•Investigate the impact of residents’ laparoscopic surgical skills training on the successful implementation of Laparoscopic partial nephrectomy in a reference public teaching hospital in southern Brazil.•The results of our study strongly suggest that the use of simulation training to urology residents improved perioperative performance and most importantly was associated with an improvement in Trifecta rates.•Through this study we proved that the use of simulation training is also valid for the learning of complex surgeries such as laparoscopic partial nephrectomy. Partial nephrectomy (PN) is the preferred modality of treatment for small renal masses. Laparoscopic partial nephrectomy (LPN) has been adopted worldwide and a fundamental role is played by surgical skills. The need for skill instruction outside the operating room is well recognized in the modern models of surgery residency training. We aim to investigate the impact of residents’ laparoscopic surgical skills training on the successful implementation of LPN in a reference public teaching hospital in southern Brazil. We accessed all patients undergoing LPN by senior's urology residents at Hospital de Clínicas de Porto Alegre. Patients were stratified in 2 periods of time named ‘LPN eras’ 1 and 2, to report the training impact on the outcome. LPN era 1 was from October 2012 to February 2017 and LPN era 2 from March 2017 to June 2019. All the senior residents of LPN era 2 followed a simulation training divided into 4 years with a total training time of 244 hours before performing the LPN. Residents from LPN era 1 did not have simulation training. 124 patients underwent LPN during the study period, 53 (42.7%) of those were performed in LPN era 1 and 71 (57.3%) in LPN era 2. Baseline characteristics of the patients in the two groups were similar. The training performed by LPN era 2 residents was able to significantly reduce estimated blood loss, ischemia time and LOS with p value respectively 0.007, 0.001 and 0.001. LPN era 2 group also reached Trifecta in 77.5% of patients, being significantly more than in the LPN era 1 (p = 0.007). Simulation in residents surgical training was able to improve clinical outcomes in LPN. These data reinforce the fundamental importance of adequate residents training before performing surgery on a patient.
