Objective: We aimed to investigate the effect of hydronephrosis on operative duration, dilata-tion duration, fluoroscopy time, stone free state and bleeding upon percutaneous nephrolitotomy (PNL).
Materials and Methods: Data of 405 pati-ents underwent PNL in our clinic between Janu-ary 2009 and December 2012. The patients were divided into three groups as no hydronephrosis (Group 1), low degree hydronephrosis (Group 2), high degree hydronephrosis (Group 3-4). Three groups were compared according to operative pa-rameters.
Results: Group 1 consisted of 120, group 2 consisted of 160 and group 3 consisted of 125 pa-tients. Mean patient age was 47,76±15,14, 42,31 ±15,06 and 49,05±11,50 for Groups 1,2 and 3 res-pectively. All groups had similar previous ope-ration history, access technique, stone locali-zation and stone load. Flouroscopy times were 5,45±3,74 ,6,14±4,39 and 6,41±4,08 minutes for Groups 1, 2 and 3 respectively. Duration for guidewire axcess was 8,63±5,79, 5,58±3,5 and 3,32±1,82 minutes for Groups 1, 2 and 3 respec-tively (p<0,001). For Group 1, 2 and 3, mean ir-rigation fluid volume used for the operation was 11,81±4,12 lt, 10,25±4,20 and 12,26±2,80 lt, res-pectively (p<0,001)
Conclusion: Preoperative hydronephrosis does not seem to have an effect on operative time, fluoroscopy duration or bleeding. Stone free state decreases with preoperative hydronephrosis, but dilatation duration decreases. We believe hydronephrosis facilitates access.
