Differences in the percutaneous nephrolithotomy practice patterns among Latin American urologists with and without endourology training

Abstract

Purpose:Although the worldwide percutaneous nephrolithotomy (PCNL) practice pat- terns determined via a survey sent to members of the Endourological Society have been published, differences in PCNL practice patterns among Latin American urologists based on endourological or lithiasis training have not been published.To determine the PCNL practice patterns among Latin American urologists with and without training in endourology.Materials and Methods:The SurveyMonkey® web platform was used to develop a 27-item survey on PCNL for the treatment of renal stones, and the survey was sent via e- -mail and other electronic media to 2000 urologists from 15 Latin American countries. Endourology-trained (group 1) and nontrained urologists (group 2) were analyzed. The group results were compared using the chi-squared and Fisher's exact tests. SPSS version 20 for Windows was used for all analyses.Results:A total of 331 urologists responded to the survey (rate of 16.55%): 221 (66.7%) in group 1 and 110 (33.2%) in group 2). In groups 1 and 2, 91.9% and 63.2% performed PCNL, respectively: 85.1% and 58.5% used preoperative tomography, respectively; 12.7% and 4.7% used preoperative nephrolitometry nomograms, respectively: 45.2% and 32.1% used endoscopic combined intrarenal surgery, respectively: 68.3% and 38.7% used mul- tiple percutaneous tract realization, respectively: and 19.9% and 5.7% used minimally invasive PCNL, respectively (all p=0.0005).Conclusions:Statistically significant differences were observed in PCNL practice patterns of Latin American urologists with and without training in endourology. Specific training in endourology significantly influence the practice patterns of Latin American urologists.

Predictive factors for success after supine percutaneous nephrolithotomy: an analysis of 961 patients

“…Several factors influenced the previous underuse of supine PCNL, among them, the lack of experience in most urology centers 12 and the fear of colonic injuries. However, this scenario has been changing worldwide, and approximately 20% of centers use this technique currently 13 , reaching up to 45% in certain locations 14 and 38.9% in Latin America 15 . Any of the supine position variations do not have an impact on success or complications compared to the prone position 16 , and the supine position can be easily learned when training is done in a proper center.…”

Potential Risk of Calcified Nanoparticles for Recurrent Urinary Tract Infection after Minimally Invasive Percutaneous Nephrolithotomy for Renal Calculi

“…Under normal circumstances, the puncture point is under 12 intercostals and between 11 and 12 intercostals. After a successful puncture, pull out the inner core and see the urine flow out, detain the safety guide wire, take out the puncture needle, make a skin incision of 10 mm up and down here, use the expander to expand the channel to F16, and detain the expansion sheath at the same time to observe whether there is bleeding If not, channel 24F was continued to be dilated with an expanding sheath and an indwelling sheath (13)(14). If there is no special case, the ultrasonic probe is used for lithotripsy and aspiration at the same time, so as to shorten the operation time as much as possible.…”
