Mp65-15 does Observation of Asymptomatic Treatment-Naive Renal Stones Impair Health-Related Quality of Life? -Results From the North American Stone Quality of Life Research Consortium

Abstract

All cases were reviewed and demographic data and case details were analyzed.RESULTS: 1000 consecutive aPNL cases were reviewed, identifying 488 men and 512 women, 460 right side and 535 left, mean age 57 years (15-86), mean BMI 30 (15-49), mean ASA of 2.3 (1-4) and mean stone burden 31 mm (4-170), mean fluoroscopy time 84 sec (0-322). Mean OR time was 95 min (32-305) and mean treatment time was 14.9 min (1-262). Mean PACU time was 91 min (37-247). A mini-PNL (mPNL) procedure was conducted in 255 (25.5%) patients. The remaining 745 cases were standard tract size of which 449 were 30Fr and 296 were 24Fr. Stone free rate was 83%. Thirty nine patients had complications ranging from Clavien II-IVa, of which 15 were hospital transfers.CONCLUSIONS: These consecutive 1000 cases may serve as a landmark series demonstrating the feasibility of aPNL. Transitioning PNL to an ambulatory setting is a paradigm shift in the treatment of complex kidney stones. 39 patients experienced complications of Clavien II or higher. Each complication that occurred was managed in an appropriate fashion and the site of service did not lead to an alteration in the outcomes of the adverse events. With an experienced surgeon, well trained operative team and with modifications to the procedure focusing on post-operative pain control, PNL can be safely and effectively performed in a free standing ASC. 1.
