ABSTRACT

Aim:

The increased mortality and morbidity in diabetic patients who underwent cardiac surgery is well documented. However, there are few data about non-cardiac surgical interventions. This study is designed to evaluate whether diabetes has any effects on outcome of percutaneous nephrolithotomy (PNL).

Methods:

The records of 1658 patients who underwent PNL between October 2002 and December 2009 in our clinic were retrospectively analyzed. Data of patients with diagnosis of diabetes mellitus (group 1, 231 patients) were compared with data of patients without diabetes (group 2, 1427 patients) by means of operative and postoperative findings.

Results:

Complete stone clearance was achieved in 206 (89.1%) patients in group 1 and 1355 (94.9%) patients in group 2 (p:0.000). Auxiliary treatment modalities were needed in 44 (19.0%) diabetic and 153 (10.7%) non-diabetic patients (p:0.000). In diabetic patients, operation and hospitalization time, and time of nephrostomy tube removal were significantly longer. In addition, bleeding, fever and urosepsis rates were significantly higher in diabetic patients.

Conclusion:

PNL in diabetics is an effective procedure with acceptable complication rates in the treatment of renal stones. However, the increased risk of bleeding and infection needs extra attention in diabetic patients when compared with non-diabetics.
