ObjectiveTo report our results on percutaneous nephrostomy (PCN) and classify our complications with the Standard of Practice Committee of the Society of Interventional Radiology guidelines and the modified Clavien Classification System (CCS).MethodsThree hundred eighty-nine PCN insertions were performed in 322 patients (224 men and 98 women) at our institution. PCN insertion was performed under ultrasound for dilated pelvicalyceal system and ultrasound/fluoroscopy for nondilated system. PCN was considered successful if the catheter was drained urine spontaneously. Number of complications was registered.ResultsPrimary successful PCN insertion was achieved in 368 of the 389 procedures (94.6%). The success rates for nondilated and dilated systems were 82.7% and 96.4%, respectively. Major complications occurred in 9.6% and minor complications in 9.9% according to the Society of Interventional Radiology. According to the modified CCS grades I, II, III, IV, and V was 9.9%, 1.2%, 6.8%, 1.2%, and 0.3%, respectively. Age, grade of the hydronephrosis, serum creatinine levels, and mean hemoglobin levels were statistically significant parameters for the occurrence of complications on univariate analysis. The nondilated system has statistically significant parameters affecting the complication rates on multivariate analysis (P = .001, odds ratio [OR] = 6.1, 95% confidence interval [CI] = 2-18.4).ConclusionPercutaneous nephrostomy is a well-known procedure in the treatment of temporary or permanent drainage of an obstructed system. It is very important to define the complications related to interventions for interpretation of clinical comparisons more accurately. Modified CCS is a reproducible system to evaluate the complications.
