Pyeloplasty laparoscopic outcomes in the National Center of Minimal Access Surgery

Abstract

Introduction: Pyeloureteral obstruction is the restriction of urine flow from the renal pelvis to the ureter, causing pyelocaliceal dilation that if not treated evolves into progressive deterioration of renal function. It is known as Pyeloureteral Junction Syndrome (PJS). The treatment is surgical and the Anderson-Hynes dismembered technique has shown the best results. It has been described through laparoscopic approach. Objetives: To show the results of laparoscopic pyeloplasty, its feasibility and its success rate. Methods: A descriptive and longitudinal study was made of 31 patients with PJS treated at the National Center of Minimal Invasive Surgery (NCMIS) Centro Nacional de Cirugía por Mínimo Acceso (CNCMA) between July 1st 2010 and January 31st 2014 with the purpose of describing its results. Demographic variables were considered which assess the technique and its feasibility. A transperitoneal approach was carried out, anastomosis with intracorporeal discontinue suture and pelvis remodeling with continuous suture and a JJ catheter was placed retrogradely. Results: The male sex, the right side, the extrinsic cause were predominant. The technique was 100% feasible. The assessing variables of the results of the surgical technique corresponded to what has been described by other authors. There were no transoperative complications, 29 % postoperative; three grade IIIb and one grade IVa according to Clavein-Dindo Classification. In 93,5 % the technique was successful. Conclusions: Laparoscopic pyeloplasty at the (CNCMA) is a feasible alternative of treatment for PJS adult patients, with an acceptable success rate and morbility.
