Objective: To evaluate the stone free rates of kidney and ureter stone patients managed by Extracorporeal Shockwave Lithotripsy (ESWL), and the ureter stone free rate managed by ureterolithotripsy. Material & method: We reviewed the medical records of kidney and ureter stone patients managed by ESWL and ureter stone patients managed by ureterolithotripsy in Arifin Achmad Regional General Hospital Pekanbaru Riau Province, Indonesia, from January 2010 - December 2016. ESWL and ureterolithotripsy stone free rates were examined by the control of KUB röngents. Results: There were 891 kidney and ureter stone patients consisting of 325 (36.5%) were kidney stone patients and 566 (63.5%) were ureter stone patients. The pyelum stones were the most (78.2%) in kidney stones and the lower ureter stones were the most (57.2%) in ureter stones. There were more male patients than the female ones in which most of the patients were in the group age of 49-59 years. The amount of patients increased each year. The kidney stone free rate managed by ESWL was lower (71.7%) than ureter stone free rate (84.1%) by ESWL, while the stone free rate of ureter stone patients managed by ureterolithotripsy was 100%. Conclusion: The ESWL stone free rate of the kidney stone patients was lower than the one in ureter stone patients while the ureterolithotripsy stone free rate was 100%.

Objective: To compare the stone free rates on patients with staghorn, renal pelvic, and inferior calyx stones with stone burden < 20 mm, 21-30 mm, and > 30 mm following percutaneous nephrolithotomy (PCNL) in Cipto Mangunkusumo General Hospital Jakarta. Material & methods: The data were collected retrospectively from PCNL medical records in Cipto Mangunkusumo General Hospital Jakarta between January 2000 and March 2011. Six hundred and twenty-three patients with 651 kidney stones underwent PCNL. The inclusion criteria were staghorn stones, renal pelvic stone, and inferior calyx stone. All cases outside these three criteria and incomplete data were excluded. Stone free status was defined as no residual fragment on radiography or ultrasonography. Results: As many as 364 kidney stones from 344 patients were included, with 47.8% cases of staghorn stones, 31.9% cases of renal pelvic stones, and 20.3% cases of inferior calyx stones. Overall, 273 (75%) cases were defined as stone free. In group < 20 mm, 4 staghorn stones (100%), 18 renal pelvic stones (81.8%), and 34 inferior calyx stones (94.4%) were cleared (p = 0.811). In group 21-30 mm, 20 staghorn stones (95.2%), 52 renal pelvic stones (91.2%), and 26 inferior calyx stones (92.9%) were cleared (p = 1.000). In group > 30 mm, 83 staghorn stones (55.7%), 28 renal pelvic stones (75.7%), and 8 inferior calyx stones (80%) were cleared (p = 0.037). Conclusion: PCNL is an important tool for treating various kinds and sizes of kidney stones with high stone free rate.

Objectives: To compare the effectiveness and complications of ureteroscopic laser lithotripsy with laparoscopic ureter laparoscopic ureterolithotomy in mid- or proximal portion of large ureteral stones. Material and Methods: We reviewed patients with large (>15 mm) ureteral stone and those who underwent ureteroscopic laser lithotripsy (URS group) or laparoscopic ureterolithotomy (LU group). The first attempt was considered successful in patients who had residual fragments smaller than 2 mm and no conversion of the primary procedure to another. Results: Sixty patients (URS group 29, LU group 31) met inclusion criteria. FURS was used as an adjunctive procedure in one patient for URS group and in two patients for LU group in the same season. LU had a higher success rate and the first-day stone-free rate when compared with URS. Number of procedures was also significantly higher in URS group. There was no difference in stone-free rates at the first and third months, and length of hospitalization and operation were higher in the LU group. Only two patients in the LU group and one patient in the URS group had major complications. Conclusions: Laparoscopy is an effective option of large proximal and mid-ureter stone treatment; however, URS provides similar stone-free rates at three months as a minimal invasive procedure.

Abstract Background The R.I.R.S. scoring system is defined as a novel and straightforward scoring system that uses the main parameters (kidney stone density, inferior pole stones, stone burden, and renal infundibular length) to identify most appropriate patients for retrograde intrarenal surgery (RIRS). We strived to evaluate the accuracy of the R.I.R.S. scoring system in predicting the stone-free rate (SFR) after RIRS. Methods In our medical center, we retrospectively analyzed charts of patients who had, between September 2018 and December 2019, been treated by RIRS for kidney stones. A total of 147 patients were enrolled in the study. Parameters were measured for each of the four specified variables. Results Stone-free status was achieved in 105 patients (71.43%), and 42 patients had one or more residual fragments (28.57%). Differences in stone characteristics, including renal infundibulopelvic angle, renal infundibular length, lower pole stone, kidney stone density, and stone burden were statistically significant in patients whether RIRS achieved stone-free status or not (P < 0.001, P: 0.005, P < 0.001, P < 0.001, P: 0.003, respectively). R.I.R.S. scores were significantly lower in patients treated successfully with RIRS than patients in which RIRS failed (P < 0.001). Binary logistic regression analyses revealed that R.I.R.S. scores were independent factors affecting RIRS success (P = 0.033). The area under the curve of the R.I.R.S. scoring system was 0.737. Conclusions Our study retrospectively validates that the R.I.R.S. scoring system is associated with SFR after RIRS in the treatment of renal stones, and can predict accurately.

Objective. We aimed to investigate the role of antegrade irrigation via percutaneous nephrostomy on surgical outcomes in retrograde ureteroscopy in patients with upper ureter stones. Materials and Methods. In this retrospective study, we analyzed 134 patients who underwent retrograde semirigid ureteroscopy for upper ureter stones between August 2012 and December 2017. Patients were divided into two groups: retrograde irrigation group (conventional URS) and antegrade irrigation group (using percutaneous nephrostomy). Operation time, postoperative hospital stay, complications, and stone-free rate were measured for each patient after ureteroscopy. Results. The mean age in the retrograde irrigation and antegrade irrigation groups was 53.3 and 60.7 years, respectively (p=0.007). The operation time was 60.8 min vs. 43.0 min (p=0.002), and stone-free rate was 82.0 % vs. 95.5 % (p=0.033). Stone size, laterality, the proportion of male patients, and urinary tract infection prevalence were comparable between the groups. In the subgroup analysis of stone size >10 mm, the antegrade irrigation group had a shorter operation time and a higher stone-free rate. For stone size of 5–10 mm, operation time in the antegrade irrigation group was shorter and the stone-free rate between the two groups was comparable. Conclusion. Antegrade irrigation via percutaneous nephrostomy during ureteroscopy has a higher stone-free rate with a shorter operation time without an increased urinary tract infection risk. Therefore, if percutaneous nephrostomy is necessary before ureteroscopy, antegrade irrigation of external fluid via percutaneous nephrostomy is strongly recommended.

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.
