ABSTRACT

Objective:

The aim of this study was to evaluate the effectiveness and safety of percutaneous nephrolithotomy (PNL) in the patients with previous open renal surgery.

Material and Methods:

976 patients who underwent PNL between 2003-2013 were evaluated retrospectively. The patients were divided into two groups based on whether they have previous surgery on the ipsilateral kidney or not. 160 patients (% 60 male, % 40 female; average age 41.7) who had previous open renal surgery were categorized in group 1, while 816 patients with no history of surgery (% 55 male, % 45 female; average age 38,6) took part in group 2. Two groups were compared in terms of stone burden, percutaneous access number, operation time, length of hospital stay, success rate and complications.

Results:

There was no significant difference in terms of age, gender and stone burden (p>0.05). The average operation time in group 1 was 77,7 and in group 2 was 75,1; the average percutaneous access number was 1.27 and 1.33 respectively and the average length of hospital stay was 3.0 and 2,9 respectively (p>0.05). The stone free rate in group 1 was % 86 and in group 2 was % 88 (p>0.05). The most common complication in both two groups was blood transfusion requiring bleeding (% 6,8 and % 6,3 respectively) followed by fever above 38°C (% 9.1 and % 11,2 respectively). There was no significant difference between two groups in terms of these complications (p>0.05).

Conclusion:

Percutaneous nephrolithotomy is a safe and effective procedure that can be applied to the patients with previous renal surgery as well as to the patients having no previous surgery.
