BACKGROUND: There is no clear consensus as to the optimal method of entry in laparoscopic renal surgery and no reports have compared them in Urology. To analyze contemporary practice patterns in entry technique and port placement for laparoscopic kidney surgery. METHODS: We identified 60 high volume urological laparoscopic centers. A purpose-built questionnaire was sent to surgeons. The survey included 22 questions regarding access techniques and port configuration during laparoscopic kidney surgery. Data on were collected and retrospectively analyzed. Concordance among port configurations was assessed using Cohen's Kappa statistics. RESULTS: The survey was sent to 60 surgeons and completed by 32 of them. Surgical procedures included were laparoscopic radical nephrectomy (1177 LRN/year) and laparoscopic partial nephrectomy (1047 LPN/year). The transperitoneal route was preferred (85%). Hasson technique was used for the access in 55% of the cases. Patient lateral recumbent position is the most frequently used during the port placement (41%). Although there is a high variability in the port positioning among the surgeons, in more than 90% of cases it was found a specific concordance in triangulation of optics and operating trocars. There were no significant differences between port configuration in LRN and LPN. Limitations include retrospective design and limited sample. CONCLUSIONS: A standard port configuration has not been previously reported in urological literature. Our study suggests that the transperitoneal approach, the Hasson technique and a specific triangulation of optics and operating trocars have a significant concordance in some high volume laparoscopic urologic centers.
