“…This result is consistent with Ahmed et al . who reported that urinary stone size is usually the same for both US and CT.[ 8 ] The results are also consistent with Sade et al ., who reported that the diagnostic accuracy of US and low dose CT for the diagnosis of urolithiasis in pediatric patients, were 0.68 and 1, respectively. [ 18 ] However, this result was not consistent with the results of Dai et al ., who reported that the mean stone size was 6.8 ± 4 mm for CT and 10.3 ± 4.1 mm for US.…”

“…[ 7 ] The sensitivity of US is low in stones with low-grade hydronephrosis or hydro calyces, and small stones (<3 mm). [ 8 ] The sensitivity of US increases with increasing stone size, but CT is still the gold standard for detecting urinary stones. [ 7 8 ] Measuring the stone size is an important point for planning management.…”

Objective: Due to a lack of studies regarding the need for computed tomography (CT) in measuring the size of each urinary calculus before surgery, this study was conducted to elucidate the difference between ultrasonography (US) and CT in measuring the size of urinary stones. Methods: A retrospective review of 100 stones from 83 patients. Each urinary stone was measured using both US and CT; both measurements were then compared. Results: Of 83 patients, the mean age was 39.29 ± 23.76 years; 47 (56.62%) were male and 36 (43.37%) were female. Most of the urinary stones were <10 mm (50.0%) followed by 11–20 mm (42.0%), ( P < 0.001). A cross-tabulation test revealed strong compatibility between US and CT in measuring the size of urinary stones (73.7% in stones <10 mm, 66.7% in stones 11–20 mm and 50% in stones >21 mm), ( P < 0.001). Spearman's rho correlation test revealed strong compatibility between stone diameters measured by US and CT (r = 0.755), ( P = 0 < 0.001). T-test for equality of means revealed no significant difference in the measured size using US and CT (mean = 11.80 ± 5.83 vs. 11.65 ± 6.59, respectively), mean difference = 0.15, and P = 0.865, 95% confidence interval: -1.584–1.884. Conclusion: No significant difference in measuring the size of urinary stones using US and CT. However, US may slightly overestimate small stones in some cases.

“…Early stone-free rate (SFR) after operation was 90.2% (101 patients) on the first day after operation in accordance with KUB X-ray or US ( 14 ), but 6 patients had residual fragment <5 mm, which passed spontaneously 2 weeks after the operation (total SFR reached 95.3% without any axillary procedure). Three patients underwent second-look nephroscopy, and ureteroscopy was done for two patients due to migrated stone fragments to the distal ureter.…”

Purpose: Renal calculi are becoming more common among children. Although, extracorporeal shock wave lithotripsy (ESWL) is the first choice in this age group, minimal invasive surgeries, such as percutaneous nephrolithotomy (PCNL), are indicated for some patients. Recently, PCNL devices have become smaller in size with acceptable efficacy and lower complications. We evaluated the outcomes and complications of mini-PCNL (MPCNL) surgery in our referral training centers.Materials and Methods: Between September 2012 and January 2020, a total of 112 children under the age of 18, who had shown failure of ESWL, and/or their parents refused to do it, underwent MPCNL (15 Fr). The patients' profiles were reviewed for data collection including preoperative and stone data, operation information, and postoperative complications.Results: Of 112 patients, 69 were boys, and 43 were girls. Their mean age was 8.6 years (14 months to 18 years). Mean stone size was 20 mm (14–34 mm). Seventy-four cases had renal pelvic stone, 22 had pelvis and lower pole, and 16 had staghorn. The mean operation time was 65 min (35–100 min), and mean radiation time was 0.6 min (0.2–1.4 min). Low-grade fever was detected in 14 patients (12.5%). Four patients needed blood transfusion and two had increased creatinine, which improved with conservative management. One patient developed urosepsis that resolved with antibiotic therapy. None of the patients had kidney perforation or other organ injury or death. Early stone-free rate (SFR) after operation was 90.2% (101 patients). Six patients had residual fragment <5 mm, which passed spontaneously in 2 weeks after operation (total SFR 95.3%). Three patients underwent second-look nephroscopy, and ureteroscopy was done for two patients due to migrated stone fragments to the distal ureter.Conclusion: MPCNL is recommended as a safe alternative option for treatment of the nephrolithiasis in children with good outcome and acceptable complications.

“…More commonly seen in patients within age group of 35-45. American guideline recommends CT scan as first choice for ureteric stone diagnosis while European says the ultrasound as the initial modality (4) . Normal renal function is critical because it involves the filtration and excretion of metabolic waste products such as urea and ammonium; electrolyte regulation; fluid and acid-base balance; aids in the formation of red blood cells, which is used to maintain blood pressure through the renin-angiotensin-aldosterone system and to regulate water resorption; and maintain the blood pressure via the renin-angiotensin-aldosterone system and maintain the volume in blood vessels (5) .…”
