Objective: This study was designed to compare the efficacy and safety of the supine and prone positions in percutaneous nephrolithotomies (PCNLs) used for the treatment of kidney stones in Indonesian patients. Methods: This was a single-blinded randomized controlled trial of those patients undergoing PCNLs from February to May of 2018. There were 19 subjects in the supine group and 19 in the prone group for a total of 38 study subjects. The study outcomes that were compared included the operative time, hospital length of stay (LOS), stone-free rate, blood loss, conversion to open surgery, blood transfusion, and complications. These outcomes were evaluated using the Student’s t test and the chi-squared test. Results: There were no significant differences in the patient demographics or stone locations between the two groups. Additionally, the medians of the operative times, LOSs, blood losses, and blood transfusions were not statistically different. There was a higher stone-free rate in the supine group than in the prone group (70.0% vs. 47.4%, respectively, p = 0.151). More subjects were transfused in the supine group (30.0%) than in the prone group (15.8%), but this difference was not statistically significant (p = 0.292). The only complications were infundibular lacerations, which occurred in 20% of the subjects in the supine group and 15.8% of the subjects in the prone group (p = 0.732). Conclusion: This study showed that the supine and prone positions for PCNLs had similar efficacy and safety outcomes.

Summary Objective: To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). Method: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications). Results: The mean stone size was 12.23 +/- 5.43 mm (range 6-22mm), located in the inferior (58.33%) and middle (16.76%) calyceal units, renal pelvis (16.67%) and multiple locations (8.33%). All 13 patients were treated with Ho-Yag laser, using dusting technique (25%), fragmentation and extraction of the calculi (58.33%) and mixed technique (16.67%). We did not have any severe perioperative complication. After 90 days, nine patients (75%) were considered stone free. Conclusion: Our data suggest that F-URS is a safe and feasible choice for the treatment of kidney stones in patients with renal ectopic and fusion anomalies.

Purpose To clarify the outcome of flexible ureteroscopy (fURS) for management of renal calculi without preoperative stenting. Methods A total of 171 patients who received 176 fURS procedures for unilateral renal stones were reviewed. All procedures were divided into two groups depending on whether they received ureteral stenting preoperatively. Baseline characteristics of patients, stone burden, operation time, stone-free rates, and complications were compared between both groups. Results Successful primary access to the renal pelvis was achieved in 104 of 114 (91.2%) patients without preoperative stenting, while all procedures with preoperative stenting (n = 62) were successfully performed. A total of 156 procedures were included for further data analysis (56 procedures in stenting group and 100 in non-stenting group). No significant differences was found regardless of a preoperative stent placement in terms of stone-free rate (73.2% with stenting vs. 71.0% without, P = 0.854), operative time (70.4 ± 32.8 with stenting vs. 70.2 ± 32.1 without, P = 0.969). Conclusions fURS for management of renal stone without preoperative ureteral stenting are associated with well outcome in short term follow-up. Our study may help patients and doctors to decide if an optional stent is placed or not.
