Percutaneous Nephrolithotomy in Horseshoe Kidney Our 5-Year Experience

Purpose: To review our 5-year experience in percutaneous nephrolithotomy (PCNL) for horseshoekidney with large stone burden or failed shockwave lithotripsy (SWL).Materials and Methods: During 5 years (2006 to 2011), PCNL was performed on 21 patientswith horseshoe kidney stone. We evaluated patients (age and gender), stones characteristics (size,number, side, and site), surgical technique, and outcomes.Results: Sixteen (76.16%) subjects were men and 5 (23.80%) were women, with the mean age of35 ± 12 years. Mean stone size was 37.2 ± 16.6 mm. Percutaneous nephrolithotomy was performedbecause of the stone size (over 20 mm) in 18 (85.68%) and failed SWL in 3 (14.28%) subjects.Stone numbers were more than one in 18 (85.68%) subjects, and were in the pelvis and at least onecalyx. The most common access site was superior posterior calyx (66.64%). Stone-free rate withsingle session and rigid nephroscope was 71.40%. No major complication occurred during the surgeryor in post surgical period. Postoperative minor complications occurred in 3 (14.28%) patients,including transfusion in one (4.76%), fever in one (4.76%), and ileus in one (4.76%) subject.Conclusion: Percutaneous nephrolithotomy has acceptable results in horseshoe kidney stone and isfeasible with rigid nephroscope.
