To access the safety and efficacy of tubeless percutaneous nephrolithotomy (PCNL). Since January 2001, 1000 consecutive tubeless PCNLs performed at our hospital were enrolled into this retrospective chart review. The average age of the patients (659 males and 341 females) was 54.4 ± 12.6 years, and 55 patients were 75 years old or older. The stone characteristics were 490 non-complete staghorn kidney stones, 218 ureteral stones, 119 kidney + ureteral stones and 173 complete staghorn stones. The mean stone size was 3.5 ± 2.0 cm, and 200 patients had stone size ≥5.0 cm. The average operative time was 78.0 ± 29.4 minutes. The stone free rates were 78.8%, 100%, 84.9% and 45.0% for kidney, ureter, kidney + ureter and complete staghorn stones, respectively, with an overall stone free rate of 78.3%. The average postoperative hospital stay was 3.6 ± 2.1 days, and the blood transfusion rate was 2.4%. Postoperative fever was noted in 104 patients, and urosepsis was noted in 13 patients. Pulmonary complication included hydrothorax in 5 patients, hemothorax in 2 patients, pneumothorax in 2 patients and acute pulmonary edema in 1 patient. Cadiovascular complications included congestive heart failure in 1 patient and pneumomediastinum in 1 patient. Our study demonstrated that sith adequate hemotasis, tubeless modification is a safe modality for PCNL.
