Postoperative outcomes: good (stone-free): 14 cases (50%), pretty good (residual fragments < 5 mm): 6 cases (21.4%), mediocre (residual fragments > 5 mm, multiple fragments): 8 (28.6%) in which 4 cases had extracorporeal shockwave lithotripsy one month postoperatively, 3 cases had second look 1 - 2 weeks postoperatively for removal of residual fragments, 1 case had second look and extracorporeal shockwave lithotripsy. Conclusions: PNL for staghorn calculi remains a sophisticated renal procedure.
