Resultados funcionales de la pieloplastia laparoscópica pura y asistida por robot

Abstract

The management of ureteropelvic junction (UPJ) obstruction has evolved over the past 20 years in response to the development of new technology. Open surgery is still the reference standard against which all other surgical interventions must be measured. The surgical approach has, however, gone through rapid changes, and the open procedure initially described has evolved considerably. Endoscopic and laparoscopic approaches have largely supplanted open pyeloplasty for the majority of primary ureteropelvic junction obstruction cases. Laparoscopic approaches provide a balance between a highly successful technique in all patients and improved postoperative recovery. It has been shown to improve postoperative outcomes with shorter recovery times and hospital stays, and to provide equivalent functional results with a success rate of 95%. Nevertheless, laparoscopic pyeloplasty is not a simple procedure. There are a certain number of disadvantages, such as the limited range of laparoscopic instrument movement, the two dimensional image, the unfamiliar hand-eye coordination and the relatively inefficient ergonomic position. Since 2000, however, robots have provided a magnified three-dimensional view giving a greater degree of freedom. This system has simplified suturing and has improved precision of the operating technique. However, the system is very expensive and, providing it is available in their institution, it seems easier for beginners to learn the robotic technique. Additionally, it has similar success rates (both radiological and clinical) to those obtained with open techniques.

Evolution in the treatment of the ureteropelvic junction obstruction syndrome. Laparoscopic versus open pyeloplasty

“…Also, this approach may be limited in some categories of patients such as the obese. All of these difficulties have led to the development of minimally invasive techniques over past last twenty years [ 1 , 8 – 15 ].…”

“…Since Schuessler et al in 1993 described the first laparoscopic pyeloplasty (14) this procedure has evolved in order to achieve the same results as open surgery, with lower rates of morbidity and complications [ 7 , 8 , 15 ]. Laparoscopic pyeloplasty may be done using transperitoneal or retroperitoneoscopic approach.…”
