Technical and Therapeutic Results of the NLPC in the Treatment of Kidney Stones: Experience of the Urology Department of Military Instruction Hospital Mohammed V of Rabat: About 738 Cases

Abstract

Introduction: Percutaneous nephrolithotomy (PNLT) is a minimally invasive surgical technique for the treatment of large kidney stones. The aim of this study was to determine the place of NLPC in the treatment of renal lithiasis. Materials and Methods: In this retrospective study, we present our experience 738 cas de néphrolithotomie percutanée réalisés chez 646 patients dans le service d'urologie de l'hôpital militaire d'instruction Mohammed V de Rabat entre Janvier 2004 et décembre 2022. Results: There were 387 males and 259 females, the mean age of our patients was 46.1 years (11 - 70) with a sex ratio of 1.58. The lithiasis was pyloric in 322 cases (49.6%), inferior calcific in 189 cases (29%) and coralliform in 73 cases (11%). The therapeutic efficacy of NLPC was assessed at one and three months. 67.7% of our patients were stone free. The main complications we encountered were haemorrhage (36 cases). Conclusion: NLPC has become the treatment of choice for pyelic, calcific and pyelocalcific calculi unresponsive to LEC. It has supplanted open surgery. Technological innovation and the ingenuity of urologists have improved efficacy and reduced morbidity.
