    PURPOSE To investigate the safety and efficacy of the imaging-guided percutaneous nephrostomy (PCN) procedure in infants. METHODS A total of 75 (50 boys; 66.7%) patients with a mean age of 121 days (range, 1–351 days) who underwent PCN over a period of 20 years were included in this retrospective study. For each patient, PCN indications, catheter size, the mean duration of catheterization, complications, and the procedure performed following nephrostomy were recorded. Technical success was determined based on the successful placement of the nephrostomy catheter within the pelvicalyceal system. Clinical success was defined as the complete resolution of hydronephrosis and improvement in renal function tests during follow-up. In patients with urinary leakage, technical and clinical success was determined based on the resolution of leakage. RESULTS The technical success rate was 100%, and no procedure-related mortality was observed. In 11 patients (14.7%), bilateral PCN was performed. The most frequent indication of PCN was ureteropelvic junction obstruction (n = 41, 54.7%). Procedure-related major complications were encountered in two patients (methemoglobinemia and respiratory arrest caused by the local anesthetic agent in one patient and the development of urinoma caused by urinary leakage from the puncture site in the other). Mild urinary leakage was the only minor complication that occurred and only in one patient. Catheter-related complications were managed through replacement or revision surgery in 16 patients (21.3%). CONCLUSION Imaging-guided PCN is a feasible and effective procedure with high technical success and low major complication rates, and it is useful for protecting kidney function in infants.

    Radiologically guided percutaneous nephrostomy: A 6-year single-center experience
    (2019) Şeker, Mehmet; Çiftçi, Türkmen Turan; Akıncı, Devrim; Akhan, Okan
    Aim: To retrospectively analyze the indications, underlying pathologies, technical success rate, complications and benefit of percutaneous nephrostomies in a single centre. Materials and Methods: Data of 578 patients who underwent radiologically guided percutaneous nephrostomy between January 1999 and December 2004 were retrospectively reviewed. The mean age of the patients was 42.5 years (range, 6 days–90 years). The indications were urinary obstruction without urinary infection (77.9%), urinary obstruction with urinary infection (13.1%), urinary diversion (6.9%) and diagnostic testing (2.1%). Results: The technical success rate was 99.4%. There was no procedure related mortality. Major hemorrhage or sepsis were not observed in children. Major hemorrhage occurred in 1.55% and sepsis occured in 2.65% of adult patients. Catheter dislodgement was the commonest complication with an overall rate of 11.4%. In 7.2% patients, percutaneous nephrostomy was successful in managing patients without further intervention. 36.5% of patients had surgery and 14.7% had ureteral stenting as definitive treatment. Conclusion: Radiologically guided percutaneous nephrostomy, can be used effectively, and safely in a wide variety of indications with high technical success and low complications rates.
