ABSTRACT
BACKGROUND: The aim of this study is to report our experience with the Miniperc technique for treatment of renal stone in pediatric age group. MATERIALS AND METHODS: From August 2012 to January 2015, 34 patients aged <15 years with renal stones <3 cm underwent Miniperc technique were included in our study. The procedure was done through 14 Fr sheath using 8/9.8 Fr semi-rigid ureteroscope, holmium laser, and pneumatic lithotriptor for stone fragmentation. Stone-free rate (SFR), operative time, hospital stay, and complication rate were evaluated. RESULTS: A total of 34 Miniperc techniques were performed on children with a mean age of 8.8 ± 3.7 years. Stone size varied from 18 to 30 mm (mean 23 mm). Mean operative time was 50 min. The mean hospital stay was 48±12 hours. The overall SFR was 82.4% which increased after secondary procedures to 94%. Two postoperative complications recorded in the form of sepsis and bleeding that required no blood transfusion. CONCLUSION: Our initial experience concluded that Miniperc technique is a safe and effective treatment option for renal stones in pediatric population.
ABSTRACT
ABSTRACT Background: We analyzed the outcome and complications of rigid (R-URS) and flexible (F-URS) ureteroscopic lithotripsy for treatment of proximal ureteric stone (PUS). Subjects and methods: Retrospective data of 135 patients (93 males and 42 females) submitted to R-URS and F-URS for treatment of PUS in the period between July 2013 and January 2015 were investigated. (R-URS, group 1) was performed in 72 patients while 63 patients underwent (F-URS, group 2).We compared the 2 groups for success, stone characteristics, operative time, intraoperative and postoperative complications. Results: The overall stone free rate (SFRs) was 49/72 (68%) in group 1 and 57/63 (91%) patients in group 2, (P=0.005). The operative time was shorter in group 1 in comparison to group 2 with statistically significant difference (P=0.005). There was not any statistically significant difference between 2 groups in complication rate (P=0.2). Conclusıon: Both R-URS and F-URS could be a feasible option for treatment of PUS. R-URS is less successful for treatment of PUS and should be used cautiously and with availability of F-URS.

PURPOSE: We assess the efficacy and safety of semirigid ureteroscopy for treatment of ureteral stones in children. MATERIALS AND METHODS: The records of 18 non-consecutive children with symptomatic ureteral stones treated with ureteroscopy in 2008-2010 were reviewed. Mean age was 7.6 years (range 15 months-14 years). A semirigid (8F) ureteroscope was used in all cases. A 0.038-inch floppy-tipped guidewire was passed through the selected ureteric orifice, advanced under direct vision, and monitored fluoroscopically. Dilatation of the ureteral orifice was necessary in 7 cases. Either direct extraction or disintegration using a pneumatic lithotripter was performed. The follow-up period was 6 months. RESULTS: Ureteroscopic procedures were successfully completed in 16 children (89%). Stones were located at the middle ureter in 3 (19%) cases and various levels of the lower third ureter in 13 (81%) cases. Stone size was 4-10 mm (mean 7 mm). Stones were fragmented with pneumatic lithotripsy in 9 (56%) cases and removed by forceps without fragmentation in 7 (44%). Stent was left in place for 3 days to 3 weeks in 12 (75%) cases. Early postoperative complications were insignificant hematuria in 2 patients and renal colic and fever in 3 patients. No complications were observed during the period of follow up. CONCLUSION: Ureteroscopy is a feasible treatment option for ureteral stones in children, when in skilled hands and with the aid of experience gained in the adult population.
