PURPOSE: This study aimed to evaluate technical success rate, complications, and radiation doses of ultrasound and fluoroscopy-guided percutaneous nephrostomy (PCN) in patients with nondilated renal collecting system.

METHODS: Over a 10-year period, 50 patients were referred for PCN of 60 kidneys with nondilated renal collecting system. The patients included 22 males and 28 females with a mean age of 63.2 years (range, 35–87 years). The most common reason for PCN in these patients was postoperative ureteral leaks and/or fistula (21/50 patients). PCN was performed under ultrasound and fluoroscopic guidance. During PCN, intravenous contrast media or diuretics were not used. Technical success rate, complications, procedure time, and radiation exposure of the procedure were retrospectively evaluated. 

RESULTS: Ultrasound and fluoroscopy guided PCN for nondilated renal collecting system showed a success rate of 83.3% (50/60 kidneys) in the initial attempt. Four PCNs were repeated and successful after the initial PCN failure. There was one major complication of bleeding that required transfusion in 1.9% (1/54) PCNs and there were minor complications of transient gross hematuria through the PCN catheter in 31.5% (17/54) PCNs. Mean duration of the procedure was 15.97±7.81 min and median fluoroscopy time was 4.2 min (range: 1.2–15.3 min). Median dose area product and cumulative dose were 345.37 μGy•m2 (range: 42.57–1659.76 μGy•m2) and 46.9 mGy (range: 7.7–267.8 mGy), respectively.

CONCLUSION: Ultrasound and fluoroscopy guided PCN for nondilated renal collecting system was feasible with acceptable technical success rate, complication rate, procedure time, and radiation exposure.
