ABSTRACT
We reviewed records of patients with ESRD in all dialysis and kidney transplant centers of Guilan province to determine the incidence and modalities for treatment of ESRD from 2005 to 2007. Records of 759 patients were reviewed during the 3-year period of the study. The male-female ratio was 1.34:1 and the men age at the time of diagnosis was 56.3 +/- 16.8 years. The most frequent age group was 60 years and older (45.8%). The incidence ESRD during 2005, 2006, and 2007 were 100.36 pmp, 100.60 pmp, and 110.66 pmp, respectively. The most common causes of ESRD were hypertension (29.4%), unknown (26.6%), and diabetes mellitus (17.9%). The most common modality at initiation of renal replacement therapy was hemodialysis (96.0%). The entrance rate of hemodialysis in 2005, 2006, and 2007 were 29.6%, 35.0%, and 35.4%, and the discontinuing rate of hemodialysis in these years were 29.5%, 32.1%, and 38.4%, respectively.

BACKGROUND AND PURPOSE: In this study we aimed to determine the effects of previous open renal surgery on the results and complications of subsequent percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: From October 2005 to October 2007, 104 patients underwent PCNL in our hospital. We compared the patients who undergone previous open surgery on the same kidney (group 1; n = 36) with those who had undergone no previous surgery (group 2; n = 68). We extracted requested information such as age, sex, stone number, stone burden, intraoperative and postoperative complications, hospital stay, access time, operative time, and success rate. The results of the study were analyzed using SPSS 10 software. RESULTS: Intraoperative complications were seen in 11.11% of the group 1 patients and in 11.8% of the group 2 patients. Postoperative fever was seen in 33.3% of the patients in group 1 and in 26.5% of the patients in group 2. Mean hospital stay was 85.88 +/- 17.25 hours and 80.20 +/- 17.71 hours in group 1 and group 2, respectively. Mean operating time was 75.41 +/- 17.2 minutes in group 1 and 67.42 +/- 26.25 minutes in group 2. Stone-free rate was 88.9% in the group 1 patients and 79.4% in the group 2 patients. Step 1 access time in group 1 and group 2 was 120.02 +/- 68 seconds and 117.80 +/- 80.52 seconds, respectively (p = 0.002). CONCLUSIONS: PCNL in patients who previously underwent open renal surgery is effective and safe. We found no difference in results between the two groups based on the number of stones and the number of accesses. The step 1 of dilatation was the only difference between the two groups.
