la NLPC en position de decubitus dorsal modifie (DDM). Materiel et methodes : Entre novembre 2004 et janvier 2010, 159 NLPC ont ete realisees en DDM. Le patient a ete mis en decubitus dorsal avec un billot sous le flanc permettant une rotation de 45 degres du cote oppose. Une position de lithotomie modifiee etait associee si un double acces anterograde et retrograde simultane etait necessaire. Apres ponction renale, la dilatation a ete faite selon la technique « one shot » ou en utilisant les dilatateurs d’Alken. Les caracteristiques des patients et des calculs, la duree operatoire, le sejour hospitalier, les complications et le taux d’absence de calculs residuels (« stone free ») ont ete analyses. Resultats : L’âge moyen des patients etait de 47 ± 13,1 ans (22–70). Vingt-et-un patients avaient des ATCD de chirurgie renale du meme cote. Vingt-six patients avaient un rein unique anatomique ou fonctionnel. Un patient avait un rein en fer a cheval et deux patients avaient une malrotation renale. Le diametre moyen des calculs etait de 3,4 ± 1,9 cm (1,3–5,4) et 20 patients avaient des calculs coralliformes. Dix patients avaient des calculs ureteraux et ont eu une ureteroscopie simultanee. La duree moyenne de l’intervention etait de 60 ± 29 min. Deux interventions ont ete interrompues en raison d’un saignement important. Trois cas de fievre postoperatoire et 2 cas de fistule urinaire traites par sonde en double J ont ete notes. Aucune plaie vasculaire ou viscerale n’a ete rapportee ni de plaie pleuropulmonaire. Huit patients ont eu une seconde seance de NLPC durant la meme hospitalisation. Apres trois mois le taux d’absence de calculs residuels etait de 91,8 %. Conclusion : La NLPC en DDM a permis de traiter de facon sure et efficace les calculs renaux. Elle a offert plusieurs avantages : facilite d’installation et non-necessite de changer la position, pas de compression thoracique, moins de contraintes anesthesiques, reduction du risque de plaie colique et possibilite d’acces simultane anterograde et retrograde. Purpose: Percutaneous nephrolithotomy (PCNL) is conventionally performed with the patient in the prone position. In this study, we assess the safety and efficacy of PCNL in the supine position. Methods: Between November 2004 and January 2010, we performed 159 percutaneous nephrolithotomies. The patient is placed in a supine modified position with an air bag underneath the operating flank. If necessary, a modified lithotomy position allowing the simultaneous antegrade and retrograde endourological access was used. The access has been realized with progressive Alken dilators or with the one-shot technique. Operative times, mean stay in hospital, complications and success rates were analyzed. Results: The mean age was 47 ± 13.1 years (range: 22-70). Twentyone patients had previous kidney surgery. Twenty-one had solitary kidneys and 3 patients had congenital renal abnormalities. The mean stone size was 3.4 ± 1.9 cm (range: 1.3-5.4). Twenty patients (29.5%) had complete staghorn stones. Ten patients (11.4%) also had ureteral stones and underwent concomitant ureteroscopy. The mean operative time was 60 ± 29 min, including patient positioning. In 2 patients it was necessary to suspend the procedure due to of bleeding. Postoperative complications included prolonged fever in 3 patients, nephrocutaneous fistula requiring double pigtail stent placement. Arterial embolization was never required. The colon was never damaged and we had no cases of hydrothorax or kidney loss. A second early treatment using the same percutaneous access during the same hospital stay was needed in 8 patients. The stone-free rate was 91.8%. Conclusions: Percutaneous nephrolithotripsy with the patient in a modified supine position is effective and safe. It offers obvious advantages from the point of view of the patient’s comfort and use of anesthetic. There is no risk of vitiated positions or traumatisms due to the change of bed-position and no thoracic compression occurs, which makes the procedure safe in patients with associated cardiorespiratory pathologies or obese patients. Also, the risk of colon perforation is reduced, which allowed for allows access to the entire urinary collecting system. |
